Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and more specifically, it relates to an integrated agricultural ditching and fertilizing machine. Background Technology

[0002] A trenching and fertilizing machine is an agricultural machine mainly used to efficiently complete tasks such as trenching, fertilizing, and covering soil during the planting process. It replaces traditional manual fertilization with mechanized operation, greatly improving efficiency, and is especially suitable for large-scale planting scenarios such as field crops (such as corn and wheat), orchards, and vegetables.

[0003] Existing agricultural open-field fertilizer applicators typically apply fertilizer continuously during furrowing. However, because crops are planted at intervals, much of the fertilizer cannot be absorbed by the crops during continuous application, resulting in waste. To address this issue, existing technologies include machines capable of intermittent fertilization. However, these machines cannot adjust the fertilization interval according to the varying distances between crops, thus failing to achieve precise fertilization. Utility Model Content

[0004] This invention overcomes the problem in the prior art that the fertilization spacing cannot be adjusted according to the spacing of crops; it provides an integrated ditching and fertilization machine for agriculture, which can fertilize while ditching, and can adjust the fertilization spacing according to the spacing of different crops, thereby saving fertilizer and improving the utilization rate of fertilizer by crops.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: an agricultural ditching and fertilizing integrated machine, comprising: a frame and an interval fertilizing component, wherein a storage bin and several ditching components are provided on the frame; the ditching component includes a cutting wheel and a sliding shovel that fits against the end face of the cutting wheel; the sliding shovel and the cutting wheel cooperate to form a V-shaped opening;

[0006] The interval fertilization assembly includes a fertilization pipe corresponding to the V-shaped opening, the top of which is connected to the storage bin; several mounting holes are provided through the circumference of the cutting wheel, and bolt levers are threaded into the mounting holes; a valve stem perpendicular to its axis is provided inside the fertilization pipe, and the valve stem is perpendicular to the end face of the cutting wheel; a valve plate that mates with the inner wall of the fertilization pipe is provided on the valve stem; a return torsion spring that resets the valve plate is provided on the valve stem; an extension rod is provided at the end of the valve stem near the cutting wheel, and a vertical lever perpendicular to it is provided on the extension rod.

[0007] In this application, under normal conditions, the valve stem, under the action of the return torsion spring, causes the valve plate to engage with the inside of the fertilizer pipe, thereby sealing the fertilizer pipe. The fertilizer in the storage bin flows downward along the fertilizer pipe and is blocked by the valve plate. When the machine is in use, tires 11 are installed at both ends of the frame width. The frame is pulled by a power unit, such as a tractor. The cutting wheel inserts into the soil while rolling, and the cutting wheel cooperates with the skid to open a deep trench along the movement trajectory of the frame. During the rotation of the cutting wheel, the bolt lever on the cutting wheel also rotates under the drive of the cutting wheel. When the bolt lever contacts the vertical lever, the bolt lever drives the vertical lever to rotate around the extension rod. The extension rod drives the valve stem to rotate, and the valve stem rotates a certain angle against the elastic force of the return torsion spring. At this time, the fertilizer flows downward along the fertilizer pipe into the newly opened deep trench, realizing simultaneous trenching and fertilization. Because the bolt levers are spaced apart on the cutting wheel, as the wheel rolls, the bolt levers act sequentially on the vertical levers, thus achieving intermittent fertilization. Furthermore, since the cutting wheel has several mounting holes, different numbers of bolt levers can be installed to achieve different fertilization intervals, allowing the fertilization interval to be adjusted according to the spacing of different crops. This saves fertilizer and improves fertilizer utilization by crops.

[0008] Preferably, the frame is also equipped with a soil covering component corresponding to the V-shaped opening; the soil covering component includes two mud-turning rods, each equipped with a mud-turning plate, and the opening direction of the two mud-turning plates corresponds to the V-shaped opening.

[0009] The shovel can move along the deep trenches opened by the skid and the cutting wheel, and it can also cover the trenches with soil to improve fertilizer utilization.

[0010] Preferably, the side wall of the storage silo is provided with several discharge ports; each discharge port is provided with a discharge bracket; a discharge shaft is provided on the outer side wall of the storage silo, the discharge shaft is installed through several discharge brackets, and the discharge shaft can slide along the axial direction; a discharge rotating block and a limiting block corresponding to several discharge ports are provided on the discharge rotating shaft; several discharge grooves are provided in the circumferential direction of the discharge rotating block; a rolling wheel is also provided on the frame, a first sprocket is provided on the rolling wheel, a second sprocket is provided on the discharge rotating shaft, and the first sprocket and the second sprocket are driven by a chain.

