Description

TECHNICAL FIELD

[0001] The utility model belongs to alloy pellet processing screening device related technical field, concretely relates to a kind of alloy pellet processing screening device for train axle connecting piece surface shot blasting. BACKGROUND

[0002] Train axle connecting piece is crucial in railway transportation, and its surface shot blasting treatment can improve performance and service life. The quality of shot blasting alloy pellets directly affects the shot blasting effect and requires precise processing and screening. Existing alloy pellet processing and screening devices have insufficient precision and low efficiency, making it difficult to meet the production needs of high-quality train axle connecting pieces. Therefore, it is urgent to develop an efficient and precise alloy pellet processing and screening device for train axle connecting piece surface shot blasting to effectively solve the above problems and ensure railway transportation safety.

[0003] In traditional alloy pellet screening equipment, static screening is usually used, and alloy pellets fall through the screen mesh by their own gravity or move on the screen surface through simple vibration. This method limits the contact opportunities between alloy pellets and screen holes, and a large number of alloy pellets are easily stacked together, resulting in slow screening speed and low processing efficiency, which cannot meet the screening efficiency requirements of large-scale production. UTILITY MODEL CONTENTS

[0004] The utility model aims to provide an alloy pellet processing and screening device for train axle connecting piece surface shot blasting to solve the problem of slow screening speed and low processing efficiency in traditional alloy pellet screening equipment, which usually uses static screening method, and alloy pellets fall through the screen mesh by their own gravity or move on the screen surface through simple vibration. This method limits the contact opportunities between alloy pellets and screen holes, and a large number of alloy pellets are easily stacked together, resulting in slow screening speed and low processing efficiency, which cannot meet the screening efficiency requirements of large-scale production.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: an alloy pellet processing and screening device for train axle connecting piece surface shot blasting, comprising a main cabinet, a screening chamber arranged at the right side of the main cabinet, and a base arranged at the bottom of the main cabinet.

[0006] A hopper is arranged at the upper side of the base, and a drive motor connected to an external power supply for power supply is arranged at the left outer position of the base.

[0007] A screening cylinder is arranged at the upper side of the screening chamber, and a threaded spindle is arranged at the middle position of the screening cylinder and connected to the drive motor transmission shaft.

[0008] A plurality of screening cavities are arranged at the lower side of the screening chamber, and a screening opening is arranged at the front side of each screening cavity.

[0009] The left end of the screen cylinder is provided with a baffle, and the front and rear ends of the threaded main shaft are respectively provided with two slide rods.

[0010] The left end of the screen cylinder is provided with a baffle, and the front and rear ends of the threaded main shaft are respectively provided with two slide rods.

[0011] Preferably, the moving plate is connected with the threaded main shaft through a threaded connection mode, and the two slide rods are respectively connected with the moving plate through a penetrating connection mode.

[0012] Preferably, the moving plate is connected with the threaded main shaft through a threaded connection mode, and the two slide rods are respectively connected with the moving plate through a penetrating connection mode.

[0013] Preferably, the moving plate is connected with the threaded main shaft through a threaded connection mode, and the two slide rods are respectively connected with the moving plate through a penetrating connection mode.

[0014] Preferably, the moving plate is connected with the threaded main shaft through a threaded connection mode, and the two slide rods are respectively connected with the moving plate through a penetrating connection mode.

[0016] Preferably, the moving plate is connected with the threaded main shaft through a threaded connection mode, and the two slide rods are respectively connected with the moving plate through a penetrating connection mode.

[0017] Compared with the prior art, the alloy ball processing and screening device for train shaft connecting piece surface shot blasting has the following beneficial effects:

[0018] 1. In the traditional screening, alloy balls are prone to static accumulation, and part of them cannot be in contact with the screen hole in time. The reciprocating pushing of the moving plate makes the alloy balls continuously roll and move in the screen cylinder, greatly increasing the contact opportunity of each alloy ball with the screen hole. Alloy balls that may be blocked can also reach the screen hole position through the pushing of the moving plate. Compared with static screening, this dynamic screening method can complete the screening of a large number of alloy balls in a shorter time, improve the screening amount per unit time, and speed up the screening process.

