Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of rapeseed threshing, in particular to a threshing component of a rapeseed combine harvester. Background Art
[0002] When the segmented harvesting method is used in actual production, the loss rate of rapeseed is relatively small, and the oil content of rapeseed is relatively high, but there are many processes and the cost is relatively high. In addition, the existing rapeseed thresher has poor threshing effect and a low rapeseed separation rate. To solve the above problems, a technical solution is disclosed in Patent No.: CN202322501495.3. Although the technical solution can thresh rapeseed, there are still some problems in the use of the technical solution. When threshing, the equipment separates the rapeseed rhizomes and transports them to the conveyor belt through a slide, and then adsorbs them by a vacuum cleaner and then discharges them. However, since the diameter of rapeseed is small and the weight is light, when the equipment is vacuuming, it is easy to adsorb the rapeseed and debris into the vacuum cleaner together, resulting in incomplete separation, thereby reducing the use efficiency of the equipment.
[0003] Based on this, the utility model designs a threshing component of a rapeseed combine harvester to solve the above problems. Utility Model Content
[0004] The utility model aims to provide a threshing assembly for a rapeseed combine harvester, so as to solve the problem of rapeseed being easily misadsorbed and incompletely separated during the separation process proposed in the above background technology.
[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0006] A threshing assembly of a rapeseed combine harvester comprises a box body, two springs are fixedly connected to the box body, a filter screen is fixedly connected between the two springs, two fixed rods are fixedly connected to the filter screen, a moving wheel is installed at one end of the fixed rod, track plates are installed on both sides of the box body, the moving wheel and the track plate are movably connected, two columns are fixedly connected to the box body, a protrusion is fixedly connected to the column, a driving motor is installed on the filter screen, a rotating rod is fixedly connected to the output end of the driving motor, two cams are installed on the rotating rod, the cam and the protrusion are movably connected, a plurality of dispersion mechanisms are arranged in the filter screen, the plurality of dispersion mechanisms are transmission connected, one of the dispersion mechanisms is transmission connected to the rotating rod, a secondary screening chamber is arranged inside the box body, the secondary screening chamber is located at one end of the filter screen, and a threshing assembly is arranged in the box body.
[0007] Preferably, the two springs have different lengths, and the filter is semicircular and inclined.
[0008] Preferably, connecting plates are fixedly connected to both sides of the filter screen, and the connecting plates are soft rubber plates.
[0009] Preferably, the dispersion mechanism comprises a rotating column, a lever and a pull plate, the filter screen is rotatably connected to the rotating column, a plurality of levers are mounted on the rotating column, and a pull plate is mounted on one end of the lever.
[0010] Preferably, the threshing assembly is located on a double-rod threshing head, and the two threshing heads are meshed with each other.
[0011] Compared with the prior art, the beneficial effects of the utility model are:
[0012] 1. The utility model places the straw material to be threshed into the box, and the threshing component stirs and thres the straw, and the threshing component includes two threshing heads that are meshed, so the threshing effect is better and the threshing efficiency is higher. After the material is threshed, the rapeseed and straw fall onto the filter at the same time. At this time, the driving motor is turned on, and the driving motor drives the rotating rod and the rotating column to rotate at the same time. When the rotating rod rotates, the cam and the protrusion contact, and the cam squeezes the protrusion to stretch the spring, and the filter rises at this time. In the process of rising, the moving wheel moves on the track plate, and the moving wheel is shaken by the path of the track plate. When the cam and the protrusion are separated, the spring rebounds, so that the moving wheel is shaken by the path of the track plate again, thereby accelerating the shaking efficiency of the filter, so that the rapeseed in the filter is quickly filtered, and then it is separated from the straw residue.
[0013] 2. When the rotating columns rotate at the same time, the lever drives the pulling block to rotate, and then the straw is pulled up. At the same time, it can be quickly separated from the rapeseed during the pulling up process. Since the filter is set inclined, the straw and rapeseed enter the secondary screening chamber for secondary screening after separation, thereby avoiding the presence of rapeseed in the straw when it enters the secondary screening chamber through the filter, further improving the separation efficiency and threshing quality of the equipment. When the equipment is fully working during use, the use of a vacuum cleaner can be reduced to complete the separation and threshing, further avoiding the occurrence of accidental suction during threshing, thereby improving the threshing efficiency and quality.

