Description

Technical Field

[0001] This utility model relates to the field of frame-mounted film covering machine technology, and in particular to a frame-mounted film covering machine for small arched greenhouses. Background Technology

[0002] In agricultural planting, small arched greenhouses are a common agricultural facility widely used in the cultivation of various crops. However, manually erecting poles to build small arched greenhouses is labor-intensive and inefficient. Currently, existing automatic pole-grabbing and pole-inserting machines for small arched greenhouse frames can only perform pole insertion; the subsequent work of covering the arched frame with film still requires film-covering and soil-covering equipment, making it impossible to complete pole insertion, film covering, and soil covering in one operation. Furthermore, existing film-covering and soil-covering equipment is not compatible with small arched greenhouse frames; even simple modifications and installations of existing film-covering and soil-covering equipment onto small arched greenhouse frame pole-inserting machines often result in poor film spreading, wrinkles, and loose film covering on the frame, leading to unsatisfactory film covering results.

[0003] Therefore, how to provide a small arched greenhouse frame mulching machine that can complete the installation of poles, mulching, and soil covering in one go, with high work efficiency and good mulching effect, is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] In view of this, the present invention proposes a small arched greenhouse frame covering machine, which aims to solve at least one of the above-mentioned technical problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: This utility model provides a small arched greenhouse frame covering machine, including: Arched canopy support mechanism A film covering and soil covering mechanism, comprising a connecting frame, a film covering and trenching assembly, a film rolling shaft, a formwork support wheel assembly, a film spreading wheel assembly, a film pressing wheel assembly, a film tightening wheel assembly, and a soil covering assembly; The front end of the connecting frame is installed at the rear end of the arched shed insert mechanism; the film covering and trenching assembly is located at the front of the connecting frame; the film rolling shaft is located above the rear of the connecting frame; the support roller assembly is located in the middle of the connecting frame and below the film rolling shaft, corresponding to the film covering and trenching assembly and the film rolling shaft; the film spreading roller assembly is located on the connecting frame, and its two sets of film spreading rollers are arranged one-to-one on the left and right sides of the connecting frame and below the support roller assembly; the front of the pressing roller assembly is located at the rear end of the connecting frame, and its two sets of pressing rollers are arranged one-to-one below the rear of the two sets of film spreading rollers; the film tightening roller assembly is connected to the pressing roller assembly, and the rear sides of the two sets of tightening rollers of the film tightening roller assembly are pressed one-to-one against the front sides of the two sets of pressing rollers; The front part of the soil covering component is located at the rear end of the connecting frame, and the two sets of soil covering discs at its rear are arranged one-to-one with the two sets of pressing rollers.

[0006] When using this utility model of small arched greenhouse frame insertion and film covering machine, the arched greenhouse frame insertion mechanism is pulled forward by a tractor or other traction equipment. The arched greenhouse frame insertion mechanism is responsible for inserting poles to build the arched greenhouse frame during the movement. The film covering and soil covering mechanism is connected to the rear end of the arched greenhouse frame insertion mechanism and moves forward together to cover the built greenhouse frame with film and cover the film edge with soil. It can realize the tasks of inserting poles to build the greenhouse frame, covering the greenhouse frame with film and covering the film edge with soil in one go. The film roll is used to install the greenhouse mold roll. Since the support wheel assembly is located below and in front of the film roll, the greenhouse film, after unfolding from the mold roll, first passes around the support wheel assembly in front and then extends backward. Two sets of film spreading wheels on both sides, working with the support wheel assembly, are responsible for flattening the greenhouse film along its width. The support wheel assembly in the middle is responsible for correcting the conveying trajectory, ensuring that the center line of the greenhouse film coincides with the center line of the arched frame. Subsequently, the rearward-extending side of the greenhouse film passes between the corresponding pressing and tightening wheels. Because the pressing and tightening wheels are positioned low and are in a compressed state, they can clamp the side of the greenhouse film passing between them. Under the lateral pulling action of the two sets of pressing and tightening wheels on both sides, the greenhouse film can be more tightly adhered to the surface of the arched frame. The soil covering plate is responsible for covering the corresponding side of the greenhouse film with soil to fix it in place. This utility model of a small arched greenhouse frame covering machine has high working efficiency and better covering effect.

[0008] The beneficial effects of the above technical solution are as follows: Adjusting the installation position of the mounting base along the length of the adjusting beam enables centering and guiding of the unrolled greenhouse film; adjusting the installation position of the telescopic support arms front and back allows the support rollers to align with the front of the film unfolding rollers on both sides, thus supporting and tautning the middle part of the unrolled greenhouse film on the mold. This also facilitates observation of the taut portion of the film to determine if it is aligned with the arched apex of the greenhouse frame. The support rollers' support and rotational damping prevent the greenhouse film on the film roll shaft from becoming loose due to excessively rapid unrolling.

