Description

Technical Field

[0001] The present invention relates to the field of cleaning equipment, and more specifically, to a shot blasting machine shot supply adjusting device. Background Art

[0002] As a common metal cleaning equipment, shot blasting machines are widely used in various fields, such as the cleaning of the decks of steel plate ships and the outer surfaces of large metal storage tanks. The cleaning principle of shot blasting machines is generally the same, that is, through the kinetic energy of steel shots, they are projected onto the metal surface to be cleaned, and the rust on the metal surface is removed by shot blasting.

[0003] For different materials, different degrees of rust on the metal surface, or different metal surface structures, existing shot blasting machines can only clean at a fixed shot blasting speed, which may cause over-cleaning of the metal surface or incomplete cleaning due to a certain curvature of the metal surface.

[0004] Therefore, an adjusting device for a shot blasting machine is needed to solve the above problems. Summary of the Invention

[0005] An object of the present invention is to provide a new technical solution for shot supply adjustment of a shot blasting machine.

[0006] According to a first aspect of the present invention, there is provided a shot blasting machine shot supply adjusting device, including an adjusting cylinder with an open end, the orientation sleeve of the shot blasting machine extends into the adjusting cylinder, an inlet shot hole is opened at the top of the adjusting cylinder, and an outlet shot hole is opened at the bottom of the adjusting cylinder; the closed end of the adjusting cylinder is rotatably connected to a mounting plate, and the adjusting cylinder is mounted on the shot blasting machine through the mounting plate; a first adjusting rod is connected to the closed end of the adjusting cylinder, and a regulator is connected to the end of the first adjusting rod extending into the adjusting cylinder, and the regulator can move in the adjusting cylinder with the movement of the first adjusting rod to block the inlet shot hole.

[0007] Through this solution, by adjusting the length of the first adjusting rod extending into the adjusting cylinder, the area of the inlet shot hole blocked by the regulator can be adjusted, thereby adjusting the amount of iron shots entering the shot blasting wheel, and further adjusting the amount of shots discharged from the outlet shot hole; the steel shots move at high speed along the tangent direction of the shot blasting wheel through the orientation sleeve and fly out of the outlet shot hole. Therefore, when the adjusting cylinder rotates, the orientation of the outlet shot hole changes, which can change the flying angle of the iron shots, thereby controlling the shot blasting angle of the shot blasting machine, and is suitable for cleaning metal surfaces with a certain angle. This device can adjust the shot output and shot blasting angle of the shot blasting machine, so as to adjust according to different materials or the curvature of the surface to be cleaned, and improve the application range of this device.

[0008] Preferably, a force - applying block is fixed to the closed end of the adjusting cylinder. The force - applying block is strip - shaped. A fixator is arranged at one end of the force - applying block, and the fixator is used to fix the relative position of the force - applying block and the mounting plate.

[0009] With this solution, it is convenient to rotate the adjusting cylinder and to fix the adjusting cylinder.

[0010] Preferably, there are two force - applying blocks, and the included angle and the opening direction between the two force - applying blocks are the same as those of the shot - discharging hole.

[0011] With this solution, the orientation of the shot - discharging hole can be obtained intuitively, thus facilitating adjustment.

[0012] Preferably, the first adjusting rod is thread - connected to the center of the closed end of the adjusting cylinder; a handwheel is fixed to the end of the first adjusting rod that is not connected to the adjuster.

[0013] With this solution, rotating the handwheel to adjust the position of the adjuster not only has higher adjustment accuracy but also can ensure the stability of the adjuster position.

[0014] Preferably, the adjuster is a cylindrical structure with one end open, and the closed end of the adjuster is fixed to the first adjusting rod.

[0015] With this solution, the structure is simple, convenient for installation and adjustment, and has good stability; it can adjust the opening sizes of both the shot - inlet hole and the shot - discharging hole simultaneously.

[0016] Preferably, the adjuster includes a shielding plate and a transmission plate. The shielding plate is vertically fixed to the transmission plate; the shielding plate is used to block the shot - inlet hole, the first adjusting rod is rotatably connected to the transmission plate; the shielding plate is slidably connected to the adjusting cylinder.

[0017] With this solution, only the opening size of the shot - inlet hole can be adjusted, so as not to affect the shot - blasting quality of the shot - discharging port, and to avoid the situation that the shot - discharging port is too small to effectively discharge the iron shots, resulting in the retention of iron shots in the adjusting cylinder.

[0018] Preferably, a sliding groove is arranged on the adjusting cylinder, and a sliding strip matched with the sliding groove is arranged on the shielding plate.

[0019] With this solution, the shielding plate is prevented from rotating.

[0020] Preferably, the transmission plate is circular, and the transmission plate is concentric with the adjusting cylinder and has a clearance fit with the adjusting cylinder.

[0021] With this solution, it plays a blocking role to prevent iron shots from remaining in the adjusting cylinder.

