[0026] The following specific embodiments are merely explanations of the present invention and are not limitations of the present invention. After reading this specification, those skilled in the art may make modifications to the embodiments without any creative contribution as needed. However, such modifications are protected by the patent law as long as they are within the scope of the claims of the present invention.

[0027] Embodiment 1, as Figure 1-7As shown, a steering structure of a sorting device includes a slewing bearing support assembly for connecting and supporting an upper conveying device and a conveying drive shaft a passing through the slewing bearing support assembly up and down, the bottom of the slewing bearing support assembly is connected with a downwardly extending avoidance upright plate a1, the bottom of the avoidance upright plate a1 is fixedly connected with a slewing drive plate a3, the slewing drive plate a3 is provided with an axis mounting hole a4 which is opposite to the axis of the slewing bearing support assembly up and down and for the slewing drive shaft a20 of the slewing motor a2 to extend upward and be installed and connected, and an avoidance space a31 is formed between the slewing drive plate a3 and the slewing bearing support assembly. The slewing bearing support assembly is to have a slewing bearing a5 that can utilize the structure of the inner and outer rings of the slewing bearing. The outer ring of the slewing bearing can be used to be installed on the frame so that the entire structure can be installed, and the upper conveying device can be fixed with its inner ring. In this way, by driving the inner ring of the slewing bearing a5 to rotate, the upper conveying device can be turned. At the same time, the conveying drive shaft a can smoothly pass through the inner ring of the slewing bearing a5 upward to transmit the conveying power to the conveying device, so that the operation of the two will not be affected. The lower end of the conveying drive shaft a is to be connected to structures such as synchronous pulleys and synchronous belts. The avoidance space a31 can effectively provide this space. The slewing drive plate a3 is designed with an axis mounting hole a4 and the slewing drive plate a3 is connected to the slewing drive plate a3 by a shaft mounting hole a4. The rotary drive shaft a20 of the rotary motor a2 is fixedly connected, and the rotary motor a2 can adopt an existing swing motor, so that the conveying device can be driven to turn by a rotary motor. If there are other conveying devices on the frame, other conveying devices can also be designed with a rotary bearing support assembly, but there is no need for the lower side avoidance upright plate a1, rotary drive plate a3 and rotary motor a2 and other structures, because different rotary bearing support assemblies can connect the inner ring of the rotary bearing a5 in the rotary bearing assembly through a connecting rod, and by driving the inner ring of one of the rotary bearings a5, the inner rings of all the rotary bearings a5 can be driven to rotate, thereby driving the conveying device to turn.

[0028] The specific structure is as follows: the slewing bearing support assembly includes a slewing bearing a5, an upper bearing seat a51 connected to the upper part of the inner ring of the slewing bearing a5, and a lower bearing seat a52 connected to the lower part of the inner ring of the slewing bearing a5. The upper bearing seat a51 and the lower bearing seat a52 are both equipped with bearings for the conveying drive shaft a to pass through and rotate. The diameter of the inner ring of the slewing bearing a5 is larger than the diameter of the conveying drive shaft a. The slewing bearing a5 can adopt the existing slewing bearing structure type with inner and outer ring structures. The upper bearing seat a51 is used to install the conveying device on the upper side, and the lower bearing seat a52 is directly used to connect with the steering drive components such as the avoidance upright plate a1 and the rotary drive plate a3, so that the inner ring of the rotary bearing a5 can turn and drive the upper bearing seat a51 and the conveying device to turn. The inner ring and outer ring of the rotary bearing a5 can rotate relatively well, and the outer ring of the rotary bearing a5 only needs to be fixed on the frame, so the rotation of its inner ring will drive the upper conveying device to turn well. The aperture size of the inner ring of the rotary bearing a5 is to exceed the conveying drive shaft a, so that the conveying drive shaft a does not affect the power output to the conveying device. The bearings on the upper and lower bearing seats are of course for the better operation of the conveying drive shaft a, so that the steering of the conveying device and the input of power are integrated together, and the structure is compact and effective.

