Therefore, a fresh leaf conveyor in a indigo leaf production line is proposed to solve the above-mentioned problems. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a fresh leaf conveyor in a bamboo leaf production line in view of the deficiencies in the above-mentioned prior art.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is: a fresh leaf conveyor in a reed leaf production line, comprising two electric rollers, support legs are arranged on the front and rear sides of the electric rollers, the external transmission of the two electric rollers is connected with a conveyor belt, the conveyor belt is driven to rotate by the rotation of the electric rollers, a drainage hole is opened through the surface of the conveyor belt, enclosures are arranged on the front and rear sides of the conveyor belt, two electric fans are arranged on the top of the enclosure through a bracket, the reed leaves on the conveyor belt are blown by the electric fans, and the air drying and dehydration speed is increased, a washing pool is arranged on the left side of the conveyor belt, an oven is arranged on the right side of the conveyor belt, a pull-out drying drawer is arranged in the oven, and a shovel turning mechanism is arranged above the conveyor belt;

[0007] The shoveling mechanism comprises an annular slide groove, two first sliding blocks, a transmission shaft, and a pulley;

[0008] The annular slide is opened on the front side of the enclosure at the back side, and the annular slide is set in a "U" shape. The first sliding block is slidably connected to the inside of the annular slide. A shovel plate is fixedly connected to the front side of the first sliding block, and the shovel plate is set in a trapezoidal strip shape. The shovel plate is set to shovel up the indigo leaves adhering to the surface of the conveyor belt, thereby improving the air-drying efficiency of the moisture at the bottom of the indigo leaves. The front side of the enclosure at the back side is rotatably connected to a transmission shaft, and the front end of the transmission shaft is connected to the front end of the electric roller on the left side through a pulley transmission. The rotation of the electric roller drives the transmission shaft to rotate through the pulley. The middle part of the transmission shaft is fixedly connected to a fixed block, and telescopic rods are fixedly connected to the upper and lower sides of the fixed block. The opposite ends of the two telescopic rods are respectively hinged to the front ends of the two shovel plates.

[0009] Preferably, a cleaning mechanism is provided above the shovel plate, and the cleaning mechanism includes a transmission tooth, which is fixedly connected to the top of the first sliding block, and the front side of the enclosure on the back side is rotatably connected to a first horizontal axis through a bearing, and three scrapers are fixedly connected to the first horizontal axis, and the scrapers are in contact with the upper surface of the shovel plate, and a first gear is fixedly connected to the first horizontal axis, and the first gear is meshed with the transmission tooth, and the scraper is driven to rotate through the first horizontal axis to scrape the reed leaves on the shovel plate from a high place. When the reed leaves are thrown from a high place, the reed leaves in motion are in more complete contact with the flowing air, thereby accelerating the evaporation rate of water.

[0010] Preferably, a second horizontal shaft is provided on the right side of the first horizontal shaft. The rear end of the second horizontal shaft is rotatably connected to the front surface of the enclosure on the back. A water-absorbing sponge is fixedly connected to the middle of the second horizontal shaft. The water-absorbing sponge is arranged in a circular column shape. The water-absorbing sponge contacts the upper surface of the scraper. A second gear is fixedly connected to the middle of the second horizontal shaft. The second gear is arranged behind the water-absorbing sponge. The second gear meshes with the transmission teeth. The water-absorbing sponge is driven to rotate by the second horizontal shaft, and the water droplets remaining on the surface of the shovel plate are sucked off, so as to prevent the bamboo leaves from being adsorbed on the surface of the shovel plate due to surface tension, making it easier for the scraper to shovel the bamboo leaves from the shovel plate.

[0011] Preferably, bristles are arranged on the surface of the water-absorbing sponge. The impurities on the surface of the shovel plate are swept off by the bristles. The scraper contacts the bristles. When the scraper rotates, the impurities mixed in the bristles can be knocked off, so as to keep the cleanliness of the bristles.

[0012] Preferably, a draining mechanism is arranged between the two shovel plates. The draining mechanism includes two sliding rods. The rear ends of the sliding rods slide through the enclosure on the back through linear bearings. The front ends of the sliding rods are fixedly connected with draining inclined plates. After the bamboo leaves are shoveled off the top shovel plate by the scraper, they will fall on the draining inclined plates, and the water on the surface is drained through the draining grooves on the draining inclined plates.

