Description

Technical Field

[0001] The invention relates to the technical field of agricultural product transportation, in particular to a transportation device for food processing. Background Art

[0002] In the process of food processing, spiral elevators are usually used as conveying devices for food raw materials and agricultural products. When the spiral elevator is in use, the flowing solid materials (such as flour, soybeans, grains and other solid materials with a certain fluidity) conveyed to the discharge port of the spiral elevator will be simultaneously affected by gravity, the inertial force of the spiral conveyor and the forward thrust of the flowing solid materials conveyed at a low position on the flowing solid materials at the discharge port. Under the superposition of these three forces, the flowing solid materials at the discharge port of the spiral elevator will quickly rush out of the discharge port. The flowing solid materials that quickly rush out of the discharge port are easy to break when they collide with each other and equipment components around the discharge port due to their high speed and high impact force, such as some brittle agricultural raw materials (such as soybeans, grains, etc.), affecting subsequent food processing.

[0003] And because the flowing solid material rushes out of the discharge port quickly, it is likely to scatter around the discharge area, causing the flowing solid material to splash instead of accurately falling into the predetermined collection device. This will also cause chaos in the workplace and increase the workload of cleaning. At the same time, it will make the amount of food raw materials entering the next production link inconsistent, causing subsequent food processing links to be affected.

[0004] Therefore, the present invention provides a conveying device for food processing. Summary of the invention

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

After completion, the user can start the conveying motor 14 through an external controller, so that the output shaft of the conveying motor 14 drives the auger 13 to rotate, so that the flowing solid materials inside the conveying pipe 12 move along the rotation direction of the spiral conveying disk of the auger 13, so that the flowing solid materials are gradually lifted from the bottom end of the conveying pipe 12 to the top end of the conveying pipe 12 until the flowing solid materials are discharged from the inside of the discharge pipe 15 to the outside.

[0025] The material discharge pipe 15 is provided with a material discharge blocking assembly, which includes a support frame 21, which is fixedly connected to the top outer wall of the material discharge pipe 15, and a servo motor 22 is installed at one end of the support frame 21 away from the material discharge pipe 15, and the output shaft of the servo motor 22 faces the bottom, and a turntable 23 is fixedly connected to the output shaft of the servo motor 22, and two material discharge troughs are symmetrically provided on the turntable 23, and two inner tubes 24 are fixedly connected below the material discharge troughs, and the outer walls of the two inner tubes 24 are each sleeved with an outer tube 25, and the bottoms of the outer walls of the two outer tubes 25 are each rotatably connected with a rotating shaft 26, and two torsion springs 27 are symmetrically sleeved on the two rotating shafts 26, and the two ends of the torsion spring 27 are respectively fixedly connected to the outer tube 25 and the rotating shaft 26, and the two rotating shafts 26 are each fixedly connected with a side away from the outer tube 25. The stop block 28 and the bottom cover plate 29 are fixedly connected to the side of the two rotating shafts 26 away from the stop block 28, and the sides of the two outer tubes 25 close to each other are each fixedly connected with a connecting block 210, and the ends of the two connecting blocks 210 close to each other are slidably connected to a track disk 211, and the inner annular surface of the track disk 211 is fixedly connected with a bearing block 212, and the bottom of the bearing block 212 is fixedly connected with a connecting column 213, and the bottom end of the connecting column 213 is fixedly connected with a connecting plate 214, and the end of the connecting plate 214 away from the connecting column 213 extends to the bottom of the discharge pipe 15, and the end of the connecting plate 214 away from the connecting column 213 is installed with an electric telescopic rod 215, and the end of the electric telescopic rod 215 away from the connecting plate 214 is fixedly connected with a suspension rod 216, and the top of the suspension rod 216 is fixedly connected to the outer wall of the discharge pipe 15.

[0026] Among them: Reference Figure 3 , Figure 5 as well as Figure 7 As shown, the bottom end of the outer tube 25 is set to be open, and the bottom cover plate 29 is adapted to the outer tube 25 .

