Description

Technical Field

[0001] This application relates to the technical field of material feeding equipment for warehouse discharge machines, and in particular to a rotating material feeding cylinder mechanism for a warehouse discharge machine. Background Technology

[0002] In the field of bulk grain and material storage, such as soybeans, peanuts, rice husks, and feed, vertical silo storage is becoming increasingly widespread. Silo unloading machines are a type of bulk material unloading equipment that plays an important role in unloading bulk materials with poor gravity flow.

[0003] Hydraulic-driven warehouse unloading machines are increasingly favored due to their simple structure, good explosion-proof performance, convenient maintenance, and excellent starting performance. However, most hydraulic components need to be mounted on a rotary table to follow the system in a circular motion around a central axis. Therefore, a hydraulic rotary distributor is required to rotate with the hydraulic components and supply hydraulic oil. The hydraulic rotary distributor consists of a rotating part and a fixed part, which can rotate relative to each other and each has corresponding internal oil ports. The oil ports of the fixed part are connected to the external oil circuit to the hydraulic power station, while the oil ports of the rotating part are connected to the various hydraulic components in the circular rotation motion.

[0004] Typically, the hydraulic rotary distributor is installed at the center of rotation, completely inside the feed cylinder. Most of the time, the feed cylinder is filled with material, causing the hydraulic rotary distributor and hydraulic hose to be deeply buried in the material, making later maintenance and replacement difficult. At the same time, the hydraulic hose is subjected to the scouring of material when it leaves the hopper, causing wear and reducing its service life. Utility Model Content

[0005] To improve the ease of operation of the rotary unloading cylinder mechanism of the hopper, this application provides a rotary unloading cylinder mechanism for the hopper.

[0006] This application provides a rotary feeding cylinder mechanism for a warehouse discharge machine, which adopts the following technical solution:

[0007] A rotating discharge cylinder mechanism for a warehouse discharge machine includes a fixed cylinder, a rotating cylinder rotatably connected to the fixed cylinder, a connecting assembly mounted on the fixed cylinder, and a hydraulic rotating distributor mounted on the rotating cylinder. The rotating cylinder has a semi-cylindrical design and an open groove at the axis of the rotating cylinder. A second mounting hole is provided on the rotating cylinder, and the rotating shaft of the hydraulic rotating distributor passes through the second mounting hole and extends into the groove. The bottom of the rotating cylinder is connected to the rotating shaft of the hydraulic rotating distributor.

[0008] By adopting the above technical solution, the feeding cylinder mechanism is divided into two parts: a fixed cylinder and a rotating cylinder. The fixed cylinder is equipped with connecting components, and the rotating cylinder adopts a semi-cylindrical design. The material falls from the semi-cylindrical cylinder. An open groove is set on the central axis of the semi-cylindrical cylinder, and a second mounting hole is opened on the bottom of the fixed cylinder located at the groove. The rotating shaft of the hydraulic rotary distributor passes through the second mounting hole and is set in the groove, so that the hydraulic rotary distributor is located on the outside of the semi-cylindrical cylinder, reducing the amount of material falling on the hydraulic rotary distributor, thereby reducing the strength of the connecting components eroded by the material, enhancing the service life of the feeding cylinder mechanism, and improving the convenience of the feeding cylinder mechanism of the silo discharge machine during use.

[0009] In one specific implementation, a sealing mechanism is provided between the fixed cylinder and the rotating cylinder. The sealing mechanism includes a lower ring plate mounted on the fixed cylinder. An upper ring plate is connected to the lower ring plate. Two gaskets are provided between the upper and lower ring plates, and the two gaskets are arranged in an overlapping manner. The inner arc diameter of the two gaskets is larger than the inner arc diameter of the upper ring plate. An inner ring plate is installed at the bottom of the rotating cylinder and is located between the lower and upper ring plates. The outer arc diameter of the inner ring plate is larger than the inner arc diameter of the upper ring plate and smaller than the inner arc diameter of the gaskets.

[0010] By adopting the above technical solution, the inner ring plate is set between the upper ring plate and the lower ring plate. The upper and lower ring plates limit the movement of the inner ring plate, thereby reducing the vibration amplitude of the rotating cylinder during use. By using the inner ring plate 225 to rotate between the upper ring plate 223 and the lower ring plate 221, the mutual rotation between the rotating cylinder 31 and the fixed cylinder 21 can be achieved while ensuring the sealing effect. This ensures the smooth rotation of the rotating cylinder 31, prevents the fixed cylinder 21 from interfering with the rotating cylinder 31, and enhances the stability of the rotating cylinder during use.