[0013] Preferably, a bidirectional spiral slide rail is arranged on the surface of the transmission shaft. A ball is slidably connected inside the bidirectional spiral slide rail. The top of the ball is fixedly connected with the draining inclined plate through a connecting rod. The bidirectional spiral slide rail is driven to rotate by the rotation of the transmission shaft, and the draining inclined plate is driven to move back and forth through the ball and the connecting rod, and the bamboo leaves on the draining inclined plate are shaken, so that the water on the surface of the bamboo leaves is more likely to break away from the surface of the bamboo leaves under the shaking.

[0014] Preferably, a second chute is opened on the front surface of the enclosure on the back. A second slider is slidably connected inside the second chute. One end of a spring is fixedly connected to the top of the second slider. The top end of the spring is fixedly connected to the inner wall of the top of the second chute.

[0015] Preferably, a third gear is fixedly connected to the middle of the transmission shaft. A rack is fixedly connected to the front surface of the second slider. The rack meshes with the third gear. A pressing plate is fixedly connected to the front surface of the rack. The pressing plate is arranged above the draining inclined plate. The bamboo leaves on the draining inclined plate are squeezed and dehydrated by the downward pressure of the pressing plate.

[0016] The present invention adopts the above technical solutions and can bring the following beneficial effects:

[0017] 1. The invention sets up a turning shovel mechanism. The electric roller rotates and drives the transmission shaft through a pulley, enabling the fixed block and the telescopic rod to drive the shovel plate to move in a "return" shape within the annular sliding groove. The shovel plate shovels up the bamboo leaves that are attached to the conveyor belt and brings them into the air to be blown by a fan, increasing the contact area between the bamboo leaves and the air, accelerating the dehydration efficiency of the moisture at the bottom of the bamboo leaves, reducing the baking time of the bamboo leaves during oven drying processing, reducing the energy consumption of the oven, and improving the processing efficiency.

[0018] 2. The invention sets up a cleaning mechanism. The shovel plate drives the first slider to move, and the transmission teeth mesh with the first gear, causing the first horizontal shaft to drive the scraper to rotate. The scraper scrapes off the bamboo leaves on the shovel plate at a high position, and the bamboo leaves are in full contact with the flowing air during the falling process, further accelerating the dehydration speed. On the basis of the turning shovel mechanism improving the dehydration efficiency, the bamboo leaves are dried again, strengthening the dehydration effect.

[0019] 3. The invention cooperates the cleaning mechanism with the water-absorbing sponge. The first slider moves to drive the second gear to rotate, causing the second horizontal shaft to drive the water-absorbing sponge to rotate. The water-absorbing sponge can absorb the residual water droplets on the surface of the shovel plate, preventing the bamboo leaves from adhering to the shovel plate due to surface tension of water, making it easier for the scraper to shovel off the bamboo leaves, ensuring the normal operation of the cleaning mechanism, ensuring that the bamboo leaves can be smoothly shoveled off for further drying, and maintaining the high-efficiency operation of the equipment. At the same time, the bristles on the surface of the water-absorbing sponge can sweep off the impurities on the shovel plate, and the scraper can also flick off the impurities on the bristles, maintaining the cleanliness of the bristles, thereby ensuring the stable functions of the water-absorbing sponge in absorbing water and cleaning impurities, and assisting the dehydration and cleaning of the bamboo leaves from the side.

[0020] 4. The invention sets up a shaking and draining mechanism. The transmission shaft rotates to drive the bidirectional spiral slide rail, and through the balls and connecting rods, the draining inclined plate moves back and forth to shake the bamboo leaves that fall on it, accelerating the separation of water. At the same time, the transmission shaft drives the third gear to rotate, which meshes with the rack to press down the pressing plate to squeeze and dehydrate the bamboo leaves on the draining inclined plate. On the basis of the turning shovel mechanism and the cleaning mechanism improving the dehydration efficiency, the bamboo leaves are further dehydrated from two aspects of shaking and squeezing, significantly enhancing the dehydration effect, improving the drying degree of the bamboo leaves before entering the oven, reducing the energy consumption of the oven, and improving the processing efficiency.

