Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of tobacco field mulch recycling device technology, especially relate to a tobacco field mulch recycling device. BACKGROUND

[0002] The tobacco field mulch recycling device is an agricultural machine or tool combination specially designed for recycling and processing the mulch used in tobacco fields. Mulch is widely used in agricultural production to improve soil temperature, retain soil moisture, and inhibit weed growth, etc. However, if the mulch is not recycled in time after the crops are harvested, it will pollute the soil and affect subsequent agricultural production.

[0003] For example, the Chinese patent with publication number CN212259987U discloses a tobacco field mulch uncovering and recycling device, which includes a support frame, a bottom wheel, an upper wheel, and a mulch divider. The support frame has a first shaft and a second shaft parallel to each other at one end. The bottom wheel is fixedly installed on the first shaft, and the upper wheel is fixedly installed on the second shaft. The bottom wheel has a first gear near one end of the support frame, and the upper wheel has a second gear near one end of the support frame. The first gear and the second gear are located on the same plane and are meshed or connected by a chain, allowing the bottom wheel and the upper wheel to rotate synchronously. The mulch divider is arranged at the end of the first shaft away from the support frame and between the bottom wheel and the upper wheel. The use of this device prevents mulch damage during uncovering, making the recycling more complete and greatly improving the mulch recycling efficiency, saving labor input for tobacco farmers, and the device is simple in structure and easy to manufacture.

[0004] The above-mentioned patent has the following problems:

[0005] The above-mentioned tobacco field mulch uncovering and recycling device has some shortcomings when in use, such as the inability to adjust the distance between the brushes according to the type and thickness of the mulch, which may not be suitable for mulch of different thicknesses. In view of this, we propose a tobacco field mulch recycling device. UTILITY MODEL CONTENTS

[0006] The utility model aims to provide a tobacco field mulch recycling device to solve the problems raised in the background.

[0007] Therefore, the utility model provides a tobacco field mulch recycling device, which further includes:

[0008] The bracket is fixedly connected to the tobacco field mulch recycling device, and two first sliding grooves are formed in the bracket and connected to the outside. Two sliding blocks are slidably connected in the first sliding grooves, and a bidirectional threaded rod is threadedly connected between the two sliding blocks.

[0009] Multiple fixing plates are fixedly connected to one end of multiple sliders, and two slots are provided on each fixing plate, with a brush inserted between the two slots;

[0010] Multiple fixing components are located within multiple fixing plates and are used to fix multiple brushes respectively;

[0011] Two first rotating slots are symmetrically opened in the bracket and are respectively connected to two first sliding slots. Two rotating rods are rotatably connected in the two first rotating slots, and one end of each rotating rod extends into the two first sliding slots and is fixed to one end of each of the two bidirectional threaded rods.

[0012] A rotating assembly, located within a bracket, is used to drive two rotating rods to rotate.

[0013] Based on the above structure, the first sliding groove, slider, fixing plate, and brush ensure that multiple sliders can slide in the two first sliding grooves respectively, and drive multiple brushes to move through the multiple fixing plates. The bidirectional threaded rod, first rotating groove, and rotating rod ensure that the rotating rod can rotate in the first rotating groove, allowing the rotating rod to drive the bidirectional threaded rod to rotate in the first sliding groove. When the bidirectional threaded rod rotates, the corresponding two sliders will be brought closer or further apart by the action of the thread of the bidirectional threaded rod, ensuring that the user can adjust the spacing between the multiple brushes. The rotating component ensures that the user can drive the two rotating rods to rotate through the rotating component. The slots and brushes ensure that the brushes can be inserted between the corresponding two slots, and ensure that when the brushes are damaged during long-term use, the user can pull the brushes out from between the corresponding two slots for replacement. The fixing component ensures that the user can fix the brushes between the corresponding two slots through the fixing component.

[0014] In the above technical solution, the fixing component further includes:

[0015] Two second sliding grooves are symmetrically opened in the fixed plate and are respectively connected to two slots. Two insert rods are slidably connected in each of the two second sliding grooves. One end of each insert rod passes through the brush and extends into the brush to engage with it. The insert rods are provided with extrusion grooves. The other end of each insert rod is fixedly connected to a spring that is fixed to the inner wall of the second sliding groove.

[0016] The third slide groove is formed inside the fixed plate and is connected to the two second slide grooves. A pressing block is slidably connected inside the third slide groove, and both ends of the pressing block extend into the two pressing grooves respectively. A pressing block is fixedly connected to the pressing block, and one end of the pressing block penetrates the inner wall of the third slide groove and extends to the outside to be slidably connected to the fixed plate.

