[0061] like Figures 1 to 6As shown, the adjustable rotary blade grain distribution device 100 proposed by the present invention includes a load-bearing rotating mechanism 1, a grain guiding mechanism 2, a grain distribution rotary blade mechanism 3, and an adjustable belt retractable mechanism 4. The load-bearing rotating mechanism 1 includes an annular guide rail, a roller 102, an annular load-bearing plate 101, a support seat 103, and a connecting plate 104. The annular guide rail is used to be installed on the top of the silo. The roller 102 is slidably connected to the annular guide rail so that the roller 102 can make a circular motion along the annular track. The annular load-bearing plate 101 is fixedly connected to the roller 102 so that the annular load-bearing plate 101 and the roller 102 move together. The support seat 103 is located on the central axis of the annular load-bearing plate 101, and its lower part is connected to the lower part of the annular load-bearing plate 101 through the connecting plate 104; the grain guiding mechanism 2 includes a grain guiding column 201, and the grain guiding column 201 has a feed port located at its upper part, a discharge port located at its lower part, and a grain transport channel formed inside to connect the feed port and the discharge port; the grain distribution rotary blade mechanism 3 includes a slide rail 30 2. Slide plate 3043 and rotary blade grain distributor 304. One end of the slide rail 302 is connected to the inner edge of the annular load-bearing plate 101, and the other end thereof is connected to the outer edge of the support seat 103. The slide plate 3043 is slidably connected to the slide rail 302. The rotary blade grain distributor 304 is installed on the slide plate 3043 to disperse the grain entering the rotary blade grain distributor 304 to different areas. The adjustable belt retractable mechanism 4 includes a multi-stage belt, and the multi-stage belts can move closer to or away from each other. The head end of the multi-stage belt is rotatably connected to the lower part of the grain guide column 201 corresponding to the discharge port, and the end thereof is rotatably connected to the upper part of the rotary blade grain distributor 304 to drive the slide plate 3043 to move along the slide rail 302. The grain flowing out of the grain outlet of the grain guide column 201 is transported to the rotary blade grain distributor 304 through the multi-stage belt.

[0062] The technical solution of the present invention is to transport the grain to the center of the top of the circular silo, drop it into the feed port of the grain guide column 201, pass through the grain transport channel inside the grain guide column 201, and fall onto the multi-stage belt from the discharge port. The grain is then transported to the rotary blade grain distributor 304 by the multi-stage belt. The rotary blade grain distributor 304 scatters the grain to different areas. At this time, the multi-stage belts can be extended and retracted, so that the rotary blade grain distributor 304 can move back and forth along the track direction of the slide rail 302 and move radially along the annular load-bearing plate 101; at the same time, the roller 102 moves along the annular guide rail to drive the load-bearing rotating mechanism 1 to make a circular motion, so that the rotary blade grain distributor 304 can rotate around the axial direction of the annular load-bearing plate 101. The rotational movement of the load-bearing rotating mechanism 1 and the reciprocating retractable movement of the adjustable belt telescopic mechanism 4 ensure that the grain distribution rotary blade mechanism 3 can distribute grain regularly in the round silo, from the center rotation grain distribution to the outer wall rotation grain distribution, and then from the outer wall rotation grain distribution to the center rotation grain distribution. Through this cyclic reciprocating operation, dynamic grain distribution in the round silo is achieved, ensuring full coverage of the grain landing points, solving the automatic grading phenomenon that exists when distributing grain in a shallow round silo, improving the uniformity of the gaps in the stacked grain pile, improving the air permeability of the grain, and protecting the safety of grain storage.

[0063] like Figure 2 As shown, it can be understood that the driving of the roller 102 can be achieved by setting a motor at the position of the annular load-bearing plate 101 corresponding to the roller 102, and by directly or indirectly connecting the output shaft of the motor to the central axis of the roller 102, so that the roller 102 can move along the track of the annular track.

[0064] In one embodiment, the grain distribution rotary vane mechanism 3 is provided with a plurality of slide rails 302 equidistantly arranged along the radial direction of the annular bearing plate 101 .

[0065] It can be understood that the multiple grain distribution rotary blade mechanisms 3 arranged can handle the uniform distribution of a large amount of grain, especially in large circular silos, which can avoid excessive operating load of a single grain distribution rotary blade mechanism 3 and improve the grain storage efficiency. Each rotary blade grain distributor 304 is on the radius line of the annular load-bearing plate 101 and maintains the same distance from each other. Such a layout ensures the uniform distribution of the rotary blade grain distributor 304 on the entire circumference, thereby increasing the uniformity and coverage of the grain distribution, ensuring that the grain in the entire circular silo can be well distributed, and promoting the uniform distribution of grain in the silo. Specifically, in the present embodiment, three grain distribution rotary blade mechanisms 3 are provided, and three are used as examples for illustration below.

