Description

Technical Field

[0001] The utility model relates to the technical field of film covering devices, in particular to a film covering device for fruit tree planting. Background Art

[0002] In the process of fruit tree planting, film mulching technology is widely used to improve the growth efficiency of fruit trees and the quality of fruit. Film mulching can not only keep heat and moisture, promote soil microbial activity, and improve soil fertility, but also effectively prevent weed growth and reduce the occurrence of pests and diseases. When mulching fruit trees, a film mulching device is required.

[0003] In the existing technology, most fruit tree covering devices have complex structures, cumbersome operations, and are difficult to adapt to fruit trees of different heights and densities. In addition, some devices are prone to film breakage, wrinkling, or uneven coverage during the film covering process, which seriously affects the film covering effect. Therefore, we propose a fruit tree planting film covering device. Utility Model Content

[0004] The purpose of the utility model is to provide a film covering device for fruit tree planting to solve the problems raised in the above background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] The transmission gear is connected with the gear train of the driven gear and the transmission gear is connected with the gear train of the driven gear to form a gear. The transmission gear is connected with the gear train of the driven gear and the transmission gear is connected with the gear train of the driven gear to form a gear.

[0007] As a further solution of the present invention: a handrail is further provided on the frame.

[0008] As a further solution of the present invention: a plurality of limiting holes are evenly arranged on the slide rod, a threaded hole is penetrated through the slide plate, and a limiting screw rod for use with the limiting hole is provided in the threaded hole through a threaded connection.

[0009] As a further solution of the present invention: a return spring is further provided inside the installation cylinder.

[0010] As a further solution of the present invention: one end of the return spring is connected to the support rod, and the other end of the return spring is connected to the inner wall of the mounting tube.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0012] 1. The roller-driven pulley system converts the rotational kinetic energy of the roller when the device moves into the driving force for unwinding the film roll, realizing the automation of film covering. This not only reduces the burden of manual operation, but also significantly improves the efficiency of film covering, ensuring fast and uniform film covering of large areas of orchards. At the same time, under the action of the return spring, the continuous tension of the transmission belt is guaranteed, which improves the transmission efficiency and further ensures the stability and quality of the film covering.

[0013] 2. Under the action of the slide plate and the limiting screw, the film height can be flexibly adjusted according to the different heights and densities of the fruit trees to ensure that the film is close to the surface of the fruit trees, avoiding problems such as film breakage, wrinkling or uneven coverage that may occur in traditional film covering methods.

[0019] The following embodiments will be described in detail with reference to the accompanying drawings. Similar or identical parts are denoted by the same reference numerals in the drawings and descriptions. In actual applications, the shape, thickness, or height of each component may be enlarged or reduced.

Any obvious modifications or changes to the present invention do not depart from the spirit and scope of the present invention.

[0020] Example

[0021] See also Figures 1 to 4 In an embodiment of the utility model, a fruit tree planting film covering device includes a frame 1. A plurality of rollers 3 are evenly arranged on the bottom of the frame 1. Under the action of the rollers 3, the device can be driven to move as a whole, thereby facilitating the subsequent film covering work for the fruit trees. A handrail 2 is also provided on the frame 1. Under the action of the handrail 2, it is convenient for the staff to move the device.

[0022] The frame 1 is also evenly provided with a number of slide bars 4, on which a slide plate 5 is slidingly provided, and a fixed plate 6 is provided on the side wall of the slide plate 5. A mounting plate 10 is also rotatably provided on the fixing plate 6 through the mounting shaft 7, and a coating roll 11 is plugged into the mounting plate 10, which facilitates the disassembly and replacement of the coating roll 11, thereby ensuring the use efficiency of the device. A number of limiting holes 401 are also evenly provided on the slide bar 4, and a threaded hole is provided through the slide plate 5. A limiting screw 501 used in conjunction with the limiting hole 401 is provided in the threaded hole through a threaded connection. At this time, under the action of the limiting screw 501 and the limiting hole 401, the adjusted position of the slide plate 5 can be limited, thereby ensuring the coating quality.

[0023] A driving gear 8 is rotatably provided on the fixed plate 6, and a first pulley 12 is provided at the outer end of the rotating shaft of the driving gear 8. A driven gear 9 is also provided on the mounting shaft 7 through a key connection. The driven gear 9 and the driving gear 8 are meshed with each other. A second pulley 13 is provided on the rotating shaft of the intermediate roller 3 through a key connection. A mounting cylinder 14 is also provided on the frame 1 through a support plate. A support rod 15 is slidably provided on the mounting cylinder 14. A mounting bracket 16 is provided at the outer end of the support rod 15. A third pulley 17 is rotatably provided on the mounting bracket 16. The first pulley 12, the second pulley 13 and the third pulley 17 are connected by a transmission belt 18. At this time, when the device moves, the third pulley 17 and the second pulley 13 are connected. The pulley 13 and the transmission belt 18 drive the first pulley 12 to rotate, and then drive the driven gear 9 to rotate through the installation shaft 7 and the driving gear 8, so that the film roll 11 rotates, and then the film is unfolded, so as to better cover the fruit trees. A return spring 19 is also provided inside the installation cylinder 14. One end of the return spring 19 is connected to the support rod 15, and the other end of the return spring 19 is connected to the inner wall of the installation cylinder 14. At this time, under the action of the return spring 19, the third pulley 17 can always tension the transmission belt 18, thereby ensuring the transmission efficiency of the transmission belt 18, and at the same time can better adapt to the up and down movement of the slide plate 5, thereby ensuring the film covering quality of the fruit trees by the film covering device.

[0024] During actual use, the staff pushes the entire device through the handrail 2, and the roller 3 rolls on the ground, driving the entire device to move toward the fruit tree area. During the movement, the rotating shaft of the middle roller 3 is connected to the transmission belt 18 through the second pulley 13. As the roller rotates, the second pulley 13 also rotates. The other end of the transmission belt 18 is connected to the first pulley 12, and the first pulley 12 is installed at the outer end of the rotating shaft of the driving gear 8. When the second pulley 13 rotates, the first pulley 12 also starts to rotate through the transmission action of the transmission belt 18, thereby driving the driving gear 8 to rotate. The driving gear 8 and the driven gear 9 are meshed with each other. The driven gear 9 is installed on the mounting shaft 7 through a key connection. The mounting shaft 7 is fixedly connected to the mounting plate 10. The mounting plate 10 is plugged with a film roll 11. Therefore, when the driving gear 8 rotates, It will drive the driven gear 9 and the mounting shaft 7 to rotate synchronously, and then drive the covering roll 11 to unfold the film. In order to adjust the height of the film to adapt to fruit trees of different heights, the slide plate 5 can slide up and down on the slide bar 4, and the fixing plate 6 and the mounting plate 10 on the slide plate 5 move accordingly, and the position of the covering roll 11 is also adjusted accordingly. After the adjustment is completed, the limit screw 501 is rotated so that its end is inserted into the corresponding limit hole 401 to fix the position of the slide plate 5, thereby ensuring the stability of the covering process. The return spring 19 in the mounting cylinder 14 applies elastic force to the support rod 15, so that the third pulley 17 at the outer end of the support rod 15 can automatically adjust its position as the slide plate 5 moves up and down, keeping the transmission belt 18 in a tensioned state. In this way, no matter how the slide plate 5 moves, the transmission belt 18 can maintain high transmission efficiency, ensuring the smooth progress of the covering work.