[0011] The number of discharge ports and discharge brackets are the same as the number of trenching components. When the machine is in use, the rolling wheels contact the ground and rotate as the frame moves. The rolling wheels drive the first sprocket to rotate, which in turn drives the second sprocket via a chain, thus rotating the discharge shaft. The rotation of the discharge shaft causes the discharge block to rotate. When the discharge chute on the discharge block passes the discharge port, it carries the fertilizer out of the storage area. When the discharge chute rotates to face the fertilizer application pipe, waste material falls off the pipe under gravity, thus ensuring orderly feeding of the fertilizer application pipe during machine operation. Furthermore, by moving the discharge shaft axially, the limiting block can be aligned with the discharge port, thereby adjusting the discharge rate.

[0012] Preferably, the frame is also equipped with a locking shaft assembly for locking the discharge shaft. The locking shaft assembly includes a drive rod and a rotation fulcrum set on the side wall of the storage bin. The drive rod rotates around the rotation fulcrum. One end of the drive rod is rotatably connected to the discharge shaft, and the other end of the drive rod is provided with a guide shaft. An arc-shaped bracket is provided on the side wall of the storage bin, and an arc-shaped groove is provided in the arc-shaped bracket. The guide shaft slides in the arc-shaped groove, and a locking handle is rotatably connected to the guide shaft.

[0013] By loosening the locking handle, the guide shaft can slide within the arc groove, thereby controlling the movement of the discharge shaft in the axial direction. This allows control of the position of the limiting block corresponding to the discharge port, thus adjusting the discharge volume. When the limiting block completely blocks the discharge port, the discharge port cannot discharge material.

[0014] Preferably, tires are provided at both ends of the frame in the width direction.

[0015] Preferably, a bracket is provided on one side of the frame; a drag ring is provided at one end of the bracket, and side rods are provided on both sides of the other end, which are rotatably connected to the frame; a support rod is also provided on the frame, and a vibration damper is provided between the top of the support rod and the bracket.

[0016] Vibration dampers can reduce vibration between the power unit and the frame, allowing the frame to move more smoothly.

[0017] Preferably, two support rods are provided, and the tops of the two support rods are fixedly connected by a connecting plate. A fixing rod is provided on the side of the frame away from the carriage, and the top of the fixing rod is fixedly connected to the connecting plate.

[0018] The top of the fixing rod is fixedly connected to the connecting plate. This creates multiple triangular structures, making the overall structure more stable.

[0019] Preferably, the top of the storage silo is equipped with a silo cover.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] (1) Several mounting holes are provided on the cutting wheel, so that different numbers of bolts and levers can be set on the cutting wheel according to actual needs to achieve different spacing for fertilization. This allows the spacing of fertilization to be adjusted according to the spacing of different crops, thereby saving fertilizer and improving the utilization rate of fertilizer by crops.

[0022] (2) Set up a soil covering component so that the mud-turning plate can move along the deep trench opened by the sliding blade and the cutting wheel, and the mud-turning plate can cover the deep trench with soil to improve the utilization rate of fertilizer.

[0023] (3) By loosening the locking handle, the guide shaft can slide in the arc groove, thereby controlling the movement of the discharge shaft in the axial direction, thereby controlling the position of the limiting block and the discharge port, and thus adjusting the discharge amount of the discharge port. When the limiting block completely blocks the discharge port, the discharge port cannot discharge at this time. Attached Figure Description

[0036] The technical solution of this utility model will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings: Embodiment 1: Referring to Figures 1 to 6 As shown, an agricultural ditching and fertilizing integrated machine includes: a frame 1 and an intermittent fertilizing component 2. The frame 1 is provided with a storage bin 3 and several ditching components 4. The ditching component 4 includes a cutting wheel 41 and a sliding shovel 42 that fits against the end face of the cutting wheel 41. The sliding shovel 42 and the cutting wheel 41 cooperate to form a V-shaped opening. The top of the storage bin 3 is provided with a bin cover 31.

