Specifically, the first motor 14 drives the third gear 15 rotates, the third gear 15 drives the second gear 13 to rotate so that the support shaft 29 rotates, and when the support shaft 29 rotates, it drives the half gear 12 thereon to rotate. When the teeth of the upper half gear 12 are engaged with the teeth on the upper side of the second rack 11, the teeth of the lower half gear 12 are disengaged from the teeth on the lower side of the second rack 11. As the upper half gear 12 rotates, the second rack 11 is driven to move. When the teeth of the upper half gear 12 are disengaged from the teeth on the lower side of the second rack 11, the teeth of the lower half gear 12 are engaged with the teeth on the lower side of the second rack 11.

[0024] In this embodiment, several adjustment shafts 5 are located at one end of the outside of the adjustment box 2 and are fixedly sleeved with a toothed belt pulley 7, and a synchronous toothed belt 8 is wound around the several toothed belt pulleys 7. Specifically, the synchronous toothed belt 8 drives other toothed belt pulleys 7 to rotate, so that multiple adjustment shafts 5 rotate at the same time.

[0025] In this embodiment, the right outer surface of the adjustment box 2 is fixedly connected to the first slide rod, and the outer surface of the second rack 11 is fixedly connected to a slide plate, which is movably mounted on the outer surface of the first slide rod. Specifically, when the second rack 11 moves, the slide plate is driven to slide on the outer surface of the first slide rod, thereby making the second rack 11 move stably in a straight line.

[0026] In the specific implementation process, the heat generated by the industrial heat pump body 3 is transported to the regulating box 2, and the wind force is generated by the fan 16 to the disc 17, and the heat is blown to the inside of the drying box 1 to dry the material inside the drying box 1. At this time, the first motor 14 works, the first motor 14 drives the third gear 15 to rotate, and the third gear 15 drives the second gear 13 to rotate so that the support shaft 29 rotates. When the support shaft 29 rotates, it drives the half gear 12 thereon to rotate. When the teeth of the upper half gear 12 are engaged with the teeth above the second rack 11, the teeth of the lower half gear 12 are disengaged from the teeth below the second rack 11. As the upper half gear 12 rotates, the second rack 11 is driven to move. When the teeth of the upper half gear 12 are disengaged from the teeth below the second rack 11, the lower half gear 12 is disengaged from the teeth below the second rack 11.

As the lower half gear 12 rotates, the second rack 11 is driven to move to the other side, so that as the first motor 14 works, the second rack 11 is driven to reciprocate. When the second rack 11 moves, it drives the first rack 10 to reciprocate. When the first rack 10 moves, it drives the first gear 9 to reciprocate. The first gear 9 drives its corresponding adjustment shaft 5 to rotate, and makes the toothed belt wheel 7 thereon rotate. Under the action of the synchronous toothed belt 8, it drives other toothed belt wheels 7 to rotate, so that multiple adjustment shafts 5 rotate at the same time, so as to adjust the inclination direction of the guide plate 6.

[0027] Embodiment 2: Please refer to Figure 3 and Figure 6-Figure 9 The present invention provides a technical solution: two side panels 18 are arranged inside the drying box 1, and a central axis is rotatably connected between the two side panels 18. A second motor 19 is fixedly installed on the rear outer surface of the rear side panel 18, and the output end of the second motor 19 is fixedly connected to the central axis. Two cross plates 20 are fixedly sleeved on the outer surface of the central axis, and four transverse axes 21 are fixedly connected between the two cross plates 20. The outer surfaces of the four transverse axes 21 are rotatably connected to two rotating rods 22, and the bottom outer surfaces of the two rotating rods 22 are fixedly connected to a material holding frame 23. Specifically, when the second motor 19 is working, the second motor 19 drives the central axis to rotate, and when the central axis rotates, the cross plate 20 thereon is driven to rotate. When the cross plate 20 rotates, the material holding frame 23 is rotated. During the rotation process, the material holding frame 23 always remains in a vertical downward state, so that during the drying process, the material can be rotated, thereby further improving the drying effect.