[0023] A threshing assembly of a rapeseed combine harvester comprises a box body 1, wherein two springs 2 are fixedly connected in the box body 1, a filter screen 3 is fixedly connected between the two springs 2, two fixed rods 5 are fixedly connected to the filter screen 3, one end of the fixed rod 5 is mounted with a moving wheel 6, track plates 7 are mounted on both sides of the box body 1, the moving wheel 6 and the track plate 7 are movably connected, two columns 8 are fixedly connected in the box body 1, a bump 9 is fixedly connected to the column 8, a driving motor 10 is mounted on the filter screen 3, a rotating rod 11 is fixedly connected to the output end of the driving motor 10, two cams 12 are mounted on the rotating rod 11, the cam 12 and the bump 9 are movably connected, a plurality of dispersion mechanisms 13 are arranged in the filter screen 3, the plurality of dispersion mechanisms 13 are transmission-connected, one of the dispersion mechanisms 13 is transmission-connected with the rotating rod 11, a secondary screening chamber 17 is arranged inside the box body 1, the secondary screening chamber is located at one end of the filter screen 3, and a threshing assembly 18 is arranged in the box body 1.
[0024] Among them, the two springs 2 have different lengths, and the filter screen 3 is semicircular and inclined; it is convenient for discharging the crushed straw and for the secondary screening chamber to perform secondary screening on it, and the semicircular setting can prevent rapeseed from splashing during threshing.
[0025] Wherein, both sides of the filter screen 3 are fixedly connected with connecting plates 4, and the connecting plates 4 are rubber soft plates; the use of the filter screen 3 is ensured to prevent the rapeseed from splashing during the threshing process.
[0026] Among them, the dispersion mechanism 13 includes a rotating column 14, a lever 15 and a pull plate 16. The filter screen 3 is rotatably connected to the rotating column 14, and multiple levers 15 are installed on the rotating column 14. A pull plate 16 is installed at one end of the lever 15; this is convenient for picking the straw, so that the rapeseed inside it can be quickly separated, and at the same time, the filter screen 3 can be prevented from being blocked during the threshing process.
[0027] The threshing assembly 18 is located in the double-rod threshing head, and the two threshing heads are meshed with each other, so as to improve the threshing efficiency and make it more convenient during threshing.
[0028] Working principle:
[0029] During operation, the straw material to be threshed is placed in the box body 1, and the threshing assembly 18 stirs and thres the straw, and the threshing assembly 18 includes two threshing heads that are engaged, so the threshing effect is better and the threshing efficiency is higher. After the material is threshed, the rapeseed and straw fall onto the filter screen 3 at the same time. At this time, the driving motor 10 is turned on, and the driving motor 10 drives the rotating rod 11 and the rotating column 14 to rotate at the same time. When the rotating rod 11 rotates, the cam 12 contacts the protrusion 9, and the cam 12 squeezes the protrusion 9 to stretch the spring 2. At this time, the filter screen 3 rises, and in the process of rising, the moving wheel 6 moves on the track plate 7, and the moving wheel 6 is shaken by the path of the track plate 7, and when the cam 12 and the protrusion 9 are disengaged, the spring 2 rebounds, so that the moving wheel 6 The path of the track plate 7 is shaken again, thereby accelerating the shaking efficiency of the filter 3, so that the rapeseed in the filter 3 is quickly filtered, and then separated from the straw residue. When the rotating column 14 rotates at the same time, the lever 15 drives the pulling block to rotate, and then the straw is pulled up. At the same time, in the process of pulling up, it can be quickly separated from the rapeseed. Since the filter 3 is inclined, the straw and rapeseed are separated and enter the secondary screening chamber 17 for secondary screening, so as to avoid the straw containing rapeseed when entering the secondary screening chamber 17 from the filter 3, further improving the separation efficiency and threshing quality of the equipment, and when the equipment is fully working during use, the use of the vacuum cleaner can be reduced to complete its separation and threshing, further avoiding the situation of accidental suction during threshing, thereby improving its threshing efficiency and quality.
