[0004] During the processing of almonds, the almond shells and cores need to be separated. The current processing method is to separate the almond shells and cores, and then crush the shells by rubber rollers. However, due to the different sizes of the processed almonds, the relative degree of rolling of the rubber rollers on different almonds is different, which results in incomplete crushing of some almond shells and excessive pressure on some almonds, resulting in broken and damaged cores, which reduces the quality of almonds.

[0033] The following will be combined with the accompanying drawings in the present invention Figure 1-Figure 7 , clearly and completely describe the specific technical solutions of the present invention;

[0035] The present embodiment provides an almond rolling, shelling and screening device, which includes an outer shell 1. A feed hopper 2 is provided at the top of one end of the outer shell 1. The bottom of the feed hopper 2 extends to a screening mechanism 3 movably connected to the outer shell 1. A screening hopper driven by a vibration motor 5 is provided in the screening mechanism 3 to perform gravity screening of almonds. The rear end of the screening mechanism 3 is connected to a rolling mechanism 4. The rolling mechanism 4 includes a supporting conveyor belt 41 and a rolling roller 42 with a variable diameter to roll the almonds in different areas. A screen plate 43 with a vibration motor 5 is provided on the lower side of the supporting conveyor belt 41. The tail end of the screen plate 43 extends to the discharge port 7 at the tail end of the outer shell 1, and a waste port 8 is provided on the lower side.

[0036] Among them, the screening mechanism 3 includes a supporting airbag 31, a screening bucket 32 ​​and a diverter nozzle 34. The screening bucket 32 ​​is movably connected to the outer shell 1 through the supporting airbag 31. The screening bucket 32 ​​has a variable diameter structure with a large horizontal diameter at the front end and a large vertical diameter at the rear end. A vibration motor 5 is fixed to the outer wall, and a diverter nozzle 34 for vertical diversion is movably connected to the rear end. The other end of the diverter nozzle 34 is connected to the rolling mechanism 4 through a connecting hose 35.

[0037] Specifically, the supporting airbag 31 includes a connecting frame 311 and an L-shaped airbag 312. The connecting frame 311 is fixed inside the housing 1. The L-shaped airbag 312 is adhered to the inner side of the connecting frame 311, and the screening bucket 32 ​​is supported and fixed by the L-shaped airbag 312.

[0038] The elastic support of the screening bucket 32 ​​by the L-shaped airbag 312 can effectively reduce the transmission of vibration of the screening bucket 32 ​​and the resonance of the housing 1, thereby achieving the effect of reducing noise.

[0039] Specifically, the screening bucket 32 ​​includes a bucket body 321 and a filter screen 322. The bucket body 321 is a U-shaped structure with an open top surface, a bottom surface, and a tail end surface. The bottom surface is closed by the filter screen 322, and the tail end surface is connected to the diversion nozzle 34 through a mesh connection pocket piece 33.

[0040] Through the variant structure of the screening bucket 32, during the vibration process, the almonds will move toward the tail end along the slope of the bottom filter 322, and under the mutual action of the almonds, they will be vertically stratified according to size, so as to achieve the differentiation and screening of almonds of different sizes. At the same time, the filter 322 at the bottom can also screen out impurities and dust on the surface of the almonds during the vibration process, playing multiple roles. The diverter nozzle 34 is connected to the screening bucket 32 ​​through the mesh, which can also reduce the transmission of vibration of the screening bucket 32, extend the life of other components and reduce resonance noise.

[0041] Specifically, the flow dividing nozzle 34 includes a flow dividing plate 341 and a guide nozzle 342. The flow dividing plate 41 is provided with openings in an array along the vertical direction. The back side of the opening is connected to the connecting hose 35. The side of the opening facing the screening bucket 32 ​​is provided with a laterally protruding guide nozzle 342.

[0042] By setting the diverter plate 341 and the connecting hose 35, the vertically layered almonds are diverted and changed into horizontal parallel partitions for easy crushing. The setting of the guide nozzle 342 reduces the free flow of almonds at the opening position of the diverter plate 341, plays a guiding role, and improves the partitioning accuracy.

[0043] Among them, the rolling mechanism 4 includes a supporting conveyor belt 41, a rolling roller 42 and a screen plate 43. The end structure of the screening mechanism 3 is connected to the supporting conveyor belt 41 for partitioned discharging. A rolling roller 42 with a variable diameter is arranged across the upper side of the supporting conveyor belt 41. The rolling roller 42 is driven by a driving motor 6 arranged on the outside of the outer shell 1 to roll the almonds. There is an inclined screen plate 43 movably connected to the outer shell 1 on the lower side of the end of the supporting conveyor belt 41. A vibration motor 5 is fixed on the back of the screen plate 43, and a winnowing machine is installed on the corresponding lower side of the outer shell 1 structure.

[0044] Specifically, a plurality of rolling rollers 42 are arranged along the conveying direction of the supporting conveyor belt 41, and the installation height of the rolling rollers 42 closer to the end of the supporting conveyor belt 41 is lower;

[0045] By setting the heights of the multiple groups of rolling rollers 42, the crushing operation of the nut shell is carried out step by step, thereby avoiding the situation where the nut shell presses on the nut kernel and damages the nut kernel due to excessive pressure caused by a single high-intensity rolling.

[0046] Specifically, the supporting conveyor belt 41 includes a mounting frame 411, a conveyor belt 412 and a connecting nozzle 413. The mounting frame 411 is fixedly connected to the inner side of the outer shell 1, and the conveyor belt 412 is arranged on the mounting frame 411. The end of the mounting frame 411 close to the screening mechanism 3 is laterally arranged with a connecting nozzle 413 extending to the top of the conveyor belt 412. The connecting nozzle 413 is connected in turn to the connecting hose 35 vertically connected to the diverter nozzle 34.

[0047] Furthermore, a partition plate 414 is provided on the mounting frame 411 between adjacent connecting nozzles 413 along the conveying direction of the conveyor belt 412, and a corresponding groove is provided on the rolling roller 42 to separate different diameter sections of the rolling roller 42;

[0048] The partition 414 is used to separate the partitioned almonds to prevent the almonds from splashing to other partition positions due to possible force transfer between the almonds during the crushing process, thereby ensuring the partition accuracy.

[0049] A method for shelling almonds using the almond rolling shelling and screening device comprises the following steps:

[0050] Step 1: Select and dehumidify: Select fresh, plump almonds of similar size and shape, and bake them at 150° with low-temperature hot air to reduce the moisture content of the shell, increase the crispness of the shell, and facilitate the breaking of the shell;

[0051] Step 2: Feed screening: Add the dried almonds into the screening mechanism 3 from the device feed hopper 2, start the device, and the almonds in the screening bucket 32 ​​will be vertically stratified under the influence of vibration, with smaller ones falling to the bottom and larger ones floating on the top of the screening bucket 32.

[0052] Step 3: Zoned crushing: The sieved almonds are separated into different sizes under the action of the diversion nozzle 34, enter the supporting conveyor belt 41 of the crushing mechanism 4, and are crushed and shelled by the variable diameter crushing roller 42 above.

[0053] Step 4, shelling and discharging: the crushed shells and almond kernels fall onto the sieve plate 43 along the supporting conveyor belt, and the shell debris mixed in the kernels is removed through the vibration of the sieve plate 43 and the blowing of the bottom air separation mechanism. The kernels are discharged through the discharge port 7, and the shells and debris are discharged through the bottom waste port 8.
