Description

Technical Field

[0001] The invention relates to the technical field of brick-making material distribution, in particular to a material distribution trolley. Background Art

[0002] At present, brick making equipment generally includes a feeding mechanism, a material distribution machine, a brick making machine, a brick transmission mechanism, a stacking mechanism, etc. The material distribution machine includes a hopper and a material distribution vehicle. The hopper is filled with brick base materials. The material distribution vehicle delivers materials back and forth between the hopper and the brick making machine. After the material distribution vehicle receives the base materials under the hopper, it delivers the base materials to the mold cavity of the brick making machine and returns after the material distribution is completed. Then the brick making machine operates to form blocks.

[0003] The most critical technical problem in the material distribution process of the material distribution vehicle is uniform material distribution. Specifically, when the material distribution vehicle distributes materials into the rear mold cavity, the base material falling into the mold cavity will always have partial material accumulation (material accumulation at the back and lack of material at the front), or even material shortage in the dead corner. If it is not improved, it will greatly affect the quality of subsequent block forming. Therefore, uniform material distribution is one of the most critical technologies in brick making.

[0004] In the prior art, various improved designs of material distribution vehicles have been proposed to address the above problems. They are all based on a common design idea, that is, various material leveling and rake mechanisms are arranged in the vehicle cavity of the material distribution vehicle, and various actions such as material leveling and rake are performed by the material leveling and rake to solve the problem of uneven material distribution. The material leveling and rake mechanism is usually provided with a plurality of rake units arranged side by side. Since each rake unit can only perform rake and rake actions back and forth within a specific small range of its own design, the action form is limited, and there is a problem of incompatibility with the pile phenomenon, and the efficiency and effect of material leveling are not very ideal. Summary of the invention

[0005] The object of the present invention is to provide a material distributing trolley which innovatively adopts a method of adjusting the opening of a material discharging port by means of a draw plate to achieve uniform material distributing, thereby achieving a uniform material distributing effect with high efficiency and high uniformity.

[0006] In order to achieve the above object, the solution of the present invention is:

[0007] A material distribution trolley comprises a trolley body, a drawer plate and a drawer plate driving unit; the trolley body has a material cavity, the bottom of which is hollowed out to form a material discharge port; the drawer plate is movably mounted on the trolley body, and the drawer plate is driven by the drawer plate driving unit to perform a pulling action to adjust the opening of the material discharge port; the two limit states of the material discharge port opening adjustment are a fully closed state and a fully open state of the material discharge port.

[0008] The material distributing trolley also includes a vibrator, which is installed on the trolley body at a position corresponding to the position close to the material cavity.

[0009] The fabric trolley further includes a drawplate guiding mechanism, which has two sets provided on both sides of the drawplate. The drawplate guiding mechanism includes a guide rod, a guide sleeve and a connecting side plate; the guide rod is provided on the trolley body, the guide sleeve is movably sleeved on the guide rod, and the guide sleeve is integrally connected with the drawplate through the connecting side plate.

[0010] The fabric trolley also is provided with a drawplate sensing mechanism, which includes a first sensor and a second sensor, and the first sensor and the second sensor respectively sense and detect the two limit states.

[0011] A material cavity adjusting plate is provided in the fabric trolley. The material cavity adjusting plate serves as the cavity wall of the material cavity to adjust the capacity of the material cavity; the lower end of the material cavity adjusting plate extends to the discharge port to serve as the edge of the discharge port to adjust the size of the discharge port.

[0012] The material cavity adjusting plate is connected with an adjusting plate mechanism, which includes a strip-shaped groove locking part and a pressing part; the material cavity adjusting plate is adjustably locked on the trolley body through the strip-shaped groove locking part, and the pressing part presses against the strip-shaped groove locking part.

[0013] A scraping plate is further provided at the front end of the trolley body.

