Technical Field

[0001] The utility model belongs to the technical field of agricultural machinery, in particular to a material direct current type laying, cutting and drying platform. Background Art

[0002] When the harvesting platform is harvesting crops, it is inevitable that the sprocket will be entangled with grass, especially the passive sprocket will be entangled with grass, which affects the harvesting effect of the whole machine. In order to solve the problem of grass entanglement, technical personnel in this field have also made many improvements. For example, in order to prevent the passive sprocket of the straw chain from being entangled with grass, some mowing and drying platforms have star wheels at the corners, and some have guide plates. However, both methods will protrude at the edge of the harvesting platform, causing the crops to be pushed forward, and the discharge of materials will be blocked. Therefore, in terms of preventing grass entanglement, further improvements need to be made to the mowing and drying platforms in the prior art. Summary of the invention

[0003] The utility model provides a material direct current laying and cutting and drying platform, so as to prevent the passive wheel from being entangled with grass and ensure smooth material discharge on the cutting and drying platform without obstruction.

[0005] Furthermore, the chain between the passive reel-pulling wheel and the active reel-pulling wheel is at an inclined angle.

[0006] Furthermore, a reel chain slot plate is respectively installed on the frame at the upper and lower sides of the reel chain; and the right side end of the reel chain slot plate is an arc-shaped slot plate.

[0007] Furthermore, in the reed chain slot plate, a baffle is installed on the uppermost reed chain slot plate.

[0008] Furthermore, the uppermost reel driving wheel has a larger number of teeth than the lower reel driving wheel.

[0009] Furthermore, the reed chain at the lowest side is shorter than the reed chain at the upper side, and the length of the reed chain slot plate at the lowest position is shorter than the reed chain slot plate at the upper side.

[0011] Furthermore, the rear end of the crop divider assembly is installed as a star wheel arranged up and down.

[0012] Beneficial effects of the utility model:

[0013] In the utility model, because the right end of the reed chain slot plate is arc-shaped, when the reed chain runs to this position, the reed teeth will be hidden in the reed chain slot plate, and will not carry crops backward, thereby achieving the effect of preventing grass entanglement. A reed transition wheel is added to the reed wheel, and the reed transition wheel and the reed driving wheel make the front end of the reed chain in a straight state. Due to the existence of the reed transition wheel, the reed driven wheel moves backward, so that the reed chain runs backward after running to the right side; there will be no obstructions protruding forward, the material discharge can be smoother, and the effect of preventing grass entanglement is better.

DETAILED DESCRIPTION

[0022] The technical solution of the present invention is further explained below through specific implementation methods.

[0023] Referring to the attached drawings, the utility model provides a material direct current laying and cutting and drying platform, including a frame assembly 1, characterized in that it also includes a plurality of longitudinally arranged groups of reed assemblies; the reed assemblies include a reed chain 2 and a reed wheel; the reed wheel is divided into a reed driving wheel 3, a reed transition wheel 4, and a reed passive wheel 5; the reed chain 2 is provided with reed teeth; the reed driving wheel 3 is mounted on a hexagonal vertical shaft 6, the reed transition wheel 4 and the reed passive wheel 5 are respectively mounted on the frame, and the reed transition wheel 4 and the reed driving wheel 3 install the front end of the reed chain 2 in a horizontal state. The rear end of the reed chain 2 is a chain between the reed passive wheel 5 and the reed driving wheel 3, which is at an inclined angle.

[0024] The upper and lower sides of the reed chain are respectively provided with reed chain slot plates 7 on the frame; the right end of the reed chain slot plate 7 is an arc-shaped slot plate 7.1. Among the reed chain slot plates 7, a baffle plate 8 is provided on the uppermost reed chain slot plate 7.

[0025] The uppermost reel driving wheel 3 has a larger number of teeth than the lower reel driving wheel 3. In this embodiment, four groups are arranged longitudinally, with four rows of reel chains 2, and the reel driving wheels 3 in the uppermost row of the four rows of reel chains 2 have a larger number of teeth than the reel driving wheels 3 in the lower three rows, so that the upper reel chain has a high rotation speed, which can make the crops reach an inclined conveying state, so that the crops can be better placed in a horizontal state, which is convenient for subsequent crop picking.

[0026] The lowest reed chain 2 is shorter than the upper reed chain 2, and the lowest reed chain slot plate 7 is shorter than the upper reed chain slot plate 7. The lowest reed chain 2 is shorter than the upper three reed chains 2, so that the crops are already in an inclined state when they are discharged to the discharge side, and the lower reed chain slot plate 7 is short, which can avoid the roots and will not push the crops forward, so that the crops can be laid more evenly and prevent the crops from being laid in a mess.

[0027] The left side of the mowing platform is equipped with a vertical knife assembly 9, which transmits power through a vertical knife swing arm 17; and a shield 10 is installed between the vertical knife assembly 9 and the cutting platform; the front side of the mowing platform is equipped with a crop divider assembly 11; on the lower side frame of the crop divider assembly, a horizontal knife assembly 12 is installed, and the horizontal knife assembly transmits power through a horizontal knife swing arm 18. The rear end of the crop divider assembly 11 is equipped with a star wheel 16 arranged up and down. The horizontal knife assembly and the vertical knife assembly can use existing mature technology.

[0028] When the utility model is in use:

[0029] The external power is input into the transmission box 14 through the power input wheel 13, and the transmission box 14 transmits the power to the hexagonal vertical shaft 6 through the sprocket. The hexagonal vertical shaft 6 drives the active wheel 3 to rotate, and drives the transition wheel 4 and the passive wheel 5 to rotate through the rice-pulling chain 2. The upper and lower star wheels 16 of the rice divider assembly 11 rotate under the drive of the rice-pulling chain 2 teeth to play the role of shifting crops. The power of the cutter comes from the transmission box, and the power is transmitted to the vertical cutter through other sprockets and the vertical cutter transmission shaft 15. After the cutter cuts the crop, the crop is shifted to the right side under the joint action of the rice-pulling chain 2 and the star wheel 16, and laid flat on the ground.
