Description

Technical Field

[0001] The utility model relates to the technical field of heat pump dryer accessories, in particular to an auxiliary bracket for a heat pump dryer. Background Art

[0002] Edible fungi are now widely used, and edible fungi usually need to be dried during processing. Coal-fired boilers are usually used for drying, but this method is highly polluting. At the same time, it is difficult to maintain uniformity when drying a large number of edible fungi at the same time. Often some edible fungi are not dried, so it is difficult to meet social needs.

[0003] For example, the utility model with announcement number CN219433755U discloses an auxiliary bracket for an energy-saving heat pump dryer, including a bracket, a tray and a tilt adjustment mechanism. The utility model provides a tilt adjustment mechanism on the bracket and the tray, and can adjust the tilt of the tray accordingly according to the position of the bracket. If the bracket is close to the heat source, the tilt of the tray can be adjusted to a smaller angle to prevent the tray at this position from blocking the hot air flow, thereby affecting the drying effect of the subsequent materials. If the bracket is far from the heat source, the tilt of the tray can be adjusted to a larger angle to enable the tray at this position to be exposed to more hot air flow, thereby ensuring the drying effect. By providing a baffle on the inner side of the tray, the baffle acts as a separator for the materials in the tray, thereby preventing all the materials from piling up at a low place after the tray is tilted, which is not conducive to drying.

[0004] In the process of implementing this application, it was found that the technology has the following problems: when using the auxiliary bracket for the existing energy-saving heat pump dryer, the bottom of most of the dried items are attached to the bottom of the inner wall of the bracket, so that when the upper surface of the dried items is dried, the lower surface does not reach the expected drying speed, which causes the auxiliary bracket to dry the items slowly during long-term use, thereby reducing the practicality of the equipment.

[0005] For this reason, an auxiliary bracket for a heat pump drying machine is proposed. Utility Model Content

A driving mechanism 4 for driving the three groups of U-shaped ventilation boxes 3 to turn over is provided on the side of the U-shaped bracket body 1 away from the three groups of through holes. A protective mechanism 6 is installed on the side of the main body 1 close to the driving mechanism 4, and slots are provided on the front and rear sides of the three groups of U-shaped turning frames 2, and positioning mechanisms 5 are provided on the front and rear sides of the three groups of U-shaped turning frames 2; specifically, the driving mechanism 4 is inductively triggered to start the flipping of the positions of the three groups of U-shaped ventilation boxes 3, so that the staff does not need to manually flip the positions of the three groups of U-shaped ventilation boxes 3 when using the auxiliary bracket to dry the items, thereby shortening the time and labor consumed in the subsequent drying of the items by the auxiliary bracket, thereby improving the practicality of the auxiliary bracket during use.

[0027] like Figure 1 and Figure 2As shown, the driving mechanism 4 includes a gear 1 401, a fixing rod 404, a temperature detector 410, a motor 408 and a control panel 409. A groove is provided on the side of the U-shaped bracket body 1 away from the three groups of U-shaped flip frames 2. The fixing rod 404 is rotatably connected to the inside of the groove of the U-shaped bracket body 1. The gear 1 401 is installed on one end of the fixing rod 404 close to the three groups of U-shaped flip frames 2. The external teeth of the gear 1 401 are meshed and connected with a toothed belt 402. The internal teeth of the toothed belt 402 are meshed and connected with two groups of gears 2 403. Two groups of slots are provided on the inner wall of the side of the U-shaped bracket body 1 close to the gear 1 401. The two groups of gears 2 403 are rotatably connected to the inside of the two groups of slots of the U-shaped bracket body 1 on the sides away from the three groups of U-shaped flip frames 2. The two groups of gears 2 403 and the gear 1 401 are away from the U-shaped bracket body. 1 is provided with positioning rods 407 on one side of the inner wall of the U-shaped bracket body 1, and the three groups of positioning rods 407 are respectively installed on the side of the three groups of U-shaped turning frames 2 close to the gear one 401 on the side away from the inner wall of the U-shaped bracket body 1, and the outer surfaces of the three groups of fixing rods 404 are installed with gear three 405, and the motor 408 and the control panel 409 are both installed on the side of the U-shaped bracket body 1 close to the gear three 405, and the outer teeth of the gear three 405 are meshed and connected with the gear four 406, and the output shaft of the motor 408 is installed on the side of the gear four 406 close to the U-shaped bracket body 1, and the temperature detector 410 is installed on the upper surface of a group of U-shaped turning frames 2 in the middle, and the detection end of the temperature detector 410 is attached to the top of the inner wall of the U-shaped turning frame 2, and the output end of the temperature detector 410 is electrically connected between the control panel 409 and the control end of the motor 408;

