Description

Technical Field

[0001] The utility model relates to the technical field of tobacco leaf processing equipment, in particular to a tobacco leaf insecticidal effect sampling device. Background Art

[0002] After tobacco leaves are baked and dried, they should not be made into cigarettes immediately, otherwise there will be a pungent and irritating smell, and the smoking quality will be poor. Only after a considerable period of storage, the tobacco leaves have undergone significant improvements in color, aroma, taste, etc., and are suitable for being made into tobacco and cigarettes. We call this process "natural aging". Natural aging takes 1-3 years. During the process of harvesting, baking, drying, and packaging, a large number of microorganisms are attached to the surface and inside of the tobacco leaves. The tobacco leaves themselves are rich in nutrients. When the relative humidity of the storage environment exceeds 65%, the tobacco leaves are very easy to be infested with insects and mold.

[0003] Therefore, it is necessary to kill insects before purifying tobacco leaves. The existing method of killing insects is to seal a batch of tobacco leaves, place them on a tray, and pass nitrogen gas through them. It is estimated based on experience that the parasites on the tobacco leaves have been killed, and then the sealed packages are opened for subsequent processing. This method has high requirements for staff and low reliability. Utility Model Content

[0024] like Figure 1-6 As shown, the embodiment of the utility model proposes a tobacco leaf insecticidal effect sampling device, including a circular tray 1, a slide rail is arranged at the edge of the tray 1 along the circumference of the tray 1, and a slide seat 4 is slidably connected to the slide rail. In fact, the sampling position of the sampling device can be adjusted by the cooperation of the electric guide rail and the slide seat 4. In this embodiment, the slide rail includes a circular slide plate 2 arranged along the circumference of the tray 1, and two round steel guide rails 3 are arranged on the top of the slide plate 2 along the circumference of the tray 1. The diameters of the two round steel guide rails 3 are different, and the centers of the circles overlap with the center of the circle of the tray 1. The bottom of the slide seat 4 is provided with an opening 5 adapted to the round steel guide rail 3, and the round steel guide rail 3 is slidably embedded in the opening 5. The bottom wall of the slide seat 4 is in sliding contact with the top surface of the slide plate 2, and the round steel guide rail 3 is welded to the top surface of the slide plate 2.

The overall structure of the slide rail is simple, and the materials are all existing profiles, which are easy to obtain, easy to manufacture, low cost, stable support, and small sliding resistance.

[0025] A support plate 17 is fixed on the outside of the sliding seat 4. A bracket 6 is fixed on the top of one end of the support plate 17 away from the sliding seat 4. The bracket 6 includes a first support rod 61 and a second support rod 62 slidably arranged in the first support rod 61. The bottom of the first support rod 61 is fixedly installed on the upper surface of the sliding seat 4. A locking assembly is arranged between the first support rod 61 and the second support rod 62. In fact, a connecting hole can be opened through the top of the first support rod 61, and a plurality of through holes penetrating the second support rod 62 can be opened on the second support rod 62 along the axial direction of the second support rod 62. The second support rod 62 slides axially along the first support rod 61 so that the through hole can be connected with the connecting hole. At this time, the locking assembly is a bolt and a nut. One end of the bolt passes through the connecting hole and the through hole in turn, and then cooperates with the nut to lock and fix the first support rod 61 and the second support rod 62. In this embodiment, the locking assembly includes a limit frame 9 and a locking piece 10. The locking piece 10 is a bolt. The limit frame 9 is fixedly sleeved on the top of the first support rod 61 by the bolt. A through hole is provided on one side of the first support rod 61 for the locking piece 10 to pass through. The limit frame 9 is provided with a through hole for the locking piece 10 to pass through. The through holes are connected to the through holes. One end of the locking piece 10 passes through the through hole and the through hole in turn, and abuts against the second support rod 62 to form a locking fixation for the first support rod 61 and the second support rod 62. The through hole and the through hole are both threaded holes. By twisting the locking piece 10, the second support rod 62 can be locked or loosened, so that the height of the bracket 6 can be directly adjusted. The structure is simple and the adjustment is convenient, and the adjustment height of the second support rod 62 can be at any position.

