Description

Technical Field

[0001] This application relates to the field of sediment filtration technology, and in particular to an automatic stone removal device for a continuous ball conveyor belt. Background Technology

[0002] In the production process of ceramic enterprises, mud and sand are the main raw materials for the production of ceramic bricks. During the feeding process of ball milling, a loader needs to shovel the raw materials into the feeder, and then the materials are fed into the individual continuous balls for grinding via a conveyor belt.

[0003] During the production process, since the mud and sand are naturally mined, there are many stones mixed in during the mining process. Many large stones are removed by excavators and loaders during the raw material homogenization or transportation process. However, excavators and loaders cannot remove smaller stones from the mud and sand, resulting in many stones remaining in the mud and sand.

[0004] In existing technology, workers convey mud and sand mixed with stones into the continuous sphere via a conveyor belt. However, larger stones can easily clog the feed inlet of the continuous sphere, preventing subsequent mud and sand from entering and thus affecting production. Furthermore, cleaning the clogged feed inlet is extremely difficult, leading to high labor intensity for workers and potentially impacting production continuity and efficiency. Utility Model Content

[0034] Furthermore, the technical features involved in the different embodiments of the present invention described above can be combined with each other as long as they do not conflict with each other.

[0035] This utility model provides, for example Figures 1 to 4 The device shown is an automatic stone removal device for a continuous ball conveyor belt, which aims to solve the shortcomings of existing continuous ball conveyor belts that cannot remove stones.

[0036] This automatic stone removal device for a continuous ball conveyor belt is installed on a fixed component 520 spaced apart from the conveyor belt 510. The conveyor belt 510 moves along the X-axis. This automatic stone removal device mainly includes a lifting module 100 and a removal module 200. The lifting module 100 and the removal module 200 are respectively installed on the fixed component 520. The lifting module 100 is used to be lifted by foreign objects conveyed to the detection area on the conveyor belt 510, causing it to deviate, thereby determining whether there are foreign objects in the detection area (when the lifting module 100 deviates, it can be considered that there are foreign objects in the detection area). The removal module 200 is used to remove foreign objects from the conveyor belt 510 within the removal area.

[0037] The detection zone is located on conveyor belt 510, and the cleaning zone is located on conveyor belt 510 along the X-axis of the detection zone. It should be noted that the conveyor belt 510 transports mud and sand along the X-axis to the feed inlet of the continuous ball unit. Therefore, the mud and sand will first pass through the detection zone and then the cleaning zone. It is understood that the mud and sand contains stones, and to avoid clogging the feed inlet of the continuous ball unit, larger stones need to be removed. In this application, stones with a width greater than a preset width L along the Y-axis are called foreign objects and need to be removed to prevent clogging of the feed inlet of the continuous ball unit. In actual use, the preset width L can be set as needed, such as being equal to half the width of the feed inlet of the continuous ball unit along the Y-axis. The Y-axis is parallel to the plane of conveyor belt 510 but not parallel to the X-axis. Figure 1 As shown, the Y-axis direction is preferably perpendicular to the X-axis direction.

[0038] In existing technology, workers transport mud and sand mixed with stones to the continuous sphere via conveyor belt 510. However, larger stones can easily clog the feed inlet of the continuous sphere, preventing subsequent mud and sand from entering and thus affecting production. Furthermore, cleaning the feed inlet of the continuous sphere after stones clog it is very difficult, resulting in high labor intensity for workers and potentially impacting the continuity and efficiency of production.

[0039] This invention uses a lifting module 100 to detect stones in the mud and sand material in the detection area of ​​the conveyor belt 510. Before use, a preset width L can be set to the width of the feed inlet of the single continuous ball that is not easily blocked by stones. When the width of the stone is greater than the preset width L and the stone reaches the removal area, the stone can be removed by the removal module 200 to avoid the feed inlet of the single continuous ball being blocked and improve production efficiency.

[0040] In some embodiments, such as Figures 1 to 4 As shown, the lifting module 100 includes: a rake assembly 110, which includes:

[0041] Roller 111, the axial direction of roller 111 is set along the Y-axis and it rotates around the axis. Roller 111 is driven to move toward the detection area.

