[0023] The following is in conjunction with the appendix Figures 1-3 The present invention will be described in further detail below.

[0024] Please refer to the attached diagram in the instruction manual. Figure 1 , Figure 2 and Figure 3 One embodiment of this utility model is a heat treatment device for agricultural machinery castings, including a heating box 1. Several electric heating plates 11 are fixedly arranged on the inner side wall of the heating box 1. The several electric heating plates 11 work together to facilitate heating of the castings inserted into the heating box 1, so as to realize heat treatment of the castings.

[0025] It should be noted that the electric heating plate 11 is controlled by existing control equipment, and electric heating for heat treatment of castings is also an existing technology.

[0026] A placement rack 2 is movably inserted into the heating box 1. The placement rack 2 includes two fixed plates 21. A turntable 22 is rotatably inserted into each of the opposite sides of the two fixed plates 21. Each of the two turntables 22 has a limit groove 23 on the side facing the inner wall of the fixed plate 21. The opposite sides of the two turntables 22 are fixedly connected by two connecting plates 24. Fastening bolts 25 are threaded into the side walls of the two connecting plates 24. The two connecting plates 24 facilitate the fixing of the two turntables 22 to the two fixed plates 21 together. The fastening bolts 25 facilitate the fixing of the casting between the two connecting plates 24. The turntables 22 enable the connecting plates 24 to drive the casting to rotate, so as to heat the casting from all directions.

[0027] A rotating mechanism 3 is rotatably installed inside the placement rack 2. The rotating mechanism 3 is used to control the rotation of the casting. The rotating mechanism 3 includes a control disk 31 and a control rod 32. One end of the control rod 32 is inserted into the fixed plate 21 and is movably connected to the inner wall of the limiting groove 23. Several limiting posts 33 are fixedly installed at the end of the control rod 32 inserted into the limiting groove 23. The several limiting posts 33 slide in cooperation with the inner wall of the limiting groove 23. The other end of the control rod 32 extends out of the fixed plate 21 and is fixedly connected to the inner wall of the control disk 31. A handle 34 is fixedly installed on the outer wall of the control disk 31. The handle 34 makes it easy for the operator to drive the control disk 31 and the control rod 32 to rotate. At this time, the limiting posts 33 cooperate with the limiting groove 23 to drive the turntable 22 to rotate synchronously. Thus, the turntable 22 drives the connecting plate 24 and the casting to rotate, so as to heat the casting from all directions.

[0028] A ring 26 is rotatably inserted into the side wall of the fixed plate 21. A first spring 27 is fixedly installed on the side wall of the ring 26. The end of the first spring 27 away from the ring 26 is fixedly connected to the inner wall of the control disk 31. The side wall of the fixed plate 21 has several positioning holes 28 in a ring shape. Several positioning rods 35 are fixedly installed on the side of the control disk 31 facing the fixed plate 21. The positioning rods 35 are movably inserted into the inner wall of the positioning holes 28. The first spring 27 facilitates pulling the control disk 31 towards the fixed plate 21, thereby causing the positioning rods 35 to be inserted into the positioning holes 28, so as to fix the position of the control disk 31, the control rods 32 and the turntable 22. When it is necessary to rotate the control disk 31, the operator pulls the control disk 31 to move it, causing the positioning rods 35 to separate from the positioning holes 28, so that the operator can drive the control disk 31 and the control rods 32 to rotate.

[0029] The placement rack 2 is equipped with several striking mechanisms 4, which are used to shake off the debris on the surface of the casting. The outer wall of the turntable 22 is provided with several grooves 29.

[0030] The inner wall of the fixing plate 21 has two symmetrical mounting slots 210. The number of striking mechanisms 4 corresponds to the number of mounting slots 210, and the striking mechanisms 4 are installed in the mounting slots 210. The mounting slots 210 facilitate the installation of the striking mechanisms 4.

[0031] The striking mechanism 4 includes a striking rod 41 and a second spring 42. The striking rod 41 is movably disposed in the mounting groove 210. The striking rod 41 is connected to the inner wall of the mounting groove 210 by the second spring 42. The end of the striking rod 41 extends out of the mounting groove 210 and slides in cooperation with the outer wall of the turntable 22 and the inner wall of the groove 29. The second spring 42 facilitates the pulling of the end of the striking rod 41 to always contact the outer wall of the turntable 22. When the turntable 22 rotates to the point where the groove 29 coincides with the striking rod 41, the second spring 42 pulls the striking rod 41 to insert it into the groove 29 and impacts the inner wall of the groove 29, causing the turntable 22 and the casting to vibrate, thereby facilitating the shaking off of debris from the surface of the casting.

[0032] A collection box 5 is movably inserted into the side wall of the heating box 1, which facilitates the collection of debris shaken off the casting.

[0033] Working principle: When using the heat treatment device for agricultural machinery castings, the casting is first placed in the placement rack 2 and then inserted into the heating box 1 for heat treatment. The rotating mechanism 3 facilitates the rotation of the casting to heat it from all directions. While the rotating mechanism 3 is rotating, the striking mechanism 4 continuously strikes the rotating mechanism 3 to cause the casting to vibrate, so as to shake off the debris generated after the surface is heated, thereby reducing the possibility of debris affecting the heat treatment of the casting.

[0034] The above description is a further detailed explanation of the present invention in conjunction with specific preferred embodiments, which is intended to enable those skilled in the art to understand and apply the present invention. However, it should not be assumed that the specific implementation of the present invention is limited to these descriptions.
