Description

Technical Field

[0001] The utility model relates to a chassis structure of a shot blasting machine, belonging to the technical field of shot blasting machines. Background Art

[0002] A shot blasting machine is a commonly used surface treatment device. Shot blasting materials (such as steel shots, sand grains, etc.) are projected onto the surface of a workpiece at a certain speed and angle by a high-speed rotating shot blasting wheel. The impact and grinding effects of these materials on the workpiece surface are used to achieve purposes such as cleaning, strengthening, and deburring. When the existing drum through-type shot blasting machine is in use, the effect of the shot material collection device for the shot material feeding is not good. Because the shot material collection device is arranged below the support plate of the drum, holes communicating with the feeding device are opened in the middle section of the support plate, so that the shot enters the shot material collection device through the holes. However, during operation, a lot of shots fly outside the communication holes of the collection device and stay below the drum, which is difficult to clean and causes waste of shots at the same time.

[0003] Therefore, how to provide a chassis structure of a shot blasting machine that is convenient for recycling shots is the research purpose of the utility model. Content of the Utility Model

[0004] Aiming at the above technical deficiencies, the utility model provides a chassis structure of a shot blasting machine. The shots are guided by the diversion plates distributed inside the chassis to the recovery tank at the bottom of the chassis, and the spiral feeder in the recovery tank conveys the shots to the elevator. The elevator conveys the shots to the separator for screening, which is convenient for recycling and utilization.

[0005] In order to solve the problems of the existing technology, the technical solution adopted by the utility model is:

[0006] A chassis structure of a shot blasting machine, characterized in that: it includes a chassis body and a box cover provided at the top of the chassis body. A through-feed roller is provided along the length direction at the top end inside the chassis body, and a recovery tank is integrally provided at the bottom end. A spiral feeder is provided along the length direction inside the recovery tank. One end of the recovery tank is connected and communicated with a discharge pipe. Diversion plates are distributed inside the chassis body and above the recovery tank, and a sieve plate is provided between the diversion plates and the recovery tank.

[0007] Further, the lower half of the chassis body is set as a funnel-shaped structure with a wider top and a narrower bottom, and the recovery tank is integrally connected and communicated at the bottom of the funnel-shaped structure of the chassis body.

[0008] Further, eight groups of spray guns are distributed along the circumferential and length directions on the outer sides of the chassis body and the box cover.

[0009] Further, dust suction ports are provided at both ends of the box cover, and the dust suction ports are communicated and provided above the feed roller.

[0010] The beneficial effects of the present utility model are as follows: 1. The deflectors distributed inside the chassis guide the projectiles to the recovery tank at the bottom of the chassis, and the spiral feeder in the recovery tank conveys the projectiles to the elevator. The elevator transports the projectiles to the separator for screening, facilitating recycling; 2. The dust suction port is connected to a negative pressure fan to suck away the dust generated by shot blasting, avoiding dust pollution of the workshop environment. Description of the Drawings

[0018] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the following further analyzes the present utility model in conjunction with the attached Figures 1-6 drawings.

[0019] As Figures 1-5 shown, a chassis structure of a shot blasting machine, characterized in that: it includes a chassis body 1 and a box cover 2 provided on the top of the chassis body 1. A through feeding roller 3 is provided along the length direction at the top end inside the chassis body 1, and a recovery tank 4 is integrally provided at the bottom end. A spiral feeder 5 is provided along the length direction inside the recovery tank 4. One end of the recovery tank 4 is connected and communicated with a discharge pipe 6, and the discharge pipe 6 is connected to the feed pipe of the elevator to transfer the projectiles in the recovery tank 4 into the elevator. Deflectors 7 are distributed inside the chassis body 1 and above the recovery tank 4. A sieve plate 8 is provided between the deflector 7 and the recovery tank 4 to prevent sundries larger than the projectiles from falling into the recovery tank 4 and affecting the normal recovery of the projectiles.

[0020] In this embodiment, preferably, the lower half of the chassis body 1 is arranged in a funnel-shaped structure with a wider upper part and a narrower lower part, and the recovery tank 4 is integrally and communicatively connected to the bottom of the funnel-shaped structure of the chassis body 1.

[0021] In this embodiment, preferably, as Figure 6 shown, eight groups of spray guns 9 are distributed along the circumferential and length directions on the outer sides of the chassis body 1 and the lid 2, and the surfaces of the aluminum profiles on the feeding roller 3 are subjected to shot peening by the eight groups of spray guns 9.

[0022] In this embodiment, preferably, dust suction ports 10 are provided at both ends of the lid 2, and the dust suction ports 10 are communicatively arranged above the feeding roller 3 and are used to connect a negative pressure fan to suck away the dust generated by shot peening to avoid polluting the workshop environment.

[0023] The specific working principle of the present utility model: After the shot ejected by the spray gun 9 performs shot peening on the surface of the aluminum profile, it is ejected onto the deflector plate 7 inside the chassis body 1 and then falls onto the sieve plate 8. The sieve plate 8 blocks the sundries with a volume larger than that of the shot, while the shot falls into the recovery tank 4. The shot in the recovery tank 4 is pushed to the discharge pipe 6 by the screw feeder 5, flows through the discharge pipe 6 into the lifting bucket of the elevator, and the elevator transports the shot to the separator. The shot screened by the separator is then connected to the feed pipe of the spray gun 9 through a pipeline for recycling.
