[0050] like Figures 1 to 5 As shown, a transmission device for a cabbage harvester comprises:

[0051] Rack 1,

[0052] A primary transmission mechanism 2, comprising a primary power element and a plurality of rollers 21 arranged in parallel, wherein the primary power element is connected to the frame 1, the rollers 21 are rotatably connected to the frame 1, and each of the rollers 21 is transmission-connected to the primary power element;

[0053] A secondary transmission mechanism 3 is obliquely arranged at the rear of the primary transmission mechanism 2, and comprises a secondary power element, a driving sprocket 31, a driven sprocket 32, a chain plate transmission belt 33 and a plurality of push rod portions 34, wherein the secondary power element is transmission-connected with the driving sprocket 31, the driving sprocket 31 and the driven sprocket 32 ​​are rotationally connected to the frame 1, the chain plate transmission belt 33 is tensioned and connected between the driving sprocket 31 and the driven sprocket 32, and a plurality of push rod portions 34 are arranged at intervals on the chain plate transmission belt 33, and the push rod portions 34 are perpendicular to the plate surface of the chain plate 331 of the chain plate transmission belt 33;

[0054] Two optical axes 4 are arranged below the secondary conveying mechanism 3 and connected to the frame 1, and the two optical axes 4 are arranged at intervals, and a conveying channel 7 between the optical axis 4 and the secondary conveying mechanism 3 is provided for cabbage to pass along the extension direction of the optical axis 4;

[0055] The collecting bag 6 is arranged at the rear of the conveying channel 7 and is used for collecting the cabbages conveyed through the conveying channel 7 .

[0056] The rollers 21 of the primary conveying mechanism 2 are arranged horizontally, and the direction and speed of each roller 21 are the same. The primary conveying mechanism 2 is used to convey the harvested cabbage horizontally backward, that is, to the secondary conveying mechanism 3. The side of the secondary conveying mechanism 3 away from the primary conveying mechanism 2 is higher than the side close to the primary conveying mechanism 2. In the conveying direction of the primary conveying mechanism 2, the secondary conveying mechanism 3 conveys the cabbage obliquely upward.

[0057] The secondary conveying mechanism 3 includes a chain plate type conveyor belt assembly, and its push rod part 34 is used to push the cabbage conveyed from the primary conveying mechanism 2. After the cabbage is conveyed from the primary conveying mechanism 2, the push rod part 34 on the secondary conveying mechanism 3 pushes the back of the cabbage to convey the cabbage along the extension direction of the optical axis 4. The surface of the optical axis 4 is flat and smooth, and the cabbage can be smoothly conveyed upward from the surface of the optical axis 4. When the cabbage is conveyed in the conveying channel 7, the cabbage is located between the chain plate conveyor belt 33 and the optical axis 4, and there is a certain gap between the cabbage and the chain plate conveyor belt 33 to prevent the chain plate conveyor belt 33 from squeezing the cabbage.

[0058] The two optical axes 4 arranged at intervals support the bottom of the cabbage to prevent the cabbage from falling off the optical axes 4 during transportation.

[0059] The cabbages conveyed through the conveying channel 7 are smoothly collected in the collecting bag 6, so as to be conveniently transported in bags.

[0060] In some embodiments, the push rod 34 is a retractable structure. The retractable direction of the push rod 34 is perpendicular to the plate surface of the chain plate 331 of the chain plate transmission belt 33. The push rod 34 will shrink when squeezed by external force, that is, when the end of the push rod 34 just squeezes the cabbage, the push rod 34 shrinks to avoid squeezing the cabbage.

[0061] In some embodiments, the push rod portion 34 includes two push rod units and a roller 341 arranged at intervals, the push rod unit includes a linear bearing 342 and a push rod 343, one end of the push rod 343 is inserted into the linear bearing 342, the roller 341 is rotatably connected to one end of the two push rods 343 away from the linear bearing 342, the chain plate 331 on the chain plate transmission belt 33 for installing the push rod portion 34 is provided with a first linear bearing mounting hole and a second linear bearing mounting hole, and the two linear bearings 342 are correspondingly installed in the first linear bearing mounting hole and the second linear bearing mounting hole. In this embodiment, the roller 341 can roll and avoid along the surface of the cabbage, which can further reduce the damage of the push rod portion 34 to the cabbage. When the push rod 34 squeezes the cabbage, the push rods 343 of the two push rod units move along the linear bearings 342. The push rods 343 move toward the inside of the chain plate transmission belt 33 under the action of the linear bearings 342, so that the rollers 341 move toward the chain plate transmission belt 33. The rollers 341 contact the surface of the cabbage and roll away from the surface of the cabbage. With the transmission of the chain plate transmission belt 33, until the next push rod 34 reaches the position of the cabbage again, the cabbage is pushed onto the optical axis 4, and the cabbage is transported. Because the push rod 34 is located below the chain plate transmission belt 33 when pushing the cabbage, the push rod 34 can still recover under the action of the self-weight of the roller 341 after contraction.

[0062] In some embodiments, the push rod unit further includes a limit block 344, which is sleeved on the push rod 343, and the limit blocks 344 on the two push rods 343 are at the same distance from the chain plate 331. The size of the limit block 344 is larger than the inner hole size of the linear bearing 342, and when the push rod unit is retracted, the limit block 344 can prevent the push rod unit from moving too far inside the chain plate transmission belt 33, thereby protecting the chain plate transmission belt 33.

[0063] In some embodiments, the chain plate transmission belt 33 is arranged parallel to the optical axis 4 on one side facing the optical axis 4, so that the cabbage can be smoothly transported between the chain plate transmission belt 33 and the optical axis 4.

[0064] In some embodiments, the distance between the side of the chain plate transmission belt 33 facing the optical axis 4 and the optical axis 4 is greater than 15 cm. This size setting can prevent larger cabbages from getting stuck between the chain plate transmission belt 33 and the optical axis 4.

[0065] In some embodiments, the distance between the push rod portion 34 and the optical axis 4 is less than 10 cm. That is, the distance between the end of the push rod portion 34 and the optical axis 4 is less than 10 cm, and the end of the push rod portion 34 refers to the end of the push rod portion 34 away from the conveyor belt of the chain plate 331. Setting the distance between the push rod portion 34 and the optical axis 4 to less than 10 cm can prevent the cabbage from sliding down the optical axis 4 from the end of the push rod portion 34 and leaving the conveying channel 7.

[0066] In some embodiments, the distance between the two optical axes 4 is 5-15 cm. This size setting can prevent the cabbage from falling between the two optical axes 4.

[0067] Finally, it should be noted that although the above embodiments have been described in the specification and drawings of this application, this does not limit the scope of patent protection of this application. All technical solutions generated by replacing or modifying equivalent structures or equivalent processes based on the essential concept of this application using the contents recorded in the specification and drawings of this application, as well as directly or indirectly implementing the technical solutions of the above embodiments in other related technical fields, are included in the scope of patent protection of this application.