Specific embodiments

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Please refer to Figures 1-8 , an embodiment of the present invention is: A fresh leaf conveyor in a bamboo leaf production line includes two electric rollers 2. Support legs 1 are arranged on the front and rear sides of the electric rollers 2. A conveyor belt 3 is externally connected to the two electric rollers 2 in a transmission manner. The conveyor belt 3 is rotated by the rotation of the electric rollers 2. Drainage holes are formed through the surface of the conveyor belt 3. Enclosures 6 are arranged on the front and rear sides of the conveyor belt 3. Two electric fans 601 are arranged on the top of the enclosures 6 through brackets. By arranging the electric fans 601, the bamboo leaves on the conveyor belt 3 are blown, and the air-drying and dehydration speed is increased. A cleaning tank 4 is arranged on the left side of the conveyor belt 3. An oven 5 is arranged on the right side of the conveyor belt 3. A pull-out baking drawer 501 is arranged in the oven 5. A turning shovel mechanism 7 is arranged above the conveyor belt 3;

[0032] The shoveling mechanism 7 includes an annular slide groove 701, two first sliding blocks 702, a transmission shaft 704, and a pulley 705;

[0033] The annular slide 701 is opened on the front side of the back enclosure 6, and the annular slide 701 is set in a "U" shape. The first sliding block 702 is slidably connected to the inside of the annular slide 701. The front side of the first sliding block 702 is fixedly connected with a shovel plate 703, and the shovel plate 703 is set in a trapezoidal strip shape. The shovel plate 703 is set to shovel the indigo leaves adhering to the surface of the conveyor belt 3, so as to improve the air-drying efficiency of the moisture at the bottom of the indigo leaves. The front side of the back enclosure 6 is rotatably connected with a transmission shaft 704, and the front end of the transmission shaft 704 is connected to the front end of the left electric roller 2 through a pulley 705. The rotation of the electric roller 2 drives the transmission shaft 704 to rotate through the pulley 705. The middle part of the transmission shaft 704 is fixedly connected with a fixed block 706, and the upper and lower sides of the fixed block 706 are fixedly connected with telescopic rods 707, and the opposite ends of the two telescopic rods 707 are respectively hinged to the front ends of the two shovel plates 703.

[0034] Working principle: First, let the staff place the cleaned indigo leaves in the cleaning pool 4 on the conveyor belt 3, then turn on the electric roller 2 to rotate clockwise to drive the conveyor belt 3 to rotate, and transport the indigo leaves to the right to the drying drawer 501 on the oven 5. During the transportation process, the electric fan 601 blows air to dry the water on the surface of the indigo leaves. During the transportation process, the electric roller 2 rotates and drives the transmission shaft 704 to rotate through the pulley 705. The rotation of the transmission shaft 704 drives the fixed block 706 to rotate. The rotation of the fixed block 706 drives the two shovel plates 703 to rotate through the telescopic rod 707. The shovel plates 703 move in a "return" shape under the limiting action of the first slider 702 and the annular slide 701. During the movement, the indigo leaves attached to the surface of the conveyor belt 3 are shoveled down, and brought into the air with the shovel plates 703 to receive the blowing of the electric fan 601, thereby improving the air drying efficiency of the surface of the indigo leaves.

[0035] See also Figures 1-8 On the basis of the above-mentioned embodiment, in another embodiment of the present invention, a cleaning mechanism 8 is arranged above the shovel plate 703, and the cleaning mechanism 8 includes a transmission tooth 801, and the transmission tooth 801 is fixedly connected to the top of the first sliding block 702. The front of the back enclosure 6 is rotatably connected to the first horizontal axis 802 through a bearing, and three scrapers 803 are fixedly connected to the first horizontal axis 802. The scrapers 803 are in contact with the upper surface of the shovel plate 703, and the first gear 804 is fixedly connected to the first horizontal axis 802. The first gear 804 is meshed with the transmission tooth 801, and the scrapers 803 are driven to rotate through the first horizontal axis 802, and the indigo leaves on the shovel plate 703 are scraped off from a high place. When the indigo leaves are thrown down from a high place, the indigo leaves in motion are in more complete contact with the flowing air, thereby accelerating the evaporation rate of water.

[0036] A second transverse axis 805 is arranged on the right side of the first transverse axis 802, and the rear end of the second transverse axis 805 is rotatably connected to the front side of the back enclosure 6, and a water-absorbing sponge 806 is fixedly connected to the middle part of the second transverse axis 805. The water-absorbing sponge 806 is arranged in a circular columnar shape, and the water-absorbing sponge 806 contacts the upper surface of the scraper 803. A second gear 807 is fixedly connected to the middle part of the second transverse axis 805, and the second gear 807 is arranged behind the water-absorbing sponge 806. The second gear 807 is meshed with the transmission tooth 801, and the water-absorbing sponge 806 is driven to rotate through the second transverse axis 805, and the water droplets remaining on the surface of the shovel board 703 are absorbed, thereby preventing the reed leaves from being adsorbed on the surface of the shovel board 703 due to the water surface tension, making it easier for the scraper 803 to shovel the reed leaves off the shovel board 703.

