High-precision weighing anti-interference structure of feed batching scale

Abstract

This utility model discloses a high-precision weighing and anti-interference structure for a feed batching scale, including a fixed plate. Support rods are fixedly installed around the bottom of the fixed plate, and the feed batching scale body for weighing is installed through the surface of the fixed plate. Utilizing an anti-vibration mechanism, when the device vibrates, the rubber buffer pad and the base plate cushion the sliding rod and support rod. Simultaneously, the rubber seat and damping rod between the sliding rod and support rod further suppress the vibration, preventing it from being transmitted to the interior of the fixed plate and affecting the feed batching scale body. Furthermore, the sliding connection between the support rod and the sliding rod allows for further vibration reduction through the elastic connection between the rubber column and the spring when the vibration is too strong. This buffering and vibration reduction prevents excessive vibration from affecting the weighing accuracy of the feed batching scale body.

Description

Technical Field

[0001] This utility model relates to the field of batching scale technology, specifically a high-precision weighing and anti-interference structure for feed batching scales. Background Technology

[0002] A batching scale is a weighing instrument used to measure the proportions of several substances in a given batch. In feed production, two or more materials are weighed a certain number of times to form a batch, which is then guided onto the scale body of the batching scale by a feeding device for weighing.

[0003] In the prior art, as shown in the authorized announcement number "CN221661527U", a feed batching scale for rapid feeding can prevent raw materials from clumping, thus avoiding blockages and slowing down the feeding process.

[0004] However, existing technologies still have significant shortcomings, such as:

[0005] In the existing technology: Since the batching scale inevitably vibrates during operation, but its bottom is not equipped with a corresponding shock-absorbing structure, the batching scale is easily affected by vibration during use. Vibration interference will significantly affect the measurement accuracy of the batching scale, causing deviations in the weighing of raw materials, and ultimately adversely affecting the overall batching accuracy. Utility Model Content

[0008] The seismic-resistant mechanism includes a sliding rod that runs through the inside of a support rod. A buffer plate is fixedly installed at the bottom end of the sliding rod. A rubber buffer pad for shock absorption is fixedly installed at the bottom of the buffer plate. A base plate is fixedly installed at the bottom of the rubber buffer pad.

[0009] A shock-absorbing component is installed at the top of the inner cavity of the support rod to further improve the shock resistance of the feed batching scale body.

[0010] A feeding mechanism is installed on the top of the fixed plate to convey the ingredients into the hopper.

[0012] A spring is fixedly installed between the rubber seat and the damping rod, and the spring is sleeved on the surface of the rubber column.

[0013] Preferably, a mounting plate is fixedly installed on the bottom of the surface of the support rod, and screws are fixedly installed on both sides of the top of the buffer plate, with the top ends of the two screws penetrating the mounting plate and extending to the top of the mounting plate, and bolts are threaded onto the surface of the screws;

[0014] A rubber sheet is installed between the bolt and the mounting plate, and the rubber sheet is sleeved on the surface of the screw.

[0015] Preferably, the feeding mechanism includes two vertical rods fixedly installed on both sides of the top of the fixed plate, and a support plate is fixedly installed at the top of each of the two vertical rods. A feeding hopper is installed on the top of the feed batching scale body, and a conveying cylinder is fixedly installed on both sides of the top of the support plate.

[0016] Both conveying cylinders have a feeding pipe connected to one side of their tops for feeding, and both conveying cylinders have a discharge pipe connected to one side of their bottoms for discharging. The bottom end of the discharge pipe passes through the support plate and extends into the interior of the discharge hopper. A rotating rod is rotatably installed inside both conveying cylinders. A first spiral conveying blade is installed on the surface of the rotating rod. A drive motor is fixedly installed at one end of one conveying cylinder, and the output end of the drive motor passes through the conveying cylinder and is fixedly connected to a rotating rod.

[0017] Preferably, one adjacent end of each of the two rotating rods passes through the conveying cylinder and extends into the interior of the conveying cylinder. One adjacent end of each of the two rotating rods is fixedly installed with a driving bevel gear. A stirring rod is provided inside the hopper. The top end of the stirring rod passes through the support plate and extends to the top of the support plate. A driven bevel gear is fixedly installed at the top end of the stirring rod, and the two driving bevel gears are meshed with the driven bevel gear. A stirring blade is fixedly installed on the surface of the stirring rod located inside the hopper.

[0018] Preferably, a vertical pipe connects the hopper and the feed batching scale body, the bottom end of the stirring rod passes through the vertical pipe and extends into the interior of the vertical pipe, and a second spiral conveying blade is installed on the surface of the stirring rod.

