Description

Technical Field

[0001] This invention relates to the field of grassland ecological restoration technology, specifically to a grass seed spreading device for ecological restoration in mining areas. Background Technology

[0002] Mining is very frequent, and if the mined areas are not repaired in time, they will seriously affect the health and living environment of the surrounding residents. To address this, many researchers have developed improvement measures. One such improvement plan involves spreading materials to allow green grass and plants to grow rapidly in the mined areas. This not only prevents soil erosion but also absorbs various toxic gases emitted by the quarry.

[0003] Among related technologies, material spreading is inefficient and detrimental to the restoration of the mining area's ecology. Summary of the Invention

[0004] This invention is based on the inventor's discoveries and understanding of the following facts and problems:

[0005] Patent CN217037910U proposes a grass seed sowing device for grassland ecological restoration. The device uses a cylinder in the sowing mechanism to drive a second through-plate to reciprocate, causing multiple openings of the second through-plate to repeatedly connect with multiple openings of the first through-plate. This allows the material placed inside the tank to fall evenly and be transferred into the soil loosened by plowing and harrowing. However, this solution is not entirely suitable for mining areas. Due to excessive mining, the ground in these areas is more uneven than grassland and contains more gravel. In the case of drilling holes in the mining area, the sowing position may not yet reach the pre-drilled location. During travel, the device may shift due to road bumps, causing the discharge position to misalign with the drilling position. This results in the grass seeds not being delivered into the pre-drilled holes and falling outside. The abundant gravel outside also hinders the rooting and growth of the grass seeds, which is detrimental to the ecological restoration of the mining area.

[0006] The present invention aims to at least partially solve one of the technical problems in the related art.

[0007] Therefore, embodiments of the present invention propose a grass seed spreading device for ecological restoration in mining areas with high material spreading efficiency and the ability to send materials into pre-drilled holes.

[0008] According to an embodiment of the present invention, a grass seed spreading device for ecological restoration in mining areas includes: a vehicle body, the vehicle body including a body and a frame, the body being mounted on the frame; a storage box mounted on the vehicle body, the storage box having a discharge hole extending vertically through the bottom of the storage box for storing materials; and a drill rod assembly mounted below the vehicle body, the drill rod assembly and the storage box being spaced apart along the length of the vehicle body, the drill rod assembly having a through hole extending vertically through the drill rod assembly, the drill rod assembly being movable vertically relative to the vehicle body, and the drill rod assembly being movable along the length of the vehicle body relative to the vehicle body. The spreading device has a first working state and a second working state. In the first working state, the drill rod assembly moves downward so that it is inserted into the ground of the mining area to drill a hole in the ground. In the second working state, the vehicle body moves the storage box above the drill rod assembly so that the discharge hole and the through hole communicate so that the material flows through the drill rod assembly into the hole in the ground of the mining area.

[0009] The grass seed spreading device for ecological restoration in mining areas according to this invention includes a vehicle body, a storage box, and a drill rod assembly. This ensures that the grass seeds in the storage box are delivered deep into the hole, thereby completing the seeding work on the mining area ground and improving the efficiency of grass seed spreading.

[0010] In some embodiments, the drill rod assembly includes a mounting plate and a drill rod. The mounting plate is located below the vehicle body and is movable relative to the vehicle body in a vertical direction and also movable relative to the vehicle body along the length of the vehicle body. The drill rod is located below the mounting plate and is rotatable relative to the mounting plate in a vertical direction. The through hole is formed in the drill rod.

[0011] In some embodiments, the drill pipe assembly further includes a telescopic assembly, which is disposed on the vehicle body and the piston rod of the telescopic assembly is connected to the mounting plate, so that the telescopic assembly can move the mounting plate in the vertical direction and the telescopic assembly can move relative to the vehicle body along the length direction of the vehicle body.

[0012] In some embodiments, there are multiple drill rods, which are spaced apart on the mounting plate along the width direction of the vehicle body. There are multiple discharge holes, which are all located at the bottom of the storage box and spaced apart along the width direction of the vehicle body. In the second working state, the through holes of the multiple drill rods are connected to the multiple discharge holes one by one.

