DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example 1

[0032] See also Figure 2 , Figure 4 , Figure 5 and Figure 6 , which is the first embodiment of the present invention, provides a tobacco harvesting component. Through the use of the harvesting component 400, it is convenient to adjust the multi-tooth rake group 405 to multiple positions, realize the cycle of the tobacco leaf harvesting process, and thus improve the harvesting efficiency.

[0033] Specifically, the harvesting assembly 400 includes two symmetrically arranged positioning bars 401, two sliding plates 403 arranged at opposite end positions of the positioning, two obliquely symmetrical rotating swing arms 404 located between the two sliding plates 403, and a multi-toothed rake group 405 located at the end of the rotating swing arm 404. The multi-toothed rake group 405 is controlled to start the action, and the teeth on the multi-toothed rake group 405 are used to press down the tobacco leaves, so that the tobacco leaves can be separated from the tobacco rods, so as to achieve the purpose of harvesting tobacco leaves. There are two obliquely symmetrical rotating swing arms 404 located between the two sliding plates 403. The swing arm shaft 403a is called, and the two rotating swing arms 404 are respectively sleeved on the adjacent swing arm shaft 403a through the rotating sleeves fixed at the ends; the opposite end surfaces of the two positioning bars 401 are provided with sprocket sets 401a, and the sprocket sets 401a are connected by the sleeved chain 401b, and the opposite end surfaces of the two sliding plates 403 are fixed with sliders 403d, and the sliders 403d are fixedly connected to the adjacent chains 401b; wherein, the end surface of any one of the positioning bars 401 is fixed with a lifting motor 402 connected by the sprocket set 401a;

[0034] Through the use of the above structure, the lifting motor 402 is controlled to work, thereby the lifting motor 402 drives the sprocket group 401a to rotate, and thereby controls the chain 401b to move, so that the chain 401b drives the slider 403d to move in the up and down directions, and then the slider 403d drives the sliding plate 403 to move, and thereby drives the multi-tooth rake group 405 to move up and down. The multi-tooth rake group 405 mainly has four node positions during the tobacco collection process. When it is in position one, the multi-tooth rake group 405 is close to the tobacco rod, and then the lifting motor 402 works, which will drive the chain 401b to control the sliding plate 403 to move, thereby driving the multi-tooth rake group 405 to move downward. The multi-tooth rake group 405 moves to position 2, and the active motor 403c is controlled to work. The active motor 403c controls the gear 403b to move through the gear, and thereby drives the swing arm shaft 403a and the rotating swing arm 404 to transmit, so that the multi-tooth rake group 405 is away from the tobacco rod, and thus reaches position 3, and then controls the lifting and lowering to rotate in the opposite direction, thereby driving the multi-tooth rake group 405 to move upward, so as to reach position 4, and controls the active motor 403c to work in the reverse direction, so that the multi-tooth rake group 405 is close to the tobacco rod, thereby controlling the multi-tooth rake group 405 to reset to the initial position 1, so as to enter the next round of tobacco collection action cycle.

[0035] It should be noted that all the motors used are controlled by the control center on the equipment. Example 2

[0036] See also Figure 2 and Figure 4 Based on the embodiment 1, this embodiment works through the active motor 403c to facilitate the control of the multi-tooth rake group 405 for position adjustment.

[0037] Specifically, a rotating shaft 401c with the same height as the lifting motor 402 is rotatably arranged between the two positioning bars 401, and both ends of the rotating shaft 401c are fixedly connected to the shaft ends of the sprocket group 401a, and the ends of the swing arm shaft 403a passing through the sliding plate 403 are fixed with moving gears 403b, and the end face of the sliding plate 403 located in the front is fixed with an active motor 403c meshingly connected with the moving gear 403b, and a fixed seat 404a is arranged at the lower position between the two sliding plates 403, and the lower ends of the two rotating swing arms 404 are rotatably connected to the fixed seat 404a, and a fixed rod 404b is fixed to the end face of the fixed seat 404a, and the fixed rod 404b is rotatably connected to the multi-tooth rake group 405 through the set tooth rake shaft 405a.

[0038] By setting and using the above structure, the active motor 403c is controlled to work, thereby the active motor 403c will drive the driven gear 403b to rotate, and thereby control the swing arm shaft 403a to rotate, thereby making the rotating swing arm 404 drive the fixed seat 404a to rotate, and thereby control the multi-tooth rake group 405 to adjust the position.

[0039] It should be noted that the harvesting components 400 are arranged in two groups, left and right, to cooperate in a circulating action, wherein the left and right harvesting components 400 are respectively arranged on both sides of the smoke column, and the rotating swing arm 404 can be fixed at different positions of the swing arm shaft 403a according to the situation, so that the two groups of multi-tooth rake groups 405 are in the same plane or staggered. Example 3

[0040] See also Figure 1 , Figure 2 The present invention provides a tobacco leaf harvesting device, which drives the tobacco leaf plucking piece 503 to rotate on the roller frame 202 through the tobacco plucking motor 501, so as to facilitate the tobacco leaf leaves to be moved to the position between the friction conveyor belt 203 and the high-position conveyor belt 201, thereby improving the conveying efficiency. At the same time, the roller frame 202, the high-position conveyor belt 201, the friction conveyor belt 203 and the tobacco collecting frame 301 are used in coordination, so as to facilitate the accurate and comprehensive collection of the harvested tobacco leaves.