[0019] Preferably, a protective shell is fixedly installed on the top of the support plate and between the two conveying cylinders, and the protective shell covers the surfaces of the driving bevel gear and the driven bevel gear to protect the driving bevel gear and the driven bevel gear.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] 1. By utilizing the anti-vibration mechanism, when the device vibrates, the rubber buffer pad and the base plate cushion the slide rod and support rod. At the same time, the rubber seat and damping rod between the slide rod and the support rod further suppress the vibration, preventing it from being transmitted to the interior of the fixed plate and affecting the feed weighing scale body. Furthermore, through the sliding connection between the support rod and the slide rod, the elastic connection between the rubber column and the spring can further enhance the shock absorption performance of the feed weighing scale body when the vibration force is too large. This can buffer and reduce the vibration of the feed weighing scale body, preventing excessive vibration force from affecting the weighing accuracy of the feed weighing scale body.

[0022] 2. During the batching and weighing process, the raw materials in the corresponding raw material chamber are added to the inside of the feeding cylinder through the feeding pipe, and the drive motor is turned on to start working, driving the rotating rod and the first spiral conveying blade to rotate. The raw materials inside the feeding cylinder are added to the inside of the feeding hopper through the feeding pipe. At the same time as the rotating rod rotates, it drives the active bevel gear to rotate. The active bevel gear, through meshing with the driven bevel gear, drives the stirring rod and stirring blade to rotate, stirring and mixing the raw materials inside the feeding hopper. At the same time as the stirring rod rotates, the second spiral conveying blade on its surface rotates synchronously, conveying the raw materials inside the feeding hopper to the inside of the feed batching scale body through the vertical pipe for weighing. This can convey the raw materials and prevent them from clumping, which could cause blockage in the feeding hopper. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figures 1-6 This utility model provides a technical solution: a high-precision weighing anti-interference structure for a feed batching scale, including a fixed plate 1, with support rods 2 fixedly installed around the bottom of the fixed plate 1, and a feed batching scale body 3 for weighing installed through the surface of the fixed plate 1. An anti-vibration mechanism 4 is installed at the bottom of each of the four support rods 2 to provide anti-vibration for the feed batching scale body 3.

[0032] The seismic mechanism 4 includes a slide bar 41 that runs through the inside of the support rod 2. A buffer plate 42 is fixedly installed at the bottom end of the slide bar 41. A rubber buffer pad 43 for shock absorption is fixedly installed at the bottom of the buffer plate 42. A base plate 44 is fixedly installed at the bottom of the rubber buffer pad 43.

[0033] A shock-absorbing component 45 is installed at the top of the inner cavity of the support rod 2 to further improve the shock resistance of the feed batching scale body 3;

[0034] A feeding mechanism 5 is installed on the top of the fixed plate 1 for conveying the ingredients into the inside of the feeding hopper 53.

[0035] Reference Figure 1 , Figure 2 as well as Figure 3As shown, the shock absorption assembly 45 includes a rubber seat 451 fixedly installed on one end of the slide rod 41 located inside the support rod 2. A rubber column 452 is fixedly installed on the top of the rubber seat 451. A spring 454 is fixedly installed on the telescopic end of the rubber column 452, and the top end of the spring 454 is fixedly connected to the top of the inner cavity of the support rod 2.

[0036] A spring 454 is fixedly installed between the rubber seat 451 and the damping rod 453, and the spring 454 is sleeved on the surface of the rubber column 452.

[0037] In this embodiment, when the device vibrates, the rubber buffer pad 43 and the base plate 44 buffer the slide rod 41 and the support rod 2. At the same time, the rubber seat 451 and the damping rod 453 between the slide rod 41 and the support rod 2 further suppress the vibration, so as to prevent the vibration from being transmitted to the interior of the fixed plate 1 and affecting the feed weighing scale body 3. Furthermore, through the sliding connection between the support rod 2 and the slide rod 41, the elastic connection between the rubber column 452 and the spring 454 can further improve the shock absorption performance of the feed weighing scale body 3 when the vibration force is too large. In this way, the feed weighing scale body 3 can be buffered and damped, so as to avoid the situation where the vibration force is too large and affects the weighing accuracy of the feed weighing scale body 3.

[0038] Reference Figure 2 as well as Figure 3 As shown, a mounting plate 455 is fixedly installed on the bottom of the surface of the support rod 2, and screws 456 are fixedly installed on both sides of the top of the buffer plate 42. The top ends of the two screws 456 penetrate the mounting plate 455 and extend to the top of the mounting plate 455. Bolts 457 are threadedly connected to the surface of the screws 456.

[0039] A rubber sheet 458 is installed between the bolt 457 and the mounting plate 455, and the rubber sheet 458 is sleeved on the surface of the screw 456;

[0040] In this embodiment, the threaded connection between the bolt 457 and the screw 456 allows the mounting plate 455 to be pressed down by rotating the bolt 457, so as to adjust the pressure between the rubber column 452 and the spring 454, which facilitates the subsequent shock absorption of the feed batching scale body 3.

