Abstract
Description
Technical Field
[0001] This utility model belongs to the field of crop threshing technology, specifically relating to a cyclone separator, a cyclone separator component, and a threshing machine. Background Technology
[0002] In crop threshing equipment, the cyclone separator plays a crucial role in separating grain particles from impurities (broken straw, husks, soil, and dust, etc.). The effectiveness of the cyclone separator largely determines the cleanliness of the grain particles. There is a considerable amount of existing technical literature on cyclone separators for agricultural applications. (See attached...) Figure 1 This is a common cyclone separator structure used in crop threshing equipment. It includes a hollow cylinder body, which consists of a conical upper cylinder 11, a cylindrical middle cylinder 12, and an inverted conical lower cylinder 13. The two ends of the middle cylinder 12 are connected to the upper cylinder 11 and the lower cylinder 13, respectively. The top of the upper cylinder 11 is provided with a waste outlet 111, which is used to connect with a negative pressure pipeline. The bottom of the lower cylinder 13 is provided with a discharge outlet 131 (i.e., the cleaned grain particles are discharged from the discharge outlet 131). The lower part of the middle cylinder is equipped with a feed pipe 2, which is connected to the middle cylinder 12 along the tangent direction. The middle cylinder is provided with a feed inlet connected to the feed pipe 2. After the threshing chamber of the threshing equipment threshes the crops, the grain particles and mixed impurities (broken straw, husks, soil, and dust, etc.) are thrown into the cylinder 1 through the feed pipe 2 by the high-speed rotating lifting plate. Since the feed pipe 2 is arranged along the tangential direction of the middle cylinder 12, the grain particles and impurities will move spirally along the inner wall of the middle cylinder 12. After the grain particles and impurities enter the cylinder 1, the negative pressure suction provided by the negative pressure pipe connected to the impurity outlet 111 and their own gravity cause the heavier grain particles (and soil) to gradually fall into the lower cylinder 13 and be discharged through the discharge port 131, while the lighter impurities (such as straw, husks, and dust, etc.) gradually float up and enter the upper cylinder 11, and finally enter the negative pressure pipe through the impurity outlet 111 and be discharged, thereby achieving the separation of grain particles and relatively light impurities.
[0003] Combination Figure 2 (Including 2a and 2b) and Figure 3 To reduce the amount of grain being sucked away by negative pressure, a separation cone 3 is installed on the upper cylinder 11 or the middle cylinder 12 (where, for example...). Figure 2 a and Figure 2 b and Figure 3The separating cone shown in the example (the existing technology has various structural forms of the separating cone 3) When some grain particles move upward to the separating cone 3, the separating cone 3 can block the grain particles, thereby reducing the number of grain particles sucked into the negative pressure pipe by negative pressure, thus reducing the waste and loss of grain particles. In the specific implementation process, when some grain particles move to the top of the separating cone, some grain particles will also fall due to the obstruction of the inner wall of the upper cylinder 11. Therefore, in order to facilitate the downward sliding of grain particles, the upper surface of the separating cone is an inclined surface sloping downward.
[0004] However, because the lifting plates of the threshing equipment rotate synchronously with the auger shaft, and the speed of the lifting plates is as high as 2000-3000 r / min, the force exerted by the lifting plates on the grain particles (and mixed impurities) is relatively large. The initial velocity of the grain particles and impurities entering the intermediate cylinder 12 of the cylinder 1 is relatively fast and the centrifugal force is relatively large. Under the combined action of negative pressure suction, some grain particles will continue to move upward along the cylinder 1 and enter the upper cylinder 11 and finally be discharged from the impurity outlet, which leads to poor separation effect of grain particles and impurities and grain waste. Utility Model Content
[0005] This invention addresses the problem of grain waste caused by existing cyclone separators easily discharging grain particles from the impurity outlet. It provides a cyclone separator, a cyclone separation component, and a threshing machine that can reduce the amount of grain particles discharged from the impurity outlet of the cyclone separator, thereby improving the separation effect between grain particles and impurities and reducing grain waste.

[0017] This invention, by increasing the height of the cylinder, can also prevent grain particles from being discharged from the impurity outlet at the top of the cylinder, thereby improving the separation effect of grain particles and impurities and reducing grain particle waste.
[0018] Meanwhile, this utility model can be improved on existing threshing equipment (or threshing machines), and has the advantages of simple modification and low modification cost. Attached Figure Description

[0021] The present invention will be further described below with reference to the embodiments. The described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, other embodiments obtained by those skilled in the art without creative effort are all within the protection scope of the present invention.
