[0002] Crop planting refers to the process of cultivating and growing various agricultural crops in farmland or other suitable arable land under suitable environmental conditions through sowing or transplanting. This process includes selecting suitable crop varieties, preparing soil, sowing or transplanting, fertilizing, irrigation, pest control, field management, harvesting and other links.

[0003] In agricultural production, furrowing, sowing and covering soil are common operations in planting operations. In the traditional crop planting process, manual or mechanical furrowing is generally used, followed by manual sowing and finally mechanical covering soil. This operation method is cumbersome, labor-intensive and labor-intensive, which affects the efficiency of crop planting. Utility Model Content

[0004] The utility model aims to provide a ditching and soil covering device which can perform ditching, sowing and soil covering at the same time, thereby improving the planting efficiency.

[0005] To achieve the above-mentioned purpose, the technical solution of the utility model is as follows.

[0006] A trenching and soil covering device comprises a frame, a plurality of mounting plates are arranged on the upper surface of the frame, a soil breaking plate is arranged on one side of the bottom of the mounting plate, a soil covering plate is arranged on the other side of the bottom of the mounting plate, and a barrel is installed on the mounting plate between the soil breaking plate and the soil covering plate. A shell is installed at the bottom of the barrel, a slider is slidably installed inside the shell, a through hole A is provided inside the slider, a guide rod is connected to the outer surface of the slider, the end of the guide rod passes through the outer side of the shell and is installed with an extrusion block, a spring A is sleeved on the outer surface of the guide rod, the two ends of the spring A are respectively in contact with the shell and the extrusion block, and a through hole B is provided at the bottom of the shell. A camshaft is rotatably installed on the top of the frame, and the outer edge of the camshaft is in contact with the extrusion block, and walking wheels are installed at both ends of the camshaft.

[0007] It can be seen that the device is towed by a tractor, the breaking plate digs trenches on the front side, and the seeds inside the barrel fall into the through hole A. As the walking wheel rotates, it drives the camshaft to rotate, and the camshaft continuously squeezes the extrusion block, causing it to drive the slider to move back and forth. When the slider moves to the other side, through hole A corresponds to through hole B, so that the seeds inside through hole A fall from through hole B and enter the groove, and then the covering plate covers the soil on the back side, thereby completing the purpose of digging trenches, sowing and covering soil at the same time, improving planting efficiency, and the sowing frequency changes with the moving speed of the device, thereby reducing seed waste.

[0008] Furthermore, a groove is provided inside the slider, an extension tube is arranged inside the groove, and the extension tube is arranged coaxially with the through hole A, a spring B is provided inside the groove, a lifting plate is provided inside the shell, a screw A passes through the inside of the shell and is threadedly connected, the end of the screw A is rotatably connected to the lifting plate, and a through hole C is provided on the lifting plate.

[0009] By setting the extension tube, the number of seeds sown can be expanded. When the screw A is rotated, it can drive the lifting plate to rise and fall in the shell, thereby changing the telescopic length of the extension tube. Therefore, the number of seeds sown each time can be adjusted to adapt to the planting of different crops.

[0010] Furthermore, a material guide pipe is installed on the lower surface of the lifting plate, and the material guide pipe passes through the through hole B and extends to the outside of the shell, and the through hole C, the material guide pipe and the through hole B are coaxially arranged.

[0011] By setting the guide tube, the seeds can be guided to prevent the seeds from entering the gap between the lifting plate and the inner wall of the shell when falling.

[0012] Furthermore, a ball bearing is arranged on the lower surface of the extension tube.

[0013] By setting the ball, the friction between the bottom of the extension tube and the lifting plate can be reduced, thereby improving the smoothness.

[0014] Furthermore, a screw rod B is rotatably installed on one side of the upper surface of the breaking plate, and the upper end of the screw rod B passes through the upper side of the mounting plate and is threadedly connected thereto. A limiting rod is installed on the other side of the upper surface of the breaking plate, and the upper end of the limiting rod passes through the upper side of the mounting plate.

[0015] Since the breaking plate is limited by the limiting rod, when the screw rod B is rotated, the breaking plate can be driven to rise and fall, thereby adjusting the trenching depth.

[0016] Furthermore, a plurality of mounting holes A are provided on both sides of the upper surface of the frame, and bolts matching the mounting holes A are installed on the mounting plate.

[0017] By setting the mounting holes A and the bolts, the number of mounting plates and the distance between two adjacent mounting plates can be adjusted to meet the planting requirements of different crops.

[0018] Furthermore, a connecting frame is installed on the outer surface of the frame, and a mounting hole B is opened at the end of the connecting frame.

[0019] By providing the connecting frame and the mounting hole B, the device can be conveniently connected to the tractor.

[0020] Furthermore, knobs are installed at the ends of screw rod A and screw rod B, and anti-slip grooves are provided on the outer surfaces of the knobs.

[0021] The setting of the knob makes it easy to rotate the screw A and the screw B, and the setting of the anti-slip pattern can increase the friction with the hand and reduce the risk of hand slippage. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] The utility model is described in detail below with reference to the accompanying drawings.

