Description

Technical Field

[0001] This utility model relates to the field of farmland ditching technology, specifically a ditching machine for soybean planting. Background Technology

[0002] The soybean planting trencher is an agricultural machine specifically designed for soybean planting. It uses mechanical power to drive the working parts to dig planting trenches in the field at a specific depth and width, providing a stable implantation space for the seeds and avoiding the impact of sowing too deep or too shallow on seedling emergence. It can change the inefficient mode of traditional manual trenching and realize the mechanized and continuous operation of soybean planting from trenching to sowing.

[0003] There are various types of existing soybean planting trenching machines, which typically include chain trenchers, disc trenchers, tracked trenchers, wheeled trenchers, and small trenchers. Due to considerations of planting costs, small trenchers are the most widely used. Existing small trenchers are usually hand-held, relying on manual pushing to move them in the field, and working with rotary tillers and plow blades to dig trenches suitable for soybean planting requirements.

[0004] Existing small trenchers do not have the function of bidirectional trenching. When excavating different rows of trenches, it is often necessary to manually lift the entire machine to turn it 180°. However, the trencher is equipped with a diesel generator set, which is quite heavy. The process of turning the machine around puts a heavy burden on the manual laborers and increases the fatigue during the trenching process. Utility Model Content

[0005] The purpose of this invention is to provide a trenching machine for soybean planting to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a ditching machine for soybean planting, comprising a ring frame, a cross-shaped cross connected to the inner wall of the ring frame, a diesel generator set mounted on the upper surface of the cross-shaped cross, a motor mounted at the bottom of the diesel generator set, the motor being selected with forward and reverse rotation functions to complete the bidirectional ditching mode of the ditching machine, a connecting frame connected to the bottom of the cross-shaped cross, a rotating shaft connected through the bottom of the connecting frame, and a bearing installed between the rotating shaft and the connecting frame, a rotary tiller blade mounted in the middle of the rotating shaft, a transmission group rotatably connected between the motor and the rotating shaft, the transmission group having the structure of an existing ditching machine, consisting of two transmission wheels and a transmission belt, a slot provided on the upper surface of the ring frame, a steering component installed in the slot for turning the handle and the plow blade, a handle mounted on the top of the steering component, in actual application, a control circuit connection exists between the handle and the motor, the length of the circuit needs to be reserved to facilitate the turning of the handle, a connecting rod connected to the front side wall of the steering component, and a plow blade connected to the bottom of the connecting rod; The steering assembly includes a movable plate movably mounted on the upper surface of the ring frame. A movable block is connected to the bottom of the movable plate. A through hole is formed on one side of the movable plate of the movable block. The position of the through hole corresponds to the position of the positioning hole on the ring edge. An L-shaped plate is connected above the movable plate. A hinge is connected between one side of the movable plate and the L-shaped plate. Two positioning rods are connected to the bottom of the L-shaped plate. The distance between the two positioning rods is the same as the distance between adjacent positioning holes.

[0007] Preferably, the outer wall of the annular frame is connected to an annular edge, and a plurality of positioning holes are provided through the annular edge in a circumferentially equidistant manner. Both the annular frame and the annular edge are circular in shape, and the annular frame provides a basis for the movable plate and the L-shaped plate to make a circular path for turning.

[0008] Preferably, the movable block is an arc-shaped plate with a cross-section of T. The cross-sectional shape of the slot corresponds to that of the movable block. The movable block is inserted into the slot and forms a sliding connection with the ring frame. By sliding the movable block in the slot, the movable plate is driven to switch between the frontmost and rearmost positions of the ring frame.

[0009] Preferably, the movable plate is hinged to the L-shaped plate, so that the L-shaped plate can be flipped upward relative to the movable plate, which facilitates the temporary disengagement of the positioning rod from the positioning groove. The positioning rod corresponds to the position of the through hole and the positioning hole. The positioning rod is inserted through the through hole and the positioning hole. The movable plate is positioned by inserting the positioning rod into the positioning hole, so as to keep the movable plate and the ring frame relatively stationary.

[0010] Preferably, a dust cover is connected to the bottom of the L-shaped plate. The dust cover is in the shape of an arc plate. The arc design of the dust cover can block the soil caused by the rotation of the rotary tiller blades over a large area, protecting the workers from the influence of the soil. The dust cover is located at the bottom of the ring frame.

[0011] Compared with the prior art, the beneficial effects of this utility model are: This ditching machine for soybean planting features a steering component. By pushing the handle upwards, the handle causes the L-shaped plate to flip upwards relative to the movable plate via a hinge. This causes the L-shaped plate to move the positioning rod upwards and pull it out of the positioning hole. Then, by pushing the handle laterally, the movable plate causes the movable block to slide in the slot until the movable plate moves from the frontmost position of the ring frame to the rearmost position. This causes the plow blade and handle to complete the steering, making it easier and more convenient for the ditching machine to turn around. Combined with the motor rotation direction switching, the ditching machine can achieve bidirectional ditching function.

[0012] This ditching machine for soybean planting features a dust cover designed in an arc shape, which effectively blocks soil generated by the rotary tiller blades, protecting workers from soil contamination. In addition, the top of the dust cover is connected to an L-shaped plate, which moves the dust cover synchronously when the handle is turned, allowing the dust cover to be adjusted for different working modes of the ditching machine.