[0017] In this technical solution, when the brush is damaged during prolonged use, the user presses the pressing block by hand, causing it to move the squeezing block within the third slide groove. This causes the two ends of the squeezing block to press against the inner walls of the two squeezing grooves, bringing the two insert rods closer together. When the two insert rods approach each other, they compress the two springs. Simultaneously, one end of each insert rod enters the two second slide grooves from inside the brush, releasing the brush's fixation. The user then manually pulls the brush out from between the two slots and replaces it. After replacement, the user inserts the replaced brush between the two slots and releases the pressing block. This allows one end of each insert rod to be pushed back by the springs, inserting it into the brush from the two second slide grooves, ensuring the brush is fixed between the two slots and cannot move.

[0018] In the above technical solution, the two ends of the extrusion block are further inclined.

[0019] In this technical solution, it is ensured that when the two ends of the extrusion block extrude the two extrusion grooves respectively, the two extrusion grooves can drive the two insert rods to move closer to each other.

[0020] In the above technical solution, furthermore, the two ends of the extrusion block are respectively inserted into two extrusion grooves.

[0021] In this technical solution, it is ensured that when the user presses the pressing block, the pressing block can drive the two ends of the extrusion block to be inserted into the two extrusion grooves respectively.

[0022] In the above technical solution, the rotating component further includes:

[0023] Two gear slots are symmetrically opened in the bracket and are respectively connected to two first rotating slots. A first bevel gear and a second bevel gear are rotatably connected in the gear slots and mesh with each other. One end of the first bevel gear passes through the inner wall of the gear slot and extends into the first rotating slot and is fixed to the other end of the rotating rod.

[0024] The second rotating groove is formed inside the bracket and is connected to two gear grooves respectively. A rotating rod is rotatably connected inside the second rotating groove, and one end of the rotating rod passes through one of the gear grooves and extends to the outside to be fixed to the two second bevel gears.

[0025] In this technical solution, during use, the user manually rotates the rotating rod, causing the two second bevel gears to rotate in their respective gear slots. These second bevel gears then drive the two first bevel gears to rotate in their respective gear slots. As the first bevel gears rotate, they drive the two rotating rods to rotate in their respective first rotating slots. These rotating rods then drive the two bidirectional threaded rods to rotate in their respective first sliding grooves. When the bidirectional threaded rods rotate, the corresponding two sliders are brought closer together by the opposing threads on the rods. This allows multiple sliders to move multiple brushes via multiple fixed plates, bringing the corresponding brushes closer together. When the brushes reach the desired position, the user stops rotating the rotating rod, ensuring that the user can adjust the spacing between the brushes according to their needs.

[0026] In the above technical solution, one end of the first bevel gear is rotatably connected to the first rotating groove.

[0027] In this technical solution, it is ensured that when the first bevel gear rotates, one end of the first bevel gear can rotate within the first rotating groove.

[0028] In the above technical solution, one end of the rotating rod is rotatably connected to one of the gear slots.

[0029] In this technical solution, it is ensured that when the rotating rod rotates, one end of the rotating rod can rotate within one of the gear slots.

[0030] In the above technical solution, furthermore, the two threads on the bidirectional threaded rod have opposite directions of rotation.

[0031] In this technical solution, it is ensured that when the bidirectional threaded rod rotates, the corresponding two sliders will be brought closer to or moved away from each other by the action of the bidirectional threaded rod.

[0032] The beneficial effects of this utility model are:

[0033] 1. This tobacco field mulch film recycling device, through the setting of a first chute, sliders, fixing plates, and brushes, ensures that multiple sliders can slide in two first chutes respectively, and each slider drives multiple brushes to move through multiple fixing plates. Through the setting of a bidirectional threaded rod, a first rotating groove, and a rotating rod, it ensures that the rotating rod can rotate in the first rotating groove, allowing the rotating rod to drive the bidirectional threaded rod to rotate in the first chute. When the bidirectional threaded rod rotates, the corresponding two sliders will be brought closer or further apart by the force of the threaded rod, ensuring that the user can adjust the spacing between the multiple brushes. Through the setting of a rotating component, it ensures that the user can drive two rotating rods to rotate through the rotating component. This solves the problem that tobacco field mulch film removal and recycling devices cannot adjust the spacing between brushes according to the type and thickness of the mulch film, which would prevent the device from adapting to mulch film of different thicknesses.

