Examples

Referring to fig. 1 and 2, the hand-held shot blasting processing equipment provided by this embodiment includes a hand-held mechanism 2, a traveling frame 3, and a shot blasting structure body 1 having a bounce bin 12, a separation bin 13, and a shot blasting chamber 11, wherein the hand-held mechanism 2 and the traveling frame 3 are respectively disposed at two sides of the shot blasting structure body 1 to achieve the purpose of an operator holding and guiding the shot blasting structure body 1 to travel, three major parts of the bounce bin 12, the separation bin 13, and the shot blasting chamber 11 constitute a main body of the shot blasting structure, steel shots or shots are thrown to a V-shaped impact port formed between the shot blasting chamber 11 and the bounce bin 12 at a high speed by a head assembly 37 in the shot blasting chamber 11, the shots and a surface to be processed are impacted at a high speed and then reach the purpose of surface processing, and thereafter the shots and impurities enter the separation bin 13 from the bounce bin 12 by a reverse elasticity and a high-pressure negative suction force, and the impurities are sucked into a dust removal pipe by a dust, so as to achieve the purpose of separating the pill material from the impurities. Then the shot falls into the bottom of the separation bin 13 under the action of self gravity and blocking force to enter the next circulation, a shot valve 4 with the control function is arranged between the separation bin 13 and the shot blasting chamber 11, the shot valve 4 is in an open state during operation, and the shot falling to the bottom of the separation bin 13 smoothly further falls back into the shot blasting chamber 11 through the shot valve 4 to continue high-speed shot blasting operation.

In actual construction, the whole handheld shot blasting processing equipment needs an operator to hold the shot constantly to keep correct direction guidance, and the conventional handheld shot blasting machine is too long, so that the difficulty of the operator is increased, the operation is not particularly convenient, and the deviation phenomenon of a preset travelling track is easy to occur. The main reason for the overlong length is that the distance between the traveling support frame and the whole shot blasting structure body 1 is overlong, and the motor for driving the shot blasting head assembly 37 has a large volume, so that a space for installing the motor (directly connected with a driven mechanism) needs to be provided, and a long connecting rod needs to be added between the traveling support frame and the shot blasting structure body 1, so that the length of the whole shot blasting structure is overlong. In order to overcome the problem, the inventor of the present application, through a new innovative design, please refer to fig. 5, where the traveling frame 3 includes a support plate 31 and a roller assembly 32, the support plate 31 is installed on the upper portion of the housing of the blasting chamber 11 through a fastener such as a bolt or a rivet, and the conventional connection mode through a long support rod is replaced by the direct connection mode, so that the length of the entire machine is greatly shortened, the traveling frame 3 is closer to the blasting structure body 1, and the operation of an operator is facilitated.

The upper end of the support plate 31 inclines towards one side far away from the shot blasting structure body 1, so that a large space is reserved at the upper part, the power motor 33 with the adjustable up-down position is mounted on the support plate 31, the power motor 33 is mounted in the space between the upper part of the support plate 31 and the shot blasting structure body 1, and the problem that the distance between the support plate 31 and the shot blasting structure body 1 needs to be increased due to the fact that the size of the power motor 33 is too large is solved. In addition, the middle part of the support plate 31 is fixed with a partition plate 38 directly connected with the top wall of the shell of the shot blasting chamber 11, the partition plate 38 has the effect that firstly, the connection strength of the whole support plate 31 is increased, the partition plate is similar to the effect of a reinforcing rib, secondly, the partition plate plays a certain role in partition, and the rotary shaft part of the shot blasting head assembly 37 can be shielded to some extent so as to prevent the rotary shaft work of the shot blasting head assembly 37 from being influenced by external substances too much. Flanges are formed on two sides of the support plate 31, and the purpose of the flanges is to increase the shearing resistance of the whole support plate 31.