[0009] As a further improvement to the above technical solution, the film covering and soil covering mechanism also includes a mounting base assembly, which includes mounting base one and mounting base two; mounting base one and mounting base two are slidably connected to the adjusting beam along the length direction of the adjusting beam, and both can be locked to the adjusting beam by fastener three.

[0010] The beneficial effect of the above technical solution is that by adjusting the lateral position of mounting base one and mounting base two, the position of the two sets of film spreading wheels and the distance between them can be adjusted.

[0013] As a further improvement to the above technical solution, the pressure roller assembly includes an adjustment bracket one, an adjustment bracket two, and two sets of pressure rollers; the front ends of the adjustment bracket one and the adjustment bracket two are hinged to the mounting base one and the mounting base two respectively; the two sets of pressure rollers are rotatably mounted on the lower rear end of the adjustment bracket one and the adjustment bracket two respectively.

[0015] As a further improvement to the above technical solution, both connecting rod one and connecting rod two are elastically retractable connecting rods; connecting rod one and connecting rod two drive the rear sides of the outer peripheral wheel surfaces of the two sets of film-tightening wheels to elastically press against the front sides of the outer peripheral wheel surfaces of the two sets of film-pressing wheels.

[0016] The beneficial effects of the above technical solution are: by designing connecting rod one and connecting rod two as elastic contraction connecting rods, the outer circumferential surfaces of the two sets of film tightening wheels can be elastically pressed against the front side of the outer circumferential surfaces of the corresponding two sets of film pressing wheels, which can effectively prevent the side of the greenhouse film from loosening and achieve a more stable film pressing and covering effect.

[0017] As a further improvement to the above technical solution, the first adjusting bracket includes a telescopic arm and a lifting arm; the second adjusting bracket includes a telescopic arm and a lifting arm. The fixed ends of telescopic boom one and telescopic boom two are hinged to mounting base one and mounting base two respectively; the upper ends of lifting boom one and lifting boom two are respectively arranged at the telescopic ends of telescopic boom one and telescopic boom two; the axles of the two sets of pressing rollers are respectively connected to the lower ends of lifting boom one and lifting boom two; one end of connecting rod one and connecting rod two are respectively connected to the lower ends of lifting boom one and lifting boom two.

[0021] As a further improvement to the above technical solution, the soil covering assembly also includes a telescopic stabilizing bar, which is arranged parallel to the adjusting beam and whose two ends are connected one-to-one to the rear ends of the first support arm and the second support arm.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0039] According to the embodiments of this utility model, such as Figures 1 to 5 As shown, the small arched greenhouse frame covering machine includes: an arched greenhouse frame mechanism 1 and a covering and soil covering mechanism 2.

[0040] The film covering and soil covering mechanism 2 includes a connecting frame 21, a film covering and trenching assembly 22, a film rolling shaft 23, a formwork support wheel assembly 24, a film spreading wheel assembly 25, a film pressing wheel assembly 26, a film tightening wheel assembly 27, and a soil covering assembly 28.

[0041] The front end of the connecting frame 21 is installed at the rear end of the arched shed insert mechanism 1; the film covering and trenching assembly 22 is located at the front of the connecting frame 21; the film rolling shaft 23 is located above the rear of the connecting frame 21, and the axial direction of the film rolling shaft 23 is along the left and right direction of the connecting frame 21; the support roller assembly 24 is located in the middle of the connecting frame 21 and below the film rolling shaft 23, corresponding to the film covering and trenching assembly 22 and the film rolling shaft 23; the film spreading roller assembly 25 is located on the connecting frame 21, and its two sets of film spreading rollers 253 are arranged one-to-one on the left and right sides of the connecting frame 21 and below the support roller assembly 24; the front of the pressing roller assembly 26 is located at the rear end of the connecting frame 21, and its two sets of pressing rollers 263 are arranged one-to-one below the rear of the two sets of film spreading rollers 253; the film tightening roller assembly 27 is connected to the pressing roller assembly 26, and the rear sides of the two sets of tightening rollers 273 of the film tightening roller assembly 27 are pressed one-to-one against the front sides of the two sets of pressing rollers 263.

[0042] The front of the soil covering component 28 is located at the rear end of the connecting frame 21, and the two sets of soil covering discs 285 at its rear are arranged one-to-one with the two sets of pressing rollers 263 behind it.

