Description

Technical Field

[0001] This utility model relates to the field of greenhouse mulching technology, and in particular to a greenhouse mulching device for cutting propagation. Background Technology

[0002] In agricultural cutting propagation, arched greenhouses play a crucial role in creating a suitable microclimate for seedlings. Seedlings are quite fragile and extremely sensitive to environmental changes. Arched greenhouses can, to a certain extent, block adverse external climatic factors, such as cold winds, drastic temperature fluctuations, and direct rain. Mulching the greenhouse is a fundamental and core step in creating this suitable environment, and its importance is self-evident. The quality and effectiveness of mulching directly affect the successful growth and development of seedlings. Proper mulching effectively maintains the temperature inside the greenhouse, keeping it within a suitable range, providing stable warmth and heat conditions for rooting, germination, and early vigorous growth of the seedlings.

[0003] However, covering arched greenhouses with film typically requires manual transport of the entire roll of film to the arch frame, followed by unrolling and covering the frame, and then manual compaction of the soil. This process is labor-intensive and time-consuming, resulting in low efficiency. Furthermore, carelessness during transport could lead to injuries to workers. This patent provides an arched greenhouse film covering device for cutting propagation, alleviating the aforementioned technical problems in the prior art. Utility Model Content

[0004] The purpose of this utility model is to solve the problems existing in the prior art, which usually requires manual handling of the entire roll of film to the arch frame, then unfolding it and covering the arch frame, followed by manual compaction of the soil. This requires a lot of manpower and time for film covering and soil compaction, resulting in low efficiency. In addition, if care is not taken during handling, workers may be injured. Therefore, this utility model proposes a film covering device for arched greenhouses for cutting propagation.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A film covering device for arched greenhouses used for cutting propagation includes a base plate, a soil storage box fixedly connected to the side of the base plate, a flat plate slidably connected inside the soil storage box, a cam disposed below the flat plate, the cam passing through the soil storage box and rotatably connected to a first bevel gear, the first bevel gear meshing with a second bevel gear, a half-gear fixedly connected to the end of the second bevel gear away from the first bevel gear, the half-gear intermittently meshing with a first rack and a second rack, the first rack and the second rack being disposed above the inner wall of an elliptical ring, the elliptical ring being slidably connected to a sliding track, a compaction hammer fixedly connected to one side of the elliptical ring, and a film covering mechanism for covering the arch frame disposed above the base plate.

[0007] The above technical solution further includes:

[0008] The coating mechanism includes a cylinder column disposed above a base plate, a sliding column slidably connected to the cylinder column, a support frame fixedly connected above the sliding column, a coating roller for placing the coating film disposed above the support frame, a pull rod slidably connected to the coating roller, a fixing block slidably connected to the pull rod, a threaded torsion bar threadedly connected above the fixing block, and a motor disposed on one side of the coating roller.

[0009] The side of the soil storage tank is provided with a hole that communicates with the soil discharge pipe, and one end of the soil discharge pipe is provided with a crooked nozzle for sliding down to the edge of the mulch film.

[0010] Both sides of the support frame are equipped with soil storage boxes, and both sides of the support frame are equipped with compaction hammers for hammering the soil on the mulch surface.

[0011] The support frame has square slots on its surface for the side motor of the coating roller, and slits on its surface for evenly spreading the film. The square slots on the support frame surface allow the motor to be precisely and securely installed in the designated position. This ensures that the motor does not shift or wobble when driving the coating roller, thus ensuring that the film is evenly stretched and unfolded at a stable speed and tension during the coating process, improving the quality and stability of the coating.

[0012] The sliding track is fixedly connected to the soil storage tank, and the first bevel gear is rotatably connected to the soil storage tank. A connecting block for support is provided on one side of the sliding track. This connecting block further enhances the stability of the entire device during operation. Especially when the compaction hammer is performing intermittent hammering actions, the connecting block can share some of the pressure, preventing the sliding track from deforming or being damaged due to uneven stress, extending the service life of the device, and ensuring its continuous and stable operation.

[0013] The soil storage tank has a soil inlet on one side. This soil inlet greatly facilitates the operator in adding loose soil into the soil storage tank.

[0014] Tracks are installed beneath the base plate for movement. These tracks provide the entire device with excellent mobility. Operators can easily maneuver the device to different locations next to the arches for rapid positioning. Compared to traditional manual handling or relying on human power to move equipment, the tracks allow for stable operation in various terrain conditions, and the movement speed is controllable.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, the device eliminates the traditional method of manually carrying the entire roll of film and manually unfolding it for covering. Through a specific structural design, such as a movable base plate and tracks, the film-covering roller can be conveniently transported to the top of the arch frame and the film-covering process can be completed automatically. At the same time, the soil covering and compaction processes are also automated, eliminating the need for manual shoveling and compaction, greatly reducing labor input and operation time, and significantly improving the overall work efficiency of arch frame film covering, thus meeting the film covering needs of large-scale cutting propagation.

[0017] 2. In this utility model, manual handling of the film poses a risk of injury to workers. This utility model device frees workers from the heavy and dangerous handling work. Workers only need to perform some simple preparatory work and equipment operation, such as installing the film-coating roll and adjusting equipment parameters, avoiding the direct handling of heavy film, reducing the probability of safety accidents caused by improper handling, and creating a safer working environment for workers.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-5 As shown, this utility model is a mulching device for arched greenhouses used for cutting propagation, including a base plate 1. A soil storage box 3 is fixedly connected to the side of the base plate 1. A flat plate 17 is slidably connected inside the soil storage box 3. A cam 13 is provided below the flat plate 17. The cam 13 passes through the soil storage box 3 and is rotatably connected to a first bevel gear 14. The first bevel gear 14 is meshed with a second bevel gear 15. A half-gear 18 is fixedly connected to the end of the second bevel gear 15 away from the first bevel gear 14. The half-gear 18 is intermittently meshed with a first rack 19 and a second rack 20. The first rack 19 and the second rack 20 are both located above the inner wall of an elliptical ring 22. A sliding track 21 is slidably connected to the elliptical ring 22. A compaction hammer 12 is fixedly connected to one side of the elliptical ring 22. A mulching mechanism for mulching the arch frame is provided above the base plate 1.

