[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0029] Example 1

[0030] See also Figure 1-7The present invention provides a walnut shelling device, comprising a mounting frame 1, a switching assembly 2 is arranged on one side of the mounting frame 1, and the switching assembly 2 comprises a rotating wheel 201, a connecting column 202, a first bevel gear 203, a mounting ring 204 and a walnut placing cavity 205, a rotating cavity for rotating the rotating wheel 201 is opened inside one side of the mounting frame 1, one end of the rotating wheel 201 is fixedly connected to one end of the connecting column 202, and the outer side wall of the connecting column 202 is fixedly connected with the first bevel gear 203, the top end of the first bevel gear 203 is meshed with the bottom end of the second bevel gear 3, and the top end of the second bevel gear 3 is fixedly connected to the output end of the first motor 4, the first motor 4 is a reduction motor structure, the outer wall of the connecting column 202 away from the rotating wheel 201 is fixedly connected to the inner side wall of the mounting ring 204, and the outer side wall of the mounting ring 204 is fixedly connected with four walnut placing cavities 205 for placing walnuts at equal intervals.

[0031] During the process of cracking the walnut shells, the first motor 4 is set to output the operation, and then the first motor 4 drives the second bevel gear 3 to rotate at a uniform speed, so that the second bevel gear 3 drives the meshing first bevel gear 203 to rotate. In this way, the rotation of the first bevel gear 203 drives the mounting ring 204 and the four walnut placing cavities 205 fixedly connected to the outer wall of the mounting ring 204 for placing walnuts to rotate, so that seamless material connection and unloading of the crushed walnuts can be achieved.

[0032] A first transmission pipe 5 is arranged above the switching component 2, and the first transmission pipe 5 passes through and is fixedly connected to the top of the mounting frame 1, a feed hopper 6 with a conical structure is fixedly connected to the top of the first transmission pipe 5, and a connecting cavity 7 is opened through one side of the lower side of the first transmission pipe 5, and a mounting shell 8 fixedly connected to the outer wall of the first transmission pipe 5 is arranged at one end of the connecting cavity 7, a first metal barrier net 9 and a first metal air inlet net 10 are fixedly connected to the two ends of the interior of the mounting shell 8 respectively, and a first centrifugal fan 11 is fixedly connected to the inner middle section of the mounting shell 8.

[0033] By setting up the first centrifugal fan 11, the centrifugal force generated by the output operation of the first centrifugal fan 11 during use, and the centrifugal force generated by the first centrifugal fan 11 adsorbs the walnuts horizontally located inside the first transmission tube 5 onto the surface of the first metal barrier net 9 through the first metal barrier net 9 and the connecting cavity 7. In this way, after the shelling operation of the walnut placement cavity 205 at the top of the switching component 2 is completed, the first centrifugal fan 11 stops operating after moving to the next walnut placement cavity 205, so that the walnut is fed into the walnut placement cavity 205 vertically below to continue the shelling operation. After the first centrifugal fan 11 stops the output operation, the output operation is immediately performed again, and then the next walnut is centrifugally adsorbed.

[0034] A transmission pump 13 is fixedly connected to the top of the mounting frame 1, and the output end of the transmission pump 13 is connected to the top of a discharge head through a first feed pipe 12.

The input end of the transmission pump 13 is connected to the top of a bellows 15 through a second feed pipe 14, and the bottom end of the bellows 15 is connected to the top of a suction head 16.

[0035] By setting up the transmission pump 13, before crushing the walnuts, the bellows 15 can be freely adjusted and the suction head 16 is placed in the walnut storage container that needs to be crushed. The transmission pump 13 outputs the operation to suck the walnuts one by one into the second feed pipe 14, and then transmits them to the inside of the feed hopper 6 through the first feed pipe 12 in cooperation with the discharge head. In this way, automatic loading can be achieved while avoiding the problems of poor efficiency and poor shelling effect caused by processing a large number of walnuts at the same time.

[0036] A storage chamber 20 is fixedly connected to one side of the mounting frame 1 close to the switching assembly 2, and the top of the storage chamber 20 is communicated with the bottom end of the second transmission tube 19, the top of the second transmission tube 19 is fixedly connected with a receiving hopper 17 with a conical structure, and the inner side wall of the receiving hopper 17 is symmetrically fixedly connected with a silicone baffle 18, the inner walls on both sides of the storage chamber 20 are provided with guide grooves 21 with a "convex" structure, and the interior of the guide grooves 21 is horizontally movably connected with guide sliders 22 with a "convex" structure, the guide sliders 22 are fixedly connected to both sides of the storage box 23, and the storage box 23 forms a sliding structure with the storage chamber 20 through the guide sliders 22, the interior of the storage box 23 is provided with a metal screen 25, and the outer side wall of the metal screen 25 is fixedly connected with a silicone resistance block 24, and the outer side wall of the silicone resistance block 24 is in resistance with the inner side wall of the storage box 23.

[0037] By setting up the receiving hopper 17, when the walnut placing chamber 205 circulates and rotates, the walnuts with broken shells in the walnut placing chamber 205 below will fall into the receiving hopper 17 and be effectively buffered by the silicone baffle 18. At the same time, when the broken walnuts enter the storage chamber 20 through the second transmission tube 19 and are stored in the storage box 23, the metal screen 25 installed in the storage box 23 can screen the debris and residues generated by the crushing. The operator only needs to slide out the storage box 23 regularly to process the broken walnuts and the sun-screened debris and residues.

