Description

[0002] Chestnuts are usually picked in September and October. Since chestnut trees are tall, the chestnut fruits are usually knocked to the ground before being picked. During the picking process, some dirt, leaves and other debris will adhere to the outer surface of the chestnuts, so the chestnuts need to be cleaned after the harvest.

[0003] The existing chestnut cleaning machine structure basically adopts a flowing water cleaning method, which disturbs the water flow to cause the chestnuts on the conveying chain plate to flip irregularly, and is cleaned in conjunction with a cleaning roller brush. However, the existing cleaning device, due to the chain plate transmission method, causes the mud or impurities that fall off from the upper conveying chain plate to move downward with gravity, and the lower conveying chain plate does not have an upper roller brush, resulting in mud adhering to the inner side of the lower conveying chain plate, and the mud eventually falls to the bottom of the cleaning equipment during the cleaning process.

[0047] A sludge cleaning mechanism is provided at the bottom of the inner side of the cleaning box 1.

The sludge cleaning mechanism is displaced by the rotation of the conveying chain plate 7 to clean the sludge at the bottom of the inner side of the cleaning box 1.

The levers 24 correspond to the sliding columns 32. A second guide groove 19 corresponding to the third slider 37 is provided at the position of the inner wall of the cleaning box 1. The second guide groove 19 is an oblique structure. The input end and the output end of the two adjacent groups of second guide grooves 19 are in a superimposed state in the vertical direction. When the lever 24 follows the displacement of the conveying chain plate 7, the third slider 37 at the bottom of the sliding column 32 is pushed to displace inside the second guide groove 19. The sliding column 32 at the top of the third slider 37 is driven to displace downward by the guiding effect of the second guide groove 19. The sludge scraper 16 and the supporting longitudinal rod 31 are hinged to each other, and a torsion spring is provided between the two ends of the sludge scraper 16 and the supporting longitudinal rod 31.

[0048] A material guide plate 11 is provided at the output end of the cleaning box 1, a lower hopper 9 is provided at the input end of the cleaning box 1, a wind selection mechanism 12 is provided on one side of the bottom of the lower hopper 9, and a discharge port 13 corresponding to the wind selection mechanism 12 is provided on the other side of the bottom of the lower hopper 9. A sewage discharge port 2 is provided at the end of the bottom of the cleaning box 1 away from the support frame 3, and a sewage discharge through hole 14 connected with the sewage discharge port 2 is provided inside the cleaning box 1. Several groups of cleaning roller brushes 8 are evenly distributed on the top of the inner side of the cleaning box 1, and the cleaning roller brushes 8 are synchronously connected to a driving unit.

[0049] The use process of the chestnut processing cleaning device proposed in this embodiment is as follows: when the chestnut cleaning device is in operation, the driving motor 10 and the air selection mechanism 12 are turned on respectively, and the air selection mechanism 12 generates wind force to screen the chestnuts added through the lower hopper 9, so that light impurities such as branches and leaves mixed in the chestnuts are discharged from the position of the discharge port 13 under the action of the wind screen, and the chestnuts enter the interior of the cleaning box 1 through the bottom of the lower hopper 9. At this time, water for cleaning is added to the interior of the cleaning box 1;

[0050] The cleaning roller brush 8 is driven to rotate by an external driving unit, and at this time, the driving motor 10 drives the transmission mechanism 5 at both ends of the main transmission shaft 4 to rotate, thereby driving the main transmission roller 6 to rotate, and then driving the transmission chain plate 7 to follow the rotation through the main transmission roller 6, and then the chestnuts on the top are transmitted through the transmission chain plate 7. While the transmission chain plate 7 is running, the lower steering roller 15 and the upper steering roller 23 are driven to follow the rotation, and the main transmission roller 6, the lower steering roller 15 and the upper steering roller 23 have the same running direction;

[0051] The upper steering roller 23 is rotated to drive the mounting shaft 29 connected thereto to rotate, thereby driving the cam 28 to rotate. The rotation of the cam 28 pushes the two ends of the support cross bar 26, so that the support cross bar 26 moves upward. When the support cross bar 26 moves upward, it pushes the fourth slider 40 above it to drive the bristle brush 38 to move upward. At this time, the fourth slider 40 is guided by the first guide groove 18 and moves in an obliquely upward direction, so that the bristles on the top of the bristle brush 38 push the chestnut on the top of the conveying chain plate 7, so that the chestnut is displaced and flipped.

