TECHNICAL FIELD

[0001] The utility model relates to the technical field of grinding, specifically to a toothed roll crushing tooth plate and side comb plate adjusting structure. BACKGROUND

[0002] Toothed roll crusher: it is the crushing equipment used in the ore crushing industry, and the current equipment crushing mode is center crushing and two side crushing; the center crushing mainly relies on the relative motion of the crushing teeth installed on the roller cover to cross and bite the ore for crushing operation; and the two side crushing mainly relies on the cooperation of the crushing tooth plate and the side comb plate for ore crushing operation. Among them, the crushing tooth plate is the main part of the toothed roll crusher, which forms a relative motion shearing space for ore through the power transmission of the roller cover.

[0003] The prior art CN105498900A is a through type double-toothed roll crusher with side tooth plate mounting and adjusting device and adjusting method; the adjusting form of the side comb plate of the toothed roll crusher and the rack is adopted, the movable side tooth plate is freely horizontally moved on the lower side plate of the box body through the distance adjusting lead screw mechanism, the change of the material particle size is adjusted and adapted, and the product particle size after crushing is controlled. That is, by adjusting the distance adjusting lead screw mechanism, the movable side tooth plate is slid to the crushing roller, the crushing particle size control space is reduced or increased, and the product particle size after crushing is reduced or retained;

[0004] Problems: the adjustment of the lead screw is limited by the several turns of the screw thread above the lead screw to confirm the stability of the side comb plate, when the material hardness is too high, repeated impact on the side comb plate can cause the screw thread of the lead screw to loosen, the side comb plate to move backward, the product particle size to be too large, and the maintenance personnel to need to maintain multiple times. The structure is limited by the quality of the lead screw and the fatigue resistance of the metal, and the lead screw cannot be replaced, so the service life of the traditional adjusting equipment is limited.

[0005] Therefore, we provide a toothed roll crushing tooth plate and side comb plate adjusting structure to solve the above problems. UTILITY MODEL CONTENTS

[0007] The utility model discloses a toothed roll crushing tooth plate and side comb plate adjusting structure to make up for the deficiency of prior art, and solve the technical problem that repeated impact on the side comb plate can cause the screw thread of the lead screw to loosen, so that the side comb plate cannot stably crush ore.

[0008] Rack;

[0009] Crushing tooth plate, a plurality of tooth shapes are formed on the crushing tooth plate;

[0010] The side comb plate is provided with a plurality of rows of comb teeth on the side of the side comb plate facing the crushing tooth plate, and a set of tooth shapes is arranged between adjacent comb teeth;

[0011] The mounting plate is provided with a fixing bolt between the mounting plate and the rack, a positioning bolt between the mounting plate and the side comb plate, and a pad plate on the positioning bolt on the side of the mounting plate away from the crushing tooth plate. A locking nut is arranged on the positioning bolt. A thickening pad is arranged between the locking nut and the pad plate.

[0012] In a further technical solution, a wear-resistant plate is fixedly installed on the side of the rack facing the crushing tooth plate, and the wear-resistant plate covers at least 80% of the side of the rack facing the crushing tooth plate.

[0013] In a further technical solution, the mounting plate includes a main body portion and two side portions, the main body portion is stepped on the side facing the crushing tooth plate, and the height of the end portion is less than the height of the corresponding side comb plate.

[0014] A fixing screw hole is formed in the two side portions, and a fixing bolt is arranged in the fixing screw hole.

[0015] The shank of the fixing bolt passes through the rack and is threadedly connected with the two side portions.

[0016] In a further technical solution, the positioning bolt is a conical flat head bolt, and the end portion of the positioning bolt is flush with the side of the side comb plate facing the crushing tooth plate.

[0017] In a further technical solution, the main body portion and the two side portions are flush on the side away from the crushing tooth plate.

[0018] A stop opening is arranged in the rack, and the stop opening is suitable for clamping when the two side portions are installed.
