[0037] In this embodiment, in order to achieve the effect of uniform heating of partitioned material discharge, a feed processing assembly 5 is designed. Two side frames 5-1 are arranged at the bottom of the top cover 4, and a telescopic cylinder 5-2 is arranged at the top. The output end of the telescopic cylinder 5-2 is connected to a connecting rod 5-3. A plurality of evenly spaced intermediate frames 5-4 are arranged on the surface of the connecting rod 5-3. Both sides of the intermediate frame 5-4 are rotatably connected to a placement frame 5-5 through a pin shaft. The width of the placement frame 5-5 is less than the spacing between the two side frames 5-1. Round rods 5-6 are arranged on both sides of the placement frame 5-5. The round rods 5-6 can be used to place the placement frame 5-5. 5 is supported on the side frame 5-1. When the output end of the telescopic cylinder 5-2 is contracted, the placement frame 5-5 can be lifted upward through the middle frame 5-4. After being lifted, the angle will change. The round rod 5-6 slides on the surface of the side frame 5-1 to assist the support movement, so that the placement frame 5-5 can have an inclined angle. A discharge port 5-7 is opened on the outer surface of the placement frame 5-5. A second cylinder 5-8 is arranged at the bottom of the placement frame 5-5. The output end of the second cylinder 5-8 is connected to a connecting frame 5-9 and a side cover 5-10. The side cover 5-10 is located in the discharge port 5-7 and is used to open and close the discharge port 5-7 to control the discharge.

[0038] Furthermore, the discharging assembly 6 includes a pair of base frames 6-1, the base frames 6-1 are fixed on the two side surfaces of the lifter 3, and the third cylinder 6-2 is arranged on both sides of the outer surface of the lifter 3, and the output end of the third cylinder 6-2 is connected with a rack 6-3, and the lower end of the rack 6-3 is slidingly fitted with the surface of the base frame 6-1, and the outer surface of the processing shell 1 is rotatably connected with a pair of rotating seats 6-4, and a transmission gear 6-5 is arranged on the outside of the rotating seat 6-4, and the transmission gear 6-5 is meshed with the rack 6-3, and an extension frame 6-6 is arranged on the upper end surface of the rotating seat 6-4, and one end of the extension frame 6-6 is fixedly connected to a receiving hopper 6-7.

[0039] In this embodiment, in order to achieve the effect of receiving the nuts after heat treatment and discharging them, a discharging component 6 is designed. A base frame 6-1 and a third cylinder 6-2 are arranged on the back of the processing shell 1. The output end of the third cylinder 6-2 is connected to a rack 6-3. The back of the processing shell 1 is located above the rack 6-3 and is also rotatably connected to two rotating seats 6-4. The outer surface of the rotating seat 6-4 is provided with a transmission gear 6-5, which is meshed with the rack 6-3. The rotation of the rotating seat 6-4 can be controlled by the rack 6-3 and the transmission gear 6-5. An extension frame 6-6 and a receiving hopper 6-7 are arranged on the top of the rotating seat 6-4. When discharging, the discharging hopper can be located at the top to receive the fallen nuts, and then it can be rotated outward to discharge them outward in a concentrated manner.

[0040] Furthermore, the upper end of the side surface of the placement rack 5-5 extends outward to form an inclined structure.

[0041] In this embodiment, the outwardly extending inclined structure facilitates the insertion of the nut into the placement rack 5 - 5 .

[0042] Furthermore, the rotating seat 6-4 can be rotated 90° through the cooperation between the rack 6-3 and the transmission gear 6-5.

[0043] In this embodiment, the rotating seat 6-4 can be rotated outward through a rotation angle of 90° so that the opening faces the side, and the nut can slide outward.

[0044] Furthermore, the bottom of the placement rack 5-5 is a mesh-like, breathable hollow structure.

[0045] In this embodiment, the mesh-like hollow structure allows hot air to flow in the placement rack 5 - 5, thereby improving the heating effect.

[0046] Furthermore, the cross section of the receiving hopper 6-7 is a U-shaped structure, and both sides of the upper end of the receiving hopper 6-7 are tilted excessively outwards.

[0047] In this embodiment, the U-shaped structure, in combination with the outward tilt angle, can increase the material receiving range, ensuring that all nuts dropped from the discharge port 5-7 can fall into the receiving hopper 6-7.

[0048] When heat treatment is required, start the lifter 3, lift the top cover 4 upward so that the whole structure is located outside, then put the nut into the placement rack 5-5, and after entering, start the heating base 2 to start heat treatment. After the treatment is completed, it is raised to the outside again, and then start the third cylinder 6-2 to push the rack 6-3 outward, drive the transmission gear 6-5 to make the rotating seat 6-4 rotate upward 90°, so that the receiving hopper 6-7 is located at the bottom of the placement rack 5-5, and then start the telescopic cylinder 5-2 to retract and pull the connecting rod 5-3, so that the middle frame 5-4 rises upward, so that the placement rack 5-5 has an inclined angle, and then start the second cylinder 5-8 to push the side cover 5-10 outward, open the discharge port 5-7 to make the nut slide into the receiving hopper 6-7, and then place the received containers on both sides of the processing shell 1, and then start the third cylinder 6-2 to control the receiving hopper 6-7 to rotate outward to discharge the material.

[0049] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
