Description

Technical Field

[0001] This utility model belongs to the field of agricultural planting ditching technology, and specifically relates to an agricultural planting ditching machine. Background Technology

[0002] In recent years, the level of automation and mechanization in agricultural planting has been increasing, including mechanized plowing, tilling, ditching, sowing, weeding, fertilizing, and spraying. Among these, the planting ditching needs to be controlled in terms of depth, width, and spacing according to the different types of crops and planting requirements.

[0003] A search revealed an existing technology announcement number CN221768694U for an agricultural planting ditching machine. This utility model features a root-removing claw at the upper end of the ditching turntable. When the rotary tillers on the ditching turntable pass through the root-removing claw, the roots are bent and deformed by the claw hook and separated from the rotary tillers. The roots are intercepted by the claw hook and accumulate at the bottom of the claw hook. Because the bottom of the claw hook has a certain slope, the accumulated roots can slide to the side, thereby transferring the roots in the ditch to the outside of the ditch for convenient centralized processing and subsequent crop planting.

[0004] However, the above scheme also has certain drawbacks. The position of the trenching turntable is fixed and cannot be adjusted, so the distance between the two turntables cannot be changed. However, the planting requirements of different plants are not the same, including the width, depth and spacing of the trench. The above scheme cannot adjust and control the trench spacing and depth, making its applicable range narrow.

[0005] Further research revealed an agricultural ditching machine with the existing technology announcement number CN218868655U. This machine moves the ditching disc by manually holding a handle and driving a walking roller. A servo motor is engaged with the drive roller to enable the ditching disc to perform ditching during movement. The ditching disc's depth can be freely adjusted by the rotating shaft, thus regulating the ditching depth. This mechanical adjustment simplifies the overall structure of the equipment, making it easier to operate and reducing operating costs.

[0006] This scheme has the same drawbacks as mentioned above: it cannot adjust and control the trench spacing and width, and the applicable plant species range is relatively narrow. Summary of the Invention

[0007] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an agricultural planting ditching machine that can adjust the ditch width and control the ditch spacing through the first and second plow blades in conjunction with the adjustment and control components. Furthermore, it can also control and adjust the ditch depth by rotating the lead screw to drive the main shaft to adjust the height.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0009] An agricultural planting ditching machine includes a frame, a main shaft, a first plow blade, a second plow blade, an adjustment component, a control component, and a gearbox. The main shaft is rotatably connected to the frame at both ends and has keyways and positioning holes. The gearbox is fixed to the frame and connected to the main shaft via gears. The output end of the gearbox has a universal joint and is connected to an external traction machine providing power. A pair of first plow blades are symmetrically arranged on both sides of the gearbox. The first plow blades are sleeved on the main shaft, and the second plow blades are inserted into the first plow blades, allowing for combination and separation to control the ditch width. The adjustment component is located on one side of the second plow blades to control the insertion depth of the second plow blades within the first plow blades. The control component is located on one side of the first plow blades and, in conjunction with the keyways and positioning holes, controls the position of the first plow blades on the main shaft to adjust the ditch spacing.

[0010] The frame is provided with a traction frame that is rotatably connected. The traction frame is provided with a support plate. The support plate is provided with a slot. The slot is provided with a mounting block that is rotatably connected to the support plate via a rotating shaft. The mounting block is provided with a screw that is threadedly connected. One end of the screw is provided with a fixed seat that is rotatably connected. One side of the fixed seat is provided with a support platform that is rotatably connected. The support platform is fixedly connected to the frame.

[0011] The first plow blade has several blades and is fixedly connected to the first mounting cylinder. The first mounting cylinder and the first plow blade are hollow. A second sleeve is provided inside the first mounting cylinder. The outer wall of the second sleeve is threaded. The second sleeve is hollow and has a key on its inner wall. The second sleeve is sleeved to the main shaft. The key is located in the keyway to restrict rotation. A third sleeve is fixedly connected to one side of the first mounting cylinder. A first limiting flange is provided at the end of the third sleeve. The third sleeve is fixedly connected to the first sleeve and slidably connected to the limiting shaft. One end of the limiting shaft is slidably connected to the second sleeve. One end of the limiting shaft is provided with a horizontal shaft and the other end is provided with a top plate. A spring is sleeved on the limiting shaft. The spring touches the top plate and the inner wall of the first sleeve.

[0012] The second plow blade is fixedly connected to the first plow blade and the second mounting cylinder. The second plow blade and the second mounting cylinder are inserted into the first plow blade and the first mounting cylinder. The second mounting cylinder is sleeved with the second sleeve. The end of the second mounting cylinder is provided with a second limiting flange.

[0013] The control assembly includes a control panel, which is assembled by dividing components and fixing them with bolts to facilitate disassembly and installation; the control panel is provided with a wedge block, and the control panel is located on the third sleeve and is blocked on one side of the first limiting flange to prevent the control panel from slipping off;

[0014] The adjustment assembly includes a rotating sleeve and a retaining ring, which are fixed together by bolts. The inner wall of the rotating sleeve is threaded, and the rotating sleeve is fitted onto the second sleeve and connected to each other by the threads. The retaining ring is fitted onto the second mounting sleeve and is blocked on one side of the second limiting flange to prevent slippage. The retaining ring is also assembled using the same method as the control panel segmentation assembly, which facilitates disassembly and installation.

[0015] The advantages of this utility model compared with the prior art are as follows:

[0016] 1) The external traction machine is connected through the traction frame. The output end of the gearbox is connected to the external traction machine to provide power to drive the main shaft to rotate, which in turn drives the first plow blade and the second plow blade to rotate to open trenches. The spring pushes the top plate to drive the limit shaft to pass through the third sleeve and enter the positioning hole to fix the position of the first plow blade. The second plow blade is fixed on the second sleeve by the rotating sleeve in the adjustment component. Thus, the positions of the first and second plow blades on the main shaft and the insertion depth between the plow blades are set and installed by the cooperation of the adjustment component and the control component.

[0017] By rotating the rotating sleeve, the retaining ring pulls the second limiting flange and the second mounting cylinder along the second sleeve, thereby achieving the insertion depth of the second plow blade in the first plow blade, thus enabling the control of the width between the first and second plow blades, and ultimately achieving the adjustment and control of the trench width.

[0018] 2) By rotating the control panel, the wedge block supports the horizontal axis, causing the limit shaft to rise and be lifted, thus disengaging from the insertion restriction of the positioning hole. Then, the first plow blade is pushed to slide along the keyway, achieving the effect of adjusting the distance between the two sides of the groove. Then, the control panel is reversed, causing the spring to push the limit shaft back to the insertion positioning hole, thus fixing the position of the first plow blade and completing the final adjustment. The control panel can simultaneously control the release of the insertion relationship between multiple limit shafts and positioning holes, which is convenient and quick, avoiding the drawback of requiring multiple people to operate.

[0019] 3) The angle can also be adjusted by rotating the screw to pull the frame, thereby raising and lowering the main shaft, which can realize the height adjustment of the first plow blade, thereby realizing the adjustment and control of the trenching depth. The rotation setting between the mounting block and the support plate, and the rotation setting between the fixed seat and the support platform, can enable the frame to smoothly realize the angle conversion and change between the screw and the support platform when the screw rotates, so that the control and adjustment of the trenching depth can be smoothly realized.
