Detailed Description
The technical solutions of the present invention are further described in detail below with reference to the accompanying drawings, but the scope of the present invention is not limited to the following.
As shown in fig. 1 to 5, the shell breaking machine based on the pretreated walnuts comprises a frame 100, an impeller feeding device 200 and a double-roller extruding device 300, wherein the impeller feeding device 200 and the double-roller extruding device 300 are both arranged on the frame 100, and the walnuts subjected to pretreatment such as cutting, size classification and the like are put into the impeller feeding device 200 and then fed to the double-roller extruding device 300 for extruding and shell breaking.
The impeller feeding device 200 comprises a feeding hopper 210, a material distribution barrel 220 and a feeding plate 230, wherein the material distribution barrel 220 is cylindrical, the material distribution barrel 220 is horizontally arranged, a feeding hole and a discharging hole are formed in the cylindrical surface of the material distribution barrel 220, the feeding hopper 210 is arranged above the material distribution barrel 220, the feeding hopper 210 is fixedly connected with the material distribution barrel 220, the inner cavity of the feeding hopper 210 is communicated with the inner cavity of the material distribution barrel 220 through the feeding hole, the feeding plate 230 is obliquely arranged, the feeding plate 230 is arranged below the discharging hole, and one end of the feeding plate 230 is fixedly connected with the material distribution barrel 220; the rotating shaft 221 is rotatably arranged in the material separating barrel 220, a plurality of blades 222 are circumferentially and uniformly distributed on the cylindrical surface of the rotating shaft 221, and one end, far away from the rotating shaft 221, of each blade 222 is close to the inner wall of the material separating barrel 220. In practice, the distance between adjacent blades 222 is determined according to the size of the walnuts selected after the grading pretreatment, and the gap between adjacent blades can only contain the next row of walnuts. When the walnut sorting machine is used, the rotating shaft 221 is driven to rotate, the rotating shaft drives the blades 222 to rotate, walnuts are effectively sorted under the action of the blades 222, and then the walnuts are discharged from the feeding plate 230 of the discharge hole under the action of self weight. The double-roller extrusion device 300 is arranged below one end of the feeding plate 230 far away from the material separating cylinder 220, and walnuts discharged by the feeding plate 230 enter the double-roller extrusion device 300 to be extruded by the double-roller extrusion device 300, so that the shell breaking process is completed. In the implementation process, the feeding plate 230 is provided with a plurality of guide chutes 231, and walnuts can orderly enter the double-roller extrusion device 300 through the feeding plate 231 in the feeding process, so that the blockage in the feeding process is avoided, and the feeding efficiency is ensured. Preferably, an arc-shaped baffle plate 233 is arranged at one end of the feeding plate 230, which is far away from the material separating cylinder 220, and the baffle plate 233 is used for enabling walnuts falling from an outlet of the guide chute 231 to vertically fall, so that the walnuts can directly enter a squeezing area of the double-roller squeezing device 300, and cannot be obliquely thrown out under the guidance of the inclined guide chute 231, and thus the walnuts collide with rollers of the double-roller squeezing device 300 to generate unnecessary bounce, and therefore, the efficiency of the whole shell breaking machine can be ensured.
The pair-roller pressing device 300 includes two pressing rollers 320 which are arranged in parallel and symmetrically. The squeeze roller 320 is a split structure, and includes a roller 321, a central shaft 322 and two end plates 323, the roller 321 is a hollow cylinder structure, the central shaft 322 is fixed and concentrically disposed in the roller 321, the two end plates 323 are respectively fixedly connected to two ends of the roller 321, the two end plates 323 are both fixedly connected to the central shaft 322, and two ends of the central shaft 322 are rotatably connected to the frame 100.

A plurality of V-shaped ring grooves 3211 are processed on the outer surface of the roller 321, and a straight roller section 3212 is formed between two adjacent V-shaped ring grooves 3211. When the walnut shell breaking device is used, the V-shaped ring grooves 3211 of the two extrusion rollers 320 are oppositely arranged, the gap size of the radial shell breaking working area is slightly smaller than that of a walnut, and after the walnut falls into the two V-shaped ring grooves 3211, the walnut is extruded by four points under stress along with the rotation of the two extrusion rollers 320 until the shell breaking is completed. In practical application, if no axial distance is reserved among the V-shaped ring grooves 3211 on the squeezing roller 320, only small-sized walnuts can be cracked, and when the size of a walnut is larger than that of the V-shaped ring groove 3211, two adjacent walnuts interfere with each other and cannot enter the V-shaped ring groove 3211; if the depth of the V-shaped ring groove 3211 is deepened, the radial working interval of the two squeezing rollers 320 at the V-shaped ring groove 3211 is enlarged, and the shell breaking of the small-size walnuts cannot be effectively completed. Therefore, in the embodiment, a straight roller section 3212 is formed between two adjacent V-shaped annular grooves 3211, so that a large enough axial distance exists between the two adjacent V-shaped annular grooves 3211, and a blanking space is reserved, thereby meeting the requirements for breaking shells of small-size walnuts and large-size walnuts, and being more practical.
In implementation, the pair of roller pressing devices 300 further includes two driving devices, the two driving devices are respectively used for driving the two central shafts 322 to rotate, the rotation directions of the two central shafts 322 are opposite, and the two pressing rollers 320 are driven to rotate inward, so as to complete the pressing process.
