Description

Technical Field

[0001] The utility model belongs to the technical field of film coating devices, and more specifically, particularly relates to a film coating device. Background Art

[0002] Agriculture is an industry that uses the growth and development laws of animals and plants to obtain products through artificial cultivation. When planting potatoes, beans, and vegetables in the field, it is often necessary to ridge the land. After ridge formation, the ridges are often covered with film to facilitate the planting of potatoes, beans, and vegetables. When covering the film, a film covering device is required.

[0003] Although the existing device is provided with a covering plate to achieve synchronous covering of both sides of the ground film, the covering plate is not convenient in adjusting the angle and needs to be manually locked after the angle is adjusted, which is cumbersome to operate. In addition, the angle needs to be adjusted one by one, which wastes time. Utility Model Content

Two mounting blocks with rectangular block structures are welded on the bottom of the vehicle body. A first mounting rod with a stepped shaft structure is inserted into the two mounting blocks. A ground film roller is sleeved on the first mounting rod. The ground film roller is located at the bottom of the vehicle body, and a locking nut is threadedly connected to the right end of the first mounting rod.

[0008] Furthermore, a covering assembly is installed on the vehicle body, and the covering assembly consists of a mounting shaft, a covering plate, a worm gear and a worm. Two mounting shafts are rotatably connected to the vehicle body, and a covering plate is fixed on each mounting shaft, and the covering plate is a rectangular plate-shaped structure.

[0009] Furthermore, a worm wheel is welded on each of the mounting shafts, and two worms are rotatably connected to the vehicle body. The two worms are meshed with the two worm wheels, and the spiral teeth on the two worms are in opposite directions.

[0010] Furthermore, the two worms are connected by welding.

[0011] Furthermore, an auxiliary component is welded on the top of the vehicle body, the auxiliary component consists of a second mounting rod and a counterweight block, four second mounting rods are welded on the top surface, the four second mounting rods are all cylindrical rod-shaped structures, and four counterweight blocks are commonly sleeved on the four second mounting rods.

[0028] The implementation of the utility model is further described in detail below in conjunction with the drawings and examples. Example

[0029] As attached Figure 1 To Attachment Figure 6 As shown:

[0030] The utility model provides a film covering device, comprising a vehicle body 1; four rollers 101 are rotated on the vehicle body 1, and the four rollers 101 are in contact with the ground; a traction seat 102 for connecting to an agricultural vehicle is welded on the front end surface of the vehicle body 1; and a laying component 2 is installed on the vehicle body 1.

[0031] Among them, the laying component 2 is composed of a mounting block 201, a first mounting rod 202, a ground film roller 203 and a locking nut 204. Two mounting blocks 201 with rectangular block structures are welded at the bottom of the vehicle body 1. A first mounting rod 202 with a stepped shaft structure is inserted into the two mounting blocks 201. The ground film roller 203 is sleeved on the first mounting rod 202. The ground film roller 203 is located at the bottom of the vehicle body 1. A locking nut 204 is threadedly connected to the right end of the first mounting rod 202. When installing the ground film roller 203, the first mounting rod 202 is passed through the mounting block 201 on the left, and then through the ground film roller 203, and then through a mounting block 201 on the right, and the locking nut 204 is threadedly connected to the first mounting rod 202.

[0032] Among them, a covering component 3 is installed on the vehicle body 1, and the covering component 3 consists of a mounting shaft 301, a covering plate 302, a worm gear 303 and a worm 304. Two mounting shafts 301 are rotatably connected to the vehicle body 1, and a covering plate 302 is fixed on each mounting shaft 301, and the covering plate 302 is a rectangular plate structure.

[0033] A worm wheel 303 is welded on each mounting shaft 301 , and two worms 304 are rotatably connected to the vehicle body 1 . The two worms 304 are meshed with the two worm wheels 303 , and the spiral teeth on the two worms 304 are in opposite directions.

[0034] Among them, the two worm gears 304 are welded together. When adjusting the angle of the cover plate 302, any one of the worm gears 304 can be rotated. When the worm gear 304 is rotated, the two worm wheels 303 can be synchronously driven in reverse under the drive of the worm gear 304. When the worm wheel 303 rotates, it can drive the installation shaft 301 and the cover plate 302 to adjust the angle.

[0035] Among them, an auxiliary component 4 is welded on the top of the vehicle body 1, and the auxiliary component 4 is composed of a second mounting rod 401 and a counterweight block 402. Four second mounting rods 401 are welded on the top surface, and the four second mounting rods 401 are all cylindrical rod-shaped structures. Four counterweight blocks 402 are commonly sleeved on the four second mounting rods 401. During use, the weight of the vehicle body 1 can be increased by the four counterweight blocks 402, thereby avoiding incomplete coverage due to the light weight of the vehicle body 1.

[0036] Among them, the four counterweight blocks 402 are all T-shaped block structures. When installing and disassembling the counterweight blocks 402, hands can be inserted into the front and rear sides of the counterweight blocks 402, which facilitates the disassembly and assembly of the counterweight blocks 402. Example

[0037] Based on the first embodiment, the upper ends of the four second mounting rods 401 are polished. After polishing, the upper ends of the four second mounting rods 401 are all arc-shaped structures, which makes it more convenient and quick to install the counterweight 402 on the second mounting rod 401.

[0038] Working principle: When installing the mulch roller 203, the first mounting rod 202 is passed through the mounting block 201 on the left, then through the mulch roller 203, and then through a mounting block 201 on the right, and the locking nut 204 is threadedly connected to the first mounting rod 202;

[0039] When in use, the traction seat 102 is connected to the agricultural vehicle, and the head end of the ground film is buried with soil on the ridge. When the agricultural vehicle moves forward, it can drive the ground film roller 203 to move forward. At this time, the ground can be unfolded on the ridge. At the same time, during the movement of the vehicle body 1, the soil on both sides of the ridge can be turned out and covered on the left and right sides of the ground film through the two covering plates 302; when adjusting the angle of the covering plate 302, any one of the worm screws 304 can be rotated. When the worm screw 304 is rotated, the two worm wheels 303 can be synchronously reversely driven under the drive of the worm screw 304. When the worm wheel 303 rotates, it can drive the installation shaft 301 and the covering plate 302 to adjust the angle; when installing the counterweight block 402, the counterweight block 402 can be lifted by hand and sleeved on the four second installation rods 401.