[0014] The scraping plate is connected with a scraping adjustment mechanism, which includes a swing frame and a scraping cylinder; the swing frame is arranged at the front end of the trolley body, the scraping plate is installed on the swing frame, and the scraping cylinder is arranged between the trolley body and the swing frame to drive the swing frame and the scraping plate thereon to perform a swinging scraping action.

[0015] An inner nest is provided in the material cavity. The bottom of the inner nest is set higher than the bottom of the material cavity, and a drawplate groove for arranging the drawplate is formed between the two.

[0016] The inner nest has a U-shaped structure, and the two bent parts of the U-shaped structure are designed into arc-shaped structures.

[0017] The upper end of the inner nest extends upward out of the material cavity to form a shielding edge.

[0018] The plate end of the drawplate is set as a pointed end with a trapezoidal shape in the thickness direction, and both ends of the plate end are set as a chamfered structure; the corresponding two end corners of the discharge port are set as arc-shaped structures.

[0019] The fabric trolley is equipped with a trolley sensing mechanism, which includes a first sensor and a second sensor, and the first sensor and the second sensor respectively sense and detect the back-and-forth state of the fabric trolley.

[0020] After adopting the above scheme, the beneficial effect of the material distribution trolley of the present invention compared with the prior art is that: the design idea of ​​uniform material distribution of the trolley is innovatively realized by using a draw plate to adjust the opening of the material outlet, and the timing of action is during the material discharge process of the material outlet (traditionally, it is after the material discharge is completed); when the material is discharged from the material outlet, the draw plate driving unit controls the draw plate to perform reciprocating pulling and pulling actions (the pulling and pulling action mode can be pre-set and flexibly changed and adjusted), and a unique material spreading mode controlled by the opening of the material outlet is obtained, and the material discharge amount is controlled by controlling the opening of the material outlet, and finally the effect of uniform material distribution is achieved when the material discharge is completed. Further, the material distribution trolley can also be configured with a vibrator. During the material discharge process, the vibrator vibrates appropriately to loosen the base material to avoid the problem of material jamming. This also further ensures the effectiveness and accuracy of controlling the material discharge amount by controlling the opening of the material outlet, and finally achieves a uniform material distribution effect with high efficiency and high uniformity.

[0035] The case is further described in detail below in conjunction with specific implementation methods.

[0036] This case involves a material distribution trolley 300, which is mainly used in the base material distribution process of block forming. Figure 1-5 As shown, the material distributing trolley 300 mainly includes a trolley body 31 , a drawer plate 32 and a drawer plate driving unit 33 .

[0037] The trolley body 31 has a material cavity 311, and the bottom of the material cavity 311 is hollowed out to form a discharge port 312. The material cavity 311 and the discharge port 312 are existing well-known structures. The core invention of this case lies in the design of the drawer 32. The drawer 32 is movably mounted on the trolley body 31. The drawer 32 is driven by the drawer drive unit 33 to perform a pulling action to adjust the opening of the discharge port 312, that is, it is driven by the drawer drive unit 33 to drive the drawer 32 to move to achieve flexible adjustment of the opening size of the discharge port 312. The two limit states of the discharge port 312 opening adjustment are the fully closed state and the fully open state of the discharge port 312.

[0038] The trolley body 31 is set with a reference direction, the cloth direction is from the back to the front, the draw plate 32 is set behind the discharge port 312, and the pulling direction is the front-to-back direction. In the initial state of cloth, the draw plate 32 moves forward to completely close the discharge port 312; during the cloth process, the opening of the discharge port 312 is adjusted with the front end of the discharge port 312 as the opening end. With this design, the cloth direction of the trolley is consistent with the opening adjustment direction, which is conducive to effectively controlling the uniform cloth effect. Of course, the design of the draw plate 32 is not limited to this direction limitation.

