[0056] like Figures 1 to 13 As shown, the placement mechanism 2 is installed in the drying chamber 101, and the placement mechanism 2 is used to place agricultural and sideline products and Chinese medicinal materials.

[0057] The placement mechanism 2 includes two pairs of columns 201, which are fixedly connected to the drying chamber 101 and used to install a fixed support plate 202 and a plurality of movable support plates 205. A fixed support plate 202 is fixedly connected between each pair of columns 201, and the fixed support plate 202 is used to install the first tray 203.

[0058] In addition, a first tray 203 is slidably connected between the pair of fixed trays 202, and the agricultural and sideline products or Chinese medicinal materials on the first tray 203 are conveniently taken by slidingly connecting the first tray 203 and the fixed tray 202. A plurality of evenly distributed first through holes 2031 are provided through the bottom of the first tray 203, and drying gas can dry the agricultural and sideline products or Chinese medicinal materials in the first tray 203 through the surface of the first tray 203 or the first through holes 2031, so as to improve the drying efficiency and drying effect of the agricultural and sideline products or Chinese medicinal materials in the first tray 203.

[0059] Specifically, the fixed support plate 202 is threadedly connected with a first fastening bolt 204, and the first fastening bolt 204 corresponds to the first tray 203. The first fastening bolt 204 is used to fix the first tray 203 to prevent the first tray 203 from sliding between a pair of fixed support plates 202, so as to ensure that the agricultural and sideline products or Chinese medicinal materials in the first tray 203 can be stably dried.

[0060] like Figures 1 to 13 As shown, a number of adjustable trays are installed between the two pairs of columns 201. The adjustable trays are arranged at the lower side of the first tray 203. The adjustable trays can move up and down during the placement stage or the baking process to better dry the agricultural and sideline products or Chinese medicinal materials and avoid over-drying of some agricultural and sideline products or Chinese medicinal materials. At the same time, it can also greatly improve the drying efficiency of agricultural and sideline products and Chinese medicinal materials, and to a certain extent, it can also reduce the overall energy consumption of the drying room body 1.

[0061] The adjustable tray includes a pair of movable pallets 205 , which are movably disposed between a pair of columns 201 , and the movable pallets 205 are used to install a second tray 206 .

[0062] In addition, a plurality of second through holes 2061 are provided at the bottom of the second tray 206, and a gas collecting groove 2062 is provided at the bottom of the second tray 206, and the second through holes 2061 are connected to the gas collecting groove 2062. The drying gas discharged from the drying gas outlet 103 will enter the gas collecting groove 2062, and then enter the bottom of the second tray 206 through the second through holes 2061, and then be used to quickly dry the agricultural and sideline products or Chinese medicinal materials in the second tray 206.

[0063] Specifically, a second tray 206 is slidably connected between the pair of movable supporting plates 205 , and the second tray 206 is also used to place agricultural and sideline products or Chinese medicinal materials so as to dry the agricultural and sideline products or Chinese medicinal materials.

[0064] When placing agricultural and sideline products or Chinese medicinal materials, the agricultural and sideline products or Chinese medicinal materials that are easiest to dry are placed in the first tray 203, and the agricultural and sideline products or Chinese medicinal materials that take the longest time to dry are placed in the second tray 206 at the bottom.

[0065] In addition, a second fastening bolt 207 is threadedly connected to the movable support plate 205, and the second fastening bolt 207 corresponds to the second tray 206. The function of the second fastening bolt 207 is the same as that of the first fastening bolt 204, and both are used to play a fixing role to ensure that the second tray 206 will not shift when moving up and down, so that the agricultural and sideline products or Chinese medicinal materials in the second tray 206 can be stably dried.

[0066] like Figures 1 to 13 As shown, a mounting cavity 208 is provided in the movable support plate 205 , and a power supply, a controller and a servo motor 209 are installed in the mounting cavity 208 . The servo motor 209 is electrically connected to the power supply and the controller, and the servo motor 209 can be controlled and operated by the controller.

[0067] Preferably, the inner wall of the installation cavity 208 is provided with a heat-insulating material to prevent the power supply, the controller and the servo motor 209 from being affected by high temperature, so as to ensure that the power supply, the controller and the servo motor 209 can operate safely and stably.

[0068] The output end of the servo motor 209 is connected to a rotating gear 210. When the servo motor 209 is running, the rotating gear 210 can rotate. A rack 211 is connected to one of the columns 201, and the rack 211 meshes with the rotating gear 210. When the rotating gear 210 rotates, due to the meshing action of the rotating gear 210 and the rack 211, the movable support plate 205 can move between a pair of columns 201.

