detailed description

As shown in Figure 1 to Figure 3 of the small-sized articulated multifunctional fertilizer applicator of present preferred embodiment, the chassis 2 that front end has hanging interface 1 is supported on the walking wheel 7, and bucket-shaped fertilizer box 3 is housed on the chassis 2. The bottom of fertilizer box 3 is equipped with the conveyer belt 4 that is surrounded on the front and rear conveying roller 4-1, and the fertilizer stirring roller 5 that is positioned at conveyer belt 4 tops is equipped with at the rear end of fertilizer box 3 bottoms. A fertilizer outlet channel S is formed between the rear end of the conveyor belt 4 and the rear side wall of the fertilizer box (see FIG. 4 ). One of the conveying rollers 4-1 is connected to the wheel shaft 7-2 of the road wheel 7 through the first chain transmission mechanism 7-1, and is driven by the second chain transmission mechanism 5-1 and the roller shaft 5-2 of the fat stirring roller 5. connect. The rear of the bottom of the fertilizer box 3 is equipped with a hydraulic motor 10 as a rotary power source through a vertical axis fertilizer spreader 8 driven by a third chain transmission mechanism 10-1. The upper surface of the fertilizer spreader 8 has a radial fertilizer plate 8-1. The rear side wall 3-1 of the fertilizer box 3 is equipped with a lift baffle 9 with a guide slot in the middle, and the lower end of the lift baffle 9 forms a guide arc, and the bottom of the rear side wall 3-1 has a fertilizer outlet 3-A, which can be lifted and lowered. The bottom of the baffle plate 9 has a fertilizer guide port 9-A. When the lifting baffle 9 falls to the lower limit position, the fertilizer outlet 3-A and the fertilizer guide port 9-A are staggered and blocked from each other, and the fertilizer outlet channel S is fully opened, forming a smooth fertilizer drop from the conveyor belt 4 to the fertilizer outlet channel S channel (see the position status shown by the dotted line in Figure 4). When lifting the lifting baffle plate 9 slightly upwards, the fertilizer outlet 3-A and the fertilizer guide port 9-A still block each other, the fertilizer outlet channel S becomes smaller, and the fertilizer output decreases, so the amount of fertilizer output can be adjusted. When the lifting baffle 9 is raised to the upper limit position, the fertilizer outlet channel S is closed, the fertilizer outlet 3-A is aligned with the fertilizer guide port 9-A, and the fertilizer transported by the conveyor belt can be aligned with the fertilizer guide port 3-A. The channel output formed by port 9-A falls on the fertilizer spreading disc 8, that is, the fertilizer delivery channel from the conveyor belt 4 to the fertilizer spreading disc 8 is formed (see the position state shown by the solid line in Figure 4).

When fertilizing, it is articulated with a small tractor, and the traveling wheel 7 is used as a power source for fertilizer delivery, and the conveyor roller 4-1 at one end of the conveyor belt is driven by a sprocket drive, thereby driving the conveyor belt 4 at the bottom of the fertilizer box 3 to drive, and driving the conveyor belt with radial agitation. The fertilizer stirring roller 5 of knife 5-3 rotates, thereby the fertilizer is delivered to the fertilizer passage and loosened. When strip application is required, the lifting baffle 9 is at the lower limit position, the fertilizer outlet 3-A and the fertilizer guide port 9-A are mutually blocked, and the fertilizer output by the conveyor belt 4 falls to the ground from the opened fertilizer outlet channel S, realizing fertilizer The fertilizer in the box is continuously and evenly applied to the soil surface. If the furrowing plow is fixedly connected to the front end of the frame, a ditch is first opened on the soil surface, and the fallen fertilizer transported by the conveyor belt can fall into the ditch with the help of the guide plate to realize ditching and strip application. When the lifting baffle 9 is raised to the upper limit position, the fertilizer outlet channel S is closed, and the fertilizer transported by the conveyor belt is output through the channel formed by the aligned fertilizer outlet 3-A and the fertilizer guide port 9-A, and falls on the fertilizer spreading plate 8 , the fertilizer spreader 8 driven to rotate can rotate at a high speed to realize the function of evenly spreading the granular fertilizer.

Therefore, this embodiment can not only realize the two main functions of ditching and spreading, so as to meet the fertilization requirements of different facility agricultural crops, but also the switching operation of the two main functions uses the lifting baffle to adjust the amount of fertilization, and the structure is simple , no need to disassemble and replace parts, the operation is very convenient, and the work efficiency is significantly improved.

In addition to the above embodiments, the utility model can also have other implementations. For example, the lifting baffle can also only have the function of adjusting the amount of fertilization, and the fertilizer spreader is designed as an easy-to-detach structure or a structure that can be moved back and forth. When strip application is required, remove the fertilizer spreader or move it backward, and the fertilizer will fall directly to the ground through the fertilizer outlet channel; It falls on the fertilizer spreader and is then centrifugally thrown. All technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the utility model.