[0019] 2. Alloy balls of different sizes are randomly distributed in the screen cylinder, and the reciprocating pushing of the moving plate makes the alloy balls move more uniformly and disorderly, which helps to more accurately distinguish alloy balls of different sizes. It avoids screening errors caused by uneven distribution of alloy balls, reduces the mixing caused by mutual extrusion and accumulation of alloy balls of different sizes, realizes more thorough separation, and improves the purity and quality of the alloy balls after screening.

[0020] 3. During the screening process, the sieve holes are easily clogged, affecting the screening effect. The reciprocating motion of the moving plate can dislodge the alloy pellets clogging the sieve holes, keeping them clear. At the same time, alloy pellets tend to accumulate in corners or areas within the screening cylinder. The reciprocating motion of the moving plate can cover these areas, pushing the accumulated alloy pellets to the vicinity of the sieve holes, achieving comprehensive screening, avoiding screening dead zones, and ensuring the consistency and integrity of the screening effect.

[0021] In addition, the baffle installed inside the left end of the screening cylinder and connected to the screening cylinder by threads always remains in a fixed position, effectively preventing the alloy pellets from falling from the left end of the screening cylinder and ensuring that the alloy pellets are screened according to a predetermined path inside the screening cylinder. It works in conjunction with other innovative structures to jointly ensure the stability and accuracy of the screening work. Attached Figure Description

[0029] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0030] The utility model provides a kind of alloy ball processing screening device for train axle connecting piece surface shot blasting as Figures 1-6 As shown in a kind of alloy ball processing screening device for train axle connecting piece surface shot blasting, including main cabinet 4, the base being set at the bottom of main cabinet 4, and the sieve chamber 9 being set at the right side position of main cabinet 4;

[0031] Funnel 3 is arranged at the upper side position of base 1, and driving motor 2 for supplying power is arranged at the left outer position of base 1;

[0032] Screening cylinder 7 is arranged at the upper side position of sieve chamber 9, and screw spindle 12 is arranged at the middle position of screening cylinder 7 and connected with the transmission shaft of driving motor 2;

[0033] A plurality of screening cavities 15 are arranged at the lower side position of sieve chamber 9, and screening port 10 is arranged at the front side position of the plurality of screening cavities 15;

[0034] Baffle 6 is arranged at the left end inner position of screening cylinder 7, and two slide rods 14 are horizontally arranged at the front and rear ends of screw spindle 12 respectively;

[0035] Mobile plate 13 is arranged at the left outer position of screw spindle 12 and the two slide rods 14.

[0036] Base 1 is arranged at the lower side position of main cabinet 4, and universal wheel 11 is arranged at the right lower side position of sieve chamber 9.

[0037] In the embodiment, the alloy ball processing screening device for train axle connecting piece surface shot blasting mainly consists of main cabinet 4 and sieve chamber 9. Base 1 is arranged below main cabinet 4 to provide support and stability. Sieve chamber 9 is located at the right side of main cabinet 4, and universal wheel 11 is installed at the right lower side to facilitate the movement of the device. Driving motor 2 is installed at the left side of base 1 on main cabinet 4 to provide power for the device, and funnel 3 is arranged at the upper side to input the alloy balls to be screened.

[0038] The alloy balls are poured from above the funnel 3, and since the chute 5 extending into the interior of the screening cylinder 7 is arranged at the right lower side of the funnel 3, the alloy balls enter the interior of the screening cylinder 7 along the chute 5 under the action of gravity.

[0039] The driving motor 2 is connected with the threaded spindle 12. When the driving motor 2 is electrified, the threaded spindle 12 is driven to rotate. Since the threaded spindle 12 is connected with the screening cylinder 7 through the welding connection mode and connected with the screening chamber 9 through the sleeve embedding connection mode, the threaded spindle 12 drives the screening cylinder 7 to rotate in the screening chamber 9 when the threaded spindle 12 rotates.

