Description

Technical Field

[0001] This invention pertains to material conveying technology, specifically the transportation of raw materials for soy sauce production, and particularly relates to a soy sauce raw material conveying device. Background Technology

[0002] Soy sauce is made by steaming soybeans or black beans, mixing them with wheat or wheat bran, and then fermenting them using koji (fermentation starter). Currently, the koji-making process commonly uses a V-shaped conveyor belt (also known as a trough-type idler conveyor belt) to transport the raw materials to a disc koji-making machine for koji production. The V-shaped conveyor belt has a recessed idler roller in the center to support the bottom, thus forming a trough under the pressure of the material. However, due to the tension at both ends of the conveyor belt, the V-shaped trough formed in this way is relatively shallow and can only hold a small amount of material. If too much material is poured into it, it will overflow the conveyor belt. Therefore, when pouring material onto the conveyor belt, the pouring speed cannot be too fast, which will result in low conveying efficiency. In addition, idler rollers cannot be installed at both ends of the V-shaped conveyor belt, so the V-shaped trough cannot be formed at both ends. When the material is conveyed to the ends, it is easy to leak from both sides, resulting in material waste. Summary of the Invention

[0003] To address the aforementioned deficiencies in the prior art, this application provides a V-shaped conveyor device that enables the conveyor belt to form a deep V-shaped groove for conveying materials, thereby increasing conveying efficiency and preventing material leakage during conveying.

[0004] To achieve the above objectives, the present invention employs the following techniques:

[0005] A V-shaped conveyor device, comprising:

[0006] Two annular tracks are symmetrically spaced and connected by a first connecting rod. The inner sides of the two annular tracks are also provided with a first annular groove. The two ends of the annular tracks and the first annular grooves are symmetrical semi-circular arcs, and the middle sections are straight lines.

[0007] Two first support frames are respectively connected to the outside of two annular tracks. Multiple transmission rods are hinged between the two first support frames. The multiple transmission rods are arranged in a straight line. The line connecting the center of the semicircular arc at both ends of one first annular slide groove and the center of the semicircular arc at both ends of the other first annular slide groove is the same as the axis of the two transmission rods at both ends. At least one end of the transmission rod is connected to the motor output shaft. The middle section of the transmission rod is fitted with a transmission gear.

[0008] The belt has a rack that meshes with a transmission gear along its length in the middle section at the bottom. The rack and the belt are connected end to end and are wrapped around the transmission gear. The belt also has multiple sets of symmetrical first connecting holes on both sides. A second connecting rod is provided in the first connecting hole. Both ends of the second connecting rod are slidably connected to the first annular groove to make the belt rotate in a V-shaped groove.

[0009] The receiving trough, located at one end of the circular track, is used to allow the conveyed material to be discharged through the receiving trough.

[0010] Furthermore, the receiving trough includes a bottom plate and a pair of side plates. The bottom plate is inclined downwards, and the pair of side plates are located above the bottom plate. One end of the pair of side plates is connected to two annular tracks respectively, and the distance between the other ends of the pair of side plates is less than the distance between the one ends of the pair of side plates.

[0011] Furthermore, a second connecting hole is provided on the side plate, and a first scraper rod is hinged in the second connecting hole with the hinge axis in the vertical direction. A spring is also connected between the first scraper rod and the annular track. Push rings are sleeved on both ends of the second connecting rod, and the top of the push ring protrudes from the top of the annular track. When the spring contracts, the first scraper rod abuts against the belt. When the push ring squeezes the first scraper rod, the spring is in a stretched state. When the push ring squeezes the first scraper rod to the maximum extent, the first scraper rod is parallel to the first connecting rod.

[0012] Furthermore, the first scraper bar is located inside the V-groove and has first bristles on its side wall facing the V-groove.

[0013] Furthermore, the first scraper bar includes a first scraper section and a second scraper section. One end of the first scraper section is hinged in the second connecting hole, and the other end is connected to the second scraper section. The included angle between the first scraper section and the second scraper section is equal to the included angle between the rack and the belt, which is used to match the V-groove.