[0038] A connecting frame 26 is vertically fixedly connected to the top of the storage cavity 20, and an upper side of the connecting frame 26 is fixedly connected to one of the side walls of the mounting seat 27. The mounting seat 27 is movably connected with a connecting rod 28, and one end of the connecting rod 28 is fixedly connected to a shelling head 29 for walnut shelling, and the shelling head 29 is away from and one end of the connecting rod 28 is fixedly connected to a plurality of hemispherical structured protrusions 30, and the protrusions 30 are metal material structures. The other end of the connecting rod 28 is fixedly connected to a connecting frame 31 with a "concave" structure, and the interior of the connecting frame 31 is hinged to one end of a first connecting block 32, and the other end of the first connecting block 32 is fixedly connected to a second connecting block 33, and the end of the second connecting block 33 away from the first connecting block 32 is hinged to the front end of a turntable 34 through a bearing, and the rear end center point of the turntable 34 is fixedly connected to the output end of the second motor 35.

[0039] By setting up the second motor 35, during the walnut crushing operation, the turntable 34 is rotated by the output operation of the second motor 35, and the time for the turntable 34 to rotate one circle matches the switching time of the walnut placement chamber 205 and the time for the first transmission tube 5 to feed the walnuts into the walnut placement chamber 205, so as to realize the circulating operation. When the turntable 34 is rotating, one end of the first connecting block 32 is hinged to the connecting frame 31, so that the shell breaking head 29 is driven to circulate left and right through the connecting rod 28. When the shell breaking head 29 moves to the inside of the walnut placement chamber 205, the shell breaking operation is completed for the walnuts in the walnut placement chamber 205.

[0040] The interior of the mounting seat 27 is fixedly connected with a dust removal pipe 41 with an "L"-shaped structure, and one end of the dust removal pipe 41 extends to the outside of one side of the mounting seat 27 near the shell breaking head 29, and the end of the dust removal pipe 41 near the shell breaking head 29 is fixedly connected with a second metal barrier net 42, and the bottom end of the dust removal pipe 41 extends to the outside of the bottom end of the mounting seat 27, and is inserted into the top end of the connecting shell 36, the top of the connecting shell 36 is snap-connected with the bottom end of the mounting seat 27, the interior of the connecting shell 36 is fixedly connected with a connecting frame 37 with a hollow structure, and the interior of the connecting frame 37 is fixedly connected with a dust bag 38, a second centrifugal fan 39 fixedly connected to the inside of the connecting shell 36 is arranged below the dust bag 38, and a second metal air inlet net 40 is fixedly connected to the bottom end of the connecting shell 36.

[0041] By setting up the connecting shell 36, during use, when the walnut shelling operation is carried out, by starting the second centrifugal fan 39, the connected dust removal pipe 41 has centrifugal suction, so that the debris and dust generated by the walnuts after being crushed by the shelling head 29 can be sucked into the interior of the connecting shell 36 through the second centrifugal fan 39 and the dust removal pipe 41, and blocked by the dust bag 38, so that the sucked dust and debris are stored in the interior of the connecting frame 37. In this way, it is possible to effectively avoid a large amount of debris and dust generated by the walnut crushing operation, resulting in a poor working environment, and the debris falling into the storage chamber 20, which will also cause the crushed walnut kernels to be adhered to a large amount of debris and need to be processed.

[0042] The specific use process of this embodiment is as follows:

[0043] First, before crushing the walnuts, the bellows 15 is adjusted to move freely, and the suction head 16 is placed in the walnut storage container that needs to be crushed. The transmission pump 13 outputs the operation to suck the walnuts one by one into the second feed pipe 14, and then transmits them to the inside of the feed hopper 6 through the first feed pipe 12 and the discharge head, so that automatic feeding can be achieved;

[0044] Secondly, the centrifugal force generated by the output operation of the first centrifugal fan 11 is adsorbed on the surface of the first metal barrier net 9 through the first metal barrier net 9 and the connecting cavity 7 to the walnuts horizontally located inside the first transmission tube 5. In this way, after the shelling operation of the walnut placement cavity 205 at the top of the switching component 2 is completed, the first centrifugal fan 11 moves to the next walnut placement cavity 205 and stops operating. In this way, the walnut is fed into the walnut placement cavity 205 vertically below to continue the shelling operation. After the first centrifugal fan 11 stops the output operation, the output operation is immediately performed again, and then the next walnut is centrifugally adsorbed;

[0045] Afterwards, the second motor 35 performs output operation to rotate the turntable 34. When the turntable 34 rotates, one end of the first connecting block 32 is hinged to the connecting frame 31, so that the shell breaking head 29 is driven to circulate left and right through the connecting rod 28. When the shell breaking head 29 moves to the inside of the walnut placement cavity 205, the shell breaking operation is completed for the walnuts in the walnut placement cavity 205.

[0046] Then, the output operation is performed by the first motor 4, and the second bevel gear 3 is driven to rotate at a uniform speed by the first motor 4, so that the second bevel gear 3 drives the meshing first bevel gear 203 to rotate, and the rotation of the first bevel gear 203 drives the mounting ring 204 and the four walnut placing cavities 205 for placing walnuts fixedly connected to the outer wall of the mounting ring 204 to rotate, so that seamless material connection and crushed walnut unloading can be achieved;

[0047] Finally, when the walnut placement chamber 205 circulates and rotates, the walnuts in the lower walnut placement chamber 205 after the shells are broken will fall into the receiving hopper 17 and be effectively buffered by the silicone baffle 18. At the same time, when the broken walnuts enter the storage chamber 20 through the second transmission tube 19 and are stored in the storage box 23, the metal screen 25 installed in the storage box 23 can screen the debris and residues generated by the crushing. The operator only needs to slide the storage box 23 out regularly to process the broken walnuts and the screened debris and residues. In this way, the walnut shelling device is used.
