DETAILED DESCRIPTION
[0018] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively and carefully below in conjunction with the accompanying drawings and preferred embodiments of the specification, but the protection scope of the present invention is not limited to the following specific embodiments.
[0019] It should be noted that when an element is described as being "fixed, fixed, connected or connected to" another element, it can be directly fixed, fixed, connected or connected to the other element, or it can be indirectly fixed, fixed, connected or connected to the other element through other intermediate connectors.
[0020] Unless otherwise defined, all professional terms used below have the same meanings as those generally understood by those skilled in the art. The professional terms used herein are only for the purpose of describing specific embodiments and are not intended to limit the scope of protection of the present utility model. Example
[0021] The multi-stage melon seed drying machine in this embodiment can perform graded drying of melon seeds at different temperatures, thereby preventing the melon seeds from being over-dried or not having enough moisture. Figure 1 and Figure 4 As shown, the multi-stage melon seed dryer in this embodiment includes three drying boxes 100, and a conveying device 200 and a heating device are arranged in the drying box 100. The feed end and the discharge end of the conveying device 200 extend out of the drying box 100, and the heating device is arranged above the conveying device 200; a lifting device 300 is arranged between two adjacent conveying devices 200, and the feed end of the lifting device 300 is located below the discharge end of the upper-stage conveying device 200, and the discharge end of the lifting device 300 is located above the feed end of the lower-stage conveying device 200.
[0022] like Figure 1 As shown, in this embodiment, the conveying direction of the melon seeds is from left to right. The melon seeds are first placed on the feeding end of the first-stage conveying device 200 and then conveyed to the first-stage drying box 100. Because the melon seeds contain the highest moisture when they are initially dried, the temperature set by the heating device in the first-stage drying box 100 is the highest, so that most of the moisture in the melon seeds can be dried and removed; after being dried in the first-stage drying box 100, the melon seeds fall from the discharging end of the first-stage conveying device 200 to the feeding end of the first-stage lifting device 300, and the melon seeds can be temporarily stored on the first-stage lifting device 300 for feeding. The melon seeds are then transported to the second drying box 100 through the second conveying device 200. In order to prevent the melon seeds from being over-dried, the temperature of the heating device in the second drying box 100 is set to be relatively low, so that the melon seeds can be slowly dried at low temperature. After being dried in the second drying box 100, the melon seeds are transported to the third drying box 100 for drying, thereby completing the graded drying of the melon seeds at different temperatures, and the melon seeds have a better drying effect. The three drying boxes 100 in this embodiment are independent of each other. Therefore, after the first batch of melon seeds are transported to the first lifting device 300, another batch of melon seeds can be transported to the first drying box 100 for drying, that is, the multi-stage melon seed dryer in this embodiment can simultaneously grade and dry different batches of melon seeds at different temperatures. Of course, the multi-stage melon seed drying machine in this embodiment is not limited to three-stage drying. In actual production applications, the number of drying boxes 100 in this embodiment can be reasonably set according to actual drying needs.
[0023] like Figure 1 and Figure 2 As shown, the conveying device 200 in this embodiment includes a transmission chain belt 220 and two parallel transmission rollers 210, and the transmission chain belt 220 is sleeved on the two transmission rollers 210; the transmission chain belt 220 includes a plurality of hinged unit chain plates 221, and baffles 223 are arranged on both sides of the unit chain plates 221. In this embodiment, the transmission roller 210 is connected to the motor, and the motor drives the transmission roller 210 to rotate, which can drive the transmission chain belt 220 to move, thereby realizing the transportation of melon seeds; in this embodiment, baffles 223 are arranged on the front and rear sides of the unit chain plates 221, and when the unit chain plates 221 are located in a horizontal plane, the baffles 223 of adjacent unit chain plates 221 can be close together, thereby preventing the melon seeds from falling off the unit chain plates 221 during the transportation process.
[0024] like Figure 2 As shown, a plurality of vents 222 are provided on the unit chain plate 221 in this embodiment. In this embodiment, when the melon seeds are dried, the moisture in the melon seeds will be released from the inside of the melon seeds into the air, thereby achieving the effect of removing the moisture from the melon seeds. Since the melon seeds are piled on the transmission chain belt 220, the moisture released by the melon seeds at the bottom needs to pass through the gaps in the melon seeds above to be released into the air. In this embodiment, the vents 222 are provided on the unit chain plate 221 of the transmission chain belt 220, so that the moisture generated by the melon seeds at the bottom during heating and drying can be directly released from the vents 222 into the air, so the melon seeds have a better drying effect; and in this way, the drying effect of the melon seeds at the bottom and the melon seeds at the upper layer can be basically the same, so the melon seeds are dried more evenly.
[0025] like Figure 1 and Figure 3As shown, the lifting device 300 in this embodiment includes a feed hopper 310, a transport channel 320 and a discharge hopper 330. The feed hopper 310 is located below the discharge end of the upper conveying device 200, and the discharge hopper 330 is located above the feed end of the lower conveying device 200. The feed hopper 310 and the discharge hopper 330 are connected through the transport channel 320. A plurality of transport hoppers 321 are evenly arranged in the longitudinal direction of the transport channel 320, and the transport hoppers 321 are connected to the driving mechanism. In this embodiment, after the melon seeds fall from the discharge end of the upper conveying device 200, they will enter the transport hopper 321 through the feed hopper 310 of the lifting device 300. In this embodiment, the transport hopper 321 can be driven by the driving mechanism to move in the transport channel 320 so as to lift and transport the melon seeds to the discharge hopper 330. Then, after the melon seeds are poured into the feed hopper 330 by the transport hopper 321, the melon seeds fall to the feed end of the lower conveying device 200. In order to allow the melon seeds to fall onto the conveying device 200 better, a discharge pipe 331 is provided below the discharge hopper 330 in this embodiment, and the melon seeds are guided by the discharge pipe 331 so that they can fall onto the conveying device 200 accurately.
[0026] The driving mechanism in this embodiment includes a driving sprocket, a passive sprocket and a chain, the chain is wound around the driving sprocket and the passive sprocket, the transport bucket is fixed on the chain, and the driving sprocket is connected to the motor. In this embodiment, the motor drives the driving sprocket to rotate so that the chain can move the transport bucket 321 along the transport channel.
[0027] like Figure 1 and Figure 4 As shown, the heating device in this embodiment is a thermal oil heating tube 400. In this embodiment, the thermal oil heating tube 400 is used to heat and dry the melon seeds. The heating temperature of the thermal oil heating tube 400 is easier to control, and the chemical properties of the thermal oil are relatively stable and have a longer service life.
[0028] like Figure 1 and Figure 4 As shown, in this embodiment, the top of the drying box 100 is connected to the blowing duct 110, and the air outlet of the blowing duct 110 is directly opposite to the thermal oil heating pipe 400. In this embodiment, the thermal oil heating pipe 400 is blown by the blowing duct 110 so that the heat of the thermal oil heating pipe 400 can be transferred to the melon seeds faster, thereby improving the drying efficiency of the melon seeds. At the same time, the blowing duct 110 can also increase the movement of hot air in the drying box 100 so that the melon seeds are dried more evenly.
[0029] In this embodiment, the melon seeds are conveyed to the lifting device 300 after being dried in the upper-level drying box 100. The melon seeds can dissipate heat and cool down on the lifting device 300, and then be conveyed to the lower-level drying box 100 for low-temperature drying. Another batch of melon seeds can be dried at high temperature in the upper-level drying box 100. The two batches of melon seeds do not affect each other. Therefore, the utility model can realize graded drying of melon seeds at different temperatures, and the melon seeds drying effect is better.