The power motor 33 is connected with the shot blasting head assembly 37 in the shot blasting chamber 11 through the transmission assembly 34, of course, the transmission assembly 34 can adopt a belt pulley assembly and also can adopt a chain wheel assembly, and the belt pulley assembly is adopted for optimal transmission due to the advantage of main high-speed transmission. The driving wheel and the driven wheel in the transmission assembly 34 are designed in a top-bottom mode, so that the upper power motor 33 drives the lower shot blasting head assembly 37 to synchronously move. In order to increase the tensioning degree of the transmission belt in the transmission assembly 34, that is, to indicate that the up-down position of the power motor 33 can be adjusted to a certain degree, specifically, the housing (connecting flange) of the power motor 33 is connected with the upper portion of the bracket plate 31 through a plurality of locking bolts, taking the installation mode of a single locking bolt as an example, one end of the locking bolt passes through the locking screw hole 35 of the housing flange of the power motor 33 and the hole of the bracket plate 31 and is matched with a locking nut, so as to achieve the purpose of locking the housing flange of the power motor 33 and the bracket plate 31 to each other, the locking bolt passes through the hole of the bracket plate 31 as a strip-shaped hole 36, the length direction of the strip-shaped hole 36 is arranged along the top-bottom direction of the bracket plate 31, so that the locking bolt can slide up and down along the strip-shaped hole 36 to achieve the purpose.

Because the separation bin 13 can be connected with the dust removal pipe for connect the purpose of follow-up dust removal system in order to reach the impurity separation and retrieve, traditional dust removal union coupling is on the lateral wall of separation bin 13 and is kept away from bounce bin 12 connector, thereby reaches the purpose of smoothly retrieving impurity. After moving up power motor 33, can influence the connection mounted position of dust removal pipe, please refer to fig. 2 again in order to overcome this problem, separation bin 13 upper portion of throwing ball structure body 1 is fixed with dust removal connecting pipe 15, and dust removal connecting pipe 15 includes interconnect's bracing section 151 and linkage segment 152, bracing section 151 one end and separation bin 13 fixed connection and with the inner chamber intercommunication of separation bin 13, and the bracing section 151 other end towards keeping away from blast chamber 11 one side slope, linkage segment 152 is located power motor 33's top, and this kind of design has avoided power motor 33 completely can carry out the problem of position interference, still can not influence the smooth and easy absorption function of impurity simultaneously. Of course, considering that the tube body of the dust removal tube does not affect the normal work of the power motor 33, the upper part of the support plate 31 is provided with the mounting platform, the purpose of limiting the tube body from falling down to affect the power motor 33 can be achieved through the mounting tube fixer, the tube fixer can adopt a quick connecting piece or a general fastener structure, and the purpose of simply and stably fixing the tube body only needs to be achieved. Certainly, in order to ensure that the gravity center of the whole machine is located at the middle position, the control box 5 is fixed on the shell of the bounce bin 12 through the support, and the control box 5 is used for integrating the electric part of the whole machine.

The roller assembly 32 is installed at the lower part of the housing of the blasting chamber 11 and/or the lower part of the support plate 31, that is, the roller assembly 32 can be installed at the lower part of the housing of the blasting chamber 11 or the lower part of the support plate 31, or connected with the lower parts of the housing and the support plate, and only the purposes of stable movement and convenient operation need to be achieved. Referring to fig. 6, the roller assembly 32 includes two sets of roller mechanisms disposed on two sides of the supporting plate 31, that is, two sets of roller mechanisms are respectively disposed on two sides of the supporting plate 31 for supporting and moving. The description will be made by taking a single set of roller mechanism as an example, the roller mechanism includes a support rod 321 and an adjusting support rod 322, the support rod 321 is fixed at the lower part of the housing of the blasting chamber 11 and/or the lower part of the support plate 31, similarly, the support rod 321 may be fixed at the lower part of the housing of the blasting chamber 11 or the lower part of the support plate 31, or may be fixedly connected with the lower parts of both, in this embodiment, the support rod 321 is fixedly connected with the lower part of the housing of the blasting chamber 11 and the lower part of the support plate 31 through a reinforcing plate or a reinforcing rib. The adjusting rod 322 is connected to the supporting rod 321 through an adjusting bolt, and the adjusting rod 322 can adjust the relative distance between the adjusting rod and the supporting rod 321 through the adjusting bolt, that is, the adjusting bolt hole 324 is formed in the supporting rod, the adjusting bolt hole 324 is internally matched with the adjusting bolt, the other end of the adjusting bolt is connected to the adjusting rod 321, the adjusting bolt is rotated to change the distance between the supporting rod 321 and the adjusting rod 322, and the distance refers to the vertical distance. The adjusting support rod 322 is rotatably provided with a roller 323, and the relative distance between the roller 322 and the support plate 31 is changed by changing the vertical position of the adjusting support rod 322, so as to achieve the purpose of adjusting the distance between the V-shaped impact port and the surface to be treated.