[0011] In one specific implementation, a sealing ring is installed on the lower ring plate, and the sealing ring is disposed below the inner ring plate.

[0012] By adopting the above technical solution, a sealing ring is added between the inner ring plate and the lower ring plate to enhance the sealing performance between the rotating cylinder and the fixed cylinder, prevent dust raised during material transportation from spreading into the air, and also prevent the external environment of the rotating cylinder from contaminating the material.

[0013] In one specific implementation, the fixed cylinder has a through hole, and a hydraulic pipe is connected to the fixed cylinder through the through hole. The hydraulic pipe is connected to the hydraulic rotary distributor.

[0014] By adopting the above technical solution, the hydraulic pipe is passed through the fixed cylinder and connected to the hydraulic rotary distributor, so that the hydraulic oil can quickly circulate inside the hydraulic rotary distributor and quickly reach the use environment.

[0015] In one specific implementation, a protective plate is installed on the fixed cylinder, and the protective plate is disposed on both sides of the hydraulic pipe.

[0016] By adopting the above technical solution, the protective plate shields the hydraulic pipe, preventing the hydraulic pipe from being washed away by the material flowing through it, which helps to extend the service life of the hydraulic pipe.

[0017] In one specific implementation, the lower end of the fixed cylinder is connected to a chassis, and a flexible connection is provided between the chassis and the fixed cylinder.

[0018] By adopting the above technical solution, the bottom of the fixed cylinder uses a flexible hose as a soft connection, which helps to reduce or compensate for the vibration generated in the working environment, prevents the vibration generated between instruments in the working environment from affecting the unloading machine and the rotating cylinder, enhances the performance of the rotating cylinder, reduces wear, and extends the service life of the rotating cylinder.

[0019] In one specific implementation scheme, a stop plate is installed on the fixed cylinder, the stop plate is disposed on the outside of the fixed cylinder, a first mounting hole is formed on the stop plate, a first limiting rod is installed on the chassis, the first limiting rod is disposed through the first mounting hole, and the first limiting rod is slidably connected to the stop plate through the first mounting hole.

[0020] By adopting the above technical solution, when the rotating cylinder is working and rotating, the first limiting rod passes through the stop ear plate to prevent the fixed cylinder from rotating, and prevents the fixed cylinder from rotating with the rotating cylinder, thereby enhancing the stability of the fixed cylinder during use.

[0021] In one specific implementation, a stop buckle is installed on the fixed cylinder, and a second limiting rod is connected to the stop buckle. The end of the second limiting rod away from the stop buckle is connected to the hydraulic rotary distributor.

[0022] By adopting the above technical solution, the second limiting rod connects the fixed cylinder to the fixed part of the hydraulic rotary distributor, keeping the fixed part at the lower end of the rotary distributor from rotating with the rotating part, thus braking the fixed part of the hydraulic rotary distributor and enhancing the stability of the hydraulic rotary distributor.

[0023] In one specific implementation scheme, a maintenance cover plate is installed on the bottom surface of the rotating cylinder, and a maintenance door is installed on the arc surface of the rotating cylinder.

[0024] By adopting the above technical solution, inspection covers and inspection doors are installed on the rotating drum, making it convenient for staff to inspect and maintain the inside of the rotating drum.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. The feeding cylinder mechanism is divided into two parts: a fixed cylinder and a rotating cylinder. A connecting component is installed on the fixed cylinder. The rotating cylinder adopts a semi-cylindrical design, and the material falls from inside the semi-cylindrical cylinder. An open groove is set on the central axis of the semi-cylindrical cylinder. A second mounting hole is opened on the bottom of the fixed cylinder located at the groove. The rotating shaft of the hydraulic rotary distributor passes through the second mounting hole and is set in the groove, so that the hydraulic rotary distributor is located on the outside of the semi-cylindrical cylinder. This reduces the amount of material falling on the hydraulic rotary distributor, thereby reducing the strength of the connecting component and enhancing the service life of the feeding cylinder mechanism. This also helps to improve the convenience of the feeding cylinder mechanism of the silo machine during use.

[0027] 2. By setting up a sealing mechanism, the inner ring plate is positioned between the upper and lower ring plates. The upper and lower ring plates limit the movement of the inner ring plate, thereby reducing the vibration amplitude of the rotating drum during use and enhancing its stability. A sealing ring is added between the inner and lower ring plates to enhance the sealing performance between the rotating drum and the fixed drum, preventing dust raised during material transportation from spreading into the air and also preventing the external environment from contaminating the material.

