Description

Technical Field

[0001] The utility model belongs to the technical field of weighing bins, and in particular relates to a weighing, conveying and discharging device. Background Art

[0002] Conventional auger conveying devices do not have the height of the weighing bin. If the discharge port of the weighing bin is set on the inner side of the weighing bin, when the material height in the bin is high, the material will be transported from the bottom first, and the material above the discharge port will accumulate on the top. When the vibration is large, it will fall down together with the horizontally conveyed material flow, causing the discharge fluctuation and affecting the accuracy. Utility Model Content

[0003] The utility model aims to provide a weighing conveying and discharging device, which is used to solve the technical problem of low discharging accuracy of the existing auger conveying device.

[0004] In order to solve the above technical problems, the utility model adopts the following technical scheme, a weighing conveying and discharging device, which is characterized by comprising:

[0005] A weighing bin, wherein the weighing bin is tilted;

[0006] A discharge bin is arranged at the discharge end of the weighing bin, and a discharge port is arranged on the discharge bin;

[0007] The feeding auger is arranged through the weighing bin and the discharging bin.

[0008] In order to better control the accuracy of discharging, the auger extends to the outside of the weighing bin, i.e., the discharging bin, and the discharging port is set below the extended side of the auger, avoiding the influence of the discharging port being set on the upper material inside the weighing bin. The utility model sets a hopper beyond the hopper at the discharging end of the weighing bin, extends the auger out of the weighing bin into the discharging bin, and sets the discharging port at the discharging bin at the end of the auger extension, further improving the accuracy of discharging control.

[0009] In order to solve the technical problem of the design of the discharge port position, the utility model adopts the following technical solution, wherein the discharge port is arranged at the bottom or side of the discharge bin to meet the needs of different scenarios.

[0010] In order to solve the technical problem that the material at the discharge port causes impact on the downstream equipment, the utility model adopts the following technical solution, and the discharge port includes:

[0011] A first discharge port is arranged on the discharge bin, and the first discharge port is vertically arranged between the feeding auger;

[0012] The second discharge port is arranged below the first discharge port, and the second discharge port is inclined outward relative to the first discharge port. The discharge port adopts the above structure, which conforms to the special process arrangement of ranch equipment and is more convenient and reasonable. The utility model designs the discharge port into an inclined structure, which can avoid the impact of materials on the conveyor belt below and reduce the impact and flying of materials.

[0013] In order to solve the technical problem that the material temporarily stored in the silo is arched, causing the material to be discharged in a mass or pile during the conveying process of the auger, the utility model adopts the following technical solution: a dispersing component is provided on the conveying auger in the discharge silo. The material passes through the dispersing component at the discharge end, so that the output material is in a loose state, avoiding the material from being discharged in a mass, and greatly improving the discharge accuracy of the equipment. The dispersing component installed at the tail of the discharge port can avoid the material from being discharged in a mass, so that the material is in a loose state when discharged, which is conducive to the control of the discharge accuracy and the real-time measurement of the weight of the material in the silo.

[0014] In order to further improve the technical problem of discharge accuracy, the utility model adopts the following technical solution: a breaking component is arranged on the feeding screw at the discharge end of the weighing bin. The breaking component can also be arranged in front of the discharge port, so that the material is broken up before discharge, which is conducive to accurate control of the material. If the material is broken up above the discharge port, the agglomerated material at this time will be discharged regardless of whether it is broken up or not, which has little effect on the actual accuracy control.

[0015] In order to solve the problem of how to realize the breaking up assembly, the utility model adopts the following technical solution: the breaking up assembly includes breaking up pieces evenly distributed on the auger shaft of the feeding auger; the breaking up pieces are in the shape of plates, rods or angle steels.

[0016] In order to solve the technical problem of the power source of the feeding auger, the utility model adopts the following technical solution: a driving component is arranged on the discharge bin, and the driving component is connected to the feeding auger.

[0017] In order to further solve the technical problem of the power source of the feeding auger, the utility model adopts the following technical solution: a transmission assembly is arranged on the discharge bin, and the input end of the transmission assembly is connected to the driving assembly; the output end of the transmission assembly is connected to the input end of the feeding auger.