[0066] like Figure 4As shown, it should be noted that, in this embodiment, an outer circular bearing plate 301 and an inner ring rotating block 303 are also provided. One side of the outer circular bearing plate 301 is connected to the slide rail 302, and the other side is convexly formed with a convex block that matches the groove on the inner edge of the annular bearing plate 101, thereby improving the connection strength between the slide rail 302 and the annular bearing plate 101. The inner edge of the inner ring rotating block 303 is fixedly connected to the support seat 103, and can be connected to multiple sliders along the radial direction of its outer edge, thereby improving the convenience of connection between the slide rail 302 and the support seat 103.

[0067] like Figure 3 As shown, in one embodiment, the grain guiding column 201 is provided with a plurality of discharge ports, and the plurality of discharge ports are equidistantly arranged along the radial direction of the grain guiding column 201. The grain guiding mechanism 2 also includes a plurality of grain guiding partition plates 202, which are arranged at intervals in the grain guiding column 201 to divide the grain transport channel into a plurality of independent channels, and the upper end of each independent channel is connected to the feed port, and the lower end thereof is connected to each discharge port one by one.

[0068] It is understandable that the multiple discharge ports at the bottom of the grain guide column 201 are evenly distributed along the radial direction of the grain guide column 201, so that the grain can be evenly distributed to different areas of the silo from multiple different positions at the same time, reducing the possibility of local accumulation and increasing the uniformity of grain distribution. The grain can be accurately divided into three equal parts when entering the feed port and passing through the grain transport channel through multiple grain guide partitions 202. The grains of each equal part flow out from their respective discharge ports and enter the rotary blade grain distributor 304 through multi-stage belts, which can improve the uniformity of grain distribution.

[0069] In one embodiment, the grain guiding column 201 further includes a grain guiding center column 203 , which is located at the center of the grain guiding column 201 and connected to the plurality of grain guiding partition plates 202 .

[0070] It is understandable that the grain guiding center column 203 can enhance the overall structural stability of the grain guiding column 201 , especially when the grain guiding partition plate 202 is subjected to greater grain pressure, the center column can provide additional support and reduce the risk of structural deformation.

[0071] It should be noted that in this embodiment, the end of the grain guiding center column 203 close to the feed port is configured to be cone-shaped, which can guide the flow of grain inside the grain guiding column 201, especially when the grain enters from the feed port, the center column can play a diversion role, ensuring that the grain enters each independent channel evenly, thereby promoting the uniform distribution of grain in the silo.

[0072] In one embodiment, the grain guiding column 201 further includes a grain guiding plate 204 located at the discharge port, with an upper end thereof connected to the grain guiding column 201 and a lower end thereof rotatably connected to the head end of the multi-stage belt.

[0073] It can be understood that: the grain guide plate 204 is arranged at the discharge port of the grain guide column 201, and is used to directly transfer the grain from the discharge port to the multi-stage belt. The existence of the grain guide plate 204 can ensure the smooth transition of the grain from the grain guide column 201 to the multi-stage belt, and reduce the loss and waste of grain during the conversion process. The upper end of the grain guide plate 204 is connected to the grain guide column 201 to ensure the stability of the connection. The lower end is connected to the head end of the multi-stage belt by rotation, so the angle between the grain guide plate 204 and the head end of the multi-stage belt can be adjusted according to the actual working conditions to improve the grain transportation efficiency.

[0074] It should be noted that the above two implementations can be used in combination, and their effects are not described in detail here.

[0075] like Figure 5 As shown, in one embodiment, the slide plate 3043 has a through hole, and the rotary blade grain distributor 304 includes a rotary driving member 3046 and an impeller 3041. The rotary driving member 3046 is located above the through hole and connected to the slide plate 3043; the impeller 3041 is located below the through hole and is in driving connection with the driving member, so that the grain transported from the multi-stage belt to the slide plate 3043 falls into the impeller 3041 through the through hole.

[0076] It is understandable that the rotary drive member 3046 can be a motor, and its output end can be connected to the impeller 3041 through the vertical coupling 3045 to ensure the stable rotation of the impeller 3041. In this way, the rotary drive member 3046 is placed on the slide 3043 to prevent the rotary drive member 3046 from being impacted by the grain. At the same time, the impeller 3041 is located below the slide 3043, and the grain will not be scattered to the surrounding mechanical parts, and the grain dispersion trajectory can be maintained, which is convenient for the staff to design the movement trajectory of the grain. At the same time, it also protects the surrounding mechanical parts and prolongs the service life of the device.

