Examples

Referring to fig. 1 to 3, the steel plate type shot blasting machine provided in this embodiment includes a shot blasting machine body with a separation bin 3, the shot blasting machine body in this embodiment mainly includes a bounce bin 1, a shot blasting chamber 2 and the separation bin 3, a shot blasting head is installed in the shot blasting chamber 2, a shot blasting motor 4 connected directly is disposed on an outer wall of the shot blasting chamber 2 for driving the shot blasting head to rotate at a high speed to achieve a purpose of impacting a surface to be processed with a shot at a high speed, the shot after impact rebounds to the separation bin 3 through the bounce bin 1, and the shot and impurities fully pass through the separation bin 3, and then the shot enters the shot blasting chamber 2 again to perform circular impact. In order to facilitate the driving of the shot blasting machine body to move forward, a hand support 5 is generally fixed on the outer wall of the shot blasting chamber or the outer wall of the separation bin, so that an operator can conveniently control the shot blasting machine body by hands. The hand support 5 of this embodiment possesses detachability, specifically, it includes main support 51 and the assistant support 52 that roughly is the U type, main support and shot-blasting chamber 2's outer wall fixed connection, fixed connection's mode can be welding, the spiro union, the riveting, lock joint or joint etc., can dismantle between assistant support 52 and the main support 51 and be connected, the mode that can dismantle the connection can be the spiro union, the lock joint, activity joint or activity are pegged graft etc., not only can realize the certain distance under swing joint's prerequisite and adjust the purpose, and can guarantee that hand support 5 possesses higher detachability.

In addition, in order to reduce the difficulty of driving the shot blasting machine body to travel, the traveling mechanisms 7 are arranged on the shells of the rebounding bin 1 and/or the shot blasting chamber 2 of the shot blasting machine body, namely, at least one of the rebounding bin 1 and the shot blasting chamber 2, namely, the traveling mechanisms 7 are arranged on the outer wall, of course, the number of the traveling mechanisms 7 can be multiple, and the traveling mechanisms are specifically selected according to the occupied area and the design form of the shot blasting machine body and only need to be capable of supporting the shot blasting machine body to normally travel. In the embodiment, the two sides of the outer wall of the shot blasting chamber 2 are provided with the traveling mechanisms 7, and the single group of traveling mechanisms 7 is taken as an example for explanation, where the traveling mechanism 7 includes a casing 71 and a traveling wheel 72 rotatably mounted on the casing 71, a driving assembly for driving the traveling wheel 72 to travel is mounted on the casing 71, and when the driving assembly is in a starting state, the traveling wheel 72 can be driven to travel autonomously, that is, the driving assembly can drive the traveling wheel 72 to rotate in this state; when the drive assembly is in the off condition, the road wheels 72 are free to roll, meaning that the drive assembly is relatively free to the road wheels 72 in this condition, and the road wheels 72 are free to roll relative to the ground. Of course, the off state does not necessarily mean that the driving assembly is in an unpowered state or an inactive state, but may also mean that the driving assembly and the road wheels 72 are in a separated state, which is similar to the clutch function of a clutch.

The driving assembly may be in the form of an independent driving motor, or in the form of a driving motor cooperating with a transmission mechanism, and the latter is adopted in this embodiment, specifically, the driving assembly includes a walking motor 73 and a sprocket transmission mechanism 74, a speed reducer is provided between an output end of the walking motor 73 and a driving wheel of the sprocket transmission mechanism 74, so that the walking wheel 72 can reach a rotation state through the speed change of the speed reducer under the condition that the walking motor 73 is started, thereby realizing the walking function of the walking wheel 72, and of course, the sprocket transmission mechanism 74 may also be replaced by a belt pulley or a multi-stage gear transmission mechanism. A driven wheel of the chain wheel transmission mechanism 74 is provided with a gear engaging disc, the gear engaging disc and the driven wheel are coaxial and are in rotatable fit through a bearing, the gear engaging disc is fixedly connected with a wheel shaft of the walking wheel 72, and the gear engaging disc is provided with an upper gear bolt 75 which can mutually fix the gear engaging disc and the driven wheel, when the upper gear bolt 75 is taken down, the gear engaging disc and the driven wheel can relatively rotate, at the moment, the driving assembly and the walking wheel 72 are in a separated state, and the walking wheel 72 can freely rotate no matter whether the walking motor 73 is started or not; when the upper gear bolt 75 is inserted, the gear engaging disc and the driven wheel can be fixed with each other, the driving assembly and the walking wheel 72 are in a closed state at the moment, and the walking motor 73 is started to drive the walking wheel 72 to rotate autonomously.

