Detailed Description

The present invention is further described with reference to the following drawings and examples, which are not intended to limit the scope of the present invention.

As shown in fig. 1-3, the utility model discloses a crawler shovel loader comprises a frame 1. The frame 1 is used for providing support for other parts, and other parts are all arranged on the frame 1.

A walking crawler system 2 is arranged below the frame 1, and a belt conveyor 3 is arranged above the frame. And the front end of the belt conveyor 3 is provided with a shoveling and digging system 4.

The walking crawler system 2 is used for driving the crawler shovel loader to move. The utility model discloses in, as shown in fig. 4, walking crawler system 2 can include driven athey wheel 2.1, initiative athey wheel 2.2 and cover and establish track 2.3 on driven athey wheel 2.1 and the initiative athey wheel 2.2. The driving crawler wheels 2.2 are arranged on a crawler driving shaft. And the driving mechanism is also arranged on the track driving shaft. The driving mechanism drives the track driving shaft to rotate. The driving crawler belt wheel 2.2 is driven by the crawler belt driving shaft to rotate. The driving crawler wheels 2.2 rotate to drive the crawler belts 2.3 to rotate, and then walking is achieved.

The scooping system 4 is used to perform scooping and crushing to dig a pit on the ground or the like and to convey scooped dregs or the like upward, that is, to send the dregs or the like onto the belt conveyor 3.

In the present invention, the shoveling system 4 includes a shovel 4.1. A shoveling shaft 4.2 is arranged in the shoveling bucket 4.1. And the shoveling shaft 4.2 is provided with a shoveling grid block 4.3. A first hydraulic motor may be mounted on the shoveling shaft 4.2. The shoveling shaft 4.2 is driven to rotate by the first hydraulic motor. The shoveling shaft 4.2 rotates to drive the shoveling grid blocks 4.3 to rotate, so that shoveling operation is realized. The shovel bucket 4.1 is used for ensuring that shoveled dregs and the like are conveyed to the belt conveyor 3, and can play a role in protecting safety and protecting the shoveling grid 4.3 and the like.

In the present invention, the two sides of the shoveling and digging system 4 are respectively connected to the two sides of the belt conveyor 3 through a hydraulic lifting arm 5. Wherein one end of the hydraulic lifting arm 5 may be connected to the belt conveyor 3 through a rotating shaft, so that the hydraulic lifting arm 5 can rotate around the rotating shaft relative to the belt conveyor 3. The other end of the hydraulic lifting arm 5 is connected with the shoveling system 4. A first hydraulic oil cylinder 6 for driving the hydraulic lifting arm 5 is arranged between the belt conveyor 3 and each hydraulic lifting arm 5.

Thus, when the cylinder rod of the first hydraulic cylinder 6 extends, it pushes one end of the hydraulic lifting arm 5 to rotate counterclockwise around the rotating shaft, so that the other end of the hydraulic lifting arm 5 moves to a high place, i.e., the shoveling system 4 is driven to move to a high place. When the cylinder rod of the first hydraulic cylinder 6 retracts, it pushes one end of the hydraulic lifting arm 5 to rotate clockwise around the rotating shaft, so that the other end of the hydraulic lifting arm 5 moves to the lower position, that is, the shoveling system 4 is driven to move to the lower position. Therefore, on one hand, the height of the shoveling system 4 can be adjusted, so that shoveling operation can be conveniently carried out in different places; on the other hand, the scooping system 4 may be raised after scooping so that scooped earth and slag or the like can be discharged onto the front end of the belt conveyor 3.

The belt conveyor 3 is used for conveying the dregs and the like generated by the shoveling and digging operation of the shoveling and digging system 4 outwards. As shown in fig. 1, in the present invention, the belt conveyor 3 includes a frame body 3.1. The frame body 3.1 is used for providing support for other parts of the belt conveyor 3.

