[0032] Based on the above solution, it is further preferred that: an assembly block is detachably installed in the delivery cavity by screws.

[0033] The beneficial effects of the present invention are:

[0034] 1. The present invention, by setting a conveying mechanism, can drive the conveying chain to run based on the work of the conveying drive motor, and then drive each conveying box to convey materials. During this period, the heating rod can heat the bottom of the conveying box, so as to achieve the effect of preheating the material; since the corrugated plate and the linkage frame are provided, and the position of the linkage frame is adapted to the corrugated plate, the linkage frame is periodically blocked by the wave crests of the corrugated plate during the movement of the conveying box, thereby causing structural deflection. After the linkage frame passes through the wave crests of the corrugated plate, the conveying box is driven to reset based on the rebound force of the clockwork spring, thus realizing the effect of continuously controlling the swing of the conveying box. Based on the swing of the conveying box, the posture of the material inside it can be adjusted, so that the material is heated more fully and evenly, thereby improving reliability.

[0035] 2. The present invention can oscillate while the conveying box is shaking by providing an annular elastic portion and a bottom plate, thereby better promoting heating of the material. In addition, since the annular elastic portion is an elastic structure, when there is too much material in the conveying box, the pressure on the bottom plate is naturally greater, resulting in a larger deformation of the annular elastic portion, so that it can be closer to the heating rod, thereby being more easily heated, thereby achieving the purpose of adaptive adjustment.

[0036] 3. The present invention provides a limiting frame and a limiting plate, which can block the limiting plate when the annular seat rotates, thereby limiting its deflection angle, preventing the conveying box from tipping over, and improving reliability.

[0037] 4. The present invention can reduce the resistance to movement of the structure when it contacts the corrugated plate by providing structures such as rollers, thereby ensuring the smooth operation of the device; by providing structures such as a box cover and an elastic rope, the elastic force of the elastic rope can be used to cause the box cover to close on the conveying box, so as to prevent the material from spilling due to shaking, thereby improving reliability.

[0038] 5. The present invention provides structures such as a linkage rod and a box cover 9. During the conveying process of the conveying box, since the end of the blocking rod is located on the moving path of the linkage rod, when the linkage rod contacts the blocking rod, the linkage rod can be blocked, thereby opening the box cover for easy unloading; as the conveying box continues to move, the elastic connecting part is deformed by force and finally detaches from the linkage rod, and the entire operation process has high reliability.

[0039] 6. The present invention can add materials to the feeding hopper by setting a feeding mechanism, and based on the operation of the rotating drive motor, drive the annular conveying seat to rotate in the baffle cover. During this period, the conveying chamber is periodically connected with the feeding port and the discharging port of the baffle cover. When the conveying chamber is connected with the feeding port of the baffle cover, the material can enter the conveying chamber, and when the conveying chamber is connected with the discharging port of the baffle cover, the material can be discharged from the discharging port.

[0040] 7. The present invention provides structures such as a cross frame and a limit plate. When the conveyor box moves below the discharge port, the limit plate can be used to block the linkage rod, thereby causing the box cover to deflect and open the cover. After the conveyor box is loaded with materials, as the conveyor chain continues to run, the conveyor box is continuously conveyed forward, thereby increasing the deflection angle of the box cover. When the deflection angle of the box cover increases to a certain extent, it can be separated from the limit plate and reset under the rebound force of the elastic rope, thereby realizing the function of automatic opening and closing of the cover with high reliability.

[0041] 8. The present invention can preheat the material in the conveying chamber by setting a heating component, thereby improving practicality; by setting an assembly block, the volume in the conveying chamber can be conveniently adjusted based on the installation quantity, thereby controlling the single loading amount, thereby improving practicality.

[0064] A linkage frame 15, the top of which is fixed to the bottom outer wall of the conveying box 12 by bolts, and the position of the linkage frame 15 is adapted to the corrugated plate 11;

[0065] By setting up a conveying mechanism, the conveying chain 2 can be driven to operate based on the operation of the conveying drive motor 10, and then each conveying box 12 can be driven to convey materials. During this period, the heating rod 17 can heat the bottom of the conveying box 12, so as to achieve the effect of preheating the material; since the corrugated plate 11 and the linkage frame 15 are provided, and the position of the linkage frame 15 is adapted to the corrugated plate 11, the linkage frame 15 is periodically blocked by the wave crests of the corrugated plate 11 during the movement of the conveying box 12, thereby causing structural deflection. After the linkage frame 15 passes through the wave crests of the corrugated plate 11, the conveying box 12 is reset based on the rebound force of the clockwork spring 14. In this way, the effect of continuously controlling the swing of the conveying box 12 is achieved. Based on the swing of the conveying box 12, the posture of the material inside it can be adjusted, so that the material is heated more fully and evenly, thereby improving reliability.

