Description

Technical Field

[0001] The invention relates to the technical field of ground film laying and recycling, and in particular to a ground film laying and recycling integrated machine. Background Art

[0002] In agricultural production, mulching technology is widely used. Mulch can effectively retain soil moisture, increase soil temperature, inhibit weed growth, etc., which has a positive impact on the growth and yield of crops. However, with the increasing use of mulch, the problem of mulch residue is becoming more and more serious. Traditional mulch recycling methods are often inefficient and require a lot of manpower and time.

In this article, "one" not only means "only one", but also means "more than one", and "several" includes "two" and "more than two".

[0049] In this document, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0050] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0051] Reference Figure 1~Figure 4 , is an embodiment of the present invention, and proposes a ground film laying and recycling integrated machine, including: a frame 1; a film laying mechanism 2 is arranged in the middle of the frame 1, and the film laying mechanism 2 is used to lay ground film on the ground; there are a plurality of film pulling hooks 6, and the plurality of film pulling hooks 6 are arranged at intervals at the front end of the frame 1, and the film pulling hooks 6 are used to destroy the old ground film; a film collecting rod 7 is rotatably arranged at the bottom of the frame 1, and the film collecting rod 7 is located between the film pulling hook 6 and the film laying mechanism 2, and the film collecting rod 7 has a winding part 71, each winding part 71 is located between adjacent film pulling hooks 6, and the winding part 71 is used to wind the broken ground film.

[0052] In the above scheme, the frame 1 is welded from metal square tubes, and the overall structure is a rectangular frame with sufficient strength and stability. The film-pulling hooks 6 are evenly spaced and installed at the front end of the frame 1. The film-pulling hooks 6 are curved metal hooks with sharp hook tips and a certain curvature, which are convenient for inserting under the old ground film. Each winding portion 71 of the film-collecting rod 7 is located at the quality inspection of the adjacent film-pulling hooks 6 to ensure that the broken ground film can be effectively collected.

[0053] Working process: When the machine moves forward, the film pulling hook 6 is inserted under the old ground film in the soil. As the machine moves, the old ground film is pulled up and broken into pieces. When the broken ground film contacts the film collecting rod 7, due to the barb structure of the winding part 71, the ground film fragments are wound around the winding part 71, thereby realizing the preliminary recovery of the ground film fragments. At the same time, the film laying mechanism 2 in the middle of the frame 1 carries out the laying operation of the new ground film. The integrated operation of ground film laying and recycling is realized, which improves agricultural production efficiency, reduces the investment cost of equipment, avoids the waste of time and manpower caused by traditional separate operations, helps to solve the problem of residual ground film, and protects the soil environment and the growth environment of crops.

[0054] Furthermore, it also includes a guide scraper 61, which is arranged between adjacent film pulling hooks 6 and is used to shovel up the broken ground film.

[0055] In the above scheme, the front end of the guide scraper 61 is shovel-shaped. Between adjacent film-pulling hooks 6, the guide scraper 61 is fixed between the curved sections of adjacent film-pulling hooks 6 by bolts or welding, and the shovel-shaped front end of the guide scraper 61 contacts the ground.

[0056] Working process: After the film-pulling hook 6 destroys the old ground film, the guide scraper 61 moves forward with the machine, and the shovel-shaped front end of the guide scraper 61 shovels the broken ground film, making it easier for the ground film to be wound and collected by the film collecting rod 7. This improves the collection efficiency of the broken ground film, reduces the residual ground film on the ground, makes the recycling process smoother, and reduces the risk of incomplete recycling caused by scattered ground film.

[0057] Furthermore, it also includes: a first extension frame 103 is detachably arranged on the front of the frame 1, a plurality of film pulling hooks 6 are swingably arranged on the first extension frame 103, a film collecting rod 7 is rotatably arranged on the first extension frame 103, and the film collecting rod 7 is located above the guide scraper 61.

[0058] In the above scheme, the first extension frame 103 is detachably connected to the front of the frame 1 through a slot and a bolt. The film-pulling hook 6 is installed on the first extension frame 103 through a hinge, and the film-pulling hook 6 can swing within a certain range to adapt to the position change of the old ground film under different terrains. The film-collecting rod 7 is installed on the longitudinal beam in the middle of the first extension frame 103 through a bearing, and is located above the guide scraper 61 to facilitate winding of the ground film. A guide positioning wheel 5 is also provided at the front end of the first extension frame 103.