[0028] Specifically, the detection end of the temperature detector 410 is located at the top of the inner wall of the U-shaped turning frame 2, so that the temperature detector 410 detects the temperature of the upper surface of the dried articles in the middle group of U-shaped ventilation boxes 3 during use. When the temperature of the upper surface of the dried articles in the middle group of U-shaped ventilation boxes 3 reaches the preset value set by the temperature detector 410, the subsequent temperature detector 410 triggers the control panel 409 to start the motor 408, and then the gear 406 is installed on the output shaft of the motor 408, so that the subsequent motor 408 drives the gear 3 405, the toothed belt 402, the gear 1 401 and the two groups in the process of rotation. The gear 2 403 rotates, and the two groups of gears 2 403 and gear 1 401 drive the three groups of positioning rods 407, the three groups of U-shaped flip frames 2 and the three groups of U-shaped ventilation boxes 3 to flip during the rotation, so that the subsequent drying objects can be dried on both sides when placed inside the auxiliary bracket, thereby improving the practicality of the auxiliary bracket during use; the positions of the three groups of U-shaped ventilation boxes 3 are flipped by the driving mechanism 4 inductively triggered, so that the staff does not need to manually flip the positions of the three groups of U-shaped ventilation boxes 3 when using the auxiliary bracket to dry the objects, thereby shortening the time and labor consumed by the auxiliary bracket for drying the objects.

[0029] like Figure 3 As shown, two groups of partition plates 7 are installed at the bottom of the inner walls of the three groups of U-shaped ventilation boxes 3; specifically, the internal storage space of the U-shaped ventilation box 3 is divided by the two groups of partition plates 7, so that after the subsequent U-shaped ventilation box 3 is flipped over, the dried items placed inside the U-shaped ventilation box 3 are piled up on one side inside the U-shaped ventilation box 3, thereby minimizing the possibility that the items placed inside the subsequent U-shaped ventilation box 3 cannot be dried.

[0030] like Figure 1 and Figure 2 As shown, the protection mechanism 6 includes a U-shaped insulation board 601, which is installed on one side of the U-shaped bracket body 1 close to the gear three 405, and the control panel 409 and the motor 408 are both located inside the U-shaped insulation board 601; specifically, the U-shaped insulation board 601 is set at the outer end of the motor 408 and the control panel 409, and the U-shaped insulation board 601 has the characteristics of heat preservation and heat insulation, so that the U-shaped insulation board 601 blocks the internal heat flow of the heat pump dryer from contacting the motor 408 and the control panel 409, and then the U-shaped insulation board 601 blocks the motor 408 and the control panel 409 on one side of the U-shaped bracket body 1 for shielding and protection, thereby avoiding the motor 408 and the control panel 409 from contacting the internal heat flow of the heat pump dryer for a long time during subsequent use, thereby preventing the motor 408 and the control panel 409 from being damaged.

[0031] like Figure 1 and Figure 2 As shown, a groove is provided on the upper surface of the U-shaped heat insulation board 601, and a ventilation fan 603 is installed inside the groove of the U-shaped heat insulation board 601. A bellows 602 is provided on the upper surface of the U-shaped heat insulation board 601, and the ventilation fan 603 is located inside the exhaust end of the bellows 602. The end of the bellows 602 away from the U-shaped heat insulation board 601 is installed inside the air inlet hole of the heat pump dryer; specifically, the air inlet end of the bellows 602 is installed inside the air inlet hole of the heat pump dryer, so that subsequent staff can start the ventilation fan 603 to guide the external air of the heat pump dryer along the bellows 602 to the inside of the U-shaped heat insulation board 601, so that the internal air of the U-shaped heat insulation board 601 can keep circulating during use, thereby minimizing the failure of the subsequent motor 408 to dissipate heat during use and causing damage to the motor 408.