[0039] The pumping plate driving unit 33 can be in various forms, as long as it can drive the pumping plate 32 to move back and forth. In a specific embodiment, the pumping plate driving unit 33 is in the form of a cylinder. In order to facilitate the coordinated installation of the pumping plate driving unit 33 and the pumping plate 32, the pumping plate driving unit 33 and the pumping plate 32 are transitionally connected through a receiving plate 331.

[0040] In this way, the material distribution trolley 300 of this case adopts a completely different uniform material distribution concept from the traditional one. The traditional design concept is to add relevant material distribution components inside the trolley. The material distribution operation mode is that after the base material in the trolley is discharged from the discharge port, the uneven material distribution phenomenon of the completed material distribution is improved by the action of the material distribution component. This case has an original design concept, which adopts the method of adjusting the opening of the discharge port by drawing a plate. The material distribution operation mode is that the material distribution is carried out during the discharge of the material from the discharge port; specifically, when the material is discharged from the discharge port 312, the drawing plate driving unit 33 controls the drawing plate 32 to perform a reciprocating pulling action, so as to obtain a unique uniform material spreading mode controlled by the discharge port opening. The material discharge amount is controlled by controlling the opening of the discharge port 312, so as to finally achieve the effect of uniform material distribution at the same time as the material discharge is completed.

[0041] The reciprocating pulling action of the draw plate 32 means that during the material feeding process, the draw plate 32 does not only increase the opening in one direction (backward), but the overall backward direction (with a forward return action in the middle) performs a reciprocating gradual opening (with a decreasing opening in the increasing trend) action. The pulling action mode is comprehensively set according to the speed of the trolley cloth, the total amount of base material, the material feeding characteristics of the base material, the size of the cavity of the receiving mold, etc. The setting can be simulated and set in advance, and the setting is not unique. Multiple modes can be designed according to actual conditions, and flexible changes and adjustments can be made according to different actual conditions (such as different mold cavities, different total amounts of base materials, etc.).

[0042] In a preferred embodiment, the material distribution trolley 300 further includes a vibrator 34, which is preferably installed on the trolley body 31 at a position corresponding to the material cavity 311, and preferably at an opening end position corresponding to the opening adjustment of the discharge port 312 (corresponding to the preferred embodiment, the front end of the discharge port 312). In a specific embodiment, the vibrator 34 is a pneumatic vibrator, and two vibrators are arranged side by side at the front end of the trolley body 31. During the material feeding process (especially in the initial stage), the opening of the discharge port 312 is relatively small, and problems such as base material stagnation and material jamming may occur, and the material cannot be fed normally, which may affect the overall material feeding effect. Therefore, during the material feeding process, the vibrator 34 is used to vibrate appropriately to make the base material (the base material at the open end position adjusted by the opening of the discharge port 312) vibrate and loosen appropriately, ensuring that the base material can be fed according to the amount corresponding to the opening of the discharge port, thereby ensuring the effectiveness and accuracy of "controlling the material feeding amount at any time by controlling the opening of the discharge port", and ultimately achieving a uniform material feeding effect with high efficiency and high uniformity.

[0043] In the preferred embodiment, the performance of the pulling and pulling action of the draw plate 32 directly determines the performance of controlling the opening of the material outlet, that is, the material leveling performance. Therefore, the draw plate 32 in this case is also equipped with a draw plate guide mechanism 35, which is used to improve the stability and accuracy of the action of the draw plate 32. The specific design scheme of the draw plate guide mechanism 35 has two groups arranged on the left and right sides of the draw plate 32, and each group of the draw plate guide mechanism 35 includes a guide rod 351, a guide sleeve 352 and a connecting side plate 353. The guide rod 351 is arranged on the trolley body 31 along the front-back direction, and the guide sleeve 352 is movably sleeved on the guide rod 351, and the guide sleeve 352 is integrally connected with the draw plate 32 through the connecting side plate 353. The draw plate 32 needs to be movable to cooperate with the discharge port 312. In order to avoid the influence of the draw plate guide mechanism 35 on the material chamber 311, the draw plate guide mechanism 35 is arranged outside the trolley body 31, so that the draw plate guide mechanism 35 is connected to the draw plate 32 by connecting the side plates 353. The corresponding side wall of the trolley body 31 is provided with a through hole 313 for connecting the side plates 353 to play the role of connecting the inside and outside. The through hole 313 needs to extend to the part corresponding to the material chamber 311. In order to avoid the influence on the material chamber 311, it will be solved by designing an internal nesting, which will be explained later. In addition, the left and right ends of the receiving plate 331 integrally arranged with the draw plate 32 can also be integrally connected to the connecting side plates 353 of the left and right groups, thereby strengthening the precise guiding role played by the draw plate guide mechanism 35.

