Description

Technical Field

[0001] The utility model relates to the field of agricultural machinery, in particular to a farmland mulch film cleaning device. Background Art

[0002] Ground mulch is widely used in agricultural planting. Covering the soil with ground mulch can retain moisture, maintain temperature, protect soil structure and prevent diseases. Due to its low cost, most ground mulch is not recycled at present. Most ground mulch is left in the fields for natural degradation and is directly buried in the soil during spring ploughing. Long-term accumulation will cause pollution to the fields. Ground mulch decomposes into plastic particles, affecting the root growth and development of crops, and has a great impact on crop growth and economic value.

[0003] In order to reduce the pollution of ground film to the environment and the impact of ground film residue on crops, it is necessary to recycle and separate the ground film. Existing ground film recycling machinery usually adopts a winding method. When recycling, it is necessary to first remove the covering soil and use the winding roller to reel in the ground film. However, after one year of use, the ground film is exposed to direct sunlight and rain erosion and aging, and it is very easy to be torn, and the broken ground film remains in the field; and after the breakage occurs, it needs to be frequently manually connected, which is inconvenient to operate and has high labor intensity.

[0017] As Figure 1 , Figure 2 shown: A farmland plastic film cleaning device includes a machine shell 1, a rotary tillage mechanism 2, a plastic film separation mechanism 3 and a burning and cleaning mechanism 4. A suspension connector 5 is fixedly provided on the machine shell 1. The suspension connector 5 is used to connect with the hitch of a tractor and can be mounted at the rear of an agricultural machine during use, which is a common structure in the field of agricultural machinery. Gearboxes 101 are provided on both sides of the machine shell 1. The rotary tillage mechanism 2 is horizontally arranged inside the machine shell 1 through both sides of the machine shell 1. The rotary tillage mechanism 2 includes a rotary tillage shaft 201 and rotary tillage discs 202. A number of rotary tillage discs 202 are arranged along the length direction of the rotary tillage shaft 201. Rotary tillage blades 203 are sequentially arranged circumferentially on both sides of the rotary tillage discs 202. When the rotary tillage mechanism 2 works, the rotary tillage shaft 201 drives the rotary tillage discs 202 to rotate. The rotary tillage blades 203 on the rotary tillage discs 202 shovel into the soil, turn over and break a certain thickness of soil, and at the same time bring out the plastic film covered in the soil. Parallel to the rotary tillage mechanism 2 and above the rotary tillage mechanism 2, there is a plastic film separation mechanism 3. The plastic film separation mechanism 3 is placed at the rear side of the rotary tillage mechanism 2. The plastic film separation mechanism 3 includes a plastic film separation shaft 301 and a number of plastic film dial plates 302 fixedly installed on the plastic film separation shaft 301. A number of dial rods 303 are fixedly arranged along the circumference in the radial direction of the plastic film dial plates 302. A plastic film dial plate 302 is arranged between every two rotary tillage discs 202. The plastic film dial plates 302 rotate in the same direction as the rotary tillage discs 202. After the rotary tillage blades 203 turn up the plastic film, it will wind around the rotary tillage blades 203, and then the plastic film dial plates 302 peel off and lift up the plastic film wound around the rotary tillage blades 203. The dial rods 303 on the plastic film dial plates 302 can hook the plastic film. Through the above structure, the plastic film can be turned out from the covered soil and the separation of the soil and the plastic film can be completed.

[0018] As Figure 3As shown in the figure: A burning cleaning mechanism 4 is fixedly arranged at the top of the machine housing 1 and behind the rotary tillage mechanism 2. The burning cleaning mechanism 4 includes a burner 401, a fuel storage tank 402, and an electronic ignition device 403. A fuel storage tank 402 is fixedly installed at the top of the machine housing 1. Liquefied petroleum gas or methane can be used as fuel. Using liquefied gas fuel has the advantages of low usage cost, easy acquisition, and safety. The fuel storage tank 402 is connected to the burner 401 through a pipeline. The structure of the burner 401 is the same as that of the existing flame spray gun using liquefied gas fuel, which is a well-known prior art to those skilled in the art, so it will not be elaborated here. The burner 401 of the burning cleaning mechanism 4 faces the bottom of the film separation mechanism 3. After the film dial 302 picks up and separates the film from the rotary tillage blade 203 and rotates it to the flame range of the burner 401, the flame quickly melts and burns the film. Most of the carbides generated adhere to the film dial 302 and will not pollute the soil. The carbides on the ground can be cleaned after use. An electronic ignition device 403 is installed at the end of the burner 401. During use, open the valve at the outlet of the fuel storage tank 402, and the combustible gas is introduced into the burner 401. The burner 401 is ignited by the electric arc generated by the electronic ignition device 403. Then start the rotary tillage mechanism 2 and the film separation mechanism 3 to start the mechanized cleaning of the film in the field.

[0019] The power of the present utility model comes from the transmission shaft on the agricultural machine and is connected to the worm transmission mechanism 103 through a universal joint. A drive shaft 102 is provided through the gear boxes 101 on both sides of the machine housing 1. A worm transmission mechanism 103 connected to the drive shaft 102 is provided on the machine housing 1. The rotary tillage shaft 201 of the rotary tillage mechanism 2 is connected to the drive shaft 102 through gear transmission. The film separation shaft 301 of the film separation mechanism 3 is connected to the drive shaft 102 through belt transmission. The speed ratio of the rotary tillage shaft 201 to the film separation shaft 301 is 1:5, so that the speed of the film dial 302 is lower than that of the rotary tillage disc 202. During operation, the film dial 302 can keep the separated film in the flame of the burner 401 for as long as possible, making the film burn more fully.