[0027] Among them: Reference Figure 4 As shown, the connection block 210 and the track plate 211 are connected in a limited sliding manner. Specifically, the up and down movement of the connection block 210 can drive the track plate 211 to move up and down synchronously.

[0028] Among them: Reference Figure 3 As shown, the two abutments 28 are in abutment with the bottom annular surface of the track plate 211 .

[0029] Among them: Reference Figure 3 , Figure 8 As shown, the bottom of the track disk 211 is set as an uneven annular surface, specifically: the side of the bottom of the track disk 211 close to the discharge pipe 15 is set as a shorter plane, hereinafter referred to as the loading position, and the side of the bottom of the track disk 211 away from the discharge pipe 15 is set as a higher plane, hereinafter referred to as the discharge position. More specifically: the lower and higher parts of the bottom annular surface of the track disk 211 are connected by an arc surface, which serves to facilitate the contact movement of the resistance block 28.

[0030] Among them, the end of the electric telescopic rod 215 connected to the suspension rod 216 is a fixed end, and the end of the electric telescopic rod 215 connected to the connecting plate 214 is a telescopic end.

[0031] Among them: Reference Figure 3 As shown, Figure 3 A downstream food processing device is arranged at the bottom of the outer tube 25 on the right side.

[0032] The servo motor 22 is a prior art, and has controllable and programmable characteristics. Here, the output shaft of the servo motor 22 is programmed to rotate as follows: the output shaft of the servo motor 22 rotates 180 degrees, and then stops for a short period of time, which is a cycle, and the cyclic operation is performed. Specifically, the output shaft of the servo motor 22 drives the turntable 23 to rotate 180 degrees, that is, the feed trough of the servo motor 22 is connected to the outer tube 25, and stops for a period of time, and then continues to rotate.

[0033] Among them: In the initial state, that is, before the conveying work starts, Figures 2 to 8 In the state shown in the figure, one of the discharge troughs on the turntable 23 is correspondingly connected to the bottom end of the discharge pipe 15, that is, one of the inner tubes 24 and the outer tube 25 is connected to the inside of the discharge pipe 15, and the bottom cover plate 29 and the stop block 28 located at the bottom of the discharge pipe 15 are in a horizontal state, and the stop block 28 is in contact with the feeding position of the track disk 211. The two torsion springs 27 on one side of the discharge pipe 15 are in an elastic deformation state, specifically: the elastic reset of the torsion spring 27 will flip the bottom cover plate 29 downward, but the stop block 28 is in contact with the track disk 211, so that the bottom cover plate 29 will cover the bottom of the outer tube 25 close to the side of the discharge pipe 15, and the inner tube 24, the outer tube 26 and the bottom cover plate 29 form an enclosed space.

[0034] The bottom cover plate 29 and the stop block 28 on the side away from the discharge tube 15 are in an inclined state. Specifically, the stop block 28 contacts the discharge position of the higher plane of the track disk 211, so that the bottom of the outer tube 25 on this side is in an open state, and the two torsion springs 27 on the side away from the discharge tube 15 do not produce elastic deformation.

[0035] When the material discharge blocking assembly is in operation, the flowing solid material in the above text is rotated by the auger 13, thereby driving the flowing solid material to be transported upward inside the conveying pipe 12 to the position of the material discharge pipe 15, and enters the closed cavity formed by the inner tube 24, the outer tube 25 and the bottom cover plate 29 close to the side of the material discharge pipe 15.

