Description

Technical Field

[0001] The invention relates to the technical field of material conveying, in particular to a shot conveying mechanism for a shot blasting machine. Background Art

[0002] Shot blasting machine is a casting equipment that uses high-speed projectiles thrown by the shot blaster to clean or strengthen the surface of castings. The projectiles used are generally small-grained steel shots, which need to circulate throughout the machine. For this purpose, a mechanism for conveying the shot is required to achieve the conveying of the shot.

[0003] The patent application with application number CN202321612576.4 discloses a shot conveying mechanism for a shot blasting machine, including a spiral blade on a central shaft and an outer wall thereof, and also including a first shaft head and a second shaft head respectively connected to both ends of the central shaft, the ends of the first shaft head and the second shaft head respectively extend into the openings at both ends of the central shaft and are fixedly connected to the central shaft, and also includes a shield, which is a truncated cone-shaped hollow structure and is respectively covered at the connection between the first shaft head and the second shaft head and the central shaft, the large heads of the two shields are arranged far away from each other, and the small heads of the shields abut the ends of the spiral blades, the weight of the spiral central shaft can be greatly reduced by the hollow central shaft, and more energy is saved when conveying the pellets, and the conveyed pellets are effectively shielded at both ends of the conveying mechanism to prevent the pellets from overflowing to both ends, and to prevent the material from overflowing to both ends, and to reduce the situation of material blockage, so as to effectively realize the pellet conveying of the shot blasting machine and ensure the supply of pellets.

[0004] When the existing equipment is in use, the classified shots are usually transported back to the top of the equipment through a screw conveyor or a bucket elevator. However, due to the small size of the shots, a large amount of shot residue will remain in the lifting device. Such accumulation of shots may get stuck in the operating structure of the equipment, affecting the normal operation of the equipment and being detrimental to the normal use of the equipment. Summary of the invention

[0005] The object of the present invention is to provide a shot conveying mechanism for a shot blasting machine to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions: a shot conveying mechanism for a shot blasting machine, comprising a bottom plate, a top of which is fixedly connected to an operating table, and further comprising: The lifting mechanism comprises a shell fixedly connected to the top of the base plate, the inner wall of the shell is fixedly connected to a driving device, and the inner wall of the driving device is movably connected to a transport component.

[0007] According to the above technical solution, an elastic component 1 is fixedly connected to the inner wall of the shell, and a friction plate 1 is fixedly connected to the end of the elastic component 1 away from the shell. The elastic component 1 is used to push the friction plate 1 forward, so that the friction plate 1 can apply sufficient pressure to the friction plate 2 to ensure that the transport component can be stopped briefly.

[0008] According to the above technical solution, the transport component includes a connecting plate 1, the outer wall of the connecting plate 1 is movably connected to the driving device, the end of the connecting plate 1 away from the starting device is fixedly connected to a support plate, the side of the support plate away from the connecting plate 1 is fixedly connected to a connecting plate 2, and the end of the connecting plate 2 away from the support plate is fixedly connected to a slider.

[0009] According to the above technical solution, a base is provided on the side of the support plate away from the connecting plate 1, and a slide groove is provided on the side of the base close to the support plate. The inner wall of the slide groove is movably connected to the slider, and the inner wall of the slide groove is fixedly connected to an elastic component 2, and the top of the elastic component 2 is fixedly connected to the slider. Through the elastic component 2, there is a movable space between the sliding frame connected to the transport component and the base, ensuring that the transport component can stop briefly.

[0010] According to the above technical solution, a right-angle groove is provided on the outer wall of the base. By arranging the right-angle groove on the base, the shot entering the device can directly enter the right-angle groove. During the rising process of the base, the inflection point of the right-angle groove is lower than the entrance. After the shot enters the right-angle groove, it will accumulate at the lowest point of the right-angle groove under the action of its own weight, so as to prevent the shot from being scattered to other places in the equipment and ensure the normal transportation of the equipment. When the transport component needs to unload the shot, the inlet and outlet of the right-angle groove will be lower than the inflection point, and the shot will be automatically discharged from the right-angle groove. The right-angle groove runs through the base, and the base is away from the support plate. A friction plate 2 is fixedly connected to the side, and the outer wall of the friction plate 2 is movably connected to the friction plate 1. By arranging the friction plate 1 and the friction plate 2, when the right-angle groove on the base moves to the vicinity of the through hole, due to the friction between the friction plate 1 and the friction plate 2, the base cannot move in a short time until the elastic component 2 is fully extended, and then the base will be driven to continue to move. Such an arrangement allows the right-angle groove to pause for a period of time in front of the through hole, making it convenient for the equipment to deliver the pill body into the base, while reducing the distance between the next transport component and the through hole, avoiding the pill body from leaking into the equipment during the switching of the transport component, and ensuring the stability of the equipment operation.

