Description

Technical Field

[0001] The invention relates to the technical field of particle storage, in particular to a multi-point feeding distribution device for a granary. Background Art

[0002] At present, the grain storage in my country adopts the method of loading and unloading grain from the top center of the storage bin through a conveying system. Under the action of free fall, the grain naturally accumulates from bottom to top. Since grain particles have different particle sizes and different natural modification angles formed by grain during the stacking process, grain particles with larger particle sizes will roll to the outer edge of the storage bin along the formed modification angle, while grain particles with smaller particle sizes will accumulate in the middle area of ​​the storage bin. Grain discharge mostly adopts the bottom center discharge form or the bottom multiple discharge form. The current problems with the above-mentioned grain storage and feeding forms are as follows: Large-sized grain materials on the upper part of the grain roll down to the inner and outer edges of the grain storage bin, while small-sized grain materials accumulate in the middle area of ​​the bin. When the bin is ventilated, aerated and pest-killing, the grain in the small-sized material area will directly affect the preservation of the materials due to the different gaps between large and small-sized grains, and is likely to cause the grain to heat up, become moldy and infested with insects. Most grain storage bins have one or more discharge ports in the center of the bin bottom. If the particle size of the materials in the bin is not evenly distributed, the quality of subsequent grain storage will be directly affected when the grain is taken out of the bin for production and processing. Summary of the invention

[0003] The purpose of the present invention is to provide a multi-point feeding distribution device for a granary, aiming to solve the problem that the granary feeding distribution device in the general technology easily leads to uneven distribution of grain.

[0004] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: the multi-point feeding distribution device of the granary includes: a granary top cover, a distribution mechanism, a distribution mechanism and a driving mechanism; the distribution mechanism has a feeding cylinder rotatably connected to the granary top cover, a plurality of discharge holes are opened at the bottom of the feeding cylinder, a plurality of discharge troughs opposite to the discharge holes are fixedly installed on the bottom wall of the feeding cylinder, the discharge troughs are inclined from top to bottom and from the middle to the edge, and the particles enter the feeding cylinder and are discharged through the discharge holes and the discharge troughs; the distribution mechanism cover is arranged on the outside of the discharge trough of the distribution mechanism, The interior of the material distribution mechanism is provided with a plurality of evenly distributed side discharge ports, the discharge end of the discharge trough is located in the middle of the side discharge port, a baffle is formed between two adjacent side discharge ports, and a central discharge port is provided at the bottom of the material distribution mechanism; the driving mechanism is installed on the feed barrel and the top cover of the granary, and is used to drive the feed barrel to rotate, so that a part of the particles discharged from the discharge trough passes through the side discharge ports and falls into the relative edge of the bottom of the granary, and another part of the particles discharged from the discharge trough falls from the central discharge port into the relative center of the bottom of the granary through the blocking of the baffle.

[0005] The beneficial effect is as follows: by setting a feed barrel rotatably connected to the top cover of the granary, a discharge trough is set at the bottom of the feed barrel, and a driving mechanism is set to drive the feed barrel and the discharge trough connected thereto to rotate, and a dividing mechanism is set to cover the discharge trough, and a side discharge port and a central discharge port are opened on the dividing mechanism, particles enter the barrel and are discharged through the discharge trough, so that a part of the particles are discharged through multiple side discharge ports and fall into the relative edges of the bottom of the granary, and the other part of the particles are blocked by the dividing mechanism and discharged from the central discharge port and fall into the relative center of the bottom of the granary, thereby achieving the purpose of multi-point uniform distribution.

[0006] A further technical solution of the present invention is that a reinforcement rod is fixedly installed at the bottom of the material distribution mechanism, and the reinforcement rod extends upward to the interior of the feed barrel. The reinforcement rod is rotatably connected to the feed barrel through a sealed bearing, and an auger for assisting material discharge is fixedly installed on the outer surface of the reinforcement rod located in the feed barrel part.

[0007] The beneficial effect is that since the feed barrel is rotating, the particles inside the barrel rotate with the feed barrel, so that the auger rotates relative to the feed barrel and the particles inside it, so as to facilitate the discharge of the particles inside the feed barrel and avoid blockage that affects the feeding mechanism.

[0008] A further technical solution of the present invention is that a sealing cover plate is installed on the discharge chute, and the sealing cover plate is used to prevent particles from spilling out from the top of the discharge chute when the discharge chute rotates at a high speed.

