DETAILED DESCRIPTION

[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0031] Embodiment 1

[0032] like Figures 1 to 8 As shown, a betel nut circulating drying device according to an embodiment of the present invention comprises a conveying structure 1, the conveying structure 1 is used to convey betel nut fruits, the conveying structure 1 comprises a conveyor belt 11, one end of the conveyor belt 11 is provided with a drying structure 3, the drying structure 3 comprises a box body 31, the inner wall of the box body 31 is provided with an electric heating pipe 32, and the interior of the drying structure 3 is provided with an adjusting structure 4; the adjusting structure 4 comprises: a transfer crawler 403, the transfer crawler 403 is arranged inside the drying structure 3; a collecting crawler 404, the collecting crawler 404 is arranged inside the drying structure 3 and is located below the transfer crawler 403; a plurality of collecting molds 407, the plurality of collecting molds 407 are arranged on the surface of the collecting crawler 404; a plurality of placement grooves 417, the plurality of placement grooves 417 are opened on the surface of the collecting mold 407; a magnet 411, the magnet 411 is arranged on the surface of the collecting crawler 404, and the magnet 411 is connected to the collecting mold 407; a buckle 415, the buckle 415 is slidably connected to the surface of the collecting mold 407.

[0033] Specifically, the drying process of betel nuts is also called drying process. In the prior art, a large amount of betel nuts are placed on the surface of a tray, and then the tray is placed inside a dryer. Multiple layers of trays are placed inside the dryer so that more betel nuts can be dried each time the dryer is used. After a period of time, the tray is taken out, and the betel nuts on the surface of the tray are dried. However, during the drying process, the position of the betel nuts does not change, which not only causes the contact surface between the betel nuts and the tray to not be properly dried, but also causes the piled betel nuts to affect each other, resulting in poor drying effect. Therefore, a betel nut circulating drying device is designed. When the betel nuts need to be dried, the betel nuts are first placed on the tray. The betel nuts are placed on the surface of the conveyor belt 11, and several are placed at one time. Since the betel nuts are in an oblate spherical shape at this time, they will lie flat on the surface of the conveyor belt 11. Then the conveyor belt 11 is started, and the conveyor belt 11 will drive the betel nuts to move in the direction of the drying structure 3, and the strips arranged on the surface of the conveyor belt 11 will separate the betel nuts placed each time, and finally the betel nuts will fall on the surface of the transfer crawler 403. At this time, the electric heating tube 32 is started. Since the electric heating tube 32 is a tubular electric heating element and a resistance wire is arranged inside, when the resistance wire is energized, the resistance wire will generate a large amount of heat energy, thereby increasing the temperature inside the drying structure 3, and finally achieving the purpose of drying the betel nuts. During the transportation process, the betel nuts on the surface of the transfer crawler 403 will complete the initial After the drying process, the betel nut will fall on the surface of the collecting mold 407. Since a placement groove 417 is provided on the surface of the collecting mold 407, and the end of the placement groove 417 is an arc surface, the betel nut can be more easily dropped into the placement groove 417 and placed vertically, and one placement groove 417 corresponds to one betel nut. At this time, the surface of the betel nut can be dried for a second time to achieve comprehensive drying. In the process of drying, the betel nut also enters the interior of the collecting mold 407 to achieve collection. In the process of the collecting mold 407 rotating to the lower end of the collecting crawler 404, it will pass through the arc surface at one end of the collecting crawler 404. Since the magnet 411 on the surface of the collecting crawler 404 will adsorb the collecting mold 407, and the end of the collecting crawler 404 will be attracted by the magnet 411. The curvature of the arc surface is extremely large, so that the collecting mold 407 can easily pass through the arc surface at the end of the collecting crawler 404 when transferring. When the collecting mold 407 moves to the lower end of the collecting crawler 404, the buckle 415 is started, and the buckle 415 will move toward the corresponding placement groove 417, and finally block the placement groove 417, so that the betel nut will not fall. Then, you only need to take out the collecting mold 407 and place a new collecting mold 407 on the upper surface of the collecting crawler 404. With the continuous transportation of the conveyor belt 11, the cyclic drying of the betel nut is completed. In the drying process, it can also ensure that each betel nut can be fully dried. After the drying is completed, each betel nut can also be collected separately, which is very convenient.

