[0044] A cover plate 3 is mounted on the frame 1 and is located above the roller 2;

[0045] The concave screen 4 is located below the drum 2 and forms two threshing chambers with the cover plate 3. The two drums 2 are respectively located in the two threshing chambers.

[0046] In actual use, the utility model is provided with a detachable threshing component 21 and a separating component 23 on the drum 2. On the one hand, by replacing the threshing component 21 and the separating component 23 on the drum 2, the utility model can be applied to harvesting different crops, thereby achieving the best harvesting effect; on the other hand, if the threshing component 21 and / or the separating component 23 are damaged during grain separation, the damaged threshing component 21 and / or the separating component 23 can be replaced, thereby reducing the maintenance time of the utility model.

[0047] Specifically, the schematic diagram of the threshing element 21 being installed on the first connecting seat 22 is as follows: Figure 8 As shown, a mounting groove is provided on the first connecting seat 22, and the threshing member 21 is placed in the mounting groove. The screw 27 passes through the first connecting seat 22 and the threshing member 21, and is screwed on the screw 27 through the nut 28, so that the threshing member 26 is fixed on the first connecting seat 22; in addition, in this embodiment, the threshing member 21 is a trapezoidal rod tooth.

[0048] Specifically, the schematic diagram of the separation member 23 being installed on the second connection seat 24 is as follows: Fig. 9 As shown, the second connecting seat 24 is provided with an arc-shaped mounting surface 240, and the mounting surface 240 is attached to the drum 2. The separator 23 is arranged on the side surface 241 of the second connecting seat 24 opposite to the mounting surface 240. The separator 23 and the second connecting seat 24 are fixed to the drum 2 by a second screw 29, wherein the second screw can be a hexagonal screw; in addition, in this embodiment, the separator 23 is a trapezoidal plate tooth.

[0049] In addition, it should be noted that although the positions of the feeding section, threshing section, separation section and debris removal section of the drum 2 are not marked in this embodiment, the division of the feeding section, threshing section, separation section and debris removal section of the drum 2 can be known through the positions of the spiral blade 20, the threshing element 21, the separation element 23 and the debris removal plate 25.

[0050] In addition, in the present embodiment, the first connecting seat 22 and the second connecting seat 24 are spirally distributed on the drum 2, so that the threshing element 21 and the separating element 23 are spirally distributed on the drum 2. In this way, in actual use, the spirally distributed threshing element 21 and the separating element 23 can perform efficient threshing and separation work on the grains, which can reduce the loss of grains and make the utility model have broad application prospects.

[0051] In this embodiment, the length of the drum 2 is set between 3m and 4.5m, so as to increase the contact time between the grain and the drum 2, thereby making the grain feeding more uniform and smoother during the operation, and making the threshing and separation of the drum 2 stronger; illustratively, the length of the drum 2 can be 3.75m, 4.2m or 4.25m.

[0052] In addition, Figure 7 In the embodiment, the drum 2 is further provided with a roller 26. In actual use, the drum 2 can be driven to rotate by driving the roller 26 to rotate.

[0053] Reference Figure 4 In this embodiment, the cover plate 3 includes an arc-shaped first cover plate 30 and an arc-shaped second cover plate 31, combined with Figure 1 The first cover plate 30 and the second cover plate 31 are mounted on the frame 1 through the cover plate fixing bolt 35 and the cover plate fixing seat 36. More specifically, the structure and Figure 3 , three fixing rods 11 are arranged on the frame 1, a first cover plate 30 and an arc-shaped second cover plate 31 are fixed on the three fixing rods 11, the first cover plate 30 is located above one roller 2, the second cover plate 31 is located above another roller 2, and a feeding port 34 is provided at one end of the first cover plate 30 and the second cover plate 31 near the feeding section of the roller 2. In actual use, when the spiral blades 20 on the feeding section of the roller 2 rotate, the grains are transferred from the feeding port 34 to the de-feeding cavity formed by the cover plate 3 and the concave screen 4.

