[0001] The present invention relates to the technical field of grain processing equipment, and in particular to a smart digital bulk grain weighing and sampling hopper for a port. Background Art

[0002] At present, many ports use the grab cranes on transport ships to unload materials onto dock equipment, and then transport them to designated locations through dock conveying equipment or trucks. At this time, it is necessary to design a hopper that can realize quantitative feeding to achieve flexible, mobile and continuous quantitative feeding loading and unloading operations.

[0003] The existing Chinese published patent number is: CN104816958A.

[0008] As a further improvement of the present invention: a storage bin is movably embedded near the center of the right side of the hopper body, and drainage plates are fixedly installed on both sides of the interior of the hopper body and near the bottom of the storage bin, and a filtering structure is fixedly embedded inside the hopper body and on the side opposite to the two drainage plates.

[0009] As a further improvement of the present invention: a feed slot is opened at the top center of the filtering structure, a filter element is movably embedded in the right center of the hopper body and located inside the filtering structure, a third rotating element is movably embedded in the left center of the hopper body and located inside the center of the filter element, and a plurality of stirring blades are fixedly sleeved on the outer surface of the third rotating element and close to the inner wall of the filter element.

[0011] As a further improvement of the present invention: slide rails are fixedly installed at both ends of the front bottom center of the hopper body, a first baffle is slidably connected to the bottom of the sampling slot on the opposite side of the two slide rails, a weighing device is fixedly installed at the bottom end of the inner rear side of the hopper body, a discharge pipe is fixedly connected to the rear side of the hopper body and at the top of the rear side of the weighing device, and a second baffle is movably embedded at the top center of the discharge pipe and at the rear side of the hopper body.

[0012] Compared with the prior art, the advantages and positive effects of the present invention are:

[0013] 1. In the embodiment of the present invention, after the bulk material enters the feed port, it passes through the feed pipe installed at the bottom of the feed port and then enters the hopper body. When the bulk material enters the hopper body, the feed baffle controls the flow rate of the bulk material into the hopper body. When the bulk material passes through the feed baffle and enters the hopper body, the staff can turn on the dual-axis motor, so that the dual-axis motor rotates and drives the first rotating member installed on the right side of the dual-axis motor and connected to the inner ring of the bearing to rotate, so that the first rotating member rotates. While rotating, it drives the large gear, middle gear and small gear mounted on its outer surface to rotate synchronously, and the small gear drives the driven gear mounted on the second rotating member meshing with it and movably embedded in the hopper body to rotate synchronously while rotating, so that the driven gear drives the second rotating member to rotate and at the same time drives the rotating fan installed on the right side of the second rotating member and located inside the hopper body to rotate, so that when the bulk grain falls into the hopper body, the deflated shells and other lighter debris inside the bulk grain are blown into the storage bin embedded in the hopper body.

[0014] 2. In the embodiment of the present invention, when the staff wants to increase the flow rate of bulk grain, the first telescopic member installed at the bottom of the feed port and connected to the top of the hopper body can be lowered, so that the first telescopic member drives the feed port to be lowered and drives the feed pipe installed at the bottom of the feed port to be lowered synchronously, thereby making the bottom of the feed pipe press against the feed baffle, so that the feed baffle is matched with the first connecting rod installed at the top thereof and the connecting member movably sleeved on the outer surface of the first connecting rod and installed on the top of the hopper body, so that the feed baffle is flipped, thereby increasing the gap with the bottom of the feed pipe, thereby increasing the flow rate of bulk grain and making the feed port be lowered. When the flow rate of bulk grain increases, the first hinge installed on the feed port can be synchronized with the third connecting rod installed on the second hinge through the first hinge installed on the feed port, and then through the third hinge installed at the bottom of the third connecting rod, the support plate installed at the bottom of the third hinge and movably embedded in the hopper body is pulled to move leftward, so that the support plate drives the dual-axis motor installed on its top to move synchronously while moving leftward, so that the dual-axis motor drives the dual-axis motor installed on the dual-axis motor while moving leftward. The first rotating member on the right side of the output shaft moves synchronously, thereby causing the large gear, medium gear, and small gear sleeved on the outer surface of the first rotating member to move synchronously, causing the medium gear to mesh with the driven gear to increase the speed of the rotary fan, thereby preventing the deflated shells or some lighter debris contained in the bulk grain from being unable to be blown away due to the excessive flow rate of the bulk grain. The bearing installed on the front side of the first rotating member cooperates with the second connecting rod installed on the right side of the bearing outer ring and the first hinge installed on the second connecting rod and connected to the feed baffle, thereby preventing the first rotating member from getting stuck when it is pulled to the left, so that the first rotating member cannot drive the gear sleeved thereon to rotate. According to the setting of the large gear, medium gear, and small gear, the speed of the rotary fan is divided into three gears, thereby making it suitable for bulk grains with different flow rates. When the support plate is pulled outward, it drives the reset spring installed on the right side of the support plate and connected to the left side of the hopper body to be pulled outward synchronously with the second telescopic member. When the staff makes the feed port rise and reset, the support plate can be quickly reset, thereby reducing the time for resetting the speed of the rotary fan.