[0037] The surface of the absorbent sponge 806 is provided with bristles, and the impurities on the surface of the shovel plate 703 are swept away by the bristles. The scraper 803 contacts the bristles, and the scraper 803 can remove the impurities mixed on the bristles while rotating, thereby maintaining the cleanliness of the bristles.

[0038] Working principle: During the movement of the shovel plate 703 and the first slider 702, the first gear 804 is driven to rotate through the transmission tooth 801, and the rotation of the first gear 804 drives the first horizontal axis 802 and the scraper 803 to rotate, and the reed leaves on the shovel plate 703 are scraped down from a high place by the rotating scraper 803. When the reed leaves are thrown from a high place, the reed leaves in motion are in more complete contact with the flowing air, which accelerates the evaporation rate of water. While the scraper 803 rotates, it can remove impurities mixed in the bristles, thereby maintaining the cleanliness of the bristles. As the first slider 702 continues to move, the second gear 807 and the second horizontal axis 805 are driven to rotate, and the absorbent sponge 806 and the bristles are driven to rotate. The absorbent sponge 806 absorbs the water droplets remaining on the surface of the shovel plate 703, thereby preventing the reed leaves from being adsorbed on the surface of the shovel plate 703 due to the water surface tension, making it easier for the scraper 803 to shovel the reed leaves off the shovel plate 703, and the impurities on the surface of the shovel plate 703 are swept away by the bristles.

[0039] See also Figures 1-8 On the basis of the above-mentioned embodiment, in another embodiment of the present invention, a shaking mechanism 9 is arranged between the two shovel plates 703, and the shaking mechanism 9 includes two slide bars 901. The rear end of the slide bar 901 slides through the back enclosure 6 through a linear bearing, and the front end of the slide bar 901 is fixedly connected with a drain inclined plate 902. After the indigo leaves are scraped off the top shovel plate 703 by the scraper 803, they will fall on the drain inclined plate 902, and the surface moisture will be drained through the drain groove on the drain inclined plate 902.

[0040] A bidirectional spiral slide 903 is provided on the surface of the transmission shaft 704, and a ball 904 is slidably connected inside the bidirectional spiral slide 903. The top of the ball 904 is fixedly connected to the drain inclined plate 902 through a connecting rod. The rotation of the transmission shaft 704 drives the bidirectional spiral slide 903 to rotate, and the ball 904 and the connecting rod drive the drain inclined plate 902 to move back and forth, and shake the indigo leaves on the drain inclined plate 902, so that the water on the surface of the indigo leaves will be easier to separate from the surface of the indigo leaves under the shaking.

[0041] A second slide groove 905 is provided on the front side of the back enclosure 6, and a second slider 906 is slidably connected inside the second slide groove 905. One end of a spring 907 is fixedly connected to the top of the second slider 906, and the top of the spring 907 is fixedly connected to the top inner wall of the second slide groove 905.

[0042] A third gear 9010 is fixedly connected to the middle of the transmission shaft 704, a rack 908 is fixedly connected to the front of the second slider 906, the rack 908 is meshed with the third gear 9010, a pressure plate 909 is fixedly connected to the front of the rack 908, and the pressure plate 909 is arranged above the drain inclined plate 902. The pressure plate 909 is pressed down to squeeze and dehydrate the indigo leaves on the drain inclined plate 902.

[0043] Working principle: The transmission shaft 704 drives the bidirectional spiral guide rail 903 to rotate during its rotation, and drives the drain inclined plate 902 to move forward and backward through the ball 904 and the connecting rod, and shakes the indigo leaves on the drain inclined plate 902, so that the water on the surface of the indigo leaves can more easily leave the surface of the indigo leaves under the shaking. The transmission shaft 704 drives the third gear 9010 to rotate while the third gear 9010 rotates. The first half of the rotation of the third gear 9010 engages with the rack 908 and drives the pressure plate 909 to move downward, and the indigo leaves on the drain inclined plate 902 are squeezed and dehydrated by pressing down the pressure plate 909.

[0044] The present invention provides a fresh leaf conveyor in a production line of indigo leaves. There are many methods and ways to implement the technical solution. The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention.
