Description

Technical Field

[0001] This utility model belongs to the field of planting technology, and in particular to a tobacco planting mulch device. Background Technology

[0002] In tobacco cultivation, tobacco seedlings are quite fragile, so mulching is necessary in the early stages of planting. However, most mulching devices are not convenient for easy installation and removal of the film rolls, making it inconvenient for personnel to replace the film rolls after mulching, thus reducing the efficiency of the device when mulching tobacco.

[0003] An existing Chinese patent (authorization announcement number CN215736112U) discloses an agricultural planting mulching device, which "includes a moving mechanism, including a platform for driving the mulching device to move; and a film mechanism, disposed on the moving mechanism, including a drive component disposed on the moving mechanism and a mulching component disposed below the moving mechanism, wherein the drive component is used to provide power for the device to automatically mulch."

[0004] It is evident that the cited patent document suffers from the problem of inconvenience in replacing the coated film roll. Utility Model Content

[0005] The purpose of this invention is to provide a tobacco planting mulching device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a tobacco planting mulching device, comprising a mulching moving frame, wherein the inner cavity of the mulching moving frame is provided with an inverted L-shaped lifting frame, the inner side wall of the lifting frame is rotatably connected to a fixed cylinder via a rotating shaft, the outer circumference of the fixed cylinder is fitted with a mulching roller for mulching tobacco, the inner side wall of the fixed cylinder is rotatably connected to a first bidirectional threaded rod via a pin, the circumference of the first bidirectional threaded rod is threaded with two abutments, the inner side wall of the fixed cylinder is symmetrically connected with four springs, the free ends of every two springs are connected to a pad, the opposite sides of the two pads are symmetrically connected with four connecting blocks, the free ends of every two connecting blocks penetrate the fixed cylinder and are connected to an extrusion block for fixing the mulching roller.

[0007] Preferably, the inner wall of the film-coating moving frame is rotatably connected to two second bidirectional threaded rods via pins, and two moving blocks are threadedly sleeved on the periphery of each of the two second bidirectional threaded rods.

[0008] Preferably, two limiting plates are symmetrically installed on the inner sidewall of the film-coated moving frame, and the four moving blocks are respectively slidably sleeved on the periphery of the two limiting plates.

[0009] Preferably, a hinge plate is hinged to the bottom surface of each pair of movable blocks, and a hinge seat is hinged to the free end of each hinge plate.

[0010] Preferably, two of the hinge seats are jointly installed on the top surface of the lifting frame, and the bottom surfaces of the other two hinge seats are jointly installed with a mounting bracket.

[0011] Preferably, the inner wall of the mounting bracket is rotatably connected to a bidirectional lead screw via a pin, and a movable plate is threaded around the bidirectional lead screw.

[0012] Preferably, each of the two movable plates has a pressing wheel for pressing the film roll rotatably connected to one of their opposite sides via a rotating rod.

[0013] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0014] This tobacco planting mulching device provides power for the movement of two abutment blocks by rotating the first bidirectional threaded rod, thereby pushing the pad block to move longitudinally. This allows the two extrusion blocks to abut against the inner wall of the mulching roller, thus fixing the mulching roller in place. Compared to existing devices for mulching tobacco, this device only requires rotating the first bidirectional threaded rod to disassemble and install the mulching roller with the film roll, making it convenient to replace with a new mulching roller.

[0015] By rotating the second bidirectional threaded rod, the mulching roller can move longitudinally, thus adapting to the ridging of tobacco fields at different heights and allowing the mulching roller to be as close as possible to the ridging of tobacco fields.

[0016] By rotating the bidirectional lead screw, two movable plates and pressing rollers can be moved to perform lateral reciprocating motion, thereby allowing adjustments to be made according to the different widths of tobacco field ridging. Attached Figure Description

[0024] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0025] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0026] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0027] like Figures 1 to 4 The tobacco planting mulching device shown includes a mulching mobile frame 1. The bottom surface of the mulching mobile frame 1 is equipped with four casters, and the top surface of the mulching mobile frame 1 is equipped with a push handle, so that personnel can push the push handle to move the mulching mobile frame 1 to the work area via the four casters.

