Description

Technical Field

[0001] The present invention relates to the technical field of agricultural equipment, and specifically relates to a device for covering soil on the surface of plastic film. Background Art

[0002] During the process of growing organic rice in the western and northern regions, herbicides cannot be used, and only manual weeding can be carried out. One person can only manage one or two mu of fields. When farmers grow organic rice, a large number of weeds will grow in the paddy fields. These weeds will affect the growth of rice.

[0003] Therefore, before growing rice, plastic film will be laid on the soil surface first. The plastic film covers the soil, and then water is irrigated, thereby preventing the growth of weeds. And covering the plastic film can increase temperature and keep warm, promote the growth of rice, conserve water and moisture, promote the growth of crops, and increase the yield.

[0004] However, problems still exist during the process of laying plastic film: the laid plastic film is very easy to be blown up and torn by strong winds, causing certain economic losses. In order to avoid damage to the laid plastic film, it is necessary to manually cover the soil horizontally on the surface of the plastic film again, which is time-consuming and laborious, with low work efficiency and high labor intensity.

[0019] The present invention provides a device for covering soil on the surface of a plastic film. It has the following beneficial effects:

[0020] 1. For this device for covering soil on the surface of a plastic film, a soil throwing block assembly is provided. The soil throwing block assembly is composed of a crawler and a bucket. The crawler extends above the plastic film, and the crawler drives the bucket to rotate, digging up and throwing the soil onto the plastic film, thereby preventing the plastic film from being blown up by strong winds, replacing manual operation, improving work efficiency, and reducing labor intensity.

[0021] 2. For this soil covering device on the surface of the plastic film, an airbag is set up outside the bucket, and a film is installed inside the bucket. There is an interlayer between the film and the bucket. By using an electric push rod to squeeze the airbag, the air in the airbag enters the interlayer, causing the film to bulge. This further provides an outward pushing force, enabling the soil in the bucket to be scattered farther and reducing the adhesion of wet soil to the inside of the bucket.

[0022] 3. For this soil covering device on the surface of the plastic film, the soil throwing component consists of a rotating shaft and a sleeve. A piston is slidably fitted inside the sleeve, and driving the sleeve to rotate achieves the purpose of taking soil. Through the cooperation of a push rod, a thick spring, a motor, and a steel wire, sufficient thrust is provided for the movement of the piston, achieving the effect of spraying the soil out of the sleeve.

[0023] 4. For this soil covering device on the surface of the plastic film, a separating piece is hinged at the soil taking end of the sleeve. The separating piece is used to prevent stones from entering the sleeve, thereby preventing the stones from being scattered on the plastic film and avoiding the plastic film being punctured by the stones, playing a role in protecting the plastic film.

Detailed Embodiment

[0032] The embodiment of the present invention provides a soil covering device on the surface of the plastic film. In the first embodiment, as Figure 1-2As shown in the figure: It is installed in front of the plastic film. It includes a soil block spreading component, which is installed at the bottom of the transplanter. The soil block spreading component is composed of multiple crawlers 1, two traction rollers 2 and multiple buckets 3. A bracket is welded at the bottom of the transplanter, and a driving motor is fixedly installed on the bracket. The driving motor is welded to the shaft end of the traction roller 2. Since this is a conventional technical means, no detailed description will be given. The multiple crawlers 1 are arranged at equal distances along the length of the traction roller 2, and the crawlers 1 are in transmission connection with the traction roller 2, which is a conventional technical means.

[0033] The multiple buckets 3 are fixedly installed on the crawlers 1 at equal distances. The crawler 1 is composed of multiple crawler plates, and the buckets 3 correspond to the crawler plates one by one. The buckets are installed on the crawler plates. The crawler 1 is arranged obliquely, and the upper end of the crawler 1 extends above the plastic film. During operation, the traction roller 2 drives the crawler 1 to rotate, and the bucket 3 moves along with the crawler 1. When the bucket 3 passes through the lowest part of the crawler 1, it digs up the soil. The bucket 3 transports the soil blocks to the topmost part, and the soil blocks fall out of the bucket 3 onto the plastic film, so as to achieve the purpose of covering soil on the plastic film.

