Description

Technical Field

[0001] This utility model relates to the field of agricultural production tools, specifically a support structure for laying mulch film. Background Technology

[0002] Mulching, also known as plastic film covering, refers to covering the soil with a semi-transparent, black, or other colored PE film. This increases soil temperature, retains soil moisture, and effectively maintains the soil's internal structure. Furthermore, it can suppress salinity, protect seedlings, improve soil light and heat conditions, and keep crops clean and healthy. In short, mulching improves the soil's supply and balance by maintaining and adjusting these aspects, making it more resistant to pests and microbial diseases, improving the plant's growth environment, and enhancing its overall growth capacity.

[0003] Currently, the laying of plastic film is mostly done manually. Due to the limited space inside the greenhouse, it usually requires two people to operate the machine: one person holds and unrolls the film roll, while the other person holds the film and pulls it along the ridges to lay it. Obviously, this method is time-consuming, labor-intensive, and not cost-effective. Therefore, a support structure for laying plastic film needs to be designed. Utility Model Content

[0004] The purpose of this invention is to overcome the defects and deficiencies of the existing technology and provide a support structure for laying mulch film, which can be easily laid by one person holding the mulch film and pulling it along the ridge, thereby improving efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A support structure for laying mulch film includes two supports arranged opposite each other and a load-bearing crossbar with a roll of mulch film wound around its exterior. The characteristic is that a support member is fixedly connected to the top of each support, and the two ends of the load-bearing crossbar are respectively detachably inserted into the support members on both sides, and the load-bearing crossbar can rotate between the support members on both sides.

[0007] Furthermore, each support includes a vertical rod and a tripod fixedly connected to the vertical rod, wherein the vertical rod is a telescopic rod.

[0008] Furthermore, the vertical rod includes an outer tube, and a support rod is slidably inserted into the inside of the outer tube. The top of the outer tube is provided with a transverse screw hole penetrating its inner and outer side walls, and a fastening bolt is screwed in thereon. Tightening the fastening bolt abuts against one side of the support rod, locking the support rod inside the outer tube.

[0009] Furthermore, the support member is a bearing, and the outer ring of the bearing is fixedly connected to the top end of the support rod.

[0010] Furthermore, air bladders are fixedly connected to both ends of the bearing crossbar, and inflation / deflation nozzles are connected to the air bladders. After the air bladders are inserted into the inner rings of the bearings at both ends of the bearing crossbar, they are inflated and expand to form an interference fit with the inner rings of the bearings.

[0011] Furthermore, the outer diameters at both ends of the bearing crossbar are smaller than the diameter of the inner ring of the bearing.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This utility model sets up two supports and inserts a crossbar with a roll of plastic film between them. Only one person needs to hold the plastic film and pull it along the ridge to lay it easily, saving labor and increasing efficiency. In addition, the height of the crossbar from the ground can be adjusted, and it can also be used for laying small arched greenhouse films. Moreover, the support structure is simple, inexpensive, easy to manufacture, and helps to save production costs. Attached Figure Description

[0016] Figure 3 This is a schematic diagram of the structure of a single bracket in this utility model. Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0018] See Figure 1-3 A support structure for laying mulch film includes two supports 1 arranged opposite to each other and a load-bearing crossbar 3 with a roll of mulch film 2 wound around its outside. Each support 1 has a support member 4 fixedly connected to its top end. The two ends of the load-bearing crossbar 3 are respectively detachably inserted into the support members 4 on both sides, and the load-bearing crossbar 3 can rotate between the support members 4 on both sides.

[0019] In this utility model, each bracket 1 includes a vertical rod 11 and a tripod 12 fixedly connected to the vertical rod 11. The vertical rod 11 is a telescopic rod.

[0020] In this utility model, the vertical rod 11 includes an outer tube 111, a support rod 112 is slidably inserted into the inner part of the outer tube 111, and the top of the outer tube 111 is provided with a transverse screw hole that penetrates its inner and outer side walls and is screwed with a fastening bolt 5.

[0021] Therefore, by tightening the fastening bolt 5 so that it abuts against one side of the support rod 112, the support rod 112 is locked inside the outer tube 111.

[0022] In addition, by loosening the fastening bolt 5, the locking of the support rod 112 can be released, thereby extending and retracting the support rod 112 to adjust the height of the bearing crossbar 3 above the ground.

[0023] It should be noted that, in order to ensure the locking effect and prevent the support rod 112 from loosening, several fastening bolts can be installed sequentially in the same height direction.

[0024] In this utility model, the four supporting components are bearings, and the outer ring of the bearing 4 is fixedly connected to the top of the support rod 112.

[0025] In this utility model, airbags 6 are fixedly connected to both ends of the supporting crossbar 3, and airbags 6 are connected to inflation / deflation nozzles 7.

[0026] Therefore, after the two ends of the bearing crossbar 3 are respectively inserted into the inner rings of the bearings 4, air is injected into the air bladder 6 through the air inlet / outlet nozzle 7. The air bladder 6 expands until it is in an interference fit with the inner ring of the bearing 4. At this time, the bearing crossbar 3 can rotate between the bearings 4 on both sides.

[0027] Furthermore, after releasing air through the inflation / deflation nozzle 7, the air bladder 6 deflates, allowing the supporting crossbar 3 to be pulled out from the inner ring of the bearing 4.

[0028] In this invention, the outer diameters at both ends of the bearing crossbar 3 are smaller than the diameter of the inner ring of the bearing 4, which facilitates the removal of the bearing crossbar 3 from the inner ring of the bearing 4.

[0029] The present invention will be further described below with reference to the accompanying drawings:

[0030] When laying the mulch film, first place the two supports 1 on both sides of one end of the ridge, and then insert the two ends of the bearing crossbar 3 with the mulch film roll 2 wrapped around it into the inner rings of the bearings 4 on both sides.

[0031] Next, press down on the two supports 1 respectively, so that the bottom of the tripod 12 is inserted about 10cm below the ground, thus fixing the two supports 1 to the ground.

[0032] Then, air is injected into the air bag 6 through the air inlet / outlet 7, and the air bag 6 expands until it is interference-fitted with the inner ring of the bearing 4.

[0033] Then, an operator holds the plastic film 2 and gradually pulls it along the ridge to the other end, making it easy to lay the plastic film. During this process, the supporting crossbar 3 rotates passively.

[0034] When laying the small arched greenhouse film, first place the two supports 1 on the two sides of one end of the small arched greenhouse respectively, then loosen the fastening bolts 5 to release the locking of the support rod 112, so that the support rod 112 can be extended to adjust the height of the bearing crossbar 3 from the ground.

[0035] Next, the two ends of the supporting crossbar 3, which is wrapped with a small arched membrane, are respectively inserted into the inner rings of the bearings 4 on both sides.

[0036] Then, following the above process, the small arched greenhouse film can be laid on the small arched greenhouse.