[0059] Working process: When the machine is running, the first extension frame 103 moves forward with the random frame 1, the film pulling hook 6 swings at the front end to insert the old ground film and destroy it, the guide scraper 61 scoops up the broken ground film, and the film collecting rod 7 wraps and collects the scooped ground film. The adaptability of the equipment to complex terrain is improved, ensuring that the ground film recycling operation can be effectively carried out in farmlands with different undulating terrains. At the same time, the detachable structure facilitates the maintenance and management of the equipment and improves the practicality of the overall equipment.

[0060] Furthermore, the film collecting rod 7 has a telescopic section 7032 and also includes: a plurality of barb strips 12 , which are hingedly arranged at intervals on the circumference of the outer wall of the telescopic section 7032 , and the plurality of barb strips 12 form a winding portion 71 .

[0061] In the above scheme, the fixed section 7031 of the film collecting rod 7 is a relatively thick metal tube, the telescopic section 7032 is a relatively thin metal rod nested in the fixed section 7031 and slidably telescopic, and a spring is arranged in the fixed section 7031, and the spring is used to support the telescopic section 7032 to extend out of the fixed section 7031. The barb strip 12 is made of metal material, and one end is connected to the outer wall of the telescopic section 7032 with a hinge. A plurality of barb strips 12 are evenly spaced and distributed on the circumference of the outer wall of the telescopic section 7032, and the barb strips 12 can swing freely within a certain range.

[0062] Working process: When the film collecting rod 7 rotates, the barb strip 12 rotates with the telescopic section 7032. When encountering broken ground film, the barb strip 12 can easily hook the ground film due to its barb structure and wrap the ground film with the rotation. The barb strip 12 enhances the ability of the film collecting rod 7 to grab and wrap broken ground film, effectively reducing the residual ground film and improving the recycling quality.

[0063] Furthermore, the film collecting rod 7 also has a fixed section 7031; it also includes: a rotating shaft 701 rotatably set on the first extension frame 103; there are a plurality of turntables 702, and the plurality of turntables 702 are spaced apart on the rotating shaft 701, each turntable 702 is located between two adjacent film pulling hooks 6, and the turntable 702 has a plurality of mounting grooves 7021 on its circumference; the fixed section 7031 is arranged in the mounting groove 7021, the telescopic section 7032 extends out of the mounting groove 7021 and the telescopic section 7032 is located between the two film pulling hooks 6, and the film collecting rod 7 has a butt end 7033, and after the rotating shaft 701 drives the film collecting rod 7 to rotate, the butt end 7033 slides and butts against the guide scraper 61.

[0064] In the above scheme, the rotating shaft 701 is installed on the first extension frame 103 through the bearing seat and can rotate freely. The rotating disks 702 are installed on the rotating shaft 701 at intervals, and a plurality of mounting grooves 7021 are evenly distributed on the circumference of each rotating disk 702. The fixed section 7031 of the film collecting rod 7 is inserted into the mounting groove 7021 and fixed by bolts, and the telescopic section 7032 extends out of the mounting groove 7021. The abutting end 7033 of the telescopic section 7032 is a circular slider structure. When the rotating shaft 701 rotates, the rotating disk 702 and the film collecting rod 7 are driven to rotate together, so that the abutting end 7033 can slide and abut against the upper surface of the guide scraper 61.

[0065] Working process: When recycling the ground film, the rotating shaft 701 rotates, driving the rotating disk 702 and the film collecting rod 7 to rotate. When the abutting end 7033 of the film collecting rod 7 abuts against the guide scraper 61, the barb strips 12 will wrap around the ground film as it rotates. The working efficiency and recycling quality of the film collecting rod 7 are improved. Through the linkage with the guide scraper 61, the residual broken ground film in the ground film recycling process is further reduced, which is beneficial to the subsequent treatment and reuse.