[0042] Several sets of roller nails 112 are respectively arranged on the roller 111 along the circumference of the roller 111. Any set of roller nails 112 is driven by a foreign object to move, so as to drive the roller 111 away from the detection area.

[0043] Specifically, the roller 111 moves towards the detection area under the force of gravity or the elasticity of the spring device. In actual use, the conveyor belt 510 is generally horizontal or has a small inclination. Preferably, the roller 111 moves towards the detection area under gravity, and several sets of rake spikes 112 surround the outer surface of the roller 111. The roller 111 contacts the conveyor belt 510 through the sets of rake spikes 112. In actual use, due to the friction between the sets of rake spikes 112 and the conveyor belt 510, the roller 111 and the sets of rake spikes 112 can roll on the conveyor belt 510 like a tire and its treads. Therefore, when the roller 111 and the sets of rake spikes 112 press against a stone on the conveyor belt 510 (detection area), they will bounce back. Figure 1 As described above, since the displacement path of the roller 111 (which can be an arc or a straight line) is restricted, the roller 111 will move away from the detection area, and the distance between the roller 111 and the conveyor belt 510 will be changed, thereby determining that there is a foreign object in the detection area.

[0044] It is understandable that the mud and sand are a solid-liquid mixture, and the roller nail assembly 112 will sink into it when it comes into contact with it. If there are no stones between the roller nail assembly 112 and the conveyor belt 510, the roller nail assembly 112 can directly pass through the mud and sand and press against the conveyor belt 510; however, if there are stones between the roller nail assembly 112 and the conveyor belt 510, the roller nail assembly 112 will press against the conveyor belt 510 through the stones. At this time, the presence of foreign objects in the detection area can be determined by observing the distance between the roller 111 and the conveyor belt 510.

[0045] In practical use, because the contact area of ​​the rake nail assembly 112 when it comes into contact with the mud and sand is small, it can more easily sink into the mud and sand. However, the contact area of ​​the roller 111 when it comes into contact with the mud and sand is large, making it difficult to sink into the mud and sand. If there are stones in the mud and sand, the displacement of the roller 111 is not obvious and the stones are not easily detected. Therefore, the length of the rake nail assembly 112 in the radial direction of the roller 111 can be set as needed (preferably greater than the thickness of the mud and sand in the direction perpendicular to the plane of the conveyor belt 510) to prevent the roller 111 from sinking into the mud and sand.

[0046] The rake nail group 112 includes: a plurality of rake nails 112a, which are spaced apart along the Y-axis direction, and the distance between any two adjacent rake nails 112a is a preset width L.

[0047] Specifically, when the roller 111 rolls, several sets of rake spikes 112 sequentially press against the conveyor belt 510. If the stone is small, it rolls easily when squeezed. When the stone rolls between two adjacent rake spikes 112a, if the width of the stone in the Y-axis direction is less than the distance between the two adjacent rake spikes 112a (preset width L), the stone will pass directly through the gap into the detection area and be judged as a non-foreign object. If the stone is large, it does not roll easily when squeezed. When the stone is between two adjacent rake spikes 112a, if the width of the stone in the Y-axis direction is greater than the distance between the two adjacent rake spikes 112a (preset width L), the stone cannot pass through the gap into the detection area, thus driving it to roll away from the conveyor belt 510 and be judged as a foreign object. Therefore, by controlling the preset width L, foreign objects can be "screened out".

[0048] In some embodiments, such as Figure 1 , Figure 2 as well as Figure 4 As shown, the lifting module 100 also includes a rake bracket 120, which includes a support rod 121, which is mounted on the fixing member 520.

[0049] The connecting rod 122 is rotatably connected to the support rod 121 and the roller 111 respectively, and the rotation axes of the support rod 121 and the roller 111 are parallel. The connecting rod 122 is driven to rotate, so as to drive the roller 111 to move towards the detection area.