[0026] A mounting seat 7 is fixedly provided on the top of the second support rod 62, and an electric telescopic rod 8 is fixedly installed on the mounting seat 7 by bolts. The electric telescopic rod 8 is horizontally arranged, and the telescopic end of the electric telescopic rod 8 faces the inner side of the tray 1. A clamping mechanism is fixedly provided on the telescopic end of the electric telescopic rod 8. In this embodiment, the mounting seat 7 forms a stable support for the electric telescopic rod 8.

[0027] The clamping mechanism includes a mounting plate 11, which is vertically mounted on the end face of the telescopic end of the telescopic rod 8 and extends along the length direction of the telescopic rod 8. Two rotating shafts 12 are rotatably connected to the mounting plate 11, and the two rotating shafts 12 are symmetrically distributed on both sides of the electric telescopic rod 8. A gear 13 is fixedly sleeved on each rotating shaft 12, and a clamping arm 16 is provided on each gear 13. One end of the clamping arm 16 is integrally formed with a tooth of the gear 13, and the other end of the clamping arm 16 extends in a direction away from the electric telescopic rod 8 to form a suspended end. In this embodiment, the two clamping arms are staggered and hinged to each other. The structure formed by the two clamping arms is similar to that of fire clamps, and the front end thereof is pointed, which is convenient for inserting into tobacco leaves.

[0028] A support frame 18 is arranged between the electric telescopic rod 8 and the mounting plate 11. The support frame 18 is a box body formed by a bottom wall, a top wall and four side walls. One side wall of the support frame 18 is fixedly connected to the telescopic end of the electric telescopic rod 8. The mounting plate 11 is vertically fixed to the outer surface of the side wall of the support frame 18 away from the electric telescopic rod 8 by bolts. The clamping mechanism also includes a driving assembly for driving the two gears 13 to rotate simultaneously in opposite directions. The driving member includes an electric cylinder 15 and a strip block 14. The strip block 14 is located between the two gears 13. Tooth grooves meshing with the two gears 13 are respectively arranged on both sides of the strip block 14 along the length direction of the strip block 14. The electric cylinder 15 is fixedly installed on the inner wall of the mounting frame by bolts, and the telescopic end of the electric cylinder 15 is fixedly connected to one end of the strip block 14.

[0029] In the above embodiment, a through hole for the strip block 14 to pass through is provided on the side wall of the support frame 18 away from the electric telescopic rod 8; a control box (not shown in the figure) is arranged in the support frame 18 to power and control the electric cylinder 15. The strip block 14 is in sliding contact with the mounting plate 11. Through the extension and retraction of the electric cylinder 15, the strip block 14 can be driven to move axially along the electric telescopic rod 8, thereby driving the two gears 13 to rotate in opposite directions at the same time, thereby driving the two clamping arms 16 to close or open, so as to clamp the tobacco leaf sample.

[0030] In actual use, the tobacco leaves are placed on the tray 1 by an electronic forklift, and the bracket 6 is adjusted to a suitable height by tightening or loosening the locking piece 10. The staff manually moves the sliding seat 4 to rotate the bracket 6 to the position where sampling is required, and extends the electric telescopic rod 8 to drive the clamping mechanism to insert the tobacco leaves into the tobacco leaf pile sealed by multi-layer film wrapping. Before this, the film can be cut with a knife in advance at the position where sampling is required to facilitate the insertion of the clamping mechanism into the tobacco leaf pile, which can reduce damage to the tobacco leaves. When the clamping mechanism arrives at the sampling position, the electric cylinder 15 drives the front end of the lower clamping arm 16 to open and clamp the tobacco leaf sample and then close it again. The sampling is accurate. After the clamping mechanism collects the tobacco leaf sample, the electric telescopic rod 8 withdraws from the tobacco leaf pile, obtains the tobacco leaf sample from the clamping mechanism to complete the sampling, and then starts sampling at the next position. The sampling is convenient, and the insecticidal effect is obtained by testing the tobacco leaf sample, and the result is more reliable.