[0029] Preferably, the top of the avoidance upright plate a1 is fixedly connected with an annular rotary transmission plate a6 for connecting with the bottom of the lower bearing seat a52, and the annular rotary transmission plate a6 is formed with a central through hole a60 that passes through from top to bottom and allows the lower end of the conveying drive shaft a to pass downward to enter the avoidance space a31. Here, the bottom of the annular rotary transmission plate a6 connected to the lower bearing seat a52 is actually the annular bottom of the inner ring of the lower bearing seat a52, so the annular structure is more conducive to the transmission of the steering, and the central through hole a60 is also an avoidance structure, which is for the lower end of the conveying drive shaft a to extend downward for connection to a structure for power input such as a synchronous pulley. The fixing method designed in this example can adopt existing processes such as welding, screw connection or one-piece casting.

[0030] Furthermore, the plate body of the annular rotary transmission plate a6 is provided with a plurality of assembly holes a61 which penetrate vertically and surround the periphery of the central through hole a60 and are used for fixed connection with the bottom of the lower bearing seat a52. Of course, corresponding holes are provided at the bottom of the inner ring of the lower bearing seat a52 which are opposite to the assembly holes a61 vertically and can be fixed by bolts.

[0031] Preferably, the axis center of the central through hole a60 is consistent with the axis center of the shaft mounting hole a4. This preferred structure is mainly for better transmission efficiency and more reliable force.

[0032] Preferably, the outer peripheral portion of the annular rotary transmission plate a6 is integrally connected with an outer peripheral extension mounting portion a62 for fixed connection with the avoidance upright plate a1. The avoidance upright plate a1 is a flat plate, and the annular structure of the annular rotary transmission plate a6 is not very convenient for installation. The outer peripheral extension mounting portion a62 should be a block structure with a trapezoidal or rectangular device having a plane that fits the avoidance upright plate a1 in the horizontal direction, and can be installed against the plate surface of the avoidance upright plate a1, making the installation convenient and the structure more solid and stable.

[0033] Furthermore, the avoidance upright plate a1 is integrally connected to a side of the avoidance space a31 with a guide reinforcing plate a10 extending up and down. The guide reinforcing plate a10 is preferably located in the middle of the avoidance upright plate a1 to serve as a reinforcing rib and guide positioning installation.

[0034] The guide reinforcement plate a10 is in a rectangular strip structure, and the peripheral extension mounting portion a62 and the rotary drive plate a3 are provided with mounting adjustment grooves a11 which can be inserted into the guide reinforcement plate a10 and extend up and down. The mounting adjustment grooves a11 should also be rectangular, and the peripheral extension mounting portion a62 and the rotary drive plate a3 are provided on the side of the installation side to facilitate assembly and to adjust the position up and down for installation. The peripheral extension mounting portion a62 and the avoidance upright plate a1 as well as the rotary drive plate a3 and the avoidance upright plate a1 can be screwed and fixed by horizontal bolts, and screw holes can be provided at the corresponding positions.

[0035] In addition, the upper and lower bearing seats both adopt the existing annular structure, and the top outer circumference of the upper bearing seat a51 is integrally connected with a pallet plate a7 for mounting and fixing the upper conveying device, and the mounting surface is improved to improve the stability and balance of the structure. The conveying device and the pallet plate a7 can also be mounted and fixed by a locking structure such as bolts. The plate designed in this embodiment is preferably a metal plate, such as a steel plate, an aluminum alloy plate, etc.

[0036] Preferably, the upper end of the conveying drive shaft a is higher than the tray plate a7 and a magnetic drive wheel a8 is installed and connected to the upper end of the conveying drive shaft a. A magnetic wheel is also required in the middle of the corresponding conveying device to transmit power. This structure is quieter.