[0054] In addition, refer to Figure 4 In this embodiment, the inner side surface of the first cover plate 30 and the inner side surface of the second cover plate 31 are provided with a plurality of guide plates 32 along the length direction of the cover plate 3. The inclination angle of the guide plates 32 gradually increases along the direction of crop transportation. In actual use, the guide plates 32 with a smaller inclination angle are conducive to grain transportation, and the guide plates with a larger inclination angle can have a better promoting effect on the axial movement of the grain. Exemplarily, the angle of the guide plates 32 in the cover plate 3 gradually changes from 53° to 70°.

[0055] In addition, in this embodiment, a baffle plate 33 is provided between the first cover plate 30 and the second cover plate 31 .

[0056] Reference Figure 2 and Figure 3In this embodiment, the cover plate 3 covers the threshing section, separation section and impurity removal section of the drum 2. A feeding assembly 5 is provided at the feeding section of the two drums 2 on the frame 1. The feeding assembly 5 includes a feeding port, a feeding cavity and a discharging port. The discharging port is connected with the feeding port. The spiral blade 20 is in the feeding cavity. When rotating, the crops in the feeding cavity are transported from the discharging port and the feeding port 34 to the threshing cavity in sequence.

[0057] Specifically, in Figure 3 In the figure, the feed chamber is formed by connecting a first inclined plate 50, a second inclined plate 51, a first arc baffle 52, a second arc baffle 53 and a connecting piece 54. The first inclined plate 50 is connected to the second inclined plate 51, and the inclination angle of the first inclined plate 50 is smaller than the inclination angle of the second inclined plate 51. The upper part of the left side edge of the first inclined plate 51 is connected to the outer side edge of the first arc baffle 52, the upper part of the right side edge of the first inclined plate 51 is connected to the outer side edge of the second arc baffle 53, and the connecting piece 54 is connected to the inner side edge of the first arc baffle 52 and the inner side edge of the second arc baffle 53.

[0058] Reference Figure 3 and Figure 4 The concave screen 4 includes a first concave screen 40 and a second concave screen 47 which are arranged in sequence along the direction of conveying the crop, wherein the second concave screen can be fixed to the frame 1 by screws. Figure 3 In the figure, two vertical plates 41 are connected to the first concave plate screen 40, each vertical plate 41 is provided with a support rod 42, both ends of each support rod 42 are respectively connected with a screw 43, the screw 43 is screwed to the support seat 45, each support seat 45 is provided with a travel hole 46, and the support rod 42 passes through the travel hole 46.

[0059] In actual use, when it is necessary to adjust the gap between the first concave screen 40 and the drum 2, the position of the screw 43 on the support seat 45 can be adjusted first, for example, the screw 43 is raised or lowered, and after the adjustment is completed, the screw 43 is locked on the support seat 45 by the locking nut 44, so as to adjust the height of the first concave screen 40, so that the utility model can thresh and separate crops of different sizes, and has good compatibility. For example, when it is necessary to harvest small-weight crops such as wheat and rice, the gap between the first concave screen 40 and the drum 2 can be adjusted to between 30mm-35mm, and when it is necessary to harvest large-weight crops such as corn and soybeans, the gap between the first concave screen 40 and the drum 2 can be adjusted to between 35mm-40mm.

[0060] In actual use, two sections of concave screens are set, so that when the grains are in the threshing section of the drum 2, the grains can be transported to the separation section of the drum 2 through the action of the first concave screen 40, the threshing element 21 and the guide plate 32. At the separation section of the drum 2, by setting the screening spacing of the second concave screen 47, the grains can fall off the second concave screen 47. On the one hand, it can prevent the threshing element 21 from repeatedly hitting the grains to damage the grains. On the other hand, it can also prevent the grains from entering the subsequent cleaning mechanism along with the redundant materials generated in the separation process, which is convenient for the later cleaning work.

[0061] Reference Fig.10 In this embodiment, the utility model further includes a driving device 6, which is connected to the end of the roller shaft 26 of the two rollers 2 away from the spiral blade 20, and is used to drive the two rollers 2 to move toward each other. The driving device 6 includes a gear box base 63, on which two gear boxes 62 and a hydraulic motor 60 are installed. The output shaft of the hydraulic motor 60 is connected to the gear box 62 through a coupling 61, and is used to drive the output shafts of the two gear boxes 62 to rotate, and the speed regulation range is large. In addition, a box body partition 64 is also provided on the gear box base 63, and the box body partition 64 can be used to isolate the stripping chamber and the gear box 62.

