Description

Technical Field

[0001] The invention relates to the technical field of rice processing, in particular to a conveying device used for rice processing. Background Art

[0002] Rice is processed by husking rice. When the rice is collected at the raw material distribution center, it is transported to the processing plant by means of transportation, or when the rice is collected in the field, a grain conveyor belt can be used to build a transportation route, so that the bulk rice can be shoveled onto the grain conveyor belt by means of a forklift or manual labor, and then transported by the grain conveyor belt to a suitable area for direct loading or bagging and then loading on a truck for transportation;

[0003] Generally, grain conveyors adopt the design of V-shaped rollers, which makes the middle of the conveyor belt concave, so that the material is placed in the center, reducing material leakage and improving the conveyor belt's transportation efficiency. However, due to its shape, the V-shaped roller may increase the deviation tendency of the conveyor belt to a certain extent. If the material is unevenly distributed on the conveyor belt, especially in the V-shaped roller area, it may produce asymmetric lateral force on the conveyor belt, causing deviation and even causing the belt to fall off the roller, which is inconvenient. In addition, when rice is shoveled onto the grain conveyor belt manually or by tools such as forklifts, it is difficult to operate manually. The landing point of the rice may be offset, and the V-type rollers are mostly composed of two inclined rollers. The landing point deviation may cause one of the V-type rollers to be subjected to more force, causing the roller to deform, which is inconvenient. In addition, most materials are shoveled onto the conveyor belt by shoveling. When unloading the materials, they need to be released slowly so that the materials are slowly poured onto the conveyor belt and evenly spread on the belt for transportation. If the pouring speed is too fast, the materials may accumulate on the belt part, causing the belt part to be subjected to excessive force, affecting the smoothness of the belt conveying, and the belt may be damaged during the conveying process.

[0012] Furthermore, one end of each of the two rotating frames on the same adjustment component is fixedly connected with a return spring, and one end of each of the two return springs is fixedly connected to one side of the adjacent U-shaped block.

[0013] The invention further lies in that: both the top and bottom sides of the two supporting rods on the same adjusting component are fixedly connected with sliding layers.

[0014] Furthermore, the two rotating frames have hook-shaped structures at their opposite ends, and the two rotating frames are respectively slidably engaged with the outer walls of the two lifting rods, the outer walls of the two lifting rods are fixedly connected with multiple sliding rods, one side of the two vertical plates is provided with multiple sliding grooves, the multiple sliding grooves on any vertical plate correspond one-to-one to the multiple sliding rods on adjacent lifting rods, and any sliding rod passes through the corresponding sliding grooves, the other sides of the two vertical plates are fixedly connected with electric push rods, and the movable ends of the two electric push rods are fixedly connected with moving plates, the top surfaces of the two moving plates are fixedly connected with multiple sliding frames, the multiple sliding frames on the same moving plate correspond one-to-one to the multiple sliding rods on adjacent lifting rods, and the outer walls of the multiple sliding rods on any lifting rod are slidably sleeved with the inner walls of the multiple sliding frames on the adjacent moving plates.

[0016] The invention further lies in that: the ends of two support rods on the same adjustment assembly which are away from each other are both rotatably connected with pulleys.

[0017] Furthermore, both ends of the two lifting rods are provided with fixing rods, any fixing rod is L-shaped, and one side of any fixing rod is fixedly connected to one side of the adjacent vertical plate, both ends of the two lifting rods are rotatably connected to connecting tubes, one end of any fixing rod is rotatably connected to an insertion rod, and any insertion rod is slidably inserted into the inside of the adjacent connecting tube.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. By placing the material on the top surface of the conveying mechanism, and then using the motor to drive the roller to drive the adjacent tooth rollers to rotate, the conveying mechanism is driven to rotate between multiple rollers, so that the conveying mechanism can convey the material, and the conveying mechanism is limited by two adjacent rollers, reducing the occurrence of belt deviation, and the edge of the top surface of the conveying mechanism can be raised by using the adjustment mechanism, while the other parts of the conveying mechanism are in their original state, thereby improving the conveying capacity of the conveying mechanism and reducing the belt from falling off the roller and deviating. The material inside the conveying mechanism can be adjusted by the adjustment mechanism to make the material distribution inside the conveying mechanism more even.

[0020] 2. The motor drives the roller to rotate, driving the adjacent toothed roller to rotate, so that the toothed roller meshes with the toothed belt through its own gear teeth, thereby driving the ring-shaped belt to rotate. The ring-shaped belt is stuck between the two rollers at both ends of the same geared roller, thereby limiting the position of the ring-shaped belt. The ring-shaped belt drives the ring-shaped belt to rotate synchronously through multiple adjustment components, thereby reducing the deviation of the ring-shaped belt.

