Description

Technical Field

[0001] This invention relates to the field of material conveying technology, and in particular to a mechanical scraper-type arch-breaking feeding device. Background Technology

[0002] In the production and application of powdered materials, whether in the production process or in the granulation and packaging of finished products, the storage and conveying of bulk materials are important process links, which involve the application of intermediate buffer silos and discharge conveying equipment. Bulk materials are characterized by dust, flammability and explosiveness, and moisture absorption, which often makes them more prone to arching in the silo, thus affecting the material conveying. In order to ensure that the material is transferred to the next process stably and smoothly, it is necessary to select a reasonable arch-breaking and flow-aiding device. In order to control the accuracy of subsequent processes, it is necessary to measure the amount of material conveyed.

[0003] Existing arch-breaking feeding devices generally use rotary crushing to reduce material volume. However, when dealing with severe arching conditions, the simple rotary crushing action has limited effect on breaking the stable material arches that have already formed in the hopper. The material may still form voids around the crushing mechanism, resulting in poor material discharge. Furthermore, there is room for improvement in the coordination between the arch-breaking action and the feeding metering. When the arching is suddenly eliminated, the instantaneous increase in the amount of material falling can easily cause material accumulation in the feeding section, affecting the continuity and accuracy of subsequent metering. Summary of the Invention

[0029] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0030] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0031] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0032] Example 1, referring to Figure 1 and Figure 2 This is the first embodiment of the present invention. This embodiment provides a mechanical scraper arch-breaking feeding device, which includes a material dropping component 1, a feeding component 2 and a vibration component 3.

[0033] Specifically, it includes a material feeding assembly 1, which includes a fixedly installed transmission frame 11, a transmission cylinder 12 fixed on the transmission frame 11, a first motor 13 fixed on the transmission frame 11, a rotating rod 14 fixed on the output end of the first motor 13, and an arch-breaking component 15 installed on the rotating rod 14 for crushing materials inside the transmission cylinder 12.

[0034] The feeding assembly 2 is set on the transmission frame 11. The feeding assembly 2 includes a feeding cylinder 21 fixed on the transmission frame 11, a second motor 22 fixed to one end of the feeding cylinder 21, a feeding auger 23 fixed to the output end of the second motor 22, a third motor 24 fixed on the transmission frame 11, and a baffle plate 25 fixed to the output end of the third motor 24.

[0035] The vibration assembly 3 is mounted on the rotating rod 14. The vibration assembly 3 includes a torque limiter 31 mounted on one end of the rotating rod 14, a striking rod 32 mounted on the outside of the torque limiter 31, a striking head 321 fixed on one end of the striking rod 32, a positioning member 33 mounted on the striking rod 32 for positioning the center of rotation of the striking rod 32, and an elastic impact block 35 fixed inside the transmission cylinder 12.

[0036] like Figure 4 and Figure 7 As shown, a stabilizing frame 17 is fixed to the inner wall of the transmission cylinder 12. The top of the stabilizing frame 17 is designed with a pointed tip to avoid material residue. The rotating rod 14 is rotatably connected to the stabilizing frame 17 through a sealed bearing, thereby ensuring the stability of the rotating rod 14's rotation. The bottom of the auxiliary frame 36 is fixed to the stabilizing frame 17 to meet the stable rotation requirements of the auxiliary rod in the torque limiter 31.

[0037] Example 2, refer to Figures 2-9 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0038] Specifically, the arch-breaking component 15 includes a rotating block 151 fixed on the rotating rod 14, a guide groove 1511 is provided on the rotating block 151, a movable ring 152 is sleeved on the outside of the rotating block 151, a guide bead 1521 is provided on the inner ring of the movable ring 152, a first protruding rod 153 is fixed on the outer ring of the movable ring 152, a sliding groove 1532 is provided on one side of the first protruding rod 153, and an inclined groove 1533 is provided at the bottom of the inner cavity of the sliding groove 1532.

[0039] The arch-breaking component 15 also includes a displacement component 154 disposed on one side of the first protruding rod 153. The displacement component 154 includes a slider 1541 slidably connected in the slide groove 1532, a pressing block 1542 fixed to one end of the slider 1541, and a breaking rod 1543 fixed on the slider 1541.

[0040] The arch-breaking component 15 also includes a fixing block 155 fixed to the inner wall of the transmission cylinder 12, and the inner ring of the fixing block 155 is provided with an arc groove 1551.

[0041] When the pressing block 1542 rotates circumferentially following the first protruding rod 153, under the action of centrifugal force, the pressing block 1542 naturally extends outward. As the pressing block 1542 rotates circumferentially, it will contact the arc groove 1551, causing the pressing block 1542 to move inward. When the pressing block 1542 no longer contacts the fixed block 155, under the action of centrifugal force, the pressing block 1542 will extend outward again. This cycle continues. During the rotation of the first protruding rod 153, with the cooperation of the slider 1541 and the arc groove 1551, the crushing rod 1543 continuously extends and retracts, completing the crushing process of the material in the conveying cylinder 12.