[0034] An airbag 4 is fixedly installed on the outer side of the bucket 3. A film 31 is laid on the inner wall of the bucket 3. The edge of the film 31 is fixedly bonded to the edge of the inner wall of the bucket 3. A sandwich layer is formed between the film 31 and the inner wall of the bucket 3. The bucket 3 is provided with air holes 32, through which the airbag 4 is communicated with the sandwich layer. An electric push rod 41 is arranged in the airbag 4. One end of the electric push rod 41 is fixedly connected to the inner wall of the airbag 4, and the other end of the electric push rod 41 extends into the crawler 1. The electric push rod 41 is fixedly installed on the crawler plate 1.

[0035] The surface of the film 31 is coated with a waterproof coating. A plurality of positioning units are arranged in the crawler 1, and the positioning units always send signals to the signal receiving unit. The positioning units correspond to the buckets 3 one by one. A signal receiving unit is fixedly installed at the bottom of the transplanter. The positioning unit and the signal receiving unit are both conventional technical means, so the specific structures, models, etc. will not be described in detail.

[0036] A battery and a single-chip microcomputer are installed in each crawler plate 1. The battery and the single-chip microcomputer are electrically connected to the electric push rod 41. It is used to control the operation of the electric push rod 41. Since this is a conventional technical means, no detailed description will be given.

[0037] Working principle: When the bucket 3 moves to the highest point, the positioning unit corresponding to the bucket 3 is closest to the signal receiving unit. At this time, the electric push rod 41 contracts, and the electric push rod 41 contracts to squeeze the airbag 4. The air in the airbag 4 is pressed into the sandwich layer, so that the film 31 bulges, and thus the soil blocks in the bucket 3 are pushed out. Immediately afterwards, the electric push rod 41 resets, and the airbag 4 bulges to make the film 31 fit the inner wall of the bucket 3 again, so that the soil blocks are scattered farther. Further provide thrust to prevent the soil from sticking to the bucket 3 because it is wet.

[0038] Embodiment 2, as shown in the appendix Figures 3-5 As shown:

[0039] The soil scattering assembly can be composed of a rotating shaft 5 and multiple sleeves 7. The rear end of the sleeve 7 is the soil taking end. The sleeves 7 are grouped into three. The shaft of the rotating shaft 5 is fixedly installed with a base 51. The sleeve 7 and the base 51 are fixedly installed together. The front end of the sleeve 7 is slidably fitted with a push rod 71. A piston 72 is slidably fitted inside the sleeve 7. The rear end of the push rod 71 extends into the sleeve 7 and is welded to the piston 72. A thick spring 73 is welded to the front side of the piston 72. The front end of the thick spring 73 is welded to the inner wall of the push rod 71.

[0040] The bottom of the piston 72 is provided with a sliding cavity 721, the top of the inner wall of the sliding cavity 721 is welded with a thin spring 74, the lower end of the thin spring 74 is welded with a ball 75, and the inner wall of the sleeve 7 is provided with an embedding groove adapted to the thin spring 74. The embedding groove cooperates with the ball 75 to achieve a temporary positioning effect.

[0041] A motor 76 is fixedly mounted at the bottom of the sleeve 7, and a steel wire 77 is welded to the transmission shaft of the motor 76. The end of the steel wire 77 away from the motor 76 is welded to the front end of the push rod 71. The shaft end of the rotating shaft 5 is connected to the transmission shaft of the driving motor.

[0042] Working principle: The rotating shaft 5 drives the sleeve 7 to select. When the sleeve 7 moves to the bottom, the sleeve 7 digs up the soil. The soil entering the sleeve 7 pushes the piston 72 to move, and the push rod 71 extends from the sleeve 7, so that the ball 75 is embedded in the groove, and the large spring 73 is squeezed to the limit. When the sleeve 7 moves to the top, the motor 76 winds the steel wire 77 one circle, and the push rod 71 extends a short distance into the sleeve 7, so that the ball 75 is out of the groove, and then the motor 76 stops working. Because the ball 75 is pressed into the sliding cavity 721, under the action of elastic force, the large spring 73 expands and pushes the piston 72 to move, thereby achieving the purpose of ejecting the soil from the sleeve 7. In this way, the soil is thrown on the film.

