[0036] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0037] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0038] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0039] Example 1

[0040] Reference Figure 1 to Figure 10 As shown, it is the first embodiment of the present invention, which provides a composite open vertical shaft impact sand making crusher, including a crusher body, and the crusher body includes a feed hopper 100 and a middle body 200.

[0041] Among them, Figure 1~Figure 3 As shown, a feed port 105 is provided at the center of the feed hopper 100. The feed hopper 100 includes an integrally connected ring body and a carrier plate. The ring body includes an annular vertical cylinder 101 and an annular flat plate 102 which are integrally connected and perpendicular to each other. The carrier plate includes a horizontal plate 103 and an angle adjustment plate 104 which are hingedly connected. The ring body supports the carrier plate and makes the horizontal plate 103 horizontal so that the material can smoothly enter the crusher.

[0042] An angle adjustment device 500 is provided between the horizontal plate 103 and the angle adjustment plate 104, which is used to adjust the position of the angle adjustment plate 104, so as to control the flow direction of the material. The angle adjustment plate 104 is driven to rotate by the angle adjustment device 500 to change the diameter of the feed port 105 to meet the needs of materials of different sizes or types. At the same time, when the material is blocked, the diameter of the feed port 105 is changed to alleviate the situation where the material is blocked at the feed port 105.

[0043] Specifically, the number of the horizontal plates 103 and the angle adjustment plates 104 is multiple groups and corresponds to each other. The multiple groups of horizontal plates 103 are assembled to form an annular plate structure and welded to the inner wall of the ring body. The multiple groups of angle adjustment plates 104 are assembled to form an annular plate structure, and a central opening is naturally formed by the splicing between the multiple groups of angle adjustment plates 104. The feed port 105 is the central opening, and the inclined surface formed between the horizontal plates 103 and the angle adjustment plates 104 allows the material to enter the sand making machine body more smoothly under the action of gravity, so as to adjust the speed and amount of the material entering the sand making machine body according to the material material, blockage condition and particle size.

[0044] Specifically, the middle body 200 is provided with an impeller 202 for accelerating and ejecting materials, and the top of the impeller 202 is provided with an impeller shield 201 for protecting the impeller 202. The center of the impeller shield 201 is provided with a feed opening in the shape of an inverted columnar cylinder. The feed opening in the shape of an inverted columnar cylinder has a larger opening. The larger upper opening makes it easier for materials to enter the crusher, reduces blockage during the feeding process, and ensures that the materials can smoothly enter the feed opening; secondly, the feed opening in the shape of an inverted columnar cylinder can reduce air resistance, so that during high-speed rotation, the materials are more easily sucked in. into the impeller 202, thereby improving the material introduction efficiency; secondly, the feed opening of the inverted column-shaped structure has a larger upper opening, which helps the material to be more evenly distributed around the feed opening, so that it can be better distributed when entering the crushing area, thereby improving the crushing efficiency; at the same time, the larger upper opening can accommodate more material, while the smaller lower opening can control the actual flow rate of the material, ensuring that the material can enter the crushing area at an appropriate speed, better guiding the material to fall smoothly, ensuring that the material can enter the crushing area evenly and concentratedly, and avoiding material dispersion or blockage.

[0045] The inner circumference of the middle body 200 is covered with an impact plate 203 and a lining plate 204 for protecting the inner wall of the middle body 200 and making the material accelerated and ejected by the impeller shroud 201 hit the impact plate 203 and the lining plate 204, forming a stone-beating-iron effect.

[0046] When stone hitting iron occurs in the sand making machine, it will cause high-frequency vibration of the sand making machine body, and the high-frequency vibration is transmitted to the feed hopper 100, making the discharge of the feed hopper 100 smoother. A vibrator can also be configured on the bottom wall of the feed hopper 100 to make the discharge of the feed hopper 100 smoother.

[0047] Example 2

[0048] Reference Figure 5~Figure 10As shown, it is a second embodiment of the present invention, which is based on the previous embodiment, except that a driving component 400 for adjusting the state of the angle adjustment device 500 is provided outside the angle adjustment device 500, and a linkage component 300 is externally connected to the driving component 400, and the driving component 400 is rotated to drive the linkage component 300 to move up and down to control the angle adjustment device 500 to adjust the angle between the horizontal plate 103 and the angle adjustment plate 104.

[0049] Specifically, the driving assembly 400 is used to provide the power required for the linkage assembly 300 to rotate. When the driving assembly 400 is started, the driving assembly 400 rotates and drives the linkage assembly 300 to rotate synchronously. The linkage assembly 300 converts the rotational motion into a linear motion to drive itself to move up and down to pull the angle adjustment device 500, thereby changing the angle between the horizontal plate 103 and the angle adjustment plate 104.

