[0025] Please also read Figures 1 to 4 The tobacco collecting mechanism provided by the utility model is now described. The tobacco collecting mechanism comprises a mounting shell 1, a telescopic driving member 2, a crank connecting rod assembly 3 and a front scraper arm 4. The telescopic driving member 2 is arranged in the mounting shell 1 along the front-to-back direction. A negative pressure collecting box 5 with a downward opening is arranged at the rear of the mounting shell 1. The crank connecting rod assembly 3 is connected to the front end of the telescopic driving member 2 and extends through the mounting shell 1 to the front side of the mounting shell 1. The front scraper arm 4 is connected to the front end of the crank connecting rod assembly 3. The front scraper arm 4 can swing horizontally under the drive of the crank connecting rod assembly 3 and push the tobacco backward to approach the negative pressure collecting box 5.

[0026] Compared with the prior art, the tobacco collecting mechanism provided in the present embodiment utilizes the telescopic driving member 2 to drive the crank connecting rod assembly 3 to move, thereby driving the front scraper arm 4 to swing horizontally, and the front scraper arm 4 is used to scrape the tobacco on the front side to the bottom of the mounting shell 1, so that the negative pressure collection box 5 can perform negative pressure suction on the collected tobacco, thereby realizing effective collection of the tobacco. This structure can conveniently collect and push the tobacco on the tray to the bottom of the negative pressure collection box 5, thereby improving the cleaning efficiency of the tobacco, ensuring the cleanliness above the tray, and avoiding the breeding of tobacco insects.

[0027] In actual use, after the distribution vehicle stops, the tobacco collection mechanism is placed on the tray and started. The mounting shell 1 can move forward, the front scraper arm 4 can swing horizontally to the rear side, and drive the tobacco to gather backward to approach the negative pressure collection box 5, and then the tobacco is uniformly collected into the negative pressure collection box 5 under the action of negative pressure suction. After that, the tobacco collection mechanism continues to move along the tray, gradually and effectively cleans the tobacco on the tray, eliminating the tedious manual wiping and avoiding safety hazards.

[0028] In one possible implementation, see Figures 1 to 4 The crank-connecting rod assembly 3 includes a guide rail 31, a sliding block 32, a connecting rod 33 and a crank 34. The guide rail 31 is connected to the mounting shell 1 along the front-to-back direction. The sliding block 32 is slidably mounted on the guide rail 31 and connected to the sliding block 32. The crank 34 is rotatably connected to the mounting shell 1 and is located on the front side of the guide rail 31. The crank 34 is connected to the sliding block 32 through the connecting rod 33. The front scraper arm 4 is connected to the crank 34 and can swing horizontally driven by the crank 34.

[0029] In this embodiment, the guide rail 31 can guide the sliding block 32 in the moving direction. Under the driving action of the telescopic drive member 2, the sliding block 32 moves forward along the guide rail 31, and then uses the connecting rod 33 to output power to the crank 34. The crank 34 produces a horizontal swing, and then drives the front scraper arm 4 connected to it to swing horizontally, pushing the tobacco to the bottom of the mounting shell 1, so that the negative pressure collection box 5 can effectively collect the tobacco. The lower edge of the front scraper arm 4 is in effective contact with the top surface of the tray to avoid tobacco residue on the tray, thereby ensuring the comprehensive removal of the tobacco.

[0030] In one possible implementation, see Figures 1 to 4 The crank 34 is rotatably connected to the mounting shell 1 through the vertical shaft 35, the crank 34 is connected to the front scraper arm 4 through the connecting arm 6, the connecting arm 6 is fixedly connected to the front scraper arm 4, and the connecting arm 6 and the front scraper arm 4 can swing horizontally synchronously under the drive of the crank 34.

[0031] In this embodiment, during installation, the crank 34 is rotatably connected to the mounting shell 1 via the vertical shaft 35, so that the crank 34 can swing horizontally around the vertical shaft 35 driven by the connecting rod 33. The crank 34 is connected to the front scraper arm 4 via the connecting arm 6, so that the front scraper arm 4 can swing horizontally synchronously with the crank 34, so as to effectively push the tobacco, so that the tobacco is effectively gathered on the surface of the tray and sent to the bottom of the mounting shell 1, so as to avoid tobacco residue on the surface of the tray.

[0032] For some examples, see Figures 1 to 4 The connecting arm 6 includes a first rod body 61 and a second rod body 62. The first rod body 61 is fixedly connected to the upper edge of the front scraping arm 4. The rear end of the first rod body 61 is connected to the crank 34. The front end of the second rod body 62 is connected to the front end of the first rod body 61. The rear end of the second rod body 62 is rotatably connected to the vertical shaft 35. The first rod body 61, the second rod body 62, the front scraping arm 4 and the crank 34 can swing horizontally around the vertical shaft 35 synchronously.

[0033] In this embodiment, the connecting arm 6 is in the form of a combination of a first rod body 61 and a second rod body. The first rod body 61 is fixedly connected to the upper edge of the front scraping arm 4, and the rear end of the first rod body 61 is connected to the crank 34. The front end of the second rod body 62 is connected to the front end of the first rod body 61. The first rod body 61, the second rod body 62 and the crank 34 can form a stable triangular structure to ensure effective driving of the front scraping arm 4. The above structure. The above connecting arm 6 has a relatively simple structure, which can not only save material consumption, but also ensure the driving effect on the front scraping arm 4, and improve the smoothness of the structural action.