[0013] In some embodiments, the drill pipe assembly further includes a plurality of sequentially meshing gears and a first drive member, wherein at least one of the gears is provided on the drill pipe, and the first drive member is connected to the drill pipe so that the first drive member drives the drill pipe to rotate.

[0014] In some embodiments, the seed spreading device for ecological restoration in mining areas further includes an elastic element disposed between the drill rod assembly and the vehicle body, with both ends of the elastic element connected to the drill rod assembly and the vehicle body respectively. In the second working state, the elastic element has an elastic force that drives the drill rod assembly away from the storage box along the length direction of the vehicle body. The spreading device also has a third working state in which the drill rod assembly moves upward so that the drill rod assembly separates from the ground in the mining area, and the drill rod assembly moves towards and away from the storage box under the action of the elastic force of the elastic element.

[0015] In some embodiments, the grass seed spreading device for ecological restoration in mining areas further includes a gate, which is disposed inside the storage box and movable relative to the storage box in a first position and a second position. In the first position, the gate is disposed on the discharge hole so that the gate blocks the discharge hole. In the second position, the gate and the discharge hole are spaced apart in the length direction of the housing so that the material flows out through the discharge hole.

[0016] In some embodiments, the grass seed spreading device for ecological restoration of mining areas further includes a second driving member, which is disposed in the storage box and connected to the gate, so that the second driving member drives the gate to move between the first position and the second position.

[0017] In some embodiments, the vehicle body is provided with a groove that runs vertically through the vehicle body and extends along the length of the vehicle body. The drill rod assembly also includes a slide plate that is movably disposed within the groove. The slide plate is connected to the telescopic assembly so that the telescopic assembly can slide on the vehicle body via the groove and the slide plate.

[0018] In some embodiments, the vehicle body is provided with a mounting hole that penetrates the vehicle body in a vertical direction. The dispensing device further includes a plurality of positioning members, which are spaced apart circumferentially on the inner circumferential surface of the mounting hole. The positioning members are movable relative to the mounting hole in an inward or outward direction. The storage box passes through the mounting hole and the plurality of positioning members abut against the outer circumferential surface of the storage box. Attached Figure Description

[0030] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0031] The following description, with reference to the accompanying drawings, describes a grass seed spreading device for ecological restoration in mining areas according to an embodiment of the present invention.

[0032] like Figure 1-6 As shown, the grass seed spreading device for ecological restoration of mining areas according to an embodiment of the present invention includes a vehicle body 1, a storage box 2, and a drill rod assembly 3.

[0033] The vehicle body 1 includes a body 11 and a frame 12, with the body 11 mounted on the frame 12. Specifically, as shown... Figure 1-3As shown, the vehicle body 11 is a rectangular plate extending in the left and right direction and is fixedly installed on the frame 12. The frame 12 is equipped with a moving wheel 14, and the right end of the frame 12 is fixedly installed with a push frame 13, so that the vehicle body 1 can be pushed to move in the mining area through the push frame 13.

[0034] Storage box 2 is mounted on the vehicle body 11. The bottom of storage box 2 has a discharge hole 21 extending vertically through it. Storage box 2 is used to store materials. Specifically, as shown... Figure 1-3 As shown, the storage box 2 stores materials (e.g., grass seeds). The storage box 2 is fixedly installed on the vehicle body 11 and the bottom of the storage box 2 passes through the vehicle body 11. The lower end face of the storage box 2 is provided with a discharge hole 21 that passes through the storage box 2, so that the materials can flow out of the storage box 2 through the discharge hole 21.

[0035] The drill rod assembly 3 is located below the vehicle body 11, and the drill rod assembly 3 and the storage box 2 are along the length of the vehicle body 1 (e.g., Figure 1 The drill rod assembly 3 is arranged at intervals in the left-right direction (as shown). It has a through hole 321 extending vertically through the drill rod assembly 3. The drill rod assembly 3 is movable relative to the vehicle body 1 in the vertical direction and also movable relative to the vehicle body 1 along its length. The spreading device 100 has a first working state and a second working state. In the first working state, the drill rod assembly 3 moves downwards to be inserted into the mine surface to drill holes. In the second working state, the vehicle body 1 moves the storage box 2 above the drill rod assembly 3, so that the discharge hole 21 and the through hole 321 connect to allow material to flow through the drill rod assembly 3 into the holes in the mine surface.