[0032] like Figure 1 , Figure 2 and Figure 4As shown, the six groups of positioning mechanisms 5 all include L-shaped positioning blocks 501 and magnetic blocks 502. The six groups of magnetic blocks 502 are respectively installed on the inner wall of the two groups of slots inside the three groups of U-shaped flip frames 2 away from the side of the gear 401. The six groups of L-shaped positioning blocks 501 are respectively slidably connected to the six groups of grooves of the three groups of U-shaped flip frames 2. The positions of the six groups of magnetic blocks 502 are respectively located on the moving paths of the six groups of L-shaped positioning blocks 501. The inner walls of the six groups of L-shaped positioning blocks 501 are respectively abutted against the front and rear sides of the three groups of U-shaped ventilation boxes 3. Specifically, the six groups of L-shaped positioning blocks 501 are respectively abutted against the front and rear sides of the three groups of U-shaped ventilation boxes 3 by the inner walls of the six groups of L-shaped positioning blocks 501. The sliding positions of the three groups of U-shaped ventilation boxes 3 inside the three groups of U-shaped flip frames 2 are restricted, so as to avoid the subsequent three groups of U-shaped ventilation boxes 3 from sliding inside the three groups of U-shaped flip frames 2 during the flipping process, thereby improving the stability of the three groups of U-shaped ventilation boxes 3 during use; by pushing the six groups of L-shaped positioning blocks 501 to move, the inner side walls of the six groups of L-shaped positioning blocks 501 are respectively adsorbed on one side of the six groups of magnetic blocks 502, so that the six groups of magnetic blocks 502 limit the positions of the six groups of L-shaped positioning blocks 501 inside the two groups of slots of the three groups of U-shaped ventilation boxes 3, so as to avoid the subsequent six groups of L-shaped positioning blocks 501 from moving during use.

[0033] In summary: the detection end of the temperature detector 410 is located at the top of the inner wall of the U-shaped turning frame 2, so that the temperature detector 410 detects the temperature of the upper surface of the dried articles in the middle group of U-shaped ventilation boxes 3 during use. When the temperature of the upper surface of the dried articles in the middle group of U-shaped ventilation boxes 3 reaches the preset value set by the temperature detector 410, the subsequent temperature detector 410 triggers the control panel 409 to start the motor 408, and then the gear four 406 is installed on the output shaft of the motor 408, so that the subsequent motor 408 drives the gear three 405, the toothed belt 402, The gear 1 401 and the two sets of gear 2 403 rotate, so that the two sets of gear 2 403 and the gear 1 401 drive the three sets of positioning rods 407, the three sets of U-shaped flip frames 2 and the three sets of U-shaped ventilation boxes 3 to flip during the rotation, so that the subsequent dried items can be dried on both sides when placed inside the auxiliary bracket; the internal storage space of the U-shaped ventilation box 3 is divided by the two sets of partition plates 7, so that after the subsequent U-shaped ventilation box 3 is flipped, the dried items placed inside the U-shaped ventilation box 3 are accumulated on one side inside the U-shaped ventilation box 3, so as to avoid as much as possible that the subsequent items placed inside the U-shaped ventilation box 3 cannot be dried.

[0034] At the same time, the U-shaped heat insulation board 601 is arranged at the outer end of the motor 408 and the control panel 409, and the U-shaped heat insulation board 601 has the characteristics of heat preservation and heat insulation, so that the U-shaped heat insulation board 601 blocks the internal heat flow of the heat pump dryer from contacting the motor 408 and the control panel 409, and then the U-shaped heat insulation board 601 shields and protects the motor 408 and the control panel 409 on one side of the U-shaped bracket body 1, thereby avoiding the subsequent motor 408 and the control panel 409 from being in contact with the heat pump dryer for a long time during use. The heat flow inside the machine comes into contact and causes damage to the motor 408 and the control panel 409; the air inlet end of the bellows 602 is installed inside the air inlet hole of the heat pump dryer, so that the subsequent staff can start the ventilation fan 603 to guide the external air of the heat pump dryer along the bellows 602 to the inside of the U-shaped insulation board 601, so that the internal air of the U-shaped insulation board 601 can be kept circulating during use, thereby minimizing the damage to the motor 408 caused by the failure of subsequent heat dissipation during use.