An electric cabinet 6 is integrated on the hand-held support 5, the electric cabinet 6 is mainly used for realizing the respective or integral control of the shot blasting motor 4 and the walking motor 73, and the design position of the electric cabinet 6 is very convenient for an operator to operate. In addition, considering that the traveling mechanism 7 is mainly disposed at the shot blasting chamber 2, which is likely to cause gravity center shift and affect the sealing performance of shot impact, the counterweight 8 is disposed on the rebounding bin 1 of the shot blasting machine body and/or the housing of the shot blasting chamber 2, that is, the counterweight 8 is mainly hung on at least one of the rebounding bin 1 and the shot blasting chamber 2, and is mainly used for keeping the gravity center of the shot blasting machine body balanced, preferably, the counterweight 8 and the traveling mechanism 7 are respectively disposed on the rebounding bin 1 and the shot blasting chamber 2, so that the weights of the shot blasting machine body on both sides of the impact port are relatively balanced, and the gravity center approaches the impact port more.

Because the pill material flow enters the separation bin 3 from the rebound bin 1, especially at the connecting port of the rebound bin 1 and the separation bin 3, if the pill material flow is not sufficiently decelerated and separated, certain impact damage can be caused, the pill material is not completely separated, and the loss rate is high. In order to overcome the above problems, please refer to fig. 4 to 7, a separation settling bin 33 is disposed in the separation bin 3, the separation settling bin 33 has a feeding port 333 communicated with the exit port 11 of the rebound bin, the separation settling bin 33 has a discharge port 334 communicated with the inner cavity of the separation bin 3, a corresponding flow guiding trajectory, i.e., the inner cavity wall of the separation settling bin 33, is disposed between the feeding port 333 and the discharge port 334, the pellet flow exiting from the rebound bin 1 directly enters the separation settling bin 33, and after the guiding and decelerating actions of the corresponding trajectory, sufficient deceleration and buffering effects are achieved, the impact of the pellet flow entering the inner cavity of the separation bin 3 can be reduced, and the long service life of the corresponding structure in the separation bin 3 is ensured. In addition, the pellet flow enters the separation bin 3 by the rebound impact force of the surface to be treated and depends on external suction force, namely, a dust removal pipe connecting port 10 is formed in the separation bin 3 and is used for being connected with a dust removal pipe, one end, far away from the separation bin 3, of the dust removal pipe is connected with a negative pressure suction pump, negative pressure suction can be carried out on the separation bin 3 through the dust removal pipe, and therefore the pellet flow can fully enter the separation bin 3. Certainly, in order to ensure that the negative pressure suction effect is not too large, that is, the pellet which does not fully impact the surface to be treated is directly sucked, so that the surface treatment effect is reduced, a plurality of air holes 32 are processed on at least one side wall of the separation bin 3, a rotatable air inducing cover 31 is arranged on the side wall which is processed with the air holes 32, the air inducing cover 31 can be fixedly connected or hinged with the separation bin 3, external air can enter the separation bin 3 through the air inducing cover 31 and the air holes 32, the negative pressure suction effect is balanced and relaxed to a certain extent, and an air gap between the air inducing cover 31 and the separation bin 3 can be adjusted, so that whether the negative pressure suction effect needs to be balanced to a required degree or not is selected according to different working conditions.

