Technical Field

[0001] The utility model relates to the field of buffer feeding of shot blasting machines, in particular to a buffer feeding structure of a crawler type shot blasting machine. Background Art

[0002] Crawler shot blasting machine is a kind of shot blasting machine, which is mainly suitable for processing some smaller workpieces. When using crawler shot blasting machine, the workpiece needs to be introduced at the feed port. At present, the workpiece is usually dumped directly onto the crawler of the shot blasting machine manually or through a guide hopper. The direct impact of the workpiece on the crawler will damage the crawler, which is easy to shorten the service life of the crawler, and the workpieces will also cause wear and collision, resulting in damage to the workpiece. The Chinese utility model patent with application number 202311528658.5 discloses a flexible loading and unloading device for crawler shot blasting machine, which is designed with a reversible conveyor belt mechanism, and the rotation point of the conveyor belt mechanism is concentric with the front roller body of the crawler mechanism of the shot blasting machine. During the rotation process, the distance between the conveyor belt mechanism and the front roller body is constant, and the side support frame can be used to lift and support the conveyor belt mechanism. The transmission of the conveyor belt mechanism cooperates with the crawler mechanism of the shot blasting machine to carry out flexible loading and unloading, avoiding impact and damage to the crawler of the shot blasting machine, and ensuring the position stability and service life of the crawler.

[0003] The above-mentioned flexible loading and unloading device can play a role in flexible loading for the crawler shot blasting machine. However, it is transmitted through a conveyor belt, and the workpieces will still push and collide with each other when entering the shot blasting machine, which cannot reduce the damage between the workpieces; and it has many components and a complex structure, which is not conducive to reducing production costs and equipment failure rates. Summary of the invention

[0004] In view of the shortcomings of the prior art, the utility model provides a buffer feeding structure for a crawler type shot blasting machine, which can solve the problems of workpieces pushing and colliding with each other during feeding, and the large number of components and complex structure, which are not conducive to reducing production costs and equipment failure rates.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a crawler-type shot blasting machine buffer feeding structure, including a workbench, and legs are respectively provided at the four corners of the bottom surface of the workbench. Universal wheels with a limiting function are provided at the bottom of the legs, and the front end of the workbench extends to form a feeding platform, and a rectangular unloading port is embedded in the central position of the feeding platform.

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example 1

[0028] like Figures 1 to 4 As shown, a buffering feeding structure of a crawler-type shot blasting machine comprises a workbench 1, and legs 11 are respectively provided at the four corners of the bottom surface of the workbench 1. A universal wheel 111 with a limiting function is provided at the bottom of the legs 11, and the front end of the workbench 1 extends to form a feeding platform 2, and a rectangular unloading opening is embedded in the central position of the feeding platform 2. The left and right sides of the upper surfaces of the workbench 1 and the feeding platform 2 are respectively embedded with a front-to-back direction and a through slide 3 (a rectangular groove with an upper opening), and a feeding box 4 that can slide forward and backward and can unload materials at the bottom is provided in the slide 3.

[0029] The loading box 4 includes a box body 41, which is a rectangular structure with openings at the top and bottom. The left and right baffles of the box body 41 are symmetrically provided with slideway grooves 42 (rectangular grooves) with rear openings. A support plate 43 that can be pulled forward is embedded in the slideway groove 42. The baffle on the front side of the box body 41 is provided with a rectangular opening 44 that slides with the support plate 43. The center position of the front side of the support plate 43 is also fixed with an N-shaped handle 45 lying forward. Slide blocks 46 (rectangular parallelepiped) that cooperate with the slideway 3 are fixedly provided at the front and rear ends of the bottom surface of the left and right side plates of the box body 41.

[0030] The upper surface of the support plate 43 is provided with a ceramic layer (for wear resistance).

[0031] Rectangular slots 12 are provided on the upper surface of the workbench 1 at intervals in front and back and pass through from left to right.

[0032] Rubber blocks 22 are fixedly provided on the bottom surfaces of the left and right sides of the front end of the loading platform 2, which are rectangular in shape and in contact with the crawler belt to protect the crawler belt.

[0033] The front and rear ends of the slideway 3 do not extend to the edge, so that the box body 41 cannot slide out.

[0034] A rectangular tray 5 is also fixedly disposed on the inner side of the supporting legs 11 on the upper side of the universal wheel 111 .

[0035] When in use, the universal wheel 111 facilitates the entire device to move to the feed port of the shot blasting machine, so that the loading platform 2 enters the upper side of the crawler track inside the shot blasting machine (the height of the bottom surface of the loading platform 2 is greater than the height of the bottom surface of the feed port), and then the universal wheel 111 is limited, and the loading box 4 can slide forward from the workbench 1 to the loading platform 2 on the front side. At this time, the loading platform 2 is pressed and tilted downward, and the rubber block 22 on the lower side of the front end of the loading platform 2 contacts the crawler track, and then the bottom opening of the loading box 4 is opened (pull out the support plate 43), and the workpiece can be unloaded from the bottom through the unloading port 21, and the workpiece can fall directly onto the crawler track, which effectively plays a buffering role, avoids impacting the crawler track and pushing the workpiece, and protects both the crawler track and the workpiece. After the workpiece falls, the loading platform 2 returns to a horizontal state, and then the limit state of the universal wheel 111 is released, and the device can be pulled out. Specifically, the pallet 43 in the box 41 can be spread out horizontally to store workpieces. The box 41 is pushed to the front side, and the front end of the device tilts downward due to uneven force. Then the pallet 43 is pulled out through the N-shaped handle 45, and the workpiece falls on the track under the action of gravity. After the device is withdrawn, the pallet 43 is pushed into the box 41 and the box 41 is pulled back to its original position, waiting for the next use. The rectangular pallet 5 can store things and increase the function of the device. The rectangular slot 12 is a reserved insertion space for the front fork of the forklift, which is convenient for lifting the box 41 and the workpiece onto the workbench 1. Example 2

[0036] like Figure 5 As shown, the bottom surfaces of the left and right sides of the front end of the support plate 43 are respectively embedded with screw holes 431 upward, and the limiting bolts 47 are screwed into the screw holes 431 from bottom to top.

[0037] When in use, the limiting bolts 47 limit the support plate 43 to prevent it from being pulled backwards out of the box body 41 , while facilitating the support plate 43 to be pushed into the box body 41 .
