Embodiment 1

[0036] Such as figure 1 , figure 2 As shown, the present embodiment provides a cutting blade with an impact function, including a blade housing 1 and a blade head 5, a telescopic mechanism is arranged on the blade housing 1, and one end of the telescopic mechanism is connected to the blade head 5 , drive the shovel head 5 to reciprocate through the telescopic mechanism.

[0037] Wherein, the telescoping mechanism includes a power source and a crank link mechanism, the power source is connected in transmission with the crank link mechanism, and one end of the crank link mechanism is connected to the shovel head 5 . In this embodiment, the power source is a hydraulic motor with high torque and low speed. The hydraulic motor is small in size and easy to install.

[0038] The crank-link mechanism includes a crank 301 , a connecting rod 302 and a sliding rod 303 connected in sequence, the hydraulic motor is in transmission connection with the crank 301 , and the connecting rod i...

Embodiment 2

[0043] This embodiment provides a roadheader shovel with an impact function, the structure of which is as described in Embodiment 1, the difference lies in that the power source is a motor. There are 10 rows of cylindrical rollers symmetrically arranged on both sides of the bottom of the shovel head 5, and 15 rows of ball groups are arranged in parallel between the cylindrical rollers on both sides. The adjacent ball groups are arranged at equal intervals, and each row of ball groups contains 5 Ball 6.

Embodiment 3

[0045] Such as Figure 8 and Figure 9 As shown, a roadheader shovel with impact function, the structure is as described in Embodiment 1, the difference is that cylindrical rollers 8 are symmetrically arranged on the left and right sides of the slide rail seat 4, and cylindrical rollers are arranged symmetrically on the upper and lower sides. Roller. The cylindrical rollers on the upper and lower sides are alternately distributed with the cylindrical rollers on the left and right sides. Installing cylindrical rollers 8 up, down, left, and right inside the slide rail seat 4 can make the slide bar move more smoothly, and the rolling friction is easier than the sliding friction.

[0046] One side of the cylindrical roller is provided with a cylindrical roller baffle 7, which can effectively prevent the radial movement of the cylindrical roller 8 and only ensure the axial rotation of the cylindrical roller 8. Bolts are installed at both ends of the cylindrical roller 8 to preve...

Abstract

The invention relates to a tunneling machine shovel plate with an impact function and application of the tunneling machine shovel plate. The shovel plate comprises a shovel plate shell and a shovel plate head, wherein the shovel plate shell is provided with a telescopic mechanism; one end of the telescopic mechanism is connected with the shovel plate head; the telescopic mechanism drives the shovel plate head to move in a reciprocating manner; the telescopic mechanism comprises a power source and a crank-connecting rod mechanism; the power source is connected with the crank-connecting rod mechanism in a transmission manner; one end of the crank-connecting rod mechanism is connected with the shovel plate head. The tunneling machine shovel plate with the impact function disclosed by the invention has the advantages that the impact function is added under the condition of not affecting the function of the shovel plate; the shovel plate can perform impact disturbance on materials in the shovel plate propelling process, so that a material stack is loosened, the propelling force of the shovel plate is reduced, the abrasion of the front end of the shovel plate is reduced, the service life of the shovel plate is prolonged, the working efficiency is improved at the same time, the effects of obvious effect, significant effect, excellent economic benefits and excellent market value are achieved, and the shovel plate is worthy of popularization and application.

Description

technical field [0001] The invention relates to a shovel plate of a roadheader with an impact function and an application thereof, belonging to the technical field of roadheaders. Background technique [0002] The roadheader is equipment used in coal mines for the development of underground rock roadways, semi-coal rocks and coal roadway working faces, and has high mining efficiency. The roadheader is mainly composed of walking, cutting, shoveling, and conveying mechanisms. The shovel mechanism is one of the main working mechanisms of the roadheader. It mainly collects the materials cut by the cutting mechanism, shovels the materials cut off by the cutting mechanism onto the shovel plate, and passes through the star wheel on the shovel plate. The material is picked up in the middle of the shovel, and the material is transported out by the first conveyor in the middle of the shovel, and its performance directly affects the production capacity of the roadheader. At present, t...