[0044] In the preferred embodiment, the reciprocating pulling and pulling action of the draw plate 32, in order to effectively grasp its state, the draw plate 32 is also equipped with a draw plate sensing mechanism 36, which is used to understand the dynamics of the draw plate 32 during operation. A preferred embodiment of the draw plate sensing mechanism 36 includes a first sensor 361 and a second sensor 362, which are arranged on the trolley body 31 in a front-to-back manner, and are used to sense and detect the two limit states corresponding to the draw plate 32. The draw plate 32 is preferably provided with a sensing part 363 for cooperative sensing. When the draw plate 32 is in a state of fully closing the discharge port in the front, the second sensor 362 is just opposite to the sensing part 363, and sensing detection is achieved; when the draw plate 32 is in a state of fully opening the discharge port in the rear, the first sensor 361 is just opposite to the sensing part 363, and sensing detection is achieved. In the following design, the material cavity 311 is an adjustable structure, which corresponds to the position change of the two limit states. Therefore, in the design, the first sensor 361 and the second sensor 362 are set in a flexible and adjustable position manner, and the specific embodiment adopts a strip groove locking fit method to achieve it.

[0045] In a preferred embodiment, in order to improve the material application performance of the material distribution trolley, the material cavity 311 is designed to be a capacity-adjustable structure. In a specific embodiment, a material cavity adjustment plate 37 is provided on the trolley body 31, and the material cavity adjustment plate 37 is arranged as the cavity wall (the specific embodiment is the rear cavity wall) of the material cavity 311. The capacity of the material cavity is adjusted by changing the position of the material cavity adjustment plate 37. The lower end of the material cavity adjustment plate 37 extends to the discharge port 312, serving as the edge of the discharge port 312 (the specific embodiment is the rear edge), thereby adjusting the size of the discharge port 312. The material cavity adjustment plate 37 is preferably designed to be inclined to facilitate the material receiving and unloading functions of the material cavity. In the specific design, the material cavity adjustment plate 37 adopts a two-inclined surface structure with different inclination angles.

[0046] The material cavity adjustment plate 37 is designed to be adjustable, and there are many ways to adjust it. In the preferred embodiment of this case, the material cavity adjustment plate 37 is connected to a plate adjustment mechanism, which includes a strip groove locking member 371 and a top tightening member 372. The strip groove locking member 371 has two groups, which are symmetrically arranged on the left and right sides of the trolley body 31 (the specific embodiment is arranged on the inner nesting, and the inner nesting is fixed to the trolley body 31). The strip groove locking member 371 is a slot plate with a strip groove, which extends forward and backward. The slot plate is locked in an adjustable front and rear position through the strip groove. The material cavity adjustment plate 37 is connected to the front end of the slot plate, thereby realizing the front and rear position adjustment. The top tightening member 372 is adjustable and locked on the trolley body 31, and is supported at the rear end of the slot plate. The top tightening member 372 plays an adaptive top holding and limiting role after the slot plate position is adjusted, which plays a role in stabilizing the material cavity adjustment plate 37.

