Technical Field

[0001] The invention relates to the technical field of ground film recovery, and in particular to a device for recovering ground film remaining on the soil surface. Background Art

[0002] Film mulching is an agricultural cultivation technology with multiple advantages such as warming and moisture retention, disease and insect resistance, moisture retention, heat preservation, insect resistance, weed suppression, etc. It has greatly improved the yield and quality of crops, made outstanding contributions to agricultural production increase and farmers' income increase, and is beneficial to crop growth and development, and increases crop yield. It is widely used in agriculture, textile and other fields, but the residual film in the soil has serious harm to the soil, crops, ecological environment, human health, agricultural costs and landscape. Its negative impact needs to be reduced through recycling and environmental protection measures. When recycling the film, it is often necessary to use a device for recovering the residual film on the soil surface.

[0003] The existing device for recovering residual film on the soil surface often uses electrostatic adsorption to achieve a better picking effect when picking up the film with a film picking roller. However, when the scraper subsequently scrapes the film on the film picking roller, it is difficult to scrape it off due to the adsorption effect on the film picking roller, and multiple scraping operations are required to scrape the film off, which reduces the efficiency of the device in recovering the film.

One end of the collecting pipe 9 passes through the bottom wall of the vehicle body 1 and extends to the inside of the collecting box 2. A negative pressure fan 10 is fixedly installed on the surface of the collecting pipe 9. The negative pressure fan 10 is fixedly connected to the bottom of the vehicle body 1. A filter hole 17 is opened at the bottom of the collecting box 2. The film picking mechanism 3 is started to pick up the ground film on the surface of the soil. The electrostatic conduction mechanism 4 can pass static electricity on the film picking plate 34 being picked up, so that the film picking plate 34 can be negatively charged, and then the ground film can be adsorbed, which is convenient for adsorbing the ground film firmly. When the plate 7 unloads the ground film, the negative charge remaining on the film picking plate 34 is guided to the ground through the electrostatic drainage mechanism 5, so that the picking plate no longer carries negative charge, that is, the film picking plate 34 no longer has an adsorption effect, so that it is convenient for the scraper 7 to scrape off the ground film, and the scraped ground film is crushed by the crushing device 8 and enters the processing box 6. The filter holes 17 can be used to filter out small particles of soil in the ground film, and the negative pressure fan 10 is started to work. The negative pressure fan 10 forms a negative pressure inside the collection pipe 9, so that the ground film is crushed. The ground film enters the interior of the collecting box 2 through the collecting pipe 9, and enters the bottom side of the collecting box 2 through the material guide plate 11, and the hydraulic rod 13 is driven downward by the hydraulic cylinder 12, and the hydraulic rod 13 drives the pressing plate 14 to move downward, and the downward moving pressing plate 14 can compact the fluffy ground film, thereby increasing the storage space inside the collecting box 2. The collection situation inside the collecting box 2 can be observed through the observation window 15. When it is found that the ground film in the collecting box 2 is full, the ground film inside the collecting box 2 can be taken out by opening the door panel 16.

[0023] Among them, the film picking mechanism 3 includes a connecting plate 31, the number of the connecting plates 31 is set to two, the two connecting plates 31 are fixedly connected to the same side of the vehicle body 1, a rotating shaft 32 is commonly connected to the two connecting plates 31, a roller 33 is fixedly connected to the surface of the rotating shaft 32, a film picking plate 34 is fixedly connected to the surface of the roller 33, and a plurality of groups of film picking plates 34 are provided, and a conductive plate 35 is commonly fixedly connected between each group of film picking plates 34.

[0024] Among them, a power component 36 is fixedly installed on the surface of one of the connecting plates 31, and the output end of the power component 36 is fixedly connected to one end of the rotating shaft 32. First, the power component 36 is started to drive the rotating shaft 32 to rotate, and the rotating shaft 32 drives the roller shaft 33 to rotate, so that the film picking plate 34 on the roller shaft 33 rotates. The rotating film picking plate 34 can pick up the ground film remaining on the soil surface, thereby achieving the purpose of picking up the ground film.

[0025] The electrostatic conduction mechanism 4 includes a first conductive sheet 41, which is fixedly connected to one end of the conductive plate 35, and a surface of one of the connecting plates 31 is fixedly connected to an electrostatic generator 42, and an output end of the electrostatic generator 42 is electrically connected to a first wire 43, and an output end of the first wire 43 is fixedly connected to a first curved plate 44, which is fixedly installed on the surface of the connecting plate 31, and one end of the first curved plate 44 is fixedly connected to a first introduction plate 45, and the front side of the first conductive sheet 41 can be in contact with the back side of the first curved plate 44, and the electrostatic generator 42 generates Static electricity is generated, that is, negative charges are generated, and the negative charges are conducted to the first curved plate 44 through the first wire 43, and the film picking plate 34 to pick up the ground film is rotated to one side of the first curved plate 44, and the first conductive sheet 41 and the first curved plate 44 are made to slide and contact each other through the first introduction plate 45, so that the negative charges on the first curved plate 44 enter the conductive plate 35 through the first conductive sheet 41, and finally enter the film picking plate 34 through the conductive plate 35, so that the film picking plate 34 carries negative charges, which can produce an adsorption effect on the ground film, and then can firmly pick up the ground film.