[0028] The inner cavity of the film-coating moving frame 1 is provided with an inverted L-shaped lifting frame 2. The inner side wall of the lifting frame 2 is rotatably connected to a fixed cylinder 3 via a rotating shaft. The outer periphery of the fixed cylinder 3 is fitted with a film-coating roller 4 for coating tobacco. The film roll is wound around the periphery of the film-coating roller 4 to coat the tobacco. The inner cavity of the film-coating roller 4 is hollowed out. The film roll on the film-coating roller 4 is pulled out, and the end of the film roll is fixed to the ground. Then, the personnel push the film-coating moving frame 1 to move, so that the tobacco can be coated.

[0029] The inner wall of the fixed cylinder 3 is rotatably connected to a first bidirectional threaded rod 5 via a pin. Two abutments 6 are threaded around the circumference of the first bidirectional threaded rod 5. Four springs 7 are symmetrically connected to the inner wall of the fixed cylinder 3. The free ends of every two springs 7 are connected to a pad 8. Four connecting blocks 9 are symmetrically connected to opposite sides of the two pads 8. The free ends of every two connecting blocks 9 pass through the fixed cylinder 3 and are connected to an extrusion block 10 for fixing the coating roller 4. By rotating the first bidirectional threaded rod 5, the two abutments 6 can be moved in opposite directions, so that the two abutments 6 can abut against the two sides of the two pads 8. Since the two sides of the two abutments 6 and the two sides of the two pads 8 are at an angle... With the same inclined plane, once the two abutments 6 can abut against the two pads 8, continue rotating the first bidirectional threaded rod 5. This will allow the two abutments 6 to push the two pads 8, causing the two pads 8 to move in opposite directions and compress the spring 7. The spring 7 will deform under pressure, buffering the force and achieving a damping effect. This will cause the two pads 8 to move in opposite directions, which will in turn drive the two connecting blocks 9 and the two extrusion blocks 10 to move in opposite directions. This will allow the two extrusion blocks 10 to abut against the inner wall of the coating roller 4. At this point, continue rotating the first bidirectional threaded rod 5, which will allow the two extrusion blocks 10 to press against the inner wall of the coating roller 4, thereby fixing the coating roller 4 and facilitating the coating of tobacco.

[0030] After the film rolls around the coating roller 4 are used up, the first bidirectional threaded rod 5 is rotated in the opposite direction, which will drive the two abutments 6 to move in opposite directions and thus move them away from the two pads 8. Then, through the rebound of the spring 7, the pads 8, connecting blocks 9 and extrusion blocks 10 will move in opposite directions, thereby shortening the distance between the two extrusion blocks 10. This will eliminate the need to fix the coating roller 4, making it easier to replace the coating roller 4 with a new one. This avoids the problem of inconvenience for personnel to replace the film rolls after coating is completed, and improves the efficiency of coating tobacco.

[0031] One end of the first bidirectional threaded rod 5 passes through the fixed cylinder 3 and is connected to a knob, which facilitates the rotation of the first bidirectional threaded rod 5 by personnel.

[0032] The inner wall of the film-coating moving frame 1 is rotatably connected to two second bidirectional threaded rods 11 via pins. One end of each of the two second bidirectional threaded rods 11 passes through the film-coating moving frame 1 and is connected to a handle, which facilitates the rotation of the second bidirectional threaded rods 11 by personnel. Two moving blocks 12 are threadedly sleeved on the periphery of each of the two second bidirectional threaded rods 11. Two limiting plates 19 are symmetrically installed on the inner wall of the film-coating moving frame 1. The four moving blocks 12 are slidably sleeved on the periphery of the two limiting plates 19. By rotating the handle, the personnel can drive the second bidirectional threaded rods 11 to rotate, thereby driving the two moving blocks 12 to move in relative or opposite directions. When the moving blocks 12 move on the periphery of the second bidirectional threaded rods 11, they will move on the periphery of the limiting plates 19, which can limit the movement trajectory of the moving blocks 12.