[0043] In this embodiment, the small arched greenhouse frame installation and covering machine is used by a tractor or other traction equipment to move the frame. The frame installation mechanism 1 is responsible for inserting poles to construct the arched greenhouse frame during the movement. The covering and soil covering mechanism 2 is connected to the rear end of the frame installation mechanism 1 and moves in tandem to cover the constructed frame with film and cover the edges of the film with soil. This allows for the one-time completion of the tasks of pole installation and frame construction, frame covering, and edge soil covering. The film roll 23 is used to install the greenhouse formwork roll. Since the formwork support wheel assembly 24 is located in front of and below the film roll 23, after the greenhouse film is unrolled from the formwork roll, it first passes around the formwork support wheel assembly 24 in front and then extends backward. The two sets of film spreading wheel assemblies 253 on both sides work with the formwork support wheel assembly 24 to flatten the greenhouse film along the width direction. The formwork support wheel assembly 24 in the middle is responsible for correcting the conveying trajectory to ensure that the center line of the greenhouse film coincides with the center line of the arched greenhouse frame. Subsequently, the side of the greenhouse film extending backward passes through... The film is inserted between the corresponding pressing roller 263 and tightening roller 273. Because the pressing roller 263 and tightening roller 273 are positioned low and are in a compressed state, they can clamp the side of the greenhouse film passing between them. Under the lateral pulling action of the two sets of pressing rollers 263 and tightening roller 273 on both sides, the greenhouse film can be more tightly adhered to the outer surface of the arched frame. The soil covering plate 285 is responsible for covering the corresponding side of the greenhouse film with soil to fix the film. This utility model of small arched greenhouse frame covering machine has high working efficiency and better covering effect.

[0044] Specifically, the arched canopy support mechanism 1 is existing technology and can be designed with reference to existing technology. The specific structure and working principle will not be described in detail here. The front end of the arched canopy support mechanism 1 can be connected to the rear end of the tractor and is towed forward by the tractor (which can be an agricultural tractor).

[0045] Specifically, both ends of the film roll 23 are mounted on the longitudinal beams on the left and right sides of the connecting frame 21 via bearing seats.

[0046] In some embodiments, the rear end of the connecting frame 21 has an adjusting crossbeam 211 arranged in the left-right direction; the formwork support wheel assembly 24 includes a mounting base 241, an adjusting tube 242, a telescopic support arm 243, and a formwork support wheel 244; the mounting base 241 is slidably connected to the adjusting crossbeam 211 along the length direction of the adjusting crossbeam 211, and can be locked onto the adjusting crossbeam 211 by a fastener 2411 (the fastener 2411 can be a U-bolt); the adjusting tube 242 is arranged along the front-rear direction of the connecting frame 21 and fixed on the mounting base 241; the rear part of the telescopic support arm 243 is movably inserted into the adjusting tube 242 and can be locked into the adjusting tube 242 by a fastener 2421 (the fastener 2421 can be a fastening bolt); the formwork support wheel 244 is rotatably mounted on the front part of the telescopic support arm 243 and located below the film roll shaft 23, corresponding to the film covering trenching assembly 22 and the film roll shaft 23.

[0047] Specifically, the axial direction of the rotating shaft of the support roller 244 is parallel to the axial direction of the film rolling shaft 23.

[0048] By adjusting the mounting position of the mounting base 241 along the length of the adjusting beam 211, the unrolled greenhouse film can be centered and guided. Adjusting the installation position of the telescopic support arm 243 forward and backward allows the support wheel 244 to align with the front of the two film-unrolling wheel assemblies 253, thus supporting and tightening the middle part of the unrolled greenhouse film on the mold. This also facilitates observation of the supported and protruding part of the film to determine if it is aligned with the arched apex of the greenhouse frame. The support wheel 244, with its support and rotational damping, prevents the greenhouse film on the film-rolling shaft 23 from becoming loose due to excessively rapid unrolling.

[0049] In some embodiments, the mulching and soil covering mechanism 2 further includes a mounting base assembly 29, which includes a first mounting base 291 and a second mounting base 292. The first mounting base 291 and the second mounting base 292 are slidably connected to the adjusting beam 211 along the length direction of the adjusting beam 211, and both can be locked onto the adjusting beam 211 by a third fastener 293 (which may be a U-bolt).

[0050] The film spreading wheel assembly 25 includes a first connecting plate 251, a second connecting plate 252, and two sets of film spreading wheels 253; one end of the first connecting plate 251 and the second connecting plate 252 are fixed on the first mounting base 291 and the second mounting base 292 respectively; the two sets of film spreading wheels 253 are rotatably mounted on the other end of the first connecting plate 251 and the second connecting plate 252 respectively.

[0051] Adjusting the lateral position of mounting base 1 291 and mounting base 292 can adjust the position of the two sets of film spreading wheels 253 and the distance between them.

