Self-propelled cattle shed precision mixing and spreading vehicle

Abstract

A self-propelled cattle shed precision mixing and spreading vehicle, when working, pushes the auger hydraulic distributor to drive the special-toothed auger shaft mechanism to rotate to mix the material. After the mixing work is completed, the driver pushes the forward gear lever and controls the steering wheel to drive into the spreading work area, and pushes the gear lever of the hydraulically controlled lifting mechanism to the left or right according to the actual needs of the cattle shed, and the left or right spreading door is opened to spread the material. The weighing data of the weighing sensor is transmitted to the display in the cab. The user can control the amount of feed according to the individual size of the cattle in the farm. The side of the spreading door is engraved with numbers 1 to 7, and the spreading door can be opened to the required digital position to spread the material, which can avoid the insufficient feeding amount affecting the cattle's feed intake or the excessive feeding amount causing waste. After the spreading operation is completed, the spreading door and the rotation of the special-toothed auger shaft mechanism are closed to complete a spreading work.

After the working area, according to the actual needs of the cattle shed, the lever of the hydraulic distributor (4) of the lifting mechanism is pushed to the left or right to drive the hydraulic control lifting mechanism (8) to open the left or right feeding door (13) to spread the feed.

The feeding door (13) can be opened to the required digital position to spread the feed, which can avoid the influence of insufficient feeding. The excessive feed intake or feeding amount of the cattle causes waste. After the spreading operation is completed, the spreading door (13) and the rotation of the special-shaped toothed auger shaft mechanism (16) are closed to complete one spreading operation. The diesel tank (17) provides fuel for the low-speed engine (20), the gear oil tank (5) provides gear oil for the auger shaft reducer (26), and the hand-cranked grease pump (9) adds grease to the special-shaped toothed auger shaft mechanism (16).
