Description
Technical Field
[0001] The utility model relates to the technical field of threshers, in particular to a multifunctional thresher. Background Art
[0002] In plain areas, large harvesters are generally used to harvest rice after it matures. The rice can be threshed while harvesting to separate the rice grains from the straw. However, large harvesters are generally used in large and wide-ranging planting fields. In small breeding test fields, or in areas where it is not convenient for large harvesters to enter, such as terraces and areas with inconvenient transportation, large harvesters are not suitable. Therefore, in breeding test fields or terraces, manual rice harvesting is generally adopted, and then the harvested rice is threshed by a thresher.
[0003] When the existing rice thresher is in use, it usually adopts a separation drum and a screen drum. The operator holds a handful of rice and puts the rice between the threshing drum and the screen drum. The rice is threshed under the friction between the threshing drum and the screen drum. However, this method is not convenient for separating the threshed straw from the threshing drum and the screen drum. Generally, the straw is broken under the repeated friction between the separation drum and the screen drum and falls through the screen drum, resulting in more impurities in the rice. It is necessary to remove the impurities in the next process, which is time-consuming and labor-intensive. In addition, when the rice is continuously fed in for threshing, it is easy to form accumulation, resulting in a reduced threshing effect of the rice. Utility Model Content

[0023] Figures 1 to 6 Shown is an embodiment of the utility model.
[0024] Embodiment 1:
[0025] like Figure 1 , 2As shown in Figures 3 and 6, a multifunctional thresher comprises a thresher body 1, a thresher chamber 2 is arranged in the thresher body 1, a screen 3 is arranged horizontally in the thresher chamber 2, the screen 3 is recessed in the left-right direction to form two parallel first conveying grooves 4 and second conveying grooves 5, a partition plate 6 for separating the first conveying groove 4 and the second conveying groove 5 is arranged vertically between the first conveying groove 4 and the second conveying groove 5; an inlet 7 aligned with the first conveying groove 4 is arranged on the upper side of the thresher body 1; a first conveying groove 4 is provided with a rotating groove 7 along its length direction. There is a threshing shaft 8, and several first threshing pieces 9 are arranged around the threshing shaft 8 at a position aligned with the inlet 7. The cavity wall of the threshing chamber 2 is provided with a second threshing piece 10 that cooperates with the first threshing piece 9 at a position facing the first conveying trough 4; the first threshing piece 9 is arranged at an angle to push the material in the first conveying trough 4 to be conveyed from right to left when the threshing shaft 8 rotates. A through hole 11 connecting the first conveying trough 4 and the second conveying trough 5 is arranged on the left side of the partition plate 6, and a discharge port 12 aligned with the second conveying trough 5 is arranged on the rear side of the thresher body 1. When threshing, the crops such as rice, sorghum, and wheat that need to be threshed are placed from the inlet 7 into the first conveying trough 4, and the grains are separated from the stems by the cooperation of the first threshing piece 9 and the second threshing piece 10 in the first conveying trough 4. When separating, part of the stems will also be rolled into the first conveying trough 4. When these grains and stems rotate with the threshing shaft 8, the grains will fall to the bottom of the threshing chamber 2 through the screen 3, and the excess stems will move to the left side of the first conveying trough 4 with the rotation of the threshing shaft 8, and enter the second conveying trough 5 through the through hole 11, and be discharged from the discharge port 12. The first threshing piece 9 can drive the stems with grains to rotate with the threshing shaft 8, and beat them on the screen 3, so that the grains on the stems fall off. With the help of the second threshing piece 10, when it contacts the first threshing piece 9, the overlong stems can be broken to avoid the overlong stems from winding in the first conveying trough 4 and the second conveying trough 5 and causing blockage. In addition to conventional methods for threshing rice, such as holding the stalks of rice and putting one end of the rice ear into the inlet 7 for threshing, the utility model can also cut off the whole rice ear and directly throw it into the inlet 7 for threshing, such as sorghum ears, wheat ears, etc. can be directly cut off and thrown in. Not only can a variety of crops be threshed, but also a variety of methods can be used for threshing, which improves the versatility of the entire device.
[0026] The discharge port 12 is arranged near the right end of the thresher body 1, and a first spiral conveying shaft 13 is arranged in the second conveying trough 5 for conveying from left to right. By arranging the first spiral conveying shaft 13, the crop stalks conveyed from the first conveying trough 4 can be conveyed to the discharge port 12 with the help of the first spiral conveying shaft 13, and discharged through the discharge port 12. Not only can a good stalk conveying route be formed in the entire threshing chamber 2, but also during the conveying process, the whole process is carried out on the screen 3, so that when the stalks rotate with the first spiral conveying shaft 13, they will constantly touch the screen 3, so that some grains that have not fallen to the lower part of the threshing chamber 2 in the first conveying trough 4 in time can fall down, thereby improving the threshing effect and avoiding waste.