[0015] 3. In the embodiment of the present invention, when in use, after the bulk grain has passed through the rotating fan to clean the shells and other debris, the bulk grain entering the hopper body is caused to pass through the guide plate installed in the hopper body and the feed slot opened on the top of the filter structure into the filter element embedded in the hopper body. After the bulk grain enters the filter element, it can be rotated by the stirring blade installed on the third rotating member, thereby performing a secondary screening on the bulk grain, so that the bulk grain passes through the filter element and falls into the filter structure, while large debris such as stones contained in the bulk grain remains in the filter element. When the staff pulls out the filter element to clean the debris remaining inside, the dual-axis motor rotates and drives the third rotating member to rotate through the belt installed on the left output shaft thereof, so that the third rotating member drives the stirring blade installed thereon to rotate synchronously while rotating, so that the bulk grain passes through the filter element and the stirring blade and other structures and is cleaned for the second time. The first baffle is pulled out by the slide rail installed at the bottom of the hopper body, so that the bulk grain flows out of the hopper body through the sampling slot provided on the hopper body, and then the bulk grain is sampled. The linkage structure makes it more convenient and quick for the staff to sample, saving time and effort. When the bulk grain falls to the bottom of the hopper body, the bulk grain is weighed by the weighing device at the rear side of the hopper body. After the bulk grain is weighed, the staff can pull out the second baffle to make the bulk grain pass through the discharge pipe installed on the hopper body, so that the bulk grain flows out of the hopper body. When the bulk grain falls to the bottom of the hopper body, the bulk grain is weighed by the weighing device at the rear side of the hopper body. After the bulk grain is weighed, the staff can pull out the second baffle to make the bulk grain pass through the discharge pipe installed on the hopper body, so that the bulk grain flows out of the hopper body.

[0028] During use, after the bulk material enters the feed port 1, it passes through the feed pipe 101 installed at the bottom of the feed port 1 and then enters the hopper body 103. When the bulk material enters the hopper body 103, the flow rate of the bulk material into the hopper body 103 is controlled by the feed baffle 106. When the bulk material passes through the feed baffle 106 and enters the hopper body 103, the staff can turn on the dual-axis motor 117, so that the dual-axis motor 117 rotates and drives the first rotating member 110 installed on the right side of the dual-axis motor 117 and connected to the inner ring of the bearing 109 to rotate, so that the first rotating member 110 rotates and drives the large gear 111, the middle gear 112 and the small gear 113 which are sleeved on the outer surface thereof. 13 rotates synchronously, and the small gear 113 drives the driven gear 115 mounted on the second rotating member 114 meshing with it and movably embedded in the hopper body 103 to rotate synchronously, so that the driven gear 115 drives the second rotating member 114 to rotate and drives the rotating fan 116 installed on the right side of the second rotating member 114 and located inside the hopper body 103 to rotate, so that when the bulk grain falls into the hopper body 103, the deflated shells and other lighter debris in the bulk grain are blown into the storage bin 206 embedded in the hopper body 103, and when the staff wants to increase the flow rate of the bulk grain, they can lower the first telescopic member 102 installed at the bottom of the feed port 1 and connected to the top of the hopper body 103, so that When the first telescopic member 102 drives the feed port 1 to descend, it drives the feed pipe 101 installed at the bottom of the feed port 1 to descend synchronously, so that the bottom of the feed pipe 101 is pressed against the feed baffle 106, so that the feed baffle 106 is matched with the first connecting rod 105 installed on the top thereof and the connecting member 104 movably sleeved on the outer surface of the first connecting rod 105 and installed on the top of the hopper body 103, so that the feed baffle 106 is flipped, and the gap with the bottom of the feed pipe 101 is increased, thereby increasing the flow rate of bulk grain and causing the feed port 1 to descend. When the flow rate of bulk grain increases, it can be synchronized with the first hinge 107 installed on the feed port 1 and the third connecting rod 201 installed on the second hinge 2, and then the feed baffle 106 is turned over by the third connecting rod 201 installed at the bottom of the third connecting rod 201. The third hinge 202 cooperates with the third hinge 202 at the bottom, thereby pulling the support plate 203 installed at the bottom of the third hinge 202 and movably embedded in the hopper body 103 to move leftward, so that the support plate 203 drives the dual-axis motor 117 installed on the top thereof to move synchronously while moving leftward, so that the dual-axis motor 117 drives the first rotating member 110 installed on the right side of the output shaft of the dual-axis motor 117 to move leftward, thereby causing the large gear 111, the middle gear 112, and the small gear 113 sleeved on the outer surface of the first rotating member 110 to move synchronously, so that the middle gear 112 meshes with the driven gear 115, thereby increasing the speed of the rotating fan 116, preventing the deflated shells or some lighter debris contained in the bulk grain from being unable to be blown away due to the excessive flow rate of the bulk grain.The bearing 109 mounted on the front side of the first rotating member 110 cooperates with the second connecting rod 108 mounted on the right side of the outer ring of the bearing 109, and the first hinge 107 mounted on the second connecting rod 108 and connected to the feed baffle 106. This prevents the first rotating member 110 from getting stuck when it is pulled leftward, thereby preventing the first rotating member 110 from driving the gear mounted thereon to rotate. Furthermore, the arrangement of the large gear 111, the middle gear 112, and the small gear 113 allows the rotating fan 116 to rotate in three gears, thereby making it suitable for bulk grains with different flow rates.