[0028] In the present embodiment, the bottom of the material holding frame 23 is hollow, and an elastic net is arranged at the hollow part of the bottom of the material holding frame 23. Two electric push rods 24 are fixedly installed on the outer surface of the bottom of the material holding frame 23. The output ends of the two electric push rods 24 are fixedly connected with mounting plates, and a rotating shaft 26 is rotatably connected between the two mounting plates. A motor 25 is fixedly installed on the outer surface of the rear mounting plate, and the output end of the motor 25 is fixedly connected with the rotating shaft 26. The outer surface of the rotating shaft 26 is fixedly sleeved with a plurality of eccentric wheels 27. Specifically, when the material is scattered parts, the electric push rod 24 is turned on, and the electric push rod 24 works so that the eccentric wheel 27 contacts with the elastic net and causes the elastic net to deform to a certain extent. Then the motor 25 works, and the motor 25 drives the rotating shaft 26 to rotate, and the rotating shaft 26 drives the eccentric wheel 27 to rotate, so that the eccentric wheel 27 produces elastic deformation on the elastic net. With the operation of the motor 25, the material in the material holding frame 23 changes dynamically, so as to avoid the stacking of scattered materials and the existence of drying dead corners, thereby improving the drying effect.

[0029] In this embodiment, the four corners of the bottom of the material holding frame 23 are fixedly connected with counterweight blocks. Specifically, under the action of the counterweight blocks, the material holding frame 23 is kept in a vertical downward state at all times.

[0030] In the specific implementation process, before drying the material, the box door is opened, the material is placed in the material holding frame 23, and the second motor 19 is working. The second motor 19 drives the central axis to rotate. When the central axis rotates, it drives the cross plate 20 thereon to rotate. When the cross plate 20 rotates, the material holding frame 23 rotates. During the rotation process, the material holding frame 23 always remains in a vertical downward state, so that during the drying process, the material can rotate, further improving the drying effect. When the material is scattered parts, the electric push rod 24 is turned on, and the electric push rod 24 works to make the eccentric wheel 27 contact with the elastic net and make the elastic net deform to a certain extent. Then the motor 25 works, and the motor 25 drives the rotating shaft 26 to rotate. The rotating shaft 26 drives the eccentric wheel 27 to rotate, so that the eccentric wheel 27 produces elastic deformation on the elastic net. With the operation of the motor 25, the material in the material holding frame 23 changes dynamically, avoiding the stacking of scattered materials and the existence of drying dead corners, thereby improving the drying effect.

[0031] Embodiment 3: Please refer to Figure 3 and Figure 6-Figure 7The present invention provides a technical solution: the left and right inner surfaces of the drying box 1 are rotatably connected with support shafts 29, the right support shaft 29 rotates and penetrates the right outer surface of the drying box 1, and one end of the right support shaft 29 located outside the drying box 1 is fixedly connected with a crank 34, and the outer surfaces of the two support shafts 29 are fixedly sleeved with fourth gears 30, and the left and right outer surfaces of the two side plates 18 are fixedly connected with third racks 28, and the two fourth gears 30 are movably meshed with the outer surfaces of the two third racks 28 respectively. Specifically, by rotating the crank 34, the crank 34 drives the support shaft 29 to rotate, the support shaft 29 drives the fourth gear 30 to rotate, and the fourth gear 30 drives the third rack 28 to move, so that the material holding frame 23 extends out of the drying box 1, thereby facilitating the placement of materials in the material holding frame 23 or taking them out of the material holding frame 23.

[0032] In this embodiment, a transmission shaft 31 is rotatably connected between the inner walls of the left and right sides of the drying box 1. The outer surfaces of the transmission shaft 31 and the outer surfaces of the two support shafts 29 are fixedly sleeved with sprockets 32. There are two sprockets 32 on the outer surface of the transmission shaft 31, and a chain 33 is meshed and wound around the upper and lower sprockets 32. Specifically, when the support shaft 29 rotates, the sprocket 32 ​​thereon is driven to rotate. Under the action of the chain 33, the sprocket 32 ​​on the transmission shaft 31 is driven to rotate, thereby causing the transmission shaft 31 to rotate. Under the action of another set of sprockets 32 and the chain 33, the two support shafts 29 rotate at the same time.

[0033] In this embodiment, two second sliding rods are fixedly connected to the interior of the drying box 1, and the outer surfaces of the two third racks 28 are fixedly connected with sliders, and the two sliders are movably mounted on the outer surfaces of the two second sliding rods. Specifically, when the third rack 28 moves, it drives the slider to slide on the outer surface of the second sliding rod, so that the third rack 28 can move stably in a straight line.

