DETAILED DESCRIPTION

[0020] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation mode, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0021] Example 1

[0022] like Figure 1-3 As shown,

[0023] The tobacco storage cabinet comprises a spreading vehicle 3 for conveying tobacco shreds and a bottom bin 1 for storing tobacco shreds;

[0024] A material buffering device for a liftable tobacco storage cabinet comprises a buffering device connected to the side wall of a bottom bin 1, a detection device for detecting the thickness of tobacco in the bottom bin 1, and a controller respectively connected to the buffering device and the detection device by signal; the buffering device comprises a first buffer plate 6 for tobacco buffering and a lifting device for driving the first buffer plate 6 to rise and fall; the first buffer plate 6 is located between the material laying vehicle 3 and the bottom of the bottom bin 1.

[0025] Since the distance between the bottom of the bottom bin 1 and the laying vehicle 3 is about 1.68 meters, the first buffer plate 6 is set at a position 0.85 meters away from the bottom of the bottom bin 1, so that the tobacco 2 can first contact the first buffer plate 6, absorb part of the kinetic energy, and then fall into the bottom of the bottom bin 1.

[0026] The lifting device includes a guide rail 5 fixedly connected to the side wall of the bottom bin 1, a fixed block 51 fixedly connected to the guide rail 5, a sliding block 52 slidably connected to the guide rail 5, a first connecting rod 61 rotatably connected to the fixed block 51 at one end, a second connecting rod 62 rotatably connected to the sliding block 52 at one end, and a first sliding rod 63 respectively connected to the other end of the first connecting rod 61 and the other end of the second connecting rod 62; the middle part of the first connecting rod 61 is rotatably connected to the middle part of the second connecting rod 62; the first connecting rod 61 and the second connecting rod 62 are of equal length; the other end of the first connecting rod 61 is slidably connected to one end of the first sliding rod 63; the other end of the first sliding rod 63 is hinged to the other end of the second connecting rod 62; the first buffer plate 6 is fixedly connected to the first sliding rod 63 by bolts and nuts. The hinge point and the rotation connection of this application are both realized by pins, which are common knowledge and will not be repeated.

[0027] One end of the first sliding rod 63 connected to the first connecting rod 61 is provided with a strip slot, and the first connecting rod 61 slides in the strip slot through a pin shaft to prevent the first connecting rod 61 from getting stuck with the first sliding rod 63 when moving.

[0028] The lifting device also includes a cylinder 4 fixedly connected to the side wall of the bottom bin 1 ; the cylinder 4 is connected to the controller signal; and the cylinder rod of the cylinder 4 is hinged to the sliding block 52 .

[0029] The detection device includes a diffuse reflection photoelectric switch 8 fixedly connected to the guide rail 5; the diffuse reflection photoelectric switch 8 is used to detect the thickness of the tobacco in the bottom bin 1. The diffuse reflection photoelectric switch 8 is connected to the controller signal; the controller adopts a Siemens minicomputer, model S7-200;

[0030] The working process of the utility model is as follows:

[0031] The material spreading vehicle 3 conveys the tobacco 2 to the top of the bottom bin 1, and the tobacco 2 falls on the first buffer plate 6, and then falls on the bottom of the bottom bin 1. The diffuse reflection photoelectric switch 8 can detect the thickness of the tobacco 2 in the bottom bin 1 and transmit the signal to the controller. When the tobacco 2 in the bottom bin 1 is close to the first buffer plate 6, the distance is generally defined as 0.3 meters, and the controller sends a signal to the cylinder 4, and the cylinder rod of the cylinder 4 pushes the sliding block 52 outward, and the sliding block 52 drives the second connecting rod 62 to move outward, and the second connecting rod 62 drives the hinge point of the first connecting rod 61 and the second connecting rod 62 to move upward, and then the first connecting rod 61 and the second connecting rod 62 drive the first sliding rod 63 to move upward, and the first sliding rod 63 drives the first buffer plate 6 to move upward, so that the first buffer plate 6 can be prevented from being buried in the tobacco 2. It can also reduce the distance that the tobacco 2 falls and reduce the damage of the tobacco.

[0032] Example 2

[0033] The structure of this embodiment is basically the same as that of embodiment 1.

[0034] The difference is that

[0035] When the technical solution of Example 1 is implemented, it is found that after the tobacco 2 falls and is buffered by the first buffer plate 6, there is still a small amount of broken tobacco. In order to further improve it, if a layer of buffer is added, the effect will be better.

[0036] The buffer device further includes a second buffer plate 7 connected to the lifting device; the second buffer plate 7 is located below the first buffer plate 6 .

[0037] The lifting device further includes a third link 64 having one end hinged to the other end of the first link 61, a fourth link 65 having one end hinged to the other end of the second link 62, a fifth link 66 having one end hinged to the other end of the third link 64, a sixth link 67 having one end hinged to the other end of the fourth link 65, and a second sliding rod 68 having two ends respectively connected to the sixth link 67 and the fifth link 66; the third link 64 and the fourth link 65 are of equal length and hinged in the middle; the fifth link 66 and the sixth link 67 are of equal length and hinged in the middle;

[0038] The second sliding rod 68 is fixedly connected to the second buffer plate 7 .

[0039] One end of the second sliding rod 68 is hinged to the sixth connecting rod 67 ; the other end of the second sliding rod 68 is slidably connected to the other end of the fifth connecting rod 66 .

[0040] The added second buffer plate 7 can further buffer the tobacco shreds 2 falling into the bottom bin 1, reducing the amount of broken tobacco shreds 2. After observation, within two months of operation, the amount of broken tobacco shreds 2 per shift is 0.5 kg, which is almost negligible and has a significant effect.

[0041] Example 3

[0042] The structure of this embodiment is basically the same as that of embodiment 1.

[0043] The difference is that

[0044] The first buffer plate 6 and the second buffer plate 7 are both provided with downwardly inclined surfaces; the inclined surfaces are used to receive the tobacco shreds dropped from the spreading vehicle 3 .

[0045] The inclined plane is provided, and after the tobacco 2 falls on the inclined plane, the tobacco 2 can slide into the bottom bin 1, fully absorbing the kinetic energy of the tobacco 2 and reducing the amount of tobacco breakage.

[0046] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention.