[0026] The electrostatic drainage mechanism 5 includes a second conductive sheet 51, which is fixedly connected to the other end of the conductive plate 35. A second curved plate 52 is fixedly connected to the surface of another connecting plate 31. The second conductive sheet 51 can be in contact with the second curved plate 52. One end of the second curved plate 52 is fixedly connected to a second introduction plate 53. When the electrostatic drainage mechanism 5 is used to conduct electrostatic drainage on the film pickup plate 34 that is about to or already needs to be scraped by the scraper 7, the first conductive sheet 41 on the film pickup plate 34 is separated from the first curved plate 44, so that no more negative charges will continue to enter the conductive sheet. Similarly, when the rotation continues, the film picking plate 34 that is about to be unloaded by the scraper 7 rotates to one side of the second curved plate 52. At this time, the second conductive sheet 51 rotates and contacts with the second curved plate 52, so that the negative charge remaining on the conductive plate 35 enters the second curved plate 52 through the second conductive sheet 51, and then the negative charge enters the conductive counterweight ball 57 through the second wire 56. Since the counterweight ball 57 is in contact with the ground, the negative charge is conducted to the ground through the counterweight ball 57. As a result, there is no negative charge on the film picking plate 34 at this time. At this time, the film picking plate 34 no longer has adsorption, so it is easier to be scraped off the ground film by the scraper 7.

[0027] Among them, a positioning tube 54 is fixedly connected to the bottom of the second arc-shaped plate 52, a temporary collection tube 55 is fixedly connected to the surface of the positioning tube 54, a second wire 56 is arranged inside the positioning tube 54, one end of the second wire 56 is fixedly connected to the bottom of the second arc-shaped plate 52, and the other end of the second wire 56 extends to the bottom side of the positioning tube 54 and is fixedly connected to a counterweight ball 57, the counterweight ball 57 is conductive, and the conductive counterweight ball 57 can ensure that the second wire 56 is in contact with the ground and negative charges are introduced into the earth. The second wire 56 collected in the temporary collection tube 55 can be conveniently adjusted in length for use at different heights of the ground, thereby improving the practicability of the device, and the positioning tube 54 can be used to conveniently straighten the second wire 56 to prevent the second wire 56 from being entangled.

[0028] Among them, the front shapes of the first arc plate 44 and the second arc plate 52 are both arranged concentrically with the rotating shaft 32, and the first arc plate 44 and the second arc plate 52 are located at complementary positions in the concentric circles. The first arc plate 44 and the second arc plate 52 are both made of conductive materials, which can facilitate the alternating contact between the first arc plate 44 and the second arc plate 52 when the first conductive sheet 41 and the second conductive sheet 51 rotate, that is, when static electricity is generated, the static electricity on the film pickup plate 34 will not be conducted away, and when the static electricity needs to be conducted away, the static electricity will no longer continue to be input into the film pickup plate 34.

[0029] Among them, the crushing device 8 includes a transmission wheel assembly 81, a power unit 82 is fixedly installed on the front of the transmission wheel assembly 81, and a crushing roller 83 is rotatably connected inside the processing box 6. The output end of the crushing roller 83 and the transmission wheel assembly 81 are fixedly connected to one end of the crushing roller 83. The crushing roller 83 is located at the input port of the processing box 6. The pulley assembly is started by the power unit 82 to work. The rotation of the pulley assembly drives the two crushing rollers 83 inside the processing box 6 to rotate in opposite directions, so that the rotating crushing roller 83 can crush the scraped ground film, which reduces the subsequent processing work of recovering the ground film, and facilitates the subsequent collection pipe 9 to suck the ground film into the collection box 2, thereby improving the working efficiency of the device.

[0030] Among them, a material guide plate 11 is fixedly connected to one side of the interior of the collecting box 2, and the top of the material guide plate 11 is on the same inclined plane as the top of the collecting pipe 9. A hydraulic cylinder 12 is fixedly installed on the top of the collecting box 2, and the output end of the hydraulic cylinder 12 is transmission-connected to a hydraulic rod 13, and the bottom end of the hydraulic rod 13 is fixedly connected to a pressing plate 14. The guide plate 11 can conveniently guide the ground film to the bottom of the pressing plate 14, so that the pressing plate 14 can compact it conveniently. The hydraulic rod 13 is driven downward by the hydraulic cylinder 12, and the hydraulic rod 13 drives the pressing plate 14 to move downward. The downward moving pressing plate 14 can compact the fluffy ground film, thereby increasing the storage space inside the collecting box 2. The collection situation inside the collecting box 2 can be observed through the observation window 15. When it is found that the ground film in the collecting box 2 is full, the ground film inside the collecting box 2 can be taken out by opening the door panel 16.

