Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a small agricultural film laying machine. Background Technology

[0002] In agricultural production, mulching can increase soil temperature, retain water and fertilizer, suppress weed growth, and reduce pests and diseases. However, for ordinary farmers, purchasing large-scale mulching equipment is too expensive and not used frequently, making it very uneconomical. Therefore, small agricultural mulching machines are needed to meet the farming needs of ordinary farmers.

[0003] A prior patent with authorization announcement number CN217905436U discloses a hand-operated film covering machine, comprising: a frame, of which two are arranged in a mirror image on both sides; a rear connector and a front connector, both of which are slidably connected between the two frames; a rear tillage plow connecting frame and a front tillage plow connecting frame are provided on the outer side of the frame, and a tillage plow body is connected to both the rear tillage plow connecting frame and the front tillage plow connecting frame; a traveling wheel connecting piece is provided on the outer side of the frame and located between the rear tillage plow connecting frame and the front tillage plow connecting frame; a support frame is slidably connected to the inner side of the traveling wheel connecting piece, and a locking screw is provided between the support frame and the traveling wheel connecting piece; and rollers are provided at the bottom of the support frame. This solves the problems of traditional hand-operated film covering machines having a simple structure, being difficult to adjust when used in areas with different ridge widths and heights, and also being difficult to install the film cylinder. However, the mulching device only has two rollers pressing on both sides of the mulch film, which cannot guarantee that the middle of the mulch film will adhere to the soil ridge. During the mulching process, the middle of the mulch film may arch due to air injection, which will cause the sides of the mulch film to fold inward. As a result, the soil turned up by the tillage plow will not press down the sides of the mulch film enough, or even not press down the sides of the mulch film at all. Utility Model Content

Detailed Implementation

[0035] To make the technical problems, technical solutions and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0036] like Figure 1As shown, this embodiment discloses a small agricultural film-laying machine, including a frame 1. An adjustable covering plow 2 is installed on the lower rear side of the frame 1. A pressing roller 3 is installed on the lower middle of the frame 1. A furrowing plow 4 is installed on the lower front side of the frame 1. A film-film tube installation mechanism 6 is installed at the front end of the frame 1, located in front of the furrowing plow 4. A film-pressing mechanism 5 is installed between the pressing roller 3 and the furrowing plow 4. The film-pressing mechanism 5 includes a main pressing rod 5-1 and side pressing rods 5-2. The side pressing rods 5-2 are located on both sides of the main pressing rod 5-1. The lower end faces of both the main pressing rod 5-1 and the side pressing rods 5-2 are arc-shaped. The main pressing rod 5-1 and the side pressing rods 5-2 are respectively connected to a crossbeam 5-4 through several connecting rods 5-3. The crossbeam 5-4 is installed on the frame 1. A load-bearing basket 7 is installed on the frame 1. A handle 8 is installed on the front side of the frame 1. During operation, the plastic film tube is installed in the plastic film tube installation mechanism 6. First, one end of the plastic film is pulled out and pressed down with soil. By pulling the handle 8, the frame 1 moves forward. The trenching plow 4 has an arc-shaped concave blade structure, and the arc-shaped concave surfaces of the two trenching plows 4 are set facing each other. The blades of the trenching plow 4 are set at an angle to the forward direction of the frame 1, that is, the rear side of the blade is folded inward and the front side of the blade is spread outward. When the frame 1 moves forward, the trenching plow 4 digs up the soil and gathers the turned soil inward to form a soil mound. The plastic film is pulled out when the frame 1 moves forward. At the same time, the main pressure rod 5-1 and the side pressure rod 5-2 press the plastic film onto the soil mound, ensuring that the middle of the plastic film is in contact with the soil mound. The edge pressing roller 3 presses on both sides of the plastic film, while the covering plow 2 turns up the soil inward to press down on both sides of the plastic film.

[0037] At the same time, a load can be placed in the load-bearing basket 7 to maintain the stability of the frame 1.

