Description

Technical Field

[0001] The utility model relates to the technical field of accessories for rice processing equipment, and specifically to a feeding mechanism with a metering function. Background Technique

[0002] When performing rice processing operations, such as processing paddy into rice, or using rice as raw material for other processing operations, it is usually carried out on corresponding processing equipment. Since the processing equipment has a certain height, at this time, most processing equipment is usually provided with a feed inlet, and a feeding mechanism is provided at the feed inlet. Common feeding mechanisms include screw feeders, etc. During some rice processing operations, it is generally necessary to control the processing amount of each processing to facilitate subsequent comparison and packaging operations.

[0003] However, when using a screw feeder for feeding operations, the screw feeder generally can work continuously. When specifically controlling the amount of raw materials, it is generally controlled manually according to the conveyed amount. And after manually judging that the added amount of raw materials reaches the standard, the screw feeder is stopped and started again to complete metering processing. However, this type of operation depends on manual judgment and is inaccurate, and it is also rather troublesome to start and stop the screw feeder multiple times in the middle, and it will also affect the service life of the screw feeder, bringing inconvenience to users. In view of this, we have proposed a feeding mechanism with a metering function. Content of the Utility Model

[0004] The purpose of the utility model is to provide a feeding mechanism with a metering function to solve the defects mentioned in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

There are two symmetrically arranged loading cylinders above the bearing plate. A conical hopper is fixedly installed at the bottom end of the loading cylinder. A discharge pipe is fixedly installed at the bottom end of the conical hopper. A first discharge valve is fixedly installed on the discharge pipe. A plurality of support rods arranged in an annular and equally spaced manner are fixedly installed at the bottom of the loading cylinder. A weighing sensor is fixedly installed between the support rod and the upper surface of the bearing plate. The discharge pipe extends into the discharge box. A screw feeder is arranged above the loading cylinder. Two symmetrically arranged vertical pipes are fixedly installed at the bottom of the cylinder body of the screw feeder. The vertical pipes are inserted into the corresponding loading cylinders. A second discharge valve is fixedly installed on the vertical pipes.

[0007] Preferably, there are two symmetrically arranged through holes on the bearing plate. The conical hopper and the discharge pipe pass through the through holes.

[0008] Preferably, a plurality of support legs arranged in a matrix are fixedly installed at the bottom of the bearing plate, and the height of the support legs is 1.2 m to 1.4 m.

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] Please refer to Figures 1-4 , the present invention provides a technical solution: a feeding mechanism with a metering function, including a bearing plate 1, a discharge box 2 is arranged at the bottom of the bearing plate 1, and two symmetrically arranged holding cylinders 3 are arranged above the bearing plate 1. A conical hopper 32 is fixedly installed at the bottom end of the holding cylinder 3, a discharge pipe 33 is fixedly installed at the bottom end of the conical hopper 32, and a first discharge valve 34 is fixedly installed on the discharge pipe 33. A plurality of support rods 30 arranged in an annular and equally spaced manner are fixedly installed at the bottom of the holding cylinder 3, and a weighing sensor 31 is fixedly installed between the support rods 30 and the upper surface of the bearing plate 1 to realize the weighing operation using the weighing sensor 31;

[0028] Specifically, the discharge pipe 33 extends into the discharge box 2, a screw feeder 4 is arranged above the holding cylinder 3, and two symmetrically arranged vertical pipes 42 are fixedly installed at the bottom of the cylinder body of the screw feeder 4. The vertical pipes 42 are inserted into the corresponding holding cylinders 3, and a second discharge valve 43 is fixedly installed on the vertical pipes 42 to realize the addition operation of rice raw materials using the screw feeder 4.

[0029] In this embodiment, two symmetrically arranged through holes 10 are arranged on the bearing plate 1, and the conical hopper 32 and the discharge pipe 33 pass through the through holes 10 to realize normal erection operation.

[0030] Specifically, a plurality of support legs 11 arranged in a matrix are fixedly installed at the bottom of the supporting plate 1, and the height of the support legs 11 is 1.2m to 1.4m; a support pad 12 is fixedly installed at the bottom end of the support leg 11, and the support pad 12 is fixedly installed on the external frame by a plurality of fastening bolts to achieve stable supporting operation.

[0031] Furthermore, two mutually symmetrical control hosts 13 are fixedly installed on the front side of the carrying plate 1. The weighing value of the weighing sensor 31 is displayed on the control host 13. Specifically, a corresponding value is set in the control host 13. When the weighing value of the weighing sensor 31 reaches the standard, the control host 13 will control the corresponding second discharge valve 43 to close, and the corresponding vertical pipe 42 will not drop rice, so that the amount of rice in the filling cylinder 3 can reach the standard value, and the amount control operation is completed;

[0032] Finally, it should be noted that the control host 13, the second discharge valve 43 and the first discharge valve 34 of the utility model are all universal standard parts or parts known to technical personnel in this field, and their structures and principles are all known to technical personnel in this field through technical manuals or through conventional experimental methods. In the idle space of the device, all the above-mentioned electrical components, which refer to power elements, electrical components, and adaptive controllers and power supplies, are connected through wires. The specific connection means should refer to the working principle of the utility model. The electrical connection between each electrical component is completed in a sequential working order, and the detailed connection means are all well-known technologies in the field.

[0033] In addition, a discharge hopper 20 is fixedly installed at the bottom end of the discharge box 2, and an external discharge pipe 21 is fixedly installed at the bottom end of the discharge hopper 20, so that the rice can be discharged along the external discharge pipe 21 to the corresponding processing equipment outside for processing.

[0034] It is worth noting that a feed pipe 40 is fixedly installed at the feed end of the screw feeder 4 , and a feed cylinder 41 is fixedly installed at the top of the feed pipe 40 to facilitate the feeding operation into the screw feeder 4 .

[0035] It is worth noting that the inner walls of the discharge hopper 20 and the conical hopper 32 are both inclined downward by 45° to 60°, so that the rice can fall along the inner walls of the discharge hopper 20 and the conical hopper 32 more smoothly.

[0036] When the feeding mechanism with the metering function of the present utility model is in use, raw materials are added into the feeding cylinder 41. One of the second discharge valves 43 and two first discharge valves 34 are closed. The screw feeder 4 is connected to an external power supply and operated. When the screw feeder 4 is operating, rice is conveyed to the other vertical pipe 42 and drops out. At this time, the dropped rice can fall into the corresponding receiving cylinder 3. The weighing sensor 31 weighs the receiving cylinder 3. When the weight in the receiving cylinder 3 meets the requirements, the second discharge valve 43 is closed, and at the same time, the other second discharge valve 43 is opened. The corresponding rice drops along the other vertical pipe 42 into another receiving cylinder 3, and the raw material addition operation continues;

[0037] After the first discharge valve 34 at the bottom of the receiving cylinder 3 with the corresponding weighed amount is opened, the rice in the receiving cylinder 3 can fall into the discharge box 2 and be discharged outward through the discharge hopper 20 and the discharge pipe 21, which facilitates the use of the emptied receiving cylinder 3 to continue the next receiving operation.

[0038] The above shows and describes the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the present utility model and are not used to limit the present utility model.