[0009] The beneficial effect is that the setting of the sealing cover plate can prevent the particles from sliding out and spilling from the top of the discharge chute due to the large centrifugal force generated when the discharge chute rotates at a high speed.

[0010] A further technical solution of the present invention is that the material dispensing mechanism comprises a shell, the shell comprises a vertical section, a transition section and an inclined section, the vertical section and the inclined section are both annular, and the vertical section is fixedly connected to the granary top cover.

[0011] A further technical solution of the present invention is that the cross section of the transition section is arc-shaped, the side feed opening is opened inside the transition section, and the interval between two adjacent side feed openings is a baffle.

[0012] A further technical solution of the present invention is that a first baffle is fixedly installed on both sides of the side discharge port, the first baffle is fixedly connected to the baffle, a second baffle is fixedly installed on the bottom of the side discharge port, the second baffle is fixedly installed at the edge of the upper surface of the inclined section, and the first baffle and the second baffle are both used to prevent particles blocked by the baffle from falling from the side discharge port.

[0013] The beneficial effect is that it can prevent the particles blocked by part of the baffle from leaking out through the side discharge port when sliding down to the center of the inclined section, resulting in uneven material distribution.

[0014] A further technical solution of the present invention is that two third baffles are installed on the inner wall of the baffle, and a middle discharge trough is opened at the inclined section near the transition section. The area between the first baffle and the third baffle is opposite to the position of the middle discharge trough, and the particles falling between the first baffle and the third baffle fall directly from the middle discharge trough.

[0015] The beneficial effect is that a part of the particles blocked by the baffle can fall through the middle discharge chute, thereby filling the space between the particles at the relative edges and the particles at the relative center of the bottom of the granary, so as to further improve the uniformity of the distribution.

[0016] A further technical solution of the present invention is that a plurality of circumferentially distributed connecting strips are fixedly installed on the inner circumferential wall of the inclined section, and a fixing plate for installing the reinforcement rod is fixedly installed at one end of the plurality of connecting strips, and the fixing plate is located at the center of the inclined section.

[0017] A further technical solution of the present invention is that the driving mechanism includes a connecting shaft rotatably mounted inside a fixed plate, a driving pulley is fixedly mounted on the outer surface of the connecting shaft, a driven pulley is fixedly mounted on the outer surface of the feeding barrel, and the driving pulley and the driven pulley are connected by a belt.

[0031] Embodiment 1: In general technology, grain is stored by loading and unloading grain from the top center of the storage bin through a conveying system. Under the action of free fall, the grain naturally accumulates from bottom to top, causing grain particles with larger particle sizes to roll to the outer edge of the storage bin along the formed modified angle, while grain particles with smaller particle sizes will accumulate in the middle area of ​​the storage bin, resulting in uneven distribution of grain particles.

[0032] Based on the above problems, this embodiment Figure 1As shown, a multi-point feeding device for grain silo includes a grain silo top cover 1, a feeding mechanism 2 is rotatably installed inside the grain silo top cover 1, a feeding mechanism 3 is fixedly installed on the bottom wall of the grain silo top cover 1, and a driving mechanism 4 for driving the feeding mechanism 2 is fixedly installed on the upper surface of the grain silo top cover 1.

The number of the side feeding ports 31 is multiple, and the multiple side feeding ports 31 are evenly distributed so that a gap for feeding grains is formed between two adjacent side feeding ports 31. A baffle 32 is provided to block the particles, a central discharge port 33 is provided at the bottom of the distribution mechanism 3, and the driving mechanism 4 drives the distribution mechanism 2 to rotate. The distribution mechanism 2 evenly discharges the introduced particles, a part of the particles are discharged through the side discharge port 31 to fall into the relative edge of the bottom of the granary, and the other part of the particles fall into the relative center of the bottom of the granary from the central discharge port 33 after being blocked by the baffle 32. Moreover, the particles discharged by the distribution mechanism 2 can be dispersed under the blocking of the baffle 32, so that the particles can be evenly distributed inside the granary.

