Moreover, after the raw materials enter the spiral delivery tray from the feed inlet, due to the bending change of the conveyor belt, the raw materials will accumulate, thus affecting the drying efficiency. In addition, the raw materials to be processed often have different volume sizes, and the drying times required for raw materials of different sizes are different, resulting in a poor overall drying effect of the raw materials.

[0032] The solution of this embodiment first provides a raw material processing and drying device. Generally, the raw material processing and drying device may include: a support blade 100, a conveyor belt 200, a driving device 300, a drying device 400, a turning barrel 500, and a turning rod 600.

[0033] The supporting blade 100 is arranged in a spiral shape. Multiple cross-section notches 110 are formed at intervals from bottom to top on the supporting blade 100, and all of the multiple cross-section notches 110 are formed by the downward settlement of the supporting blade 100. A conveyor belt 200 is arranged on the supporting blade 100 and forms a sinking inclined surface 210 at each cross-section notch 110. A driving device 300 is connected to the conveyor belt 200 to drive the conveyor belt 200 to rotate relative to the supporting blade 100. A drying device 400 is arranged above the supporting blade 100 and conveys hot air to the supporting blade 100. A material turning cylinder 500 is horizontally arranged at the cross-section notch 110 of the supporting blade 100, abuts against the sinking inclined surface 210 of the conveyor belt 200, and rotates under the drive of the conveyor belt 200. Generally, the material turning cylinder 500 may include a rotating cylinder 510 and a rotating shaft 520 arranged in the rotating cylinder 510. Multiple openings 515 are arranged on the rotating cylinder 510, and a spiral blade 530 is formed on the rotating shaft 520. Among them, the spiral direction of the spiral blade 530 is configured to push the raw material to move towards one end away from the axis of the supporting blade 100. A material turning rod 600 is horizontally arranged above the supporting blade 100 and there is a gap between the material turning rod 600 and the supporting blade 100. Among them, the material turning rod 600 rotates in the horizontal direction with one end close to the axis of the supporting blade 100 as the axis.

[0034] In the solution of this embodiment, by arranging the drying device 400 at the top of the supporting blade 100 and using the drying device 400 to convey hot air downward, the raw material can be fully dried during the upward transportation process, improving the drying effect. The spiral design of the supporting blade 100 not only saves the floor area of the equipment, but also increases the effective drying area of the conveyor belt 200, increases the maximum drying capacity of the equipment, and improves the drying efficiency of the raw material processing and drying equipment.

[0035] Furthermore, in the solution of this embodiment, by arranging multiple cross-section notches 110 at intervals on the supporting blade 100, multiple sinking inclined surfaces 210 are correspondingly formed when the conveyor belt 200 is attached to the supporting blade 100. During the process of the driving device 300 driving the conveyor belt 200 to rotate, the raw material transported on the conveyor belt 200 tumbles when passing through the sinking inclined surface 210, and the raw material is turned over, improving the drying efficiency and drying effect of the raw material processing and drying equipment. The arrangement of the multiple sinking inclined surfaces 210 enables the raw material to be turned over repeatedly during the drying process, further improving the drying efficiency.

[0036] As Figure 2 shown, the openings 515 are rectangular, and the multiple openings 515 are evenly arranged on the rotating cylinder 510. The length and width dimensions of the openings 515 are preferably set to be greater than or equal to the radius of the rotating cylinder 510 to facilitate the raw material to smoothly enter the interior of the rotating cylinder 510 through the openings 515.

[0037] In the solution of this embodiment, by setting up the material turning cylinder 500 and driving the material turning cylinder 500 to rotate by means of the conveyor belt 200, after the raw materials enter the inside of the rotating cylinder 510 through the opening 515 on the rotating cylinder 510, they are dispersed under the action of the spiral blade 530 and then fall onto the conveyor belt 200 through the opening 515 on the rotating cylinder 510, thus improving the drying efficiency.