[0029] In another embodiment, the first telescopic member 102 may be a hydraulic rod or a telescopic rod, which is not limited here. The preferred structure is a hydraulic rod, and the first rotating member 110 and the second rotating member 114 may be rotating shafts.

[0030] like Figure 1-8 As shown, in one embodiment, a second hinge 2 is fixedly installed at both ends of the left center of the feed port 1, one end of the third connecting rod 201 is movably connected to the center of the two second hinges 2, and the other ends of the two third connecting rods 201 are movably connected to the third hinge 202, and a support plate 203 is fixedly installed at the bottom of the two third hinges 202, and the right outer surface of the support plate 203 is movably embedded in the left side of the hopper body 103, and the bottom of the dual-axis motor 117 is fixed to the top of the support plate 203, and the second telescopic parts 204 are fixedly installed at both ends of the right side of the support plate 203. Both are fixedly installed with return springs 205, and the inner surfaces of the two return springs 205 are movably mounted on the outer surface of the second telescopic part 204. The right sides of the two second telescopic parts 204 and the two return springs 205 are fixed on the left side of the hopper body 103. When the support plate 203 is pulled outward, the return spring 205 installed on the right side of the support plate 203 and connected to the left side of the hopper body 103 and the second telescopic part 204 are pulled outward synchronously. When the staff makes the feed port 1 rise and reset, the support plate 203 can be quickly reset, thereby reducing the time for resetting the speed of the rotating fan 116.

[0031] In another embodiment, the second telescopic member 204 may be a pull rod or a telescopic rod, which is not limited here, and is preferably a telescopic rod.

[0032] like Figure 1-8As shown, in one embodiment, a storage bin 206 is movably embedded near the center of the right side of the hopper body 103, and guide plates 207 are fixedly installed on both sides of the interior of the hopper body 103 and near the bottom of the storage bin 206. A filter structure 208 is fixedly embedded inside the hopper body 103 and on the side opposite to the two guide plates 207. After the bulk grain passes through the rotating fan 116 to clean the shrunken shells and other debris, the bulk material entering the hopper body 103 can pass through the guide plates 207 installed inside the hopper body 103 and enter the filter element 210 embedded in the hopper body 103 through the feed slot 209 opened on the top of the filter structure 208.