[0035] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0036] Example:

[0037] This application discloses a rotating feed cylinder mechanism for a warehouse discharge machine, referring to... Figure 1 and Figure 2 It includes a chassis 1, a fixed part 2 for support is fixedly installed on the chassis 1, a rotating part 3 for installation with the unloading machine is connected to the fixed part 2, and a connecting component 4 that rotates with the rotating part 3 is installed in the fixed part 2.

[0038] The feeding cylinder mechanism is divided into two parts: a rotating part 3 and a fixed part 2. The rotating part 3 is arranged on the upper side of the fixed part 2. The connecting component 4 can be installed on the inner and outer sides of the fixed part 2 to connect with the rotating part 3, which facilitates maintenance and replacement. The material is fed out by rotating the rotating part 3 in conjunction with the connecting component 4, which facilitates the rapid discharge of materials.

[0039] The fixing part 2 includes a fixing cylinder 21, which is fixedly mounted on the chassis 1. A flexible connection part 12 is provided between the fixing cylinder 21 and the chassis 1. In this embodiment, the flexible connection part 12 is made of rubber. (Refer to...) Figure 2 , Figure 4 and Figure 5The connecting component 4 includes a mounting plate 41, which is fixedly mounted on the fixed cylinder 21. A hydraulic rotary distributor 42 is located at the center of the mounting plate 41. A through-hole 211 is provided on the fixed cylinder 21, through which a hydraulic pipe 43 is installed. The hydraulic pipe 43 is connected to the oil port of the hydraulic rotary distributor 42. Two protective plates 44 are fixedly mounted on the fixed cylinder 21 to protect the hydraulic pipe 43. The two protective plates 44 are located on both sides of the hydraulic pipe 43. A stop ear plate 45 is fixedly mounted on the fixed cylinder 21 and is located on the outside of the fixed cylinder 21. A first mounting hole 451 is provided on the stop ear plate 45. A first limiting rod 46 is fixedly mounted on the chassis 1. In this embodiment, the first limiting rod 46 can also be fixedly mounted on other fixed structures located around the chassis 1 in the working environment. The first limiting rod 46 is vertically positioned through the first mounting hole 451 and is slidably connected to the stop ear plate 45 through the first mounting hole 451. In this embodiment, the upper end of the hydraulic rotary distributor 42 is a rotating shaft, and the lower end is a fixed part. The hydraulic rotary distributor 42 is existing technology, and will not be described further in this embodiment.

[0040] Reference Figure 2 and Figure 6 A stop buckle 47 for locking the hydraulic rotary distributor 42 is fixedly installed on the fixed cylinder 21. A second limit rod 48 is inserted into the stop buckle 47. The second limit rod 48 is set horizontally, and the end of the second limit rod 48 away from the stop buckle 47 is fixedly connected to the fixed part at the lower end of the hydraulic rotary distributor 42.

[0041] Hydraulic oil enters the hydraulic rotary distributor 42 through the hydraulic pipe 43 and flows inside the hydraulic rotary distributor 42. The hydraulic pipe 43 is protected by the guard plate 44 to prevent it from being washed away by materials, thus extending the service life of the hydraulic pipe 43. When the rotating shaft at the upper end of the hydraulic rotary distributor 42 rotates with the rotating part 3, the first limiting rod 46 passes through the stop ear plate 45 to fix the fixed cylinder 21 to the chassis 1, ensuring that the fixed cylinder 21 will not rotate with the rotating part 3, thus enhancing the stability of the fixed cylinder 21 during use. The second limiting rod 48 connects the fixed cylinder 21 to the hydraulic rotary distributor 42, thereby limiting the fixed part at the lower end of the hydraulic rotary distributor 42, preventing the lower fixed part of the hydraulic rotary distributor 42 from rotating with the rotating shaft during use, thus enhancing the stability of the hydraulic rotary distributor 42 during use.