In order to ensure that the adjusting support rod 322 and the support rod 321 have high connection stability on the premise of relative adjustability, in this embodiment, sliding holes distributed along the axial direction of the support rod 321 are processed in the support rod 321, and the sliding holes may be in the form of through holes or blind holes. One end of the adjusting support rod 322 movably penetrates into a sliding hole of the support rod 321, the adjusting support rod 322 can move up and down or swing relative to the sliding hole of the support rod 321, the adjusting bolt is screwed on the upper surface of the support rod 321 and used for limiting the adjusting support rod 322 to move up, namely, one end of the adjusting bolt inserted into the sliding hole is abutted against the upper surface of the adjusting support rod 322, so that the roller 323 cannot further move up under the limit of the adjusting bolt after receiving ground supporting force, and the purpose of adjusting the up and down moving position of the adjusting support rod 322 through the adjusting bolt is achieved. An anti-falling screw hole 325 is processed on the side wall of the support rod 321, an anti-falling bolt is matched in the anti-falling screw hole 325, and the anti-falling bolt is used for preventing the adjusting support rod 322 from being separated from the sliding hole. Specifically, a sliding groove running up and down can be processed on the side wall of the adjusting support rod 322, and the end of the anti-falling bolt penetrates through the anti-falling screw hole and then penetrates into the sliding groove, so that the limiting effect is formed, and the purpose of preventing the adjusting support rod 322 from being separated from the sliding hole is achieved.

Because the bottom of the separation bin 13 of the traditional shot blasting structure body 1 adopts the conventional design, only how to make the shot fall to a certain position of the bottom of the separation bin 13 in a centralized manner is considered, then the centralized position is connected with the feeding end of the shot valve 4, and then the discharging end of the shot valve 4 is led to and connected with the feeding pipe of the shot blasting chamber 11, although the steel shot can be timely recovered, the bent pipe type shot valve 4 is often adopted to play a connection control role, namely, the pipe body of the shot valve 4 is in a bent pipe shape, and the control structure part is integrated at the bent position of the bent pipe. The design of the elbow only considers the problems of preliminary buffering the pills and ensuring smooth circulation of the pills, but the pills impacted at high speed often directly fall to the bottom of the separating bin 13 and directly enter the feeding end of the pill valve 4, so that overlarge rigid impact is caused on the pipe body of the pill valve 4, particularly the inner wall of the turning part of the feeding end, on one hand, the pill valve 4 is easy to damage, the service life is shortened, on the other hand, the airtightness of the control part of the pill valve 4 is poor due to impact deformation, and a better flow control effect cannot be achieved.

In order to overcome the problem that the shot valve 4 in the conventional shot blasting structure body 1 is easily damaged or deformed, please refer to fig. 1 again, a settling chamber 14 is formed at one side of the bottom of the separation chamber 13 of the shot blasting structure body 1, which is far away from the shot blasting chamber 11, and the settling chamber 14 is arranged at one side of the shot blasting chamber 11 because the separation chamber 13 is partially protruded downwards, so that a first step is formed to play a primary buffering role of the shot, the effect of performing primary buffering and decelerating by the feeding end of the shot valve 4 is changed, not only is the structure of the feeding end of the shot valve 4 well protected, but also the measure for dealing with the deformation of the settling chamber 14 is easier to implement. Of course, the position of the settling chamber 14 at the bottom of the shot blasting chamber 11 is determined by gravity, generally speaking, the falling trajectory of the steel shot needs to be designed according to the gravity, and it is not excluded that the falling trajectory of the steel shot is changed due to too large external force such as setting an obstacle, and the settling chamber 14 at this time is designed according to the final falling foot point of the steel shot in the separation bin 13. The straight pipe type shot valve 4 is arranged between the side wall of the settling chamber 14 close to the shot blasting chamber 11 and the shot blasting chamber 11, and the straight pipe type shot valve 4 is adopted because the newly added design of the settling chamber 14 provides a space for direct connection of a straight pipe structure between the side wall of the settling chamber 14 and the shot blasting chamber 11 on one hand, and the design of a traditional bent pipe is replaced on the other hand, so that the phenomenon that the shot directly impacts the inner wall of a pipe body of the shot valve 4 can be avoided, the smoothness of flow or conveying of the shot in the shot valve 4 can be increased, the phenomenon of material blockage is not easy to occur, and the problem that the traditional bent pipe type shot valve 4 is easy to damage or deform is solved.