[0077] In one embodiment, the rotary blade grain distributor 304 includes a semi-cylindrical baffle 3044 mounted on the upper surface of the slide plate 3043, and one side thereof having an opening is arranged corresponding to the end of the multi-stage belt;

[0078] It is understandable that the semi-cylindrical baffle 3044 is installed on the upper surface of the slide plate 3043, and its shape is semi-cylindrical and has a certain height to prevent the grain from scattering or overflowing on the slide plate 3043. Through the guidance of the semi-cylindrical baffle 3044, the grain can enter the rotary blade grain distributor 304 faster through the through hole, thereby improving the efficiency and accuracy of the entire grain distribution. The design of the opening ensures that the grain can be smoothly transferred from the multi-stage belt to the slide plate 3043 without causing waste or confusion during the transportation process.

[0079] It should be noted that the semi-cylindrical baffle 3044 can also serve as a supporting structure for the rotating drive member 3046, without the need for additional mechanical structures for support, thereby reducing the complexity of the overall device.

[0080] In one embodiment, the rotary blade grain distributor 304 includes a cover plate 3042 which is sleeved on the upper portion of the impeller 3041 to close the upper portion of the impeller 3041 so that the grain flows out from the lower portion of the impeller 3041 .

[0081] It is understandable that the cover plate 3042 is designed to be set on the upper part of the impeller 3041 to close the upper space of the impeller 3041. Under the rotation of the impeller 3041, the grain can only flow out from the lower part of the impeller 3041 instead of flying around, preventing the grain from rebounding upward or overflowing horizontally, so that the grain can only be distributed in a preset direction and range, allowing the operator to adjust the rotation speed of the impeller 3041 and the position of the slide plate 3043 to accurately control the distribution density and range of the grain to perform a uniform grain distribution operation.

[0082] It should be noted that the above two implementations can be used in combination, and their effects are not described in detail here.

[0083] like Figure 6 As shown, in one embodiment, the multi-stage belt includes a first belt 401, a second belt 402, and a third belt 403, and the adjustable belt retractable mechanism 4 also includes a first transverse plate 404, a second transverse plate 405, and a mounting seat 406. The first end of the first transverse plate 404 is connected to the lower part of the food guide column 201 corresponding to the discharge port, and the first transverse plate 404 is configured to place the first belt 401; the upper side of the second transverse plate 405 is slidably connected to the lower side of the first transverse plate 404, and the second transverse plate 405 is configured to place the second belt 402; the upper side of the mounting seat 406 is slidably connected to the lower side of the second transverse plate 405, and the mounting seat 406 is configured to place the third belt 403.

[0084] It is understandable that a multi-stage transmission system is formed by arranging the first belt 401, the second belt 402, and the third belt 403 in sequence. Each belt stage transmits grain from one position to the next position, and a longer distance and a complex transmission path can be covered by multi-stage transmission. The head end of the first transverse plate 404 is connected to the lower part of the grain guide column 201 corresponding to the discharge port, so that the grain coming out of the discharge port can enter the second belt 402 under the transportation of the first belt 401, and the second transverse plate 405 and the first transverse plate 404 are connected by sliding to adjust the relative position to adapt to different transmission distances. The grain on the second belt 402 then falls to the third belt 403, and the mounting seat 406 is connected by sliding to the lower side of the second transverse plate 405, and also provides a mounting position for the third belt 403. By adjusting the position of the mounting seat 406 on the second transverse plate 405, the mounting seat 406 and the second transverse plate 405 are connected by sliding to adjust the relative position to adapt to different transmission distances. Through multiple adjustments, the transportation distance of multiple belts can be extended or reduced to meet the requirements of grain distribution.

[0085] It should be noted that the grain on the first belt 401 can fall directly into the rotary blade grain distributor 304 without passing through the second belt 402, the third belt 403, and the second belt 402 and the third belt 403, and its specific use can be adjusted according to actual grain distribution needs.

[0086] In one embodiment, the adjustable belt retractable mechanism 4 also includes: a first gear 407, a first rack 408, a second gear 407, a second rack 408, and two retractable driving components 4094; the first gear 407 is installed on the lower side of the first horizontal plate 404; the first rack 408 is installed on the upper side of the second horizontal plate 405 and meshes with the first gear 407; the second gear 407 is installed on the lower side of the second horizontal plate 405; the second rack 408 is installed on the lower side of the mounting seat 406 and meshes with the second gear 407; one retractable driving component 4094 is installed on the lower side of the first horizontal plate 404 and is transmission connected to the first gear 407, and the other retractable driving component 4094 is installed on the lower side of the second horizontal plate 405 and is transmission connected to the second gear 407.

[0087] It can be understood that by introducing a first gear 407, a first rack 408, a second gear 407, a second rack 408 and two telescopic driving components 4094, the relative position relationship between the first horizontal plate 404, the second horizontal plate 405 and the mounting seat 406 is adjusted through a telescopic driving component 4094.