[0011] According to the above technical solution, the outer wall of the base is movably connected to the shell. Since the outer wall of the base is movably connected to the inner wall of the shell, the inlet and outlet of the right-angle groove are fitted on the inner wall of the shell, so that when the equipment is working, there is no leakage of the pill from the right-angle groove, ensuring the stable operation of the equipment. Notches are provided on both sides of the bottom of the base, and raised plates are fixedly connected on both sides of the top of the base. The outer wall of the raised plate is movably connected to the notch, and the outer wall of the raised plate is movably connected to the shell. By setting the notch and the raised plate, although the friction plate 1 and the friction plate 2 reduce the distance between the two transport components, the upper transport component is no longer controlled by the friction plate 1, and will rise rapidly under the drive of the elastic component 2. At this short time point, a gap will still be generated in front of the through hole to cause the pill to leak. Therefore, when the upper transport component is detained, the raised plate of the lower transport component will be embedded in the notch of the upper transport component. In this way, after the upper transport component leaves, the outlet of the through hole will be blocked by the raised plate to prevent the pill from leaking into the equipment, ensuring the stable operation of the equipment.

[0012] According to the above technical solution, a cavity one is opened on the inner side of the shell, the entrance of the cavity one is fixedly connected to the feed port, the inner wall of the cavity one is opened with a through hole, the through hole penetrates the shell and extends to the inner wall of the shell, when the pill body is lifted during operation, the pill body is transported to the cavity one through the feed port, and then sent to the transport component through the through hole. This arrangement can prevent the pill body from contacting the running part of the equipment, prevent the pill body from leaking into the equipment, and ensure the stability of the equipment operation.

[0013] According to the above technical solution, a second cavity is further provided on the inner side of the shell, the entrance of the second cavity is fixedly connected to a discharge port, an arc groove is provided on the inner wall of the second cavity, the arc groove passes through the shell and extends to the inner wall of the shell, wherein the arc groove is used to allow the pills stored in the transport component to fall into the second cavity through the arc groove, such a setting can prevent the pills from contacting the running parts of the equipment, prevent the pills from leaking into the equipment, and ensure the stability of the equipment operation.

[0014] Compared with the prior art, the beneficial effects achieved by the present invention are: 1. The present invention arranges a right-angle groove on the base so that the shot entering the device directly enters the right-angle groove. During the rising process of the base, the inflection point of the right-angle groove is lower than the entrance. After the shot enters the right-angle groove, it will accumulate at the lowest point of the right-angle groove under the action of its own weight, avoiding the shot from scattering to other places in the equipment, ensuring the normal transportation of the equipment. When the transport component needs to unload the shot, the inlet and outlet of the right-angle groove will be lower than the inflection point, and the shot will be automatically discharged from the right-angle groove.

[0015] 2. The present invention arranges friction plates 1 and 2. When the right-angle groove on the base moves to the vicinity of the through hole, the friction between the friction plates 1 and 2 prevents the base from moving in a short time until the elastic component 2 is fully extended, which drives the base to continue moving. This arrangement allows the right-angle groove to pause for a period of time in front of the through hole, making it convenient for the device to deliver the pill into the base, while reducing the distance between the next transport component and the through hole, avoiding pill leakage into the device during the switching of the transport component, and ensuring the stability of the equipment operation.

[0016] 3. The present invention provides a notch and a raised plate. Although the friction plate 1 and the friction plate 2 reduce the distance between the two transport components, the upper transport component is no longer controlled by the friction plate 1 and will rise rapidly under the drive of the elastic component 2. During this short period of time, a gap will still be generated in front of the through hole to cause the pill to leak. Therefore, when the upper transport component is detained, the raised plate of the lower transport component will be embedded in the notch of the upper transport component. In this way, after the upper transport component leaves, the outlet of the through hole will be blocked by the raised plate to prevent the pill from leaking into the equipment, thereby ensuring the stability of the equipment operation.

[0017] 4. In the present invention, since the outer wall of the base is movably connected to the inner wall of the shell, the inlet and outlet of the right-angle groove are fitted on the inner wall of the shell, which can prevent the pill from leaking from the right-angle groove when the equipment is working, thereby ensuring the stable operation of the equipment. At the same time, only when the inlet and outlet of the right-angle groove coincide with the through hole of the arc-shaped groove box, can the pill enter and exit the right-angle groove, and the pill entering and exiting the transport component can enter and exit the equipment through cavity one and cavity two. This arrangement can prevent the pill from contacting the operating part of the equipment, prevent the pill from leaking into the equipment, and ensure the stable operation of the equipment.

[0020] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0021] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] Example 1: See Figure 1-Figure 5 The present invention provides a technical solution: a shot conveying mechanism for a shot blasting machine, comprising a bottom plate 1, a top of the bottom plate 1 is fixedly connected with an operating table 101, and further comprising: The lifting mechanism 2 comprises a shell 201 fixedly connected to the top of the base plate 1, the inner wall of the shell 201 is fixedly connected with a driving device 207, the inner wall of the driving device 207 is movably connected with a transport component 21, a cavity 204 is provided on the inner side of the shell 201, the entrance of the cavity 204 is fixedly connected with a feed port 202, a through hole 208 is provided on the inner wall of the cavity 204, the through hole 208 penetrates the shell 201 and extends to the inner wall of the shell 201, a cavity 205 is also provided on the inner side of the shell 201, the entrance of the cavity 205 is fixedly connected with a discharge port 203, an arc groove 206 is provided on the inner wall of the cavity 205, the arc groove 206 penetrates the shell 201 and extends to the inner wall of the shell 201, the inner wall of the shell 201 is fixedly connected with an elastic component 209, and the end of the elastic component 209 away from the shell 201 is fixedly connected with a friction plate 2010.

