[0040] Example 1

[0041] Reference Figure 1-4 The present invention discloses a safe and durable crawler shot blasting machine, including a shot blasting assembly 100. In this embodiment, the shot blasting assembly 100 includes a shot blasting box 101, a shot blasting component 102 arranged in the shot blasting box 101, and a feeding component 103 arranged at the lower end of the shot blasting box 101. The shot blasting component 102 is the main structural component of the shot blasting. A feeding component 300 is arranged at one end of the shot blasting box 101, and the feeding component 300 is used to transport the shot material, and then after shot blasting, the shot pieces are sent out by using the feeding component 103.

[0042] Furthermore, the present invention also includes a protection component 200 . In this embodiment, the protection component 200 includes a protection door member 201 disposed near the feeding member 300 and a locking member disposed on the protection door member 201 .

[0043] In this embodiment, the locking component includes a safety pin arranged on the protective door 201 and a socket arranged on the shot blasting box 101 and cooperating with the safety pin to prevent accidental falling and improve safety.

[0044] In this embodiment, the shot blasting component 102 includes a first shot blasting roller 102a, a second shot blasting roller 102b and a third shot blasting roller 102c arranged in the shot blasting box 101.

[0045] Preferably, when observed from the side direction of the shot blasting box 101, the first shot blasting roller 102a is arranged away from the open end of the shot blasting box 101, and is arranged horizontally as a whole and is located at the lowest position, while the second shot blasting roller 102b is relatively high, and the third shot blasting roller 102c is arranged at the highest point, and the lateral position is located in the middle direction of the first shot blasting roller 102a and the second shot blasting roller 102b, and in order to achieve the best tensioning effect on the crawler and the highest shot blasting effect, the ratio of the longitudinal spacing between the second shot blasting roller 102b and the first shot blasting roller 102a to the longitudinal spacing between the second shot blasting roller 102b and the third shot blasting roller 102c is 1:2-1:3, and in the present embodiment, it is preferably 1:2.2.

[0046] For further reference, Fig.13 A dust removal component 104 is directly connected to the shot blasting box 101. The dust removal component 104 includes a dust removal box 104a arranged on the shot blasting box 101 and an air inlet pipe 104b connecting the shot blasting box 101 and the dust removal box 104a. A guide plate 104c is arranged inside the dust removal box 104a. Two guide plates 104c are arranged, and a certain angle is formed between the two guide plates 104c. The angle between the two guide plates 104c is between 110° and 120°.

[0047] Furthermore, the first shot blasting roller 102a, the second shot blasting roller 102b and the third shot blasting roller 102c are covered with a shot blasting track 202, and a plurality of shot blasting holes are opened on the shot blasting track 202. The shot blasting track 202 is taut in a section between the first shot blasting roller 102a and the third shot blasting roller 102c, and is also taut in a section between the first shot blasting roller 102a and the second shot blasting roller 102b, while being relatively relaxed in a section between the second shot blasting roller 102b and the third shot blasting roller 102c.

[0048] A guide ring 203 is arranged on the inner wall of the shot blasting box 101, and the shot blasting track 202 is in contact with the side of the guide ring 203 after passing through the second shot blasting roller 102b and the third shot blasting roller 102c. An auxiliary baffle 204 is arranged at the lower end of the guide ring 203 in the shot blasting box 101, so that the shot blasting track 202 is bent after passing through the second shot blasting roller 102b and the third shot blasting roller 102c, thereby forming a semi-enclosed concave structure when viewed from the side.

[0049] refer to Figure 10-12 As a preferred embodiment, a deformable member 207 is provided on the side wall of the shot blasting box 101, and the deformable member 207 includes a clamping ring 207a connected to the wire ring, and the clamping ring 207a is fixedly connected to the side wall of the shot blasting box 101. A plurality of splicing plates 207b are arrayed on the clamping ring 207a, and a sliding bar 207c is provided at the lower end of each splicing plate 207b. In order to achieve sliding, a plurality of sliding grooves cooperating with the sliding bar 207c are provided on the upper surface of the clamping ring 207a. The control plate 207d is rotatably connected to the part, which is not connected to the rotating shaft and has a control rod extending outward, which can be operated by an operator to rotate. A plurality of first protrusions 207e are arranged on the side wall of the control plate 207d, and a second protrusion 207f is arranged at the rear end of each sliding bar 207c. The sliding bar 207c is matched with the sliding groove, and a friction pad is arranged on the side wall of the sliding bar 207c to increase the friction between the sliding bar 207c and the sliding groove.

[0050] Furthermore, an extension guide rod 207g is eccentrically connected to the control disk 207d. Two extension guide rods 207g are provided, one of which is hinged to the second shot blasting roller 102b, and the other is hinged to the third shot blasting roller 102c. After the control disk 207d rotates, it will pull the second shot blasting roller 102b and the third shot blasting roller 102c to move.