[0021] 3. By starting two electric push rods to drive the two moving plates and adjacent sliding rods to move upward, the two lifting rods are moved upward synchronously, and the adjacent connecting tubes and sliding rods are tilted. When any adjustment component has not moved to the top of the ring belt, the two rotating frames and the two supporting rods are in a parallel state. When any adjustment component moves to the fixed rod, the hook-shaped structures on the two rotating frames are naturally stuck on the fixed rod, and move along the fixed rod and the adjacent sliding rods and connecting tubes until they are stuck on the lifting rod, so that the two rotating frames rotate naturally, and the adjacent supporting rods are lifted and rotated synchronously, so that the edge of the top of the ring belt at the lifting rod part is tilted, the material is supported, and the conveying capacity of the ring belt for the material is improved;

[0022] 4. When the material falls on the circular belt, the two lifting rods can be driven back and forth by reciprocatingly driving the two electric push rods to drive the two lifting rods to move back and forth, thereby driving the edge of the circular belt to shake back and forth, so that the material on the circular belt is naturally and evenly spread due to shaking and vibration. When the material is shoveled onto the circular belt, the dumping speed can be increased, so that the material is naturally accumulated on the circular belt for a section, and then the edge of the circular belt is reciprocated to lift up, so that the material on the circular belt is redistributed and naturally spread, making the circular belt conveying more stable and improving the conveying efficiency of the circular belt.

DETAILED DESCRIPTION

[0030] 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. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] See also Figure 1-6 In an embodiment of the present invention, a conveying device for rice processing includes:

[0032] Two vertical plates 100, a plurality of toothed rollers 200 for driving, a conveying mechanism 300 for conveying materials, and an adjusting mechanism 400 for adjusting the conveying mechanism 300. Both ends of the plurality of toothed rollers 200 are fixedly connected with rotating rollers 210. The two rotating rollers 210 at the two ends of any toothed roller 200 are rotatably connected to one side of the two vertical plates 100 at opposite ends. The conveying mechanism 300 is located between the two vertical plates 100. The conveying mechanism 300 includes an annular belt 310, and an annular toothed belt 320 is arranged inside the annular belt 310. The inner wall teeth of the annular toothed belt 320 are meshed with the outer wall teeth of the plurality of toothed rollers 200. The adjusting mechanism 400 is located between the annular belt 310 and the annular toothed belt 320. The adjusting mechanism 400 includes a plurality of adjusting components and two lifting rods 460. The plurality of adjusting components are located between the annular belt 310 and the annular toothed belt 320. The two lifting rods 460 are slidably engaged with adjacent adjusting components.

[0033] Specifically, a plurality of toothed rollers 200 are arranged in a rectangular shape between two vertical plates 100, and when in use, a motor can be fixed to one vertical plate 100, and the motor shaft of the motor can pass through the adjacent vertical plates 100 and be fixedly connected to one end of the adjacent rotating roller 210, so that the motor can drive the adjacent toothed rollers 200 and the rotating roller 210 to rotate, and the toothed roller 200 meshes with the toothed gear on the annular toothed belt 320 through its own gear teeth, thereby driving the annular toothed belt 320 to rotate between the plurality of toothed rollers 200, and at the same time, when the annular toothed belt 320 rotates, it will synchronously drive the annular belt 310 to rotate through a plurality of adjustment components, and the material falls on the top surface of the annular belt 310, so that the rotating annular belt 310 can transport the material, and the two lifting rods 460 are both located at the top position of the annular belt 310, and by changing the two lifting rods 460, The height position of the lifting rod 460 is used to adjust the adjustment component located at the top of the circular belt 310, so that the adjustment component located at the top of the circular belt 310 can be driven by the lifting rod 460 to adjust and change the shape of the top of the circular belt 310, so that the opposite two sides of the top of the circular belt 310 are tilted to facilitate receiving materials, so that the materials are not easy to fall out of the outside of the circular belt 310, and the transmission power of the circular belt 310 is improved through the toothed roller 200 and the circular toothed belt 320, thereby improving the load capacity of the circular belt 310, and the top part of the circular belt 310 is deformed by the lifting rod 460 and the adjustment component, while the other parts of the circular belt 310 are not deformed, so that the circular belt 310 is not prone to belt deviation, thereby reducing the belt roller derailment.

[0034] Embodiment 1

[0035] like Figure 2-3 As shown, in this embodiment, the diameter of any roller 210 is greater than the diameter of the gear roller 200 , and the annular toothed belt 320 is embedded between the two rollers 210 on the same gear roller 200 .

