Description

Technical Field

[0001] The invention relates to the technical field of trenching processing, in particular to an agricultural planting trenching machine. Background Art

[0002] In the process of agricultural planting, it is necessary to dig trenches in the farmland for burying seeds or applying fertilizers. Generally, trenching is carried out using a trencher, which can significantly improve planting efficiency, reduce labor intensity, and ensure that the depth and width of the trenches are uniform.

[0003] However, when farmland is first used for trenching, there may be many stones and weeds, and the existing trenching machines are unable to clean the stones and weeds in the farmland. The presence of stones and weeds after trenching will affect the subsequent seed burying or fertilization process, and the overall trenching effect is not good. At the same time, the trenching angle of the existing trenching machine is difficult to adjust and cannot meet different trenching needs. Therefore, it is necessary to design an agricultural planting trenching machine. Summary of the invention

The lower left portion of the inner wall of the vehicle body is fixedly connected to the output motor 1, and the output end of the output motor 1 is fixedly connected to the output portion of the belt guide assembly. A plurality of groups of evenly arranged load-bearing beams are provided on the right side of the bottom wall of the vehicle body, a guide inclined plate is fixedly connected to the middle left portion of the inner wall of the vehicle body, and a plurality of groups of evenly arranged front-to-back docking grooves are provided on the left portion of the guide inclined plate.

[0007] Preferably, the linkage turntable is provided with four groups of arc-shaped slide grooves evenly arranged in an annular shape, a group of linkage sliding shafts are slidably connected inside the arc-shaped slide grooves respectively, and the outer end of the rotating shaft of the linkage turntable is fixedly connected to the linkage gear.

[0008] Preferably, the front insertion soil mechanism includes two groups of fixed frames, a driving screw, a nut sub-block, a fixed bearing and two output motors. The two groups of fixed frames are symmetrically fixedly connected to the left middle part of the front and rear side walls of the vehicle body.

[0010] Preferably, the left side of the inner bottom wall of the vehicle body is fixedly connected to the belt conveyor assembly, and two groups of front-to-rear symmetrical gathering inclined plates are arranged on the upper middle part of the inner side wall of the vehicle body.

[0011] Preferably, the top of the fixed frame is fixedly connected with the output motor 2, and the output end of the output motor 2 is fixedly connected with a driving screw.

[0013] Working principle: The vehicle body is fixed on the transport and traction equipment by the load-bearing beam of the main fixing mechanism, the front insertion soil mechanism and the contact ditching mechanism are started, and the main fixing mechanism is driven to move linearly by the traction equipment. During the displacement, the output motor 2 of the front insertion soil mechanism is started, and drives the driving screw installed at its output end to rotate inside the fixed frame. While the driving screw rotates, the nut sub-block connected with its thread begins to descend along the inner wall of the fixed frame, and the two sets of nut sub-blocks simultaneously drive the contact ditching mechanism to descend through the fixed bearings installed on them. While descending, the inside of the vehicle body The output motor installed at the bottom generates rotational torque when it is started, and is guided to the contact ditching mechanism by the belt guide assembly installed at the output end. After the central shaft receives the rotational torque through the belt guide assembly, it rotates along the two sets of fixed bearings. The cylindrical fixed boxes installed on both sides of the central shaft and the four sets of linkage sliding shafts that limit the sliding of the slide groove also rotate counterclockwise. After the transverse array cross ditching arms installed on the four sets of linkage sliding shafts contact the soil in turn, the centrifugally rotating cross ditching arms lift the corresponding row of soil as a whole and rotate centrifugally, and the cross ditching arms rotate and separate from the soil, and the next set of The cross trenching arm corresponding to the linkage sliding shaft begins to insert into the soil, which is convenient for trenching at different angles. Then the cross trenching arm rotates one circle, and the cross trenching arm contacts the guide inclined plate located on the inner wall of the vehicle body, and passes through the guide inclined plate through the docking groove installed on the guide inclined plate. The soil falls on the guide inclined plate and slides along the inclined guide inclined plate to the belt conveyor assembly, where it is transported by the belt conveyor assembly and positioned by the gathering inclined plate installed above the belt conveyor assembly. Finally, it falls into the vehicle body, and the output motor installed on the central rotating shaft can also be started according to the planting row spacing. Third, after the output motor three drives the driving gear installed on its output end to rotate, the linkage gear meshing with the driving gear drives the fixed linkage turntable to rotate inside the driving gear, and the four sets of arc-shaped slide grooves installed on the linkage turntable also rotate accordingly, and at the same time, the four sets of linkage sliding shafts slidingly connected to the arc-shaped slide grooves also move outward or inward along the limiting slide grooves along with the rotation of the arc-shaped slide grooves, so that the diameter of the rotating excavation of the contact trenching mechanism is reduced or increased, and in conjunction with the descending and lifting driving distance of the front insertion mechanism, the contact trenching mechanism can facilitate trenching at different angles.

[0014] The present invention provides an agricultural planting trenching machine, which has the following beneficial effects: After the central rotating shaft of the present invention receives the rotational torque through the belt guide assembly, it rotates along the two groups of fixed bearings, and the cylindrical fixed boxes installed on both sides of the central rotating shaft and the four groups of linked sliding shafts that limit the sliding of the slide grooves also rotate counterclockwise. After the transverse array cross-grooving arms installed on the four groups of linked sliding shafts contact the soil in turn, the centrifugally rotating cross-grooving arms will lift the corresponding row of soil as a whole and centrifugally rotate, and the cross-grooving arms will rotate and separate from the soil, and the cross-grooving arms corresponding to the next group of linked sliding shafts begin to insert into the soil, which is convenient for grooving at different angles, and so on. Uninterrupted grooving is performed by the rotating contact grooving mechanism, thereby improving the grooving efficiency.

[0015] The present invention starts the output motor three installed on the central rotating shaft according to the planting row spacing. After the output motor three drives the driving gear installed on its output end to rotate, the linkage gear meshing with the driving gear drives the fixed linkage turntable to rotate inside the driving gear, and the four groups of arc-shaped slide grooves installed on the linkage turntable also rotate accordingly. At the same time, the four groups of linkage sliding shafts slidably connected to the arc-shaped slide grooves also move outward or inward along the limiting slide grooves along with the rotation of the arc-shaped slide grooves, so that the diameter of the rotating excavation of the contact trenching mechanism is reduced or increased. In conjunction with the descending and lifting driving distance of the front insertion mechanism, the contact trenching mechanism can facilitate trenching at different angles.
