[0022] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.
[0023] like Figure 1 , Figure 2 , Figure 3As shown, it is a structural diagram of a melon seed processing and drying device provided by an embodiment of the present invention, comprising a drying cylinder 1, the drying cylinder 1 is a hollow cylindrical structure, a feeding port 11 is arranged at the top of the drying cylinder 1, a side door 12 is arranged at the bottom wall of the drying cylinder 1, a feeding funnel 13 located outside the feeding port 11 is fixedly installed on the surface of the drying cylinder 1, a plurality of groups of drying tubes 2 are fixedly installed in the inner cavity of the drying cylinder 1, the plurality of groups of drying tubes 2 are horizontally placed and evenly spaced along a vertical plane, the drying tubes 2 are connected to an external hot air blower, a material guiding assembly 3 located outside the drying tube 2 is arranged in the inner cavity of the drying cylinder 1, the material guiding assembly 3 is used to control the movement of the seeds from top to bottom on both sides of the drying tube 2 in the inner cavity of the drying cylinder 1, and the material guiding assembly 3 is used to reduce the seeds in the inner cavity of the drying cylinder 1. The speed at which both sides of the drying tube 2 move downward, the inner cavity of the drying cylinder 1 is provided with a circulating feeding mechanism 4, the circulating feeding mechanism 4 includes a push plate 41, a positioning component 42 and a transmission component 43, the push plate 41 is provided with multiple groups, the positioning component 42 is located on the inner wall of the drying cylinder 1 and is connected to the push plate 41, the positioning component 42 is used to control the multiple groups of push plates 41 to be closely attached to the inner wall of the drying cylinder 1 and to be distributed in a circular manner with equal spacing, the transmission component 43 is located on the surface of the drying cylinder 1 and is connected to the positioning component 42, the transmission component 43 controls the multiple groups of push plates 41 to rotate in the inner cavity of the drying cylinder 1 by cooperating with the positioning component 42, the inner cavity of the drying cylinder 1 is fixedly installed with a baffle 411 that cooperates with the push plate 41, and the baffle 411 is an arc-shaped structure.
[0024] When drying the grains, the hot air blower blows dry hot air toward the inner cavity of the drying cylinder 1 through the drying pipe 2, and puts the grains into the drying cylinder 1 through the feed port 11. The material guiding component 3 controls the falling path and speed of the grains, effectively slowing down the falling speed of the grains. During the falling process of the grains, the drying pipe 2 can blow and dry the grains. During the blowing and drying process, the material guiding component 3 can control the dispersion and falling of the grains, and the grains are fully in contact with the hot air, effectively improving the drying effect of the grains. After the grains fall to the bottom of the drying cylinder 1, when it is necessary to repeatedly blow-dry the grains, the transmission component 43 cooperates with the positioning component 42 to drive multiple groups of push plates 41 to rotate along the annular inner wall of the drying cylinder 1. The push plates 41 push the grains at the bottom of the drying cylinder 1 to move synchronously when rotating. The push plates 41 cooperate with the baffle 411 to transport the grains at the bottom of the drying cylinder 1 to the top of the drying cylinder 1, and then control the grains at the top of the drying cylinder 1 to fall into the material guide component 3 again, so that the grains can be repeatedly blown and dried, effectively improving the drying effect of the grains.
[0025] like Figure 2 , Figure 3 , Figure 4As shown, as a preferred embodiment of the present invention, the material guide assembly 3 includes an outer material guide plate 31 fixedly installed in the inner cavity of the drying cylinder 1 and sleeved on the outer side of the drying tube 2, the outer material guide plate 31 is a relatively distributed wavy structure along the vertical direction, and an inner material guide ring 32 fixedly installed in the inner cavity of the drying cylinder 1 and sleeved on the outer side of the drying tube 2, a material discharge channel 33 is formed between the outer material guide plate 31 and the inner material guide ring 32, a material discharge port 34 is provided at the top end of the outer material guide plate 31, and a material discharge port 35 is provided at the bottom end of the outer material guide plate 31, and the surfaces of the outer material guide plate 31 and the inner material guide ring 32 are respectively provided with evenly distributed ventilation meshes.
[0026] The grains fall from the feed port 11 and further pass through the discharge port 34 to fall into the discharge channel 33. The discharge channel 33 is an arc-shaped structure, which can effectively slow down the falling speed of the grains. During the falling process of the grains, the drying tube 2 blows out hot air, which can efficiently dry the grains in the discharge channel 33. When the grains fall, the discharge channel 33 can control the grains to fall randomly in the discharge channel 33, and the batches of grains can be fully exposed to the hot air, effectively improving the drying effect. After the grains fall to the bottom of the discharge channel 33, they pass through the discharge port 35 and fall to the bottom of the drying cylinder 1.