[0036] When the flowing solid material enters the inner tube 24 and the outer tube 25 near the side of the discharge tube 15, the user can start the servo motor 22 through the external controller to rotate the output shaft of the servo motor 22. At this time, the output shaft of the servo motor 22 drives the turntable 23 to rotate 180 degrees. Since the inner tube 24, the outer tube 25, the rotating shaft 26 and the bottom cover plate 29 are symmetrically arranged in two groups on the turntable 23, the turntable 23 will drive Figure 3 The two groups of inner tubes 24, outer tubes 25, rotating shaft 1 26, bottom cover plate 29 and other structures symmetrically arranged on the left and right sides of the middle part are interchanged; Specifically, as the inner tube 24 carrying the flowing solid material rotates and moves, the inner tube 24 drives the outer tube 25 to move synchronously, and the outer tube 25 drives the connecting block 210, the bottom cover plate 29, and the stop block 28 to move synchronously. When the inner tube 24 moves to the unloading position of the track disk 211, the flowing solid material inside the inner tube 24 and the outer tube 25 is pressed down by gravity and the elastic restoring action of the two torsion springs 27, so that the rotating shaft 26 rotates until the stop block 28 contacts the unloading position of the track disk 211. At this time, Figure 8 The state shown in the figure, that is, the rotating shaft 26 drives the bottom cover plate 29 to rotate downward, so that the bottom of the outer tube 25 is no longer sealed, and the flowing solid materials inside the inner tube 24 and the outer tube 25 can be discharged to the outside.

[0037] In the above process of discharging the flowing solid material, the function of the torsion spring 27 is to prevent the flowing solid material inside the inner tube 24 from losing weight as it is discharged, thereby preventing the downward pressure applied to the bottom cover 29 from being insufficient, resulting in a reduction in the opening between the outer tube 25 and the bottom cover 29, and restricting the discharge of the flowing solid material. The setting of the torsion spring 27 can ensure that when the stop block 28 abuts against the unloading position of the track disk 211, the opening angle between the outer tube 25 and the bottom cover 29 is fixed, thereby ensuring uniform speed and complete discharge of the flowing solid material.

[0038] During the rotation of the turntable 23, that is, when the two discharge troughs are misaligned with the bottom end of the discharge pipe 15, since the upper surface of the turntable 23 is in contact with the bottom end of the discharge pipe 15, the flowing solid material inside the conveying pipe 12 will temporarily accumulate in the cavity formed between the discharge pipe 15 and the turntable 23, so as to achieve a blocking effect on the discharge of the flowing solid material from the discharge pipe 15.

[0039] When the above flowing solid materials are discharged, the output shaft of the servo motor 22 continues to rotate 180 degrees, and the set of inner tubes 24 and outer tubes 25 that have completed the discharge work return to the position connected to the inside of the discharge tube 15, that is, Figure 3 The position on the left side of the middle, specifically: during the rotation of the outer tube 25, the stop block 28 moves to contact and fit with the loading position of the track disk 211, so that the bottom cover plate 29 is re-fitted with the bottom end of the outer tube 25 and elastically deforms the torsion spring 27.

[0040] Reference Figure 3 and Figure 4 As shown, before the existing structures such as the base frame 11 and the conveying pipe 12 lift and convey the flowing solid materials, the user controls the movement of the telescopic end of the electric telescopic rod 215 through the external controller. Here, the control of the extension of the telescopic end of the electric telescopic rod 215 is taken as an example: the telescopic end of the electric telescopic rod 215 extends, driving the connecting plate 214 to move downward. At this time, the connecting plate 214 drives the bearing block 212 to move downward synchronously through the connecting column 213, and the bearing block 212 drives the track plate 211 to move downward. Since the track plate 211 is connected to the two connecting blocks 210 in a limited sliding connection, the track plate 211 is moved downward. The downward movement of the tracking plate 211 can drive the two outer tubes 25 to move downward through the two connecting blocks 210, that is, the two outer tubes 25 slide downward on the outer walls of the corresponding inner tube 24, so that the height of the space formed between the inner tube 24, the outer tube 25 and the bottom cover plate 29 becomes higher, that is, the volume between the inner tube 24, the outer tube 25 and the bottom cover plate 29 becomes larger. When the volume reaches the single unloading volume required by the user, the user stops extending the telescopic end of the electric telescopic rod 215 through the external controller. At this time, the volume of the enclosed space formed by the inner tube 24, the outer tube 25 and the bottom cover plate 29 is fixed.