[0043] A vertical support 6 is welded between the rotating shaft 5 and the sleeve 7. A slide groove is provided inside the support 6. A pressure sensing unit 1 62 is fixedly installed on the top of the inner wall of the slide groove. A pressure sensing unit 2 63 is fixedly installed on the bottom of the inner wall of the slide groove. A ball 64 is placed in the slide groove.

[0044] When the sleeve 7 moves to the lowest position, the ball 64 applies pressure to the pressure sensing unit 1 62, and when the ring 7 moves to the highest position, the ball 64 applies pressure to the pressure sensing unit 2 63. This is used to sense the position of the sleeve 7.

[0045] The support 61 is sleeved on one end of the support 6 away from the rotating shaft 5, and the support 61 is welded to the sleeve 7. The support 6 is provided with a screw 65 on the outside of the support 61, and the screw 65 is threadedly penetrated through the support 61 and the support 6. The support 6 also includes a base rod 52, one end of the base rod 52 is welded to the base 51, and the other end of the base rod 52 is welded to the sleeve 7. The base rod 52 and the support 6 are used to strengthen the firmness between the sleeve 7 and the base 51.

[0046] Example 3 is shown in the attached Figures 6-7 as follows:

[0047] A plurality of sleeves 7 in the same group are equally angularly distributed around the axis of the rotating shaft 5. A plurality of isolation sheets 8 are hinged to the lower edge of the soil-taking end of the sleeve 7. A notch 78 adapted to the isolation sheet 8 is provided at the upper edge of the soil-taking end of the sleeve 7. The isolation sheets 8 are arranged at equal distances. The above-mentioned isolation sheets 8 are parallel to the edge of the soil-taking end of the sleeve 7. Since the edge of the soil-taking end of the sleeve 7 is inclined, the upper end of the isolation sheet 8 is inclined. Such a setting is for when the sleeve 7 rotates following the rotating shaft 6, when the sleeve 7 is flipped to the uppermost position, the isolation sheet 8 naturally drops. The isolation sheet 8 will not hinder the soil from being scattered. When the sleeve 7 is flipped to the lowermost position (i.e., during the soil-digging process), the isolation sheet 8 intercepts at the opening of the soil-taking end of the sleeve 7. Thereby preventing stones in the soil from entering the sleeve 7. Avoiding stones from entering the sleeve 7, preventing the soil from carrying stones during the soil scattering process, and avoiding the stones from piercing the plastic film.

[0048] To sum up, for this plastic film surface soil covering device, a soil scattering component is set up. The soil scattering component is composed of a crawler 1 and a bucket 3. The crawler 1 extends above the plastic film. The crawler 1 drives the bucket 3 to rotate, digs up the soil and scatters it on the plastic film, so as to avoid the plastic film being blown up by the strong wind, replace manual operation, improve work efficiency and reduce labor intensity.

[0049] Moreover, an airbag 4 is set up outside the bucket 3, and a film 31 is installed inside the bucket 3. There is a sandwich layer between the film 31 and the bucket 3. The airbag 4 is squeezed by an electric push rod 41, so that the air in the airbag 4 enters the sandwich layer, thereby causing the film 31 to bulge. Further providing an outward pushing force, enabling the soil in the bucket 3 to be scattered farther, and reducing the adhesion of wet soil to the inside of the bucket 3.

[0050] Moreover, the soil scattering component is composed of a rotating shaft 5 and a sleeve 7. A piston 72 is slidably fitted inside the sleeve 7 to drive the sleeve 7 to rotate to achieve the purpose of taking soil. Through the cooperation of a push rod 71, a thick spring 73, a motor 76 and a steel wire 77, enough thrust is provided for the movement of the piston 72 to achieve the effect of spraying the soil out of the sleeve 7.

[0051] Moreover, an isolation sheet 8 is hinged to the soil-taking end of the sleeve 7, and the isolation sheet 8 is used to prevent stones from entering the sleeve 7, thereby preventing the stones from being scattered on the plastic film and avoiding the stones from piercing the plastic film, playing a role in protecting the plastic film.

[0052] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirits of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
