Description

Technical Field

[0001] This utility model relates to the field of farmland treatment technology, specifically a combined operation device for straw return to the field and soil leveling. Background Technology

[0002] Arable land is developed from natural soil, but not all soil can be developed into arable land. After crops are harvested in arable land, the straw needs to be returned to the field, and the land also needs to be leveled.

[0003] A search revealed that the announcement number is CN218353196U, and the name is "A Combined Microbial Fertilizer Operation Device for Returning Corn Stalks to the Field". It includes a feeding box. Research and analysis revealed that although it has the advantages of finely crushing the straw and mixing the straw with microbial fertilizer more thoroughly, it also has the following disadvantages to a certain extent.

[0004] For example, during the use of this device, it can only return straw to the field, but cannot level the land, which is inconvenient for subsequent heavier operations and for people to use. In order to solve the above technical problems, we have designed a combined straw returning and soil leveling operation device. Utility Model Content

[0005] The purpose of this utility model is to provide a combined straw return and soil leveling operation device, which has the advantages of both straw return and soil leveling. It solves the problem that the device can only return straw to the field but cannot level the land, making it inconvenient for subsequent heavier operations and user-friendly.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a combined straw return and soil leveling operation device, comprising a mounting shell, a rotary tiller rotatably connected to the inner cavity of the mounting shell, a first pulley bolted to the right side of the rotary tiller, a drive motor bolted to the right side of the top of the mounting shell, a drive shaft bolted to the drive motor and a second pulley bolted to the drive shaft, a connecting frame welded to the top of the mounting shell, a crushing shell welded to the front of the connecting frame, a crushing roller rotatably connected to the inner cavity of the crushing shell, and a bolted connection to the right side of the crushing roller. There is a third belt pulley. A gear is bolted to the left side of the crushing roller. A first drive belt is connected between the second and third belt pulleys. A finding plate is rotatably connected to the rear side of the mounting shell. A fixing block is welded to the top of the mounting shell. A first hydraulic rod is bolted to the rear side of the fixing block. A movable block is rotatably connected to the bottom of the first hydraulic rod. A connector is rotatably connected to the top of the finding plate. A positioning bolt is bolted to the top of the connector. A spring is welded to the bottom of the movable block. The bottom of the spring is welded to the connector.

[0007] Preferably, a protective shell is bolted to the left side of the crushing shell, and two gears mesh between them.

[0008] Preferably, the bottom of the positioning bolt passes through the movable block, and the surface of the positioning bolt is slidably connected to the movable block.

[0009] Preferably, the bottom of the first hydraulic rod is bolted to a connecting block, and the front side of the movable block is rotatably connected to the connecting block.

[0010] Preferably, a bearing is provided at the connection between the surface of the rotary tiller and the mounting shell, and a second drive belt is connected between the second pulley and the first pulley.

[0011] Preferably, a second hydraulic rod is bolted to the top of the mounting housing, and an assembly frame is fixedly fitted onto the surface of the second hydraulic rod.

[0012] Preferably, the top of the mounting housing is bolted to a limiting rod, the top of which passes through the assembly frame and is slidably connected to the assembly frame.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model uses an assembly frame to install the device onto agricultural machinery, which then carries the device. The second hydraulic rod extends and retracts, causing the mounting shell and rotary tiller to move up and down. Simultaneously, the drive shaft of the drive machine drives the second pulley to rotate, which in turn drives the second drive belt to rotate. The second drive belt then drives the first pulley and rotary tiller to rotate, and the rotary tiller then renovates the farmland. This invention places the straw to be returned to the field inside a crushing shell. The transmission shaft of the second belt pulley drives the first drive belt to rotate, which in turn drives the third belt pulley to rotate. The third belt pulley drives the crushing roller to rotate, which in turn drives the gear to rotate. The crushing roller crushes the straw, which then falls to the ground through the crushing shell. The crushed straw is then mixed into the tilled land by the rotation of the rotary tiller. The extension and retraction of the first hydraulic rod drives the movable block to move up and down, which in turn drives the spring to move up and down, which in turn drives the connecting head to move up and down. The connecting head drives the leveling plate to rotate, which levels the tilled soil and prevents large potholes from forming. Attached Figure Description