[0038] In the solution of this embodiment, the spiral direction of the spiral blade 530 is configured to push the raw materials to move towards one end away from the axis of the support blade 100, so that after the raw materials enter the inside of the rotating cylinder 510, under the action of the spiral blade 530, they are dispersed in the direction away from the axis of the support blade 100, thus solving the problem that the raw materials accumulate on one side close to the axis of the support blade 100 when entering the support blade 100 from the feed rack 120, and further improving the drying effect.

[0039] In the solution of this embodiment, by setting up the material turning rod 600, when the raw materials pass through the material turning rod 600, they are spread out flat under the action of the material turning rod 600, thus improving the drying effect.

[0040] In some preferred embodiments, the distance between the material turning rod 600 and the support blade 100 can be set according to the maximum size of the raw materials, so that after the raw materials pass through the material turning rod 600, the larger-sized raw materials on the outer side of the conveyor belt 200 are spread out into a layer, and the smaller-sized raw materials on the inner side of the conveyor belt 200 have a certain accumulation, so that the drying time required for raw materials of different sizes is not much different, and further improving the overall drying effect of the raw material processing and drying equipment.

[0041] As Figure 3 shown, the bottom end of the support blade 100 can be connected with a feed rack 120, and the top end of the support blade 100 can be connected with a discharge rack 130. Both the feed rack 120 and the discharge rack 130 are horizontally arranged.

[0042] The horizontally arranged feed rack 120 and discharge rack 130 facilitate the placement and collection of raw materials.

[0043] In some preferred embodiments, a receiving bucket can also be arranged near the discharge rack 130. After the raw materials are dried, they freely fall into the receiving bucket from the high discharge rack 130, with a simple structure and convenient operation.

[0044] As Figure 3 shown, the conveyor belt 200 is connected end to end and is attached to the feed rack 120, the discharge rack 130, and the support blade 100, and rotates cyclically relative to the feed rack 120, the discharge rack 130, and the support blade 100, etc.

[0045] In the solution of this embodiment, generally, a tension roller group 820 may also be provided. The tension roller group 820 and the feeding rack 120, the discharging rack 130, the supporting blade 100, etc. jointly support and tension the conveyor belt 200, thereby ensuring the conveying effect of the conveyor belt 200.

[0046] The diameter of the spiral blade 530 gradually decreases from one end close to the axis of the supporting blade 100 to the other end.

[0047] In the solution of this embodiment, the diameter of the spiral blade 530 is set to gradually decrease from one end close to the axis of the supporting blade 100 to the other end. Under the action of the spiral blade 530, raw materials with larger volumes are more likely to spread in the direction away from the axis of the supporting blade 100, and raw materials with smaller volumes are more likely to approach the axis of the supporting blade 100. Raw materials of different sizes are generally separated, which is more convenient for drying the raw materials, and thus improves the drying quality.

[0048] A trigger rod 610 is further formed at one end of the material turning rod 600 close to the axis of the supporting blade 100. The trigger rod 610 abuts against the rotating shaft 520 to adjust the rotation speed of the rotating shaft 520.

[0049] In the solution of this embodiment, by providing the trigger rod 610, when the raw materials on the outer side of the conveyor belt 200 accumulate too much, the raw materials will push the material turning rod 600 to make the material turning rod 600 rotate, thereby driving the trigger rod 610 that abuts against the material turning rod 600 to apply pressure to the rotating shaft 520, reducing the rotation speed of the rotating shaft 520 and the speed of conveying raw materials to the outer side of the conveyor belt 200. After the problem of raw material accumulation on the outer side of the conveyor belt 200 is solved, the material turning rod 600 resets, the trigger rod 610 releases the pressure, and the rotation speed of the rotating shaft 520 resumes. The rotation speed of the rotating shaft 520 is adapted to the accumulation amount of raw materials on the conveyor belt 200, thereby ensuring the drying effect.

[0050] The material turning cylinder 500 generally may further include: a limiting plate 511, at least one sliding rod 513, and at least one friction wheel 540.

