Description
Technical Field
[0001] The utility model is applied to the field of agricultural machinery, and particularly relates to a combined operation machine for straw root stubble crushing and residual film recycling. Background Art
[0002] A straw returning machine is an agricultural machine that directly crushes and returns crop straw to the field. The straw returning machine cuts the straw in the field through a high-speed rotating blade, and evenly scatters it on the ground surface. These cut straws gradually rot and decompose in the soil, providing organic matter for the soil and improving the soil structure. In terms of straw utilization, there is also a straw recycling machine, which is a special agricultural machine for recycling crop straw. The straw recycling machine usually completes the recycling of straw through a series of actions such as picking up, conveying, and compressing. It picks up the straw in the field through a picking device, then cuts the straw into a certain length through a cutting device, and then conveys the straw to a compression device by a conveying device for compression.
[0003] At present, most of the straw returning machines and recycling machines on the market can only achieve one function separately, and the effects of separate recycling, straw crushing and wire drawing are poor. The straw returning machine uses a single throwing barrel, and after being picked up by the hammer claws, it is directly sprayed into the field through the throwing barrel, and cannot play a role in recycling. Therefore, this application provides a combined operation machine for straw root stubble crushing and residual film recycling. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a combined operation machine for straw root stubble crushing and residual film recycling, which can achieve the dual functions of straw root stubble crushing and residual film recycling.

[0007] The recycling device includes a crushing fixed knife, hammer claws, a hammer claw shaft, a main engine gearbox, a traction frame and a recycling device housing. The recycling device housing is rotatably connected to the hammer claw shaft, and the recycling device housing and the traction frame are detachably connected. The hammer claws are spirally distributed on the shaft surface of the hammer claw shaft, and the crushing fixed knife is installed on both sides inside the recycling device housing;
[0008] The main engine gearbox is transmitted to a pulley through a gear, the end of the hammer claw shaft is connected to the pulley, and the pulley drives the hammer claw shaft to rotate after two-stage speed increase.
[0009] The described straw root stubble crushing and residual film recycling combined operation machine, the hammer claws are composed of a group of long hammer claws and a group of short hammer claws, and the ends of the long hammer claws and the short hammer claws are of U-shaped frame structure, and the midline position at the U-shaped frame is on the same vertical plane as the blade of the crushing fixed knife.
[0010] The described straw root stubble crushing and residual film recycling combined operation machine, the radial interval between the crushing fixed knives is 44.5 mm, the width of the hammer claw tip is 33 mm, and the gap between the hammer claw and the crushing fixed knife reduces straw omission.
[0011] The described straw root stubble crushing and residual film recycling combined operation machine, the recycling device housing includes mounting plates on both sides and a group of wear-resistant plates between the two mounting plates, and the group of wear-resistant plates is arranged between the two mounting plates.
[0012] The described straw root stubble crushing and residual film recycling combined operation machine, the fan device includes a fan housing, fan blades and a fan shaft, the fan shaft is connected to the fan blades, both sides of the fan shaft are rotationally connected to the bearing seats of the fan housing, and the top of the fan housing is fixedly connected to the recycling device housing through bolt assemblies.
[0013] The described straw root stubble crushing and residual film recycling combined operation machine, the throwing device includes a connecting flange, a throwing barrel and a dust removal screen, the bottom of the throwing barrel is integrally connected to the connecting flange, the dust removal screen is installed at the outlet of the throwing barrel, and the connecting flange is fixedly connected to the fan housing of the fan device through a group of bolt assemblies.
[0014] The beneficial effects achieved by the present utility model are:
[0015] 1. The present utility model adopts a double-spray throwing barrel, the hammer claws are arranged in a four-row spiral and combined with fixed knives, the picking is clean, the straw crushing and silk-making effects are good, and it can be directly used as feed for feeding cattle and sheep after collection, and it can also accelerate the decay speed after returning to the field. When it is necessary to return to the field alone, the double-spray throwing barrel directly sprays to the field. When recycling is needed, a collection vehicle is arranged at the rear of the throwing barrel to achieve the purpose of collecting as feed.
[0016] 2. In the present utility model, four rows of hammer claws are arranged in a spiral structure on the hammer claw shaft. By using the cooperation between the hammer claws and the crushing fixed knives, the crushing effect and silk-making effect of the straw are greatly improved, meeting the requirements for cattle and sheep feed.

[0017] 3. In the present utility model, crushing fixed knives are installed at multiple places in the recycling device. Through the crushing fixed knives, the straw is fully kneaded and crushed during the collection process to achieve an ideal effect. At the same time, at the outlet end of the throwing barrel, a screen dust removal device is adopted to reduce dust and impurities, making the material cleaner.
[0018] 4. The active power source of this utility model is a tractor. The power transmitted by the power take-off shaft of the tractor is transmitted to the main engine gearbox through a universal joint, and then transmitted to a pulley through gear transmission. After the belt doubles the speed, it drives the hammer claw shaft to rotate at high speed. The high-speed rotation of the hammer claw shaft generates a negative pressure at the feeding port of the collector. As the main engine moves forward, the straw is affected by the negative pressure and forcibly fed by the hammer claw knives. It is blocked by the front crushing fixed knife at the entrance of the drum and is sheared and torn for the first time. Subsequently, driven by the air flow and the hammer claw knives, it moves along the inner wall of the casing drum to the fixed knife and is blocked. Due to the blockage of the crushing fixed knife, the crushing fixed knife and the hammer claws form a shear pair to shear, strike, and rub the straw multiple times, turning it into small pieces or filaments. The straw that has become small pieces or filaments is sent into the fan, and the fan sends the straw into the throwing barrel. The throwing barrel throws the straw out or collects it into the receiving transport vehicle, and can achieve the dual functions of straw root stubble crushing and residual film recycling.