[0042] like Figure 9 As shown, multiple fixed blocks 155 are distributed in a circumferential array inside the conveying cylinder 12, and the arc grooves 1551 on the fixed blocks 155 have different specifications. This design allows the arc grooves 1551 of different specifications to make the movement amplitude of the pressing block 1542 different when it rotates, and the corresponding crushing range also changes, thereby effectively crushing the material inside the conveying cylinder 12.

[0043] There are several guide beads 1521, all of which are installed on the top of the inner cavity of the movable ring 152, and the guide beads 1521 are fitted with the movable ring 152 with a clearance fit.

[0044] like Figure 5 As shown, the guide groove 1511 is a sinusoidal groove, which cooperates with the guide bead 1521. When the rotation speed of the rotating block 151 and the movable ring 152 are different, the guide bead 1521 moves relative to the guide groove 1511. With the cooperation of the guide bead 1521 and the guide groove 1511, the movable ring 152 will inevitably be driven to move up and down.

[0045] Specifically, the torque limiter 31 includes an active shaft sleeve 311 fixed on the rotating rod 14, a driven shaft sleeve 312 slidably engaged with the active shaft sleeve 311, an adjusting nut 313 disposed on one side of the driven shaft sleeve 312, and a Hall switch 3131 fixed on the adjusting nut 313. Correspondingly, a magnet is embedded in the driven shaft sleeve 312. As the driven shaft sleeve 312 moves, the Hall switch 3131 will output high and low level electrical signals.

[0046] It should be noted that if bridging occurs inside the conveying cylinder 12, the rotational torque of the rotating rod 14 increases, and the driving sleeve 311 and the driven sleeve 312 gradually separate. The Hall switch 3131 monitors the action of the driven sleeve 312 and outputs a signal to the controller. The controller automatically controls the third motor 24 to drive the baffle plate 25 to rotate. Correspondingly, when the bridging strength is high and the material accumulates and is difficult to fall properly, the higher the torque of the rotating rod 14, the greater the action distance of the driven sleeve 312, and the more the baffle plate 25 tends to be in a horizontal state, reducing the material falling space and thus maintaining the balance of the material entering the feeding cylinder 21. This avoids the situation where the material falling space is too large under bridging conditions, resulting in long blank sections without material in the feeding cylinder 21, making continuous conveying difficult and hindering subsequent material metering.

[0047] Specifically, the striking rod 32 has a horizontal groove 322, and a plurality of locking holes 323 are evenly distributed on the horizontal groove 322, such as... Figure 7 As shown, the vertical inner diameter of the locating hole 323 is larger than the vertical inner diameter of the transverse groove 322.

[0048] Specifically, the positioning component 33 includes a slide block 331 located on one side of the striking rod 32. The positioning rod 332 is fixed on the slide block 331, and one end of the positioning rod 332 is slidably connected to the locking hole 323. The locking bolt 333 is threadedly connected to the positioning rod 332, and the locking bolt 333 is in close contact with the striking rod 32. In this state, the positioning rod 332 can be locked and installed in the locking hole 323 by the locking bolt 333. The positioning rod 332 and the locking hole 323 cooperate to form the center of rotation of the striking rod 32. Since there are multiple locking holes 323, in actual use, the operator can flexibly adjust the position of the positioning component 33 on the striking rod 32 according to actual needs.

[0049] One end of the striking rod 32 is located above the driven bushing 312. When the driven bushing 312 is squeezed upward by the driving bushing 311, the driven bushing 312 will push the striking rod 32 to rotate around the positioning rod 332.

[0050] It should be understood that when the positioning rod 332 is closer to the driven bushing 312, under the premise that the driven bushing 312 moves up by the same distance, the action range of the striking rod 32 at the end away from the driven bushing 312, that is, the end where the striking head 321 is located, is greater, and the vibration generated by the striking head 321 and the elastic impact block 35 is stronger.

[0051] The vibration assembly 3 also includes a connecting bracket 34 disposed on the striking rod 32, the connecting bracket 34 being fixed to the auxiliary bracket 36, and as shown in the figure. Figure 8 As shown, the bottom of the connecting frame 34 is provided with a T-shaped groove for the slide block 331 to slide.

[0052] Specifically, a slot 111 is provided at the bottom of the transmission frame 11, and a baffle plate 25 is located inside the transmission frame 11. The inner cavity of the slot 111 communicates with the inner cavity of the feeding cylinder 21. The space formed by the feeding cylinder 21 and the slot 111 can meet the rotation space requirements of the baffle plate 25. Figure 3 As shown, when the baffle plate 25 is in a horizontal state, the overlapping area between the baffle plate 25 and the empty trough 111 is large, and the material in the transmission frame 11 can only slowly fall into the feeding cylinder 21 through the space between the baffle plate 25 and the empty trough 111. However, when the baffle plate 25 is in a vertical state, the overlapping area between the baffle plate 25 and the empty trough 111 is small, and the material in the transmission frame 11 can quickly fall into the feeding cylinder 21.