[0018] In order to solve the technical problem of how to realize the feeding auger, the utility model adopts the following technical solution: the feeding auger includes a hollow shaft, and shaft heads are respectively arranged at both ends of the hollow shaft, and the shaft heads are correspondingly supported on bearings arranged on the weighing bin and the discharging bin.

[0019] In order to solve the technical problem that the failure of the feeding auger cannot be detected, the utility model adopts the following technical solution: a detection alarm component is arranged on the shaft head. If there is a chain break, a chain is off, and the operating speed does not meet the requirements, real-time alarm monitoring can be performed. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The present invention will be further described below in conjunction with the accompanying drawings and specific implementations.

[0038] Example 1

[0039] like Figure 1-5 As shown, the weighing, conveying and discharging device 10 includes a bin body 400 and a conveying auger 500 .

[0040] The warehouse body 400 is installed on the frame and is used for temporary storage of materials. The warehouse body 400 includes a weighing warehouse 410 and a discharge warehouse 420 .

[0041] The weighing bin 410 is tilted. The discharging bin 420 is installed at the discharging end of the weighing bin 410 .

[0042] The frame includes a base 100 and a bracket 300. The base 100 is used to support the entire warehouse body; the base 1 is assembled / welded by profiles / sheet metal, and is mainly used to install the weighing component 200 and support the warehouse body 400.

[0043] The bracket 300 is installed at an angle, and the base 100 is installed at the four corners of the bracket 300. The bracket 300 is used to install the warehouse body 400, so that the warehouse body 400 can maintain a certain tilt angle, ensure the process installation arrangement, and have strong applicability. The bracket 300 is assembled / welded into a frame as a whole by profiles / sheet metal, and is mainly used to connect and fix the warehouse body 400.

[0044] The weighing assembly 200 is installed on the silo body and is used to weigh the materials in the silo. Specifically, multiple groups of weighing assemblies 200 are installed between the base 100 and the bracket 300. The weighing assembly 200 is preferably a high-precision weighing module. The weighing assembly 200 is composed of a weighing sensor, a junction box and a matching display instrument. The weighing sensor is connected to the junction box and the instrument. The instrument (or central control system) is used to install and display the discharge amount each time. The change in the weight of the material in the silo can be displayed in real time and displayed through the instrument / external display. The sensor of the weighing assembly 200 adopts a high-precision dynamic weighing module, which makes the overall measurement accuracy higher and compensates for the accuracy interference caused by the dynamic transportation of materials inside the equipment.

[0045] The discharge bin 420 is provided with a discharge port 421. In one embodiment, the discharge port 421 is provided at the bottom of the discharge bin 420. In one embodiment, the discharge port 421 is provided at the side of the discharge bin 420.

[0046] In one embodiment, the discharge port 421 includes a first discharge port 4211 and a second discharge port 4212. The first discharge port 4211 is installed on the discharge bin 420, and is vertically arranged between the first discharge port 4211 and the feeding auger 500. The second discharge port 4212 is located below the first discharge port, and the second discharge port 4212 is tilted outward relative to the first discharge port 4211. The discharge port adopts the above structure, which conforms to the special process arrangement of ranch equipment and is more convenient and reasonable. The utility model designs the discharge port into an inclined structure, which can avoid the impact of materials on the conveyor belt below and reduce the impact and flying of materials.

[0047] The feeding auger 500 is arranged in the weighing bin 410 and the discharging bin 420. Specifically, the feeding auger 500 includes an auger shaft 501, which is a hollow shaft structure. Shaft heads 502 are respectively arranged at both ends of the auger shaft, and the shaft heads 502 are correspondingly supported on bearings arranged on the weighing bin and the discharging bin. A spiral blade 502 is arranged on the hollow shaft 501 to transport the material to the discharging port.

[0048] In one embodiment, a detection alarm component 540 is provided on the shaft head 502. If there is a chain break, a chain drop, or the running speed does not meet the requirements, real-time alarm monitoring can be performed.