[0022] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model; the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance; furthermore, unless otherwise explicitly specified and limited, the terms "installed," "connected," and "joined" should be interpreted broadly, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.
[0023] Combined with appendix Figure 1 To be continued Figure 18 The cyclone separator of this utility model includes a hollow cylinder 1. The cylinder 1 has a feed inlet 121 for communication with a feed pipe. A baffle is installed on the inner wall of the cylinder 1 above the feed inlet 121 to reduce the upward movement height of the grain particles. Alternatively, the cylinder 1 above the feed inlet 121 may be a heightened cylinder. The feed pipe is connected to the auger chamber of the thresher. The lifting plates inside the auger chamber, rotating at high speed, throw the grain particles and impurities into the feed pipe 2. Through the conveying action of the feed pipe 2, the grain particles enter the interior of the cylinder 1 through the feed inlet 121. How the cyclone separator achieves feeding is clear and understandable to those skilled in the art, and will not be elaborated further here.
[0024] This invention installs a baffle on the inner wall of the cylinder above the feed inlet. The baffle reduces the upward speed of the material (including grain particles and impurities entering the cylinder through the feed inlet), thereby reducing the height of the grain particles inside the cylinder and preventing them from being discharged from the impurity outlet at the top of the cylinder. This improves the separation effect between grain particles and impurities and reduces grain waste.
[0025] This invention, by increasing the height of the cylinder, can also prevent grain particles from being discharged from the impurity outlet at the top of the cylinder, thereby improving the separation effect of grain particles and impurities and reducing grain particle waste.
[0026] In the prior art, the height of the middle cylinder 12 of the cylinder 1 is generally three times the radius. As a preferred embodiment of this utility model, the height of the middle cylinder 12 is 3.5-4.5 times the radius, while the position of the feed inlet on the middle cylinder 12 remains unchanged. Therefore, the middle cylinder 12 above the feed inlet can be heightened.
[0027] In practice, since the lifting plates and the auger shaft of the threshing equipment rotate coaxially, reducing the auger shaft speed, while lowering the lifting plate speed and thus the force exerted on the material, ultimately reducing the material's entry speed into the cylinder 1, can cause blockages and jamming within the auger chamber. Furthermore, in some threshing equipment, the speed of the exhaust fan providing negative pressure suction into the cylinder is also related to the auger shaft speed. This can lead to insufficient negative pressure suction provided by the exhaust fan to the cylinder 1, significantly increasing the amount of impurities in the grain particles discharged from the outlet, ultimately resulting in poor separation of grain particles from impurities. Considering all these factors, reducing the lifting plate rotation speed to decrease the material's entry speed into the cylinder is not advisable.
[0028] Therefore, by setting a baffle inside the cylinder and / or raising the cylinder, this invention can minimize the amount of grain particles discharged from the impurity outlet at the top of the cylinder, improve the separation effect of grain particles and impurities, and ultimately reduce grain waste. Furthermore, this invention can be easily modified from existing threshing equipment (or threshers), offering advantages such as simple modification and low modification cost.
[0029] In some embodiments, a separating cone 3 is provided inside the cylinder 1, and there is a gap between the baffle and the separating cone 3. The function of the separating cone 3 has been described in the background section of this application and will not be repeated here. The gap between the baffle and the separating cone 3 forms a channel for the upward movement of the material.
[0030] In some embodiments, the baffle is located below the separating cone 3, and / or the baffle is located above the separating cone 3. That is, in some embodiments, one baffle is provided inside the cylinder 1; in some embodiments, two or more baffles are provided inside the cylinder 1. When there are two or more baffles, each baffle is separate and independent, such that some baffles are located above the separating cone, while some baffles are located below the separating cone.
[0031] In some embodiments, the cylinder 1 includes an upper cylinder 11, a middle cylinder 12, and a lower cylinder 13 connected sequentially from top to bottom, with the feed inlet 121 located on the middle cylinder 12; the baffle is installed inside the middle cylinder 12, and / or the baffle is installed inside the upper cylinder 11. As mentioned above, the number of baffles is not specifically limited in this invention. Therefore, when the number of baffles is two or more, some baffles are installed on the middle cylinder 12, and some baffles are installed on the upper cylinder 11.