[0036] Specifically, such as Figure 1-3 As shown, the drill rod assembly 3 is located below the vehicle body 11 and to the left of the storage box 2, so that the drill rod assembly 3, the storage box 2 and the push rod are arranged alternately in the left and right directions. The drill rod assembly 3 can move in the up and down direction and the left and right direction. The drill rod assembly 3 is provided with a through hole 321 that runs through the drill rod assembly 3 in the up and down direction. In the first working state, the drill rod assembly 3 moves downward, so that the drill rod assembly 3 is inserted into the ground of the mining area to drill a hole in the ground of the mining area. In the second working state, the vehicle body 1 continues to move forward. At this time, the drill rod assembly 3 is inserted into the ground of the mining area, so that the drill rod assembly 3 no longer moves with the vehicle body 1. When the vehicle body 1 moves the storage box 2 to above the drill rod assembly 3, and the discharge hole 21 of the storage box 2 and the through hole 321 of the drill rod assembly 3 are opposite to each other in the up and down direction and are connected, so that the material is sown in the hole drilled by the drill rod assembly 3 through the discharge hole 21 and the through hole 321.

[0037] The grass seed spreading device 100 for ecological restoration in mining areas according to this invention includes a vehicle body 1, a storage box 2, and a drill rod assembly 3. The drill rod assembly 3 drills holes in the mining area ground. After drilling, the drill rod assembly 3 is not retracted, but instead pushes the vehicle body 1 to move until the discharge hole 21 moves above the drill rod assembly 3, connecting the discharge hole 21 and the through hole 321. Material is then fed into the depth of the hole through the through hole 321, thus completing the seeding work on the mining area ground. Compared with related technologies, this effectively solves the problem of device misalignment due to road bumps, causing the material discharge position to be misaligned with the drilling position. It ensures that the material is fed into the pre-drilled hole, preventing material from flowing outside the drill hole, ensuring material growth, and reducing material utilization efficiency.

[0038] In some embodiments, the drill rod assembly 3 includes a mounting plate 31 and a drill rod 32. The mounting plate 31 is located below the vehicle body 11 and is movable relative to the vehicle body 1 in the vertical direction. The mounting plate 31 is also movable relative to the vehicle body 1 along its length. The drill rod 32 is located below the mounting plate 31 and is rotatable relative to the mounting plate 31 in the vertical direction. A through hole 321 is formed within the drill rod 32. Specifically, as... Figure 1-3 and Figure 6 As shown, the mounting plate 31 is a horizontal plate extending forward and backward. The drill rod 32 extends in the vertical direction and its upper end is fixedly mounted on the mounting plate 31. The drill rod 32 is provided with a through hole 321 that passes through the drill rod 32 in the vertical direction. The mounting plate 31 is located below the vehicle body 11 and can move in the left-right and forward-backward directions, so that the mounting plate 31 drives the drill rod 32 to move below the vehicle body 11.

[0039] In some embodiments, the drill pipe assembly 3 further includes a telescopic assembly 33, which is mounted on the vehicle body 1 and whose piston rod is connected to the mounting plate 31, so that the telescopic assembly 33 can move the mounting plate 31 in the vertical direction, and the telescopic assembly 33 can move relative to the vehicle body 1 along the length direction of the vehicle body 1. Specifically, as Figure 1-3 As shown, the telescopic component 33 is an electric push rod. The telescopic component 33 is mounted on the vehicle body 11 and can move in the left and right directions on the vehicle body 11. The piston rod of the telescopic component 33 is fixedly connected to the mounting plate 31, so that the mounting plate 31 is mounted on the vehicle body 11 through the telescopic rod. The telescopic component 33 can perform telescopic movement, thereby driving the connecting plate 81 and the drill rod 32 to move in the up and down directions. The telescopic component 33 provides a power base for the mounting plate 31.