Considering that the negative pressure suction effect at the dust removal pipe is too strong, which causes the shot loss rate to be higher (sucked into a rear dust removal system), like the shot blasting machine with the application number of 201921345558.8, the steel shot loss rate is too large, which causes the increase of the construction cost, the upper part of the separation bin 3 is provided with a secondary sedimentation bin 9, the dust removal pipe connector 10 is arranged on the secondary sedimentation bin 9, the secondary sedimentation bin 9 is used as a further buffer space, which can effectively increase the stroke of the shot entering the dust removal pipe, and the phenomenon of being sucked away by the dust removal pipe can not easily occur, in addition, a secondary separation sedimentation component can be arranged in the secondary sedimentation bin 9, so that a large amount of impurities and a small amount or trace amount of shot can be further separated and sedimentated. Certainly, the secondary separation and sedimentation component can adopt a form of a separation and sedimentation bin 33, and also can be in a baffle plate form with adjustable telescopic length, and only needs to play a certain role in blocking a large amount of impurities or a small amount of pills. It should be noted that, the main separation function of the pellet and the impurities is realized by the separation settling bin 33, in order to achieve the sufficient separation effect of the pellet and the impurities, the separation settling bin 33 is provided with a separation material port, and the separation material port is provided with an openable material door 34, that is, the material door 34 is in a movable opening state, and can be opened under the suction function of the separation bin 3 (the suction force of the dust removal pipe), and is opened to a certain extent, so that the light impurities are easily sucked away by the negative pressure function, and finally, the sufficient separation effect between the pellet and the impurities is achieved. Through the design of the above separation settling bin 33, especially the design of the material door 34, the separation effect of the pellets and the impurities is increased, not only is additional configuration of suction equipment such as a fan not needed, but also the impurity pumping effect can be easily realized only by the suction force of the dust removal pipe, and after the trajectory of the pellet flow (pellets and impurities) between the feeding port 333 and the discharge port 334 is fully decelerated, the impact force is reduced, and the suction separation of the pellets and the impurities is more facilitated.

In order to further increase the separation effect of the pellet material flow between the feeding port 333 and the discharging port 334, the separation port is located on the separation settling bin 33 at the side of the discharging port 334 close to the dust removal pipe connecting port 10, and can be closer to the dust removal pipe connecting port 10 relative to the discharging port 334, so that the impurities can be preferentially discharged from the separation port, and the rest of the pellet material is ejected from the discharging port 334, so that the further separation effect of the pellet material and the impurities can be achieved. In addition, one side of the material door 34 close to the dust removal pipe connecting port 10 is hinged to the separation settling bin 33, the other side of the material door can rotate towards one side close to or far away from the dust removal pipe connecting port 10, namely the upper side of the material door 34 is hinged to the separation settling bin 33 through a hinge or other hinges, the lower side of the material door is in a free opening and closing state, the pellet flow can firstly impact on the material door 34 and then enter the separation bin 33, the possibility that the pellet flow is directly sucked due to the fact that the dust removal pipe has an overlarge suction effect is avoided, and the loss rate of the pellet is reduced. Of course, the bin gate 34 is made of wear-resistant and impact-resistant metal, and the hinged part of the bin gate is detachably hinged by a metal pin, so that the detachability and the use reliability of the bin gate 34 can be fully ensured.

In this embodiment, the separation and sedimentation bin 33 comprises a top plate 331 and a bottom plate 332, a feeding port 333 is formed between the top plate 331 and one end of the bottom plate 332, a discharging port 334 is formed between the other end of the top plate 331 and the other end of the bottom plate 332, and the separation port is opened on the top plate 331, which is designed as a preferred structure form of the separation and sedimentation bin 33, and is simple, easy to manufacture, durable and reliable. Of course, the side plate of the separation settling bin 33 may be the side wall of the separation bin 33, or may be a metal plate fixed between the top plate 331 and the bottom plate 332, and it is only necessary to ensure the sealing performance of the portions of the separation settling bin 33 outside the feeding port 333 and the discharging port 334, and the pellet stream can only enter from the feeding port 333 and be ejected from the discharging port 334.

