Detailed Description

The present application is described in further detail below with reference to figures 1-2.

The embodiment of the application discloses auxiliary device of double-roll crusher.

Referring to fig. 1, the auxiliary device of the double roller crusher includes a feed pipe 100 and a driving part 200, the feed pipe 100 being vertically disposed and having both ends respectively communicating with the double roller crusher and a feed hopper. The driving part 200 includes a hydraulic cylinder 210 and a screw rod 230, the hydraulic cylinder 210 is horizontally fixed on both side walls of the double-roll crusher, and the screw rod 230 is horizontally rotated on both side walls of the double-roll crusher. One end of a screw rod 230 penetrates through the double-roller crusher, the other end of the screw rod 230 is arranged outside the double-roller crusher, a gear 240 is coaxially fixed at one end of the screw rod 230 arranged outside the double-roller crusher, a rack 220 is horizontally fixed on a hydraulic cylinder 210, the rack 220 is connected with the side wall of the double-roller crusher in a sliding mode, the rack 220 is meshed with the gear 240, and the hydraulic cylinder 210 is powered by a hydraulic pump. The hydraulic cylinder 210 is activated, the hydraulic cylinder 210 expands or contracts, so as to drive the rack 220 to move, and the rack 220 drives the gear 240 to rotate, so as to drive the lead screw 230 to rotate.

Referring to fig. 2, a push rod 310 is coaxially and threadedly connected to one end of the screw 230, which is disposed inside the twin-roll crusher, and a push plate 300 is fixed to one end of the push rod 310, which is away from the screw 230. When the material drops into the feeder hopper, start hydraulic cylinder 210, hydraulic cylinder 210 stretches to drive lead screw 230's rotation, thereby make two push pedal 300 move in opposite directions, thereby extrude the material, make big material and harder material broken in advance, then break in getting into the clearance between drive roll and the driven voller again.

In order to further improve the extrusion crushing effect of the push plates 300 on the materials, crushing teeth 320 are fixed on the opposite surfaces of the two push plates 300.

In order to protect the push rod 310 and the lead screw 230 and guide the sliding of the push plate 300, an arc-shaped baffle plate 330 is fixed on the push plate 300, the baffle plate 330 is horizontally connected with the side wall of the double-roller crusher in a sliding manner, one end of the baffle plate 330 penetrates through the side wall of the double-roller crusher, and the baffle plate 330 is arranged above the push rod 310.

In order to make the material in the feeding pipe 100 enter the gap between the driving roller and the driven roller as much as possible, guide plates 400 are obliquely arranged on both inner side walls of the double feeding pipe 100, the guide plates 400 are arranged below the push rod 310, and one end of the guide plates 400 close to the push rod 310 is higher than one end of the guide plates 400 far away from the push rod 310. The two guide plates 400 are slidably connected to the side walls of the feeding pipe 100, so that the gap between the two guide plates 400 is adapted to the gap between the driving roller and the driven roller.

In order to limit the sliding of the guide plate 400, the outer walls of the two sides of the feeding pipe 100 are welded with the abutting nuts 410, the abutting nuts 410 are connected with the abutting bolts 420 in an internal thread mode, and the length direction of the abutting bolts 420 is perpendicular to the length direction of the guide plate 400 and can be abutted to the guide plate 400. After the driving guide plate 400 slides, the tightening bolt 420 is rotated, so that the tightening bolt 420 abuts against the guide plate 400, and the sliding of the guide plate 400 is limited.

The implementation principle of the auxiliary device of the double-roll crusher is as follows: when the material drops into the feeder hopper, start hydraulic cylinder 210, hydraulic cylinder 210 stretches, thereby drive the removal of rack 220, rack 220 drives the rotation of gear 240, gear 240 drives the rotation of lead screw 230, thereby make two push pedal 300 remove in opposite directions, thereby extrude the material, make big material and harder material broken in advance, then break in getting into the clearance between drive roll and the driven voller, consequently, the condition of jam between drive roll and the driven voller clearance has been reduced.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