[0051] The limiting plate 511 is arranged on the inner wall of one end of the rotary drum 510 close to the axis of the supporting blade 100. The inner wall of the rotary drum 510 is provided with a first annular inclined surface 512, and the first annular inclined surface 512 is located at one end of the limiting plate 511 close to the axis of the supporting blade 100. The first annular inclined surface 512 gradually approaches the axis of the rotary drum 510 starting from the limiting plate 511. The outer wall of the rotating shaft 520 forms a second annular inclined surface 521 at one end close to the axis of the supporting blade 100, and the second annular inclined surface 521 is parallel to the first annular inclined surface 512. At least one slide bar 513 extends outward from the limiting plate 511, and at least one slide bar 513 is parallel to the first annular inclined surface 512. At least one friction wheel 540 is sleeved on at least one slide bar 513 and is rotatably connected to the first annular inclined surface 512 and the second annular inclined surface 521.

[0052] As Figure 7 shown, the inner wall of the rotary drum 510 extends outward from the limiting plate 511 to form a first annular inclined surface 512, and the first annular inclined surface 512 gradually approaches the axis of the rotary drum 510 starting from the limiting plate 511.

[0053] In the solution of this embodiment, by arranging the first annular inclined surface 512 on the inner wall of the rotary drum 510, arranging the parallel second annular inclined surface 521 on the outer wall of the rotating shaft 520, and arranging the rotatably connected friction wheel 540 between the two, when the rotary drum 510 rotates, it can drive the friction wheel 540 to rotate, and further drive the rotating shaft 520 to rotate.

[0054] In the solution of this embodiment, the rotary drum 510 rotates driven by the conveyor belt 200, the rotation speed of the conveyor belt 200 remains unchanged, and the rotation speed of the rotary drum 510 remains unchanged. In some preferred embodiments, the rotary drum 510 can be meshed with the conveyor belt 200 to achieve transmission.

[0055] The tipping drum 500 generally may further include: a baffle 514, an adjusting disk 550, at least one adjusting column 551, a first compression spring 560, and at least one second compression spring 570.

[0056] The baffle 514 is sleeved on the rotating shaft 520 and is connected to the slide bar 513. The adjusting disk 550 is sleeved on the rotating shaft 520 and abuts against the trigger rod 610. At least one adjusting column 551 is arranged at one end of the adjusting disk 550 close to the inside of the rotary drum 510; one end of at least one adjusting column 551 is connected to the end face of the adjusting disk 550, and the other end passes over the baffle 514 and contacts at least one friction wheel 540. The first compression spring 560 is arranged between the baffle 514 and the adjusting disk 550, and its two ends respectively abut against the baffle 514 and the adjusting disk 550. At least one second compression spring 570 is arranged between the limiting plate 511 and at least one friction wheel 540, and its two ends respectively abut against the limiting plate 511 and at least one friction wheel 540.

[0057] By providing the baffle 514 , the maximum moving position of the friction wheel 540 is limited to prevent the friction wheel 540 from falling off the slide bar 513 .

[0058] Due to the special setting of the first annular bevel 512 and the second annular bevel 521, when the friction wheel 540 is close to the ends of the drum 510 and the shaft 520, the radius of the position on the second annular bevel 521 that contacts the friction wheel 540 is smaller. As the friction wheel 540 gradually goes deeper into the drum 510, the radius of the position on the second annular bevel 521 that contacts the friction wheel 540 gradually increases.

[0059] The radius of the second annular slope 521 is R 1 , friction wheel 540 radius R 2 The radius of the first annular slope 512 is approximately equal to R 1 +2R 2 The drum 510 rotates one circle, and the position on the first annular inclined surface 512 that contacts the friction wheel 540 rotates one circle. The running distance is 2π (R 1 +2R 2 ), the rotation of the drum 510 is transmitted to the shaft 520 through the friction wheel 540, and the number of revolutions of the shaft 520 is 2π (R 1 +2R 2 ) / 2πR 1 =(R 1 +2R 2 ) / R 1 . R 2 is a constant value, as R 1 The more the rotation of the rotating shaft 520 increases, the smaller the number of rotations of the rotating shaft 520. That is, as the friction wheel 540 gradually penetrates into the inside of the rotating drum 510 under the extrusion of the adjusting column 551, the rotation speed of the rotating shaft 520 gradually decreases.