[0014] Furthermore, the first scraping section includes a first rotating section and a second rotating section. The first rotating section is hinged in the second connecting hole, and the second rotating section is connected to the first rotating section via a hinge. The direction of the hinge's rotation axis is the same as the width direction of the second rotating section.

[0015] Furthermore, the second connecting rod is also connected to a baffle plate, which is located in the V-shaped groove formed by the belt. The inner sides of the two annular tracks are also provided with second annular grooves. The two ends of the second annular grooves are semi-circular arcs, and the middle section is straight. The center of the semi-circular arcs at both ends is the same as the center of the semi-circular arcs at both ends of the first annular groove. The side wall of the pushing ring is also connected to a limiting post, which matches the second annular groove and is located in the second annular groove.

[0016] Furthermore, a second support frame is hinged to the bottom of the two annular tracks near the receiving trough.

[0017] Furthermore, each of the two annular tracks is provided with a support seat at the top. The distance between the two support seats in the length direction of the annular track is greater than the diameter of the second connecting rod. The support seats are hinged with a second scraper rod, and the hinge axis is parallel to the length direction of the annular track. The second scraper rod is provided with second bristles on the two side walls inside the V-groove.

[0018] Furthermore, the second connecting rod has a through groove in the vertical direction, the baffle plate passes through the through groove, and both the baffle plate and the second connecting rod have matching threaded holes, with screws installed in the threaded holes to fix the baffle plate.

[0019] The beneficial effects of this invention are as follows:

[0020] 1. This device, through the structural and coordinated design of the circular track, transmission rod, and belt, enables the belt to form a V-shaped groove for transporting materials, thereby increasing conveying efficiency and effectively preventing material leakage;

[0021] 2. The first scraper bar and push ring are designed to drive the belt to rotate using only one motor, which in turn scrapes off the material adhering to the belt.

[0022] 3. The baffle plate allows the device to be placed at an angle to transport materials upwards;

[0023] 4. The structure of the second scraper bar enables it to rotate upward to clean up the material adhering to one side of the baffle when squeezed by the push ring, and to rotate downward to clean up the material on the other side of the baffle by its own gravity. Attached Figure Description

Detailed Implementation

[0035] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the implementation methods of the present invention will be described in detail below with reference to the accompanying drawings. However, the embodiments described in this invention are only some embodiments of the present invention, and not all embodiments.

[0036] This application provides a V-shaped conveying device, such as... Figures 1-10As shown, the system includes two annular tracks 1, two first support frames 2, and a belt 6. The two annular tracks 1 are connected by first connecting rods 101 and are symmetrically spaced. Each track has an inner annular groove 102. Both ends of the annular tracks 1 and the first annular grooves 102 are symmetrical semicircular arcs, while the middle sections are straight. The two first support frames 2 are respectively connected to the outer sides of the two annular tracks 1, and multiple transmission rods 3 arranged in a straight line are hinged between them. The lines connecting the centers of the semicircular arcs at both ends of one first annular groove 102 and the centers of the semicircular arcs at both ends of the other first annular groove 102 are axially aligned with the axes of the two transmission rods 3 at both ends, i.e., axially aligned with the axes of the semicircular arc sections at both ends of the first annular groove 102. In a straight line, at least one of the multiple transmission rods 3 is connected to the output shaft of the motor 4 to drive the device to operate. In this embodiment, only one transmission rod 3 is selected to connect to the output shaft of the motor 4. The middle section of the bottom of the belt 6 is provided with a rack 601 that meshes with the transmission gear 5 along its length. The rack 601 and the belt 6 are both connected end to end and are wrapped around the transmission gear 5. Multiple sets of symmetrical first connecting holes 602 are also opened on both sides of the belt 6. The first connecting holes 602 are provided with second connecting rods 603. Both ends of the second connecting rods 603 are slidably connected to the first annular groove 102 to make the belt 6 rotate in a V-shaped groove 604. The receiving groove 7 is provided at one end of the annular track 1 and is used to allow the conveyed material to be output through the receiving groove 7.