In order to further increase the flowability of the shots in the shot valves 4, the side wall of the settling chamber 14 close to the shot blasting chamber 11 is arranged along the inclined direction of the side wall of the shot blasting chamber 11 connected with the shot valves 4, namely, the side wall of the settling chamber 14 and the side wall of the shot blasting chamber 11 are designed in a manner of being inclined in the same direction, so that a direct connection space is reserved for the installation of the shot valves 4, wherein the side wall is not the bottom side wall of the settling chamber 14, but the side wall in the front-back direction during working, namely the side wall connected with the shot valves 4. Because the shot blasting chamber 11 is connected with the rebound bin 12 in a V shape, a certain inclination angle exists between the shot blasting chamber 11 and a vertical plane, namely the side wall of the shot blasting chamber 11 connected with the shot valve 4 has an inclination angle, preferably, the side wall of the settling chamber 14 connected with the shot valve 4 is parallel to the side wall of the shot blasting chamber 11, a space which is directly connected with the standard shot valve 4 can be directly reserved in the form, of course, in the actual installation process, the side wall of the settling chamber 14 connected with the shot valve 4 and the side wall of the shot blasting chamber 11 can be crossed to a certain degree, the purpose of directly connecting the shot valve 4 can be achieved, namely, an included angle exists between the plane where the side wall of the settling chamber 14 is close to the shot blasting chamber 11 and the plane where the side wall of the shot valve 4 connected with the shot blasting chamber 11 is located, the range of the included angle is generally smaller than 60 degrees, the cross form of the two planes is also shown, and the cross section, the angle between the two legs of the X is typically less than 60 degrees. The straight pipe type pill valve 4 after being installed can be ensured to directly connect, the higher flowing smoothness of pills is ensured, the pills impacted at high speed can enter the pill valve 4 after being buffered by the settling chamber 14, and the structure of the pill valve 4 is well protected.

Referring to fig. 3 and 4, the walking mechanism 2 includes a walking frame 21, a connecting sleeve 24 and a wheel frame 22 mounted with walking wheels 23, a vertical positioning shaft 25 is fixed on the upper surface of the wheel frame 22, the connecting sleeve 24 is movably sleeved on the positioning shaft 25, and one side of the connecting sleeve 24 is fixedly connected with the rebounding cabin 22 through a support plate, and the fixed connection mode can be welding, screwing, riveting or transition connection through an intermediate piece. A limiting part, which is a limiting cap, is arranged at one end of the positioning shaft 25, which is far away from the wheel carrier 22, a spring 28 sleeved on the positioning shaft 25 is arranged between the limiting part and the connecting sleeve 24, so that the connecting sleeve 24 is ensured to have a resetting effect, a supporting lever 26 is hinged to the upper surface of one side of the wheel carrier 22, which is far away from the bounce bin 22, through a hinged support, the number and the shape of the supporting lever 26 are selected according to the strength required to be supported, and a plurality of thicker supporting levers 26 can be arranged according to the required supporting strength; one end of the supporting lever 26 contacts with one end, namely the bottom end, of the connecting sleeve 24 far away from the spring to form a limit, and the other end of the supporting lever 26 is fixedly connected with the hand frame 31, and similarly, the fixed connection mode can be welding, screwing, riveting or transition connection through an intermediate piece. The handrail 31 can be a single rod as a main body support, or can be a form of two rods or even a plurality of rods as a main body support. By pressing the handrail 21 downwards, the connecting sleeve 24 can be pried upwards through the supporting lever 26, so that the part of the bounce bin 22 close to one side of the handrail mechanism 2 is tilted to achieve the purpose of climbing a ramp, and in addition, the purpose of pushing the whole machine to steer can be realized by rotating the handrail 21 leftwards and rightwards. Of course, a limit bolt may be provided on a portion of the connection sleeve 24 away from the positioning shaft 25 or on the support lever 26, and an end of the limit bolt may abut against an upper surface of the wheel frame 22, so as to adjust a limit position of the handrail frame 21 in the up-and-down rotation.