[0017] like Figures 1 to 4As shown, the ditching machine for soybean planting in this embodiment includes a ring frame 1. A cross 2 is connected to the inner wall of the ring frame 1. The cross 2 is cross-shaped and is used to install a diesel generator set 3. The diesel generator set 3 is installed on the upper surface of the cross 2. A motor 4 is installed at the bottom of the diesel generator set 3. The motor 4 is selected to have forward and reverse rotation functions to complete the bidirectional ditching mode of the ditching machine. A connecting frame 5 is connected to the bottom of the cross 2 for installing a rotating shaft 6. The bottom of the connecting frame 5 passes through and rotates to connect the rotating shaft 6. A bearing is installed between the rotating shaft 6 and the connecting frame 5 to realize the rotation of the rotating shaft 6 relative to the connecting frame 5. The middle of the rotating shaft 6 The rotary tiller 7 is installed, and the motor 4 and the rotating shaft 6 are rotatably connected by a transmission group 8. The transmission group 8 is the structure of the existing ditcher, consisting of two transmission wheels and a transmission belt. The upper surface of the ring frame 1 is provided with a slot 9, and a steering component 10 is installed in the slot 9 for turning the handle 11 and the plow blade 13. The handle 11 is installed on the top of the steering component 10. In actual application, there is a control circuit connection between the handle 11 and the motor 4. The length of the circuit needs to be reserved to facilitate the turning of the handle 11. A connecting rod 12 is connected to the front side wall of the steering component 10, and the plow blade 13 is connected to the bottom of the connecting rod 12. The steering assembly 10 includes a movable plate 101 movably mounted on the upper surface of the ring frame 1. A movable block 102 is connected to the bottom of the movable plate 101. A through hole 103 is provided through the movable plate 101 on one side of the movable block 102. The position of the through hole 103 corresponds to the position of the positioning hole 15 on the annular edge 14. An L-shaped plate 104 is connected above the movable plate 101. A hinge 105 is connected between one side of the movable plate 101 and the L-shaped plate 104. Two positioning rods 106 are connected to the bottom of the L-shaped plate 104. The distance between the two positioning rods 106 is the same as the distance between adjacent positioning holes 15.

[0018] Specifically, the outer wall of the ring frame 1 is connected to an annular edge 14, and several positioning holes 15 are circumferentially and equidistantly arranged on the annular edge 14. Both the ring frame 1 and the annular edge 14 are circular. The ring frame 1 provides a basis for the movable plate 101 and the L-shaped plate 104 to make a circular path for turning.

[0019] Furthermore, the movable block 102 is an arc-shaped plate with a cross-section of T. The cross-sectional shape of the slot 9 corresponds to the movable block 102. The movable block 102 is inserted into the slot 9 and forms a sliding connection with the ring frame 1. By sliding the movable block 102 in the slot 9, the movable plate 101 is driven to switch between the frontmost position and the rearmost position of the ring frame 1.

[0020] Furthermore, the movable plate 101 is hinged to the L-shaped plate 104 via the hinge 105, enabling the L-shaped plate 104 to flip upward relative to the movable plate 101, facilitating the temporary disengagement of the positioning rod 106 from the positioning groove. The positioning rod 106 corresponds to the positions of the through hole 103 and the positioning hole 15. The positioning rod 106 passes through the through hole 103 and is movably inserted into the positioning hole 15. By inserting the positioning rod 106 into the positioning hole 15, the movable plate 101 is positioned, keeping the movable plate 101 relatively stationary with respect to the ring frame 1.

[0021] Furthermore, a dust cover 16 is connected to the bottom of the L-shaped plate 104. The dust cover 16 is an arc-shaped plate. The arc design of the dust cover 16 can block the soil caused by the rotation of the rotary tiller 7 over a large area, protecting the workers from the soil. The dust cover 16 is located at the bottom of the ring frame 1, and the top of the dust cover 16 is connected to the L-shaped plate 104. When the L-shaped plate 104 drives the handle 11 to turn, it drives the dust cover 16 to move synchronously, so that the position of the dust cover 16 can be adjusted according to the different working modes of the trencher.

[0022] The usage method of this embodiment is as follows: When the user is actually using the ditcher to plant soybeans in the field, firstly, the user uses the wheels on the front side of the plow blade 13 to move the ditcher to the designated position in the field. Then, the user holds the handle 11 to make the rotary tiller blade 7 contact the ground with the plow blade 13. Then, the user starts the diesel generator set 3, which uses diesel fuel to power the motor 4. The shaft end of the motor 4 drives the rotating shaft 6 to rotate via the transmission set 8. The rotating shaft 6 drives the rotary tiller blade 7 to rotate and dig furrows in the field. At the same time, the user holds the handle 11 to push the ditcher forward. The plow blade 13 digs furrows of a certain width in the tilled soil. During the furrowing process, the rotation of the rotary tiller blade 7 causes the soil to generate centrifugal force, and the soil is thrown up in the direction of the handle 11. The arc-shaped dust cover 16 effectively blocks the soil caused by the rotation of the rotary tiller blade 7. To protect workers from the mud, after one row of trenches is dug, move the trencher to one side, then push the handle 11 upwards. The handle 11 drives the L-shaped plate 104 to flip upwards relative to the movable plate 101 via the hinge 105, causing the L-shaped plate 104 to move the positioning rod 106 upwards and pull it out of the positioning hole 15. Then push the handle 11 horizontally, causing the movable plate 101 to slide the movable block 102 in the slot 9 until the movable plate 101 moves from the frontmost position of the ring frame 1 to the rearmost position. At this time, the user is at the rear of the ring frame 1. At the same time, the L-shaped plate 104 drives the plow blade 13 and the handle 11 to complete the rotation. Then lower the handle 11, so that the positioning rod 106 is reinserted into the positioning hole 15. Then switch the rotation direction of the motor 4 and continue trenching by pushing it behind the ring frame 1.

[0023] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