[0041] The above describes Figure 3 The operation process of the inner tube 24, outer tube 25 and other structures on the left rotating one circle, combined with what is known above, that is, the process of the turntable 23 rotating one hundred and eighty degrees, can realize the loading and unloading of the flowing solid material inside the discharge pipe 15, specifically: through the operation of the discharge blocking component, the existing continuous unloading process is converted into intermittent unloading, so that the flowing solid material discharged from the discharge pipe 15 is blocked to a certain extent, avoiding the flowing solid material from rushing out of the discharge pipe 15 quickly due to gravity, the inertia force of the spiral conveyor and the thrust generated by the flowing solid material transported at a low place.

[0042] At the same time, intermittent unloading is achieved through the operation of the unloading blocking component, so that the flowing solid material does not flow out of the outer tube 25 in large quantities at one time, but is unloaded from the outer tube 25 in small batches, thereby reducing the impact force of the flowing solid material. For powdered flowing solid materials such as flour and granular flowing solid materials such as beans, this can effectively reduce the splashing of flowing solid materials, ensure the consistency of the quantity and weight of food raw materials entering the next production link, and avoid workplace chaos and increased cleaning workload caused by splashing of flowing solid materials.

[0043] The user can adjust the speed of the intermittent unloading function by setting the rotation speed and pause time of the servo motor 22, and adjust the volume of the intermittent unloading function by controlling the extension of the telescopic end of the electric telescopic rod 215, so that the user can accurately control the unloading speed and flow rate of the flowing solid material, and can flexibly meet the diverse needs of food processing and production, so as to adapt to the base frame 11, conveying pipe 12, auger 13 and other structures to improve the speed and quantity of conveying flowing solid materials, and at the same time can adapt to the supply speed and quantity of flowing solid materials required by the downstream food processing and handling equipment at the unloading point, thereby improving the versatility of the unloading blocking component.

[0044] Embodiment 2: The existing lifting and conveying is to push the flowing solid material forward by the auger 13, and the auger 13 will not extend into the discharge pipe 15. When it is at the position of the discharge pipe 15, the pushing force of the auger 13 on the flowing solid material gradually decreases, and the flowing solid material is mainly discharged from the discharge pipe 15 by gravity and the subsequent material thrust. However, when it is at the position of the discharge pipe 15, due to the reduction in the pushing force of the auger 13 on the flowing solid material, the flow speed of the flowing solid material inside the discharge pipe 15 is reduced, and it is easy to stagnate in certain areas, especially for flour with high viscosity such as flour containing a certain humidity. The friction and adhesion between the flowing solid materials and between the flowing solid materials and the inner wall of the discharge pipe 15 increase, and they are easy to stick to each other and aggregate, thereby condensing into blocks inside the discharge pipe 15, and sticking to the inner wall, affecting the discharge of the flowing solid material from the inside of the discharge pipe 15 to the outside.

[0045] Reference Figure 3 as well as Figures 9 to 13As shown, in order to solve the above-mentioned problems, an arch-breaking component is further provided inside the feeding tube 15, and the arch-breaking component includes a connecting rod 31, and the connecting rod 31 is fixedly connected to the inner wall of the feeding tube 15, and one end of the connecting rod 31 is rotatably connected to a second rotating shaft 32, and both ends of the second rotating shaft 32 pass through the connecting rod 31, and both ends of the second rotating shaft 32 are respectively fixedly connected to a circular plate 33, and one end of the connecting rod 31 close to the second rotating shaft 32 is symmetrically fixedly connected to two sleeves 34, and the two sleeves 34 are respectively sleeved on the two ends of the second rotating shaft 32, and a second torsion spring 35 is respectively sleeved on the two ends of the second rotating shaft 32, and the two ends of the second rotating shaft 32 are respectively sleeved with a second torsion spring 35, and the second torsion spring 35 is The two ends of 35 are fixedly connected to the connecting rod 31 and the circular plate 33 respectively, a swing rod 36 is fixedly connected to the rotating shaft 2 32, and two telescopic tubes 37 are symmetrically fixedly connected to the top of the swing rod 36, and the two telescopic tubes 37 are set to be hollow, and the end of the telescopic tube 37 connected to the swing rod 36 is the fixed end, and the end of the telescopic tube 37 away from the swing rod 36 is the telescopic end, and the telescopic ends of the two telescopic tubes 37 are respectively fixedly connected to a rubber ball 38, and a spring 39 is respectively arranged inside the two telescopic tubes 37, and the two ends of the spring 39 are respectively fixedly connected to the swing rod 36 and the rubber ball 38.