[0050] Reference Figure 8~Figure 10 As shown, the angle adjustment device 500 includes a support frame 510 and a rotating device 520. The support frame 510 is welded to the inner wall of the annular vertical cylinder 101 at an angle and supports the horizontal plate 103 so that the horizontal plate 103 carries materials. A rectangular through groove 511 is horizontally passed through the interior of the support frame 510. The rotating device 520 is engaged in the rectangular through groove 511 and linearly displaced under the restriction of the rectangular through groove 511.

[0051] The rotating device 520 includes a roller 521, a driving plate 522 and an outer edge gear 523. The roller 521 passes through the rectangular through slot 511 and abuts against the two sides of the outer wall of the supporting frame 510 to ensure that the roller 521 can remain stable during rotation, so that the roller 521 will not deviate during the rotation process, thereby ensuring the stability and reliability of the entire angle adjustment device 500; the number of the outer edge gears 523 is two groups, and the two groups of outer edge gears 523 are located on the rod surface of the roller 521 and close to the inner wall of the supporting frame 510. The driving plate 522 is located between the two groups of outer edge gears 523, and the rotation of the roller 521 drives the driving plate 522 to rotate synchronously to abut against the bottom surface of the angle adjustment plate 104.

[0052] Specifically, the driving plate 522 is located between the two sets of outer gears 523, and the driving plate 522 is driven to rotate synchronously by the rotation of the roller 521. When the roller 521 rotates, the outer gear 523 also rotates, and drives the driving plate 522 to rotate synchronously. The bottom surface of the driving plate 522 abuts against the bottom surface of the angle adjustment plate 104, and the rotation of the driving plate 522 pushes the angle adjustment plate 104 to adjust the angle.

[0053] Specifically, when the outer gear 523 rotates under the action of external power, the outer gear 523 drives the roller 521 to rotate synchronously, and the outer gear 523 rotates together with the roller 521. The rotation of the roller 521 drives the driving plate 522 to rotate synchronously, so that the driving plate 522 abuts against the bottom surface of the angle adjustment plate 104, thereby driving the angle adjustment plate 104 to rotate.

[0054] The angle adjustment device 500 further includes an inner traction device 530 and a rope lock block 550. The inner traction device 530 provides a driving force for the outer edge gear 523 to rotate, so as to achieve the angle adjustment of the angle adjustment plate 104. The inner traction device 530 is provided in two groups, and is respectively engaged with the two groups of outer edge gears 523. The inner traction device 530 includes a bar gear 531 engaged with the inside of the support frame 510, and a traction rope 532 and an elastic telescopic rod 533 are respectively extended from both ends of the bar gear 531. The bar gear 531 is fixed to the inner wall of the support frame 510 through the elastic telescopic rod 533, and the bar gear 531 is fixedly connected to the rope lock block 550 through the traction rope 532.

[0055] Specifically, when the angle of the angle adjustment plate 104 needs to be adjusted, the inner traction device 530 transmits the driving force through the linear displacement of the bar gear 531 .

[0056] Specifically, when the angle between the horizontal plate 103 and the angle adjustment plate 104 needs to be increased, the traction rope 532 is tightened by the rope locking block 550. The tightening of the traction rope 532 causes the bar gear 531 to move downward. During the downward movement, the bar gear 531 meshes with the outer edge gear 523, causing the outer edge gear 523 to rotate forward. The forward rotation of the outer edge gear 523 drives the driving plate 522 to rotate synchronously, thereby pushing the angle adjustment plate 104 to rotate upward, thereby increasing the angle between the horizontal plate 103 and the angle adjustment plate 104.

[0057] When the angle between the horizontal plate 103 and the angle adjustment plate 104 needs to be reduced, the traction rope 532 is loosened. At this time, the reaction force of the elastic telescopic rod 533 causes the bar gear 531 to move upward. The bar gear 531 moves upward and meshes with the outer edge gear 523, causing the outer edge gear 523 to rotate in the opposite direction. The reverse rotation of the outer edge gear 523 drives the driving plate 522 to rotate synchronously, thereby pushing the angle adjustment plate 104 to rotate downward, thereby reducing the angle between the horizontal plate 103 and the angle adjustment plate 104.

[0058] In addition, when the material rolls onto the surface of the angle adjustment plate 104, the angle adjustment plate 104 will be subjected to downward pressure, thereby generating a tendency to rotate toward the horizontal plate 103. In this case, the driving plate 522 will be subjected to pressure and have a tendency to move downward, thereby causing the roller 521 fixedly connected to the driving plate 522 to have a tendency to rotate in the reverse direction. However, due to the limiting effect of the bar gear 531 and the traction rope 532, the driving plate 522, the roller 521 and the outer edge gear 523 cannot rotate in the reverse direction.