[0066] Furthermore, it also includes: a collecting box 4 is arranged on the frame 1, and a plurality of through grooves 41 are opened on the bottom and side walls of the collecting box 4, each film collecting rod 7 corresponds to a through groove 41, and after the turntable 702 rotates, the film collecting rod 7 slides into the through groove 41; a filter plate 9 is arranged in the middle of the inner side of the collecting box 4, and the filter plate 9 has a plurality of filter holes 901; a negative pressure member 8 is arranged on the collecting box 4, and the negative pressure member 8 is used to absorb the ground film fallen from the barbed strip 12 into the collecting box 4.

[0067] In the above scheme, the collecting box 4 is made of welded metal plates in the shape of a cuboid and is installed above the frame 1. A number of convex strips 10 are arranged at intervals on the inner wall of the collecting box 4. Through grooves 41 are evenly provided on the bottom and side walls of the collecting box 4. The size of the through grooves 41 is adapted to the outer diameter of the film collecting rod 7 to ensure that the film collecting rod 7 can pass smoothly. The filter plate 9 is a metal mesh plate, which is installed in the middle of the inner side of the collecting box 4. The filter holes 901 thereof are convenient for ventilation and passing small film fragments. The negative pressure member 8 is installed on the top of the collecting box 4. The air outlet of the negative pressure member 8 is connected to the inside of the collecting box 4, and the air outlet leads to the outside. The position of the collecting box 4 is convenient for receiving the film recovered by the film collecting rod 7. The cooperation between the through grooves 41 and the film collecting rod 7 realizes the transfer of the film.

[0068] Furthermore, an inclined slide 11 is provided in the collecting box 4; it also includes: a sleeve 13 is slidably mounted on the film collecting rod 7, and the sleeve 13 is located outside the mounting groove 7021; the sleeve 13 slides against the inclined slide 11, and after the sleeve 13 slides along the inclined slide 11, the sleeve 13 moves along the axial direction of the film collecting rod 7, and the sleeve 13 is used to push out the ground film wrapped on the barbed strip 12; one end of the tension spring 14 is arranged on the outer wall of the film collecting rod 7, and the other end is arranged on the side wall of the sleeve 13, and the tension spring 14 is used to provide a force for resetting the sleeve 13.

[0069] In the above scheme, the inclined slide 11 is made of a metal plate, with an inclination angle of 45 degrees, and is installed on the inner wall of the collection box 4. The sleeve 13 is a metal cylinder, and the sleeve 13 is slidably mounted on the film collecting rod 7. The sleeve 13 is located outside the installation groove 7021, and the end face of the sleeve 13 is slidably abutted against the inclined slide 11. One end of the tension spring 14 is hung on a hook on the outer wall of the film collecting rod 7, and the other end is hung on a hook on the side wall of the sleeve 13. When the tension spring 14 is in a natural state, the sleeve 13 is located on the side away from the barb strip 12.

[0070] Working process: When the film collecting rod 7 moves toward the through slot 41 of the collection box 4 driven by the rotating disk 702, the sleeve 13 moves upward along the axis direction of the film collecting rod 7 under the action of the inclined slide 11, pushing out the ground film wrapped on the barb strip 12, so that the ground film fragments are more easily sucked into the collection box 4 by the negative pressure member 8. When the film collecting rod 7 leaves the through slot 41, the sleeve 13 is reset to the initial position under the action of the tension spring 14. This effectively improves the efficiency of ground film falling off the film collecting rod 7 and being collected by the collection box 4, reduces the residual ground film on the film collecting rod 7, further improves the recycling effect of the entire equipment, and ensures the continuity and stability of the recycling operation.

[0071] Furthermore, it also includes: a covering cylinder 3; a tail frame 102 detachably arranged at the rear of the frame 1, the covering cylinder 3 is rotatably arranged on the tail frame 102, and the tail frame 102 has an adjusting part 1021, and the adjusting part 1021 is used to adjust the horizontal distance between the tail frame 102 and the frame 1.

[0072] In the above scheme, the soil covering cylinder 3 is made of a metal cylinder, and the soil inlets 301 at both ends are miniature trumpet-shaped openings for receiving soil. The soil outlets 302 on the circumferential side walls are evenly distributed and are in the shape of long strips, and their size and number are determined according to the soil covering requirements. The tail frame 102 is welded from metal square tubes and is detachably mounted on the tail of the frame 1 through slots and bolts. The detachable connection between the soil covering cylinder 3 and the tail frame 102 is convenient for installation and maintenance, and the opening of the soil covering cylinder 3 is conducive to the entry and exit of soil. The adjustment part 1021 can flexibly adjust the relative position of the soil covering cylinder 3 and the frame 1 to adapt to different soil covering width and thickness requirements.

