Reciprocating impact oblique tooth discharging shovel of reciprocating impact mining machine

Abstract

The invention relates to the field of mining machinery, in particular to a reciprocating impact oblique tooth discharging shovel of a reciprocating impact mining machine. The reciprocating impact oblique tooth discharging shovel of the reciprocating impact mining machine comprises a reciprocating impact box and a reciprocating impact oblique tooth discharging shovel body. The reciprocating impactbox comprises a reciprocating impact box body, a reciprocating impact power part and a reciprocating impact guiding part, the reciprocating impact guiding part is disposed in the reciprocating impactbox body, the reciprocating impact power part is supported by the reciprocating impact box body to drive the reciprocating impact guiding part, and one end or both ends of the reciprocating impact guiding part extend out of the reciprocating impact box body. The reciprocating impact oblique tooth discharging shovel body comprises a main tooth seat, a main punching tooth, a side discharging tooth wing plate and side discharging oblique teeth, and the main tooth seat is arranged on the end part of the reciprocating impact guiding part extending out of the reciprocating impact box body, the mainpunching tooth is arranged at the top end of the main tooth seat, the thickness of the side discharging tooth wing plate is smaller than that of the main tooth seat to reduce the height of the discharging surface of the reciprocating impact oblique tooth discharging shovel body, the side discharging oblique teeth are staggered or symmetrically arranged or arranged front and back on the side discharging tooth wing plate, and the tooth top ends of the side discharge oblique teeth protrude from the side plane of the side discharging tooth wing plate. Impacted sweeping materials are enabled to conveniently flow out from the gap, higher than the side discharging tooth wing plate, of the side discharging oblique teeth, and the resistance of the materials to the reciprocating impact oblique toothdischarging shovel is reduced.

Description

technical field [0001] The invention relates to the field of mining machinery, in particular to a reciprocating impact helical tooth discharge shovel of a reciprocating impact mining machine. Background technique [0002] In the process of the existing reciprocating impact mining machine impacting rock walls, coal walls, copper ore, iron ore, etc., because the diameter of the front end of the impact head is small and the diameter of the rear end is large, the impact head has no discharge structure, resulting in the materials washed down by the front end being crushed. The large impact head at the rear end is on the material wall to form a more solid material surface. Due to the large diameter of the impact head and the high resistance, the reciprocating impact head cannot reciprocate impact on the material wall, etc. Frequent reciprocating impacts of more than tens of tons often occur The reaction force caused the motor or motor that drives the reciprocating impact to be ove...

[0002] In the process of the existing reciprocating impact mining machine impacting rock walls, coal walls, copper ore, iron ore, etc., because the diameter of the front end of the impact head is small and the diameter of the rear end is large, the impact head has no discharge structure, resulting in the materials washed down by the front end being crushed. The large impact head at the rear end is on the material wall to form a more solid material surface. Due to the large diameter of the impact head and the high resistance, the reciprocating impact head cannot reciprocate impact on the material wall, etc. Frequent reciprocating impacts of more than tens of tons often occur The reaction force caused the motor or motor that drives the reciprocating impact to be overloaded and damaged, etc. Although later, a variety of impact teeth were set around the impact rod of the impact head, because the impact rod is surrounded by teeth, forming a small diameter in the front and a larger diameter in the rear. Even if it hits soft rock or soft coal, because the front of the impact head is small and the rear is large, and because the teeth of the impact head are set in the same direction front and rear, the impact teeth are set parallel to the sides of the impact teeth, and the wall of the impact material is very short. Within a short period of time, the gap between the teeth of the impact head is small in front and large in the back, which means that the material cannot flow out, causing the subsequent falling materials to be continuously crowded between the teeth of the impact head, so that the entire impact head forms a larger mushroom head impact. The impact head makes the material wall form a larger and more solid material surface because there is no discharge space. The impact head impacts again. The more impact the material surface becomes, the harder the material surface is. The increasing resistance makes it difficult to discharge and drop the material on the impact head on the material wall. The material surface does not fall, but the impact head is clenched, and the impact head is pulled off the excavator, so that the reciprocating impact excavator consumes high energy, takes a long time, has low efficiency, high failure rate, and even cannot work normally at all, let alone reach Estimated production target, in order to solve the above problems, the present invention proposes a reciprocating impact mining machine reciprocating impact helical tooth discharge shovel
