Description

Technical Field

[0001] This utility model relates to the field of cement pole processing technology, specifically to a sand and gravel screening device for cement pole processing. Background Technology

[0002] Cement utility poles are poles used to carry power lines. They are sturdy, durable, corrosion-resistant, temperature-resistant, high-strength, crack-resistant, and have a smooth and beautiful appearance, which is conducive to urban beautification. However, the processing of cement utility poles requires the use of sand and gravel raw materials. In order to ensure that the sand and gravel achieve a reasonable particle size ratio when used, the sand and gravel need to be screened to separate impurities, soil, and excessively small stones from the raw materials.

[0003] Currently, when screening sand and gravel, the feeding position of the sand and gravel is fixed, resulting in the sand and gravel falling onto the filter plate in a fixed position. This leads to low uniformity of sand and gravel feeding, causing them to accumulate during screening. Consequently, the filter plate is prone to severe wear in a single area during operation, affecting screening. Furthermore, the screened mud and other substances are easily dispersed in the air, polluting the working environment. Therefore, we propose a sand and gravel screening device for cement power pole processing to solve the above-mentioned problems. Utility Model Content

[0004] The purpose of this utility model is to provide a sand and gravel screening device for cement power pole processing, so as to solve the problem mentioned in the background art that the filter plates on the market are prone to severe wear in a single area during operation, and the screened soil and other materials are easy to disperse in the air and pollute the working environment.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sand and gravel screening device for cement power pole processing, comprising a housing, a conveyor belt arranged below the housing, and a feeding port connected to the upper end of the housing;

[0006] A motor is installed on the top of the housing, and a connecting frame is connected to the output end of the motor. A filter plate is installed at the lower end of the connecting frame, and a limit ring is connected to the outer side of the filter plate.

[0007] A second magnet is installed on the lower side of the connecting frame;

[0008] A discharge pipe is installed in the middle of the lower end of the housing, a discharge port is opened on the side of the discharge pipe, an installation plate is installed at the upper end of the discharge pipe, and a material distribution rod is installed on the lower side of the installation plate.

[0009] A baffle is installed on the outer side of the discharge pipe.

[0010] Preferably, a spring is connected to the upper side of the mounting plate, a striking rod is connected to the end of the spring, and a first magnet is installed at the upper end of the striking rod.

[0011] Preferably, the filter plate forms a rotating structure with the housing through a limiting ring, the upper side of the filter plate is inclined, and the filter plate is inclined towards the discharge pipe.

[0012] Preferably, the lowest point of the discharge port is flush with the lowest point of the upper side of the filter plate, and the filter plate is located above the baffle.

[0013] Preferably, the lower section of the striking rod has an "n" shaped structure, and the striking rod, the material distribution rod, and the mounting plate form an up-and-down sliding structure.

[0014] Preferably, the positions of the first magnet and the second magnet are arranged corresponding to each other, and the first magnet and the second magnet are magnets with the same poles.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] (1) The sand and gravel screening device for cement pole processing can make sand and gravel evenly fed onto the filter plate for screening by controlling the rotation of the filter plate, avoiding severe wear in a single position of the filter plate. In addition, the centrifugal force of the rotation of the filter plate makes the sand and gravel screened more quickly and avoids the filter plate from clogging.

[0018] (3) The cement pole processing sand and gravel screening device uses an inclined baffle to guide the separated soil impurities and concentrate them into the machine casing. The baffle prevents soil and dust from entering the working environment. Attached Figure Description

[0026] 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.

[0027] Please see Figures 1-6 The present invention provides the following technical solution: a sand and gravel screening device for cement power pole processing, including a housing 1, a conveyor belt 2 is provided below the housing 1, and a feeding port 3 is connected to the upper end of the housing 1; a motor 4 is installed above the housing 1, a connecting frame 5 is connected to the output end of the motor 4, a filter plate 6 is installed at the lower end of the connecting frame 5, and a limit ring 7 is connected to the outer side of the filter plate 6.

