Description

Technical Field

[0001] This invention relates to the field of ditching technology for tea planting, specifically a ditching machine suitable for tea planting on hillsides. Background Technology

[0002] Tea is mostly grown on hillsides, so ditching machines are needed to create ditches on the hillsides.

[0003] Traditional trenching machines often fail to completely break up and remove soil from the trench when cutting it. Some blades are poorly designed in terms of cutting angle, shape, or rotation speed, resulting in insufficient soil fragmentation. Large pieces of soil easily fall back into the trench under gravity, causing a large amount of soil to accumulate and reduce the intended trench depth. This makes it difficult to evenly distribute fertilizer around the tea plant roots after the soil has been backfilled. Furthermore, traditional trenching machines only perform trenching; after trenching, workers must manually add fertilizer, significantly extending the planting time. On hillsides, traditional trenching machines only break up the soil, often leaving behind weeds that cannot be removed. These weeds compete for soil nutrients, reducing the yield of tea plants.

[0004] Therefore, a trenching machine suitable for tea planting on hillsides is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a trenching machine suitable for tea planting on hillsides, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a ditching machine suitable for tea planting on hillsides, comprising a slope ditching vehicle, an electric disc ditcher installed at the bottom of the slope ditching vehicle, and a soil collection assembly at the bottom of the slope ditching vehicle. The soil collection assembly includes an electric telescopic rod fixedly connected to the lower surface of the slope ditching vehicle, a fixed column rotatably connected to the telescopic shaft end of the electric telescopic rod, a collection box fixedly connected to the end of the fixed column away from the electric telescopic rod, a cutter fixedly connected to the bottom of the collection box, a rotating column rotatably connected through the inner wall of the collection box, an electric roller rotatably connected through the inner wall of the collection box, and a conveyor belt drivingly connecting the electric roller and the rotating column.

[0007] Furthermore, the bottom of the slope trenching vehicle is equipped with a soil transfer assembly, which includes a rotating column three rotatably connected to the bottom of the slope trenching vehicle, a conveyor belt two drivingly connected between the electric roller and the rotating column three, a rotating column four rotatably connected to the bottom of the slope trenching vehicle, a conveyor chain drivingly connected between the rotating column four and the rotating column three, multiple material boxes fixedly connected to the side wall of the conveyor chain, and a transfer box fixedly connected through the bottom of the slope trenching vehicle, with an inclined block installed inside the transfer box.

[0008] Furthermore, the bottom of the slope ditching vehicle is equipped with a fertilization component, which includes a first bevel gear fixedly connected to the rotating shaft end of the electric disc ditcher, a second bevel gear rotatably connected to the side wall of the slope ditching vehicle, a fixed base plate fixedly connected to the bottom of the slope ditching vehicle, a connecting column rotatably connected to the top of the fixed base plate, and a synchronous belt drivingly connecting the second bevel gear and the connecting column rotatably.

[0009] Furthermore, a rotating frame is fixedly connected to the end of the connecting column one that is away from the synchronous belt. A rectangular hole is opened at the eccentric part of the rotating frame. A connecting column two is rotatably connected to the top of the fixed base plate. A connecting frame is rotatably connected to the outer side of the connecting column two. A throwing cylinder is fixedly connected to the top of the connecting column two. A throwing pipe is fixedly connected to the outer side of the throwing cylinder. A storage box is fixedly connected to the side wall of the earth slope trenching vehicle. A discharge pipe is fixedly connected to the bottom of the storage box.

[0010] Furthermore, the inner wall of the ditching vehicle is rotatably connected to both ends of the electric roller, the cutter is set as an incline, and the cutter is made of stainless steel.

[0011] Furthermore, the width of the cutter is adapted to the width of the conveyor belt, and the width of the collection box is adapted to the width of the electric disc trencher.

[0012] Furthermore, the multiple material carriers are arranged in a linear array along the side wall of the conveyor chain, and the transfer box is located on the movement path of the multiple material carriers, which are located on the movement path of the first conveyor belt.

[0013] Furthermore, the inclined block is a double slope with the center of the transfer box as the apex on both sides.

[0014] Furthermore, the first bevel gear meshes with the second bevel gear.