[0036] In this embodiment, there is space between the rollers 210 at both ends of the same toothed roller 200 for the annular toothed belt 320 to be embedded. When the annular toothed belt 320 is embedded between two adjacent rollers 210, the annular toothed belt 320 can be limited, thereby improving the limiting effect of the annular belt 310 and preventing the annular belt 310 from deviating easily.

[0037] like Figure 2 and Figure 4-5 As shown, in this embodiment, the adjustment component includes:

[0038] The support plate 410, the connecting plate 420, the two rotating frames 430 and the two supporting rods 440, one side of the support plate 410 is fixedly connected to the outer wall of the annular toothed belt 320, one side of the connecting plate 420 is fixedly connected to the other side of the support plate 410, and the other side of the connecting plate 420 is fixedly connected to the middle part of the inner wall of the annular belt 310, the adjacent ends of the two rotating frames 430 are respectively rotatably connected to the two ends of the connecting plate 420, and the two rotating frames 430 are both slidably clamped with U-shaped blocks 431, the adjacent ends of the two supporting rods 440 are respectively rotatably connected to the two ends of the connecting plate 420, and the two supporting rods 440 are both located above the adjacent rotating frames 430, the opposite side edges of the annular belt 310 both bypass the opposite ends of the two supporting rods 440, and the opposite side edges of the annular belt 310 are respectively fixedly connected to the two arms of the adjacent U-shaped blocks 431.

[0039] During specific implementation, the endless belt 310 is connected to the endless toothed belt 320 through the connecting plates 420 and the supporting plates 410 on the multiple adjustment components, so that the endless toothed belt 320 can drive the endless belt 310 to rotate synchronously. When it has not moved to the two lifting rods 460, the two rotating frames 430 on the same adjustment component remain in parallel arrangement, and the two supporting rods 440 also remain in parallel arrangement, and the opposite side edges of the endless belt 310 are respectively located between the two supporting rods 440 and the adjacent rotating frames 430 on the same adjustment component, and the outer side wall of the endless belt 310 remains parallel to the outer side wall of the endless toothed belt 320. When any adjustment component moves to the two lifting rods 460, that is, when it moves to the top of the endless belt 310, the two rotating frames 430 can be driven to rotate upward by moving the lifting rods 460, so that the two rotating frames 430 can be pushed up. Adjacent supporting rods 440 rotate synchronously, and the middle part of the annular belt 310 is fixed on the connecting plate 420, so that the opposite sides of the annular belt 310 at the adjusting component are naturally pulled and move away from each other, so that the two U-shaped blocks 431 on the adjusting component are pulled by the annular belt 310 and move away from each other, so that the edge of the top surface of the annular belt 310 located at the lifting rod 460 is tilted, so that a larger amount of material can be carried, while the shape of the annular belt 310 at other positions remains unchanged, thereby increasing the carrying capacity of the annular belt 310. The surface of the annular belt 310 is wrinkled. When the annular belt 310 near the lifting rod 460 is tilted due to the rotation of the supporting rod 440, the annular belt 310 near the tilted position of the annular belt 310 can be stretched and deformed to a certain extent by relying on the wrinkles, and the middle part of the annular belt 310 has no wrinkles and is not easily deformed.

[0040] like Figure 4-5 As shown, in this embodiment, one end of the two rotating frames 430 on the same adjustment component is fixedly connected to a return spring 432, and one end of the two return springs 432 is fixedly connected to one side of the adjacent U-shaped block 431, and the two support rods 440 on the same adjustment component are fixedly connected to the sliding layer 442 on both the top and bottom sides.

[0041] In specific implementation, the sliding layer 442 is a coating with a smooth surface, which is used to reduce the friction between the surface of the annular belt 310 and the support rod 440, so that the annular belt 310 can move more smoothly between the support rod 440 and the adjacent rotating frame 430. After any adjustment component is detached from the two lifting rods 460, the wrinkles on the annular belt 310 will naturally recover due to its own elasticity, and the reset spring 432 will pull the adjacent U-shaped block 431 to reset, thereby pulling the opposite two side edges of the annular belt 310 that have moved back to their original positions, so that the part of the annular belt 310 away from the two lifting rods 460 can naturally recover after deformation.