[0088] As described in detail below, when the telescopic driving member 4094 installed on the lower side of the first transverse plate 404 is started, it drives the first gear 407 to rotate. Since the first gear 407 is meshed with the first rack 408 installed on the upper side of the second transverse plate 405, the linear motion of the first rack 408 will occur, thereby pushing the second transverse plate 405 to move relative to the first transverse plate 404. When the telescopic driving member 4094 installed on the lower side of the second transverse plate 405 drives the second gear 407 to rotate. Since the second gear 407 is meshed with the second rack 408 installed on the lower side of the mounting seat 406, this rotation will be converted into the linear motion of the second rack 408, thereby affecting the relative position between the second transverse plate 405 and the mounting seat 406.

[0089] like Figure 7 As shown, in one embodiment, the telescopic driving member 4094 includes a worm wheel 4091, a worm 4092, and a telescopic driving member 4094. The worm wheel 4091 is coaxially rotatable with the first gear 407 or the second gear 407; the worm 4092 is meshed with the worm wheel 4091; and the telescopic driving member 4094 is coaxially rotatable with the worm 4092.

[0090] It is understood that the worm wheel 4091 is a gear 407 with helical teeth, which is used in conjunction with the worm 4092. In this design, the worm wheel 4091 is coaxially arranged with the first gear 407 or the second gear 407, which means that the worm wheel 4091 and one of the gears 407 are fixed on the same shaft and they will rotate together. The purpose of this is to convert the output of the worm wheel 4091 and the worm 4092 into the rotational movement of the gear 407, thereby affecting the position change of the rack 408. The worm 4092 is a shaft with a threaded shape, and its thread meshes with the helical teeth of the worm wheel 4091. Since the contact between the worm 4092 and the worm wheel 4091 is a point contact, this structure can provide a very high reduction ratio, that is, the worm 4092 rotates multiple times to make the worm wheel 4091 rotate one circle, which enables the system to provide a large torque and achieve precise control. In addition, the worm gear 4091 and worm 4092 mechanism usually has a self-locking property, that is, it is difficult to reverse drive the worm 4092, which helps to maintain the stability of the system and prevent displacement under uncontrolled conditions. The telescopic drive member 4094 is arranged to rotate coaxially with the worm 4092, which means that it is fixed on the same axis as the worm 4092. The telescopic drive member 4094 can use a motor, which is connected to the worm 4092 through a transverse coupling 4093 to generate initial rotational power. When the telescopic drive member 4094 rotates, it will drive the worm 4092 to rotate, and then transmit power to the gear 407 through the worm gear 4091, and finally realize the linear movement of the rack 408.

[0091] In summary, this set of telescopic driving components 4094 provides high precision, high torque and self-locking capability through the worm gear 4091 and worm 4092 mechanism, and is suitable for the relative position relationship between the first cross plate 404 , the second cross plate 405 , and the mounting seat 406 .

[0092] like Figure 8 As shown, in one embodiment, the adjustable rotary blade grain distribution device 100 further includes two inclined components, one inclined component is installed between the head end of the multi-stage belt and the lower part of the grain guide column 201 corresponding to the discharge port, and the other inclined component is installed between the end of the multi-stage belt and the rotary blade grain distributor 304, and the inclined components include an inclined upper block 504, an end cover 503, a connecting shaft 501, and an inclined lower block 502. The inclined upper block 504 is installed to the lower part of the grain guide column 201 corresponding to the discharge port or the end of the multi-stage belt; the end cover 503 is connected to the inclined upper block 504, which has a rotating cavity; the connecting shaft 501 is inserted into the rotating cavity and is rotatably connected to the end cover 503; the inclined lower block 502 is connected to the connecting shaft 501.

[0093] It is understandable that, since the connecting shaft 501 and the end cover 503 can be rotatably connected, the inclined upper block 504 and the inclined lower block 502 can change the angle between the two around the axis of the connecting shaft 501. One of the inclined upper blocks 504 is fixedly connected to the discharge port of the grain guide column 201, and the corresponding inclined lower block 502 is fixedly connected to the head end of the multi-stage belt, ensuring that the grain can be smoothly transported from the grain guide column 201 to multiple belts, and another inclined upper block 504 is fixedly connected to the end of the multi-stage belt, and the corresponding inclined lower block 502 is fixedly connected to the rotary blade grain distributor 304. Ensure that the grain can be smoothly transported from the multi-stage belt to the rotary blade grain distributor 304.

[0094] Through the combination of the above components, the inclined component can adjust the angle, which is convenient for the adjustable telescopic mechanism of the rotary blade grain distributor 304 to frequently change the angle changes brought about by the relative positions of multiple belts during the continuous movement process, thereby improving the overall operation smoothness of the device.

[0095] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