[0033] like Figure 1-8 As shown, in one embodiment, a feed slot 209 is provided at the top center of the filter structure 208, a filter element 210 is movably embedded at the right center of the hopper body 103 and located inside the filter structure 208, and a third rotating member 211 is movably embedded at the left center of the hopper body 103 and located inside the center of the filter element 210. A plurality of stirring blades 212 are fixedly sleeved on the outer surface of the third rotating member 211 and close to the inner wall of the filter element 210. After the bulk grain enters the filter element 210, it can be rotated by the stirring blades 212 installed on the third rotating member 211, thereby performing a second screening on the bulk grain, so that the bulk grain passes through the filter element 210 and falls into the filter structure 208, and then large debris such as stones contained in the bulk grain remains in the filter element 210, and then the staff can pull out the filter element 210 to clean the debris remaining inside.

[0034] In another embodiment, the filter element 210 may be a filter screen or a filter sieve plate, which is not limited here, but is preferably a filter sieve plate.

[0035] like Figure 1-8As shown, in one embodiment, a discharge slot 213 is provided at the bottom center of the filtering structure 208, one end of a belt 214 is movably sleeved on the left outer surface of the third rotating member 211, and the other end of the belt 214 is movably sleeved on the outer surface of the left output shaft of the dual-axis motor 117, and a sampling slot 215 is provided at the center of the bottom end of the inner front side of the hopper body 103, so that the dual-axis motor 117 can rotate while the belt 214 sleeved on the left output shaft drives the third rotating member 211 to rotate, so that the third rotating member 211 can drive the stirring device installed thereon while rotating. The blades 212 rotate synchronously, so that after the bulk grain passes through the filter element 210 and the stirring blades 212 and other structures for secondary cleaning, it can flow into the bottom side of the hopper body 103 through the discharge slot 213 opened at the bottom of the filter structure 208. The staff can then pull out the first baffle 217 through the slide rail 216 installed at the bottom of the hopper body 103, so that the bulk grain can flow out of the hopper body 103 through the sampling slot 215 opened on the hopper body 103, and then sample the bulk grain. The linkage structure makes it more convenient and quick for the staff to take samples, saving time and effort.

[0036] like Figure 1-8 As shown, in one embodiment, slide rails 216 are fixedly installed at both ends of the center of the front bottom of the hopper body 103, and a first baffle 217 is slidably connected to the opposite side of the two slide rails 216 and at the bottom of the sampling slot 215. A weighing device 218 is fixedly installed at the bottom end of the inner rear side of the hopper body 103, and a discharge pipe 219 is fixedly connected to the rear side of the hopper body 103 and at the rear top of the weighing device 218. A second baffle 220 is movably embedded at the top center of the discharge pipe 219 and at the rear side of the hopper body 103. When the bulk grain falls into the bottom of the hopper body 103, the bulk grain is weighed by the weighing device 218 at the rear side of the hopper body 103. After the bulk grain is weighed, the staff can pull out the second baffle 220 to allow the bulk grain to pass through the discharge pipe 219 installed on the hopper body 103 and flow out of the hopper body 103.

