DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figure 1As shown, a shot blasting device for steel includes a shot blasting box 1, an opening and closing door 2 is symmetrically rotatably connected to the lower front side of the outer surface of the shot blasting box 1, and the front ends of the outer surfaces of the two opening and closing doors 2 are fixedly connected to handles 3, a motor 4 is fixedly connected to the middle of the upper end of the outer surface of the shot blasting box 1, and a shot blasting mechanism 6 is fixedly connected to the output end of the piston rod of the motor 4, which can realize the effect of high-speed throwing of steel shots, and a feeding mechanism 5 is symmetrically fixedly connected to the left and right sides of the upper inner cavity of the shot blasting box 1, which can realize the effect of conveying steel shots, and a guide is symmetrically fixedly connected to the left and right walls of the middle inner cavity of the shot blasting box 1. The direction mechanism 7 can change the movement direction of the high-speed thrown steel shots. The lower part of the inner cavity of the shot blasting box 1 is fixedly connected to a limiting mechanism 8, which can place the steel in batches. The lower part of the limiting mechanism 8 is movably connected to a supporting mechanism 9, which can support the steel. The left and right sides of the outer side of the supporting mechanism 9 are respectively slidably connected to the left and right walls of the inner cavity of the shot blasting box 1. The bottom wall of the inner cavity of the shot blasting box 1 is slidably connected to a recovery mechanism 10, which can centrally recover the oxide scale and other waste chips that fall off during the impact on the steel.

[0024] In order to achieve the purpose of conveying steel shots, refer to Figure 2 The feeding mechanism 5 includes a fixed tube 51, the upper end of the outer surface of the fixed tube 51 is fixedly connected to a feeding funnel 52, the lower end of the outer surface of the fixed tube 51 is fixedly connected to a discharge pipe 53, and the lower part of the outer surface of the fixed tube 51 is fixedly connected to the upper part of the inner cavity of the shot blasting box 1.

[0025] After the steel shot is placed in the inner cavity of the feed funnel 52 , the steel shot will perform free fall along the inner cavity of the fixed tube 51 , during which the steel shot will obtain a certain initial velocity and finally rush out of the inner cavity of the discharge pipe 53 to reach the upper part of the impeller 63 .

[0026] In order to achieve the purpose of high-speed throwing of steel shots, refer to Figure 2 The shot blasting mechanism 6 includes a flange 61, which can realize the fixed connection between the connecting shaft 62 and the piston rod output end of the motor 4. The lower part of the inner cavity of the flange 61 is fixedly connected with the connecting shaft 62, and the lower end of the outer surface of the connecting shaft 62 is fixedly connected with the impeller 63, which can realize the effect of throwing the steel shot during high-speed rotation. The upper part of the inner cavity of the flange 61 is fixedly connected to the piston rod output end of the motor 4.

[0027] When the steel shot rushing out of the inner cavity of the discharge pipe 53 falls into the inner cavity at the upper part of the impeller 63, the blades of the impeller 63 rotating at high speed will further accelerate the steel shot and finally eject it at high speed.

[0028] In order to change the direction of motion of the high-speed steel shot, refer to Figure 2The guide mechanism 7 includes a plastic fixing plate 71, which can ensure that when the high-speed projectiles hit the outer surface of the arc seat 72, the arc seat 72 has a certain buffering force, thereby preventing the arc seat 72 from being damaged by the steel shots projected at high speed for many times. The outer surface of the plastic fixing plate 71 is fixedly connected to the arc seat 72 at one end close to the middle of the inner cavity of the shot blasting box 1.

[0029] When the steel shot ejected at high speed by the impeller 63 hits the inner surface of the arc seat 72, the steel shot will quickly move in a circular motion downward along the inner surface of the arc seat 72 until it rolls out of the inner cavity of the arc seat 72 and hits the surface of the steel.

[0030] In order to achieve the purpose of placing steel in batches, refer to Figure 3 The limiting mechanism 8 includes a connecting column 81, and a plurality of limiting strips 82 are fixedly connected in an annular array at the lower portion of the outer surface of the connecting column 81. The ends of the plurality of limiting strips 82 that are away from each other are fixedly connected to the inner surface of the shot blasting box 1.

[0031] When the steel shot impacts the surfaces of multiple steel materials, the multiple steel materials will collide and move with each other. Limiting them to a certain extent by the limit strip 82 can make the impact of the steel shot on each steel material more sufficient and accurate.

[0032] In order to achieve the purpose of supporting the steel, refer to Figure 3 The support mechanism 9 includes a support frame 91. A plurality of steel wire grooves 92 communicating with the outside are provided in a circular array on the upper portion of the outer surface of the support frame 91, which can support the steel while allowing the oxide scale and other waste debris that fall off during the impact process to fall downward into the inner cavity of the conical leak hole 102. A through groove 1 93 communicating with the outside is provided in the middle of the front end of the outer surface of the support frame 91. A handle 2 94 is fixedly connected to the bottom wall of the inner cavity of the through groove 1 93, which can be used to pull out the support frame 91 after the shot blasting work is completed to clean up the impurities remaining in the inner cavity of the steel wire groove 92. The left and right ends of the outer surface of the support frame 91 are slidably connected to the lower part of the inner cavity of the shot blasting box 1.

[0033] In order to realize the purpose of centralized recovery of the scale and other waste chips that fall off during the impact of steel, refer to Figure 4 The recovery mechanism 10 includes a recovery box 101, and a conical leakage hole 102 communicating with the outside is opened in the middle of the recovery box 101, which can realize the function of waste chips falling from the inner cavity of the wire groove 92 sliding down along the outer surface of the conical leakage hole 102 to the inner cavity for collection, and the lower end of the outer surface of the recovery box 101 is slidably connected with the bottom wall of the inner cavity of the shot blasting box 1.

[0034] It should be noted that the specific installation method of the motor 4, the circuit connection method and the control method in the present invention are all conventional designs and will not be elaborated in detail in the present invention.

[0035] The working principle of the utility model is as follows: first, steel materials are placed in batches in the inner cavities of several steel wire grooves 92, the power supply of the motor 4 is turned on, and then steel shots are placed in the inner cavity of the feed funnel 52. The steel shots will perform free fall along the inner cavity of the fixed tube 51, during which the steel shots will obtain a certain initial velocity, and finally rush out of the inner cavity of the discharge pipe 53 to reach the upper part of the impeller 63. At this time, the blades of the impeller 63 rotating at high speed will further accelerate the steel shots, and finally eject them at high speed. When the steel shots ejected at high speed hit the inner surface of the arc seat 72, the steel shots will quickly perform circular motion downward along the inner surface of the arc seat 72 until the steel shots are ejected. Until it rolls out of the inner cavity of the arc seat 72 and hits the surface of the steel. At the same time, when the steel shot impacts the surfaces of multiple steels, multiple steels will collide and move with each other, and the limit strip 82 can limit it, so that the steel shot can hit all the placed steels more fully and accurately. During this period, the waste chips falling from the inner cavity of the steel wire groove 92 will slide down along the outer surface of the conical leakage hole 102 to the inner cavity for collection. After completing the shot blasting work, the corresponding opening and closing door 2 is opened through the two handles 1 3, and then the support frame 91 is pulled out of the inner cavity of the shot blasting box 1 through the handle 2 94, and the impurities remaining in the inner cavities of several steel wire grooves 92 are cleaned.

Those skilled in the art should understand that the utility model is not limited by the above embodiments.