[0053] like Figure 3 As shown, a cleaning lever 16 is fixed on the outer ring of the rotating rod 14 and inside the transmission frame 11. The cleaning lever 16 rotates together with the rotating rod 14 and can be used to clean the material deposited at the bottom of the inner cavity of the transmission frame 11, so that the material can continue to be transported through the empty trough 111.

[0054] Example 3, referring to Figures 2-9 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0055] Specifically, the bottom of slider 1541 is slidably connected to inclined groove 1533, such as... Figure 6 As shown, a baffle is fixed laterally inside the groove 1532. The slider 1541 is restricted by the baffle and cannot detach from the first protrusion 153. The slider 1541 can only slide laterally inside the groove 1532 and the inclined groove 1533. When the slider 1541 slides, it will scrape off the residual material inside the groove 1532. Under the action of gravity, the residual material is drained and falls down through the inclined groove 1533.

[0056] A second protruding rod 1531 is fixed on one side of the first protruding rod 153 to assist in moving the material and improve the overall mixing and crushing effect.

[0057] The Hall switch 3131 and the striking rod 32 are designed to be offset, meaning that the rotation of the striking rod 32 will not make contact with the Hall switch 3131. Correspondingly, the induction between the Hall switch 3131 and the magnet will not be affected by the obstruction of the striking rod 32.

[0058] In practical applications, the device is equipped with a dustproof controller. The Hall switch 3131 outputs a signal to the controller, which then controls the third motor 24 to work and adjusts the tilt angle of the baffle plate 25.

[0059] like Figure 7As shown, the torque limiter 31 also includes an auxiliary rod rotatably connected to the auxiliary frame 36. The driven bushing 312 is slidably connected to the auxiliary rod, and the auxiliary rod is hexagonal in shape inside the driven bushing 312 to ensure the stability of the driven bushing 312's movement. When the driven bushing 312 rotates, the auxiliary rod rotates synchronously. A support spring is provided between the driven bushing 312 and the adjusting nut 313. The adjusting nut 313 is threadedly connected to the auxiliary rod, forming an adjustable design. The working principle of this part is all prior art, which can be clearly understood by those skilled in the art, and will not be described in detail here.

[0060] It should be noted that, in order to prevent the locking bolt 333 from loosening due to the rotation of the striking rod 32, an anti-loosening nylon insert is added to the locking bolt 333 and thread-locking agent is applied.

[0061] like Figure 7 As shown, a counterweight is fixed to the top of the striking rod 32 and near the driven bushing 312. When the driven bushing 312 moves down to reset, the tilted striking rod 32 will automatically rotate and reset under the action of the counterweight.

[0062] In practical applications, the driven bushing 312 and the driving bushing 311 are fitted with elastic dust covers to prevent powder materials from affecting the normal transmission of the driven bushing 312 and the driving bushing 311.

[0063] In practical applications, the striking head 321 includes a hollow housing, a disc spring assembly fixed inside the housing, and an inertial impact block. Inside the hollow housing, the front end is a freely sliding inertial block, and the rear end is supported by a set of replaceable disc springs. With this design, when the striking head 321 strikes the elastic impact block 35, the outer housing strikes the elastic impact block 35. At this time, the impact force is gentle and mainly plays a stabilizing role, protecting the elastic impact block 35. At the moment of impact, the striking head 321 decelerates as a whole, but the inertial impact block inside will compress the disc spring forward under the action of inertia and violently strike the inner wall of the outer punch. The real and powerful destruction of the material vibration is generated by this subsequent internal impact that acts directly between metals.

[0064] In practical applications, the elastic impact block 35 is designed to be detachable, requiring staff to regularly inspect or replace it according to the usage time of the device.

[0065] In use, the first motor 13 drives the rotating rod 14 to rotate the arch-breaking component 15 inside the transmission cylinder 12. Under normal working conditions, when the rotating block 151 rotates, the pressing block 1542 reciprocates with the arc groove 1551 on the fixed block 155 under the action of centrifugal force, causing the crushing rod 1543 to extend and retract to crush. At the same time, the guide bead 1521 moves along the guide groove 1511, driving the entire movable ring 152 and the first protruding rod 153 to move up and down to expand the crushing range, so that the material falls smoothly and enters the feeding cylinder 21 through the space between the baffle plate 25 and the empty trough 111, and is conveyed by the feeding auger 23.

[0066] When arching occurs inside the conveying cylinder 12, the increased material resistance causes the torque of the rotating rod 14 to rise. The driven bushing 312 in the torque limiter 31 overcomes the spring force and undergoes axial displacement. This action, on the one hand, pushes the striking rod 32 to rotate around the positioning member 33, causing the striking head 321 to strike the elastic bearing block 35, generating vibration to assist in breaking the arch. On the other hand, the displacement action is sensed by the Hall switch 3131 and transmits a signal to the controller. The controller controls the third motor 24 to drive the baffle plate 25 to rotate horizontally, reducing the material drop space, thereby preventing a large amount of material from rushing into the feeding cylinder 21 at the moment the arch is eliminated, maintaining the continuity and uniformity of feeding, and ensuring the accuracy of subsequent metering processes.

[0067] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
