Technical Field
[0001] This utility model relates to the field of chestnut processing technology, and in particular to an integrated machine for removing and cleaning chestnut burrs. Background Technology
[0002] Chestnut is a deciduous tree belonging to the genus *Castanopsis* in the family Fagaceae. Its stems and branches are relatively thick and cylindrical. The surface is dark green with fine longitudinal stripes and small hairs. The leaves are mostly curled with short petioles. The leaf blades are elliptical and yellowish-brown in color. Young leaves are covered with fine hairs. The flowers are small and pale yellow with yellow stigmas. The flowering period is from May to June, and the fruiting period is from July to August.
[0003] The existing patents only allow chestnuts to be shelled first in a shelling machine, and then the shelled chestnuts to be washed in a cleaning device to obtain clean chestnuts. This process involves multiple machines, which increases the number of steps and the labor costs, thus affecting the overall production cost and efficiency. Utility Model Content
[0004] In order to overcome the existing problem of not being able to combine shelling and cleaning into one process.
[0005] The technical solution of this utility model is as follows: a chestnut shelling and cleaning integrated machine, comprising a processing box, a motor installed on the outside of the processing box, an active rotating shaft welded to the drive shaft of the motor, a squeezing roller fixedly connected to the outer wall of the active rotating shaft, multiple sets of fixing rods installed on the outside of the squeezing rollers, the multiple sets of fixing rods welded to the inside of the processing box, the multiple sets of fixing rods being distributed in an arc shape at equal distances on the inside of the processing box, a first pulley group fixedly connected to the outer wall of the active rotating shaft, a first driven shaft fixedly connected inside the first pulley group, two sets of first cams fixedly connected to the outer wall of the first driven shaft, a chestnut screen plate installed above the two sets of first cams, a water leakage screen plate installed below the chestnut screen plate, a water storage frame installed on the top of the water leakage screen plate, the water storage frame being fixedly connected to the inside of the processing box, multiple sets of spray nozzles installed on the side of the water storage frame, a water inlet pipe fixedly connected to the side of the water storage frame away from the multiple sets of spray nozzles, a chestnut shell discharge outlet opened on the outside of the processing box, and a chestnut discharge outlet opened on the side of the processing box away from the chestnut shell discharge outlet.
[0006] Preferably, by operating the motor, the motor drives the active rotating shaft to rotate via the drive shaft. When the active rotating shaft rotates, it drives the squeezing roller to rotate. Multiple sets of fixed rods are set below the squeezing roller. When the chestnut enters the outside of the squeezing roller, the multiple sets of squeezing plates on the squeezing roller squeeze the chestnut, thus separating the chestnut from the shell. The chestnut then falls through the through grooves between the multiple sets of fixed rods onto the chestnut screen plate for screening. At this time, the chestnut passes through the chestnut screen plate and enters the cleaning device, while the shell is discharged through the chestnut shell discharge outlet by the inclined vibrating chestnut screen plate. After falling, the chestnut rolls forward on the water leakage screen plate. At the same time, the external water pump is started, so that the connected water inlet pipe injects cleaning water into the water storage frame. Then, the water in the water storage frame is sprayed out from multiple sets of spray nozzles through water pressure to rinse the chestnut rolling on the water leakage screen plate, thereby achieving the effect of automatically cleaning the chestnut. This device has the functions of shelling and cleaning at the same time, reducing the time required for material processing and transfer, and improving work efficiency.
[0007] Preferably, an L-shaped mounting plate is fixedly connected to the side of the processing box, and the motor is fixedly connected to the inside of the L-shaped mounting plate.
[0008] Preferably, a feed hood is fixedly connected to the top of the processing box, and the top of the feed hood has a funnel-shaped structure.
[0009] Preferably, the screen plate has four sets of first sliding rods internally slidably connected, and each set of first sliding rods is provided with a first spring on the outside. Two sets of first springs are welded to the opening of the processing box, and the other two sets of first springs are welded to the top of the fixed plate.
