Description

A barrel-type pit-digging and fertilizing soil-covering device

technical field

The utility model relates to a cylinder-type pit-digging, fertilizing, and soil-covering device, which is particularly suitable for the application fields of digging pits, fertilizing, and soil-covering in agricultural and forestry orchards, and belongs to the field of agricultural machinery research.

Background technique

At present, there are many known garden fertilizing machines, some of which are machines for ditching and fertilizing, such as the announced garden offset type ditching, fertilizing and soil-burying machine (patent number: 201020270948.6), the design analysis and analysis of the miniature orchard ditching machine. Optimization (Chinese Excellent Master's Thesis Agricultural Science and Technology Series 2010, No. 11), it all adopts ditching in the orchard, then fertilizes, and finally covers the soil to complete the homework. The other part is used to adopt the drilling type digging, such as tree planting digging machine (application publication number: CN102613048A), which can realize the digging operation.

But the above-mentioned machinery for digging pits, fertilizing and covering soil has the following deficiencies and disadvantages: the ditching type machinery consumes a large amount of useless power when ditching, and it takes up a lot of space when it works, and its use is limited; The machinery fails to realize automatic soil covering operation, and fails to achieve a good matching operation with small tractors, resulting in high labor intensity.

Contents of the invention

In order to overcome the deficiencies and defects existing in the prior art, the purpose of the utility model is to provide a cylinder type soil cover device for excavating pits and fertilizing. It can not only meet the above requirements, but also has high operating efficiency and stable operating quality, and can collect the virtual soil on the drill bit belt into the space of the inner shell, which greatly improves the working environment. The technical solution adopted by the utility model to solve the technical problems is a cylinder-type digging and fertilizing soil covering device, which includes a drill bit 1, a transmission 5, a frame 6, a fertilizer pipe 7, a soil box shell 10, a shell support plate 11, and a soil box The inner shell 12, the drill bit 1 and the lead screw 3 are coaxially welded, the transmission 5 shell is fixed on the frame 6, the fertilizer pipe 7 is embedded in the soil box, the shell support plate 11 and the soil box shell 10 hinged, the soil box inner shell 12 is welded with the soil box shell 10 through steel pipes;

It is characterized in that: the rhombic rod 4 is connected to the output shaft of the transmission 5, the lead screw 3 is connected to the rhombic rod 4, and the input node and the output node of the rhombic rod 4 are opposite, and the nut 2 is fixed to the earth box shell 10 directly above, and the nut 2 and the lead screw 3 match;

One side of the parallelogram mechanism 9 is fixed to the frame 6, and the other symmetrical side is hinged to the soil box shell 10. There are two left and right parallelogram mechanisms 9 in this device, and three-point suspension upper rod 8 forms three points Suspension, the three-point suspension upper tie rod 8 is hinged to the soil box shell 10.

The fertilization pipe 7 is embedded in the soil box, and when the digging process is completed, the fertilizer is transported into the soil pit through the fertilizer pipe.

When the inner shell moves up under the action of the three-point suspension pull-up rod 8, a gap is formed between the inner shell 12 of the soil box and the outer shell support plate 11, and then the virtual soil falls into the soil pit along the gap to realize soil covering Operation.

The working principle of a barrel-type pit digging and fertilizing soil covering device of the utility model is as follows:

First of all, fix the three-point suspension device and the transmission composed of the parallelogram mechanism and the three-point suspension top rod to the matching tractor before work, and then adjust the device to contact with the ground and fix it through the three-point suspension top rod, and then start The tractor turns the transmission, the output shaft of the transmission drives the rhombus rod to rotate and at the same time the rhombus rod moves down, and the rhombus rod drives the lead screw to rotate. Since the nut is fixed, the lead screw not only rotates but also moves down, and the lead screw drives the drill bit at the same time Rotate and move down, at this time the digging operation is realized. After the digging is completed, change the rotation direction of the screw to make the drill bit return to the original position. At the same time, the virtual soil falls into the space formed by the inner shell; Open it, and transport the fertilizer to the soil pit through the fertilizer pipe to realize the fertilization operation; finally, use the three-point suspension pull-up rod to move the inner shell up. The virtual soil in the hole flows back into the pit along the gap to realize the soil covering operation.

The beneficial effect of the utility model is that the device can be used in conjunction with a small tractor, and when used in an orchard, it occupies a small area and has low labor intensity, and can greatly improve work efficiency and work quality.