[0060] By providing an adjustment disk 550 that contacts the trigger rod 610 and an adjustment column 551 that contacts the friction wheel 540, when the raw materials on the outside of the conveyor belt 200 are excessively accumulated, the raw materials push the material turning rod 600 to rotate, driving the trigger rod 610 to squeeze the adjustment disk 550. The adjustment disk 550 moves toward the inside of the rotating drum 510, thereby driving the adjustment column 551 to squeeze the friction wheel 540, causing the friction wheel 540 to penetrate into the inside of the rotating drum 510, thereby reducing the rotation speed of the rotating shaft 520. The rotation speed of the rotating shaft 520 is reduced, and the efficiency of the spiral blade 530 in conveying raw materials to the outside of the conveyor belt 200 is reduced, thereby preventing more raw materials from being conveyed to the outside of the conveyor belt 200, and reducing the risk of accumulation on the outside of the conveyor belt 200.

[0061] By setting the first compression spring 560, after the problem of raw material accumulation on the outer side of the conveyor belt 200 is solved, that is, after the thrust applied by the raw materials to the turning rod 600 disappears, the adjusting disc 550 pushes the trigger rod 610 to rotate under the elastic force of the first compression spring 560, thereby driving the turning rod 600 to reset.

[0062] By setting the second compression spring 570, after the adjusting disc 550 is reset under the elastic force of the first compression spring 560, the friction wheel 540 returns to a position close to the end of the turning cylinder 500 under the elastic force of the second compression spring 570, and the rotation speed of the rotating shaft 520 increases.

[0063] In the solution of this embodiment, according to the magnitude of the accumulation amount of the raw materials on the outer side of the conveyor belt 200 at the turning rod 600, the thrust received by the turning rod 600 is different, and the pressure applied by the trigger rod 610 to the adjusting disc 550 is different, so that the distance that the friction wheel 540 penetrates into the rotating cylinder 510 is different. The rotation speed of the rotating shaft 520 is adapted to the accumulation amount at the turning rod 600, the self-adjustment effect of the raw material processing and drying equipment is improved, and the drying effect of the raw material processing and drying equipment is enhanced.

[0064] In some preferred embodiments, a plurality of sliding rods 513 may be provided at intervals on the limiting plate 511, and a friction wheel 540 is correspondingly sleeved on each sliding rod 513, and the plurality of friction wheels 540 are jointly driven, so as to improve the transmission effect from the rotating cylinder 510 to the rotating shaft 520. A plurality of adjusting columns 551 may be correspondingly provided on the adjusting disc 550, and the plurality of adjusting columns 551 correspond to the plurality of friction wheels 540 one by one, so as to ensure the structural stability of the adjusting disc 550 while ensuring the adjusting effect of the adjusting disc 550.

[0065] The driving device 300 generally may include: a motor 310 and a transmission rod 320. The transmission rod 320 is connected to the motor 310, and a plurality of transmission discs 330 are provided on the transmission rod 320, and the plurality of transmission discs 330 are all docked with the conveyor belt 200.

[0066] In the solution of this embodiment, by setting the motor 310 and the transmission rod 320 connected to the motor 310, and using the plurality of transmission discs on the transmission rod 320 to dock with the conveyor belt 200, the power is transmitted in multiple directions, ensuring the rotation effect of the conveyor belt 200.

[0067] The raw material processing and drying equipment generally may further include: a support frame 700 and a limiting cylinder 800.

[0068] The support frame 700 is arranged on the periphery of the support blade 100 and is connected to the support blade 100. The limiting cylinder 800 is arranged inside the support blade 100 and is connected to the support blade 100.

[0069] The solution of this embodiment improves the overall structural stability of the raw material processing and drying equipment by providing a support frame 700 and a limiting cylinder 800.

[0070] like Figure 6 As shown, one end of the turning cylinder 500 close to the limiting cylinder 800 passes through the limiting cylinder 800 .

