Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary tools for tobacco leaf inspection, in particular to a prying fork used for tobacco leaf inspection. Background Art

[0002] At present, the inspection and acceptance of imported tobacco leaves generally uses a combination of pry bars and manual prying and turning operations, which requires the cooperation of more than two people. It is very laborious and time-consuming. Each inspection and acceptance of imported tobacco leaves requires the inspection of more than 200 boxes. Relying on manpower for a long time to repeatedly pry and turn the tobacco leaves greatly consumes the physical strength of the operators and may cause muscle strain and other conditions. In actual operations, it is necessary to frequently arrange batch rotation operations.

[0003] When inspecting imported tobacco leaves, it is necessary to turn the boxed tobacco leaves over from a depth of 15cm-20cm to shake them loose, and check whether there are insects or mildew inside the tobacco leaves. Since it is done manually, the depth of prying and turning the tobacco leaves depends entirely on the subjective judgment of the operator. Sometimes the depth of prying and turning the tobacco leaves may not meet the requirements, which will have a certain impact on the accuracy of tobacco leaf acceptance. Moreover, since manual operation is slow, the tobacco leaves are exposed for a long time and are easily affected by the temperature and humidity of the surrounding environment, thus affecting the quality of tobacco leaf maintenance. The boxed tobacco raw materials are all stamped and packaged, and the tobacco leaves are pressed very tightly. It is very strenuous and time-consuming to loosen them manually. Male employees need two people to cooperate to operate smoothly, and female employees need three people to cooperate to operate smoothly. Utility Model Content

[0041] like Figures 1 to 5 As shown, the prying fork for tobacco leaf inspection of this embodiment is used for prying and checking the boxed tobacco leaves during the tobacco leaf inspection process. The prying fork includes:

[0042] Handle 100;

[0043] A support plate 200, which is a rectangular parallelepiped, and the lower end of the handle 100 is connected to the upper surface of the support plate 200;

[0044] A prying pad 300, the cross section of which is triangular, one bottom surface of which is connected to the rear side surface of the support plate 200; the prying pad 300 is located in the middle of the support plate 200, and a through hole 310 is provided on the end surface of the prying pad 300;

[0045] There are three fork tines 400, and the upper end of each fork tine 400 is connected to the lower surface of the support plate 200, and the intervals between all the fork tines are arranged at equal intervals.

[0046] When the prying fork for tobacco leaf inspection of the utility model is used, all the fork teeth 400 are inserted into the box body 500 along the vertical direction, and then the prying fork is rotated, one of the surfaces of the triangular prying pad 300 can be pressed on the supporting plane P1 of the edge of the box body 500, and the prying pad 300 can be used as a fulcrum for prying and turning over the tobacco leaves; the three fork teeth 400 can be easily inserted into the tobacco leaves, and the three fork teeth 400 can control the insertion depth of the tobacco leaves to pry over the tobacco leaves; the through hole 310 of the prying pad 300 can reduce the weight of the prying fork, which is convenient for the use of the prying fork; a single person holding the prying fork with both hands can accurately and easily turn over a large piece of tobacco leaves of 700×400mm, and the prying speed is also faster than that of bare hands.

[0047] The handle 100 includes a connecting rod 110 and a gripping member 120; the lower end of the connecting rod 110 is connected to the upper surface of the support plate 200; the gripping member 120 includes two fork pieces 121 and a gripping rod 122, the lower ends of the two fork pieces 121 are connected to the upper end of the connecting rod 110, the gripping rod 122 is located between the two fork pieces 121, and the two ends of the gripping rod 122 are respectively connected to the upper ends of the two fork pieces 121. The gripping member 120 is a hollow structure. When a single person holds the prying fork with both hands, the staff member holds the connecting rod 110 with one hand, and the staff member holds the gripping rod 122 with the other hand and then applies force to tilt the fork tines 400. The structure of the handle 100 is convenient for the staff member to use the prying fork.

[0048] The lower end of each fork tine 400 is an arc-shaped end portion 410. This structure facilitates the fork tine 400 to extend into the tobacco leaves and can prevent the lower end of the fork tine 400 from scratching surrounding people or objects during the taking process.

[0049] In order to facilitate processing and ensure that the prying pad 300 has a stable structure, the cross section of the through hole 310 is triangular.

[0050] The prying fork is made of stainless steel, so the prying fork has better rigidity.

[0051] The length L1 of the prying fork is 540 mm, the width W1 of the support plate 200 of the prying fork is 250 mm, the length L2 of the fork tines 400 is 190 mm, and the spacing K1 between adjacent fork tines 400 is 90 mm. The size of the prying fork can control the insertion depth of the fork tines 400 and ensure the prying speed of the prying fork.

[0052] The prying and turning fork is designed based on the principles of mechanics, integrating the characteristics of boxed tobacco raw materials and the basic requirements of imported tobacco inspection. After careful design, trial improvement and polishing, it is light, beautiful, economical and practical. One employee can pry and turn tobacco leaves efficiently and easily, saving time and effort, and the operation can be completed in one go. The accuracy and effect of prying and turning tobacco leaves are very good.

[0053] Example 1

[0054] 100 boxes of imported tobacco leaves were selected for the prying and turning experiment. It took two male employees 45 minutes to complete the operation manually. Specifically, two people operated at the same time, one person used an ordinary pry bar to turn the tobacco leaves, and the other person assisted by turning the tobacco leaves with both hands. After using the prying and turning fork of the utility model, a single person completed the operation in 35 minutes, which not only improved work efficiency but also reduced labor costs.

[0055] Example 2

[0056] 50 boxes of imported tobacco raw materials were selected for the prying and turning tobacco leaf test. Three female employees cooperated with manual operation and took 40 minutes to complete the operation. Specifically, three people operated at the same time, one person turned and pried the tobacco leaves, and two people assisted in turning the tobacco leaves over. After using the prying and turning fork of the utility model, a single person completed the operation in 33 minutes. The prying and turning fork has a suitable weight, is easy to operate, and is convenient and labor-saving.

[0057] Table 1 below compares the time taken to turn tobacco leaves in a tobacco box manually and by turning tobacco leaves with a fork:

[0058]

[0059] It can be seen from the test data that after using the prying fork of the utility model, the tobacco leaf inspection efficiency and manpower input are greatly improved.

[0060] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed in the present invention shall still be covered by the claims of the present invention.