[0042] like Figure 4-6 As shown, in this embodiment, the ends of the two rotating frames 430 that are away from each other are hook-shaped structures, and the ends of the two rotating frames 430 that are away from each other are respectively slidably engaged with the outer walls of the two lifting rods 460, and the outer walls of the two lifting rods 460 are fixedly connected with a plurality of sliding rods 461, and a plurality of sliding grooves 101 are opened on one side of the two vertical plates 100, and the plurality of sliding grooves 101 on any vertical plate 100 correspond to the plurality of sliding rods 461 on the adjacent lifting rods 460 one by one, and any sliding rod 461 passes through the corresponding sliding groove 101, and the other sides of the two vertical plates 100 are fixedly connected with electric push rods 450, and the two The movable ends of the electric push rods 450 are fixedly connected to moving plates 451, and multiple sliding frames 452 are fixedly connected to the top surfaces of the two moving plates 451. The multiple sliding frames 452 on the same moving plate 451 correspond one to one to the multiple sliding bars 461 on the adjacent lifting rods 460. The outer walls of the multiple sliding bars 461 on any lifting rod 460 are slidably connected to the inner walls of the multiple sliding frames 452 on the adjacent moving plates 451. Any sliding bar 461 is L-shaped, and one side of the short arm of any sliding bar 461 is an inclined surface. The opposite ends of the two support rods 440 on the same adjusting component are rotatably connected to the pulley 441.

[0043] When the lifting rod 460 is moved, the hook-shaped end of the rotating frame 430 is not easy to conflict with the sliding rod 461. When any adjusting component moves to the lifting rod 460 with the endless belt 310, the hook-shaped structures on the two rotating frames 430 will naturally hook on the two lifting rods 460 for sliding engagement, and then as the lifting rod 460 moves upward, the hook-shaped structures of the two rotating frames 430 will be driven upward by the lifting rod 460, thereby rotating the two rotating frames 430. After the two rotating frames 430 pass through the lifting rod 460 and separate from the lifting rod 460, they will be restored to their original state. When in use, the height position of the two lifting rods 460 can be adjusted by starting the electric push rod 450 to adjust the height of the moving plate 451, thereby adjusting the rotating frames 430 on the lifting rod 460. 0, so as to control the tilting degree of the edge of the portion of the endless belt 310 located between the two lifting rods 460, and when the material falls on the top of the endless belt 310, the two electric push rods 450 can be started reciprocatingly to drive the two lifting rods 460 to move reciprocatingly, so that the edge of the top portion of the endless belt 310 between the two lifting rods 460 is tilted back and forth and then falls back, so that the material on the endless belt 310 breaks the adhesion between the rice grains due to the vibration or shaking of the endless belt 310, prompting them to be redistributed and arranged to achieve a more uniform paving effect, so that the material distribution on the endless belt 310 is more uniform, so that when the material is shoveled onto the endless belt 310, the material can be quickly dumped, and then the edge of the top of the endless belt 310 located at the lifting rod 460 can be tilted back and forth, so that the material accumulated on the endless belt 310 is redistributed and naturally spread, avoiding excessive material accumulation in some areas of the belt, bearing excessive pressure, and affecting belt conveying.

[0044] Embodiment 2

[0045] On the basis of the first embodiment, by providing a fixing rod 470 and an inserting rod 471 , it is convenient for the hook structure of the rotating frame 430 to move along the fixing rod 470 and engage with the lifting rod 460 .

[0046] like Figure 4-6 As shown, in this embodiment, both ends of the two lifting rods 460 are provided with fixing rods 470, any fixing rod 470 is L-shaped, and one side of any fixing rod 470 is fixedly connected to one side of the adjacent vertical plate 100, both ends of the two lifting rods 460 are rotatably connected with connecting tubes 462, one end of any fixing rod 470 is rotatably connected with an insertion rod 471, and any insertion rod 471 is slidably inserted into the inside of the adjacent connecting tube 462.

[0047] In specific implementation, when the two lifting rods 460 are driven upward by the adjacent electric push rods 450, the ends of the two adjacent connecting tubes 462 will be driven upward, so that the connecting tubes 462 are changed from the original parallel state with the adjacent fixed rods 470 to the inclined state. When any adjusting component moves to the top of the circular belt 310, the hook-shaped structures on the two rotating frames 430 will naturally hook on the two fixed rods 470 first, and then as the adjusting component is driven to move by the circular belt 310, the hook-shaped structures on the two rotating frames 430 will be on the adjacent fixed rods 470. It slides and naturally hooks on the adjacent connecting tube 462 or the insert rod 471, and then as the annular belt 310 continues to move, the hook structures on the two rotating frames 430 naturally hook on the lifting rod 460. After the two rotating frames 430 are separated from the lifting rod 460, the hook structures on the rotating frames 430 will naturally rely on hooking on the adjacent connecting tube 462 or the insert rod 471 and the fixed rod 470 to complete the reset, so that after the lifting rod 460 moves up, the hook structure on any rotating frame 430 can still be naturally engaged with the lifting rod 460.

[0048] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