[0034] For some examples, see Figures 1 to 4 A strip vertical plate 7 for installing the guide rail 31 is provided in the mounting shell 1. The guide rail 31 is connected to the outer side of the strip vertical plate 7. A mounting seat 71 is provided on the front side of the guide rail 31. The vertical shaft 35 penetrates the mounting seat 71 along the up and down directions. A clearance cavity 72 for avoiding the second rod body 62 is provided on the front end surface of the mounting seat 71. The vertical shaft 35 penetrates the clearance cavity 72. A limiting surface extending obliquely toward the outside and forward is provided on the side of the clearance cavity 72 away from the central axis of the mounting shell 1. The limiting surface is used to limit the swing amplitude of the second rod body 62.

[0035] In this embodiment, the strip vertical plate 7 extends in the front-to-back direction, and the plate surface is arranged perpendicular to the inner bottom wall of the mounting shell 1, which can provide an installation basis for the guide rail 31. The two ends of the guide rail 31 are connected to the outer side of the strip vertical plate 7 through a connecting plate, which improves the reliability of the structural connection.

[0036] The front end of the guide rail 31 is provided with a mounting seat 71, and the mounting seat 71 is provided to facilitate the installation of the vertical shaft 35. The clearance cavity 72 on the mounting seat 71 provides a clearance space for the second rod body 62, and the vertical shaft 35 passes through the clearance cavity 72, and forms a rotational fit with the second rod body 62 and the crank 34, respectively, so that the connecting arm 6 and the crank 34 form a synchronous rotation effect around the vertical shaft 35, thereby realizing the effective drive of the front rotation scraper arm 4.

[0037] On this basis, the side wall of the clearance cavity 72 away from the mounting shell 1 forms a limiting surface, which can limit the swing amplitude of the second rod body 62 to the outside, and avoid structural jamming caused by excessive swing angle of the front scraper arm 4.

[0038] In one possible implementation, see Figures 1 to 4 A connecting rod 33 is provided on the upper and lower sides of the same sliding block 32 , and the front side of each connecting rod 33 is connected to the front scraping arm 4 through a crank 34 , and the connecting arm 6 is located between the upper and lower cranks 34 .

[0039] In this embodiment, the two connecting rods 33 are respectively located on the upper and lower sides of the same sliding block 32, and are symmetrically arranged on the upper and lower sides of the sliding block 32. Each connecting rod 33 is connected to a crank 34, and the connecting arm 6 is driven by the upper and lower cranks 34, thereby avoiding uneven force caused by the connecting arm 6 being driven by only one crank 34 at the top or the bottom, and improving the smoothness of the swing of the front scraper arm 4.

[0040] For some examples, see Figures 1 to 4 The crank 34 is an isosceles triangular plate-shaped component. The vertical shaft 35 is rotatably connected to the top corner of the crank 34. The connecting rod 33 and the connecting arm 6 are connected to the two bottom corners of the crank 34 one by one. The connecting arm 6 is located on the outside of the connecting rod 33.

[0041] In this embodiment, the crank 34 is a triangular plate-shaped member and is in an isosceles triangle structure, having one vertex angle and two base angles, and the angles of the two base angles are equal. The vertical shaft 35 is set through the crank 34 and is set near the vertex angle of the crank 34. The connecting rod 33 and the connecting arm 6 are connected to the positions of the crank 34 near the two base angles in a one-to-one correspondence, so that the crank 34 can drive the front scraper arm 4 to swing smoothly, ensuring the pushing effect on the tobacco.

[0042] In one possible implementation, see Figures 1 to 4 There are two groups of crank-connecting rod assemblies 3, which are symmetrically arranged on both sides of the telescopic driving member 2 and are respectively connected to the telescopic driving member 2 through the connecting bent rod 21. There are also two front scraping arms 4, which are connected to the front sides of the two groups of crank-connecting rod assemblies 3 in a one-to-one correspondence. The two front scraping arms 4 can swing toward each other under the drive of the crank-connecting rod assemblies 3. The two groups of crank-connecting rod assemblies 3 are symmetrically arranged on both sides of the telescopic driving member 2, forming a public drive for the two front scraping arms 4 on the front side, so that the two front scraping arms 4 can swing toward each other synchronously so as to push the tobacco shreds on the front side to the bottom of the mounting shell 1, thereby expanding the cleaning area and improving the cleaning speed.

[0043] In one possible implementation, see Figures 1 to 4 The front scraper arm 4 extends in the horizontal direction, and a curved cavity 41 is provided on one side of the front scraper arm 4 close to the central axis of the mounting shell 1. The curved cavity 41 is provided through the extending direction of the front scraper arm 4 and is used to accommodate tobacco. The front scraper arm 4 extends a certain length and has a curved cavity 41 for accommodating tobacco. The arrangement of the curved cavity 41 can enhance the collection capacity of the front scraper arm 4 for tobacco, so that it has a larger accommodation space.

[0044] For some examples, see Figures 1 to 4 The lower edge of the front scraper arm 4 is connected with a flexible strip 42, which can flexibly contact the top surface of the tray. The flexible strip 42 at the lower edge of the front scraper arm 4 can press against the top surface of the tray to ensure thorough removal of the tobacco and avoid the loss of tobacco.

[0045] The above-mentioned tobacco collecting mechanism utilizes the telescopic driving member 2 to drive the crank connecting rod assembly 3 to move, and then drives the front scraper arm 4 to swing horizontally, and the tobacco on the front side is scraped to the bottom of the mounting shell 1 by the front scraper arm 4, so that the negative pressure collection box 5 can perform negative pressure suction on the collected tobacco, thereby realizing effective collection of the tobacco. This structure can conveniently collect and push the tobacco on the tray to the bottom of the negative pressure collection box 5, thereby improving the cleaning efficiency of the tobacco, ensuring the cleanliness above the tray, and avoiding the breeding of tobacco insects.

[0046] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