[0040] In some embodiments, there are multiple drill rods 32, and the multiple drill rods 32 are arranged along the width direction of the vehicle body 1 (e.g., Figure 1The discharge holes 21 are spaced apart on the mounting plate 31 in the front-to-back direction (as shown). Multiple discharge holes 21 are located at the bottom of the storage box 2 and spaced apart along the width of the vehicle body 1. In the second working state, the through holes 321 of the multiple drill rods 32 are connected one-to-one with the multiple discharge holes 21. Specifically, as shown... Figure 1-3 As shown, there can be multiple drill rods 32 and discharge holes 21, and the number of drill rods 32 and discharge holes 21 is equal. Multiple drill rods 32 are fixedly installed on the mounting plate 31 at intervals along the front-back direction, and multiple discharge holes 21 are arranged at intervals along the front-back direction at the bottom of the storage box 2. In the second working state, when the storage box 2 moves with the vehicle body 1 to above the drill rod assembly 3, the upper ends of the through holes 321 of the multiple drill rods 32 are connected to the multiple discharge holes 21 one by one, so that the material in the storage box 2 can be sown through the cooperation of multiple discharge holes 21 and multiple drill rods 32, thereby improving the efficiency of material sowing.

[0041] In some embodiments, the drill pipe assembly 3 further includes a plurality of sequentially meshing gears 34 and a first drive member 35. At least one gear 34 is provided on the drill pipe 32, and the first drive member 35 is connected to the drill pipe 32 so that the first drive member 35 drives the drill pipe 32 to rotate. Specifically, as... Figure 6 As shown, the gear 34 can be a spur gear 34, and the number of gears 34 can be multiple and equal to the number of drill rods 32. Each drill rod 32 is provided with a gear 34, and the gears 34 on two adjacent drill rods 32 mesh with each other. The first driving component 35 is a motor and is fixedly mounted on the mounting plate 31. The motor is connected to one of the multiple gears 34, thereby driving the multiple gears 34 to rotate, which in turn drives the drill rod 32 to rotate, thereby improving the drilling efficiency of the drill rod 32.

[0042] In some embodiments, the grass seed spreading device 100 for ecological restoration in mining areas further includes a gate 6. The gate 6 is disposed inside the storage tank 2 and is movable relative to the storage tank 2 in a first position and a second position. In the first position, the gate 6 is disposed on the discharge hole 21 so that the gate 6 blocks the discharge hole 21. In the second position, the gate 6 and the discharge hole 21 are spaced apart in the length direction of the housing so that the material flows out through the discharge hole 21. Specifically, as Figure 4 As shown, there can be two gates 6. Both gates 6 are located inside the storage box 2 and at the bottom of the storage box 2. The two gates 6 can move in the left and right direction inside the storage box 2. In the first working state, the gates 6 are in the first position, and the two gates 6 are close to each other to cover the discharge hole 21, thereby blocking the discharge hole 21 and preventing the material from flowing out of the discharge hole 21. In the second working state, the gates 6 are in the second position, and the two gates 6 are far apart from each other, so that the gates 6 no longer block and cover the discharge hole 21, thereby allowing the material to flow out through the discharge hole 21.

[0043] In some embodiments, the grass seed spreading device 100 for ecological restoration in mining areas further includes a second driving member 7, which is disposed in the storage box 2 and connected to the gate 6, so that the second driving member 7 drives the gate 6 to move between a first position and a second position. Specifically, as Figure 4 As shown, the second driving component 7 can be an electric push rod. There are two second driving components 7, and both are fixed inside the storage box 2. The two electric push rods are respectively connected to the two gates 6, so that the two gates 6 can be controlled to move inside the storage box 2 through the two driving components.

[0044] In some embodiments, the vehicle body 11 is provided with a groove 111 extending through the vehicle body 11 in a vertical direction. The groove 111 extends along the length direction of the vehicle body 1. The drill rod assembly 3 also includes a slide plate 8, which is movably disposed within the groove 111. The slide plate 8 is connected to the telescopic assembly 33 so that the telescopic assembly 33 can slide on the vehicle body 1 via the groove 111 and the slide plate 8. Specifically, as Figure 1-3 As shown, there are two slides 111 and two slide plates 8. The two slides 111 are formed on the front and rear sides of the vehicle body 11. The slides 111 penetrate the vehicle body 11 in the vertical direction and extend in the horizontal direction. The two slide plates 8 are slidably disposed in the two slides 111. One side of the slide plate 8 is connected to the telescopic component 33. The telescopic end of the telescopic component 33 passes through the slide 111 and is connected to the mounting plate 31, so that the mounting plate 31 is connected to the slide plate 8 through the telescopic component 33. Thus, in the second working state, the vehicle body 1 and the drill rod assembly 3 can move relative to each other through the cooperation of the slide plate 8 and the slide 111.