[0026] In one embodiment, the coating mechanism includes a cylinder column 5 disposed above the base plate 1, a sliding column 6 slidably connected to the cylinder column 5, a support frame 7 fixedly connected above the sliding column 6, a coating roller 8 for placing the coating is disposed above the support frame 7, a pull rod 9 slidably connected to the coating roller 8, a fixing block 10 slidably connected to the pull rod 9, a threaded torsion bar 11 threadedly connected above the fixing block 10, and a motor disposed on one side of the coating roller 8.

[0027] In one embodiment, the soil storage box 3 has a hole on its side that communicates with the soil discharge pipe 16, and one end of the soil discharge pipe 16 has a crooked nozzle for sliding down to the edge of the mulch film.

[0028] In one embodiment, for the support frame 7, both sides of the support frame 7 are provided with soil storage boxes 3, and both sides of the support frame 7 are provided with compaction hammers 12 for hammering the soil on the surface of the mulch film.

[0029] In one embodiment, the support frame 7 has a square groove on its surface for the side motor of the coating roller 8, and the support frame 7 has a cut for evenly spreading the coating.

[0030] In this embodiment, the surface of the support frame 7 is provided with a square groove for the side motor of the coating roller 8, so that the motor can be accurately and stably installed in the designated position. This ensures that the motor will not shift or wobble when driving the coating roller 8 to rotate, thereby ensuring that the film can be stretched and unfolded evenly at a stable speed and tension during the coating process, improving the quality and stability of the coating.

[0031] In one embodiment, the sliding track 21 is fixedly connected to the soil storage tank 3, the first bevel gear 14 is rotatably connected to the soil storage tank 3, and a connecting block for support is provided on one side of the sliding track 21.

[0032] In this embodiment, a connecting block for support is provided on one side of the sliding track 21, which further enhances the stability of the entire device during operation. Especially when the compaction hammer 12 performs intermittent hammering action, the connecting block can share some of the pressure, prevent the sliding track 21 from deforming or being damaged due to uneven force, extend the service life of the device, and ensure the continuous and stable operation of the device.

[0033] In one embodiment, the soil storage box 3 is provided with an inlet 4 for placing soil on one side.

[0034] In this embodiment, a soil inlet 4 is provided on one side of the soil storage box 3 for placing soil, which greatly facilitates the operator to add loose soil into the soil storage box 3.

[0035] In one embodiment, for the aforementioned base plate 1, a track 2 for movement is provided below the base plate 1.

[0036] In this embodiment, tracks 2 are installed under the base plate 1 for movement, giving the entire device excellent mobility. Operators can easily maneuver the device to move it to different locations next to the arches, achieving rapid positioning. Compared to traditional manual handling or relying on human power to move equipment, tracks 2 can operate smoothly under different terrain conditions, and the moving speed is controllable.

[0037] The working principle of the arched greenhouse covering device for cutting propagation in this utility model is as follows: First, the covering worker twists the threaded torsion bar 11 and removes the covering roller 8 along with the motor, placing it on the ground. Next, the pull rod 9 is pulled out from the covering roller 8, and then the entire roll of covering film is inserted into the surface of the covering roller 8 through the round hole formed in the middle. After that, the covering roller 8 and the motor on the side are placed back on the support frame 7 for subsequent rotation. Then, the pull rod 9 is inserted into the pre-drilled hole on the side of the covering roller 8, and the threaded torsion bar 11 is twisted again to prevent the device from falling off the support frame 7. At this time, loose soil is added to the soil storage boxes 3 set on both sides of the support frame 7. Next, the device is moved to the fixed arched frame using the track 2 at the bottom of the base plate 1. One end of the covering film is pulled out along the square groove set on the surface of the support frame 7 and fixed to one side of the arched frame. At this time, the height of the support frame 7 can be adjusted with the help of the cylinder column 5 to adapt to arched greenhouses of different heights. Subsequently, the two tracks 2 begin to move on both sides of the arched shed. As the tracks 2 move, the membrane of the arched shed is continuously stretched, thus covering the top of the shed frame. At this time, the control cam 13 rotates, which lifts the plate 17. The loose soil then enters the soil discharge pipe 16 through the holes on the side of the soil storage box 3, thereby covering both sides of the arched membrane. Each time the cam 13 rotates, a portion of soil comes out of the soil discharge pipe 16, thus covering both sides of the arched membrane with soil.

[0038] Simultaneously, the rotation of cam 13 drives the first bevel gear 14 to rotate the second bevel gear 15. The rotation of the second bevel gear 15 drives the half-gear 18 to rotate. The rotation of the half-gear 18 first meshes with the first rack 19, causing the elliptical ring 22 fixed to the side of the first rack 19 to rise due to the meshing of the half-gear 18 with the first rack 19. Then, after the half-gear 18 has finished meshing with the first rack 19, it disengages from it and establishes a meshing relationship with the second rack 20. When the half-gear 18 meshes with the second rack 20, it causes the elliptical ring 22 to slide downward on the side wall of the sliding track 21, thereby causing the compaction hammer 12 to intermittently hammer the covered ground, thus compacting the soil.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
