Description

Technical Field

[0001] The utility model relates to the technical field of crawler-type shot blasting machines, in particular to a discharging device of a crawler-type shot blasting machine. Background Art

[0002] The crawler shot blasting machine loads workpieces through high-strength wear-resistant rubber tracks or manganese steel tracks, and uses a high-speed rotating impeller to throw projectiles onto the workpieces in the chamber to achieve the purpose of cleaning. By adding a predetermined number of workpieces into the cleaning chamber, after the machine is started, the projectiles thrown out by the shot blasting device at high speed form a stream of projectiles, which evenly hit the surface of the workpiece, thereby achieving the purpose of cleaning and strengthening. The projectiles and sand particles flow into the projectile collecting device, and are lifted by the projectile conveying device to the shot blasting device for re-blasting. Among them, the shot blasting device, projectile collecting device, and projectile conveying device are all mature existing technologies. When discharging, a box body or a separate conveyor belt is usually used to discharge at the discharge port of the cleaning machine.

[0004] Based on the above search and in combination with existing technologies, it was found that the discharge devices of crawler-type shot blasting machines disclosed above generally require the machine to be shut down for centralized transfer and discharge. Otherwise, the material will continue to fall to the ground during the removal of the discharge device, reducing cleaning efficiency. Therefore, a discharge device for a crawler-type shot blasting machine is proposed to improve the above-mentioned problem. Utility Model Content

[0005] The purpose of this application is to provide a discharging device for a crawler-type shot blasting machine to solve the problems raised in the above-mentioned background technology.

[0019] 2. In the present invention, through the setting of the transmission mechanism, the driving motor drives the conveyor crawler to convey the material, and at the same time, the transmission mechanism drives the mounting seat to move the translation frame and the movable frame back and forth horizontally, so that the material can be automatically and evenly spread on the movable frame, and no local accumulation will occur, causing the material to overflow prematurely.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] Example: Reference Figure 1-6 The discharging device of a crawler-type shot blasting machine shown includes a discharging mechanism 3 arranged at the conveying terminal of the cleaning machine 1.

[0030] Specifically, such as Figure 2 、 Figure 3 and Figure 4 The cam 33 is fixed to the upper end of the support frame 31 and is fixed to the upper end of the support frame 31 so as to slide the cam 33 downwards so as to move the cam 33 downwards and thereby move the cam 33 downwards.

[0031] Among them, such as Figure 1 and Figure 2It is shown that a transmission mechanism 4 is provided between the driving motor 5 for driving the conveying action of the conveyor belt 2 on the cleaning machine 1 and the mounting seat 34, so that while the driving motor 5 drives the conveyor belt 2 to convey the material, the mounting seat 34 is driven by the transmission mechanism 4 to move back and forth horizontally with the translation frame 32 and the movable frame 33, so that the material can be automatically and evenly spread in the movable frame 33, and local accumulation will not occur, causing the material to overflow prematurely.

[0032] Regarding the transmission mechanism 4, more specifically, Figure 3 As shown, the transmission mechanism 4 includes a threaded screw 41, a first transmission sprocket 42, a second transmission sprocket 43 and a transmission chain 44. The threaded screw 41 is horizontally rotatably mounted on the upper end of the fixed seat 31. The threaded screw 41 threadably penetrates the mounting seat 34. The first transmission sprocket 42 is coaxially fixed with the output shaft of the drive motor 5. The second transmission sprocket 43 is coaxially fixed with the threaded screw 41. The transmission chain 44 is transmission-connected between the first transmission sprocket 42 and the second transmission sprocket 43.

[0033] The diameter of the first transmission sprocket 42 is smaller than that of the second transmission sprocket 43 , so that the rotation speed of the screw rod 41 is lower than the driving speed of the driving motor 5 , thereby preventing the translation frame 32 from moving too fast and accelerating wear.

[0034] Among them, a limit block 310 is fixed on the side end of the translation frame 32 near its bottom, and the movable frame 33 is placed on the upper end of the limit block 310. The bottom end of the movable frame 33 is set to a mesh shape, and the impurities and pellets carried in the material will fall to the bottom end of the translation frame 32, which is convenient for centralized cleaning later.

[0035] In order to separate the impurities and pellets carried in the material from the material more thoroughly, a fixed plate 39 is vertically installed on the upper end of the fixed seat 31, and a wavy tooth is provided on the upper end of the fixed plate 39. A roller 38 adapted to the wavy tooth is provided at the lower end of the translation frame 32. A compression spring 36 is vertically installed between the mounting seat 34 and the translation frame 32. A limiting column 37 is vertically fixed to the bottom end of the translation frame 32, and a limiting groove 3401 adapted to the limiting column 37 is provided on the upper end of the mounting seat 34. During the horizontal reciprocating movement of the translation frame 32, the roller 38 rolls on the wavy tooth, which can cause the translation frame 32 to bump up and down, thereby shaking off the impurities and pellets carried in the material, and separating the impurities and pellets from the material more thoroughly.

[0036] The working principle of the present invention is as follows: in the process of the driving motor 5 driving the conveying crawler 2 to convey the material, the cleaned material is discharged into the movable frame 33. At the same time, the driving motor 5 drives the mounting seat 34 through the transmission mechanism 4 to carry the translation frame 32 and the movable frame 33 to move back and forth horizontally, so that the material can be automatically and evenly spread in the movable frame 33, and no local accumulation will occur to cause the material to overflow prematurely. In the process of the horizontal reciprocating movement of the translation frame 32, the roller 38 rolls on the wave teeth, which can make the translation frame 32 bump up and down, thereby shaking off the impurities and pellets carried in the material, and the impurities and pellets are separated from the material more thoroughly. The impurities and pellets carried in the material will fall to the bottom of the translation frame 32, which is convenient for centralized cleaning later. In the process of centralized transfer of one of the movable frames 33, the material can continue to fall into the other movable frame 33 without stopping, thereby ensuring the efficiency of the cleaning operation.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
