Based on the examples in the embodiments, those skilled in the art can obtain other examples without making any inventive effort, which fall within the scope of the utility model. The experimental methods in the following examples are conventional methods unless otherwise specified, and materials, reagents, etc. used in the following examples are commercially available unless otherwise specified.

Embodiment one:

As shown in fig. 1-4, a continuous pusher for materials comprises a pushing part 1, a pushing posture adjusting part 2, a pushing rod 3, a walking part 4 and a power pump station 5.

The pushing part 1 is a core part of the equipment, and continuous pushing, withdrawing and other actions in the material pushing operation are completed by the part. The pushing part 1 comprises a bottom frame 6, a pushing chain 7, a push rod 8, a lengthening arm 9, a guide shaft 10, a screw rod 11, a chain frame 12, a chain 13, a chain wheel 14, a driving motor 15 and a guide wheel 16. The bottom frame 6 is a frame structure formed by welding rectangular tubes, pin shafts, steel plates and the like, and is fixedly connected with a rotary support of the propulsion posture adjusting part 2 through the pin shafts welded at the rear side of the bottom frame. Two circular guide shafts 10 are arranged in parallel at the bottom of the bottom frame 6, and two symmetrically arranged chain frames 12 are sleeved on and slide along the two circular guide shafts through bearing blocks and self-lubricating bearings. The sliding power synchronously moves in opposite directions with the action of a screw nut of a chain frame 12 through a screw rod 11 (left-right rotation) fixed on a bottom frame triangle, so that the distance between the left chain 13 and the right chain 13 is adjusted, the rubber block arranged on the chain 13 can clamp the push rod 8, and the push rod 8 is pushed to continuously move by the generated friction force when the chain 13 is driven.

The structure has the advantages that the chain spacing adjustment range is 0-100 mm, and the structure can be suitable for pushing rod operations with various specifications below 100 mm. And because the structure is that a plurality of chain rubber blocks are contacted with the push rod, the friction propulsion force is large, the slipping phenomenon is not easy to occur, and the stability of the propulsion operation is ensured.

The power of the chain 13 is supplied by a sprocket 14 engaged therewith via a drive motor 15. The extension arm 9 is mounted on the upper part of the bottom frame 6 through bolts, and the guide wheel 16 on the extension arm guides the push rod 8 to push along the set pushing direction so as to prevent the push rod from bending. The propulsion speed is controlled by the hydraulic flow control valve, so that the speed and the inching switching can be realized, and the device is simple and convenient.

The main body of the propulsion posture adjusting part 2 is a square tube welded upright post 17, the square tube welded upright post is arranged on a walking chassis through a rotary motor 18, a square sleeve of a lifting cross beam 19 is sleeved on the upright post 17 and is driven by a lifting oil cylinder 20 to slide up and down along the upright post 17, a telescopic beam 21 is arranged in the beam and can horizontally stretch out and draw back, and the end part of the telescopic beam is connected with a propeller supporting seat 22 through the rotary motor to drive a propeller so as to adjust the propulsion posture.

Because the positioning and aligning action devices such as rotary lifting and telescoping are configured, the requirements of six degrees of freedom of the propeller on posture adjustment can be met, and the adaptability of the equipment is greatly improved. The pushing gesture adjusting part 2 is also provided with an operation column 3 which is convenient for personnel to operate.

The travelling mechanism can adopt various structural forms in the prior art, for example, a crawler travelling mechanism can be adopted to adapt to the complex geological environment of the underground coal mine, and the adaptability, the maneuverability and the flexibility of the equipment are all the prior art.

The power pump station is a hydraulic system powered by a pneumatic motor, and is used for providing power and controlling for the running mechanism, each oil cylinder, motor and other executing mechanisms, which are all in the prior art.

The working principle of the invention is as follows:

The equipment is arranged at the corresponding position of the drilling hole in the operation tunnel, is fixed after the pushing gesture is adjusted, and starts the propeller motor to drive the push rod to feed into the drilling hole. The specific working steps are as follows:

(1) And (3) machine moving positioning:

The walking part 4 is operated to move the equipment to the position of the feeding drilling hole required in the roadway, the oil cylinder, the rotary motor and the like with the operation gesture adjusted are operated to enable the height, the angle and other positions of the propeller to be consistent with the position of the drilling hole required to be propelled, and the next step can be performed to propel the operation. The propeller provided by the invention can meet the requirements of posture adjustment of six degrees of freedom of the propeller due to the arrangement of the positioning and aligning action devices such as rotary lifting and telescoping, has a wide adjustment range and simple adjustment operation, and greatly improves the adaptability of equipment.

(2) Propelling: putting the material to be pushed into the orifice

After the adjustment and positioning of the pushing gesture are completed, the materials to be pushed into the orifice are placed into the orifice, or the pushing device is turned on to push the materials into the orifice, then continuous pushing is started, the motor of the pushing device drives the sprocket chain, the pushing rod is driven to continuously move under the friction force of the rubber blocks of the chains at two sides, and the materials are pushed into the drill hole to a designated position to stop. And after the motor is reversely started, the push rod is withdrawn, and materials are continuously put into the push rod to repeat the actions until the construction requirement is met. And (5) after the hole pushing operation is completed, repositioning the machine, and starting the next operation flow.