[0032] The impurity outlet 111 is located at the top of the cylinder 1 (i.e., the impurity outlet 111 is located at the top of the upper cylinder 11). The impurity outlet 111 is used to connect with the negative pressure pipe, which provides negative pressure suction to the cylinder 1. Impurities are discharged from the impurity outlet 111 and then enter the negative pressure pipe, and are then discharged through the negative pressure pipe. The discharge outlet 131 is located at the bottom of the cylinder 1 (i.e., the discharge outlet 131 is located at the bottom of the lower cylinder 13). Relatively heavy grain particles and soil particles are discharged from the discharge outlet 131.
[0033] In the specific implementation process, the separation cone 3 on the existing threshing equipment is installed at the discharge port 111 near the cylinder 1. Therefore, as a preferred embodiment of this utility model, in order to reduce the cost of modification, the baffle is installed on the inner wall of the middle cylinder 12.
[0034] In some embodiments, the baffle is one or a combination of a trumpet-shaped baffle cylinder 4, a wear-resistant buffer layer 7, or a particle blocking element 8; the opening size at the upper end of the baffle cylinder 4 is smaller than the opening size at the lower end of the baffle cylinder 4, and the baffle cylinder 4 has a through hole 41 in the middle. The trumpet-shaped baffle cylinder installed on the inner wall of the cylinder can prevent the grain particles from continuing to spiral upward along the inner wall of the cylinder, while reducing the movement speed of the grain particles, thereby reducing the height of the grain particles moving upward; at the same time, it can guide the material to continue to spiral upward gradually along the trumpet-shaped baffle cylinder 4 and be discharged from the through hole 41, avoiding the material (especially relatively light impurities) from being blocked and obstructed by the baffle cylinder 4 and unable to continue to move upward.
[0035] In some embodiments, a cylindrical baffle ring 5 is installed on the top of the baffle cylinder 4. That is, a baffle ring 5 is installed at the top of the through hole 41 of the baffle cylinder 4. The baffle ring 5 can further increase the obstruction effect on the grain particles, limit the movement height of the grain particles in the cylinder 1, and ultimately reduce the discharge of grain particles from the discharge port 111 at the top of the cylinder, thereby reducing grain waste.
[0036] In some embodiments, the top of the baffle cylinder 4 is connected to a funnel-shaped guide cylinder 6. The upper end of the guide cylinder 6 is larger than the lower end. The upper end of the guide cylinder 6 is connected to the inner wall of the cylinder body 1, and the lower end of the guide cylinder 6 is connected to the top of the baffle cylinder 4. In specific implementation, under the blocking effect of the baffle cylinder 4, virtually no grain particles will be discharged upward from the through hole 41 in the middle of the baffle cylinder 4. Even if a small amount of grain particles enter the upper area of the baffle cylinder, the grain particles move to the highest position under their own kinetic energy and then begin to fall. Then, they slide downward with the guidance of the guide cylinder 6, thereby preventing the grain particles from accumulating in the angle between the baffle cylinder 4 and the cylinder body 1.
[0037] In some embodiments, the baffle is a wear-resistant buffer layer 7 arranged on the inner wall of the cylinder 1. The wear-resistant buffer layer 7 is arranged in a ring along the inner wall of the cylinder to buffer the grain particles entering from the feed inlet 121, thereby reducing the kinetic energy of the grain particles and ultimately reducing the height of the grain particles moving upward, preventing the grain particles from being discharged from the discharge outlet at the top of the cylinder.
[0038] In some embodiments, the baffle portion is a plurality of blocking particles 8 arranged on the inner wall of the cylinder 1. The outer surface of the blocking particles 8 is smooth, and the smooth outer surface can prevent impurities from getting entangled on the blocking particles 8.
[0039] In a preferred embodiment of this invention, the blocking particles 8 are made of stainless steel. In some embodiments, each blocking particle 8 is welded to the inner wall of the cylinder. In some embodiments, the blocking particles 8 are pre-installed on a mounting plate, which is then installed on the inner wall of the cylinder 1.
[0040] Preferably, in order to prevent impurities from becoming entangled on the blocking particles 8, the blocking particles 8 are spherical, hemispherical, conical, or cylindrical.
[0041] This utility model also provides a cyclone separator component, which includes a negative pressure pipe connected to a cyclone separator cylinder. The cyclone separator cylinder is the aforementioned cyclone separator cylinder. The negative pressure pipe is used to provide negative pressure suction to the cyclone separator cylinder and to discharge impurities discharged from the impurity outlet 111. Those skilled in the art will understand this, and it will not be described in detail here.
