Detailed Description
The invention will be further explained with reference to the drawings.
The utility model provides a belt doffer, its characterized in that, is including setting up in the rotatory material collecting device 2 of band conveyer blanking district, rotatory material collecting device 2 below has the buffering chute 12 that the slant set up, is provided with material collecting device under the buffering chute 12.
The blanking area of the conveying device is the lower part of a belt head pulley 1 of the conveying belt, the blanking area of the conveying device is set to be a cavity, a dustproof cavity wall 14 is arranged outside the cavity, the belt head pulley 1, the rotary material receiving device 2, the adjustable chute 4, the emergency discharger 5, the shield 8, the regulator 9, the buffer chute 12 and the material receiving baffle 13 are arranged in the cavity, and the bottom of the cavity is connected with the guide chute. The dust-proof cavity wall 14 can prevent dust generated by blanking from flying, and a dust removal device can be arranged in the cavity or connected with the dust removal device on the dust-proof cavity wall to perform dust removal treatment on the dust flying.
The material receiving device comprises a material guide groove 10 and a material receiving belt 11 below the material guide groove.
The included angle α between the buffer chute and the horizontal direction is 20-40 degrees, and the buffer chute 12 is a straight chute or a curved chute.
The rotary material receiving device 2 comprises a rotating wheel 21 and a plurality of material distribution plates 22 arranged on the rotating wheel 21; the position of the rotary material receiving device 2 is adjustable in the vertical direction and the horizontal direction, and the rotary material receiving device 2 is installed below the conveying belt head pulley 1 through the adjustable installation device 18 and can be adjusted in position through the adjustable installation device.
The rotary material receiving device 2 is also connected with a backstop 3.
The side lower part of the rotary material receiving device 2 is also provided with an adjustable chute 4, one end of the adjustable chute 4 is connected with a supporting rotating shaft 14, the other end of the adjustable chute 4 is connected with an adjuster 9, and the bottom of the adjustable chute 4 faces a buffer chute 12.
The adjustable chute 4 upper end still is provided with emergent tripper 5, emergent tripper 5 includes rotation axis 15 and balance plate 16, and 16 one ends of balance plate are provided with weight 6, and the other end is connected with and connects material baffle 13, connect material baffle 13 conflict adjustable chute 4 upper end rear portion, the balance plate below is provided with proximity switch 7, and proximity switch 7 electricity is connected regulator 9.
The regulator 9 is a hydraulic cylinder, and a protective cover 8 is arranged on the regulator 9.
The bottom end of the adjustable chute 4 is further provided with a buffer plate 17, the included angle β between the buffer plate and the adjustable chute is 165-170 degrees, and the length of the buffer plate is 300-800mm, preferably 500 mm.
As shown in figure 1, materials fall from a belt head pulley 1 to a rotary receiving device 2, and the rotary receiving device starts to discharge the materials to an adjustable chute 4 through a buffer chute 12 to a receiving belt 11 through a guide chute 10 automatically due to the impact of the materials. The rotary receiving device 2 is provided with a backstop 3 to prevent the material from going directly to the buffer chute 12 without passing through the adjustable chute 4. In the feeding process, due to different particle sizes of raw materials, the big blocks lean against the front part, the small blocks lean against the back part, the small blocks falling in advance and the powder material play a certain protection role on the rotary distributing device, and meanwhile, the wear-resistant layer is arranged on the partition plate of the rotary receiving device 2, so that the service life of the rotary distributing device is prolonged.
The rear portion of the adjustable chute 4 is provided with an emergency discharger 5, when material blockage occurs, the emergency discharger 5 is automatically opened under the action of gravity and touches the proximity switch 7, so that the regulator 9 starts to work, at the moment, the angle of the adjustable chute 4 is increased, quick discharging is realized, after the material blockage phenomenon is eliminated, the emergency discharger 5 recovers the original position under the action of the heavy hammer 6 and is separated from the proximity switch 7, and the regulator 9 also recovers the original position to normally discharge.

The material receiving baffle 13 is kept in a horizontal closed state during normal feeding. When material jamming occurs between the rotary distributor and the adjustable chute during feeding, as shown in fig. 4, the material is accumulated on the material receiving baffle 13, and when the accumulated material reaches a certain weight, the material receiving baffle 13 drives the balance plate 16 to automatically open and discharge under the action of gravity.
According to the head drop height of the material dropping point, when the drop height is larger than the diameter of the head wheel and is not more than 1.2 times of the diameter, a set of rotary material receiving devices (the vertical and horizontal average during installation) is added, so that the material drop is reduced to be below the conventional 1/3, the final speed of the material dropping point is also greatly reduced, namely the flow of the material in the chute is increased, but the speed is reduced. When the fall height reaches more than 1.5 times of the diameter of the head wheel, the rotary material receiving device is added, and the adjustable buffer chute is added. To prevent material accumulation, the angle of the buffer chute can be adjusted, so that the material flow is adjusted. When the feed chute drop is bigger, can set up the bend chute according to the space size in addition to taking above measure, the purpose reduces material flow speed, eliminates with higher speed, reaches the dust fall and prevents only the damaged purpose of material.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the gist of the present invention.