[0040] The moving plate 13 is connected with the threaded spindle 12 through the threaded connection mode, and the two slide rods 14 are respectively connected with the moving plate 13 through the penetrating connection mode. The moving plate 13 is attached to the inner wall of the screening cylinder 7. When the threaded spindle 12 rotates, the moving plate 13 rotates on the threaded spindle 12 due to the threaded connection, and is limited by the slide rods 14 to move left and right along the direction of the slide rods 14. When the threaded spindle 12 is driven by the driving motor 2 to rotate reversely, the moving plate 13 moves reversely along the direction of the slide rods 14. The reciprocating movement of the moving plate 13 can push the alloy pellets at the bottom of the screening cylinder 7 reciprocally.

[0041] The screening cylinder 7 is provided with different size screen holes 8 in a circumferential array with the threaded spindle 12 as the center from left to right. During the rotation of the screening cylinder 7 and the reciprocating pushing of the moving plate 13 to the alloy pellets, different size alloy pellets will contact the screen holes 8 under the action of gravity and the pushing of the moving plate 13. The alloy pellets smaller than the size of the screen holes 8 will fall through the screen holes 8 and enter the screening cavities 15 below the screening chamber 9, and finally be discharged from the screening port 10.

[0042] The baffle 6 is installed at the inner position of the left end of the screening cylinder 7 through the threaded connection mode. It limits the position to prevent the alloy pellets from falling from the left end of the screening cylinder 7 and ensures that the alloy pellets are screened according to the predetermined screening path in the screening cylinder 7.

[0043] After being screened through the screen holes 8, alloy pellets of different sizes fall into the corresponding screening cavities 15, realizing the classification screening of the alloy pellets and completing the whole screening process.

[0044] As Figures 1-6As shown, the moving plate 13 is connected to the threaded spindle 12 by threaded connection, and the two sliding rods 14 are connected to the moving plate 13 by penetrating connection. The moving plate 13 is attached to the inner wall of the screening cylinder 7. The screening cylinder 7 is provided with different size screen holes 8 arranged in a circular array with the threaded spindle 12 as the center. The threaded spindle 12 is connected to the screening cylinder 7 by welding connection, and the threaded spindle 12 is connected to the screening chamber 9 by sleeve embedding connection. The driving motor 2 drives the threaded spindle 12 to rotate the screening cylinder 7 in the screening chamber 9. The moving plate 13 can move left and right on the threaded spindle 12 and the two sliding rods 14 by threaded rotation and sleeve connection. The baffle 6 is connected to the screening cylinder 7 by threaded connection. The funnel 3 is provided with a chute 5 extending into the interior of the screening cylinder 7.

[0045] Preferably, the driving motor starts to operate after being connected to an external power source, serving as a power source to drive the threaded spindle connected thereto to rotate. The threaded spindle can rotate clockwise or counterclockwise under the drive of the driving motor. Since it is firmly connected to the screening cylinder by welding, it will simultaneously drive the screening cylinder to rotate on the screening chamber.

[0046] At the same time, the moving plate is closely connected to the threaded spindle by threads, and is penetrated by the two sliding rods. When the threaded spindle rotates, the moving plate will move on the threaded spindle based on the threaded transmission principle. Due to the limiting and guiding effect of the sliding rods, the moving plate can only move left and right inside the screening cylinder along the direction of the sliding rods. When the threaded spindle reverses, the moving direction of the moving plate also changes, thereby realizing the reciprocating movement of the moving plate inside the screening cylinder.

[0047] During the left and right movement of the moving plate, it will continuously push the alloy pellets at the bottom of the screening cylinder to move and roll inside the screening cylinder. In this process, the alloy pellets are in full contact with the different size screen holes arranged in a circular array with the threaded spindle as the center on the screening cylinder. According to the screening principle, alloy pellets smaller than the size of the screen holes will fall through the screen holes and enter the screening cavity, thereby completing the screening process.

[0048] The baffle installed inside the left end of the screening cylinder and connected to the screening cylinder by threads remains in a fixed position throughout the process, playing a key limiting role. It effectively prevents the alloy pellets from falling from the left end of the screening cylinder, ensures that the alloy pellets are screened according to the predetermined path inside the screening cylinder, and ensures that the screening work is stable and accurate.

[0049] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application has been described in detail, for the skilled in the art, it still can be modified, or for part of the technical features of the equivalent replacement, the spirit and principles of the present application, made any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