[0033] like Figure 2-Figure 5 As shown, the material distribution mechanism 2 includes a feed barrel 21 rotatably mounted inside the granary top cover 1 through a first connecting bearing 22, the upper and lower ends of the feed barrel 21 both extend out of a portion of the granary top cover 1, a plurality of discharge holes 211 are provided at the bottom of the feed barrel 21, a feeding trough 25 is fixedly mounted on the top of the feed barrel 21, and the feeding trough 25 is trumpet-shaped to facilitate the user to introduce the granular matter, a plurality of discharge troughs 23 are fixedly mounted on the bottom wall of the feed barrel 21, the plurality of discharge troughs 23 are distributed in a circle, and the discharge troughs 23 are inclined from top to bottom and from the middle to the edge, the discharge troughs 23 correspond to the positions of the discharge holes 211, the granular matter entering the feed barrel 21 is discharged to the discharge trough 23 through the discharge hole 211, and the discharge trough 23 discharges the granular matter to the distributing mechanism 3 for distributing.

[0034] The top end of the first connecting bearing 22 extends to a part of the outside of the granary top cover 1, and a fixing plate 24 is fixedly installed on the extended part of the top of the first connecting bearing 22. The fixing plate 24 is fixedly connected to the granary top cover 1 through a first mounting bolt 241. The fixing plate 24 is used to install and reinforce the entire cloth mechanism 2, and a second connecting bearing 242 for installing the driving mechanism 4 is rotatably installed inside the fixing plate 24.

[0035] like Figure 2 and Figure 7As shown, the driving mechanism 4 includes a connecting shaft 41 fixedly mounted inside the second connecting bearing 242, a driving pulley 42 is fixedly mounted on the outer surface of the connecting shaft 41, a driven pulley 43 is fixedly mounted on the outer surface of the feeding drum 21, the driving pulley 42 and the driven pulley 43 are connected by a belt 44, a reduction motor 45 for driving the connecting shaft 41 is fixedly mounted on the top, the reduction motor 45 drives the connecting shaft 41 to rotate so as to drive the feeding drum 21 through the transmission of the pulley and the belt 44, thereby driving the entire cloth mechanism 2 to rotate and cloth.

[0036] A plurality of connecting blocks 451 are fixedly installed on the outer surface of the reduction motor 45 , and fixing rods 452 are fixedly installed on the outer surfaces of the plurality of connecting blocks 451 . The bottoms of the plurality of fixing rods 452 are fixedly connected to the fixing plate 24 , and the reduction motor 45 is installed and fixed by the fixing rods 452 .

[0037] like Figure 2 and Figure 6 As shown, the dispensing mechanism 3 includes a shell 30, and the shell 30 includes a vertical section 301, a transition section 302 and an inclined section 303. The vertical section 301 and the inclined section 303 are both annular, and a plurality of connecting plates 304 are fixedly installed on the top of the outer surface of the vertical section 301. The connecting plates 304 are fixedly connected to the granary top cover 1 through the second mounting bolts 305. The cross-section of the transition section 302 is arc-shaped, and the side discharge port 31 is opened inside the transition section 302. The remaining part of the transition section 302 is a baffle 32, and the central circular hole of the inclined section 303 is the central discharge port 33.

[0038] A plurality of circumferentially distributed connecting strips 306 are fixedly installed on the inner circumferential wall of the inclined section 303, and a fixing plate 307 is fixedly installed at one end of the plurality of connecting strips 306. The fixing plate 307 is located at the center of the inclined section 303, and a reinforcing rod 308 is fixedly installed on the fixing plate 307. The reinforcing rod 308 is rotatably installed at the bottom of the feed barrel 21 through a sealed bearing 3081, and the reinforcing rod 308 extends upward to the inside of the feed barrel 21, and the height of the reinforcing rod 308 is less than the height of the feed barrel 21. An auger 309 is installed on the part of the reinforcing rod 308 located inside the feed barrel 21, and the driving mechanism 4 drives the feed barrel 21 to rotate, so that the particles inside the feed barrel 21 rotate with the feed barrel 21, so that the auger 309 rotates relative to the feed barrel 21 and the particles inside it, so as to facilitate the discharge of the particles inside the feed barrel 21 and avoid blockage that affects the feeding of the cloth mechanism 2.

[0039] A first baffle 311 is fixedly installed on both sides of the side discharge port 31, and the first baffle 311 is fixedly connected to the baffle plate 32. A second baffle 312 is fixedly installed on the bottom of the side discharge port 31, and the second baffle 312 is fixedly installed at the edge of the upper surface of the inclined section 303, thereby preventing particles blocked by part of the baffle plate 32 from leaking out through the side discharge port 31 when sliding down to the center of the inclined section 303, so that the distributing mechanism 3 can distribute the materials relatively evenly.