[0071] A positioning block 830 is provided inside the limiting cylinder 800, and a vertical positioning rod 831 is provided on the positioning block 830. A clearance opening 840 is formed in the limiting cylinder 800 in the area corresponding to the positioning rod 831, and the material turning rod 600 passes through the clearance opening 840. One end of the material turning rod 600 connected to the trigger rod 610 is rotatably sleeved on the positioning rod 831, and the trigger rod 610 presses against the adjustment disk 550 located inside the limiting cylinder 800.

[0072] In some preferred embodiments, mesh grids or enclosures may be provided on both the inner and outer sides of the supporting blade 100 to prevent the raw materials from slipping off the conveyor belt 200 during the drying process.

[0073] The limiting cylinder 800 is provided with a rotating wheel 810 at each section notch 110 , and each rotating wheel 810 supports the conveyor belt 200 .

[0074] In the solution of this embodiment, a rotating wheel 810 is provided at each cross-sectional notch 110 , and the rotating wheel 810 is used to support the conveyor belt 200 , so that the conveyor belt 200 is tensioned, thereby ensuring the conveying effect of the conveyor belt 200 .

[0075] In some preferred embodiments, the rotating wheel 810 can be engaged with the conveyor belt 200 and rotate along with the rotation of the conveyor belt 200 , thereby improving the running smoothness of the conveyor belt 200 .

[0076] In the scheme of this embodiment, the raw material processing and drying equipment can generally also include an outer shell (not shown in the figure, so as to better show the internal structure of the raw material processing and drying equipment), and the outer shell covers the entire supporting blade 100 and the limiting cylinder 800 and other structures to increase the temperature around the supporting blade 100 and ensure the drying effect.

[0077] In some embodiments, the drying device 400 can be directly mounted on the limiting cylinder 800. In other embodiments, the drying device 400 can be mounted on the housing or the support frame 700.

[0078] The specific working process of the raw material processing and drying equipment provided by the present invention is described in combination with the above embodiments:

[0079] The motor 310 starts, driving the conveyor belt 200 to rotate. At the same time, the drying device 400 outputs hot air. The conveyor belt 200 drives the raw materials to enter the support blades 100 from the feeding rack 120 and gradually move upward along the spiral direction of the support blades 100. After the raw materials move a certain distance, they reach the cross-section notch 110, roll and slide down along the sinking inclined plane 210 of the conveyor belt 200, and arrive at the turning barrel 500. When the raw materials pass through the turning barrel 500, they are dispersed under the thrust of the spiral blades 530 on the rotating shaft 520. Among them, the raw materials with larger sizes are pushed to the outside of the conveyor belt 200 (i.e., the side away from the axis of the support blades 100). After the raw materials pass through the turning barrel 500, they move to the turning rod 600 and are spread out under the action of the turning rod 600. The raw materials continue to move and, before moving to the discharging rack 130, successively pass through multiple cross-section notches 110, turning barrels 500, and turning rods 600, repeatedly turning over and spreading out.

[0080] When the raw materials pass through the turning barrel 500 and the turning rod 600, when the raw materials at the turning rod 600 accumulate, the turning rod 600 rotates under the push of the raw materials, driving the trigger rod 610 to press against the adjustment disc 550 of the turning barrel 500. The adjustment disc 550 moves under the extrusion of the trigger rod 610, driving the adjustment column 551 to squeeze the friction wheel 540, causing the friction wheel 540 to move towards the inside of the turning barrel 500, thereby reducing the rotation speed of the rotating shaft 520. The more the materials accumulate at the turning rod 600, the smaller the rotation speed of the rotating shaft 520. After the accumulation situation of the raw materials at the turning rod 600 is solved, under the elastic force of the first compression spring 560 and the second compression spring 570, the friction wheel 540, adjustment disc 550, adjustment column 551, trigger rod 610, and turning rod 600, etc. reset, and the rotation speed of the rotating shaft 520 is restored.

[0081] The technical features of the above embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combinations of these technical features do not conflict, they should all be considered as the scope described in this specification.

[0082] The above-described embodiments only represent several implementation manners of the present invention. Their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
