Description

Technical Field

[0001] This utility model relates to the field of rotary tiller technology, specifically a rotary tiller with residual film collection function. Background Technology

[0002] Rotary tillers are tillage machines that work in conjunction with tractors to perform tilling and harrowing operations. They are widely used because of their strong soil-breaking ability and the flat surface they leave after tilling; at the same time, they can chop up the stubble buried below the surface, making it easier for seeders to operate and providing a good seedbed for later sowing.

[0003] During cultivation, a large amount of residual agricultural film is difficult to decompose naturally in the soil, affecting the water, fertilizer, air, and heat activities in the soil, causing serious pollution to the soil environment, and is not conducive to the ecological balance of agriculture. However, existing rotary tillers cannot collect the residual film in the soil during cultivation, which in turn affects crop growth.

[0004] Therefore, we propose a rotary tiller with residual film collection function. Utility Model Content

[0005] The purpose of this invention is to provide a rotary tiller with residual film collection function to solve the problems mentioned in the background art.

[0007] Optionally, the rotary tiller body includes a bracket connected to a tractor and rotating rotary blades. The suction troughs are fixedly installed on the bracket of the rotary tiller body, and the two suction troughs are symmetrically arranged on both sides above the rotating blades of the rotary tiller body.

[0008] Optionally, the bottom of the suction trough is provided with a feed inlet, the length of which is the same as the arrangement length of the rotating blades of the rotary tiller body.

[0009] Optionally, a roller is rotatably connected to the inner circumferential surface of the rotating groove, the roller makes rolling contact with the outer circumferential surface of the filter cone, a connecting frame is fixedly installed at the top inside the filter cone, and the fan blade is fixedly installed at the top of the connecting frame.

[0010] Optionally, the bottom of the fixing frame is fixedly installed with a fixing pin hole, and the bottom of the filter cone is provided with a rotating pin rod, which is detachably and rotatably connected to the fixing pin hole at the bottom of the fixing frame.

[0011] Optionally, the mounting bracket has a symmetrical V-shaped structure, and a cleaning brush is provided on the side of the mounting bracket facing the filter cone.

[0012] Optionally, the top of the collection box is provided with a sealing ring, the bottom of the box cover is provided with a sealing groove corresponding to the sealing groove, and the box cover and both sides of the collection box are provided with snap-on buckles.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This rotary tiller with residual film collection function, by setting up a collection box, can turn over the residual film in the soil during the tilling process by the rotary tiller blades. The residual film is sucked into the collection box through the suction trough and air duct by the suction action of the blower. The filter cone set on the cover of the collection box filters the air, so that the residual film is collected when the rotary tiller is working.

[0015] 2. This rotary tiller with residual film collection function has a filter cone with a mesh structure. Under the action of airflow, the fan blades drive the filter cone to rotate, scraping off the residual film on the filter cone through the fixed frame. Even if the inner wall of the storage box is blocked, the airflow can still be discharged through the filter cone, which can prevent the residual film from clogging the storage box and reducing the collection efficiency.

By setting up the collection box 5, when the rotary tiller body 1 is working, the rotary tiller blades can turn over the residual plastic film in the soil during the tilling process. Using the suction effect of the blower 7, the residual film is sucked into the collection box 5 through the suction trough 2 and the air duct 4. The filter cone 10 set in the box cover 6 of the collection box 5 filters the air, so that the rotary tiller body 1 collects the residual plastic film when it is working.

[0024] The rotary tiller body 1 includes a bracket connected to a tractor and rotating rotary blades. A material suction trough 2 is fixedly installed on the bracket of the rotary tiller body 1. Two material suction troughs 2 are symmetrically arranged on both sides above the rotating blades of the rotary tiller body 1. A feed inlet 3 is provided at the bottom of the material suction trough 2, the length of which is the same as the length of the rotating blades of the rotary tiller body 1.

Even if the inner wall of the storage box is blocked, the airflow can still be discharged through the filter cone 10, which can prevent the residual film from blocking the storage box and reducing the collection efficiency.

[0025] Working principle:

[0026] When the rotary tiller body 1 is working, the rotary tiller blades can agitate the residual mulch film in the soil during the tilling process. Using the suction effect of the blower 7, the residual film is sucked into the collection box 5 through the suction trough 2 and the air duct 4. The filter cone 10 set in the cover 6 of the collection box 5 filters the air, so that the rotary tiller body 1 can collect the residual mulch film when working. The filter cone 10 has a mesh structure. Under the action of airflow, the fan blade 12 will drive the filter cone 10 to rotate, and scrape the residual film on the filter cone 10 through the fixing frame 14. Even if the inner wall of the storage box is blocked, the airflow can still be discharged through the filter cone 10, which can prevent the residual film from blocking the storage box and reducing the collection efficiency.
