Implementation

[0016] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model, that is, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0017] Therefore, the following detailed description of the embodiments of the utility model provided in the accompanying drawings is not intended to limit the scope of the utility model claimed for protection, but merely represents selected embodiments of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0018] Combine the following Figure 1-2 The specific implementation mode of the present utility model is described.

[0019] The present embodiment provides a lifting type feeding device, which includes a feeding system and a lifting system. The feeding system includes a feed belt 1, a feed bin 2, a material blocking frame 3, and a material guide trough 4; the lifting system includes a support frame 5, a rotating pin 6, a hydraulic cylinder 7, a positioning and fixing pin 8, a telescopic positioning rod 9, a sliding seat 10, a sliding shaft 11, a sliding wheel 12, and a sliding groove 13; the two ends of the support frame 5 are respectively connected to the frame and the feed belt 1, the two ends of the hydraulic cylinder 7 are respectively connected to the frame and the support frame 5, the two ends of the telescopic positioning rod 9 are respectively connected to the frame and the support frame 5, and the sliding seat 10 is fixedly connected to the frame; the sliding wheel 12 is connected to the sliding seat 10 through the sliding shaft 11, and the sliding groove 13 is arranged at the bottom of the feed belt 1, and the sliding wheel 12 is located in the sliding groove 13 and can slide in the sliding groove 13.

[0020] The telescopic positioning rod 9 includes a telescopic tube 14 and a telescopic rod 15. The telescopic tube 14 is provided with a fixing pin hole 16. The telescopic rod 15 is provided with a plurality of positioning pin holes 17. The positioning fixing pin 8 cooperates with the fixing pin hole 16 and the positioning pin hole 17 to realize the positioning function of the telescopic positioning rod 9. The position of the feeding device can be adjusted by adjusting the telescopic amount of the hydraulic cylinder 7, and the feeding device can be further kept in a suitable position by the positioning fixing pin 8 and the telescopic positioning rod 9.

[0021] The lifting system also includes a link seat 18, which is fixedly welded to the frame, and one end of the support frame 5 is connected to the link seat 18; the link seat 18 has a support arm 19, and when the feeding device is in a retracted state, the support arm 19 has a supporting effect on the support frame 5, effectively improving the stability of the device. A buffer 20 is also provided on the upper side of the support arm 19; a buffer 21 is provided at the position of the support frame 5 corresponding to the support arm 19. When the feeding device is retracted, the buffer 20 collides with the buffer 21, effectively reducing the impact of the feeding system on the lifting system. Preferably, the buffer is made of wear-resistant plastic material.

[0022] The support frame 5, the rotating pin 6, the sliding seat 10, the sliding shaft 11, the sliding wheel 12, the sliding groove 13, and the link seat 18 are all symmetrically arranged in two groups, and the hydraulic cylinder 7 and the telescopic positioning rod 9 are symmetrically arranged, which effectively improves the stability of the lifting system.

[0023] The working principle of the utility model is:

[0024] When the mobile crushing equipment needs to be transported, the piston of the hydraulic cylinder 7 is controlled to retract. At this time, the support frame 5 will rotate downward around the rotating pin 6, driving the feeding system to move backward and downward until the piston retracts to the bottom, effectively reducing the length and height of the mobile crushing equipment to meet the transportation requirements of the equipment. When the piston retracts to the bottom, the buffer 1 20 and the buffer 2 21 will collide and contact. Since the buffer is made of wear-resistant plastic material, the impact of the feeding system on the lifting system can be effectively reduced.

[0025] When the mobile crushing equipment arrives at the construction site for operation, the piston of the hydraulic cylinder 7 is controlled to extend. At this time, the support frame 5 will rotate upward around the rotating pin 6, driving the feeding system to move forward and upward until it reaches the required position at the construction site, and then the telescopic positioning rod 9 is locked by the positioning fixing pin 8 to keep the feeding device at the required position.

[0026] Since the sliding wheel 12 and the sliding groove 13 are provided, the sliding groove 13 will move with the feeding system during the movement of the feeding system, and the sliding wheel 12 slides in the sliding groove 13, effectively reducing the resistance of the feeding system to movement.

[0027] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", etc. should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