[0041] Specifically, two harvesting components 400 are symmetrically located in the frame 100 inside thereof; the transmission component 200 includes two high-position conveyor belts 201 which are symmetrically arranged and arranged in the frame 100, a friction conveyor belt 203 arranged at the opposite end positions of the two high-position conveyor belts, and a roller frame 202 fixed to the lower end surface of the friction conveyor belt and arranged obliquely; the storage component 300 includes two cigarette collecting frames 301 respectively located at the left and right end positions of the frame 100 and a rotating plate 302 arranged at the opening position of the cigarette collecting frames 301; the moving component 500 includes two cigarette removing motors 501 respectively fixed on the friction conveyor belt frame 100 and a cigarette removing piece 503 located directly behind the cigarette removing motor 501; the moving component 600 includes four rollers 601 located at four diagonal positions at the lower end of the frame 100 and a tripod 602 rotatably connected to the rollers 601.

[0042] Through the arrangement and use of the above-mentioned structure, when the multi-tooth rake group 405 on the harvesting component 400 removes the tobacco leaves from the tobacco rod, the tobacco leaves fall onto the roller frame 202. Since the roller frame 202 will transport the tobacco leaves to the position between the high-position conveyor belt 201 and the friction conveyor belt 203, the high-position conveyor belt 201 and the friction conveyor belt 203 will transport the tobacco leaves upward and transport them to the folding frame 100. At the same time, the tobacco plucking motor 501 drives the tobacco plucking piece 503 to rotate, so that the tobacco plucking piece 503 can move the tobacco leaves on the roller frame 202.

[0043] according to Figure 3 , Figure 7 and Fig. 9 It can be seen that the front and rear end surfaces of the friction conveyor belt 203 are both provided with connecting frame plates 204 rotatably connected to the shaft rod ends thereof, and the connecting frame plates 204 are respectively fixed to the left and right parts inside the frame 100, and the positioning strips 401 are fixed to the corresponding connecting frame plates 204 by bolts. The two harvesting components 400 are arranged between the two transmission components 200, and the upper end surface of the friction conveyor belt 203 is located in the middle position above the gathering frame 301. Therefore, after the tobacco leaves are transported by the friction conveyor belt 203, the tobacco leaves will accurately fall into the gathering frame 301. The end surface of the tripod 602 is fixed with a moving motor 602a transmission-connected to the roller 601, and the shaft end of the tobacco-moving motor 501 is fixed with a mounting frame 502. The tobacco-moving piece 503 is connected to the mounting frame 502 by bolts and works through the moving motor 602a, so that the moving motor 602a will drive the roller 601 to rotate, and then the roller 601 drives the entire device to move in the tobacco field ridge. Example 4

[0044] See also Figure 3This embodiment realizes automatic control of transportation and improves the transportation efficiency of tobacco leaves by using the roller motor 202a, the linkage motor 203a and the high-position motor 201a in coordination.

[0045] Specifically, two connecting plates 201b that are symmetrically arranged front to back are fixed to the upper end portion of the end face of the high-position conveyor belt 201, and the connecting plates 201b are bolted to the upper end face of the connecting frame plate 204, a roller motor 202a is fixed to the frame 100 of the roller frame 202, and the roller motor 202a is transmission-connected to the rollers on the roller frame 202, a high-position motor 201a is fixed to the frame 100 of the high-position conveyor belt 201, and the high-position motor 201a is transmission-connected to the rotating shaft end of the high-position conveyor belt 201, and a linkage motor 203a is fixed to the frame 100 of the friction conveyor belt 203, and the linkage motor 203a is transmission-connected to the rotating shaft end of the friction conveyor belt 203.

[0046] Through the setting and use of the above-mentioned structure, the roller motor 202a works, thereby the roller motor 202a will drive the roller frame 202 to rotate. At the same time, when the high-position motor 201a and the linkage motor 203a are controlled to work, the high-position motor 201a will drive the high-position conveyor belt 201 to transport, and the linkage motor 203a will drive the friction conveyor belt 203 to transport, so as to transport tobacco leaves. Example 5

[0047] See also Figure 8 and Fig. 9 This embodiment controls the rotating plate 302 to rotate at the opening position of the folded tobacco frame 301, so as to facilitate pouring out the tobacco leaves inside the frame 100.

[0048] Specifically, a baffle 602b is fixed to the upper end surface of the tripod 602, and a flange block 602c bolted to the lower end surface of the frame 100 is fixed to the upper end surface of the baffle 602b. The upper end surface of the rotating plate 302 is hinged to the open end surface of the retractable cigarette frame 301 through a hinge chain 304, and the lower part of the rotating plate 302 is used in conjunction with the retractable cigarette frame 301 through a connecting buckle 303.

[0049] By setting up and using the above-mentioned structure, when it is necessary to take out the tobacco leaves inside the folded cigarette frame 301, the connecting buckle 303 is removed, thereby the rotating plate 302 can be separated from the bottom position of the opening position of the frame 100. At this time, the rotating plate 302 is rotated upward through the hinge chain 304, so that the opening position of the frame 100 can be opened, thereby allowing the tobacco leaves inside the frame 100 to be poured out.
