Description

Technical Field

[0001] The utility model relates to a drip irrigation pipe for farmland irrigation, in particular to a drip irrigation pipe cutting device for a film-laying seeder. Background Art

[0002] Drip irrigation is one of the most effective technical measures for water-saving irrigation. Under the same conditions, the advantages of drip irrigation infiltration are: first, it wets part of the soil surface, effectively reduces the ineffective evaporation of soil moisture, and prevents the growth of weeds. The drip irrigation system does not produce surface runoff, and it is easy to accurately control the depth of water application. Second, after drip irrigation, the soil root system has good permeability. By injecting fertilizers into the water, sufficient water and nutrients can be provided to keep the soil moisture in a stable and low suction state that can meet the requirements of crops. The small ground evaporation in the irrigation area can effectively control the humidity in the protected area, greatly reduce the incidence of diseases and insect pests of crops in the field, and also reduce the amount of pesticides used. Third, it improves the quality of crop products. Because drip irrigation can supply water and fertilizer in a timely and appropriate amount, it can improve and improve the quality of agricultural products while increasing crop yields, greatly increasing the commodity rate of agricultural products in protected areas. Fourth, it saves water and labor, and increases production and income. Because during irrigation, water does not move in the air, does not wet the leaves, and does not evaporate from the soil surface outside the effective wetted area, the amount of water directly lost to evaporation is minimal; it is easy to control the amount of water, and does not cause surface runoff and deep soil leakage. Therefore, it can save 35%-75% of water compared to sprinkler irrigation. It has opened up a new way to realize water conservancy in arid areas with few water sources and water shortages. Therefore, in recent years, combined operation seeders that can complete soil loosening, root cutting, sowing, fertilization, drip pipe laying, and suppression at one time have quickly appeared and developed and promoted.

[0003] However, in actual sowing operations, when the drip irrigation pipe planter reaches the end of the field, the drip irrigation pipe must be cut before it can enter the next operation path irregularly. At present, the drip irrigation belt is cut by an automated cutting tool. Generally, these tools are equipped with an automated processor for program control. The drip irrigation pipe is clamped first and then cut. Although this is convenient, after the automated cutting tool is damaged, the maintenance cost is very high. It is often necessary to replace a new cutting tool, which not only increases the production operation cost, but also makes it difficult to quickly replace it in remote rural areas, delaying the farming time. Sometimes it has to be cut manually, which requires two people to complete and takes a long time. Therefore, it is urgent to develop a small, simple, and non-destructive drip irrigation pipe cutting device. Utility Model Content

[0004] The technical problem to be solved by the utility model is to develop a small, simple and non-damageable drip irrigation pipe cutting device in response to the above urgent needs, and provide a drip irrigation pipe cutting device for a film laying planter. The cutting device has the characteristics of simple structure, easy operation, firmness and durability, and easy processing, and can be matched with various types of drip irrigation pipe laying planters.

[0005] The technical problem to be solved by the utility model is achieved by the following structure: a drip irrigation pipe cutting device for a film-laying seeding machine, the structure comprising a vertical bracket, a horizontal bracket, a base, a clamping mechanism, a cutting mechanism, a cushion block, and an electric telescopic rod base.

[0006] The clamping mechanism comprises an electric telescopic rod, a fixing bolt and nut, a dynamic clamping block, a fixed clamping block and a slideway, and its function is to clamp the drip irrigation pipe when it is needed to be cut so that the blade can cut the drip irrigation pipe.

[0007] The electric telescopic rod base is fixed on the base by countersunk bolts.

[0008] The electric telescopic rod base is fixed with the electric telescopic rod by fixing bolts. The function of the electric telescopic rod is to push and pull the clamping block forward or backward. One end of the dynamic clamping block is connected to the electric telescopic rod by bolts and nuts. A slide groove is processed at the bottom, and the block can move left and right on the slide. The slide is welded on the pad.

[0009] The cushion block is fixed on the base through countersunk bolts.

[0010] A fixed clamping block is welded on the base, and its function is to clamp the drip irrigation pipe together with the dynamic clamping block.

[0011] The cutting mechanism includes a blade and a micro motor, and its function is to cut off the drip irrigation pipe. The micro motor is mounted on the fixed clamping block through a fixing bolt, and the blade is mounted on the shaft end of the micro motor. The blade is sawtooth-shaped, with 12 to 15 teeth, a tooth top angle of 60° to 70°, and a tooth height of 3 to 4 mm.

[0012] The bottom plates are welded on both sides of the base to receive the drip irrigation pipe guide. The drip irrigation pipe guides are welded on the bottom plates on both sides of the base, and the center of the drip irrigation pipe guides is directly opposite to the vicinity where the movable clamping block contacts the fixed clamping block. The function of the guides is to support and guide the drip irrigation pipe, so that the blade can cut the drip irrigation pipe.

[0013] The mounting holes on the dynamic clamping block and the electric telescopic rod are elongated, so that the blade and the dynamic clamping block can be adjusted according to the cutting condition of the blade to improve the cutting quality.

[0014] A switch contact is installed on one side of the movable clamping block, and a micro switch is installed on the side of the fixed clamping block in the same direction. Its function is that when the movable clamping block contacts the fixed clamping block and clamps the drip irrigation pipe, the switch contact touches the micro switch, and the micro motor of the circuit connected thereto is turned on and rotates, driving the blade to cut the drip irrigation pipe.

[0015] The working principle of the drip irrigation pipe cutting device for the film laying seeder is as follows: when the drip irrigation pipe laying seeder reaches the end of the field, the driver operates the main switch button to connect the circuit, driving the electric telescopic rod to push the moving clamping block forward to slide, and when the moving clamping block touches the fixed clamping block, the drip irrigation pipe is clamped, and at the same time, the contact installed on the moving clamping block touches the micro switch installed on the side of the fixed clamping block, connecting the micro motor circuit, and the micro motor rotates to drive the blade to cut the drip irrigation pipe. After cutting, manually press the main switch to close the circuit, and then the electric telescopic rod returns to its position, and at the same time pulls the moving clamping block back to its initial position.

[0016] The advantages of the drip irrigation pipe cutting device for the film-laying seeder are: 1. It can automatically cut the drip irrigation pipe, and only needs to manually operate the main switch button, the cutting section is neat, and the cutting efficiency is high; 2. The structure is simple and can be manufactured by a general small-scale machinery processing factory; 3. It can be used in conjunction with various types of seeders.