[0034] like Figures 1 to 7 As shown, the adjustment structure 4 also includes: an outlet port 401, which is opened on the side wall of the box body 31; an upper plate port 402, which is opened on one end of the side wall of the box body 31 close to the outlet port 401; a plurality of clamping plates 409, which are arranged on the surface of the collecting crawler 404, and the plurality of clamping plates 409 are grouped in pairs, and the collecting mold 407 is slidably connected to the inner wall of each group of clamping plates 409; a limiting plate 406, which is arranged at the upper end of one of each group of clamping plates 409; A rotating shaft 412, which is disposed at the upper end of two of each set of clamping plates 409; a movable plate 405, which is rotatably connected to the arc surface of the rotating shaft 412; an abutment bar 408, which is disposed inside the box body 31, and the movable plate 405 contacts the abutment bar 408 when moving; an abutment rod 416, which is slidably connected to the inside of the collecting mold 407, and the abutment rod 416 is connected to the buckle 415, and the movable plate 405 contacts the abutment rod 416 when rotating.

[0035] Specifically, when it is necessary to fix the collecting mold 407 on the surface of the collecting track 404, it is only necessary to push the collecting mold 407 along the inner wall of each set of snap-on plates 409, and when the betel nut falls from the transfer track 403 onto the surface of the collecting mold 407, the limiting plate 406 and the movable plate 405 will also prevent the betel nut from splashing out of the outside of the collecting mold 407, and then when the collecting mold 407 is about to rotate to the bottom of the collecting track 404, the movable plate 405 will contact the abutment bar 408, and finally the movable plate 405 will rotate around the rotating shaft 412 as the axis, and rotate to be parallel to the limiting plate 406, at this time the movable plate 405 will contact the abutment rod 416, and the snap 415 will be pushed to the surface of the placement groove 417 through the abutment rod 416, so that the betel nut will not fall, and by setting the outlet plate port 401 and the upper plate port 402, the collection mold 407 can be installed and removed more easily.

[0036] like Figures 1 to 3 As shown, the transfer crawler 403 is placed obliquely inside the box 31 , and the higher inclined end of the transfer crawler 403 is away from the conveying structure 1 .

[0037] Specifically, by setting the transfer crawler 403 to an inclined state, when the transfer crawler 403 is transporting the betel nuts, the betel nuts will be subjected to a gravity component force in the opposite direction of the movement of the transfer crawler 403, thereby making it easier to separate the accumulated betel nuts.

[0038] like Figures 1 to 3 As shown, a plurality of limiting strips 420 are provided on the surface of the transfer crawler 403, and the transfer crawler 403 is in contact with the betel nut.

[0039] Specifically, by setting the limiting strip 420, when the transfer track 403 moves with the betel nut, the limiting strip 420 will limit the moving direction of the betel nut, which can not only isolate it from the subsequent betel nut, but also prevent the betel nut from slipping.

[0040] like Figures 4 to 5 As shown, a coil spring 413 is sleeved on the surface of the rotating shaft 412 , and one end of the coil spring 413 is connected to the movable plate 405 .

[0041] Specifically, by setting the coil spring 413, when the collecting mold 407 is taken out, since the movable plate 405 is no longer in contact with the abutment strip 408, the coil spring 413 will release the elastic force at this time, and finally drive the movable plate 405 to reset, so as to facilitate the subsequent drying and collection of betel nuts.

[0042] like Figures 1 to 4 As shown, a plurality of auxiliary steel balls 410 are disposed on the surface of the collecting track 404 , and the auxiliary steel balls 410 are in contact with the bottom surface of the collecting mold 407 .

[0043] Specifically, by providing the auxiliary steel ball 410, the friction between the collecting mold 407 and the collecting track 404 can be reduced when the collecting mold 407 is installed and removed, so that the movement of the collecting mold 407 is smoother.

[0044] like Figures 4 to 5 As shown, the side wall of the clamping plate 409 close to one end of the collecting mold 407 is rotatably connected to an intermittent gear 414, and the intermittent gear 414 contacts the collecting mold 407 when rotating.

[0045] Specifically, by setting an intermittent gear 414, when the collecting mold 407 moves to the side wall of the clamping plate 409, the rack on the surface of the intermittent gear 414 will not contact the collecting mold 407. Then, the intermittent gear 414 is started, and the intermittent gear 414 will push the collecting mold 407 in the direction parallel to the side wall of the clamping plate 409. When the rack on the surface of the intermittent gear 414 does not contact the collecting mold 407, the collecting mold 407 will move to contact the intermittent gear 414 at the other end of the side wall of the clamping plate 409. As the intermittent gear 414 at the other end rotates, the collecting mold 407 will be pushed back to its original position. With repeated operations, the collecting mold 407 will shake on the side wall of the clamping plate 409, thereby facilitating the betel nut to enter the interior of the placement groove 417.