[0010] Preferably, a second pulley set is fixedly connected to the outer wall of the first driven shaft, a second driven shaft is welded inside the second pulley set, and two sets of second cams are welded to the outer wall of the second driven shaft.
[0011] Preferably, the internal sliding connection of the drainage mesh plate has four sets of second sliding rods, and each set of second sliding rods is provided with a second spring on its outer wall. The second spring is welded to the inside of the processing box.
[0012] Preferably, a drain pipe is fixedly connected to the side of the processing box away from the water inlet pipe.
[0013] The beneficial effects of this utility model are:
[0014] This integrated machine for shelling and cleaning chestnuts utilizes a motor that drives a drive shaft to rotate. The rotating shaft in turn rotates a squeezing roller. Multiple sets of fixed rods are positioned below the squeezing roller. When a chestnut enters the squeezing roller, the squeezing plates on the roller press the chestnut, separating it from its shell. The chestnut then falls through a groove between the fixed rods onto a sieve plate for screening. The chestnuts pass through the sieve plate and enter the cleaning device, while the shells are discharged through the inclined, vibrating sieve plate to the shell outlet. After falling, the chestnuts roll onto a water-permeable screen. Simultaneously, an external water pump is activated, injecting cleaning water into a storage frame via a connected inlet pipe. The water pressure then sprays the water from the storage frame through multiple spray nozzles, rinsing the rolling chestnuts on the water-permeable screen, thus achieving automatic chestnut cleaning. This device simultaneously performs shelling and cleaning functions, reducing material processing and transfer time and improving work efficiency. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0023] Please see Figures 1-6This utility model provides an embodiment: a chestnut shelling and cleaning integrated machine, including a processing box 1, a motor 3 is arranged on the outside of the processing box 1, a drive shaft 4 is welded to the drive shaft of the motor 3, a squeezing roller 5 is fixedly connected to the outer wall of the drive shaft 4, multiple sets of fixing rods 7 are arranged on the outside of the squeezing roller 5, the multiple sets of fixing rods 7 are welded to the inner side of the processing box 1, and the multiple sets of fixing rods 7 are distributed in an arc shape at equal distances on the inner side of the processing box 1, a first pulley group 8 is fixedly connected to the outer wall of the drive shaft 4, and a first driven shaft 9 is fixedly connected inside the first pulley group 8. Two sets of first cams 10 are fixedly connected to the outer wall of the first driven shaft 9. A sieve screen plate 11 is arranged above the two sets of first cams 10, and a water leakage screen plate 18 is arranged below the sieve screen plate 11. A water storage frame 21 is arranged on the top of the water leakage screen plate 18. The water storage frame 21 is fixedly connected to the inside of the processing box 1. Multiple sets of spray nozzles 22 are installed on the side of the water storage frame 21. A water inlet pipe 23 is fixedly connected to the side of the water storage frame 21 away from the multiple sets of spray nozzles 22. A chestnut shell discharge outlet 25 is opened on the outer side of the processing box 1. A water inlet pipe 23 is opened on the side of the processing box 1 away from the chestnut shell discharge outlet 25. The chestnut outlet 26 is connected to a motor 3 that drives the drive shaft 4 to rotate. The rotation of the drive shaft 4 drives the compression roller 5 to rotate, thus squeezing the chestnut and separating the chestnut shell from the chestnut. Multiple sets of fixing rods 7 act as abutments against the chestnut, facilitating the squeezing action of the compression roller 5. The rotation of the drive shaft 4 drives the first pulley group 8 to rotate, which in turn drives the first driven shaft 9 to rotate. The rotation of the first driven shaft 9 then drives two sets of first cams 10 and the second pulley group 15 to rotate. The rotation of the two sets of first cams 10 can drive the sieve screen plate 11 to vibrate up and down. The sieve screen plate 11 is used to sieve chestnuts and chestnut shells. The water leakage screen plate 18 is used to filter the rinsing water. The water storage frame 21 is used to store and supply water to the multiple sets of spray nozzles 22. The multiple sets of spray nozzles 22 play the role of spraying chestnuts, thereby cleaning the surface of the chestnuts. The water inlet pipe 23 is used to connect to the water pump used to draw the rinsing water, thereby continuously supplying water to the water storage frame 21. The chestnut shell outlet 25 plays the role of discharging chestnut shells. The chestnut discharge port 26 plays the role of discharging the cleaned chestnuts.