[0052] During the upward displacement of the support cross bar 26, the fourth guide groove 46 limits the first slider 27, so that the support cross bar 26 is displaced vertically.

[0053] As the bristle brush 38 moves upward, the supporting connecting rod 42 pulls the piston plate 44 to move upward. At this time, the one-way folding plates 43 at both ends of the piston plate 44 are affected by the water flow and then fold downward, so that the water flows through the upper end of the piston cavity 39 and enters the interior of the piston cavity 39;

[0054] When the cam 28 continues to rotate and no longer generates an upward thrust on the supporting cross bar 26, the first spring 25 and the third spring 41 rebound and drive the bristle brush 38 and the piston plate 44 to reset downward. At this time, the piston plate 44 drives the one-way folding plate 43 to follow the displacement, and the one-way folding plate 43 is also affected by the water flow in the opposite direction, so that the one-way folding plate 43 is folded in the opposite direction and is in a horizontal state with the piston plate 44, and then cooperates with the piston plate 44 to squeeze the water flow inside the piston cavity 39 and discharge it from the position of the nozzle 45. The water flow discharged by the nozzle 45 cleans the two ends of the top of the sludge baffle 21, thereby realizing the directional sewage discharge function of the precipitated impurities generated after the chestnuts are washed;

[0055] Furthermore, as the transmission chain plate 7 rotates, the lever 24 is driven to rotate accordingly. When the lever 24 is displaced to fit the sliding column 32, the sliding column 32 is horizontally displaced by the driving force of the lever 24, and the third slider 37 at the bottom of the sliding column 32 is displaced accordingly. However, the third slider 37 is guided by the second guide groove 19, driving the sliding column 32 to continuously descend while horizontally displacing.

[0056] The displacement of the third slider 37 drives the limit column 34 in the inner sleeve of the support ring 33 to move, and the limit column 34 drives the support longitudinal rod 31 and the connecting rod 22 connected to the second slider 35 to move, and the displacement of the support longitudinal rod 31 drives the sludge scraper 16 to follow the displacement to push and clean the precipitated impurities at the bottom of the cleaning box 1, and the displacement of the connecting rod 22 continuously compresses the second spring 36;

[0057] When the sliding column 32 follows and continues to descend until it is separated from the lever 24, the second spring 36 drives the connecting rod 22, the second slider 35, the supporting longitudinal rod 31, and the silt scraper 16 to reset in the opposite direction. During the process of the silt scraper 16 resetting in the opposite direction, the water flow blocks the back of the silt scraper 16, so that the silt scraper 16 generates an upward turning force, thereby generating a torsion force on the torsion springs at both ends. When the silt scraper 16 is completely reset, under the action of the torsion spring, the bottom of the silt scraper 16 fits with the bottom of the cleaning box 1 again;

[0058] The sliding column 32 and the third slider 37 follow the reset synchronously. During the displacement of the sludge scraper 16, the vertical overlapping area of ​​the two adjacent groups of second guide grooves 19 is set, so that the displacement distance of the two adjacent groups of sludge scrapers 16 has a front-to-back overlapping area, so that the sludge scraper 16 of the previous group can further push the precipitated impurities pushed by the latter group of sludge scrapers 16 after resetting, realizing the structural design of relay push, and then through the reciprocating push of multiple groups of sludge scrapers 16, the precipitated impurities are pushed to the position of the sewage discharge through hole 14, and further discharged in a direction through the sewage discharge port 2, and through the cooperation of various components, the cleaning function of the chestnuts inside the cleaning box 1 is realized. At the same time, the directional cleaning of sludge and impurities is also realized, thereby reducing the difficulty of later cleaning and improving the practicability of the equipment.

[0059] The specific implementation methods of this embodiment are described above, but this embodiment is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Ordinary technicians in this field can also make many forms inspired by this embodiment, all of which are within the protection of this embodiment.