The rear end of the frame body 3.1 is provided with a driving belt pulley 3.2, and the front end is provided with a driven belt pulley 3.3. And a conveying belt 3.4 is sleeved on the driving belt pulley 3.2 and the driven belt pulley 3.3. A second hydraulic motor may be mounted on the drive shaft on which the drive pulley 3.2 is mounted. The driving shaft is driven to rotate by the second hydraulic motor, so that the driving belt pulley 3.2 is driven to rotate. The rotation of the driving belt pulley 3.2 drives the conveying belt 3.4 to rotate, so that the dregs and the like are conveyed from the front end to the rear end of the belt conveyor 3.

Preferably, the frame body 3.1 is further provided with a plurality of supporting wheel sets 3.5 for supporting the conveying belt 3.4. With the supporting wheel set 3.5, it is possible to increase the transport capacity of the belt conveyor 3.

More preferably, a walking auxiliary wheel 3.5 is further arranged below the front end of the frame body 3.1. In this way, when the walking crawler system 2 walks, the walking assistance wheels 3.5 are in contact with the ground, on the one hand helping to support the belt conveyor 3 and on the other hand helping to assist it in walking along the ground.

Preferably, the frame body 3.1 is connected with the upper end of the frame 1 through a second hydraulic cylinder 7 and a rotating shaft 8. One end of the second hydraulic oil cylinder 2 is connected with the upper end of the rack 1, and the other end of the second hydraulic oil cylinder is connected with the rack body 3.1. Thus, when the cylinder rod of the second hydraulic cylinder 2 is extended, it causes the belt conveyor 3 to rotate clockwise about the rotating shaft 8, so that the rear end of the belt conveyor 3 can be tilted. When the cylinder rod of the second hydraulic cylinder 2 is contracted, it causes the belt conveyor 3 to rotate counterclockwise about the rotary shaft 8, so that the belt conveyor 3 can be made to be in a flat state or the rear end of the belt conveyor 3 is lowered. In this way, it is convenient to adjust the state of the belt conveyor 3, thereby facilitating the conveyance of the dregs or the like generated by the shoveling operation of the shoveling system 4.

As shown in fig. 4, in the present invention, a diesel engine 10 and a hydraulic station 11 are further disposed on the frame 1. The output shaft of the diesel engine 10 is connected with the input shaft of the hydraulic station 11 so as to drive the hydraulic station 11 through the diesel engine 10, so that the hydraulic station 11 generates oil pressure to drive the belt conveyor 3, the shoveling and digging system 4, the first hydraulic oil cylinder 6, the second hydraulic oil cylinder 7 and the like.

The hydraulic station 11 may have a plurality of oil passages. For example, the first oil path of the hydraulic station 11 may be connected to a first hydraulic motor for driving the cutting shaft 4.2, so that the cutting shaft 4.2 is driven to rotate by the first hydraulic motor, thereby realizing cutting operation. The second oil path of the hydraulic station 11 may be connected to a second hydraulic motor that drives a driving pulley of the belt conveyor 3, so that the belt conveyor 3 is driven to rotate by the second hydraulic motor, thereby conveying the residue and the like generated by the shoveling and digging operation. The third oil path of the hydraulic station 11 may be connected to the first hydraulic cylinder 6, so as to control the lifting of the shoveling and excavating system 4 through the first hydraulic cylinder 6. The fourth oil circuit of the hydraulic station 11 may be connected to the second hydraulic cylinder 7 to enable control of the state of the belt conveyor 3 by means of the second hydraulic cylinder 7. Thus, the utility model discloses a track shovel digs each part of loader carries out the oil feed and control by same hydraulic pressure station, can be more stable.

Finally, in the present invention, it is preferable that a steering wheel 9 is further installed on the frame 1. The traveling direction of the traveling crawler system 2 can be changed by the steering wheel 9, so that it is more convenient to move.

The above embodiments of the present invention are merely examples for clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. Not all embodiments are exhaustive. All obvious changes or variations led out by the technical scheme of the utility model are still in the protection scope of the utility model.