[0034] 2. This tobacco field mulch film recycling device, through the setting of slots and brushes, ensures that the brush can be inserted between the corresponding two slots, and ensures that when the brush is damaged during long-term use, the user can pull the brush out from between the corresponding two slots for replacement. Through the setting of fixing components, the user can ensure that the brush can be fixed between the corresponding two slots. Attached Figure Description

[0047] Example 1:

[0048] Please see Figure 1 - Figure 5 As shown, this embodiment provides a tobacco field mulch film recycling device, including a tobacco field mulch film recycling device 1, and further comprising:

[0049] Support 2 is fixedly connected to tobacco field plastic film recycling device 1. Support 2 has two first sliding grooves 3 that are connected to the outside. Two sliders 4 are slidably connected in the first sliding grooves 3. A bidirectional threaded rod 8 is threaded between the two sliders 4.

[0050] Multiple fixing plates 5 are fixedly connected to one end of multiple sliders 4 respectively. Two slots 6 are opened on the fixing plates 5, and a brush 7 is inserted between the two slots 6.

[0051] Multiple fixing components are located within multiple fixing plates 5 and are used to fix multiple brushes 7 respectively;

[0052] Two first rotating grooves 9 are symmetrically opened in the bracket 2 and are respectively connected to two first sliding grooves 3. Two rotating rods 10 are rotatably connected in the two first rotating grooves 9, and one end of the two rotating rods 10 extends into the two first sliding grooves 3 and is respectively fixed to one end of the two bidirectional threaded rods 8.

[0053] The rotating assembly is located inside the bracket 2 and is used to drive the two rotating rods 10 to rotate.

[0054] Example 2:

[0055] This embodiment provides a tobacco field mulch film recycling device, which, in addition to the technical solutions of the above embodiments, also has the following technical features, including a fixing component:

[0056] Two second slide grooves 11 are symmetrically opened in the fixed plate 5 and are respectively connected to two slots 6. Two insert rods 12 are slidably connected in the two second slide grooves 11, and one end of the two insert rods 12 passes through the brush 7 and extends into the brush 7 to engage with the brush 7. The insert rods 12 are provided with extrusion grooves 13, and the other end of the insert rods 12 is fixedly connected to a spring 14 that is fixed to the inner wall of the second slide groove 11.

[0057] The third slide 15 is formed inside the fixed plate 5 and is connected to the two second slides 11. A pressing block 16 is slidably connected inside the third slide 15, and both ends of the pressing block 16 extend into the two pressing grooves 13 respectively. A pressing block 17 is fixedly connected to the pressing block 16, and one end of the pressing block 17 penetrates the inner wall of the third slide 15 and extends to the outside to be slidably connected to the fixed plate 5.

[0058] When brush 7 is damaged during prolonged use, the user presses the pressing block 17, causing the pressing block 17 to move the squeezing block 16 within the third slide groove 15. This causes the two ends of the squeezing block 16 to squeeze the inner walls of the two squeezing grooves 13, which in turn cause the two squeezing grooves 13 to bring the two insert rods 12 closer together. When the two insert rods 12 come closer together, they compress the two springs 14. Simultaneously, one end of each insert rod enters the two second slide grooves 11 from inside brush 7. At this point, the brush 7 is released from its fixation. The user then pulls brush 7 out from between the two slots 6 and replaces it. After replacement, the user inserts the replaced brush 7 between the two slots 6 and releases the pressing block 17. This allows one end of each insert rod to be pushed back by the two springs 14 and inserted into the brush 7 from the two second slide grooves 11, ensuring that brush 7 is fixed between the two slots 6 and cannot move.

[0059] Example 3:

[0060] This embodiment provides a tobacco field mulch film recycling device, which, in addition to the technical solution of the above embodiment, also has the following technical features: the two ends of the extrusion block 16 are inclined.

[0061] Specifically, it is ensured that when the two ends of the extrusion block 16 extrude the two extrusion grooves 13 respectively, the two extrusion grooves 13 can respectively drive the two insertion rods 12 to move closer to each other.

[0062] Example 4:

[0063] This embodiment provides a tobacco field mulch film recycling device, which, in addition to the technical solution of the above embodiment, also has the following technical features: the two ends of the extrusion block 16 are respectively inserted and engaged with two extrusion grooves 13.

[0064] Specifically, when the user presses the pressing block 17, the pressing block 17 can drive the two ends of the squeezing block 16 to be inserted into the two squeezing grooves 13 respectively.

[0065] Example 5:

[0066] This embodiment provides a tobacco field plastic film recycling device, which, in addition to the technical solutions of the above embodiments, also has the following technical features: the rotating component includes:

[0067] Two gear slots 18 are symmetrically opened in the bracket 2 and are respectively connected to two first rotating slots 9. A first bevel gear 19 and a second bevel gear 20 are rotatably connected in the gear slots 18, and the first bevel gear 19 and the second bevel gear 20 mesh with each other. One end of the first bevel gear 19 passes through the inner wall of the gear slot 18 and extends into the first rotating slot 9 and is fixed to the other end of the rotating rod 10.