[0049] In one embodiment, in order to solve the problem that the material agglomeration at the discharge port affects the discharge accuracy, the utility model designs a breaking component 530 on the auger shaft at the discharge end of the feed auger 500 in the discharge bin 420 .

[0050] The breaking assembly 530 can be designed in the discharge bin 420. The breaking assembly can be arranged above the discharge port, and the material-beating plate increases the downward impact force of the material, and the cooperation with the inclined material-discharging device can reduce the impact on the bottom.

[0051] The breaking component 530 can also be designed inside the discharge end of the weighing bin 410. The breaking component can also be set in front of the discharge port, so that the material is broken up before discharging, which is conducive to accurate control of the material. If it is broken up above the discharge port, the agglomerated material at this time will be discharged regardless of whether it is broken up or not, which actually has little effect on the precision control.

[0052] Specifically, the dispersing assembly 530 includes dispersing pieces 531 evenly distributed on the auger shaft of the feed auger. The dispersing pieces 531 are evenly distributed in the circumferential direction of the auger and are arranged in a staggered manner. Figure 6a , Figure 6b , Figure 6c As shown, the breaking piece 531 can be in the shape of a plate, a rod, or an angle steel. The breaking plate and the auger shaft can be connected by assembly or welding.

[0053] The material passing through the discharging component at the end of the discharging port can make the output material in a loose state, avoid the material from being discharged in a lump, and greatly improve the discharging accuracy of the equipment. The discharging component installed at the tail of the discharging port can avoid the material from being discharged in a lump, making the material in a loose state when it is discharged, which is conducive to the control of the discharging accuracy and the real-time measurement of the weight of the material in the bin.

[0054] The utility model arranges an asymmetric breaking up component at the tail of the material conveyor, that is, the tail of the feeding auger, to break up the material during the discharging process of the material, thereby ensuring that the material is in a loose state during the output process, thereby changing the discharging form of the material, making the material evenly scattered to the next process, which is beneficial to the weighing and metering of the overall equipment, the control accuracy of the whole machine is higher, and the discharging error is smaller.

[0055] The discharge port includes an opening below the feeding auger and a first discharge port below the opening. The first discharge port is not inclined and may include a small vertically arranged portion. Since the material has an initial velocity horizontal to the auger under the push of the auger, if the first discharge port is directly set to a vertically downward structure, the material will frequently hit the side wall of the extension part, resulting in unsmooth material discharge. In addition, the second discharge port is set to an inclined structure, which can also avoid the impact of the material on the conveyor belt below and reduce the impact and flying of the material.

[0056] In one embodiment, a drive assembly 600 is disposed on the discharge bin 530, and the drive assembly 600 can be directly connected to the feed auger 500. The drive assembly 600 includes a reduction motor, a reduction motor adjustment seat, and an adjustment screw rod.

[0057] In one embodiment, a transmission assembly 700 is provided on the discharge bin 530, and the input end of the transmission assembly 700 is connected to the driving assembly 600; the output end of the transmission assembly 700 is connected to the input end of the feeding auger 500. The transmission assembly can be an existing transmission structure such as a chain transmission structure, a belt transmission structure or a gear transmission structure to meet the needs of different scenarios. The chain transmission form adopted in this embodiment is composed of a driven sprocket, a chain, and a driving sprocket.

[0058] The silo is used to store materials temporarily and is elevated by a bracket to facilitate cleaning at the bottom of the silo. A feeding auger (single or multiple) is installed inside the silo. The feeding auger is driven by a reducer through direct connection, belt drive or chain drive. The rotation of the auger drives the spiral blades to transport materials. Multiple groups of weighing sensors are installed between the silo and the bracket. The weighing sensors are connected to a junction box and an instrument. The output of each material is set and displayed through the instrument (or central control system).

[0059] The utility model is applied to the rapid and accurate batching of special roughage (corn meal / flakes, cotton seeds, distiller's grains, etc.) in ranch / animal husbandry, which improves the batching efficiency of ranch, reduces labor costs, and reduces the waste of roughage. It can also be applied to other industries including quantitative weighing and conveying of materials.
