Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, specifically to an agricultural mulching machine with automatic film cutting and spraying functions. Background Technology

[0002] Qinghai is a high-altitude region with low annual rainfall and relatively dry land, especially during the crop growing season when the soil's moisture retention capacity is poor. Furthermore, the soil harbors larvae and weeds. Most crops are grown using mulching to enhance soil moisture and heat retention. However, existing mulching machines only have mulching functionality, lacking spraying and automatic film cutting capabilities. Manual spraying and cutting with shovels or other tools are required, which is time-consuming and labor-intensive. To maintain and improve soil moisture and heat retention, it is necessary to spray the soil with pesticides before mulching. This improves the supply of nutrients and moisture to the soil, promoting better crop growth and increasing yield. Mulching requires spraying, mulching, and automatic film cutting devices. Therefore, developing an agricultural mulching machine with automatic film cutting that integrates multiple operations such as tilling, spraying, mulching, pressing, and covering with soil has become essential for production. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this utility model provides an agricultural mulching machine with automatic film cutting and pesticide spraying. Its structure is as follows: the frame is U-shaped horizontally. From left to right, the upper part of the frame is equipped with a traction frame, a reducer, a micro diaphragm water pump, a pesticide tank, a film support roller, and an automatic film cutting device. From left to right, the bottom of the frame is equipped with a rotary tiller, a spray nozzle, traveling wheels, a film spreading roller, a film pressing roller, and a film edge covering soil disc. The two rear ends of the frame are fitted with covering roller supports, which are rotatably connected to the two ends of the covering roller. The covering roller is hollow. The cylinder has a gap in the middle of its outer circle. The outer side of the soil covering roller support is movably connected to the soil covering disc support on the membrane through a spring shock absorption device. One end of the soil covering disc support on the membrane is provided with a soil covering disc on the membrane. The automatic membrane cutting device consists of a buckle, a crossbar, a slider, a membrane cutting knife, a spring seat, a spring, and a pull rope. The crossbar has a T-shaped groove along its length. One end of the slider is vertically T-shaped, and its T-shaped end is slidably connected to the T-shaped groove of the crossbar. The other end of the slider is fixedly connected to the membrane cutting knife. One end of the spring seat is fixedly connected to the slider, and the other end is provided with a buckle.

[0004] As a further embodiment of this utility model: the reducer has an input shaft and an output shaft respectively arranged on two mutually perpendicular surfaces, and a sprocket B is arranged at one end of the output shaft. The sprocket B is driven by a chain and a belt driven by a sprocket A arranged at one end of the rotary tiller.

[0005] As a further embodiment of this utility model: the medicine box is connected to the spray nozzle through a medicine delivery pipeline and a miniature diaphragm water pump.

[0006] As a further embodiment of this utility model, the two ends of the film support roller are provided with movable buckles.

[0007] As a further embodiment of this utility model: a film spreading roller is provided at the bottom of the frame via a film spreading roller bracket, and a film pressing roller is provided at the rear end of the film spreading roller via a film spreading roller bracket.

[0008] As a further embodiment of this utility model: the soil-covering disc on the membrane is equidistant from the soil-covering roller, and the soil-covering disc on the membrane is vertically lower than the soil-covering roller.

[0009] As a further embodiment of this utility model: the input shaft on the reducer is connected to the output shaft of the tractor, and the end of the input shaft is provided with a spline.

[0010] This utility model is used as follows: The towing frame (4) of this utility model is connected to the towing frame of the tractor. The input shaft (2) on the reducer (3) is connected to the output shaft of the tractor engine. Then, pesticides are loaded into the medicine tank (7), and mulch film (28) is installed on the film roller (8). The snap fastener (29) is locked, and the mulch film (28) is connected to the bottom of the film spreading roller (18). While the agricultural mulching machine is driven forward by the tractor towing frame, the output shaft of the tractor engine drives the input shaft (2) on the reducer (3) to rotate. The input shaft (2) drives the output shaft (25) of the reducer to rotate through the gear transmission in the reducer (3). The sprocket B (24) on the output shaft (25) drives the rotary tiller (21) to rotate through the belt transmission of the chain (23) and the sprocket A (22). After the rotary tiller (21) first tills and levels the land, the pesticides in the medicine tank (7) are controlled by the micro diaphragm water pump (5) and delivered through the pesticide delivery pipe. (6) The pesticide is sprayed evenly on the ground from the nozzle (20). Then, the film spreading roller (18) at the bottom of the frame (1) spreads the film (28) flat on the ground that has been leveled by rotary tillage. The film pressing rollers (16) on both sides at the back flatten the film (28). Then, the soil covering disc (15) at the edge of the film compacts the edge of the film. Finally, the soil covering roller support (10) connected to the rear end of the frame (1) is used to connect the soil covering roller support (10) and the soil covering roller (12). The small shaft of the head is rotated and connected. The outer side of the soil covering roller support (10) is elastically connected to the soil covering disc (13) on the membrane through the spring shock absorption device (11) and the soil covering disc support (14). Finally, the soil covering discs (13) on both sides of the rear end of the frame (1) scrape the soil into the soil covering roller (12). The soil in the soil covering roller (12) is then sprinkled onto the surface of the mulch film (28) through the curved channel set in the inner wall of the soil covering roller (12) and the gap. The mulching process is completed.

[0011] After the mulching work is completed, open the buckle (9-1). Under the force of the spring (26), the spring seat (9-5) drives the film cutting knife (9-4) to move along the T-slot slide on the crossbar (9-2) through the slider (9-3). The film cutting knife (9-4) cuts the film. After the second mulching work is completed, pull the pull rope (27) to drive the film cutting knife (9-4) to cut the film. In this way, the film cutting knife (9-4) can cut the film back and forth.

[0012] The beneficial effects of this invention are as follows: 1. This utility model relates to an agricultural mulching machine with automatic film cutting and spraying. By setting an automatic film cutting device, under the action of a spring, the spring seat drives the film cutting blade to quickly cut the film through the slider. Pulling the pull rope can also drive the film cutting blade to cut the film, so that the film cutting blade can cut the film back and forth.

[0013] 2. This utility model provides an agricultural mulching machine with automatic film cutting and pesticide spraying. By setting up a pesticide spraying mechanism, the pesticide in the pesticide tank is evenly sprayed from the spray nozzle through the delivery pipe under the control of a micro diaphragm water pump.

[0014] 3. This utility model provides an agricultural mulching machine with automatic film cutting and spraying. By setting a spring shock absorption device, the soil-covering disc on the film can dig soil and transport it to the soil-covering roller at any time according to the unevenness of the land. The soil in the soil-covering roller passes through the curved channel set in the inner wall of the soil-covering roller and then through the gap set in the outer surface of the soil-covering roller, thereby evenly spreading the soil onto the mulch film and stabilizing the mulch film on the ground.

[0015] This utility model can simultaneously complete multiple operations such as tilling, spraying, mulching, pressing, and covering with soil, effectively combining the agronomy of mulching planting with agricultural machinery, and effectively ensuring increased crop yield and income. It also features simple structure, reliable operation, low power consumption, wide adaptability, good versatility, convenient use and maintenance, and low maintenance costs, reducing manual workload and saving labor costs.