[0027] like Figure 2 , Figure 3 , Figure 5 , Figure 6 As shown, as a preferred embodiment of the present invention, the positioning assembly 42 includes two sets of relatively distributed annular guide grooves 421 opened on the annular inner wall of the drying cylinder 1, and a fixing ring 422 is rotatably installed in the guide groove 421. The fixing ring 422 extends to the outside of the guide groove 421 and is fixedly connected to the push plate 41.
[0028] The fixed ring 422 supports and positions the multiple groups of push plates 41 in the inner cavity of the drying cylinder 1. When the grains fall to the bottom of the drying cylinder 1, the grains are between the two groups of push plates 41. When the grains need to be repeatedly dried, the transmission assembly 43 controls the fixed ring 422 to rotate in the guide groove 421. The fixed ring 422 drives the multiple groups of push plates 41 to rotate synchronously in the inner cavity of the drying cylinder 1. When rotating, the push plates 41 will push the grains at the bottom of the drying cylinder 1 to move synchronously. The push plates 41 cooperate with the baffle 411 to conveniently transport the grains to the top of the drying cylinder 1 and put the grains into the unloading channel 33.
[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6As shown, as a preferred embodiment of the present invention, the transmission assembly 43 includes an annular tooth groove 431 provided on the surface of the fixing ring 422, a connecting groove 432 connected to the guide groove 421 is provided on the surface of the drying cylinder 1, two groups of side plates 433 are fixedly installed on the surface of the drying cylinder 1, a dual-axis motor 434 is fixedly installed between the two groups of side plates 433, a transmission gear disc 435 is fixedly installed on the output shaft of the dual-axis motor 434, and the transmission gear disc 435 passes through the connecting groove 432 and extends into the guide groove 421 and is meshed with the tooth groove 431.
[0030] When in use, the dual-axis motor 434 drives the transmission gear plate 435 to rotate, and the transmission gear plate 435 engages with the tooth groove 431 for transmission, which can drive the fixing ring 422 to rotate in the guide groove 421 .
[0031] like Figure 1 , Figure 3 As shown in FIG. 1 , as a preferred embodiment of the present invention, a plurality of evenly distributed air holes 5 are provided on the surface of the drying cylinder 1 . When the seeds are dried, the evaporated water vapor can be discharged to the outside of the drying cylinder 1 through the air holes 5 .
[0032] like Figure 1 , Figure 3 As shown in FIG. 1 , as a preferred embodiment of the present invention, a water-permeable hole 6 is provided at the bottom wall of the drying cylinder 1. The water-permeable hole 6 can automatically drain the excess water on the surface of the grains.
[0033] like Figure 2 , Figure 3 , Figure 4 As shown, as a preferred embodiment of the present invention, a material guide plate 7 located outside the material discharge port 34 is fixedly mounted on the surface of the outer material guide plate 31 .
[0034] The working principle of the present invention is as follows: when drying the grains, the hot air blower blows the dry hot air to the inner cavity of the drying cylinder 1 through the drying pipe 2, and the grains are put into the drying cylinder 1 through the feed port 11. The grains fall from the feed port 11 and further pass through the discharge port 34 to fall into the discharge channel 33. The discharge channel 33 is an arc-shaped structure, which can effectively slow down the falling speed of the grains. During the falling process of the grains, the drying pipe 2 blows out hot air, which can efficiently dry the grains in the discharge channel 33. When the grains fall, the discharge channel 33 can control the grains to fall randomly in the discharge channel 33, and batches of grains can be fully in contact with the hot air, effectively improving the drying effect. After the grains fall to the bottom of the discharge channel 33, they pass through the discharge port 35 and fall to the bottom of the drying cylinder 1.
[0035] When the grains fall to the bottom of the drying cylinder 1, the grains are between the two groups of push plates 41. When the grains need to be dried repeatedly, the dual-axis motor 434 drives the transmission gear plate 435 to rotate, and the transmission gear plate 435 is meshed with the tooth groove 431 for transmission, which can drive the fixed ring 422 to rotate in the guide groove 421. The fixed ring 422 drives multiple groups of push plates 41 to rotate synchronously in the inner cavity of the drying cylinder 1. When the push plates 41 rotate, they push the grains at the bottom of the drying cylinder 1 to move synchronously. The push plates 41 cooperate with the baffle 411 to conveniently transport the grains to the top of the drying cylinder 1 and put the grains into the unloading channel 33. The grains can be repeatedly blown and dried, effectively improving the drying effect of the grains.
[0036] The preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of the present invention.