[0045] In some embodiments, the grass seed spreading device 100 for ecological restoration in mining areas further includes an elastic element 4. The elastic element 4 is disposed between the drill rod assembly 3 and the vehicle body 1, and its two ends are respectively connected to the drill rod assembly 3 and the vehicle body 1. In a second working state, the elastic element 4 has an elastic force that drives the drill rod assembly 3 away from the storage box 2 along the length direction of the vehicle body 1. The spreading device 100 also has a third working state in which the drill rod assembly 3 moves upward so that the drill rod assembly 3 separates from the surface of the mining area. Under the action of the elastic force of the elastic element 4, the drill rod assembly 3 moves in a direction away from the storage box 2. Specifically, as Figure 2As shown, the elastic element 4 is located between the right end of the slide plate 8 and the right end of the frame 12, and both ends of the elastic element 4 are connected to the right end of the slide plate 8 and the right end of the frame 12, respectively. In the first working state, the elastic element 4 can be at its original length. In the second working state, when the drill rod 32 is inserted into the ground of the mining area, the drill rod 32 will be positioned and will not move with the vehicle body 1. As the vehicle body 1 moves, the elastic element 4 will be compressed so that the elastic element 4 has an elastic force to drive the drill rod assembly 3 to move to the left. When the through hole 321 of the drill rod 32 and the discharge hole 21 are connected and the material is sown, the grass seed sowing device 100 for ecological restoration of the mining area is in the third working state. The drill rod 32 moves upward under the action of the telescopic component 33, so that the drill rod 32 is separated from the ground of the mining area, thereby causing the drill rod assembly 3 to move to the left under the action of the elastic element 4, so that the drill rod assembly 3 is reset.

[0046] In some embodiments, such as Figure 2 As shown, the grass seed spreading device 100 for ecological restoration in mining areas also includes a connecting plate 81 and two guide rods 5. The right ends of the two sliding plates 8 are connected to a connecting plate 81. The two guide rods 5 are respectively located inside the front and rear sides of the vehicle body 11. There are two elastic elements 4, which are respectively inserted through the two guide rods 5. The elastic elements 4 are located between the connecting plate 81 and the right end face of the vehicle body 11 and are respectively connected to the right end face of the connecting plate 81 and the right end face of the vehicle body 11. At this time, the elastic element 4 is a tension spring. When the vehicle body 1 and the drill rod assembly 3 slide relative to each other in the left and right direction, the connecting plate 81 moves to the right and stretches the elastic element 4 so that the elastic element 4 has elastic force. Thus, the guide rods 5 guide and limit the movement of the sliding plates 8, so that they can only move horizontally along the slide groove 111. The guide rods 5 also provide an installation base for the elastic element 4, making the grass seed spreading device 100 for ecological restoration in mining areas more reasonably set up.

[0047] In some embodiments, the vehicle body 11 is provided with a mounting hole 112 extending through the vehicle body 11 in a vertical direction. The dispensing device 100 further includes a plurality of positioning members 113, which are spaced apart circumferentially on the inner circumferential surface of the mounting hole 112. The positioning members 113 are movable relative to the mounting hole 112 in an inward or outward direction. The storage box 2 passes through the mounting hole 112, and the plurality of positioning members 113 abut against the outer circumferential surface of the storage box 2. Specifically, as shown in the figure... Figure 5 As shown, the left end of the vehicle body 11 is provided with a rectangular mounting hole 112 that runs through the vehicle body 11 in the vertical direction, and four positioning elements 113 (such as...) are provided on the inner circumferential surface of the mounting hole 112. Figure 5As shown in the four figures, an electric telescopic rod 114 is rotatably mounted on the inner wall of the four corners of the mounting hole 112 via a universal joint. The positioning member 113 is an angle iron and is located at the other end of the electric telescopic rod 114. The storage box 2 passes through the mounting hole 112 and the positioning member 113 abuts against the outer peripheral surface of the storage box 2. Thus, the electric telescopic rod 114 can extend and retract to drive the positioning member 113 to move in the inward and outward directions. The storage box 2 can be engaged in the mounting hole 112 by the positioning member 113. When the vehicle body 1 moves and bumps, the positioning member 113 limits the storage box 2, keeping the storage box 2 upright and preventing the storage box 2 from interfering with the movement of the vehicle body 11.