[0037] Working principle: When in use, after the bulk material enters the feed port 1, it passes through the feed pipe 101 installed at the bottom of the feed port 1 and then enters the hopper body 103. When the bulk material enters the hopper body 103, the feed baffle 106 controls the flow rate of the bulk material into the hopper body 103. When the bulk material passes through the feed baffle 106 and enters the hopper body 103, the staff can turn on the dual-axis motor 117, so that the dual-axis motor 117 rotates and drives the first rotating member 110 installed on the right side of the dual-axis motor 117 and connected to the inner ring of the bearing 109 to rotate, so that the first rotating member 110 rotates and drives the large gear 111 and the middle gear 112 mounted on its outer surface. , the small gear 113 rotates synchronously, and the small gear 113 drives the driven gear 115 mounted on the second rotating member 114 meshing with it and movably embedded in the hopper body 103 to rotate synchronously while rotating, so that the driven gear 115 drives the second rotating member 114 to rotate and at the same time drives the rotating fan 116 installed on the right side of the second rotating member 114 and located inside the hopper body 103 to rotate, so that when the bulk grain falls into the hopper body 103, the deflated shells and other lighter debris inside the bulk grain are blown into the storage bin 206 embedded in the hopper body 103, and when the staff wants to increase the flow rate of the bulk grain, they can make the first telescopic member 102 installed at the bottom of the feed inlet 1 and connected to the top of the hopper body 103 move downward. When the feeding port 1 is lowered, the first telescopic member 102 drives the feeding pipe 101 installed at the bottom of the feeding port 1 to descend synchronously, thereby making the bottom of the feeding pipe 101 press against the feeding baffle 106, so that the feeding baffle 106 cooperates with the connecting member 104 which is movably sleeved on the outer surface of the first connecting rod 105 and installed on the top of the hopper body 103 through the first connecting rod 105 installed on the top thereof, so that the feeding baffle 106 is turned over, thereby increasing the gap with the bottom of the feeding pipe 101, thereby increasing the flow rate of the bulk grain, and making the feeding port 1 descend. When the flow rate of the bulk grain increases, it can be synchronized with the first hinge 107 installed on the feeding port 1 and the third connecting rod 201 installed on the second hinge 2, and then the feeding baffle 106 is turned over by the third connecting rod 20 1 cooperates with the third hinge 202 at the bottom, thereby pulling the support plate 203 installed at the bottom of the third hinge 202 and movably embedded in the hopper body 103 to move leftward, so that the support plate 203 drives the dual-axis motor 117 installed on its top to move synchronously while moving leftward, so that the dual-axis motor 117 drives the first rotating member 110 installed on the right side of the output shaft of the dual-axis motor 117 to move leftward, thereby causing the large gear 111, the middle gear 112, and the small gear 113 sleeved on the outer surface of the first rotating member 110 to move synchronously, so that the middle gear 112 engages with the driven gear 115, thereby increasing the speed of the rotating fan 116, preventing the deflated shells or some lighter debris contained in the bulk grain from being blown away due to the excessive flow rate of the bulk grain.And by cooperating with the bearing 109 installed on the front side of the first rotating member 110, the second connecting rod 108 installed on the right side of the outer ring of the bearing 109, and the first hinge 107 installed on the second connecting rod 108 and connected to the feed baffle 106, the first rotating member 110 can be prevented from getting stuck when it is pulled to the left, so that the first rotating member 110 cannot drive the gear mounted thereon to rotate. According to the setting of the large gear 111, the middle gear 112, and the small gear 113, the speed of the rotating fan 116 is divided into three gears, so that it can be suitable for bulk grain with different flow rates. When the support plate 203 is pulled outward, the return spring 205 installed on the right side of the support plate 203 and connected to the left side of the hopper body 103 is pulled outward synchronously with the second telescopic member 204. When the staff makes the feed port 1 rise and reset, the support plate 203 can be quickly reset, thereby reducing the time for resetting the speed of the rotating fan 116. During use, after the bulk grain passes through the rotating fan 116 to clean the shrunken shells and other debris, the bulk grain entering the hopper body 103 passes through the guide plate 207 installed inside the hopper body 103 and the feed slot 209 opened on the top of the filter structure 208 to enter the filter 210 embedded in the hopper body 103. After entering the filter 210, the bulk grain can pass through the stirring blade 212 installed on the third rotating member 211. The filter 210 is rotated to screen the bulk grains for the second time, so that the bulk grains fall into the filter structure 208 through the filter element 210, and the large debris such as stones contained in the bulk grains remain in the filter element 210. The staff then removes the filter element 210 to clean the debris left inside, and the dual-axis motor 117 rotates while driving the third rotating member 211 to rotate through the belt 214 installed on the left output shaft thereof, so that the third rotating member 211 rotates while driving the third rotating member 211 installed on it. The stirring blades 212 rotate synchronously, so that the bulk grains can pass through the filter element 210 and the stirring blades 212 and then flow into the bottom side of the hopper body 103 through the discharge slot 213 at the bottom of the filter structure 208. The staff can then pull out the first baffle 217 through the slide rail 216 installed at the bottom of the hopper body 103, so that the bulk grains can flow out of the hopper body 103 through the sampling slot 215 on the hopper body 103, thereby sorting the bulk grains. Sampling, and the linkage structure makes it more convenient and quick for the staff to take samples, saving time and effort, so that the bulk grain falls into the bottom of the hopper body 103, and the bulk grain is weighed by the weighing device 218 on the rear side of the hopper body 103. After the bulk grain is weighed, the staff can pull out the second baffle 220 to make the bulk grain pass through the discharge pipe 219 installed on the hopper body 103, so that the bulk grain flows out of the hopper body 103, and the bulk grain falls into the bottom of the hopper body 103.The bulk grain is weighed by the weighing device 218 at the rear side of the hopper body 103. After the bulk grain is weighed, the staff can pull out the second baffle 220 to allow the bulk grain to flow out of the hopper body 103 through the discharge pipe 219 installed on the hopper body 103.