[0069] In addition, an electric cylinder 212 is installed in the installation cavity 208, and a fixing pin 213 is connected to the free end of the electric cylinder 212. A plurality of evenly distributed engaging holes 214 are provided on the side wall of one of the columns 201, and one end of the fixing pin 213 is inserted into the engaging hole 214. When the electric cylinder 212 is extended, the fixing pin 213 can be inserted into the engaging hole 214, so as to fix the moving position of the moving pallet 205 and prevent the moving pallet 205 from falling from the column 201.

[0071] Specifically, a displacement sensor 215 and an inductor are installed on the movable pallet 205, and the displacement sensor 215 is electrically connected to the power supply and the controller. The displacement sensor 215 is used to monitor the distance between the upper and lower pairs of movable pallets 205 to avoid collision when the upper and lower pairs of movable pallets 205 move, thereby ensuring overall operational safety. The inductor is used to monitor the blocking bar 302 to determine the falling height of the blocking bar 302 so that the unfolded blocking bar 302 can cover the dried agricultural and sideline products or Chinese medicinal materials.

[0072] like Figures 1 to 13 As shown, a mounting groove 2032 is provided on one side of the first tray 203 close to the drying chamber 101 , and the mounting groove 2032 is used for mounting the housing 3 .

[0073] Among them, the housing 3 is installed in the installation groove 2032, and the housing 3 is used to accommodate the blocking bar 302. The housing 3 is rotatably connected with a rotating shaft 301, and the rotating shaft 301 is used to wind the blocking bar 302. The rotating shaft 301 is connected with a winding motor, and the blocking bar 302 is wound on the rotating shaft 301, and one end of the blocking bar 302 passes through the housing 3. The blocking bar 302 is used to block the drying gas, so as to prevent the drying gas from further drying the dried agricultural and sideline products or Chinese medicinal materials, and to prevent the agricultural and sideline products or Chinese medicinal materials from being over-dried, so as to ensure the drying quality of the agricultural and sideline products or Chinese medicinal materials.

[0074] Preferably, the blocking strip 302 is made of a high temperature resistant material, such as a rubber strip, to prevent the blocking strip 302 from being affected by the high temperature drying gas, thereby ensuring the service life of the blocking strip 302 .

[0075] In addition, a counterweight is connected to one end of the blocking bar 302 away from the rotating shaft 301, and the counterweight corresponds to the sensor. When the blocking bar 302 is released, the counterweight makes the blocking bar 302 in a tight state and pulls the blocking bar 302 to expand, so that the blocking bar 302 can cover one side of the plurality of second trays 206, that is, Figure 8In the state shown, the drying gas is prevented from further drying the dried agricultural and sideline products or Chinese medicinal materials, thereby ensuring the drying quality of the agricultural and sideline products or Chinese medicinal materials. At the same time, the drying gas can also be guided to move downward to dry the agricultural and sideline products or Chinese medicinal materials in the lower second tray 206.

[0076] At the same time, the position of the counterweight block can be determined by using a sensor to ensure that the blocking bar 302 can correctly cover one side of the second tray 206 .

[0079] S2. When adjusting the position of the second pallet 206, firstly control the pair of electric cylinders 212 to contract synchronously, so that the fixing pin 213 is disengaged from the engagement hole 214, and then synchronously operate the pair of servo motors 209, the servo motors 209 drive the rotating gear 210 to rotate, and since the rotating gear 210 is meshed with the rack 211, when the rotating gear 210 rotates, the movable pallet 205 and the second pallet 206 can move along the column 201, so as to adjust the position of the second pallet 206;

[0080] S3, when the position of the second tray 206 is adjusted, the servo motor 209 is stopped, and the pair of electric cylinders 212 are controlled to extend so that the fixing pins 213 are reinserted into the corresponding engaging holes 214 to fix the position of the second tray 206;

[0081] S4, placing the agricultural and sideline products and Chinese medicinal materials that are easy to dry in the first tray 203 and the second tray 206 from top to bottom according to the degree of easy drying, that is, the agricultural and sideline products or Chinese medicinal materials in the first tray 203 have the shortest drying time, and the agricultural and sideline products or Chinese medicinal materials in the second tray 206 at the bottom have the longest drying time, closing the cover door 102, and operating the drying equipment in the drying room body 1, and the drying gas generated by the drying equipment enters the drying chamber 101 through the drying gas outlet 103, and the agricultural and sideline products and Chinese medicinal materials in the first tray 203 and the second tray 206 are dried;

[0082] S5, drying stage: the drying gas in the drying chamber 101 passes through the surface of the first tray 203 and the first through hole 2031 to dry the agricultural and sideline products or Chinese medicinal materials in the first tray 203, and the drying gas in the drying chamber 101 passes through the surface of the second tray 206 and the gas collecting groove 2062 and the second through hole 2061 to dry the agricultural and sideline products or Chinese medicinal materials in the second tray 206;

