[0026] Specifically, in order to realize effective separation of walnut kernels and walnut shells, the separation assembly comprises a separation drum 7, the separation drum 7 is rotatably connected with the frame 1, a fan 8 is arranged between the separation drum 7 and the walnut kernel collection frame 5, and the fan 8 is fixedly connected with the frame 1; the separation drum 7 is a spiral drum, and the pitch of the spiral drum increases from left to right, so that the material can be naturally classified during rotation.

[0027] Further, in order to avoid that the mixed material which is not timely screened out during the separation process slides away from the end of the separation drum 7 away from the guide hopper 4, a baffle 9 is fixedly connected to the end of the separation drum 7 away from the guide hopper 4.

[0028] Specifically, a rotating shaft 10 is fixedly connected to the center position of the separation drum 7, a driving wheel I 11 is fixedly connected to the end of the rotating shaft 10 away from the guide hopper 4, a rotary motor 12 is fixedly arranged at one end of the frame 1 located at the driving wheel I 11, the fan 8 is located below the rotary motor 12, a driving wheel II 13 is fixedly connected to the output end of the rotary motor 12, and the driving wheel I 11 and the driving wheel II 13 are connected through a belt 14.

[0029] Furthermore, in order to achieve better separation effect and avoid material splashing during the separation process, the blower 8 is equipped with an air collection pipe 15, and the frame 1 is symmetrically fixed with two air guide plates 16 along the air outlet direction of the air collection pipe 15, and the air guide plates 16 are located below the separation drum 7.

[0030] Furthermore, in order to allow the walnut kernels to fall into different collection chambers for easier subsequent processing and management, the walnut kernel collection frame 5 is evenly distributed with several partitions 17, which divide the walnut kernel collection frame 5 into several collection chambers.

[0031] Working principle

[0032] As attached Figures 1-4 As shown, firstly, the mixture of walnut kernels and walnut shells is conveyed forward to the guide hopper 4 by the conveyor belt 2. After passing through the guide hopper 4, the mixture enters the separating drum 7, which is a solenoid drum with a gradually increasing pitch. The rotating motor 12 drives the separating drum 7 to rotate via the belt 14. As the separating drum 7 rotates, the mixture falls along with the walnut kernels and walnut shells with the corresponding pitch. During the falling process, a fan 8 is installed between the walnut kernel collection frame 5 and the separating drum 7. The fan 8 blows air out through the air collection pipe 15. For walnut kernels and walnut shells of the same size, the mass of the walnut kernel is greater than that of the walnut shell. Therefore, when subjected to the wind force, the walnut shell... The walnut kernels and shells are blown out and separated. As the pitch of the separating drum 7 gradually increases, the size of the falling walnut kernels and shells also gradually increases. The closer they are to the fan, the larger their size and the greater the wind force they receive. This prevents smaller walnut kernels from being blown into the collection frame along with larger walnut shells during separation, thus achieving efficient separation of walnut kernels and shells. Two air guide plates 16 are symmetrically fixed to the air outlet direction of the air collection pipe 15, which can concentrate the airflow, making the wind force stronger and more concentrated. This device achieves rapid and accurate separation of walnut kernels and shells. Moreover, this device has the advantages of simple structure, convenient operation, high separation efficiency, and significant separation effect, which can reduce labor intensity and improve production efficiency.