[0029] like Figure 1-5As shown, a trenching and covering device includes a frame 100, a plurality of mounting plates 101 are arranged on the upper surface of the frame 100, a soil-breaking plate 102 is arranged on one side of the bottom of the mounting plate 101, a soil-covering plate 103 is arranged on the other side of the bottom of the mounting plate 101, and a barrel 104 is installed on the mounting plate 101 between the soil-breaking plate 102 and the soil-covering plate 103. A housing 105 is installed at the bottom of the barrel 104, a slider 106 is slidably installed inside the housing 105, a through hole A107 is opened inside the slider 106, a guide rod 108 is connected to the outer surface of the slider 106, the end of the guide rod 108 penetrates the outer side of the housing 105 and is installed with an extrusion block 109, a spring A110 is sleeved on the outer surface of the guide rod 108, and the two ends of the spring A110 are respectively abutted against the housing 105 and the extrusion block 109, and a through hole B113 is opened at the bottom of the housing 105. A camshaft 111 is rotatably mounted on the top of the frame 100 , and the outer edge of the camshaft 111 abuts against the extrusion block 109 , and travel wheels 112 are mounted on both ends of the camshaft 111 .

[0030] When in use, first pour the seeds into the barrel 104, then connect the device to the tractor, and the tractor pulls the device. During the traction process, the soil-breaking plate 102 digs a ditch at the front side, and the walking wheel 112 rotates as the device moves. The walking wheel 112 drives the camshaft 111 to rotate. The camshaft 111 squeezes the squeezing block 109 during the rotation process, and then pushes the slider 106 to move. Since the seeds inside the barrel 104 fall into the through hole A107 due to gravity, when the slider 106 moves, it can move with the seeds inside the through hole A107, and the upper surface of the slider 106 can block the bottom of the barrel 104 to prevent the seeds from continuing to fall. When the through hole A107 moves When it moves to the top of the through hole B113, the seeds inside it fall into the groove through the through hole B113, thereby completing the purpose of sowing, and then the covering plate 103 on the rear side can carry out the soil covering operation; when the cam part of the camshaft 111 is away from the extrusion block 109, the compressed spring A110 releases the elastic force to push the slider 106 to reset, so that the through hole A107 returns to the bottom of the barrel 104, and the center of gravity of the seeds inside the barrel 104 falls into the through hole A107. Therefore, during the movement of the device, the slider 106 can be driven to move back and forth and intermittent sowing can be carried out. The faster the device moves, the higher the frequency of sowing. The two adapt to each other, which can reduce seed waste and improve planting efficiency.

[0031] Specifically, a groove 200 is provided inside the slider 106, an extension tube 205 is arranged inside the groove 200, and the extension tube 205 is coaxially arranged with the through hole A107, a spring B201 is arranged inside the groove 200, a lifting plate 202 is provided inside the shell 105, a screw A203 passes through the inside of the shell 105 and is threadedly connected, the end of the screw A203 is rotatably connected to the lifting plate 202, and a through hole C204 is provided on the lifting plate 202. By setting the extension tube 205, the number of seeds sown can be expanded. When the screw A203 is rotated, it can drive the lifting plate 202 to rise and fall in the shell 105, thereby changing the telescopic length of the extension tube 205. Therefore, the number of seeds sown each time can be adjusted, which can be adapted to the planting of different crops.

[0032] Specifically, a material guide tube 300 is installed on the lower surface of the lifting plate 202, and the material guide tube 300 extends to the outside of the shell 105 through the through hole B113, and the through hole C204, the material guide tube 300 and the through hole B113 are coaxially arranged. Through the arrangement of the material guide tube 300, the seeds can be guided to prevent the seeds from entering the gap between the lifting plate 202 and the inner wall of the shell 105 when falling.

[0033] Specifically, a ball 400 is disposed on the lower surface of the extension tube 205. The arrangement of the ball 400 can reduce the friction between the bottom of the extension tube 205 and the lifting plate 202, thereby improving the smoothness.

[0034] Specifically, a screw B500 is rotatably installed on one side of the upper surface of the breaking plate 102, and the upper end of the screw B500 passes through the upper side of the mounting plate 101 and is threadedly connected thereto. A limiting rod 501 is installed on the other side of the upper surface of the breaking plate 102, and the upper end of the limiting rod 501 passes through the upper side of the mounting plate 101. Since the breaking plate 102 is limited by the limiting rod 501, when the screw B500 is rotated, the breaking plate 102 can be driven to rise and fall, and the trenching depth can be adjusted.

[0035] Specifically, multiple mounting holes A600 are opened on both sides of the upper surface of the frame 100, and bolts 601 compatible with the mounting holes A600 are installed on the mounting plate 101. Through the setting of the mounting holes A600 and the bolts 601, the number of mounting plates 101 and the distance between two adjacent mounting plates 101 can be adjusted to meet the planting needs of different crops.

[0036] Specifically, a connecting frame 700 is installed on the outer surface of the frame 100, and a mounting hole B701 is opened at the end of the connecting frame 700. Through the arrangement of the connecting frame 700 and the mounting hole B701, the device can be conveniently connected to the tractor.

[0037] Specifically, knobs 800 are installed at the ends of screw A203 and screw B500, and anti-slip grooves are provided on the outer surface of knob 800.