[0051] In order to move, a slot for the second shot blasting roller 102b and the third shot blasting roller 102c to move is opened on the shot blasting box 101, and in order to achieve sealing, a baffle 207h is provided on the second shot blasting roller 102b and the third shot blasting roller 102c, which can always seal the slot during movement, and in order to lock the second shot blasting roller 102b and the third shot blasting roller 102c, a detachable connecting flange 207j is provided on the second shot blasting roller 102b and the third shot blasting roller 102c, and the connecting flange 207j is connected to the shot blasting box 101 by bolts.

[0052] Then, the operator can first loosen the connecting flange 207j, and then use the control lever to drive the rotation of the control disk 207d. The control disk 207d rotates so that the first protrusion 207e touches the second protrusion 207f, and then pushes the sliding bar 207c outward. The outward movement of the sliding bar 207c causes the shot blasting track 202 passing through a section of the guide disc to deform, thereby increasing the curvature of this part and pushing the entire shot blasting track 202 toward the first shot blasting roller 102a for a distance. At this time, the second shot blasting roller 102b and the third shot blasting roller 102c will move synchronously with it (the track tension and length are constant). After adjusting to the appropriate position, the operator uses bolts to connect the connecting flange 207j to the shot blasting box 101 to lock the second shot blasting roller 102b and the third shot blasting roller 102c.

[0053] The above-mentioned setting can further adjust the curvature of the middle section of the shot blasting track 202, and further adjust the concave part of the entire shot blasting track 202, thereby increasing the relative space for shot blasting and being able to accommodate more parts. At the same time, this setting can arbitrarily adjust the curvature of the shot blasting track 202, thereby making the shot blasting track 202 affect the effect of shot blasting and increase or decrease the shot blasting time.

[0054] Furthermore, in this embodiment, the unloading component 103 includes an unloading opening 103a opened at the lower end of the shot blasting box 101, and the unloading opening 103a is arranged directly below the shot blasting box 101, so that the shot can fall vertically downward through the shot blasting hole after shot blasting, and a unloading plate 103b is arranged at the lower end of the unloading opening 103a, and the unloading plate 103b is arranged horizontally, and the unloading plate 103b can be pulled out horizontally, so as to facilitate the operator to unload the shot.

The feed screen plate 103c is arranged on the upper surface of the feed plate 103b, and can screen the pills to screen out pills of different diameters. A screening bar 103d is arranged on the feed plate 103b, and the lower end of the screening bar 103d is in contact with the surface of the feed screen plate 103c, and the lower end of the screening bar 103d is split into a plurality of split strips, leaving gaps between the split strips.

[0055] A plurality of sieving holes 400 are provided on the surface of the unloading sieve plate 103c, and an auxiliary sieve plate 401 is slidably connected to the lower end of the unloading sieve plate 103c. The auxiliary sieve plate 401 is provided with auxiliary sieve holes 402 corresponding to the sieving holes 400, and the size ratio of the auxiliary sieve holes 402 to the sieving holes 400 is 1:1.2-1:1.3, so that the unloading sieve plate 103c can be used to sieve pills of different diameters. At the same time, because the auxiliary sieve holes 402 are provided on the auxiliary sieve plate 401, and the sieve holes on the unloading sieve plate 103c are larger than the auxiliary sieve holes 402, large and small particles of pills can be separated, and smaller-sized pills will directly fall to the ground. The operator can choose to receive the waste frame at the bottom to receive pills that do not meet the size.

[0056] An electric control cylinder is provided between the blanking plate 103b and the blanking screen plate 103c for controlling the distance between the blanking plate 103b and the blanking screen plate 103c.

[0057] Preferably, in the present embodiment, the protective door member 201 includes a protective door 201a arranged on the shot blasting box 101 and a traction member 201b arranged on the protective door 201a. The protective door 201a can close the side wall of the shot blasting box 101. In the present embodiment, the traction member 201b includes a cylinder hingedly arranged on the shot blasting box 101. Two cylinders are arranged, one of which is arranged at the top and the other is arranged at the lower position of the shot blasting box 101, and the two cylinders are respectively hinged to the protective door 201a, so that the protective door 201a, the two cylinders and the side wall of the shot blasting box 101 form a parallelogram, and when the cylinder is pushed, the protective door 201a can be driven to move.

[0058] A plurality of sealing rods 205 are arranged on the inner side of the protective door 201a near the shot blasting box 101, and the plurality of sealing rods 205 are arranged equidistantly. A sealing stop rod 206 is arranged on the shot blasting box 101, and the sealing stop rod 206 cooperates with the sealing rod 205 to form a seal to enhance the sealing effect.