[0042] Reference Figure 1 and Figure 6The rotating part 3 includes a rotating cylinder 31, the top of which is connected to the unloading machine. The rotating cylinder 31 has a semi-cylindrical design, and a semi-cylindrical open groove 311 is provided at the bottom axis of the rotating cylinder 31. The groove 311 is located at the center of the rotating cylinder 31, and a second mounting hole 312 is provided at the center of the rotating cylinder 31. The rotating shaft of the hydraulic rotating distributor 42 passes through the second mounting hole 312 and is located in the groove 311. The rotating cylinder 31 is detachably connected to the rotating shaft of the hydraulic rotating distributor 42 at the second mounting hole 312 by bolts. A maintenance cover plate 313 is detachably installed on the bottom wall of the rotating cylinder 31 by bolts. An observation window 314 is detachably installed on the vertical side wall of the rotating cylinder 31 and the maintenance cover plate 313 by bolts. A maintenance door 315 is detachably installed on the arc-shaped side wall of the rotating cylinder 31 by bolts.

[0043] The rotating drum 31 adopts a semi-cylindrical design, and the material falls from inside the semi-cylindrical drum. A semi-cylindrical open groove 311 is designed at the bottom axis of the semi-cylindrical drum, and the hydraulic rotating distributor 42 is installed on the outside of the semi-cylindrical drum to reduce the impact of the material on the hydraulic rotating distributor 42 and enhance the service life of the hydraulic rotating distributor 42. Observation windows 314 are installed on the vertical side wall of the rotating drum 31 and the inspection cover plate 313 to facilitate the staff to observe the internal condition of the rotating drum 31. The inspection door 315 and the inspection cover plate 313 can be detached and installed by bolts to facilitate the staff to carry out inspection and maintenance.

[0044] Reference Figure 2 and Figure 3 A sealing mechanism 22 is provided between the rotating cylinder 31 and the fixed cylinder 21. The sealing mechanism 22 includes a lower ring plate 221, which is fixedly installed on the fixed cylinder 21. Two washers 222 are placed on the lower ring plate 221. The two washers 222 are the same size and are arranged in an overlapping position. An upper ring plate 223 is detachably installed on the lower ring plate 221 by bolts. The two washers 222 are arranged between the lower ring plate 221 and the upper ring plate 223. The bolts pass through the two washers 222 and are fixed to the lower ring plate 221 and the upper ring plate 223 at the same time. The outer arc diameter of the two washers 222 is the same as the outer arc diameter of the lower ring plate 221 and the upper ring plate 223. The inner arc diameter of the two washers 222 is larger than the inner arc diameter of the lower ring plate 221 and the upper ring plate 223. An inner ring plate 225 is fixedly installed at the bottom of the rotating cylinder 31. The inner ring plate 225 is positioned between the upper ring plate 223 and the lower ring plate 221. The outer arc diameter of the inner ring plate 225 is larger than the inner arc diameter of the upper ring plate 223, and the outer arc diameter of the inner ring plate 225 is smaller than the inner arc diameter of the washer ring 222. The thickness of the inner ring plate 225 is the same as the thickness of one washer ring 222. A sealing ring 224 is placed on the lower ring plate 221, positioned below the inner ring plate 225. The thickness of the sealing ring 224 is the same as the thickness of one washer ring 222.

[0045] An inner ring plate 225 is installed on the rotating cylinder 31 and positioned between the upper ring plate 223 and the lower ring plate 221. The upper ring plate 223 and the lower ring plate 221 limit the movement of the inner ring plate 225, thereby reducing the vibration amplitude of the rotating cylinder 31 during use. A sealing ring 224 is added between the inner ring plate 225 and the lower ring plate 221 to enhance the sealing performance between the rotating cylinder 31 and the fixed cylinder 21, preventing dust raised during material transportation from spreading into the air and also preventing the external environment from contaminating the material. When the rotating cylinder 31 rotates, the inner ring plate 225 rotates between the upper ring plate 223 and the lower ring plate 221, ensuring the sealing effect while achieving mutual rotation between the rotating cylinder 31 and the fixed cylinder 21, ensuring the smooth rotation of the rotating cylinder 31 and preventing the fixed cylinder 21 from interfering with the rotating cylinder 31.

[0046] The implementation principle of this application embodiment is as follows: by dividing the feeding cylinder mechanism into two parts, a rotating part 3 and a fixed part 2, the rotating part 3 is arranged on the upper side of the fixed part 2, and the connecting component 4 can be installed on the inner and outer sides of the fixed part 2 to connect with the rotating part 3, which facilitates maintenance and replacement, and allows the feeding cylinder mechanism connected by rotation to deliver hydraulic oil from the fixed end to the rotating end for power transmission, so that various hydraulic actuators at the rotating end can work, which facilitates the rapid discharge of materials.

[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
