Problems solved by technology

The current toothed roller crusher is relatively compact in design, so the reserved space at the bottom is small. When the mud picking teeth are worn out, maintenance personnel need to climb to the bottom of the crusher to adjust the position of the mud picking teeth one by one, which is very inconvenient
In the scene where the mud picking teeth are more worn, the daily production and maintenance are more cumbersome

Embodiment Construction

[0011] In order to further understand the invention content, characteristics and effects of the present invention, the following examples are given, and detailed descriptions are as follows in conjunction with the accompanying drawings:

[0012] see figure 1 and figure 2 In the figure, the roller skin 7 and the shell 8 are parts associated with the mud-removing tooth structure on the toothed roller crusher. First, the beam shaft 4 is installed on the cage 5 with a row of mud-removing teeth 6 fixed. After the two ends of the beam shaft 4 are installed with the cage 5, they are installed with the shell 8 of the crusher and fixed on the shell by nuts 9. On the body 8, the cage 5 can rotate around the beam shaft 4; the bottom of the cage 5 is connected with the eye nut 2 through the pin shaft 3, and the eye nut 2 is connected with the adjusting screw 1 by threads. Screw in the adjusting screw 1, through the transmission of the ring nut 2 and the pin shaft 3, push the cage 5 to ...

Abstract

The invention relates to an adjustable mud-scraping gear structure for a rod-toothed crusher, which comprises a holder and a mud-scraping gear. The adjustable mud-scraping gear structure for the rod-toothed crusher is characterized in that: a beam shaft is arranged on the holder; the two ends of the beam shaft are assembled with the holder and then assembled with a shell of the crusher and fixed by a nut; and the bottom of the holder is connected with an eyenut, which is connected with an adjusting screw rod, by a pin shaft. The adjustable mud-scraping gear structure for the rod-toothed crusher has the advantages of rational structure design, easy processing and manufacturing, simple production and maintenance and convenient adjustment.

Description

technical field [0001] The invention belongs to the field of viscous material crushing, in particular to an adjustable mud-removing tooth structure for a toothed roller crusher. Background technique [0002] The toothed roller crusher is generally used for crushing viscous materials. It mainly uses two toothed rollers rotating at the same speed or at different speeds to squeeze or shear the materials, and then discharge them from between the two rollers. The mud-removing device is located under the roller, and several mud-removing teeth are respectively fixed on the cage with bolts. The working surface of the mud picking teeth is coated with wear-resistant materials, and is inserted tangentially between the teeth of the roller. When the roller rotates, it can scrape off the clay to avoid the mud roller. When the working part of the mud picking tooth is worn out, and the distance between the mud picking tooth and the roller exceeds the specified value (> 20mm), it must be...