[0059] When the material exerts pressure, the driving plate 522 is pressed and has a downward movement tendency, but due to the locking effect of the bar gear 531 and the traction rope 532, the roller 521 and the outer edge gear 523 cannot continue to rotate in the opposite direction.

[0060] The design of locking the bar gear 531 and the traction rope 532 ensures that the position of the angle adjustment plate 104 will not change easily when pressure is applied by the material, thereby maintaining the stability of the feed port 105.

[0061] Through the cooperation of the bar gear 531 and the traction rope 532, even if the pressure of the material is relatively large, the system can prevent the driving plate 522 and the outer edge gear 523 from over-rotating, thereby ensuring the stability and reliability of the system.

[0062] Reference Figure 7~Figure 9 As shown, the angle adjustment device 500 also includes a guide block 540 and an external traction device 560. The guide block 540 is fixedly connected to both sides of the inner wall of the support frame 510, and the guide block 540 is used to change the traction direction of the traction rope 532. The external traction device 560 is pressed on the surface of the rope locking block 550, and the internal traction device 530 is pulled by the rope locking block 550 to make the rotating device 520 slide inside the rectangular through groove 511.

[0063] Specifically, the guide block 540 is designed to change the traction direction of the traction rope 532 to ensure that the traction rope 532 can be fixed to the rope locking block 550. The external traction device 560 is pressed on the surface of the rope locking block 550 to pull the internal traction device 530 through the rope locking block 550.

[0064] The external traction device 560 includes an annular ring 561 and an extension rod 562 extending from the outer wall of the annular ring 561 , and a circular groove 563 for the traction rope 532 to pass through is opened on the surface of the annular ring 561 , and the extension rod 562 passes through the annular vertical cylinder 101 and is connected to the linkage assembly 300 .

[0065] Specifically, there are multiple extension rods 562 , and the multiple extension rods 562 enable each component of the annular collar 561 to move consistently during movement, thereby ensuring the stability and synchronization of the annular collar 561 when it moves up and down.

[0066] The linkage assembly 300 includes a threaded collar 301 extending outward from the outer wall of the annular vertical cylinder 101, and a worm 302 is spirally arranged inside the threaded collar 301. A ring gear 303 is suspended at the bottom end of the worm 302. The ring gear 303 is driven to rotate by an external force, so that the worm 302 rotates synchronously and drives the worm 302 to move up and down inside the threaded collar 301.

[0067] Specifically, the ring gear 303 is driven to rotate by external force, thereby causing the worm 302 to rotate synchronously and drive the worm 302 to move up and down inside the threaded collar 301. This design enables the rotation of the ring gear 303 to achieve the linear motion of the linkage assembly 300 through the up and down movement of the worm 302.

[0068] An annular double-sided gear 600 is provided between the linkage assembly 300 and the drive assembly 400. The annular double-sided gear 600 is coaxial with the feed hopper 100 and is engaged with the surface of the annular flat plate 102. The annular double-sided gear 600 is meshed with the annular gear 303. The drive assembly 400 includes a drive gear 401 and a drive motor 402. The drive gear 401 is fixed to the end of the output shaft of the drive motor 402 and is meshed with the annular double-sided gear 600.

[0069] Specifically, the annular double-sided gear 600 is in meshing transmission with the annular gear 303. The rotational motion of the control drive assembly 400 can be transmitted to the linkage assembly 300 through the annular double-sided gear 600.

[0070] Specifically, the annular double-sided gear 600 can mesh with the annular gear 303 and the driving gear 401 simultaneously to form an efficient transmission link. The center of the annular double-sided gear 600 is consistent with the central axis of the feed hopper 100, ensuring stability and synchronization during the transmission process.

[0071] The driving motor 402 provides rotational power, and transmits the power to the annular double-sided gear 600 through the driving gear 401. The rotational movement of the annular double-sided gear 600 drives the movement of the linkage assembly 300 through the meshing with the annular gear 303. This design not only improves the transmission efficiency, but also enhances the stability and reliability of the system.

[0072] Working principle: The material enters from the central feed port 105 of the feed hopper 100. The feed hopper 100 is composed of an annular vertical cylinder 101 and an annular flat plate 102. A horizontal plate 103 and an angle adjustment plate 104 are provided on the annular flat plate 102. The angle adjustment is allowed by hinged connection. An angle adjustment device 500 is provided between the horizontal plate 103 and the angle adjustment plate 104 to adjust the position of the angle adjustment plate 104, thereby controlling the flow direction of the material.