[0023] The working principle of this embodiment is as follows: after the equipment has shot blasted the metal, the pills will be filtered and separated, and then the pills will be fed into the equipment through the feed port 202. When the pills enter the equipment through the feed port 202, they will first accumulate in the cavity one 204. Since the inner wall of the cavity one 204 is inclined, the pills will move away from the feed port 202. Then the driving device 207 will be started to drive the transport component 21 to move, and the pills in the cavity one 204 will be fed into the transport component 21 through the through hole 208. As the transport component 21 moves, when the transport component 21 moves to the position of the arc groove 206, the pills in the transport component 21 will fall into the cavity two 205 through the arc groove 206. At this time, the pills in the cavity two 205 will be discharged from the equipment through the discharge port 203.

[0024] Example 2: Based on Example 1, please refer to Figure 6-Figure 9The transport component 21 includes a connecting plate 211, the outer wall of the connecting plate 211 is movably connected to the driving device 207, the end of the connecting plate 211 away from the starting device is fixedly connected to the support plate 212, the side of the support plate 212 away from the connecting plate 211 is fixedly connected to the connecting plate 213, the end of the connecting plate 213 away from the support plate 212 is fixedly connected to the slider 214, the side of the support plate 212 away from the connecting plate 211 is provided with a base 215, the side of the base 215 close to the support plate 212 is provided with a slide groove 216, the inner wall of the slide groove 216 is movably connected to the slider 214, the inner wall of the slide groove 216 is fixedly connected to the elastic component 217, the elastic component 217 The top of the base 215 is fixedly connected to the slider 214, and the outer wall of the base 215 is provided with a right-angle groove 2110. When the base 215 is at the front end of the through-hole, the inflection point of the right-angle groove 2110 is lower than the entrance. After the shot enters the right-angle groove 2110, it will accumulate at the lowest point of the right-angle groove 2110 under the action of its own weight, so as to prevent the shot from scattering to other places in the equipment. When the transport component 21 moves to the arc groove 206 driven by the driving device 207, the inlet and outlet of the right-angle groove 2110 will be lower than the inflection point. At this time, the shot will be automatically discharged from the right-angle groove 2110 under its own weight and the inertia of the base 215. The right-angle groove 2110 penetrates the base 215, and the base 2 A friction plate 2111 is fixedly connected to one side of the support plate 215 away from the support plate 212, and the outer wall of the friction plate 2111 is movably connected to the friction plate 1 2010. The outer wall of the base 215 is movably connected to the housing 201. Notches 219 are provided on both sides of the bottom of the base 215, and raised plates 218 are fixedly connected to both sides of the top of the base 215. The outer wall of the raised plate 218 is movably connected to the notch 219. When the transport component 21 moves to the through-hole, the friction plate 1 2010 will apply pressure to the friction plate 2111, thereby preventing the base 215 from continuing to move upward, but the driving device 207 still moves normally. With the operation of the driving device 207, the transport component 21 located below still moves upward. It will move upward normally. With the movement of the lower transport component 21, the raised plate 218 on the lower base 215 will be embedded in the notch 219 of the upper base 215. Then the upper and lower bases 215 will move upward together until the friction plate 1 2010 no longer applies pressure to the friction plate 2111. The upper base 215 will move upward under the elastic force of the elastic component 217. At this short point in time, a gap will be generated between the upper and lower bases 215. However, at this time, the outlet of the through hole 208 has been blocked by the raised plate 218 on the lower base 215 to prevent the pill from leaking into the equipment and ensure the stable operation of the equipment. The outer wall of the raised plate 218 is movably connected to the outer shell 201.

[0025] The working principle of this embodiment is as follows: when the transport component 21 moves to the through-hole, the friction plate 1 2010 will exert pressure on the friction plate 2111, thereby preventing the base 215 from continuing to move upward. At this time, the ball in the through-hole 208 will move into the right-angle groove 2110. At this time, the ball entering the right-angle groove 2110 will fall into the inflection point of the right-angle groove 2110 under the influence of its own weight. At the same time, the base 215 cannot rise under the pressure of the friction plate 2 and the friction plate 1 2010, but the driving device 207 still moves normally. With the operation of the driving device 207, the connecting plate 1 211 will continue to rise, and the rising connecting plate 1 211 will drive the connecting plate 213 to move upward through the supporting plate, and the moving connecting plate 213 will drive the slider 214 to move upward along the slide groove 216 until the slider 214 moves to the top of the slide groove 216. At this time, the slider 214 will directly pull the base 215 to move upward. As the base 215 moves upward, the friction plate 1 2010 will no longer apply pressure to the friction plate 2111. Therefore, under the elastic force of the elastic component, the base 215 will reset, and then the driving component will drive the transport component 21 to move to the arc groove 206. At this time, the balls in the right-angle groove 2110 will be discharged from it and fall into the cavity 205.