[0038] like Figure 2 As shown, the covering plow 2 includes a plow blade 2-1, which is fixedly connected to the covering plow handle 2-2. The covering plow handle 2-2 is slidably mounted on a fixed sleeve 2-3, which is fixedly mounted on the frame 1. The covering plow handle 2-2 has several locking holes 2-2-1, and the fixed sleeve 2-3 has pre-drilled bolt holes. A first bolt assembly 2-3-1 is installed in the pre-drilled bolt holes of the fixed sleeve 2-3. The locking holes 2-2-1 and the fixed sleeve 2-3 are connected via the first bolt assembly 2-3-1. After removing the first bolt assembly 2-3-1, the height of the covering plow handle 2-2 can be adjusted. After adjustment, the first bolt assembly 2-3-1 is inserted into the pre-drilled bolt holes of the fixed sleeve 2-3 and the locking holes 2-2-1 of the covering plow handle 2-2 and tightened.

[0039] It should be noted that, in order to ensure the tightening of the first bolt assembly 2-3-1, the support leg of the frame 1 on the rear side of the fixing sleeve 2-3 is provided with a reserved bolt hole corresponding to the reserved bolt hole of the fixing sleeve 2-3. The first bolt assembly 2-3-1 can be tightened with a nut after passing through the fixing sleeve 2-3, the locking hole 2-2-1, and the support leg of the frame 1.

[0040] In this embodiment, the plow blade 2-1 has an arc-shaped concave structure. The arc-shaped concave surfaces of both plow blades 2-1 face the inner side of the frame 1. The plow blade 2-1 body is inclined at a 45-degree angle to the forward direction of the frame 1. The rear side of the plow blade 2-1 body is drawn inward, and the front end of the plow blade 2-1 body is spread outward. It should be noted that this angle can be adjusted according to the actual working conditions.

[0041] like Figures 3 to 5 As shown, the frame 1 is equipped with roller support feet 1-1, and a cavity 1-2 is provided inside the roller support feet 1-1. A sliding groove 1-3 is provided on one side of the cavity 1-2, and the width of the sliding groove 1-3 is smaller than the width of the cavity 1-2. The pressing roller 3 includes a roller body 3-1, which is rotatably connected to a wheel axle 3-2. One end of the wheel axle 3-2 is fixedly connected to a sliding sleeve 3-3. The sliding sleeve 3-3 is movably fitted onto a column 3-4. The upper and lower ends of the column 3-4 are fixedly connected to the inner wall of the cavity 1-2. A spring 3-5 is fitted on the outer side of the column 3-4. The bottom end of the spring 3-5 is connected to the top end of the sliding sleeve 3-3, and the top end of the spring 3-5 is connected to the inner top wall of the cavity 1-2. The wheel axle 3-2 and the sliding groove 1-3 are slidably connected and engaged. The elastic force of springs 3-5 makes the frame 1 move more smoothly when the pressure roller 3 rolls, and prevents large-scale jumping.

[0042] It should be noted that in this embodiment, the distance between the two furrowing plows 4 is greater than the distance between the center points of the two roller bodies 3-1, and the distance between the two furrowing plows 4 is less than the distance between the two plow blades 2-1.

[0043] like Figures 6 to 7 As shown, the upper end surfaces of the main pressure rod 5-1 and the side pressure rod 5-2 are provided with multiple hinged ear plates 5-5, and the bottom end of the connecting rod 5-3 is fixedly provided with a short column 5-3-1, which is rotatably connected to the hinged ear plate 5-5.

[0044] A movable hole 5-4-1 is provided on the crossbeam 5-4. The connecting rod 5-3 is slidably installed in the movable hole 5-4-1. Multiple through holes 5-3-2 are provided on the body of the connecting rod 5-3. A through positioning hole 5-4-2 is provided on the side wall of the crossbeam 5-4. A second bolt assembly 5-4-3 is provided in the positioning hole 5-4-2. The through hole 5-3-2 and the positioning hole 5-4-2 are connected together by the second bolt assembly 5-4-3.