[0037] For details, please refer to Figure 1 , Figure 4 The receiving trough 7 includes a bottom plate 701 and a pair of side plates 702. The bottom plate 701 is inclined downwards, and the pair of side plates 702 are located above the bottom plate 701. One end of the pair of side plates 702 is connected to two annular tracks 1 respectively, and the distance between the other ends of the pair of side plates 702 is less than the distance between one end of the pair of side plates 702. After the receiving trough 7 is set, the material is transferred to the end of the device and then enters the next processing stage through the receiving trough 7. Because the pair of side plates 702 of the receiving trough 7 are inclined to each other, the outlet of the receiving trough 7 becomes smaller, which facilitates the collection of materials in the next processing stage.

[0038] For further details, please refer to [link / reference]. Figure 4 , Figure 5A second connecting hole 7021 is provided on the side plate 702. A first scraper rod 8 is hinged in the second connecting hole 7021 with the hinge axis in the vertical direction. A spring 801 is also connected between the first scraper rod 8 and the annular track 1. Push rings 6031 are sleeved on both ends of the second connecting rod 603. The top of the push ring 6031 protrudes from the top of the annular track 1. When the spring 801 contracts, the first scraper rod 8 abuts against the belt 6 and scrapes off the material adhering to the belt 6. When the push ring 6031 squeezes the first scraper rod 8, the spring 801 is in a stretched state, and the first scraper rod 8 rotates away from the belt 6. When the push ring 6031 squeezes the first scraper rod 8 to the maximum extent, the first scraper rod 8 is parallel to the second connecting rod 603, allowing the second connecting rod 603 to pass through. After the push ring 6031 passes through, the first scraper rod 8 abuts against the belt 6 again due to the tension of the spring 801 when it contracts, scraping off the material adhering to the belt. When transporting soy sauce raw materials, it is necessary to transport steamed soybeans and flour mixed with them. These materials have a certain degree of stickiness. This setting enables automatic cleaning of belt 6 to prevent the sticky materials from deteriorating and contaminating the materials transported later.

[0039] For details, please refer to Figure 4 The first scraper bar 8 is located inside the V-groove 604 and has a first brush bristle 802 on its side wall facing the V-groove 604. The first brush bristle 802 is positioned towards the belt 6. After the first scraper bar 8 is positioned, when the first scraper bar 8 abuts against the belt 6, the first brush bristle 802 is subjected to pressure and bends and deforms. When the push ring 6031 squeezes the first scraper bar 8 away from the belt 6 and rotates, the first brush bristle 802 gradually returns to its original shape and always remains in contact with the belt 6, thus avoiding the situation where the material cannot be scraped during the time when the first scraper bar 8 rotates away from the belt 6.

[0040] For more details, please refer to Figure 7 The first scraper bar 8 includes a first scraper section 803 and a second scraper section 804. One end of the first scraper section 803 is hinged in the second connecting hole 7021, and the other end is connected to the second scraper section 804. The included angle between the first scraper section 803 and the second scraper section 804 is equal to the included angle between the rack 601 and the belt 6, which is used to match the V-groove 604. Through this setting, the material adhering to the bottom of the V-groove 604 can also be scraped off.

[0041] For further details, please refer to [link / reference]. Figures 4-5The first scraping section 803 includes a first rotating section 8031 ​​and a second rotating section 8032. The first rotating section 8031 ​​is hinged in the second connecting hole 7021, and the second rotating section 8032 is connected to the first rotating section 8031 ​​via a hinge 8033. The rotation axis of the hinge 8033 is in the same direction as the width of the second rotating section 8032. Considering that the first scraping rod 8 is not required to work when transporting materials, and that the first scraping rod 8 will also block the material from falling when it is poured into the receiving trough 7, this setting allows the second rotating section 8032 to rotate upwards during material transport, preventing the pushing ring 6031 from contacting the first scraping rod 8. After transport is completed, the second rotating section 8032 is lowered, and the motor 4 is started to begin scraping.