[0022] Preferably, at least one guiding plate is hinged at the pill outlet hole, and the hinge axis of the guiding plate is parallel to the axle of the shot blasting wheel; a second adjusting rod is hinged on the guiding plate, and one end of the second adjusting rod extends out of the shot blasting machine.

[0023] With this solution, the angle control of the iron pellets flying out is further improved to ensure the accuracy of the angle.

[0024] Preferably, the guiding plate is connected to the adjusting cylinder through a connecting rod, both ends of the connecting rod are fixed to the adjusting cylinder on both sides of the pill outlet hole, and the guiding plate is hinged to the connecting rod.

[0025] With this solution, the guiding plate can rotate following the adjusting cylinder, further improving the reliability of angle adjustment.

[0026] According to an embodiment of the present disclosure, the shot blasting machine equipped with this adjusting device can be adjusted according to different materials and the rust degree of the metal surface, control the amount of shot and the shot angle, thereby improving the cleaning effect, avoiding the problems of over-cleaning or incomplete cleaning, and this device can be applied to the surface of metal equipment with a certain curvature.

[0040] Embodiment 1

[0041] As Figures 1 to 2 shown, the shot blasting machine shot supply adjusting device in this embodiment includes an adjusting cylinder 1100 with one end open. The orientation sleeve of the shot blasting machine extends into the adjusting cylinder 1100. An inlet shot hole 1110 is formed at the top of the adjusting cylinder 1100, and an outlet shot hole 1120 is formed at the bottom of the adjusting cylinder 1100. The closed end of the adjusting cylinder 1100 is rotatably connected to a mounting plate 1300, and the adjusting cylinder 1100 is mounted to the shot blasting machine through the mounting plate 1300. A first adjusting rod 1210 is connected to the closed end of the adjusting cylinder 1100. One end of the first adjusting rod 1210 extending into the adjusting cylinder 1100 is connected to an adjuster 1220, and the adjuster 1220 can move in the adjusting cylinder 1100 along with the movement of the first adjusting rod 1210 to block the inlet shot hole 1110.

[0042] Through the solution of this embodiment, by adjusting the length of the first adjusting rod 1210 extending into the adjusting cylinder 1100, the area of the inlet shot hole 1110 shielded by the adjuster 1220 can be adjusted, thereby adjusting the number of iron shots entering the shot wheel 2000, and further adjusting the shot output of the outlet shot hole 1120; the iron shots move at a high speed along the tangent direction of the shot wheel 2000 and fly out of the outlet shot hole 1120. Therefore, when the adjusting cylinder 1100 rotates, the change in the orientation of the outlet shot hole 1120 can change the flying angle of the iron shots, thereby controlling the shot angle of the shot blasting machine, which is suitable for cleaning metal surfaces with a certain angle on the surface. This device can adjust the shot output and the shot angle of the shot blasting machine, so that it can be adjusted according to different materials or the curvature of the surface to be cleaned, improving the applicable range of this device.

[0043] In this embodiment, both the length and width of the inlet shot hole 1110 are not less than the length and width of the outlet 1120; during the rotation of the adjusting cylinder 1100, the bottom opening of the shot blasting machine storage bucket is always in communication with the inlet shot hole 1110.

[0044] In this embodiment or other embodiments, a force application block 1130 is fixed to the closed end of the adjusting cylinder 1100. The force application block 1130 is strip-shaped, and a fixator 1131 is provided at one end of the force application block 1130. The fixator 1131 is used to fix the relative position of the force application block 1130 and the mounting plate 1300. It is convenient to rotate the adjusting cylinder 1100 and to fix the adjusting cylinder 1100. During adjustment, the force application block 1130 can be pushed to rotate the adjusting cylinder 1100. This push can be automatic, such as a cylinder, an oil cylinder or a servo electric cylinder, or it can be manually pushed. The fixator 1131 is, for example, a tightening bolt, or a limit device of a cylinder, an oil cylinder or a servo electric cylinder. In this embodiment, the fixator 1131 is a tightening bolt.

[0045] In this embodiment or other embodiments, there are two force application blocks 1130. The included angle and the opening direction of the included angle between the two force application blocks 1130 are the same as those of the outlet shot hole 1120. The orientation of the outlet shot hole 1120 can be intuitively obtained, which is convenient for adjustment.

[0046] In this embodiment or other embodiments, the angles at which the iron shots fly out at any position are pasted on the mounting plate 1300, so as to adjust the angle of the adjusting cylinder 1100, so as to adapt to metal surfaces to be cleaned with different arc surfaces or angles.

[0047] In this embodiment or other embodiments, the first adjusting rod 1210 is threadedly connected to the center of the closed end of the adjusting cylinder 1100; a handwheel 1230 is fixed to one end of the first adjusting rod 1210 that is not connected to the adjuster 1220. Rotating the handwheel 1230 to adjust the position of the adjuster 1220 not only has higher adjustment accuracy but also can ensure the stability of the position of the adjuster 1220. The handwheel 1230 can be manually adjusted or driven by a servo motor to adjust. The servo motor can automatically rotate to a suitable position according to the program setting.