[0066] In order to better promote the shaking of materials; Figure 5 As shown, the bottom of the conveying box 12 is provided with an opening, the outer side of the opening is bonded with an annular elastic portion 19, and the bottom of the annular elastic portion 19 is bonded with a bottom plate 18;

[0067] By providing the annular elastic portion 19 and the bottom plate 18, the conveying box 12 can oscillate while shaking, thereby better promoting the heating of the material. In addition, since the annular elastic portion 19 is an elastic structure, when there is too much material in the conveying box 12, the pressure on the bottom plate 18 is naturally greater, resulting in a larger deformation of the annular elastic portion 19, so that it can be closer to the heating rod 17, thereby being more easily heated, thereby achieving the purpose of adaptive adjustment.

[0068] In order to limit the deflection angle of the conveyor box 12; Figure 6 As shown, an adjustment groove 23 is provided on the circumferential outer wall of the annular seat 26, an adjustment plate 24 is movably installed in the adjustment groove 23, and a fixing knob 25 for fixing the adjustment plate 24 is connected to the adjustment plate 24 through a thread; a limit plate 21 is integrally provided on the outer wall of one side of the adjustment plate 24;

[0071] In order to improve the smoothness of operation; Figure 4 As shown, a roller 16 is rotatably mounted on the bottom end of the linkage frame 15;

[0072] By providing structures such as rollers 16, the resistance to movement of the structure can be reduced when it contacts the corrugated plate 11, thereby ensuring smooth operation of the device.

[0073] To prevent the material from spilling due to shaking; as Figure 5 , Figure 7 shown, a lid 3 is hinged to the top of the conveying box 12, and one end of the lid 3 is fixed with an elastic cord 20 by screws, and one end of the elastic cord 20 is fixed to the conveying box 12 by screws;

[0074] By providing structures such as the lid 3 and the elastic cord 20, the elastic force of the elastic cord 20 can be utilized to urge the lid 3 to close on the conveying box 12, so as to prevent the material from spilling due to shaking and improve the reliability.

[0075] To facilitate discharging; as Figure 7 shown, a linkage rod 37 is fixed to the top of the lid 3 by bolts, and a side bracket 9 is fixed to the outer wall of one side of the mounting frame 1 by bolts. A stop rod 29 is fixed to the middle of the side bracket 9 by bolts. The stop rod 29 has a "丿" - shaped structure, and the end of the stop rod 29 is located on the moving path of the linkage rod 37. An elastic connecting part 30 capable of deforming is provided in the middle of the stop rod 29;

[0076] By providing structures such as the linkage rod 37 and the lid 39, during the process of conveying the conveying box 12, since the end of the stop rod 29 is located on the moving path of the linkage rod 37, when the linkage rod 37 contacts the stop rod 29, the linkage rod 37 can be blocked, thereby opening the lid 3 to facilitate discharging; as the conveying box 12 continues to move, the elastic connecting part 30 is deformed by force and finally disengages from the linkage rod 37, and the entire operation process has strong reliability.

[0077] Embodiment 2:

[0078] A chemical raw material conveying device, as Figure 1-9 shown, to facilitate quantitative feeding; the following improvements are made on the basis of Embodiment 1: The feeding mechanism includes:

During this period, the conveying chamber 35 is periodically connected with the feeding port and the discharging port of the baffle cover 5. When the conveying chamber 35 is connected with the feeding port of the baffle cover 5, the material can enter the conveying chamber 35. When the conveying chamber 35 is connected with the discharging port of the baffle cover 5, the material can be discharged from the discharging port.

After the conveying box 12 is loaded with materials, as the conveying chain 2 continues to run, the conveying box 12 is continuously conveyed forward, thereby increasing the deflection angle of the box cover 3. When the deflection angle of the box cover 3 increases to a certain extent, it can be separated from the limit plate 33 and reset under the rebound force of the elastic rope 20, thereby realizing the function of automatic opening and closing of the cover with high reliability.

[0089] In order to facilitate further heating; Figure 1 , Figure 8 As shown, a heating component 32 is installed on the outer wall of one side of the mounting frame 1 by bolts, and the heating component 32 extends into the center position of the annular conveying seat 31, and the annular conveying seat 31 is rotatably installed on the outer wall of the heating component 32;