[0028] Furthermore, the filter plate 6 forms a rotating structure with the housing 1 through the limiting ring 7. The upper side of the filter plate 6 is inclined and the filter plate 6 is inclined towards the discharge pipe 8. By driving the filter plate 6 to rotate, the sand and gravel can be evenly fed onto the filter plate 6 for filtration. The inclined distribution of the filter plate 6 can also transport the screened sand and gravel towards the discharge pipe 8.

[0029] A discharge pipe 8 is installed in the middle of the lower end of the casing 1. A discharge port 9 is opened on the side of the discharge pipe 8. An installation plate 10 is installed at the upper end of the discharge pipe 8. A material distribution rod 11 is installed on the lower side of the installation plate 10. A baffle 15 is installed on the outer side of the discharge pipe 8.

[0030] Furthermore, the lowest point of the discharge port 9 is flush with the lowest point of the upper side of the filter plate 6. The filter plate 6 is located above the baffle 15, which allows the screened sand and gravel to enter the discharge pipe 8 from the discharge port 9 and be discharged.

[0031] A second magnet 16 is installed on the lower side of the connecting frame 5;

[0032] Furthermore, a spring 12 is connected to the upper side of the mounting plate 10, and a striking rod 13 is connected to the end of the spring 12. A first magnet 14 is installed at the upper end of the striking rod 13.

[0033] Furthermore, the lower section of the striking rod 13 has an "n" shaped structure. The striking rod 13, the material distribution rod 11, and the mounting plate 10 form an up-and-down sliding structure, which allows the striking rod 13 and the material distribution rod 11 to not affect each other's work. The striking rod 13 is used to strike the filter plate 6.

[0034] Furthermore, the positions of the first magnet 14 and the second magnet 16 are arranged corresponding to each other. The first magnet 14 and the second magnet 16 are magnets with the same poles. By utilizing the repulsive force between the magnets and the elastic force of the spring 12, the reciprocating movement of the striking rod 13 is realized, so as to successfully strike the filter plate 6.

[0035] Specifically, when using this cement pole processing sand and gravel screening device, the sand and gravel raw materials are fed into the feed port 3, and the sand and gravel enter the machine casing 1 and fall onto the filter plate 6. The motor 4 is connected to the power supply, and the connecting frame 5 connected to the output end is rotated, thereby controlling the rotation of the filter plate 6. At this time, the filter plate 6 rotates in the machine casing 1 through the limit ring 7 to ensure the stable rotation of the filter plate 6, so that the sand paper can be evenly fed onto the filter plate 6. The centrifugal force of the rotation of the filter plate 6 is used to prevent it from clogging. Small particles of stones and impurities such as mud fall through the mesh of the filter plate 6 and are concentrated in the machine casing 1 along the baffle 15. The baffle 15 prevents soil and dust from entering the working environment. As the filter plate 6 rotates, the material distribution rod 11 moves the sand and gravel, so that the sand and gravel are separated from impurities such as mud, improving its screening efficiency.

[0036] When the second magnet 16 on the connecting frame 5 moves to correspond with the position of the first magnet 14, the first magnet 14 and the second magnet 16, which are distributed with the same poles, repel each other, driving the striking rod 13 to move downward. The striking rod 13 compresses and stores force on the spring 12, causing the striking rod 13 to strike the filter plate 6. The striking force causes the filter plate 6 to vibrate, further accelerating the separation of sand and soil and further preventing the filter plate 6 from clogging. When the positions of the first magnet 14 and the second magnet 16 are misaligned, the spring 12 can control the striking rod 13 to return to its original position for subsequent... Continuing to utilize the repulsive force between the magnets, the striking rod 13 continues to strike the filter plate 6. As the filter plate 6 rotates, the filtered sand and gravel move to the discharge port 9 and are concentrated at the discharge port 9 along the inclined surface of the filter plate 6. Then, it is discharged from the discharge pipe 8 and falls onto the conveyor belt 2. The conveyor belt 2 is powered on to transport the sand and gravel. Subsequently, the sealed door on the lower left of the casing 1 can be opened to clean the separated mud and other impurities. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0037] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