[0024] Please see Figure 1 , Figure 2 In this embodiment, an L-shaped mounting plate 2 is fixedly connected to the side of the processing box 1, and the motor 3 is fixedly connected to the inner side of the L-shaped mounting plate 2; a feed cover 6 is fixedly connected to the top of the processing box 1; a drain pipe 24 is fixedly connected to the side of the processing box 1 away from the water inlet pipe 23; the L-shaped mounting plate 2 is used to fix the bearings used by the motor 3, the first driven shaft 9 and the second driven shaft 16; the feed cover 6 is used to put in the chestnut and at the same time plays a role in protecting the extrusion assembly; the drain pipe 24 plays a role in draining the wastewater generated after cleaning.
[0025] Please see Figure 4In this embodiment, four sets of first sliding rods 12 are slidably connected inside the screen plate 11. Each set of first sliding rods 12 is provided with a first spring 13 on its outside. Two sets of first springs 13 are welded to the opening of the processing box 1, and the other two sets of first springs 13 are welded to the top of the fixed plate 14. The four sets of first sliding rods 12 make the screen plate 11 slide up and down on its outer wall. The four sets of first springs 13 have deformation characteristics, so that the screen plate 11 can fall back after being pushed up by the two sets of first cams 10, thereby making the screen plate 11 vibrate up and down.
[0026] Please see Figure 5 In this embodiment, a second pulley group 15 is fixedly connected to the outer wall of the first driven shaft 9. A second driven shaft 16 is welded inside the second pulley group 15. Two sets of second cams 17 are welded to the outer wall of the second driven shaft 16. Four sets of second sliding rods 19 are slidably connected inside the drain mesh plate 18. A second spring 20 is provided on the outer wall of each set of second sliding rods 19. The second springs 20 are welded to the inner side of the processing box 1. The second pulley group 15 is used to drive the second driven shaft 16 to rotate. When the second driven shaft 16 rotates, it drives the two sets of second cams 17 to rotate. The two sets of second cams 17 can lift the drain mesh plate 18, so that the drain mesh plate 18 can vibrate up and down, thereby improving the water leakage effect. The four sets of second sliding rods 19 make the drain mesh plate 18 slide up and down on its outer wall. The four sets of second springs 20 have deformation characteristics, so that the drain mesh plate 18 can fall back after being lifted up by the two sets of second cams 17.
[0027] During operation, motor 3 drives drive shaft 4 to rotate via drive shaft. The rotation of drive shaft 4 drives squeeze roller 5 to rotate. Multiple sets of fixing rods 7 are located below squeeze roller 5. When the chestnut enters the squeeze roller 5, the multiple sets of squeezing plates on squeeze roller 5 squeeze the chestnut, separating it from the shell. The chestnut then falls through the grooves between the fixing rods 7 onto the sieve screen 11 for screening. After passing through the sieve screen 11, the chestnut enters the washing device, while the shell is subjected to tilting vibration. The chestnut screen plate 11 is guided to the chestnut shell discharge outlet 25 for discharge. After falling, the chestnuts roll forward on the water leakage screen plate 18. At the same time, the external water pump is started, so that the connected water inlet pipe 23 injects cleaning water into the water storage frame 21. Then, the water in the water storage frame 21 is sprayed out from multiple spray nozzles 22 through the water pressure to wash the chestnuts rolling on the water leakage screen plate 18, thereby achieving the effect of automatically cleaning the chestnuts. This makes the device have both shelling and cleaning functions, reducing the time required for material processing and transfer, and improving work efficiency.
[0028] Through the above steps, by setting up a shelling component to separate the chestnut shell from the chestnut, and by setting up a cleaning component to automatically clean the shelled chestnut, the time required for material processing and transfer is reduced, and work efficiency is improved, thus solving the existing problem of not being able to combine shelling and cleaning into one process.