[0083] S6. If the agricultural and sideline products or Chinese medicinal materials in the first tray 203 or part of the upper second tray 206 are dried, the position of the second tray 206 can be adjusted upward, so that the dried agricultural and sideline products or Chinese medicinal materials are moved upward, so as to expand space for the agricultural and sideline products or Chinese medicinal materials that are not fully dried in the lower second tray 206, so as to speed up the drying efficiency of the agricultural and sideline products or Chinese medicinal materials in the lower second tray 206;

[0084] S7. At the same time, the winding motor drives the rotating shaft 301 to rotate, so that the rotating shaft 301 releases the blocking bar 302. The blocking bar 302 is released from the housing 3 under the action of the counterweight block. The counterweight block and the sensor cooperate with each other to determine the falling position of the counterweight block, so that the unfolded blocking bar 302 can cover one side of the second tray 206, that is, it is used to block the drying gas from passing through the surface of the second tray 206 or through the gas collecting groove 2062 and the second through hole 2061 to further dry the agricultural and sideline products or Chinese medicinal materials dried in the second tray 206, so as to avoid excessive drying of the agricultural and sideline products or Chinese medicinal materials and ensure the drying quality of the agricultural and sideline products or Chinese medicinal materials. The drying gas blocked by the blocking bar 302 will move to the upper and lower sides along the blocking bar 302. When the drying gas passes through the lower second tray 206, the drying efficiency of the agricultural and sideline products or Chinese medicinal materials in the lower second tray 206 can be increased.

[0085] S8. When all the agricultural and sideline products or Chinese medicinal materials in the second tray 206 are dried, the drying equipment is turned off, the cover door 102 is opened, and the agricultural and sideline products and Chinese medicinal materials are taken out.

10. A method for using the baking device for primary processing of agricultural and sideline products and Chinese medicinal materials as claimed in any one of claims 1 to 9, characterized in that: The following steps are involved: S1, placement stage: open the cover door, and adjust the positions of several second trays on the pillars to facilitate the placement of agricultural and sideline products and Chinese medicinal materials; S2. When adjusting the position of the second pallet, first control a pair of electric cylinders to contract synchronously so that the fixing pins are disengaged from the engaging holes, and then synchronously operate a pair of servo motors, which drive the rotating gears to rotate. Since the rotating gears are meshed with the racks, when the rotating gears rotate, the movable pallet and the second pallet can move along the column to adjust the position of the second pallet. S3. When the position of the second pallet is adjusted, the servo motor is stopped, and a pair of electric cylinders are controlled to extend so that the fixing pins are reinserted into the corresponding engaging holes to fix the position of the second pallet; S4. Place the agricultural and sideline products and Chinese medicinal materials that are easy to dry in the first tray and the second tray in order from top to bottom according to the degree of easy drying. That is, the agricultural and sideline products or Chinese medicinal materials in the first tray have the shortest drying time, and the agricultural and sideline products or Chinese medicinal materials in the second tray at the bottom have the longest drying time. Close the cover door and dry the agricultural and sideline products and Chinese medicinal materials in the first tray and the second tray; S5, drying stage: the drying gas in the drying chamber passes through the surface of the first tray and the first through hole to dry the agricultural and sideline products or Chinese medicinal materials in the first tray, and the drying gas in the drying chamber passes through the surface of the second tray and the gas collecting groove and the second through hole to dry the agricultural and sideline products or Chinese medicinal materials in the second tray; S6. If the agricultural and sideline products or Chinese medicinal materials in the first tray or part of the upper second tray are dried, adjust the position of the corresponding second tray so that the dried agricultural and sideline products or Chinese medicinal materials move upward, so as to expand space for the agricultural and sideline products or Chinese medicinal materials that are not fully dried in the lower second tray, so as to speed up the drying efficiency of the agricultural and sideline products or Chinese medicinal materials in the lower second tray; S7. At the same time, the winding motor drives the rotating shaft to rotate, so that the rotating shaft releases the blocking bar, and the blocking bar is released from the shell under the action of the counterweight block. Through the cooperation between the counterweight block and the sensor, the unfolded blocking bar can block the drying gas from further drying the agricultural and sideline products or Chinese medicinal materials in the second tray that have been dried. The drying gas blocked by the blocking bar will move along the blocking bar to the upper and lower sides, and pass through the lower second tray to increase the drying efficiency of the agricultural and sideline products or Chinese medicinal materials in the lower second tray; S8. When all agricultural and sideline products or Chinese medicinal materials in the second tray are dried, open the cover door and take out the agricultural and sideline products and Chinese medicinal materials.