[0046] The bottom end of the swing rod 36 is located on the rotation path of the turntable 23 . Specifically, the rotation of the turntable 23 can drive the swing rod 36 to rotate on the connecting rod 31 .

[0047] The two sleeves 34 are tightly matched with the circular plate 33 on the same side. The function of the sleeves 34 is to prevent the flowing solid material inside the feeding tube 15 from affecting the elastic deformation of the two torsion springs 35 .

[0048] Among them: In the initial state, that is, Fig.12 In the state shown in , the inner tube 24 is connected to the feed tube 15, at which time the rocker arm 36 is in a vertical state, and the two torsion springs 35 and the two springs 39 do not produce elastic deformation.

[0049] When the arch breaking assembly is in use, the material discharge blocking assembly is in operation, specifically: the turntable 23 rotates until the inner tube 24 is misaligned with the bottom end of the material discharge tube 15. At this time, as the turntable 23 rotates, the inner wall of the inner tube 24 contacts the bottom end of the swing rod 36, and the swing rod 36 is driven to rotate on the connecting rod 31. During this process, the two torsion springs 35 are elastically deformed, and the top end of the swing rod 36 is tilted toward the inner wall of the material discharge tube 15, so that the rubber ball 38 on the tilted side contacts the inside of the material discharge tube 15, and at the same time, the telescopic end of the telescopic tube 37 on this side is contracted, and the spring 39 is elastically compressed; As the inner tube 24 is misaligned with the bottom end of the discharge tube 15, when the turntable 23 rotates to the bottom end of the discharge tube 15 and is blocked, the flowing solid material continuously enters the discharge tube 15 and accumulates on the top of the turntable 23 as the auger 13 continues to rotate and lift the conveyor. At the same time, the tilted state of the swing rod 36 and the elastic deformation of the spring 39 and the torsion spring 35 are limited. When the turntable 23 rotates to the inner tube 24 to reconnect with the discharge tube 15, the flowing solid material in the discharge tube 15 enters the inner tube 24. At the same time, the turntable 23 no longer limits the elastic recovery of the torsion spring 35. The swing of the top end of the swing arm 36 will stir the flowing solid material inside the discharge pipe 15, so that the flowing solid material that has condensed into blocks inside the discharge pipe 15 is broken up. The broken up flowing solid material falls into the inner tube 24 under the action of gravity and the joint action of the falling of other flowing solid materials, which can ensure that the flowing solid material inside the discharge pipe 15 can smoothly enter the inner tube 24, provide a material basis for the operation of the discharge blocking component, and ensure that the flowing solid material entering the inner tube 24 each time is at a uniform speed and a uniform amount.

[0050] When the swing arm 36 swings, the rubber balls 38 on both sides of the top of the swing arm 36 will hit the inner wall of the discharge pipe 15, causing the discharge pipe 15 to vibrate, which can destroy the adhesion between the flowing solid material and the inner wall of the discharge pipe 15, thereby weakening the adsorption effect between the flowing solid material and the discharge pipe 15, causing the flowing solid material to fall off from the inner wall of the discharge pipe 15, so that this part of the flowing solid material can fall into the inner tube 24, avoiding the flowing solid material from adhering to the inner wall of the discharge pipe 15, and effectively reducing the risk of blockage inside the discharge pipe 15.