[0048] In this embodiment or other embodiments, the adjuster 1220 is a cylindrical structure with one end open, and the closed end of the adjuster 1220 is fixed to the first adjusting rod 1210. This setting has a simple structure, is convenient for installation and adjustment, and has good stability; it can simultaneously adjust the opening sizes of the shot inlet hole 1110 and the shot outlet hole 1120; the shot blasting wheel 2000 can extend into the opening of the adjuster 1220.

[0049] According to this embodiment, the shot blasting machine equipped with this adjustment device can be adjusted according to different materials and horizontal and vertical surfaces to control the shot output and the shot outlet angle, thereby improving the cleaning effect and avoiding problems such as excessive cleaning or incomplete cleaning. And this device can be applied to the surface of metal equipment with a certain curvature.

[0050] Embodiment Two

[0051] As Figure 3 and Figure 4 shown, the difference between the shot supply adjustment device in this embodiment of the shot blasting machine and the technical solution in the above embodiment is that the adjuster 1220 includes a shielding plate 1221 and a transmission plate 1222, and the shielding plate 1221 is vertically fixed to the transmission plate 1222; the shielding plate 1221 is used to shield the shot inlet hole 1110, and the first adjusting rod 1210 is rotatably connected to the transmission plate 1222; the shielding plate 1221 is slidably connected to the adjusting cylinder 1100.

[0052] Through the solution of this embodiment, only the opening size of the shot inlet hole 1110 can be adjusted, so as not to affect the shot blasting quality of the shot outlet 1120 and avoid the situation that the shot outlet 1120 is too small to effectively eject the iron shots, resulting in the iron shots remaining in the adjusting cylinder 1100; the sliding connection between the shielding plate 1221 and the adjusting cylinder 1100 can prevent the shielding plate 1221 from rotating with the rotation of the first adjusting rod 1210 and losing the function of adjusting the opening size of the shot inlet hole 1110.

[0053] In this embodiment, the length and width of the baffle plate 1221 are both not less than the length and width of the shot inlet hole 1110. One end of the baffle plate 1221 is fixed to the transmission plate 1222. When the baffle plate 1221 completely blocks the shot inlet hole 1110, the transmission plate 1222 cannot block the shot outlet 1120.

[0054] In this embodiment or other embodiments, a sliding groove 1140 is provided on the adjusting cylinder 1100, and a sliding bar 1223 that cooperates with the sliding groove 1140 is provided on the baffle plate 1221. This prevents the baffle plate 1221 from rotating along.

[0055] In this embodiment or other embodiments, the transmission plate 1222 is circular, and the transmission plate 1222 is concentrically arranged with the adjusting cylinder 1100 and has a clearance fit with the adjusting cylinder 1100. It plays a blocking role to prevent iron shots from remaining in the adjusting cylinder 1100.

[0056] The shot supply adjusting device of the shot blasting machine in this embodiment can ensure the shot blasting quality, make the adjustment of the shot output of the shot blasting machine more accurate, and does not affect the cleaning effect.

[0057] Embodiment Three

[0058] As Figure 5 and Figure 6 shown, for the shot supply adjusting device of the shot blasting machine in this embodiment, on the basis of the technical solutions in the above two embodiments, at least one guiding plate 1150 is hinged at the shot outlet 1120, and the hinge axis of the guiding plate 1150 is parallel to the axle of the shot blasting wheel 2000; a second adjusting rod 1151 is hinged on the guiding plate 1150, and one end of the second adjusting rod 1151 extends out of the shot blasting machine.

[0059] With the solution of this embodiment, by pulling the guiding plate 1150 with the second adjusting rod 1151 to adjust the angle of the guiding plate 1150, it can guide the flying iron shots, further improve the control of the angle when the iron shots fly out, and ensure the accuracy of the angle. The second adjusting rod 1151 can be manually adjusted or automatically adjusted.

[0060] In this embodiment or other embodiments, the guiding plate 1150 is connected to the adjusting cylinder 1100 through a connecting rod 1152. Both ends of the connecting rod 1152 are fixed to the adjusting cylinder 1100 on both sides of the shot outlet 1120, and the guiding plate 1150 is hinged to the connecting rod 1152. The guiding plate 1150 can rotate along with the adjusting cylinder 1100, further improving the reliability of the angle adjustment.

[0061] The second adjusting rod 1151 can be hinged to the housing of the shot blasting machine. When rotating the adjusting cylinder 1100, the angle adjustment of the guide plate 1150 can be achieved without adjusting the second adjusting rod 1151.

[0062] The connecting rod 1152 in this embodiment has a certain arc, and the arc is consistent with the arc on the outer periphery of the adjusting cylinder 1100, so that the angle adjustment of the guide plate 1150 will not interfere with the rotation of the shot wheel 2000.

[0063] Although some specific embodiments of the present invention have been described in detail by way of examples, those skilled in the art should understand that the above examples are only for illustration purposes and not for limiting the scope of the present invention. Those skilled in the art should understand that the above embodiments can be modified without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