[0050] Specifically, under the influence of the support rod 121 and the connecting rod 122, the roller 111 can only rotate along the rotation axis of the support rod 121, moving towards or away from the conveyor belt 510. Under the influence of gravity, the roller 111 will move towards the conveyor belt 510, thus pressing against it. When the conveyor belt 510 is working, it will drive the roller 111 to rotate. When the roller rake assembly 112 presses against a foreign object, the roller 111 experiences an upward force and will rotate along the rotation axis of the support rod 121, moving away from the conveyor belt 510, thus identifying the foreign object. Therefore, in practical use, the presence of a foreign object in the detection area can be determined by observing the distance between the roller 111 and the conveyor belt 510.

[0051] In some embodiments, such as Figure 1 , Figure 2 as well as Figure 4 As shown, the middle part of the connecting rod 122 is pivotally connected to the support rod 121, and one end of the connecting rod 122 is rotatably connected to the roller 111, while the other end forms a limiting part 123;

[0052] The roller 111 is driven to move away from the detection area, thereby causing the limiting part 123 to move toward the detection area. The limiting part 123 is used to contact the conveyor belt 510 to limit the rotation angle of the connecting rod 122.

[0053] Specifically, the connecting rod 122 is a straight rod, with its middle section pivotally connected to the support rod 121 to form a "seesaw" structure. One end of the "seesaw" is connected to the support rod 121, and the other end forms a limiting part 123. When the end of the support rod 121 facing the roller 111 is subjected to the gravity of the roller 111, it will move towards the conveyor belt 510, causing the roller 111 to press against the conveyor belt 510. At this time, the limiting part 123 will lift up and move away from the conveyor belt 510. When the roller rake nail assembly 112 presses down on a stone, the roller 111 will move away from the conveyor belt 510. At this time, the limiting part 123 will move towards the conveyor belt 510. Especially when the moving speed of the conveyor belt 510 is high, the roller 111 may bounce up forcefully and move away from the conveyor belt 510. When the limiting part 123 moves towards the conveyor belt 510 and comes into contact with the conveyor belt 510, the roller 111 cannot continue to move away from the conveyor belt 510, thereby preventing the roller 111 from leaving the detection area.

[0054] Preferably, a counterweight 430 is also included. The counterweight 430 is detachably mounted at the end of the connecting rod 122 facing the roller 111, so that the center of gravity of the connecting rod 122 is located between the support rod 121 and the roller 111. This allows the roller 111 to move toward the conveyor belt 510, pressing the roller 111 against the conveyor belt 510. In actual use, the weight of the counterweight 430 can be adjusted so that the rake nail assembly 112 can better penetrate the mud and sand and press against the conveyor belt 510, thereby more accurately determining whether there are foreign objects in the detection area.

[0055] In some embodiments, such as Figure 1 , Figure 2 as well as Figure 4 As shown, the automatic stone removal device for continuous ball conveyor belt also includes: photoelectric sensor module 410, which is mounted on the fixing member 520. The photoelectric sensor module 410 is used to sense the deviation of the lifting module 100 and to determine whether there are foreign objects in the detection area by detecting the position of the detection roller 111.

[0056] Specifically, when the lifting module 100 is lifted by a foreign object conveyed to the detection area by the conveyor belt 510 and becomes misaligned, the presence of a foreign object in the detection area can be determined by sensing whether the lifting module 100 has become misaligned. However, in order to avoid misjudgment due to slight misalignment of the lifting module 100 caused by vibration or other reasons, the position of the detection roller 111 can be detected by the photoelectric sensor module 410. Only when the roller 111 is misaligned to a preset position can it be determined that there is a foreign object in the detection area.

[0057] Preferably, the photoelectric sensor module 410 can be a camera, photoelectric sensor, Hall sensor, etc. In practice, the photoelectric sensor module 410 can detect that the roller 111 has moved away from the conveyor belt 510 by a certain distance or that the roller 111 has moved away from the conveyor belt 510 by more than a preset position (such as the minimum distance position between the roller 111 and the photoelectric sensor module 410), and then it can be considered that there is a foreign object in the detection area.