[0033] Each pair of moving blocks 12 has a hinge plate 13 hinged to its bottom surface, and each hinge plate 13 has a hinge seat 14 hinged to its free end. The two hinge seats 14 are installed together on the top surface of the lifting frame 2. When the operator turns the handle, the two moving blocks 12 are moved in opposite directions through the second bidirectional threaded rod 11, which will drive the two hinge plates 13 to move respectively. Since the two ends of the two hinge plates 13 are hinged to the moving blocks 12 and the hinge seats 14 respectively, and the two hinge plates 13 are set at an inclination, when the two moving blocks 12 drive the hinge plates 13 to move, the lifting frame 2 will be driven to move downward through the hinge seats 14, thereby driving the fixed cylinder 3 and the film covering roller 4 to move downward. This allows for adjustment according to the different heights of the tobacco field ridges, making it convenient to cover the tobacco field ridges at different heights with film.

[0034] The bottom surfaces of the other two hinge seats 14 are jointly equipped with mounting brackets 15. The inner sidewall of the mounting bracket 15 is rotatably connected to a bidirectional lead screw 16 via a pin. One end of the bidirectional lead screw 16 passes through the mounting bracket 15 and is connected to a knob with the same connection structure as the first bidirectional threaded rod 5, facilitating the rotation of the bidirectional lead screw 16. Movable plates 17 are threaded around the periphery of the bidirectional lead screw 16. The opposite sides of the two movable plates 17 are rotatably connected to pressing rollers 18 for pressing the film roll via rotating rods. The other two bidirectional threaded rods 11, two moving blocks 12, and two hinges are also present. The connecting plate 13 and the two hinge seats 14 can drive the mounting frame 15 to perform longitudinal reciprocating motion, thereby driving the pressing roller 18 to perform longitudinal reciprocating motion, so that the pressing roller 18 can squeeze the film roll. By turning the knob, the operator can drive the bidirectional screw 16 to rotate, thereby driving the two movable plates 17 to move in opposite directions, and then driving the two pressing rollers 18 to move in opposite directions. This allows the two pressing rollers 18 to be adjusted according to the width of the tobacco field ridges, which is convenient for pressing the film after covering the ridges of different widths of tobacco fields.

[0035] A slide bar is installed on the inner wall of the mounting bracket 15 above the bidirectional lead screw 16. Both movable plates 17 are slidably sleeved on the periphery of the slide bar, which can limit the movement trajectory of the movable plates 17 and prevent deviation.

[0036] Working principle:

[0037] The tobacco planting mulching device moves the mulching frame 1 to the working area, then places the mulching roller 4 with the film roll on the outer circumference of the fixed cylinder 3. Turning the knob rotates the first bidirectional threaded rod 5, causing the two abutments 6 to move in opposite directions, so that the two abutments 6 can abut against the two sides of the two pads 8. Since the two sides of the two abutments 6 and the two sides of the two pads 8 are all inclined planes with the same angle, once the two abutments 6 abut against the two pads 8, continuing to rotate the first bidirectional threaded rod 5 allows the two abutments 6 to push the two pads 8, causing the two pads 8 to move in opposite directions and compress the spring 7, thereby driving the two connecting springs 7 and 8 respectively. The connecting block 9 and the two extrusion blocks 10 move in opposite directions, allowing the two extrusion blocks 10 to abut against the inner wall of the coating roller 4. At this time, if the first bidirectional threaded rod 5 is rotated, the two extrusion blocks 10 can squeeze the coating roller 4, thereby fixing the coating roller 4 and allowing subsequent coating processing. If the film roll is used up, the first bidirectional threaded rod 5 is rotated in the opposite direction, which will drive the two abutment blocks 6 to move in opposite directions, thereby removing them from between the two pads 8. Then, through the rebound of the spring 7, the pads 8, connecting block 9 and extrusion blocks 10 can be moved in opposite directions, thereby canceling the fixing of the coating roller 4, facilitating the replacement of a new coating roller 4 and improving the efficiency of coating tobacco.
