Technical Field

The utility model belongs to the field of planting and breeding equipment, and particularly relates to a sawdust sowing device.

Background

In the planting and breeding industry, sawdust needs to be sowed on the ground to keep dry or provide rest places for livestock and poultry, and the prior art generally adopts manual sowing, so that the labor intensity is high, the efficiency is low, the effect of uneven sowing is not good, and the material waste is large.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a sawdust spreading device which is simple in structure and good in spreading effect.

The technical scheme for achieving the purpose comprises the following contents.

The utility model provides a device is scattered to sawdust, including the automobile body of taking the walking wheel, be equipped with the charging hopper on the automobile body, the charging hopper bottom is equipped with the export, still include the filter screen, roller group and shale shaker, the filter screen links to each other with the vibrator and sets up the middle part at the charging hopper, roller group is including the roller that 4 or more than 4 levels that parallel set up, the roller is high range after low in the past backward and preceding, roller group sets up the below at the charging hopper export, the shale shaker sets up the front lower place at roller group, in operation, each roller of roller group is rotated forward by the walking wheel drive. The sawdust falls on the roller set after being filtered by the filter screen in the charging hopper, is transmitted to the front end of the roller set by the roller rotating forwards and falls on the vibrating screen, and passes through the vibrating screen holes and falls on the ground.

Further, the walking wheel is connected with the foremost roller of the roller group through a first chain wheel transmission mechanism, the first chain wheel transmission mechanism is in one-way transmission, chain wheel transmission mechanisms are arranged between the adjacent rollers of the roller group, and during operation, the foremost roller of the roller group transmits power to the last roller one by one.

Furthermore, a plurality of grooves parallel to the axial direction are arranged on the cylinder surface of the roller in parallel along the circumferential direction. The grooves are arranged to facilitate better forward conveying of sawdust.

Furthermore, the flute depth is 0.8-1.2mm, and the width is 2-5 mm. Proper flute size is favorable for smooth conveying of sawdust.

Further, the diameter of the roller is 70-80 mm. The proper diameter of the roller is beneficial to reducing the volume of the device so as to achieve the effect of smoothly conveying the sawdust.

Further, the gap between adjacent rollers is 1.0-2.5 mm. The proper roller gap is beneficial to avoiding the sawdust from falling in the roller gap and ensuring the smooth forward conveying of the sawdust.

Further, the number of the rollers is 6.

Further, the aperture of the vibrating screen is 6-10 mm.

When the sawdust spreading device is used, firstly, sawdust is put into a charging hopper, a vibrator and a vibrating screen are started, a tractor body is pulled to move forwards, a filter screen vibrates to carry out coarse screening on the sawdust, and large-particle sawdust and impurities (wood blocks, fibrous sawdust, stone residues and the like) are left on the filter screen; the roller is driven by the travelling wheels to rotate forwards, sawdust falls on the surface of the roller and is conveyed forwards gradually, the sawdust falls on the vibrating screen from the front side surface of the roller at the foremost end, and is vibrated and scattered and uniformly scattered on the ground under the action of the vibrating screen.

The sawdust discharging amount of the sawdust spreading device is in direct proportion to the moving speed of the vehicle body, the roller does not rotate as long as the vehicle body does not move, sawdust does not discharge, the speed of the vehicle body is high, the rotating speed of the roller is high, and the sawdust discharges quickly, so that the effects of uniformly discharging and spreading sawdust are good, the operating efficiency is high, and the travelling wheels can be driven by manpower or electromechanical power.

The front and the back of the scheme take the advancing direction of the vehicle body as reference.