[0042] For further details, please refer to [link / reference]. Figure 1 , Figures 7-9 The second connecting rod 603 is also connected to a baffle plate 9, which is located in the V-shaped groove formed by the belt 6. A second annular chute 103 is also provided on the inner side of the two annular tracks 1. The two ends of the second annular chute 103 are semi-circular arcs, and the middle section is straight. The centers of the semi-circular arcs at both ends are the same as the centers of the semi-circular arcs at both ends of the first annular chute 102. A limiting post 6032 is also connected to the side wall of the pushing ring. The limiting post 6032 matches the second annular chute 103 and is located within it. The baffle plate 9 allows the device to be placed at an angle to transport materials upwards, increasing the device's application scenarios. The matching arrangement of the second annular chute 103 and the limiting post 6032 prevents the second connecting rod 603 from rotating around its own axis during transportation, thus fixing the position of the baffle plate 9 relative to the belt 6.

[0043] For further details, please refer to [link / reference]. Figure 3 , Figure 10 Two circular tracks 1 are hinged to the bottom of the receiving trough 7 at one end, and a second support frame 104 is provided. The second support frame 104 allows one end of the device to be quickly supported and raised for upward material transport. When parallel material transport is required, the second support frame 104 can be retracted.

[0044] For further details, please refer to [link / reference]. Figure 4 , Figure 6Each of the two annular tracks 1 has a support base 105 at its top. The distance between the two support bases 105 along the length of the annular track 1 is greater than the diameter of the second connecting rod 603. The support base 105 is hinged to a second scraper rod 10. The second scraper rod 10 has second bristles 1001 on both sides of its side wall within the V-groove 604. When one of the second scraper rods 10 is squeezed by the push ring 6031, it rotates upward to clean up some material adhering to one side of the baffle plate 9, and rotates downward to clean up some material on the other side of the baffle plate 9 by its own gravity. When the other second scraper rod 10 is squeezed by the push ring 6031, it rotates upward to clean up another part of material adhering to one side of the baffle plate 9, and rotates downward to clean up another part of material on the other side of the baffle plate 9 by its own gravity.

[0045] For further details, please refer to [link / reference]. Figure 2 The second connecting rod 603 has a through groove in the vertical direction, and the baffle plate 9 passes through the through groove. Both the baffle plate 9 and the second connecting rod 603 have matching threaded holes, and screws 6034 are connected in the threaded holes to fix the baffle plate 9. The baffle plate 9 and the second connecting rod 603 are set to be detachably connected, so that the baffle plate 9 can be directly removed when the device is switched from lifting transport to parallel transport. At the same time, when the conveyor belt needs to be further cleaned and sterilized, when the baffle plate 9 is removed, the side wall of the baffle plate 9 rubs against the lower edge of the through groove wall of the second connecting rod 603, cleaning the material adhering to the baffle plate 9 again, reducing the amount of subsequent cleaning work. Specifically, the part of the baffle plate 9 protruding above the second connecting rod 603 also has a through hole 6035, which is used for people to insert their fingers or hooks to lift the baffle plate 9.

[0046] When the device is used for parallel transport, there is no need to connect the baffle plate 9. After rotating the second rotating section 8032 and the second scraper rod 10 upward, the motor 4 is started to drive the transmission rod 3, rack 601, and belt 6 to rotate, and the material can be poured into the V-shaped groove 604 to start transport. After the transport is completed, the motor 4 is kept rotating, and the second rotating section 8032 is lowered so that it contacts the belt 6, and the material adhering to the belt 6 can be scraped off. When the device is used for lifting and conveying materials, the baffle plate 9 is connected to the second connecting rod 603 to raise the discharge end. The second support frame 104 is rotated for support, and the second rotating section 8032 and the second scraper rod 10 are rotated upward to start the conveying. After the transport is completed, the motor 4 is kept rotating, and the second rotating section 8032 and the second scraper rod 10 are lowered, and the material adhering to the belt 6 and the baffle plate 9 can be scraped off.