[0031] Among them, an observation window 15 is fixedly connected to the front of the collection box 2, and a door panel 16 is rotatably connected to the bottom of one side of the collection box 2. The collection situation inside the collection box 2 can be easily checked through the observation window 15, so that the staff can take out the compacted ground film in time.

[0032] During work, the staff drives the vehicle body 1 to the area where the ground film needs to be recovered, and then starts the film picking mechanism 3 to work. During the driving process of the vehicle body 1, the rotating film picking mechanism 3 can pick up the ground film remaining on the soil surface. In the stage of picking up the ground film, the electrostatic conduction mechanism 4 can pass static electricity to the film picking plate 34 being picked up, so that the film picking plate 34 is charged, and the ground film is made of polyethylene and polyvinyl chloride, which is a dielectric. The electrons in the dielectric molecules are different from conductors and cannot move freely, so that the ground film is not charged, and then the charged film picking plate 34 can absorb the uncharged ground film to prevent the ground film from falling during the picking process. The film picking plate 34 close to the scraper 7 drains the static electricity on the film picking plate 34 through the electrostatic drainage mechanism 5, so that the film picking plate 34 no longer carries a charge, and then the scraper 7 can more conveniently collect the picked up ground film. The scraped ground film enters the processing box 6 along the inclined direction of the scraper 7. Before entering the processing box 6, the collected ground film is crushed by the crushing device 8. The small particles of soil in the ground film can be filtered out through the filter holes 17 in the processing box 6. The negative pressure fan 10 is started to work. The negative pressure fan 10 forms a negative pressure inside the collection pipe 9, so that the crushed ground film enters the collection box 2 through the collection pipe 9. The ground film enters the bottom side of the collection box 2 through the guide plate 11, and the hydraulic rod 13 is driven downward by the hydraulic cylinder 12. The hydraulic rod 13 drives the pressing plate 14 to move downward. The downward moving pressing plate 14 can compact the fluffy ground film, thereby increasing the storage space inside the collection box 2. The collection situation inside the collection box 2 can be observed through the observation window 15. When it is found that the ground film in the collection box 2 is full, the ground film inside the collection box 2 is taken out by opening the door panel 16; When picking up the ground film by the film picking mechanism 3, firstly, the power member 36 is started to drive the rotating shaft 32 to rotate, and the rotating shaft 32 drives the roller shaft 33 to rotate, so that the film picking plate 34 on the roller shaft 33 rotates, and the rotating film picking plate 34 can pick up the ground film remaining on the soil surface, so as to achieve the purpose of picking up the ground film; When static electricity is applied to the film picking plate 34 that is picking up or has just picked up the ground film through the static electricity conduction mechanism 4, static electricity is generated through the static electricity generator 42, and the static electricity is conducted to the first curved plate 44 through the first wire 43, the film picking plate 34 that is to pick up the ground film is rotated to one side of the first curved plate 44, and the first conductive sheet 41 and the first curved plate 44 are brought into sliding contact with each other through the first introduction plate 45, so that the negative charge on the first curved plate 44 enters the conductive plate 35 through the first conductive sheet 41, and finally enters the film picking plate 34 through the conductive plate 35, so that the film picking plate 34 carries negative charge, which can produce an adsorption effect on the ground film, and thus can firmly pick up the ground film; When the electrostatic drainage mechanism 5 is used to conduct electrostatic drainage on the film picking plate 34 that is about to or already needs to be scraped by the scraper 7, the first conductive sheet 41 on the film picking plate 34 is separated from the first curved plate 44, so that no more negative charges will enter the conductive sheet. Similarly, when the film picking plate 34 that is about to be unloaded by the scraper 7 is rotated to the side of the second curved plate 52, at this time, the second conductive sheet 51 and the second curved plate 52 are in rotational contact, so that the negative charges remaining on the conductive plate 35 enter the second curved plate 52 through the second conductive sheet 51, and then the negative charges enter the conductive counterweight ball 57 through the second wire 56. Since the counterweight ball 57 is in contact with the ground, the negative charges are conducted to the ground through the counterweight ball 57, and then there is no negative charge on the film picking plate 34 at this time, and the film picking plate 34 at this time no longer has adsorption, so that it is easier to be scraped off the ground film by the scraper 7; When the picked-up ground film is crushed by the crushing device 8, the pulley assembly is first started by the power unit 82 to work. The rotation of the pulley assembly drives the two crushing rollers 83 inside the processing box 6 to rotate towards each other, so that the rotating crushing rollers 83 can crush the scraped ground film, which reduces the subsequent processing work of recovering the ground film and facilitates the subsequent collection pipe 9 to suck the ground film into the collection box 2, thereby improving the working efficiency of the device.