[0052] In some embodiments, the two sets of film spreading rollers 253 include film spreading roller one 2531, film spreading roller two 2532, film spreading roller three 2533 and film spreading roller four 2534; film spreading roller one 2531 and film spreading roller two 2532 are rotatably mounted on the inner side of the opposite direction of the other end of connecting plate one 251 and connecting plate two 252, respectively; film spreading roller three 2533 and film spreading roller four 2534 are arranged on the rear side of film spreading roller one 2531 and film spreading roller two 2532 and are rotatably mounted on the inner side of the opposite direction of the other end of connecting plate one 251 and connecting plate two 252, respectively; film clamping gaps are formed between film spreading roller three 2533 and film spreading roller one 2531, and between film spreading roller four 2534 and film spreading roller two 2532.

[0053] Specifically, the axial directions of film spreading roller 1 2531, film spreading roller 2532, film spreading roller 3 2533 and film spreading roller 4 2534 are all parallel to the axial direction of film winding shaft 23.

[0054] Specifically, a strip-shaped position adjustment through hole is provided on the surface of the connecting plate 251 at the axle of the film spreading wheel 2533 along the opposite direction of the film spreading wheel 2533 and the film spreading wheel 2531. The axle of the film spreading wheel 2533 moves through the strip-shaped position adjustment through hole and can be adjusted along the length of the strip-shaped position adjustment through hole to change the distance between the film spreading wheel 2533 and the film spreading wheel 2531. The axle of the film spreading wheel 2533 can be tightened in the strip-shaped position adjustment through hole by a nut.

[0055] Similarly, on the surface of connecting plate 252, at the axle of film spreading wheel 2534, a strip-shaped position adjustment through hole 2 is provided in the direction opposite to that of film spreading wheel 2534 and film spreading wheel 2532. The axle of film spreading wheel 2534 moves through the strip-shaped position adjustment through hole 2 and can be adjusted along the length of the strip-shaped position adjustment through hole 2 to change the distance between film spreading wheel 2534 and film spreading wheel 2532. The axle of film spreading wheel 2534 can be tightened in the strip-shaped position adjustment through hole 2 by a nut.

[0056] The two sides of the unwinding mold roll are respectively clamped by the film spreading roller 3 2533 and film spreading roller 1 2531, and film spreading roller 4 2534 and film spreading roller 2 2532, which can better constrain the two sides of the mold and achieve a better flattening effect.

[0057] In some embodiments, the pressure roller assembly 26 includes an adjustment bracket 1 261, an adjustment bracket 262, and two sets of pressure rollers 263; the front ends of the adjustment bracket 1 261 and the adjustment bracket 262 are hinged to the mounting base 1 291 and the mounting base 292 respectively; the two sets of pressure rollers 263 are rotatably mounted on the lower rear end of the adjustment bracket 1 261 and the adjustment bracket 262 respectively.

[0058] The film tightening wheel assembly 27 includes a first connecting rod 271, a second connecting rod 272, and two sets of film tightening wheels 273; the first connecting rod 271 and the second connecting rod 272 correspond one-to-one to the outer side of the two sets of film tightening wheels 263 in opposite directions, and one end of each connecting rod 271 and the second connecting rod 262 are connected to the lower rear end of the first adjusting bracket 261 and the second adjusting bracket 262 respectively; the two sets of film tightening wheels 273 are rotatably mounted one-to-one to the other end of the first connecting rod 271 and the second connecting rod 272 respectively.

[0059] Both sets of pressing rollers 263 are connected to the corresponding mounting base 1 291 and mounting base 292 via adjusting brackets. When adjusting the position and spacing of mounting base 1 291 and mounting base 292, the two sets of pressing rollers 263 and their two sets of tightening rollers 273 can be adjusted synchronously.

[0060] Specifically, the adjustment bracket 1 261 and the adjustment bracket 2 262 have the same structure.

[0061] In some embodiments, both connecting rod 271 and connecting rod 272 are elastically retractable connecting rods; connecting rod 271 and connecting rod 272 drive the rear side of the outer peripheral wheel surface of the two sets of film tightening wheels 273 to elastically press against the front side of the outer peripheral wheel surface of the two sets of film pressing wheels 263.

[0062] By designing connecting rod 271 and connecting rod 272 as elastic retractable connecting rods, the outer circumferential surfaces of the two sets of film-tightening wheels 273 can be elastically pressed against the front side of the outer circumferential surfaces of the corresponding two sets of film-pressing wheels 263, which can effectively prevent the side edges of the greenhouse film from loosening and achieve a more stable film-pressing and covering effect.

[0063] Specifically, connecting rod 271 and connecting rod 272 have the same structure, both including a fixed outer tube and a telescopic inner tube. One end of the telescopic inner tube slides into the other end of the fixed outer tube.