[0034] During the specific implementation process, before and after the material is dried, the box door is opened and the crank 34 is turned. The crank 34 drives the support shaft 29 on the right to rotate, and the sprocket 32 ​​thereon rotates. When the sprocket 32 ​​rotates, it drives the sprocket 32 ​​on the transmission shaft 31 to rotate under the action of the chain 33, and then drives another support shaft 29 to rotate under the action of another set of sprockets 32 and chains 33, so that the two fourth gears 30 rotate at the same time. When the fourth gear 30 rotates, it drives the third rack 28 to move, so that the material frame 23 extends out of the drying box 1, thereby facilitating the placement of materials in the material frame 23 or taking them out of the material frame 23.

[0035] Working principle: In actual use, the present invention generates heat through the industrial heat pump body 3 and transmits it to the regulating box 2, and generates wind force to the disc 17 through the operation of the fan 16, and blows the heat to the inside of the drying box 1 to dry the material inside the drying box 1. At this time, the first motor 14 works, the first motor 14 drives the third gear 15 to rotate, and the third gear 15 drives the second gear 13 to rotate so that the support shaft 29 rotates. When the support shaft 29 rotates, it drives the half gear 12 thereon to rotate. When the teeth of the upper half gear 12 are engaged with the teeth above the second rack 11, the teeth of the lower half gear 12 are disengaged from the teeth below the second rack 11. As the upper half gear 12 rotates, the second rack 11 is driven to move. When the teeth of the upper half gear 12 are disengaged from the teeth below the second rack 11, At this time, the teeth of the lower half gear 12 are meshed with the teeth below the second rack 11. As the lower half gear 12 rotates, the second rack 11 is driven to move to the other side, so that as the first motor 14 works, the second rack 11 is driven to reciprocate. When the second rack 11 moves, it drives the first rack 10 to reciprocate. When the first rack 10 moves, it drives the first gear 9 to reciprocate. The first gear 9 drives its corresponding adjustment shaft 5 to rotate, and makes the toothed belt wheel 7 thereon rotate. Under the action of the synchronous toothed belt 8, it drives other toothed belt wheels 7 to rotate, so that multiple adjustment shafts 5 rotate at the same time, so as to adjust the inclination direction of the guide plate 6, and the hot air is blown into the drying box 1 through the guide of the guide plate 6 to dry the material inside, so that the hot air can be evenly blown into the drying box 1 from all directions to improve the drying effect.

[0036] Before drying the material, the box door is opened, and the material is placed in the material holding frame 23. The second motor 19 works, and the second motor 19 drives the central shaft to rotate. When the central shaft rotates, it drives the cross plate 20 thereon to rotate. When the cross plate 20 rotates, the material holding frame 23 rotates. During the rotation process, the material holding frame 23 always remains in a vertical downward state, so that during the drying process, the material can rotate, further improving the drying effect. When the material is scattered parts, the electric push rod 24 is turned on, and the electric push rod 24 works to make the eccentric wheel 27 contact with the elastic net and make the elastic net deform to a certain extent. Then the motor 25 works, and the motor 25 drives the rotating shaft 26 to rotate. The rotating shaft 26 drives the eccentric wheel 27 to rotate, so that the eccentric wheel 27 produces elastic deformation on the elastic net. With the operation of the motor 25, the material in the material holding frame 23 changes dynamically, avoiding the stacking of scattered materials and the existence of drying dead corners, thereby improving the drying effect.

[0037] Before and after the material is dried, the box door is opened and the crank 34 is turned. The crank 34 drives the support shaft 29 on the right to rotate, and the sprocket 32 ​​thereon rotates. When the sprocket 32 ​​rotates, it drives the sprocket 32 ​​on the transmission shaft 31 to rotate under the action of the chain 33, and then drives the other support shaft 29 to rotate under the action of another set of sprockets 32 and chains 33, so that the two fourth gears 30 rotate at the same time. When the fourth gear 30 rotates, it drives the third rack 28 to move, so that the material holding frame 23 extends out of the drying box 1, so as to facilitate the placement of materials in the material holding frame 23 or taking them out of the material holding frame 23.