[0015] Furthermore, the rectangular hole is inserted into the end of the connecting frame away from the throwing cylinder, and the size of the throwing cylinder is adapted to the size of the discharge pipe.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: the residual soil collection component and the residual soil transfer device prevent soil from returning to the ditch during the continuous digging of the ditch by the electric disc ditcher. The transfer box transports the broken soil to a place away from the ditch, ensuring the stability of the ditch wall during the ditching process, making the shape of the ditch more regular and the ditch depth consistent. At the same time, there is no need to frequently stop to clean up the residual soil, so the slope ditching vehicle can work continuously, improving the work efficiency of hillside tea planting. It can also turn over the residual soil in the ditch and remove weeds in the ditch to both sides of the ditch using inclined blocks.

[0017] The fertilization component allows for simultaneous ditching and fertilization using an electric disc ditcher, eliminating the need for separate operations and reducing overall work time, thus improving the efficiency of hillside tea plantation.

[0018] The continuous oscillation of the feeding pipe allows fertilizer to be continuously applied to the ditches in an S-shaped trajectory, ensuring even distribution over a large area. This avoids the uneven fertilization caused by factors such as technique, force, and walking speed in traditional manual application, resulting in a relatively balanced supply of nutrients to the soil in the ditches.

[0019] The electric telescopic rod allows the collection box to be placed at the bottom of the ditch during slope dredging and to be retracted when slope dredging is not needed, thus preventing wear and tear on the collection box from the slope dredging vehicle when slope dredging is not being carried out.

[0020] The cutting blades effectively remove the remaining grass roots in the ditches, thus reducing competition from weeds for soil nutrients, water, and space, and improving the survival rate of tea plants. Attached Figure Description

[0043] The working principle of the above implementation is as follows:

[0044] The initialization steps are as follows: When the earth slope trenching vehicle 1 has not started trenching the hillside, the earth slope trenching vehicle 1 is not equipped with the electric disc trencher 2, thus avoiding damage to the ground during normal driving. The electric telescopic rod 3 is in the retracted state, so the electric telescopic rod 3 drives the collection box 5 to swing vertically upward with the connection between the electric roller 8 as the axis. Thus, the end of the collection box 5 near the electric telescopic rod 3 is no longer lower than the chassis of the earth slope trenching vehicle 1, avoiding the situation where the collection box 5 is worn when the earth slope trenching vehicle 1 is driving normally.

[0045] The operation steps are as follows:

[0046] The working steps of the excess soil collection component are as follows:

[0047] When the construction workers drive the earth slope trenching vehicle 1 to a suitable hillside for tea planting, they install the electric disc trencher 2 at the bottom front of the earth slope trenching vehicle 1. Simultaneously, the earth slope trenching vehicle 1 begins to move along the area of ​​the hillside that needs trenching. The electric disc trencher 2 starts rotating, scooping out trenches from the hillside soil. Although the electric disc trencher 2 rotates at high speed to scoop out trenches, soil still accumulates on both sides of the trench and falls into it. At this time, the electric telescopic rod 3 is energized and pushes the collection box 5, causing the connection between the collection box 5 and the electric roller 8 to swing vertically downwards. When the side of the collection box 5 close to the electric telescopic rod 3 is against the trench, the cutter 6 is also close to the trench. At this time, the cutter 6, along with the movement of the earth slope trenching vehicle 1, continuously collects the broken soil that has fallen into the trench, moving along the slope of the cutter 6 towards the conveyor belt 9. The electric roller 8 is energized and starts rotating clockwise, and through friction, it rotates the conveyor belt 9 away from the cutter 6, thus continuously collecting the broken soil.

[0048] The working steps of the excess soil transfer component are as follows:

[0049] As described above, after the electric roller 8 is powered on, it rotates clockwise and drives the conveyor belt 9 through friction. When the soil on the conveyor belt reaches the highest point of the conveyor belt, it will fall off due to its own weight. At this time, the continuous rotation of the electric roller 8 causes the rotating column 10 to rotate synchronously through the conveyor belt 11. The clockwise rotation of the rotating column 10 continuously drives the conveyor chain 12 to rotate clockwise. The conveyor chain 12 drives the rotating column 14 to rotate, so the loading box 13 continuously loads the soil falling from the top of the conveyor belt 9. When the loading box 13 loaded with soil reaches the top of the transfer box 15, the downward trend of the loading box 13 causes the soil in the loading box 13 to fall into the inner cavity of the transfer box 15 due to its own gravity. At this time, the soil rolls down the slope of the inclined block 16 until it rolls to a distance away from the sides of the ditch, thereby reducing the amount of soil in the ditch and preventing the soil from burying the original depth of the ditch.

