The end part of the side sill 1020 is fixedly provided with a U-shaped auxiliary beam 1030 in a downward manner, a side supporting plate 1031 is fixedly arranged on the outer side of the U-shaped auxiliary beam 1030, an inclined plane groove is formed in the side supporting plate 1031, the inclined plane groove comprises a proximal inner inclined plane 1027 and a distal outer vertical plane 1028, and a turnover supporting shaft 1029 is arranged at the top of the outer vertical plane 1028. A U-shaped seat 1026 is fixed to the outer end of the flip support shaft 1029.
Based on the above-described structure, the present embodiment can realize three state changes as shown in fig. 9, namely, the outward expansion of the side boom 1013, the inward retraction of the side boom 1013, and the vertical inversion of the side boom 1013. As shown in fig. 6, when the width of the middle spray bar 1011 is a and the width of the side spray bar 1013 is b, the length of the width l of the whole spray bar is a.ltoreq.l.ltoreq.a+2b, so that the width of the soybean spray can be covered with a to a+2b, or when the soybean and the corn are interplanted, the soybean with the middle width of a is matched with the width of b corn, or when the corn and the soybean have a height difference, the width of the corn spray on the two sides can be independently b. As shown in FIG. 9 ①, when the corn plants are significantly higher, the side boom 1013 is erected with a height in the range of b, and corn can be sprayed from the side. The vertical overturning function of the side spray rod frame enables the spraying system to automatically adjust the spraying angle and the spraying width according to the growth stage or the planting mode of crops, and a more flexible spraying solution is provided. Particularly, when soybean and corn are interplanted, the spraying width and angle can be adjusted to meet the spraying requirements of different crops.
The expansion and contraction of the side spray rod frame can be realized through the expansion control of the third electric push rod, so that the spraying width is accurately adjusted, the spraying range is ensured to be matched with the growth state of crops, the resource waste is reduced, and the spraying efficiency is improved. As shown in fig. 9 ②, when the third electric putter 1019 is controlled to be extended forward, the side boom 1013 in the contracted state can be changed to the extended state, or when the third electric putter 1019 is controlled to be contracted, the side boom 1013 in the extended state can be changed to the contracted state. As shown in fig. 9 ①, in the extended state, as the distal end of third electrical push rod 1019 is controlled to continue to move outward, push-pull shaft 1023 is constrained by diagonal guide rod 1025 such that push-pull shaft 1023 slides down the diagonal surface of diagonal guide rod 1025 into the diagonal surface groove. At the same time, the lower slide bar 1022 is forced to turn upward under the supporting action of the turn supporting shaft 1029. Eventually, the push-pull shaft 1023 falls into the groove bottom position formed by the inclined surfaces. A stop lever 1032 is fixed to the top of the lower rail groove 1021 and serves as a stop table to prevent the side boom 1013 from turning over inward.
During the upward turning of the turning support shaft 1029, the entire side boom 1013 is turned along the axial center of the push-pull shaft 1023. So that the upper slide bar 1033 also turns upwards, the upper slide bar 1033 will slide along the through hole of the turning block 1037 when turning over, and the turned upper slide bar 1033 will push the turning block 1037 to move inwards, so as to compress the spring 1039 through the sideslip column 1036. Finally, the flip block 1037 is resiliently biased against the outside of the upper slide bar 1033. D1, d2 and d3 in fig. 9 represent the lengths of the different loading springs 1039, respectively. The design of the overturning block, the spring and the overturning supporting shaft ensures the stability and the reliability of the spraying system in the overturning process. The overturning block can be overturned freely, and the upper sliding rod can be ensured to move stably through the elastic support of the spring, so that excessive overturning or misoperation is avoided, and the operation safety of the system is improved.
The spraying system can avoid excessive application, reduce medicament waste, improve spraying uniformity and accuracy, ensure accurate application of pesticides or fertilizers and improve overall benefits of agricultural production. According to the system, the overturning and adjusting functions are realized through the matching of the structural components, and the system is simple and convenient in design and visual in operation. The inclined surface groove, the limiting rod and the like are designed to effectively guide the movement of the spraying frame, so that complex operation steps are reduced, the possibility of faults is reduced, and the spraying frame is convenient to maintain and operate daily. Through the nimble adjustment of multiple spraying mode, can accurate coverage crop required area, improve and spray effect and efficiency, reduced the waste of spraying medicament or fertilizer, practiced thrift pesticide use cost.
Based on the scheme, the use process of the spraying system with the vertical overturning function additionally arranged by the side spray boom frame is as follows. Firstly, the components of the spray frame are ensured to be well installed, in particular to key components such as an electric push rod, a push-pull shaft, a spring, a turnover block and the like. Checking whether the liquid path is smooth or not, and whether the spray pipe is firmly connected or not. After the system is prepared, the spraying frame has a good working state, and the spraying operation can be ensured to be smoothly carried out. Then, the controller is used to adjust the expansion and contraction of the third electric putter 1019 to adjust the side boom 1013 to an expanded or contracted state according to the growing stage of the crop and the area to be sprayed. At this time, the spraying system can adjust the spraying width according to the width of crops or the land requirement, ensure that the spraying range covers the required area of crops, avoid excessive spraying or omission, and improve the spraying efficiency. When the height of crops such as corn is high or the crops need to be sprayed from the side, the third electric push rod 1019 is started to control the side spray rod frame to turn over vertically. Side boom is flipped in place along flipping support shaft 1029, guided by push-pull shaft 1023 and diagonal guide 1025. The spraying frame can be adjusted to be in an upright state (shown as ① in fig. 9) in the overturning process, so that the spraying pipe can spray from the side surface, the spraying frame is suitable for the spraying requirements of high crops such as corn and the like, and the spraying uniformity and coverage range are ensured. By operating the turning block 1037 and the spring 1039, the spray angle is continuously adjusted, so that the spray pipe 105 can be accurately aligned with crops, and waste is avoided. If finer spraying is needed, the spraying width and the spraying angle can be further adjusted according to the height and the growth condition of crops. After the spray task is completed, the controller is used to retract the third electric push rod 1019, so that the side spray rod frame returns to the original horizontal state from the vertical state. At this time, the push-pull shaft 1023 is driven by the inclined guide rod 1025 to re-enter the lower rail groove 1021, and the side spray bar is restored to the original state. The system is restored to a contracted state, so that the equipment can be stored or transferred to the next spraying area conveniently, the occupied space is reduced, and the safety of the equipment is ensured.
After each use, the abrasion condition of each part of the spraying system is checked, so that the parts such as the spring, the sliding rail, the overturning block and the like are ensured to be free from abnormality, the liquid path is smooth, and the electric push rod works normally. Periodic inspection and maintenance helps to extend the useful life of the device, ensuring that the spray system is in optimal operation for each use.
The above detailed description of the present invention is merely illustrative or explanatory of the principles of the invention and is not necessarily intended to limit the invention. Accordingly, any modification, equivalent replacement, improvement, etc. made without departing from the spirit and scope of the present invention should be included in the scope of the present invention.