[0037] The intermittent fertilization assembly 2 includes a fertilization pipe 21 corresponding to the V-shaped opening, the top of which is connected to the storage bin 3; several mounting holes 411 are provided through the circumference of the cutting wheel 41, and bolt levers 22 are threaded into the mounting holes 411; a valve stem 23 perpendicular to its axis is provided inside the fertilization pipe 21, and the valve stem 23 is perpendicular to the end face of the cutting wheel 41; a valve plate 24 that mates with the inner wall of the fertilization pipe 21 is provided on the valve stem 23; a return torsion spring 27 that resets the valve plate 24 is provided on the valve stem 23; an extension rod 25 is provided at one end of the valve stem 23 near the cutting wheel 41, and a vertical lever 26 perpendicular to it is provided on the extension rod 25.

[0038] In this application, under normal conditions, the valve stem 23, under the action of the return torsion spring 27, causes the valve plate 24 to engage with the inside of the fertilizer pipe 21, thereby sealing the fertilizer pipe 21. The fertilizer in the storage bin 3 flows downward along the fertilizer pipe 21 and is stopped by the valve plate 24. When the machine is in use, tires 11 are provided at both ends of the frame 1 in the width direction. The frame 1 is pulled by a power unit, which can be a tractor or other equipment. As the cutting wheel 41 rolls, it inserts into the soil. Working in conjunction with the sliding shovel 42, the cutting wheel 41 creates a deep trench along the movement trajectory of the frame 1. During the rotation of the cutting wheel 41, the bolt lever 22 on it also rotates. When the bolt lever 22 contacts the vertical lever 26, it drives the vertical lever 26 to rotate around the extension rod 25. The extension rod 25 then drives the valve stem 23 to rotate, overcoming the elastic force of the return torsion spring 27. At this point, the fertilizer flows down the fertilizer pipe 21 into the newly created trench, achieving simultaneous trenching and fertilization. Because the bolt levers 22 are spaced apart on the cutting wheel 41, as the cutting wheel 41 rolls, the bolt levers 22 act sequentially on the vertical lever 26, thus achieving intermittent fertilization. Furthermore, since the cutting wheel 41 has several mounting holes 411, different numbers of bolt levers 22 can be installed on the cutting wheel 41 according to actual needs, enabling fertilization at different intervals. This allows for adjustment of the fertilization interval based on the spacing of different crops, thereby saving fertilizer and improving the utilization rate of fertilizer by crops. In addition, when the cutting wheel 41 rotates, the sliding shovel 42 is provided with a clearance groove to facilitate the passage of the bolt levers 22.

[0039] In one embodiment, the frame 1 is also provided with a soil covering component 5 corresponding to the V-shaped opening; the soil covering component 5 includes two mud-turning rods 51, and mud-turning plates 52 are provided on the two mud-turning rods 51, and the opening direction of the two mud-turning plates 52 corresponds to the V-shaped opening.

[0040] The mud-turning plate 52 can move along the deep trench opened by the sliding shovel 42 and the cutting wheel 41, and the mud-turning plate 52 can cover the deep trench with soil to improve the utilization rate of fertilizer.

[0041] In one embodiment, the side wall of the storage bin 3 is provided with a plurality of discharge ports 32; each discharge port 32 is provided with a discharge bracket 33; a discharge shaft 34 is provided on the outer side wall of the storage bin 3, the discharge shaft 34 is disposed through the plurality of discharge brackets 33, and the discharge shaft 34 can slide along the axial direction; a discharge rotating block 35 and a limiting block 36 corresponding to the plurality of discharge ports 32 are provided on the discharge shaft 34; a plurality of discharge grooves 351 are provided in the circumferential direction of the discharge rotating block 35; a rolling wheel 12 is also provided on the frame 1, a first sprocket 121 is provided on the rolling wheel 12, a second sprocket 122 is provided on the discharge shaft 34, and the first sprocket 121 and the second sprocket 122 are driven by a chain.

[0042] The number of discharge ports 32 and the number of discharge brackets 33 are the same as the number of trenching components 4. When the machine is in use, the rolling wheels 12 can contact the ground and rotate as the frame 1 moves. The rolling wheels 12 drive the first sprocket 121 to rotate, and then drive the second sprocket 122 to rotate through the chain, thereby driving the discharge shaft 34 to rotate. When the discharge shaft 34 rotates, it can drive the discharge block 35 to rotate. When the discharge trough 351 on the discharge block 35 passes the discharge port 32, it can carry out the fertilizer in the storage bin 3. When the discharge trough 351 rotates to face the fertilizer pipe 21, the fertilizer falls from the fertilizer pipe 21 under the action of gravity, thereby realizing the orderly feeding of fertilizer pipe 21 when the machine is working. In addition, by moving the discharge shaft 34 in the axial direction, the limiting block 36 can be aligned with the discharge port 32, thereby adjusting the discharge amount of the discharge port 32.