In order to make the top plate 331 and the bottom plate 332, especially the top plate 331, perform sufficient deceleration on the pellets, the top plate 331 includes a tangential deceleration section 3311, a curved deceleration section 3312 and a ramp deceleration section 3313 connected in sequence, a side surface, i.e. a lower surface, of the tangential deceleration section 3311 close to the bottom plate 332 is an inclined surface, and the inclined surface is inclined along the exit direction of the rebounded bin 1, i.e. the inclined surface is linked tangentially. The surface of one side, namely the lower surface, of the curved arc deceleration section 3312 close to the bottom plate 332 is a curved arc surface, and the center of the curved arc is positioned at one side, namely the lower side, of the curved arc surface close to the bottom plate 332, so that the main deceleration function can be realized on the pill flow through the curved arc function. The surface of the inclined block deceleration section 3313 close to the bottom plate 332, i.e. the lower surface, is an inclined surface, and one end, i.e. the upper end, of the inclined surface close to the tangential deceleration section 3312 is inclined towards one side of the ejection port 11 of the bounce-back bin, so that the ejection direction of the discharge port 334 is inclined downwards, especially the ejection direction of the ejection port 11 of the bounce-back bin is inclined downwards, and the inclined surface can be aligned to the position of the pill valve as much as possible, thereby ensuring the smooth circulation and recovery of pills. In addition, the cambered surface with the inclined plane with adopt smooth transition's mode between the junction on inclined plane, can be guaranteeing under the prerequisite of better buffering effect, slow down the impact damage between pill material stream and roof 331, of course, in other embodiments, under the better prerequisite of roof 331 material, the cambered surface with the inclined plane with also can adopt the step transition between the junction on inclined plane, can play better more abundant buffering effect. After the pellet flow is buffered by the lower surfaces of the three, the impact speed of the pellet flow can be greatly reduced, and the subsequent separation effect of the pellet and the impurities is more facilitated.

The sorting port is located on the inclined-blocking speed reduction section 3313, namely, the sorting port is located on the end section of the pill flow speed reduction, at the moment, impurities are separated from the pills, the separation effect is optimal, particularly, light impurities can be ejected through the gap between the material door 34 and the inclined-blocking speed reduction section 3313, most of the impurities are located above the pills, and can be taken away by the negative pressure suction effect of the dust removal pipe more quickly and directly, so that the effect of full separation is realized. In addition, because part of the impurities cannot be sucked away by the negative pressure action once, in order to achieve the purpose that the impurities are sufficiently sucked, the top plate 331 further comprises a bending deceleration section 3314 with a plurality of sieve holes, one end of the bending deceleration section 3314 is connected with the inclined blocking deceleration section 3313 to form an included angle, the included angle is smaller than 60 degrees, the other end of the bending deceleration section 3314 can incline towards one side of the bent arc deceleration section 3312, a short stopping platform can be provided for the pill flow entering the bending deceleration section 3314 and between the inclined blocking deceleration sections 3313, the sieve holes of the bending deceleration section 3314 are mainly circular holes, the shape of the steel pill can be adapted to the shape of the steel pill, the impurity particles with different shapes cannot easily pass through the sieve holes and stop on the bending deceleration section 3314, and the separation of the negative pressure suction action is waited to continue. In addition, a material leakage port 335 is formed in one side of the bottom plate 332, which is close to the exit port 11 of the rebound bin, so that a channel for some pills with large mass and small kinetic energy to directly enter the separation bin 33 can be provided, the pills can directly reach a pill valve without being ejected from the discharge port 334, and the pressure for separating the pills from impurities at the discharge port 334 is reduced.

Through the design of the sorting and settling bin 33, the characteristics that the impurity quality is light and is greatly influenced by the negative pressure effect are fully utilized, and the ball material with relatively large quality are fully decelerated in advance under the combined action of the space separation position and the corresponding separation design, and the ball material and the impurity after being decelerated can be fully separated.
