The garbage is discharged into the rear garbage bin 31 , the dust is discharged into the bottom garbage bin 16 , and the rubber particles are discharged along the rubber particle discharge board 17 .

The working process of the present invention is:

Garbage cleaning process:

When the playground sweeper is cleaning, first the whole machine is powered on, and the disk brush motors 24 on both sides of the front of the car are powered on and start to rotate inward, and at the same time drive the coupling 25, the disk brush bracket 23, and the disk brush 22 to rotate inwardly, The disc brush 22 rubs against the turf, and the garbage on the turf is affected by the force along the rotation direction of the disc brush 22, and moves to the middle direction of the two disc brushes 22, that is, the garbage on the turf gathers from both sides to the middle and spreads on the disc brush 22. Sod surface on the inside.

With the push of manpower, the sweeper moves forward. At the same time, the roller brush motor 35 rotates at a high speed, and drives the roller brush 29 to rotate clockwise in the forward direction through the roller brush coupling 34. Between the roller brush 29 and the roller brush cover 30 With a gap of several millimeters left, the roller brush 29 sweeps the collected garbage by giving the garbage a tangential force in the oblique upward direction, and bounces several times along the inner wall of the roller brush cover 30 to move the garbage and open along the roller brush cover 30. The direction is thrown to the rear, that is, on the belt conveyor located behind the cleaning device.

Garbage Delivery Process:

The front rubber particles and garbage are thrown onto the conveyor belt 4 with stop bars. The conveyor belt 4 is inclined to the plane of the vehicle body. The conveyor belt 4 is driven by the conveyor motor 5 to rotate continuously, and the material is transported to the rear end of the sweeper for screening. In the device, the transfer of garbage is completed at this time.

The separation process of garbage and rubber particles:

The left vibration motor 14-1 and the right vibration motor 14-2 jointly generate vibration force, which is transmitted to the box 11 through the vibration motor support 13, and the box 11 drives the upper sieve plate 15-1 and the lower sieve plate 15-2 vibrate together. The conveying belt 4 conveys the cleaned garbage, rubber particles, and dust mixture to the upper screen plate 15-1 of the screening device assembly.

Under the action of vibration force, the mixture moves to the lower right along the inclination of the upper sieve plate 15-1. There are sieve holes with a diameter of 5 mm on the upper sieve plate 15-1. When the mixture passes through the upper sieve plate 15-1, the volume is large. The rubbish cannot pass through the sieve holes, and is finally collected in the rear rubbish bin 31, and the rubber particles and dust fall on the lower sieve plate 15-2 through the sieve holes on the upper sieve plate 15-1.

Under the action of the vibration force, the mixture of rubber particles and dust gradually moves to the right and downward along the inclination of the lower sieve plate 15-2. The lower sieve plate 15-2 has sieve holes with a diameter of 2 mm, and the mixture passes through the lower sieve plate 15 At -2, the larger rubber particles cannot pass through the sieve holes, and are finally discharged back to the rubber playground through the rubber particle discharge plate 17. The dust falls into the bottom rubbish bin 16 through the sieve holes on the lower sieve plate 15-2.

The upper sieve plate 15-1 can make a circular motion along the upper curved groove 11-3 of the box body with the end point of the vertical groove 11-1 on the box body as the center, thereby changing the inclination angle of the upper sieve plate 15-1, so it can be adjusted according to different situations degree of filtering.

The lower sieve plate 15-2 can make a circular motion along the lower curved groove 11-4 of the box by taking the midpoint of the lower vertical groove 11-2 of the box as the center of the circle, thereby changing the inclination angle of the lower sieve plate 15-2, so it can be adjusted according to different situations. Adjust the degree of filtering.

The rubber particle row plate 17 can move left and right along the long transverse groove 11-5 of the box body.

Through the above process, the cleaning, transmission, separation and collection of the mixture of garbage, rubber particles and dust are realized, and the various garbage and dust on the playground can be efficiently removed without harming the rubber lawn and removing the rubber particles. , the purpose of low-cost removal.