[0059] Furthermore, the feed component 300 includes a feed base plate 301 connected to the shot blasting box 101, a feed plate 302 arranged on the feed base plate 301, and a protective net 303 arranged on the feed base plate 301, the protective net 303 is arranged on both sides of the feed plate 302, the end side of the feed plate 302 is hinged to the feed base plate 301, and a hydraulic cylinder 304 connected to the feed plate 302 is arranged on the feed base plate 301.

[0060] Operation process: During the shot blasting operation, the shot material for shot blasting enters the shot blasting box 101 using the feeding component 300 at the upper end, and then the first shot blasting roller 102a, the second shot blasting roller 102b and the third shot blasting roller 103c rotate, and the shot material is shot blasted using the shot blasting crawler 202. During shot blasting, the shot blasting crawler 202 runs forward, and the workpiece is continuously tumbling, and the shot is projected at high speed onto the tumbling workpiece surface, so that the workpiece can be completely and evenly cleaned, and the steel shot flows downward through the chute on the shot blasting crawler 202 onto the lower unloading plate 103b, and then the steel shot is transported to the bucket elevator, and then lifted to the separator by the bucket elevator, and stored for standby use after being separated. After the shot blasting is completed, the shot blasting room door automatically opens, the crawler reverses, and the workpiece is unloaded.

The rotation plane of the swing rod 701 is horizontally arranged, so that it can move away from or close to the first connecting rod 505a after rotation. A grabbing member 702 is also rotatably connected to the end of the swing rod 701, and a gear 703 is also provided at the rear end of the grabbing member 702. There are two grabbing members 702, so that there are also two gears 703. A rack 704 is slidably connected in the swing rod 701, and the rack 704 is meshed with the two gears 703. When the rack 704 slides, it will drive the two gears 703 to rotate, so that the two grabbing members 702 rotate accordingly, thereby realizing the grabbing and releasing actions.

[0065] Furthermore, the front end of the grabbing member 702 is connected to both ends of the spring 603a, and a driving gear 705 meshing with the rack 704 is rotatably connected inside the swinging rod 701, and a rotating member 800 is arranged between the driving gear 705 and the first connecting rod 505a. In the present embodiment, the rotating member 800 includes a first rotating rod 801 connected to the driving gear 705, a second rotating rod 802 connected to the rotating shafts of the first connecting rod 505a and the second connecting rod 505b, and a transfer member arranged between the first rotating rod 801 and the second rotating rod 802, and a micro motor is arranged on the driving gear 705 for rotating the driving gear 705.

[0066] Among them, in this embodiment, the transfer member includes a plurality of first transfer rods 803 connected to the first rotating rod 801 and a second transfer rod 804 connected to the second rotating rod 802. Hemispherical blocks are arranged at the ends of the first rotating rod 801 and the second rotating rod 802, and the first transfer rod 803 is arranged along the spherical surface, and the second transfer rod 804 is also arranged along the spherical surface. The plurality of first transfer rods 803 and the second transfer rods 804 are arranged in an alternating manner.

[0067] The rest of the structure is the same as that of Example 1.

[0068] Operation process: When the pills are discharged, they will fall through the sieve holes. There are two operating methods when they fall. The operator can make the pills fall naturally without changing the distance between the discharge plate 103b and the discharge screen plate 103c, and collect the pills after classification. The other method is to make the distance between the discharge plate 103b and the discharge screen plate 103c closer. As the discharge plate 103b and the discharge screen plate 103c approach each other, the first connecting rod 505a and the second connecting rod 505b approach each other, thereby driving the clamping plate 506 to move closer to the center position, so that the falling pills can be temporarily grabbed, because after the clamping plates 506 move closer to each other, the distance between them will buffer and slow down the discharge of the pills.

[0069] Then, the proximity of the clamping plate 506 can be adjusted according to different shot materials, by driving the swing rod 701 to approach the first connecting rod 505a and the second connecting rod 505b, and by allowing the grabbing piece 702 on the swing rod 701 to grab the two ends of the spring 603a, and then by driving the rotation of the gear 705, the rack 704 is driven to slide, and then the gear 703 is driven to rotate, thereby driving the grabbing piece 702 to rotate. Because the two ends of the grabbing piece 702 are connected to the two ends of the spring 603a, the two grabbing pieces 702 can be driven to rotate, and the two ends of the spring 603a can be pulled closer or farther, thereby adjusting the distance between the unloading screen plate 103c and the auxiliary screen plate 402.

[0070] There is also a configuration in which the grabbing member 702 is not connected to both ends of the spring 603a, so that the spring 603a is in a free state, and the pellets are not controlled when they fall.
