[0029] See also Figure 1 , which is a walnut primary screening device 100 according to an embodiment of the utility model, includes a frame 10, a vibration screening mechanism 20 and a wind screening mechanism 30, wherein the vibration screening mechanism 20 and the wind screening mechanism 30 are both arranged on the frame 10.
[0030] See also Figure 1 The vibration screening mechanism 20 includes a feeding channel 21, a screening plate 22 and a vibrator 23. The feeding channel 21 is tilted on the frame 10, and the height of the feeding part of the feeding channel 21 is greater than the height of the discharging part of the feeding channel 21. The angle between the feeding channel 21 and the horizontal plane is 15°-30°, so that the walnuts after shelling can be prevented from piling up at the feeding port. The screening plate 22 is arranged above the feeding channel 21, and the screening plate 22 is provided with screening holes. The vibrator 23 is fixedly connected to the feeding channel 21. The vibrator 23 vibrates the feeding channel 21, so that the walnuts with completely shelled can fall into the feeding channel 21 through the screening holes for feeding, while the walnuts with incomplete shelling are left on the screening plate 22.
[0031] See also Figure 1 The vibration screening mechanism 20 also includes a sealing plate 24. The inner side wall of the discharge channel 21 is provided with a snap-in groove, and the sealing plate 24 is snapped into the snap-in groove. The sealing plate 24 is detachably connected to the discharge channel 21, and the sealing plate 24 seals the discharge position of the screening plate 22.
[0032] See also Figure 1 and Figure 2 The wind screening mechanism 30 includes a shell 31, a wind control component 32 and a wind screening driver 33. The shell 31 is fixedly connected to the frame 10. The shell 31 is provided with an air outlet 311. The end surface of the shell 31 away from the air outlet 311 is provided with an air inlet 312.
[0033] The air outlet 311 faces the feeding channel 21, the wind control component 32 is arranged in the housing 31, and the wind control component 32 includes a rotating roller 321 and a fan blade 322, the rotating roller 321 is rotatably connected to the housing 31, and the fan blade 322 is arranged at intervals along the circumference of the rotating roller 321, and the wind screen driver 33 is fixedly connected to the frame 10, and the rotating roller 321 is transmission-connected to the wind screen driver 33. The wind screen mechanism 30 can blow away impurities such as the wooden diaphragm, the outer membrane of the walnut kernel, and the broken walnut shell, which is more convenient for subsequent processing.
[0034] See also Figure 1 The wind screen mechanism 30 also includes a driving disk 34, a transmission disk 35 and a transmission belt 36. The driving disk 34 is connected to the wind screen driver 33 in a transmission manner. The transmission disk 35 is fixedly connected to the rotating roller 321. The transmission disk 35 is connected to the driving disk 34 in a transmission manner through the transmission belt 36.
[0035] The working principle of the walnut shelling device in this embodiment is as follows: when working, the sealing plate 24 is first inserted into the snap-in groove so that the sealing plate 24 is blocked at the unloading position of the screening plate 22, and the shelled walnuts are poured into the vibrating screening mechanism 20. During the falling process, the wind screening mechanism 30 blows away impurities such as the wooden diaphragm, the outer membrane of the walnut kernel and the broken walnut shells in the walnuts, and the remaining walnut kernels and walnut shells fall onto the screening plate 22. The vibrator 23 drives the unloading channel 21 and the screening plate 22 to vibrate at the same time, so that the walnuts with completely broken shells can fall into the unloading channel 21 through the screening holes for unloading, while the walnuts with incomplete shells remain on the screening plate 22.
[0036] The beneficial effects of the utility model are as follows: through the cooperation of the frame 10, the vibrating screening mechanism 20 and the wind screening mechanism 30, the walnuts with completely cracked shells and the walnuts with incomplete cracked shells can be automatically separated, thereby reducing the intensity of manual labor, improving production efficiency and reducing labor costs; the walnut primary screening device 100 can also remove impurities such as the wooden diaphragm, the outer membrane of the walnut kernel and the broken walnut shells in the walnut, making it more convenient for the subsequent processing of the walnuts with completely cracked shells.
[0037] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0038] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