[0050] The soil collection and transfer components prevent soil from returning to the trenches during the continuous digging process of the electric disc trencher 2. The transfer box 15 transports the broken soil away from the trenches, ensuring the stability of the trench walls during the trenching process, making the trench shape more regular, and maintaining a consistent trench depth. At the same time, there is no need to frequently stop to clean up the backfilled soil, so that the slope trencher 1 can continue to operate, improving the work efficiency of hillside tea planting. It can also turn over the soil in the trenches and remove weeds in the trenches to both sides of the trenches through the inclined blocks 16.

[0051] The electric telescopic rod 3 allows the collection box 5 to be placed at the bottom of the ditch during the process of ditching on the hillside, and can be retracted when ditching is not required, thus avoiding wear and tear on the collection box 5 when the ditching vehicle 1 is not performing ditching.

[0052] The cutting blade 6 is designed to remove the remaining grass roots in the ditch. Removing the grass roots can effectively reduce the competition of weeds for soil nutrients, water and space, and improve the survival rate of tea plants.

[0053] The operating steps of the fertilizer application component are as follows:

[0054] During the rotation of the electric disc trencher 2, the electric disc trencher 2 drives the first bevel gear 17 to rotate synchronously. The rotation of the first bevel gear 17 causes the meshing second bevel gear 18 to rotate. The second bevel gear 18 causes the connecting column 20 to rotate via the synchronous belt 21. The rotation of the connecting column 20 causes the rotating frame 22 with the same center to rotate synchronously. Because of the rectangular hole 23 eccentrically opened inside the rotating frame 22, and because the end of the connecting frame 25 away from the throwing cylinder 26 is inserted into the rectangular hole 23, when the rectangular hole 23 rotates and changes position, the rectangular hole 23 causes the connecting frame 25 to swing up and down vertically with the connection point between the connecting frame 25 and the second connecting column 24 as the center. In the horizontal direction, the connecting frame 25 drives the two protrusions to swing back and forth within the range of the diameter of the rotating frame 22. At the same time, the back-and-forth swing of the two protrusions causes the second connecting column 24 to swing back and forth with the connection point between the second connecting column 24 and the fixed base plate 1. The connection point 9 is a reciprocating shaft. The reciprocating rotation of the connecting column 24 causes the throwing cylinder 26 to rotate synchronously, and the electric valve of the discharge pipe 29 is opened. Thus, the fertilizer in the storage box 28 enters the throwing cylinder 26 through the discharge pipe 29 and is affected by gravity. Therefore, the reciprocating swing of the throwing cylinder 26 throws the fertilizer in its inner cavity out through the throwing pipe 27 by inertia. When the fertilizer is thrown out of the throwing pipe 27, as mentioned above, this process occurs during the movement of the earth slope trenching vehicle 1. During the continuous movement of the earth slope trenching vehicle 1, the electric disc trencher 2 has already dug trenches on the earth slope. Therefore, the fertilizer is again affected by gravity and falls into the trench with a parabolic trajectory. At this time, the broken soil in the trench has been cleared by the above steps, so that the fertilizer can reach the deepest part of the trench. At the same time, the continuous S-shaped throwing can make the fertilizer evenly distributed inside the trench.

[0055] The fertilization component allows for simultaneous ditching and fertilizer application using the electric disc ditcher 2, eliminating the need for separate ditching and fertilization operations, reducing overall operation time, and improving the efficiency of hillside tea planting.

[0056] The continuous oscillation of the throwing pipe 27 allows fertilizer to be continuously thrown into the ditch along an S-shaped trajectory, ensuring uniform distribution of fertilizer over a large area. This avoids the uneven fertilization caused by factors such as technique, force, and walking speed during traditional manual spreading, resulting in a relatively balanced supply of nutrients to the soil in the ditch.