[0043] Therefore, in another embodiment, the frame 1 is also provided with a locking shaft assembly 6 for locking the discharge shaft 34. The locking shaft assembly 6 includes a drive rod 61 and a rotation fulcrum 62 provided on the side wall of the storage bin 3. The drive rod 61 rotates around the rotation fulcrum 62. One end of the drive rod 61 is rotatably connected to the discharge shaft 34, and the other end of the drive rod 61 is provided with a guide shaft 611. An arc-shaped bracket 63 is provided on the side wall of the storage bin 3. An arc-shaped groove 631 is provided in the arc-shaped bracket 63. The guide shaft 611 slides in the arc-shaped groove 631. A locking handle 64 is rotatably connected to the guide shaft 611. The locking handle 64 is threadedly connected to the guide shaft 611.

[0044] By loosening the locking handle 64, the guide shaft 611 can slide within the arc groove 631, thereby controlling the movement of the discharge shaft 34 in the axial direction. This allows control of the position of the limiting block 36 corresponding to the discharge port 32, thus adjusting the discharge amount of the discharge port 32. When the limiting block 36 completely blocks the discharge port 32, the discharge port 32 cannot discharge material.

[0045] In one embodiment, a bracket 13 is provided on one side of the frame 1; a drag ring 131 is provided at one end of the bracket 13, and side rods 14 are provided on both sides of the other end, and the side rods 14 are rotatably connected to the frame 1; a support rod 15 is also provided on the frame 1, and a shock absorber 16 is provided between the top of the support rod 15 and the bracket 13.

[0046] The vibration damper 16 can reduce the vibration between the power unit and the frame 1, so that the frame 1 can move more smoothly.

[0047] In this embodiment, two support rods 15 are provided, and the tops of the two support rods 15 are fixedly connected by a connecting plate 19 to form a triangular structure. A fixing rod 17 is provided on the side of the frame 1 away from the bracket 13, and the end of the fixing rod 17 is connected to the top of the support rod 15 by a diagonal brace 18. This results in the formation of multiple triangular structures, making the overall structure more stable.

[0048] The working principle of this application is as follows: Under normal conditions, the valve stem 23, under the action of the return torsion spring 27, causes the valve plate 24 to engage with the inside of the fertilizer pipe 21, thereby sealing the fertilizer pipe 21. The fertilizer in the storage bin 3 flows downward along the fertilizer pipe 21 and is stopped by the valve plate 24. When the machine is in use, tires 11 are installed at both ends of the frame 1 in the width direction. The frame 1 is pulled by a power unit, which can be a tractor or other equipment. As the cutting wheel 41 rolls, it inserts into the soil. Working in conjunction with the sliding shovel 42, the cutting wheel 41 creates a deep trench along the movement trajectory of the frame 1. During the rotation of the cutting wheel 41, the bolt lever 22 on it also rotates. When the bolt lever 22 contacts the vertical lever 26, it drives the vertical lever 26 to rotate around the extension rod 25. The extension rod 25 then drives the valve stem 23 to rotate, overcoming the elastic force of the return torsion spring 27. At this point, the fertilizer flows down the fertilizer pipe 21 into the newly created trench, achieving simultaneous trenching and fertilization. Because the bolt levers 22 are spaced apart on the cutting wheel 41, as the cutting wheel 41 rolls, the bolt levers 22 act sequentially on the vertical lever 26, thus achieving intermittent fertilization. Furthermore, since several mounting holes 411 are provided on the cutting wheel 41, different numbers of bolt levers 22 can be set on the cutting wheel 41 according to actual needs to achieve fertilization at different intervals. This allows the fertilization interval to be adjusted according to the spacing of different crops, thereby saving fertilizer and improving the utilization rate of fertilizer by crops.

[0049] The embodiments described above are merely preferred solutions of this utility model and are not intended to limit this utility model in any way. Other variations and modifications are possible without departing from the technical solutions described in the claims.