[0073] A sensor for monitoring the blockage at the feed port 105 and the flow rate of the material is provided on the sand making machine body. When the sensor detects that the material is blocked, the control system detects the blockage signal and starts the drive motor 402. The drive motor 402 drives the annular double-sided gear 600 to rotate through the drive gear 401. The rotation of the annular double-sided gear 600 is transmitted to the linkage assembly 300. The meshing of the annular gear 303 and the annular double-sided gear 600 causes the worm 302 to rotate and move in the threaded collar 301. The movement of the worm 302 is transmitted to the annular collar 561 through the extension rod 562, and the annular collar 561 releases the lock rope block 550. The lock rope block 550 moves upward or downward under the action of the elastic telescopic rod 533, and drives the bar gear 531 to move upward or downward through the elastic telescopic rod 533. While the bar gear 531 moves, it meshes with the outer edge gear 523, causing the outer edge gear 523 to rotate. The rotation of the outer gear 523 drives the driving plate 522 to rotate synchronously, thereby driving the angle adjustment plate 104 to rotate, thereby changing the diameter of the feed port 105 .

[0074] If the diameter of the feed port 105 needs to be reduced, the bar gear 531 moves downward, causing the outer edge gear 523 to rotate forward, thereby increasing the angle between the horizontal plate 103 and the angle adjustment plate 104; if the diameter of the feed port 105 needs to be increased, the bar gear 531 moves upward, causing the outer edge gear 523 to rotate reversely, thereby reducing the angle between the horizontal plate 103 and the angle adjustment plate 104.

[0075] The material flow at the feed port 105 is monitored by a sensor. If the flow is detected to be too large, the angle between the horizontal plate 103 and the angle adjustment plate 104 needs to be increased so that the angle between the horizontal plate 103 and the angle adjustment plate 104 becomes flatter, thereby slowing down the material discharge speed and reducing the aperture of the feed port 105.

[0076] If the flow rate is detected to be too small, the angle between the horizontal plate 103 and the angle adjustment plate 104 needs to be reduced so that the angle between the horizontal plate 103 and the angle adjustment plate 104 becomes steeper, thereby increasing the material discharge speed and increasing the aperture of the feed port 105.

[0077] At the same time, the sensor monitors the material flow in real time. If the flow is still too large, the above process will be repeated until the ideal flow control is achieved. If the flow returns to normal, the drive motor 402 is stopped to maintain the current position of the angle adjustment plate 104, ensuring the smoothness and controllability of the material processing process.

[0078] The present invention dynamically adjusts the size of the feed port 105 according to the blockage of the material and the flow rate through precise control of the angle adjustment device 500. The size of the feed port 105 is dynamically adjusted to ensure smooth flow of materials. Conventional crushers often use a fixed size of the feed port 105, which cannot cope with the changes in the properties of different materials. In the present invention, the position of the angle adjustment plate 104 can be fine-tuned according to actual needs to ensure that the material can be best pre-treated before entering the crushing area, thereby improving the crushing efficiency and quality.

[0079] The present invention adopts a highly efficient linkage mechanism composed of an annular double-sided gear 600, an annular gear 303, a worm 302 and a threaded collar 301, and realizes highly efficient conversion from rotational motion to linear motion. This design ensures the consistency and stability of the motion from the drive motor 402 to the angle adjustment plate 104. Traditional linkage mechanisms often have problems such as low motion conversion efficiency and uncoordinated motion, resulting in unstable operation of the equipment. However, the process of the present invention is efficient and stable, ensuring the accuracy and reliability of the equipment when adjusting the diameter of the feed port 105.

[0080] The present invention can automatically adjust the caliber of the feed port 105 according to the change of the material flow rate. The mechanism of automatically adjusting the caliber of the feed port 105 enables the device to cope with various working conditions, ensures the continuity and stability of the material processing process, improves the operating efficiency of the device, reduces the need for manual intervention, reduces the difficulty of operation, and enables the device to maintain the best working state under different working conditions.

[0081] The present invention has an anti-blocking design, and can change the diameter of the feed port 105 by adjusting the position of the angle adjustment plate 104 when the material is blocked, thereby quickly alleviating the blockage problem and ensuring the continuity of production. When a traditional crusher encounters material blockage, it often needs to be stopped for cleaning, which seriously affects the production efficiency. The present invention improves the operating efficiency of the equipment, reduces the time of downtime for cleaning, and ensures the continuity of production.

[0082] The present invention can adjust the caliber of the feed port 105, can adapt to the requirements of materials of different sizes or types, and can be used for crushing operations of various materials. Conventional crushers can often only process materials of specific sizes or types, which limits their scope of application. In the present invention, through the dynamic adjustment function of the angle adjustment plate 104, the device can adapt to the requirements of materials of different sizes or types, expand its application field, improve the flexibility of the device, and broaden its market application scope, so that the device can play an important role in different industries and fields.

[0083] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