[0068] The second rotating groove 21 is opened in the bracket 2 and is connected to the two gear grooves 18 respectively. A rotating rod 22 is rotatably connected in the second rotating groove 21, and one end of the rotating rod 22 passes through one of the gear grooves 18 and extends to the outside to be fixed to the two second bevel gears 20.

[0069] In operation, the user manually rotates the rotating rod 22, causing the two second bevel gears 20 to rotate within the two gear slots 18. These second bevel gears 20 then drive the two first bevel gears 19 to rotate within the gear slots 18. As the first bevel gears 19 rotate, they drive the two rotating rods 10 to rotate within the two first rotating grooves 9. These rotating rods 10 then drive the two bidirectional threaded rods 8 to rotate within the two first sliding grooves 3. When the bidirectional threaded rods 8 rotate, the corresponding two sliders 4 are brought closer together by the opposing threads on the two sections of the bidirectional threaded rod 8. This causes the multiple sliders 4 to move through the multiple fixing plates 5, moving the corresponding two brushes 7 closer together. When the multiple brushes 7 reach the desired position, the user stops rotating the rotating rod 22, allowing the user to adjust the spacing between the multiple brushes 7 according to their needs.

[0070] Example 6:

[0071] This embodiment provides a tobacco field mulch film recycling device, which, in addition to the technical solutions of the above embodiments, also has the following technical features: one end of the first bevel gear 19 is rotatably connected to the first rotating groove 9.

[0072] Specifically, it is ensured that when the first bevel gear 19 rotates, one end of the first bevel gear 19 can rotate within the first rotating groove 9.

[0073] Example 7:

[0074] This embodiment provides a tobacco field mulch film recycling device, which, in addition to the technical solutions of the above embodiments, also has the following technical features: one end of the rotating rod 22 is rotatably connected to one of the gear slots 18.

[0075] Specifically, it is ensured that when the rotating rod 22 rotates, one end of the rotating rod 22 can rotate within one of the gear slots 18.

[0076] Example 8:

[0077] This embodiment provides a tobacco field mulch film recycling device, which, in addition to the technical solution of the above embodiment, also has the following technical features: the two sections of thread on the bidirectional threaded rod 8 have opposite directions of rotation.

[0078] Specifically, it is ensured that when the bidirectional threaded rod 8 rotates, the two corresponding sliders 4 will be brought closer to or moved away from each other by the action of the thread of the bidirectional threaded rod 8.

[0079] In use, the user manually rotates the rotating rod 22, causing the two second bevel gears 20 to rotate within the two gear slots 18, which in turn drive the two first bevel gears 19 to rotate within the gear slots 18. When the two first bevel gears 19 rotate, they drive the two rotating rods 10 to rotate within the two first rotating grooves 9, which in turn drive the two bidirectional threaded rods 8 to rotate within the two first sliding grooves 3. When the bidirectional threaded rods 8 rotate, the corresponding two sliders 4 are brought closer together by the opposing threads on the two sections of the bidirectional threaded rods 8. This causes the multiple sliders 4 to move the multiple brushes 7 via the multiple fixing plates 5, bringing the corresponding two brushes 7 closer together. When the multiple brushes 7 move to the appropriate position, the user stops rotating the rotating rod 22, ensuring that the user can adjust the spacing between the multiple brushes 7 according to usage requirements. When the brushes 7 are used for a long time... When the brush 7 is damaged during use, the user presses the pressing block 17 with their hand, causing the pressing block 17 to move the squeezing block 16 within the third slide groove 15. This causes the two ends of the squeezing block 16 to squeeze the inner walls of the two squeezing grooves 13, which in turn cause the two squeezing grooves 13 to move the two insert rods 12 closer together. When the two insert rods 12 move closer together, they compress the two springs 14. At the same time, one end of each insert rod enters the two second slide grooves 11 from the brush 7. At this point, the brush 7 is released from its fixation. The user then pulls the brush 7 out from between the two slots 6 and replaces it. After replacement, the user inserts the replaced brush 7 into the two slots 6 and releases the pressing block 17. This allows one end of each insert rod to be pushed back by the two springs 14 and inserted into the brush 7 from the two second slide grooves 11, ensuring that the brush 7 is fixed between the two slots 6 and cannot move.

[0080] The embodiments of this application have been described above with reference to the accompanying drawings.