[0045] In this embodiment, both the movable hole 5-4-1 and the positioning hole 5-4-2 are elongated, while the through hole 5-3-2 is circular. The length of the movable hole 5-4-1 is longer than the diameter of the connecting rod 5-3; the length of the positioning hole 5-4-2 is longer than the diameter of the through hole 5-3-2. The reserved space design of the movable hole 5-4-1 and the positioning hole 5-4-2 allows for a certain degree of adjustment of the height of a single connecting rod 5-3.

[0046] In this embodiment, the upper end face of the main pressure rod 5-1 is provided with three connecting rods 5-3, and the upper end face of the side pressure rod 5-2 is provided with two connecting rods 5-3. By pulling out the second bolt assembly 5-4-3, the height of the connecting rods 5-3 can be adjusted, thereby adjusting the tilt angle of the side pressure rod 5-2 or the main pressure rod 5-1, so that the side pressure rod 5-2 and the main pressure rod 5-1 can better fit the soil ridge.

[0047] like Figure 1 and Figure 8 As shown, the mulch film installation mechanism 6 includes a mulch film installation rod 6-1 and a clamping mechanism 6-2. The clamping mechanism 6-2 includes a lower circular groove 6-2-1 and an upper circular groove 6-2-2, both of which are perpendicular to the forward direction of the frame 1. The lower circular groove 6-2-1 is located on the frame 1, and the upper circular groove 6-2-2 is located on the lower surface of the rotating block 6-2-3. One side of the rotating block 6-2-3 is rotatably connected to the frame 1 via a hinge. When the rotating block 6-2-3 is clamped onto the frame 1, the upper circular groove 6-2-2 and the lower circular groove 6-2-1 close to form a complete circular groove. Both ends of the mulch film installation rod 6-1 are engaged within the circular groove formed between the lower circular groove 6-2-1 and the upper circular groove 6-2-2. During operation, the mulch film is simply inserted into the mulch film installation rod 6-1.

[0048] In this embodiment, the rotating block 6-2-3 is provided with a first bolt hole 6-2-4, and the frame 1 is provided with a second bolt hole 6-2-5 at a position corresponding to the first bolt hole 6-2-4. A long bolt 6-2-6 is inserted into both the first bolt hole 6-2-4 and the second bolt hole 6-2-5. The rotating block 6-2-3 can be fixed by inserting the long bolt 6-2-6 into the first bolt hole 6-2-4 and the second bolt hole 6-2-5. When it is necessary to replace the mulch film tube, the long bolt 6-2-6 is removed, the rotating block 6-2-3 is flipped over, and the mulch film tube installation rod 6-1 can be removed to replace the new mulch film tube.

[0049] The usage process of this utility model is as follows:

[0050] First, place the device at the edge of the field, insert the plastic film tube into the plastic film tube mounting rod 6-1, and place the plastic film tube mounting rod 6-1 between the upper circular groove 6-2-2 and the lower circular groove 6-2-1. Insert the long bolt 6-2-6 into the first bolt hole 6-2-4 and the second bolt hole 6-2-5 to fix the rotating block 6-2-3. Place one end of the plastic film on the ground and press it down with soil. Pull the handle 8 forward, and the furrowing plow 4 will be inserted into the soil and gather the turned soil inward to form a soil ridge. During this process, the plastic film is continuously pulled out from the plastic film tube as the frame 1 moves forward. At the same time, the main pressure rod 5-1 and the side pressure rod 5-2 press the plastic film onto the soil ridge, ensuring that the middle of the plastic film is in contact with the soil ridge. The edge pressing roller 3 presses on both sides of the plastic film and moves forward. The plow blade 2-1 of the covering plow 2 is inserted into the soil and turns up the soil to press on both sides of the plastic film.
