Description

Technical Field

[0001] The utility model relates to the technical field of rapeseed harvesting, in particular to a reel for a rapeseed combine harvester. Background Art

[0002] Rapeseed is another name for the axis rapeseed. European rapeseed is a herbaceous crop of the cruciferous family and the genus Brassica. The stem is upright and branched, with only a few scattered bristles on young leaves; the petiole is 2.5-6 cm long and has lobes at the base; the middle and upper stem leaves gradually change from oblong elliptical to lanceolate, with a heart-shaped base and clasping the stem. The raceme is corymbose; the pedicel is 6-12 mm long; the sepals are ovate and the petals are light yellow. The siliques are linear, with thin beaks of the fruit petals; the fruit pedicel is about 2 cm long. The seeds are spherical, yellow-brown, often black near the hilum, and have a reticular nest. The flowering period is from March to April, and the fruiting period is from April to May. When the existing rapeseed is harvested, most of the existing machines are prone to cause the seed pods to crack when harvesting rapeseed, resulting in great waste. In addition, most of the existing harvesting platforms cannot harvest effectively, and it is easy to miss the rapeseed on the edge of the harvesting platform, resulting in low harvesting efficiency and affecting work progress. In order to solve the above problems, a technical solution is disclosed in Patent No.: CN202123420992.8. Although the technical solution can solve the above problems, there are still some problems in use. The structure of the general harvesting platform is There are many parts in the harvesting table. In order to harvest rapeseed, a reel mechanism is set on the harvesting table to press the rapeseed to the cutting knife for cutting. The general structure of the reel mechanism contains tines, and the function of the tines is to push the upright rapeseed stems and leaves to the inside of the cutting table. The tines are generally fixed on the reel board. However, since the stems and leaves of rapeseed are relatively hard and have many branches, when the fixed tines push the stems and leaves to the cutting position and cut them off, the tines are easy to get caught on the stems and leaves of the rapeseed, causing them to be pushed out of the harvesting table, and then causing the stems and leaves to be thrown out, thereby affecting the threshing and processing efficiency.

[0003] Based on this, the utility model designs a reel for a rapeseed combine harvester to solve the above problems. Utility Model Content

[0004] The utility model aims to provide a reel for a rapeseed combine harvester to solve the problem in the background art that the cut stems and leaves are easily entangled and thrown out of the cutting table by the tower teeth during cutting.

[0023] A cavity 9 is provided in the plowing plate 8, and the tooth mechanism 12 is located in the cavity 9, so as to facilitate the control of the contraction of the tooth mechanism 12 and avoid scratching the stems and leaves of the rapeseed.

[0024] Among them, the floor tooth mechanism 12 and the cam 11 are movably connected, the floor tooth mechanism 12 includes a slide bar 13, a spring 14 and a protrusion 15, the slide bar 13 is slidably connected in the plowing plate 8, the slide bar 13 is sleeved with a spring 14, and a protrusion 15 is installed at one end of the spring 14, and the protrusion 15 and the cam 11 are movably engaged, preventing the stems and leaves from being thrown out of the harvesting platform 1 during use, thereby further improving the convenience of using the equipment.

[0025] Among them, a transmission mechanism 19 is provided between the feeding assembly 18 and the rotating rod 5, and the transmission mechanism 19 includes a hydraulic rod 20, a slider 21, a speed regulating box 22 and a transmission wheel. The hydraulic rod 20 is installed on the harvesting platform 1, and a slider 21 is installed at one end of the hydraulic rod 20. The slider 21 is slidably connected to the harvesting platform 1, and a speed regulating box 22 is installed on the harvesting platform 1. The speed regulating box 22 and the feeding assembly 18 are transmission connected, and the speed regulating box 22, the slider 21 and the rotating rod 5 are all installed with transmission wheels, and multiple transmission wheels are transmission connected; it is convenient to carry out subsequent processing of the harvested materials.

[0026] The rack 4 is semi-circular and is located at the front side of the fixed disk 3, which facilitates the contraction of the floor gear mechanism 12, while maintaining the ability to move the stems and leaves when in use and contract when not in use.

[0027] Working principle:

[0028] When working, the position of the reel plate 8 is changed by adjusting the length and length of the telescopic arm 2, so that the equipment is more convenient to use. In the process of adjustment, the extension and retraction of the hydraulic rod 20 is controlled, and the slider 21 is moved at the same time. At this time, the three transmission wheels always maintain a transmission state, thereby further improving the adjustment convenience of the equipment and avoiding the need for manual disassembly and adjustment. When the equipment is working, the feeding assembly 18 controls the rotation of the rotating rod 5 through the transmission mechanism 19. When the rotating rod 5 rotates, the fixed plate 3 rotates at the same time. At this time, the fixed plate 3 drives the gear 17 on its upper side to make a circular motion with the rotating rod 5 as the center. When the reel plate 8 moves to the front side, the gear 17 and the rack 4 are meshed. At this time, the gear 17 rotates under the drive of the rack 4, and the cam 11 rotates at the same time, and the torque The spring 16 is also gradually compressed. When the cam 11 rotates, the cam 11 squeezes the protrusion 15, so that the slide bar 13 gradually extends out of the outside of the reed plate 8. At the same time, the spring 14 is compressed. As the mounting plate 6 rotates, the extended slide bar 13 can effectively swing the stems and leaves to the inside of the cutting table, thereby completing the cutting. As the rotating rod 5 rotates, when the material fluctuates to the feeding assembly 18, the gear 17 and the rack 4 are disengaged. At this time, the torsion spring 16 and the spring 14 are reset, and then the slide bar 13 is quickly retracted into the cavity 9, so that one side of the reed plate 8 is flat, thereby avoiding too many branches of the stems and leaves, causing the slide bar 13 to throw the material out of the cutting table, and the equipment can be repeatedly moved for cutting. The structure of the equipment is simple and practical, which further improves its harvesting efficiency and quality and prevents the situation of being thrown out during harvesting.