[0062] In actual use, the two rollers 2 are driven to rotate by the hydraulic motor 60, so that the stepless speed change of the two rollers 2 can be realized, and the rotation speed of the two rollers 2 can be flexibly adjusted according to actual needs.

[0063] In addition, in this embodiment, a sensor for detecting the rotation speed of the rollers 26 of the two rollers 2 may be provided on the frame 1. In a certain implementation manner, the rotation speed of the rollers 26 of the rollers 2 may be negatively feedback controlled by the output signal of the sensor.

[0064] In actual use, the working process of the utility model can be divided into four processes: feeding, threshing, separation and impurity removal, as follows:

[0065] Feeding process: corn grains are fed through the feeding assembly 5, and the grains are transported into the stripping chamber to perform spiral motion under the high-speed rotation of the spiral blades 20 of the two rollers 2;

[0066] Threshing process: The grains move backward and begin to contact the threshing member 21. After being hit and squeezed by the threshing member 21 and the adjustable first concave screen 40, the grains begin to fall off. Driven by the two rollers, the grains continue to move backward and the grains are further fallen off. A small number of grains that are not completely threshed in small pieces can be transported to the threshing section of the roller 2 through the existing re-threshing conveying device for threshing again.

[0067] Separation process: Due to the high-speed rotation of the two drums 2, some of the grains produced during the threshing process cannot pass through the second concave screen 47 and fall into the cleaning system by their own weight in a short time. The impurities produced during the threshing process are stirred and hit by the separator 23 during the separation process. Since the masses of the grain impurities are different, the centrifugal forces generated by the rotational motion are different. The grain impurities will be separated and layered under the action of the centrifugal force. The hitting action of the separator 2 further threshes some of the unthreshed grains to ensure that they can fall into the cleaning screen smoothly.

[0068] Impurity removal process: Under the rotation of the drum 2, the light impurities in the stripping cavity gradually move to the impurity removal plate 25, and are finally smoothly discharged from the drum threshing space under the action of the impurity removal plate 25, completing the entire double longitudinal axial flow threshing process.

[0069] In summary, compared with the prior art, the present invention has the following beneficial effects:

[0070] 1. In actual use, the threshing element 21 and the separating element 23 on the drum 2 can be replaced to make the utility model suitable for harvesting different crops, thereby achieving the best harvesting effect;

[0071] Second: The whole structure is designed as an integrated unit, which can be installed as a whole on the threshing and separation equipment during actual installation. It is easy to install and is also conducive to later debugging and maintenance;

[0072] Third: By providing a detachable threshing component 21 and a separating component 23 on the drum 2, if the threshing component 21 and / or the separating component 23 are damaged during grain separation, the damaged threshing component 21 and / or the separating component 23 can be replaced, thereby reducing the maintenance time of the utility model;

[0073] Fourth: By spirally distributing the threshing element 21 and the separating element 23 on the drum 2, the grains can be efficiently threshed and separated, which can reduce the grain loss and has a broad application prospect;

[0074] Fifth: By setting the length of the drum 2 between 3m and 4.5m, the residence time of the grain in the drum 2 can be increased, so that during the operation, the grain is fed more evenly and smoothly, and the threshing and separation performance of the drum 2 is stronger;

[0075] Six: By replacing different concave screens 4, it can adapt to the harvesting of different agricultural crops, reducing the time loss of farmers and grain harvesting machine owners, and enhancing the applicability of the machine; and because the machine can harvest different crops, the machine can harvest crops continuously in a year, increasing the harvesting time of the machine;

[0076] In addition, the gap between the first concave screen 40 and the drum 2 can be adjusted manually, so that when the electric control adjustment mechanism of the machine fails, the gap between the first concave screen 40 and the drum 2 can be adjusted promptly and accurately;

[0077] Seven: The hydraulic motor 60 drives the output ends of the two gear boxes 62 to rotate, and then drives the rollers 26 of the two rollers 2 to rotate, so that the rotation speed of the rollers 2 can be adjusted steplessly, and the adjustment range is large.

[0078] The above is based on the enlightenment of this utility model. Through the above description, relevant staff can make various changes and modifications without deviating from the technical idea of ​​this utility model. The technical scope of this utility model is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