[0027] Embodiment 2:
[0028] Based on the above embodiments, Figure 2 , 3 As shown in FIG. 4 , a plurality of first shovel plates 14 are arranged around the threshing shaft 8 at a position aligned with the through hole 11; a third shovel plate 29 is arranged around the outer wall of the first spiral conveying shaft at a position aligned with the discharge port 12. By arranging the first shovel plates 14, the stems in the first conveying trough 4 can be pushed into the second conveying trough 5 well, and by arranging the third shovel plates 29, the stems in the second conveying trough 5 can be discharged to the outside of the thresher body 1 through the discharge port 12 well.
[0029] like Figure 5 As shown, the bottom of the threshing chamber 2 is provided with a second spiral conveying shaft 15 for conveying from right to left, and the rear side of the thresher body 1 is provided with a grain outlet 16 connected to the threshing chamber 2 at the lower part near the left end. By providing the second conveying shaft and the grain outlet 16, the separated grains, wheat grains, etc. can be continuously discharged from the grain outlet 16 by rotating the second conveying shaft.
[0030] like Figure 3As shown, a grain discharging pipe 17 is arranged obliquely upward at the rear side of the thresher body 1, the lower end of the grain discharging pipe 17 is connected to the grain discharging port 16, and the upper end is connected to a collecting bucket 18, the side of the collecting bucket 18 is connected to the grain discharging pipe 17, the upper end of the collecting bucket 18 is connected to a suction fan 20 through a suction pipe 19, and the lower end of the collecting bucket 18 is provided with an outlet 21; a second shovel plate 22 is arranged around the outer wall of the second spiral conveying shaft 15 at a position aligned with the grain discharging port 16. With such an arrangement, during the threshing process, processed grains, wheat grains, etc. will fall from the screen 3, and some broken stems or stems and leaves will also fall below the screen 3. When collecting grains and wheat grains, the grains in the threshing chamber 2 are thrown toward the grain outlet pipe 17 by the second shovel plate 22, and fly to the collecting barrel 18 with the help of the grain outlet pipe 17. When entering the collecting barrel 18, with the help of the suction force generated by the exhaust fan 20, the lighter broken stems or leaves will be sucked away through the suction pipe 19, while the heavier grains will fall directly from the outlet 21. A bag or bucket is usually placed below the outlet 21 to catch them.
[0031] Embodiment 3:
[0032] Based on the above embodiments, Figure 1 As shown, an upper baffle 23 is obliquely arranged above the inlet 7, the lower side of the upper baffle 23 is connected to the rear side of the inlet 7 in an up-and-down rotation manner, and a left baffle 24 and a right baffle 25 are respectively arranged on the left and right sides of the upper baffle 23, and the left baffle 24 and the right baffle 25 are respectively connected to the left and right sides of the inlet 7. By arranging the upper baffle 23, the left baffle 24 and the right baffle 25, the surrounding area can be protected and shielded when rice ears, wheat ears, etc. are fed in. On the one hand, the rice ears, etc. can be guided to enter the inlet 7, and on the other hand, during the threshing process, it is inevitable that some grains will splash in the threshing process, so the grains can be bounced back with the help of the upper baffle 23, the left baffle 24 and the right baffle 25. In order to make the volume of the thresher body 1 smaller when it is stored, the left baffle 24 and the right baffle 25 can be installed on the left and right sides of the inlet 7 by means of a slot installation method. When the thresher body 1 is not needed, the left baffle 24 and the right baffle 25 can be disassembled and laid flat, and the upper baffle 23 can be rotated around the inlet 7 to lay flat, so that the volume occupied by the upper baffle 23, the left baffle 24 and the right baffle 25 can be reduced. In addition to being detachable, the left baffle 24 and the right baffle 25 can also be foldable, for example, the left baffle 24 is formed by splicing two symmetrical plates, the joints are connected by hinges, and the upper and lower sides of the left baffle 24 are respectively connected to the upper baffle 23 and the inlet 7 by hinges, so that the upper baffle 23 can be laid flat for storage by folding the left baffle 24.
[0033] The second threshing blade 10 is provided with a cutting edge 26 on one side thereof that meets the rotation direction of the first threshing blade 9. By providing the cutting edge 26, a stem having a long length can be cut.
[0034] A plurality of threshing rods 27 parallel to the threshing shaft 8 are arranged around the threshing shaft 8, and the plurality of threshing rods 27 are connected to the threshing shaft 8 through a connecting plate 28, and a first threshing sheet 9 is arranged on the outside of the threshing rod 27. By arranging the threshing rod 27, the ears of grain can be beaten during the threshing process, and the ears of grain and the screen 3 can be beaten, so that the grains fall off the ears of grain.