[0047] In a preferred embodiment, a scraper plate 39 is further provided at the front end of the trolley body 31. After the trolley has finished distributing materials, it is used to further flatten the base material below and scrape off excess materials during the process of returning. The distributing trolley 300 is also equipped with a bottom plate at the return position, and a residual material recovery area corresponding to the residual material scraped back by the scraper plate is formed on the bottom plate. On the one hand, it can be used to avoid the problem of material leakage in the material cavity. On the other hand, the residual material scraped back by the scraper plate 39 can be scraped to the corresponding residual material recovery area of ​​the bottom plate in front of the trolley body 31 for recovery. Here, when the trolley body 31 distributes materials next time, the recovered residual material can be brought back to the mold cavity accordingly, thereby avoiding the problem of base material waste.

[0048] Further, in order to enhance the scraping effect of the scraping plate 39 and prevent the scraping plate 39 from possibly affecting the back-and-forth movement of the trolley body 31, the scraping plate 39 is designed as an adjustable structure, that is, the scraping plate 39 is connected with a scraping adjustment mechanism, and the scraping adjustment mechanism includes a swing frame 391 and a scraping cylinder 392. The swing frame 391 is arranged at the front end of the trolley body 31 to swing up and down. The swing frame 391 has a cross plate portion and two ear portions connected to both ends of the cross plate portion, and the two ear portions are movably hinged on the side wall of the trolley body 31. The scraping plate 39 is installed on the cross plate portion of the swing frame 391, and the scraping cylinder 392 (specifically, two groups are provided) is pivotally connected between the trolley body 31 and the swing frame 391. Herein, through the telescopic action of the scraping cylinder 392, the swing frame 391 is driven to swing in an up-and-down arc, and then the scraping plate 39 swings downward appropriately to perform an arc-shaped scraping action (which is beneficial for effective scraping), and swings upward appropriately to make way.

[0049] In a preferred embodiment, an inner nest 38 is provided in the material cavity 311, and the design of the inner nest 38 brings various benefits. First, the bottom of the inner nest 38 is set higher than the bottom of the material cavity 311, and a drawplate groove 383 for arranging the drawplate 32 is formed therebetween, and at the same time, it is beneficial for the drawplate 32 to completely enclose the edge of the discharge port 312. Second, the inner nest 38 is specifically designed in a U-shaped structure, and the two bent portions of the U-shaped structure are designed as arc-shaped structures 382, that is, the corners of the material cavity are designed in an arc shape to prevent material accumulation. Third, the design of the inner nest 38 is also beneficial for shielding the above-mentioned through hole 313, that is, it is beneficial for the design of the through hole 313 to ensure the structural integrity of the material cavity 311 and realize effective loading. Fourth, the upper end portion of the inner nest 38 can also extend upward out of the material cavity 311 to form a shielding edge 381.

[0050] In a preferred embodiment, the plate end portion (front end portion) of the drawplate 32 is set as a pointed end portion 321 having a trapezoidal shape in the thickness direction, and both ends of the pointed end portion 321 are set as chamfered structures 322; at this time, the corresponding two end corners of the discharge port 312 are set as arc-shaped structures (in the form of the inner nest 38 being designed, that is, the arc-shaped structure 382). With such a design, on the premise of ensuring excellent opening adjustment of the drawplate 32 for the discharge port 321, the assembly performance of the drawplate 32 is improved, which is beneficial for its smooth and effective back-and-forth movement.

[0051] In a preferred embodiment, the cloth trolley 300 is connected with a trolley driving unit to drive the cloth trolley 300 to move back and forth for cloth distribution. A traveling wheel set 314 may also be provided on the trolley body 31 to support the cloth trolley 300 and related mechanisms to achieve the traveling function.

[0052] In a preferred embodiment, the cloth trolley 300 is further provided with a trolley sensing mechanism, which includes a first sensor and a second sensor, and the first sensor and the second sensor respectively sense and detect the forward and backward movement of the cloth trolley 300. The retaining edge 381 can be used to cooperate with the first sensor and the second sensor to realize the sensing effect.