[0046] Embodiment 2

[0047] like Figure 8 As shown, in comparison with Example 1, another embodiment of the present invention is that a feeding structure 2 is provided at the upper end of the conveyor belt 11, and the feeding structure 2 includes a feeding barrel 21.

[0048] Specifically, by arranging a loading barrel 21 at the upper end of the conveyor belt 11, betel nuts can be automatically loaded, and the number of betel nuts loaded each time can be controlled, thereby realizing an automated process.

[0049] like Figure 8 As shown, the opening of the upper barrel 21 is rotatably connected to a discharge gear 419, and the discharge gear 419 is in contact with the betel nut.

[0050] Specifically, by setting a feeding gear 419, when it is necessary to feed betel nuts, the feeding gear 419 is started to rotate, and the rack on the surface of the feeding gear 419 will drive the betel nuts to move, so that the betel nuts to be fed are located between the two racks. Moreover, through the rotation of the feeding gear 419, the betel nuts located inside the feeding barrel 21 will not be blocked.

[0051] like Figure 8 As shown, a smoothing rod 418 is slidably connected to one end of the surface of the conveyor belt 11 close to the upper barrel 21, and the smoothing rod 418 is in contact with the betel nut.

[0052] Specifically, since the opening of the loading barrel 21 is at a certain distance from the conveyor belt 11, betel nuts are prone to accumulation when they move to the surface of the conveyor belt 11. By providing a smoothing rod 418, when the betel nuts fall on the surface of the conveyor belt 11, the smoothing rod 418 is started and moved toward the direction of the betel nuts, eventually smoothing the accumulated betel nuts, thereby avoiding the problem of the accumulated betel nuts falling off during subsequent upward transportation.

[0053] Working principle: When it is necessary to dry the betel nut, start the unloading gear 419 to rotate. Since the betel nut is located inside the upper barrel 21, the rack on the surface of the unloading gear 419 will drive the betel nut to move, so that the betel nut to be unloaded is located between the two racks. Finally, the betel nut will pass through the opening of the upper barrel 21 and finally fall on the surface of the conveyor belt 11. Since the betel nut is in an oblate spherical shape at this time, the betel nut will lie flat on the surface of the conveyor belt 11. Then start the conveyor belt 11, which will drive the betel nut to move in the direction of the drying structure 3, and the strips arranged on the surface of the conveyor belt 11 will separate the betel nut placed each time, and finally the betel nut will fall on the transfer shoe. The surface of the belt 403 is turned on, and the electric heating tube 32 is started and the collecting mold 407 is installed. Since the electric heating tube 32 is a tubular electric heating element and a resistance wire is arranged inside, when the resistance wire is energized, the resistance wire will generate a large amount of heat energy, thereby increasing the temperature inside the drying structure 3, and finally achieving the purpose of drying the betel nut. During the transportation process, the betel nut on the surface of the transfer crawler 403 will complete the initial drying process, and then the betel nut will fall on the surface of the collecting mold 407. At this time, the limiting plate 406 and the movable plate 405 will prevent the betel nut from splashing out of the collecting mold 407. Since a placement groove 417 is opened on the surface of the collecting mold 407, and the placement groove 417 The end of the collecting track 404 is an arc surface, so that the betel nut can be more easily dropped into the placing groove 417 and placed vertically, and one placing groove 417 corresponds to one betel nut. At this time, the surface of the betel nut can be dried for a second time to achieve comprehensive drying. In the drying process, the betel nut also enters the interior of the collecting mold 407 to achieve collection. When the collecting mold 407 rotates to the lower end of the collecting crawler 404, it will pass through the arc surface at one end of the collecting crawler 404. Since the magnet 411 on the surface of the collecting crawler 404 will adsorb the collecting mold 407, and the arc surface at the end of the collecting crawler 404 has a large curvature, the collecting mold 407 can easily pass through the collecting crawler 404 when it is transferred. The arc surface at the end of the track 404, when the collecting mold 407 moves to the lower end of the collecting track 404, the movable plate 405 will contact with the abutment bar 408, and finally the movable plate 405 will rotate with the rotating shaft 412 as the axis, and rotate to be parallel to the limit plate 406. At this time, the movable plate 405 will contact with the abutment rod 416, and the buckle 415 will be pushed to the surface of the placement groove 417 through the abutment rod 416, so that the betel nut will not fall, and by setting the outlet plate port 401 and the upper plate port 402, the collection mold 407 can be installed and removed more easily, and the continuous transportation of the conveyor belt 11 can complete the cyclic drying of the betel nut.