[0040] During use, the material distributing mechanism 2, the material dividing mechanism 3 and the driving mechanism 4 are first connected and fixed to the granary top cover 1, and then the feeding cylinder 21 of the material distributing mechanism 2 is driven by the reduction motor 45 of the driving mechanism 4 (the speed of the reduction motor 45 can be adjusted according to actual needs), and finally the material to be stored is transported to the feeding trough 25 for feeding by means of a high-lift particle feeding pump or a conveyor belt until the particle storage is completed.

[0041] In this specific embodiment, a plurality of discharge troughs 23 are arranged at the bottom of the feed barrel 21, and a driving mechanism 4 is arranged to drive the feed barrel 21, and a dividing mechanism 3 is arranged, and a plurality of evenly distributed side discharge ports 31 are opened at the discharge port position of the dividing mechanism 3 relative to the discharge trough 23, so that baffles 32 are formed at the intervals of the side discharge ports 31. The driving mechanism 4 drives the discharge trough 23 to rotate so that a part of the particles can fall into the relative edge of the bottom of the granary through the side discharge ports, and the other part of the particles are blocked by the baffle 32 and slide to the center of the dividing mechanism 3 to fall into the relative center of the bottom of the granary, so that the particles can fall into the granary evenly through multiple points, and the two parts of the particles are a mixture of large and small particles, which avoids the problem of uneven mixing of large and small particles when the particles are accumulated, and achieves the purpose of uniform distribution at multiple points.

[0042] Example 2: In the structure of Example 1, all the particles blocked by the baffle 32 are discharged through the central discharge chute 33 and fall into the relative center of the bottom of the granary, resulting in excessive accumulation of particles in the middle of the granary.

[0043] Based on the above problems, this embodiment Fig. 9 As shown, the difference from the first embodiment is that: a third baffle 321 is set in the middle of the inner wall of the baffle 32 near the two sides, a middle discharge trough 34 is opened in the inclined section 303 near the transition section 302, the area between the first baffle 311 and the third baffle 321 is opposite to the middle discharge trough 34, and during the feeding process of the feeding mechanism 2, the particles located between the first baffle 311 and the third baffle 321 fall directly from the middle discharge trough 34.

[0044] Compared with Example 1, the advantage of this embodiment is that a portion of the particles blocked by the baffle 32 can fall through the middle discharge chute 34, thereby filling the space between the particles at the relative edges and the particles at the relative center of the bottom of the granary, and can also make the particles blocked by the baffle 32 more dispersed, thereby further improving the uniformity of the distribution of the material by the distribution mechanism 3.

[0045] Example 3: In the structure of Example 1-2, the discharge chute 23 is an upper opening structure, but as the rotation speed increases, the particles will detach from the upper opening, thereby causing the amount in the middle to increase, making it difficult to control the amount distribution ratio between the side and the middle, and the batching speed of the low-speed batching is low.

[0046] Based on the above problems, this embodiment Fig.10 As shown, a sealing cover 231 is provided on the discharge chute 23, so that a relatively closed space with both ends transparent is formed between the discharge chute 23 and the sealing cover 231 for the particles to pass through, thereby preventing the particles from generating a large centrifugal force and sliding out from the top of the discharge chute 23 and spilling when the discharge chute 23 rotates at a high speed.

[0047] Compared with embodiments 1-2, the advantage of this embodiment is that it is convenient for the user to drive the discharge chute 23 to rotate at high speed without worrying about particles spilling from the top of the discharge chute 23, thereby increasing the discharge speed of the particles and thus improving the overall working efficiency of the device.

[0048] The above-mentioned embodiments of the present invention do not constitute a limitation on the protection scope of the present invention. The basic concept of the present invention is to set a driving mechanism 4 on the feed barrel 21 of the material distribution mechanism 2 and the granary top cover 1, and set a discharge trough 23 at the bottom of the feed barrel 21, and set a distribution mechanism 3 to cover the discharge trough 23, and set a side discharge port 31 and a central discharge port 33 on the distribution mechanism 3. The particles enter the barrel 21 and are discharged through the discharge trough 23, so that part of the particles are discharged through the side discharge port 31 and fall into the relative edge of the bottom of the granary, and the other part of the particles are blocked by the distribution mechanism 3 and discharged from the central discharge port 33 and fall into the relative center of the bottom of the granary. The distribution of the side discharge port 31 and the central discharge port 33 can make the particles fall into the bottom of the granary at multiple points, thereby realizing multi-point uniform distribution. Any modification, equivalent substitution and improvement made within the spirit and principle of the present invention should be included in the protection scope of the claims of the present invention.