The drive device can be driven in various forms such as direct drive by a motor and belt drive, and comprises a motor 351, a driving chain wheel 352, a driven chain wheel 353 and a chain 354, wherein the motor 351 is fixedly arranged on the rack 100, the driving chain wheel 352 is fixedly sleeved on an output shaft of the motor 351, the driven chain wheel 353 is fixedly sleeved at one end of the central shaft 322, and the driving chain wheel 352 and the driven chain wheel 353 are in transmission connection through the chain 354. Through the transmission form of the chain transmission, high-power transmission can be realized, the phenomenon of material blockage in the walnut crushing process is avoided, the accurate transmission ratio can be ensured, the rotating speeds of the two extrusion rollers 320 are the same, and the extrusion force of the walnut is smooth and stable when the walnut is extruded.
Further, when the rotating shaft 221 for feeding is driven, a motor a241, a driving sprocket a242, a driven sprocket a243 and a chain a244 are provided, the motor a241 is fixedly provided on the frame 100, the driving sprocket a242 is fixedly sleeved on the output shaft of the motor a241, the driven sprocket 243 is fixedly sleeved on one end of the rotating shaft 221, and the driving sprocket 242 and the driven sprocket 243 are in transmission connection through the chain 244.

when the two squeezing rollers 320 are used for cracking the walnut, the walnut is squeezed and cracked by the opposite V-shaped ring grooves 3211 on the two squeezing rollers 320. The distance between the two opposite V-shaped ring grooves 3211 is set as a cracking working gap, in order to ensure that the walnut is cracked, the difference between the size of the extruding cracking gap and the transverse diameter of the walnut is necessarily smaller than the cracked compression deformation amount of the walnut, the larger the difference is, the higher the cracking rate is, but if the difference is too large, the walnut is continuously extruded after being cracked, and the higher kernel loss rate is caused. Therefore, the gap between the two squeeze rollers 320 needs to match the size of the walnuts to improve the kernel exposure rate. The sizes of the walnuts cannot be completely uniform, and the squeezing rollers 320 arranged at fixed positions can only effectively break the shells of the walnuts under certain grading sizes.
for the above reasons, the pair of roller pressing devices 300 further includes two fixed bearing seats 330 and two adjustable bearing seats 340, the fixed bearing seats 330 are fixedly disposed on the frame 310, two ends of one central shaft 322 are respectively connected with the two fixed bearing seats 330 through bearings, the adjustable bearing seats 340 are slidably disposed on the frame 310, and two ends of the other central shaft 322 are respectively connected with the two adjustable bearing seats 340 through bearings. One extrusion roller 320 is relatively fixedly arranged, the guide groove 231 on the feeding plate 230 is matched with the V-shaped ring groove 3211 of the extrusion roller 320, so that the walnut can be conveniently taken by the extrusion roller, and the other extrusion roller 320 can slide under the action of the adjustable bearing seat 330, so that the distance between the two extrusion rollers 320 can be adjusted, and the walnut shell breaking device can adapt to effective shell breaking of walnuts with different sizes.
During specific implementation, vertical plates 341 are disposed on two sides of the adjustable bearing seat 340, the vertical plates 341 are fixedly disposed on the rack 310, an adjusting screw 342 is connected to the vertical plates 341 through threads, and by rotating the adjusting screw 342, an end of the adjusting screw abuts against the adjustable bearing seat 340 to enable the adjustable bearing seat to slide on the rack 100. Since the distance adjusting devices are installed at both ends of the squeeze roller 320 to simultaneously adjust the distance between the rollers, if the distance adjusting devices are not uniform at both ends, the rollers may be horizontally inclined, and breakage and damage may occur. Therefore, a graduation mark 343 is further provided on the frame 100, and the graduation mark 343 is used for indicating the position of the adjustable bearing seat 340. The inner side of the adjustable bearing seat 340 is used as a standard, and the two sides of the roller can be adjusted at the same distance to ensure the same distance adjustment at the two sides of the roller during each distance adjustment, so that the shell breaking efficiency is further ensured.
Further, the motor 351 for driving the central shaft 322 connected with the adjustable bearing seat 340 to rotate is also provided with an adjusting device with the same structure, and the adjusting device is used for adjusting the position of the motor 351 synchronously after adjusting the position of the adjustable bearing seat 340, so that the reliability of chain transmission is ensured.
furthermore, the roller 321 is made of 304 stainless steel, which can be used as food-grade stainless steel to ensure the food safety of walnut kernel, and the hardness of the material also meets the requirement of walnut kernel shell breaking.
Furthermore, the outer surface of the V-shaped ring groove 3211 is processed with net-shaped lines to increase the friction force of the walnut during extrusion, avoid the rotation of the walnut, enable the walnut to bear the extrusion completely, and improve the extrusion efficiency.
Furthermore, the outer surface of the roller section 3212 is wrapped by a PVC belt, so that the jumping of walnuts on the surface of the roller 21 during discharging is reduced, the walnuts enter an extrusion state as soon as possible, and the extrusion efficiency is improved. Set up the PVC area simultaneously and can also play the effect of rightting to the extruded walnut, increase the adaptability of walnut at the extrusion workspace, and then increase the surperficial broken area of walnut, improve high dew benevolence rate.
