[0028] In order to have a clearer understanding of the technical features, purposes and effects of the utility model, the specific implementation methods of the utility model are now described with reference to the accompanying drawings.

[0029] like Figure 1-Figure 4 As shown, the utility model provides a thick steel plate shot blasting and rust removal equipment, including a shot blasting chamber 5 and a shot blasting sliding trolley 9, the top of the shot blasting chamber 5 is provided with a shot blasting machine 7; it also includes a circulating feeding system, and the circulating feeding system feeds the shot blasting machine 7.

[0030] The side of the shot blasting chamber 5 is provided with an entrance and exit for the sliding trolley 9 to pass through, and the sliding trolley 9 is arranged obliquely so that the steel shot hits the steel plate on the sliding trolley 9 obliquely.

[0031] The shot blasting chamber 5 has entrances and exits on both sides thereof. The sliding trolley 9 carries the steel plate to enter the shot blasting chamber 5 from the entrance on one side for shot blasting and rust removal. After the operation is completed, the sliding trolley 9 slides out from the entrance on the other side for unloading.

[0032] The steel plate is placed on an inclined sliding trolley 9 and passes through the shot blasting chamber 5 at a certain angle. The steel shots flow down along the steel plate under the action of gravity. The steel plate is not easy to focus the steel shots, which ensures that the steel shots all hit the surface of the steel plate, reduces the mutual collision of the steel shots, and can improve the rust removal quality.

[0033] The utility model also includes a sliding frame 8, and a sliding rail 12 is respectively provided on both sides of the sliding frame 8, and the two sliding rails 12 have a certain height difference in the horizontal direction; a roller 901 is provided at the lower end of the sliding trolley 9, and the roller 901 cooperates with the sliding rail 12 to make the sliding trolley 9 slide obliquely on the sliding frame 8.

[0034] A pulley support rod 10 is installed at both ends of the sliding frame 8, and pulleys 11 are installed at the upper and lower ends of the pulley support rod 10. Steel wire ropes 14 are connected to both sides of the sliding trolley 9. The steel wire ropes 14 on both sides are respectively passed around the pulleys 11 on both sides of the sliding frame 8 and then wound on the winder 13. The winder 13 can pull the steel wire rope 14 on one side while loosening the steel wire rope 14 on the other side, thereby pulling the sliding trolley 9 to slide on the sliding frame 8.

[0035] The shot blasting chamber 5 is tilted, and its tilt angle is the same as the tilt angle of the sliding trolley.

[0036] A plurality of shot blasting machines 7 are arranged on the top of the shot blasting chamber 5 in a direction perpendicular to the sliding direction of the sliding trolley 9. When the sliding trolley 9 enters the shot blasting chamber 5, each shot blasting machine 7 is at an equal distance from the steel plate, so that the steel shots hit the steel plate at the same time.