[0041] Reference Figure 1 , Figure 4 as well as Figure 5 As shown, the feeding mechanism 5 includes two vertical rods 51 fixedly installed on both sides of the top of the fixed plate 1, and a support plate 52 is fixedly installed at the top of each of the two vertical rods 51. A feeding hopper 53 is installed on the top of the feed batching scale body 3, and a conveying cylinder 54 is fixedly installed on both sides of the top of the support plate 52.

[0042] Each of the two conveying cylinders 54 has a feeding pipe 55 connected to one side of its top for feeding, and a discharge pipe 56 connected to one side of its bottom for discharging. The bottom end of the discharge pipe 56 passes through the support plate 52 and extends into the interior of the discharge hopper 53. A rotating rod 57 is rotatably installed inside the two conveying cylinders 54. A first spiral conveying blade 58 is installed on the surface of the rotating rod 57. A drive motor 59 is fixedly installed at one end of one conveying cylinder 54, and the output end of the drive motor 59 passes through the conveying cylinder 54 and is fixedly connected to a rotating rod 57.

[0043] In this embodiment, during the batching and weighing process, the raw materials in the corresponding raw material chamber are added into the inside of the conveying cylinder 54 through the feeding pipe 55, and the drive motor 59 is turned on to work, driving the rotating rod 57 and the first spiral conveying blade 58 to rotate, and the raw materials inside the conveying cylinder 54 are added into the inside of the feeding hopper 53 through the feeding pipe 56.

[0044] Reference Figure 4 as well as Figure 5 As shown, the adjacent ends of the two rotating rods 57 both penetrate the conveying cylinder 54 and extend into the interior of the conveying cylinder 54. The adjacent ends of the two rotating rods 57 are fixedly installed with driving bevel gears 501. The interior of the hopper 53 is provided with a stirring rod 502. The top end of the stirring rod 502 penetrates the support plate 52 and extends to the top of the support plate 52. The top end of the stirring rod 502 is fixedly installed with a driven bevel gear 503. The two driving bevel gears 501 and the driven bevel gear 503 are meshed and connected. The surface of the stirring rod 502 located inside the hopper 53 is fixedly installed with stirring blades 504.

[0045] In this embodiment, while the rotating rod 57 is rotating, it simultaneously drives the active bevel gear 501 to rotate. The active bevel gear 501, through meshing with the driven bevel gear 503, drives the stirring rod 502 and the stirring blade 504 to rotate, stirring and mixing the raw materials inside the hopper 53. At the same time as the stirring rod 502 rotates, the second spiral conveying blade 506 on its surface rotates synchronously, conveying the raw materials inside the hopper 53 through the vertical pipe 505 into the feed batching scale body 3 for weighing.

[0046] Reference Figure 5 as well as Figure 6 As shown, a vertical pipe 505 connects the hopper 53 and the feed batching scale body 3. The bottom end of the stirring rod 502 passes through the vertical pipe 505 and extends into the interior of the vertical pipe 505. A second spiral conveying blade 506 is installed on the surface of the stirring rod 502.

[0047] In this embodiment, the second spiral conveying blade 506 can be rotated simultaneously while the stirring rod 502 rotates. As the second spiral conveying blade 506 rotates, it uses its own shape to transport the raw materials inside the hopper 53 to the inside of the feed batching scale body 3 for weighing.

[0048] Reference Figure 4 As shown, a protective shell is fixedly installed on the top of the support plate 52 and between the two feed cylinders 54, and the protective shell covers the surfaces of the driving bevel gear 501 and the driven bevel gear 503 to protect the driving bevel gear 501 and the driven bevel gear 503.

[0049] Working principle: During the batching and weighing process, the raw materials in the corresponding raw material chamber are added into the inside of the feeding cylinder 54 through the feeding pipe 55, and the drive motor 59 is turned on to work, driving the rotating rod 57 and the first spiral conveying blade 58 to rotate, and the raw materials inside the feeding cylinder 54 are added into the inside of the feeding hopper 53 through the feeding pipe 56. At the same time as the rotating rod 57 rotates, it synchronously drives the active bevel gear 501 to rotate. The active bevel gear 501, through meshing with the driven bevel gear 503, drives the stirring rod 502 and the stirring blade 504 to rotate, stirring and mixing the raw materials inside the feeding hopper 53. At the same time as the stirring rod 502 rotates, the second spiral conveying blade 506 on its surface rotates synchronously, and the raw materials inside the feeding hopper 53 are conveyed into the inside of the feed batching scale body 3 through the vertical pipe 505 for weighing.

[0050] When the device vibrates, the rubber buffer pad 43 and the base plate 44 buffer the slide rod 41 and the support rod 2. At the same time, the rubber seat 451 and the damping rod 453 between the slide rod 41 and the support rod 2 further suppress the vibration, so as to prevent the vibration from being transmitted to the interior of the fixed plate 1 and affecting the feed batching scale body 3. Furthermore, through the sliding connection between the support rod 2 and the slide rod 41, the elastic connection between the rubber column 452 and the spring 454 can further improve the shock absorption performance of the feed batching scale body 3 when the vibration force is too large.

[0051] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