[0058] In some embodiments, such as Figure 1 , Figure 2 as well as Figure 4 As shown, the automatic stone removal device for the continuous ball conveyor belt also includes: a photoelectric sensor bracket 420, which is mounted on the fixing member 520; a photoelectric sensor module 410 is damped and slidably mounted on the photoelectric sensor bracket 420; and the moving path of the photoelectric sensor module 410 is parallel to the moving path of the roller 111.

[0059] Specifically, the position of the photoelectric sensor module 410 on the photoelectric sensor bracket 420 can be adjusted to better monitor the position of the roller 111. For example... Figure 4 As shown, the movement path of the photoelectric sensor module 410 is a straight line, which can effectively monitor the position of the roller 111. However, if the movement path of the photoelectric sensor module 410 is not parallel to the movement path of the roller 111, the minimum distance between the roller 111 and the photoelectric sensor module 410 will change after the operator adjusts the position of the photoelectric sensor module 410 on the photoelectric sensor bracket 420. Therefore, when the photoelectric sensor module 410 is a distance sensor such as a photoelectric sensor or a Hall sensor, the operator needs to calibrate the photoelectric sensor module 410 after adjusting its position on the photoelectric sensor bracket 420 before it can be used normally, which is quite troublesome. This application sets the movement path of the photoelectric sensor module 410 to be parallel to the movement path of the roller 111, thus avoiding the above problem.

[0060] In some embodiments, the automatic stone removal device for continuous ball conveyor belts further includes a timing module, which is mounted on the fixing member 520 and electrically connected to the photoelectric sensor module 410 and the stone removal module 200 respectively.

[0061] Specifically, by setting a timing module, the lifting module 100 can drive the cleaning module 200 to remove the foreign object after a preset time (the time it takes for the foreign object to move from the detection area to the cleaning area) after detecting the foreign object. Preferably, when the foreign object moves to the cleaning area, the timing module can control the conveyor belt 510 to stop for a period of time to facilitate the cleaning module 200 in removing the foreign object.

[0062] In some embodiments, such as Figure 1 , Figure 2 As shown, the clearing module 200 includes: a linear module 210, which is disposed on the fixing member 520;

[0063] The pusher 220 is mounted on the linear module 210 and is driven by the linear module 210 to move along the Y-axis in the cleaning area.

[0064] Specifically, once the foreign object moves to the removal area, the pusher 220 can be driven by the linear module 210 to move the foreign object out of the conveyor belt 510 along the Y-axis direction.

[0065] The pusher 220 includes several pusher spikes 221, and the distance between any two adjacent pusher spikes 221 is no greater than a preset width L. This allows for better pushing out of foreign objects and prevents them from passing through the gap between two adjacent pusher spikes 221.

[0066] In some embodiments, such as Figure 1 , Figure 2 As shown, the linear module 210 is a cylinder, and several pusher nails 221 are spaced apart along the Y-axis.

[0067] In some embodiments, such as Figure 1 As shown, the automatic stone removal device for the continuous ball conveyor belt also includes a collection trough 300, which is spaced apart from the conveyor belt 510. The collection trough 300 is used to collect foreign objects removed by the removal module 200.

[0068] In actual use, the pusher 220 can move foreign objects out of the conveyor belt 510 along the Y-axis direction, and the collection trough 300 can catch the foreign objects for collection.

[0069] In summary, an automatic stone removal device for a continuous ball conveyor belt is provided, comprising a lifting module and a removal module. The lifting module is mounted on a fixed component and is used to lift and deflect foreign objects conveyed to the detection area on the conveyor belt. The width of the foreign object in the Y-axis direction is greater than a preset width. The detection area is located on the conveyor belt. The removal module is mounted on the fixed component and is used to remove foreign objects from the conveyor belt within the removal area, which is located in the X-axis direction of the detection area. This invention, by setting the lifting module, detects stones in the mud and sand material in the detection area of ​​the conveyor belt. Before use, a preset width can be set to ensure that the stones do not easily clog the feed inlet of the individual continuous balls. When the width of the stone is greater than the preset width and the stone reaches the removal area, the stone can be removed by the removal module, preventing the feed inlet of the individual continuous balls from being blocked and improving production efficiency.

[0070] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