[0048] The following is based on the appendix Figures 1 to 6 A schematic diagram of the structure of the grass seed spreading device 100 for ecological restoration of mining areas according to an embodiment of the present invention is described in detail.

[0049] The grass seed spreading device 100 for ecological restoration in mining areas includes a vehicle body 11 and a frame 12. The frame 12 has four casters 14 at its bottom corners, and a pusher 13 is fixed to the right end of the frame 12. The vehicle body 11 has mounting holes 112, and a storage box 2 is installed inside each mounting hole 112. Discharge holes 21 are equidistantly arranged at the bottom of the storage box 2. A drill rod assembly 3 is located at the bottom left end of the vehicle body 11. The drill rod assembly 3 includes a mounting plate 31, and multiple drill rods 32 are equidistantly mounted on the surface of the mounting plate 31 via bearings. Each drill rod 32 has a through hole 321 inside, and the position of the drill rod 32 is relative to the discharge holes 2. On the left and right sides of the vehicle body 11, symmetrical grooves 111 are provided on both sides of the storage box 2. A sliding plate 8 is slidably inserted into the groove 111, and the mounting plate 31 is set at the bottom of the sliding plate 8. When using the device, grass seeds are put into the storage box 2 and the device is pushed to move. The drill rod 32 of the drill rod assembly 3 is used to drill holes in the mining area. Then the drill rod assembly 3 remains stationary and the device is pushed to move until the discharge hole 21 corresponds to the through hole 321 of the drill rod 32. The grass seeds are then sent into the hole through the through hole 321. The drill rod assembly 3 is then retracted to start the next set of drilling and sowing.

[0050] The drill rod assembly 3 also includes a telescopic assembly 33. The telescopic assembly 33 is fixed on the top surface of the slide plate 8 opposite to the mounting plate 31, and the extended end of the telescopic assembly 33 is fixed to both sides of the mounting plate 31. A gear 34 is fixedly sleeved on the upper surface of the drill rod 32, and adjacent gears 34 are meshed. A first drive member 35 is fixed on the surface of the mounting plate 31, and a gear 34 is fixed at the output end of the first drive member 35. The gear 34 meshes with one of the gears 34. A guide rod 5 is fixed to the outside of the slide plate 8 through the mounting plate 31, and the guide rod 5 is slidably inserted into the inside of both sides of the vehicle body 11. An elastic member 4 is sleeved on the surface of the guide rod 5, and the elastic member... 4. Both ends are fixed to the slide plate 8 and the body 11. The telescopic component 33 drives the mounting plate 31 to descend. The first drive component 35 is activated to drive the gear 34 to mesh with the gear 34. The drill rod 32 rotates and drills into the ground. It maintains its position and continues to push the device to move. The slide plate 8 slides outward along the slide groove 111. The slide rod goes out synchronously. The elastic element 4 is stretched until the discharge hole 21 and the through hole 321 are aligned and grass seeds are sown. Then the drill rod 32 is retracted. After the drill rod 32 leaves the ground, the slide plate 8 and the guide rod 5 are reset along the slide groove 111 by the elastic force of the elastic element 4. The guide rod 5 guides the slide plate 8 to avoid sliding out of the slide groove 111, which would cause the drill rod assembly 3 to separate from the body 11.

[0051] The storage box 2 has sliding frames 22 fixed on both sides of the bottom, and a sliding bracket 23 is slidably connected inside the sliding frame 22. The sliding bracket 23 is fixedly connected to the bottom of the slide plate 8. The connection between the slide plate 8 and the storage box 2 is maintained by the sliding insertion of the sliding frame 22 and the sliding bracket 23, keeping the two on the same straight line.

[0052] The storage box 2 has two gates 6 symmetrically slidably installed on the top of the discharge hole 21. The inner walls of the storage box 2 are symmetrically fixed with second drive members 7, and the extended ends of the second drive members 7 are fixed to the gates 6. The opening and closing of the gates 6 are controlled by the second drive members 7, which facilitates the delivery of grass seeds through the discharge hole 21.
