A multi-point sampling device for finished tobacco flakes

Abstract

A multi-point sampling device for finished tobacco leaves includes a base plate and columns supported at both ends of the base plate. A horizontal beam is fixed to the top of the columns, and a hollowed-out slide rail is provided in the center of the beam. A vertical guide sleeve slides within the slide rail, and a spiral conveyor cylinder runs vertically through the guide sleeve. A spiral auger is installed inside the spiral conveyor cylinder, and the auger is driven to rotate by a reduction motor at the upper end of the spiral conveyor cylinder. A downwardly angled discharge cylinder connected to the upper end of the spiral conveyor cylinder is fixed to one side of the cylinder. This invention eliminates the need to remove the upper layer of tobacco leaves before sampling, avoiding the impact of moisture evaporation on test results. Furthermore, the entire sampling process does not require manual handling, effectively preventing contact between the tobacco leaves and the sampling personnel's hands, thus avoiding contamination of the tobacco leaves at the sampling site. In addition, sampling via a spiral conveyor device results in higher sampling and transport efficiency, effectively saving sampling time.

Description

Technical Field

[0001] This utility model relates to a sampling device, specifically a multi-point sampling device for finished tobacco sheets. Background Technology

[0002] During the storage of finished tobacco leaves, it is necessary to sample and test the moisture content of raw tobacco leaves entering and leaving the warehouse, as well as those at different aging stages. First, samplers manually collect samples of the raw tobacco leaves, then testers crush the samples and place them in sample bottles. After moisture testing, the samples are poured into a collection bucket. In daily storage, there are many samples for moisture content testing of raw tobacco leaves at different aging stages, approximately 300 samples per day. Each sample has its own sample bottle. Currently, before testing, boxes of samples need to be opened manually, and samples need to be taken from multiple points. To obtain the inner tobacco leaves, the upper part of the tobacco leaves needs to be removed first. This is not only labor-intensive but also inefficient. Utility Model Content

[0003] To address the aforementioned problems, the purpose of this invention is to provide a multi-point sampling device for finished tobacco sheets.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows: a multi-point sampling device for finished tobacco flakes, comprising a base plate and columns supported at both ends of the base plate. A horizontal beam is fixed at the top of the columns supported at both ends of the base plate. A hollowed-out slide is provided in the center of the beam. A vertical guide sleeve is slidably arranged in the slide of the beam. A spiral conveying cylinder is vertically inserted through the guide sleeve. A spiral auger is provided in the spiral conveying cylinder. The spiral auger is driven to rotate by a reduction motor at the upper end of the spiral conveying cylinder. A downwardly inclined discharge cylinder is fixed on one side of the upper end of the spiral conveying cylinder and communicates with the upper end of the spiral conveying cylinder.

[0005] Furthermore, a sliding sleeve is fitted around the outside of the crossbeam, and a guide sleeve vertically penetrates the sliding sleeve.

[0006] Furthermore, a locking bolt for clamping the screw conveyor cylinder is provided on one side of the top of the guide sleeve.

[0007] Furthermore, the lower end of the spiral conveyor cylinder is equipped with an annular blade structure.

[0008] Furthermore, the top of the geared motor is equipped with a power plug for electrical connection to an external power source.

[0009] Furthermore, the base plate is a square plate structure, and the two columns are fixed at the two ends of the diagonal of the square plate structure.

[0010] Furthermore, the lower surface of the base plate is padded with multiple anti-slip pads.

[0011] With the above settings, when using this utility model, if tobacco leaf samples are taken at multiple points along the diagonal direction of the carton, move to the sampling point, loosen the locking bolt, insert the spiral conveyor cylinder downward into the carton, start the reduction motor, the reduction motor works, and drive the spiral auger inside the spiral conveyor cylinder to rotate, thereby driving the tobacco leaves at the lower end of the spiral conveyor cylinder to the downward-sloping discharge cylinder through the rotation of the spiral auger, and finally discharge them into the sample bottle through the downward-sloping discharge cylinder.

[0012] Sampling using the above method eliminates the need to remove the top layer of tobacco leaves first, effectively preventing the inner tobacco leaves from losing moisture due to the lack of covering after the top layer is removed. This avoids affecting the test results due to moisture evaporation. Furthermore, the entire sampling process does not require manual handling, effectively preventing contact between the tobacco leaves and the sampling personnel's hands and avoiding contamination of the tobacco leaves at the sampling site. In addition, sampling using a spiral conveyor device results in higher sampling and transportation efficiency, effectively saving sampling time. Attached Figure Description

[0013] The present invention will now be further described with reference to the accompanying drawings.

[0015] Figure 2 This is a three-dimensional structural diagram of the present invention in use. Detailed Implementation

[0016] like Figure 1-2 As shown, a multi-point sampling device for finished tobacco flakes includes a base plate 1 and columns 2 supported at both ends of the base plate 1. A horizontal beam 3 is fixed at the top of the columns 2 supported at both ends of the base plate 1. A hollowed-out slide 4 is provided in the center of the beam 3. A vertical guide sleeve 5 is slidably arranged in the slide 4 of the beam 3. A spiral conveying cylinder 6 is vertically inserted in the guide sleeve 5. A spiral auger is arranged in the spiral conveying cylinder 6. The spiral auger is driven to rotate by a reduction motor 7 at the upper end of the spiral conveying cylinder 6. A downwardly inclined discharge cylinder 8 is fixed on one side of the upper end of the spiral conveying cylinder 6 and communicates with the upper end of the spiral conveying cylinder 6.

[0017] In order to make the sliding sleeve 9 slide smoothly on the crossbeam 3, the outer side of the crossbeam 3 is fitted with the sliding sleeve 9, the guide sleeve 5 vertically penetrates the sliding sleeve 9, and the top side of the guide sleeve 5 is provided with a locking bolt 10 for clamping the spiral conveyor cylinder 6. Tightening the locking bolt 10 can achieve the clamping and fixing of the spiral conveyor cylinder 6.

[0018] In order to allow the lower end of the spiral conveyor 6 to be smoothly inserted into the bottom of the box so as to effectively sample the tobacco leaves inside, the lower end of the spiral conveyor 6 is provided with an annular blade structure 11.

[0019] To facilitate power supply to the geared motor 7, a power plug 12 for electrical connection to an external power source is provided on the top of the geared motor 7.

[0020] The base plate 1 is a square plate structure, and two uprights 2 are fixed at the two ends of the diagonal of the square plate structure. The lower surface of the base plate 1 is padded with multiple anti-slip pads to facilitate the placement of cardboard boxes.

[0021] The working principle of this utility model is as follows: When sampling, multiple points along the diagonal of the carton are sampled. After moving to the sampling point, the locking bolt 10 is loosened, allowing the spiral conveyor cylinder 6 to move up and down, making it easy to insert the spiral conveyor cylinder 6 into the carton. The spiral conveyor cylinder 6 is inserted downward into the carton, and then the reduction motor 7 is started, which drives the spiral auger inside the spiral conveyor cylinder 6 to rotate. This causes the tobacco leaves at the lower end of the spiral conveyor cylinder 6 to be driven by the spiral auger to the downward-sloping discharge cylinder 8, and finally discharged into the sample bottle through the downward-sloping discharge cylinder 8.

[0022] The above description is merely an illustrative embodiment of this utility model and is not intended to limit the scope of this utility model. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of this utility model should fall within the protection scope of this utility model.