[0073] Working process: After laying a new ground film, the soil collecting plate 16 on the tail frame 102 collects the soil and sends it to the soil inlet 301 of the soil covering cylinder 3 during the machine's travel. The soil is brought to the soil outlet 302 in the soil covering cylinder 3 as the cylinder rotates, and then evenly covers both sides of the newly laid ground film. Automatic soil covering after laying the ground film is realized, the degree of automation of agricultural production is improved, the workload and labor intensity of manual soil covering are reduced, and the adjustable structure can meet the different soil covering requirements of different crops, which is conducive to improving the planting quality and yield of crops.

[0074] Furthermore, the soil covering cylinder 3 has soil inlets 301 at both ends, and a soil outlet 302 on the circumferential side wall thereof, and further includes: a soil collecting plate 16 rotatably arranged on the tail frame 102, and the soil collecting plate 16 is used to introduce soil into the soil inlet 301; a plurality of anti-sliding blocks 15, and the plurality of anti-sliding blocks 15 are arranged at intervals on the soil covering cylinder 3, and the anti-sliding blocks 15 are used to prevent the soil covering cylinder 3 from slipping.

[0075] In the above scheme, the soil collecting plate 16 is made of a metal disc, which is mounted on the tail frame 102 through a bearing and can rotate with the frame 1 when in contact with the ground. The anti-sliding block 15 is a block structure made of rubber material, which is evenly pasted on the outer wall of the soil covering cylinder 3 at intervals, and has a certain pattern on its surface to increase the friction with the ground.

[0076] Working process: When the machine moves forward, the soil collecting plate 16 is inserted into the soil. As the machine moves and the soil collecting plate 16 rotates, the soil is scooped up and sent to the soil inlet 301 of the soil covering cylinder 3. At the same time, when the soil covering cylinder 3 rotates to cover the soil, the anti-sliding block 15 is in close contact with the ground to prevent the soil covering cylinder 3 from slipping due to insufficient friction with the ground, thereby ensuring the uniformity and stability of the soil covering. The efficiency and quality of the soil covering operation are improved, ensuring that the soil can be accurately covered on both sides of the ground film. The existence of the anti-sliding block 15 reduces the problem of uneven or discontinuous soil covering caused by slipping, which is conducive to the creation of a growing environment for crops.

[0077] Furthermore, the film laying mechanism 2 includes: a second extension frame 101, which is detachably arranged at the lower middle part of the frame 1; a placement roller 201, which is arranged at the top of the frame 1, and the placement roller 201 is used to place new ground film; a guide roller 202, which is rotatably arranged on the second extension frame 101, and the guide roller 202 is used to guide the ground film close to the ground; a film pressing plate 203, which is rotatably arranged on the second extension frame 101 and is located on both sides of the guide roller 202, and the film pressing plate 203 is used to press both sides of the ground film into the soil; a covering plate 204, which is rotatably arranged on the frame 1, and the covering plate 204 is used to push soil to both sides of the ground film.

[0078] In the above scheme, the second extension frame 101 is made of a metal square tube and is detachably mounted at the lower middle part of the frame 1 through a slot and bolts. The placement roller 201 is a metal roller, which is mounted on the two side brackets at the top of the frame 1 through a bearing, and can place a whole roll of new ground film. The guide roller 202 is a small-diameter metal roller, which is rotatably mounted at the front end of the second extension frame 101 through a bearing. The guide roller 202 can guide the ground film to smoothly extend downward from the placement roller 201 to the ground. The film pressing plate 203 is a circular metal plate, which is mounted on the second extension frame 101 through a bearing and is located on both sides of the guide roller 202. Its edge has a certain curvature, and when it contacts the ground, it can press the two sides of the ground film into the soil.

[0079] Working process: First, place the new mulch roll on the placing roller 201, and one end of the mulch wraps around the guide roller 202 in turn. As the machine moves forward, the pressing disc 203 presses both sides of the mulch into the soil to initially fix it, and then the covering disc 204 pushes the soil to both sides of the mulch to complete the laying and covering of the mulch.