[0037] Embodiment 2, the attached drawings refer to embodiment 1, a belt type sorting structure, including a conveying device and a steering structure for steering the conveying device connected to the lower part of the conveying device, the conveying device includes a support frame b1, the support frame b1 is installed with two left conveying belts b21 and right conveying belts b22 distributed at intervals on the left and right, the support frame b1 is also installed with two left rollers b2 distributed front and back, two right rollers b3 distributed front and back, and a bottom tensioning roller b4 below the left rollers b2 and the right rollers b3, the two left rollers b2 and the left half of the bottom tensioning roller b4 form a left conveying belt for the left conveying belt The inverted triangle support structure around which b21 is wound, the two right rollers b3 and the right half of the bottom tensioning roller b4 form an inverted triangle support structure around which the right conveyor belt b22 is wound. The left and right conveyor belts are transported simultaneously, with better stability and fault tolerance, and more stable operation. The tensioning can be performed by adjusting the up and down position of the lower bottom tensioning roller b4. The bottom tensioning roller b4 can be installed on the support frame b1 using the existing up and down adjustable structure, so that the bottom tensioning roller b4 can be adjusted up and down and installed. The left and right rollers can also be installed in an up and down adjustable manner, or in a fixed position installation manner. Both are possible. The present embodiment is optimized in that an upper synchronous pulley b5 is fixed between the left roller b2 and the right roller b3 on the front side and between the left roller b2 and the right roller b3 on the rear side. The support frame b1 is located below the two upper synchronous pulleys b5 and is equipped with a lower synchronous pulley b6. The two upper synchronous pulleys b5 and the lower synchronous pulley b6 are arranged in an inverted triangle shape and are wound with a middle synchronous belt b7 in a triangular shape. The middle synchronous belt b7 is wound around the middle through the three synchronous pulleys in the middle of the left and right rollers for driving. The upper synchronous pulley b5 and the left and right rollers can be fixed by a key connection or a pin. The above structure enables the conveyor belt to transmit force better, has good stability, and has a low failure rate, so as to better transport goods. Among them, the design of the steering structure for steering the conveying device can adopt the steering structure of the sorting equipment used in Example 1, which has a better use effect.

[0038] Specifically, the support frame b1 is connected with a transverse rotating shaft b61 through which the lower synchronous pulley b6 passes and is fixedly connected. Of course, the support frame b1 needs to be equipped with corresponding bearings for the rotation of the transverse rotating shaft b61, and the existing structure can be used, which will not be repeated. It is mainly to fix the lower synchronous pulley b6 in a better position. Furthermore, a magnetic driven wheel b62 is also fixed on the transverse rotating shaft b61. The magnetic driven wheel b62 can be rotated by the magnetic driving structure below, thereby driving the two conveyor belts to operate through the synchronous belt.

[0039] Specifically, the steering structure has a magnetic driving wheel a8 that cooperates with the magnetic driven wheel b62. The specific design structure in Example 1 can be adopted, and the bottom of the support frame b1 is provided with an insertion hole for the magnetic driving wheel a8 to extend upward into the support frame b1 and located below the magnetic driven wheel b62, so that the power input is unobstructed.

[0040] The magnetic driving wheel a8 and the magnetic driven wheel b62 maintain a gap up and down, and are driven by magnetic attraction. The magnetic driving wheel a8 and the magnetic driven wheel b62 intersect in the axial direction to form an angle of 60-120 degrees. Preferably, the structure is designed to be vertical. The magnetic driving wheel a8 is square and the magnetic driven wheel b62 is upright. This magnetic attraction transmission structure is also one of many existing conventional designs. The magnetic selection can be any one as long as it can make the magnetic driving wheel a8 rotate and drive the magnetic driven wheel b62 to rotate.

[0041] The steering structure also has a tray plate a7, and the tray plate a7 is fixedly connected to the bottom surface of the support frame b1, and can be fixedly connected by bolts or the like.

[0042] The steering structure also has a conveying drive shaft a, and the lower end of the conveying drive shaft a is connected to a power input synchronous pulley b81. A conveying drive synchronous belt b82 is wound around the power input synchronous pulley b81. This synchronous belt design allows multiple steering structures on the frame to be wound around the same conveying drive synchronous belt b82. The lower end of the conveying drive shaft a is preferably configured with two upper and lower power input synchronous pulleys b81, one for being driven and the other for transmitting to the conveying drive shaft a of the next steering structure. If it is the last steering structure, only one power input synchronous pulley b81 can be used.

[0043] The steering structure also has a rotary motor a2, and a U-shaped frame b9 for mounting on the frame is fixed on the housing of the rotary motor a2. As mentioned in Example 1, as long as the outer ring of the rotary bearing a5 is fixed on the frame, the U-shaped frame b9 and the outer ring of the rotary bearing a5 can be mounted on the same frame plate of the frame, the outer ring of the rotary bearing a5 can be embedded and mounted on the frame plate, and the U-shaped frame b9 can be mounted on the lower side of the frame plate. Through the aforementioned steering structure, this belt-type sorting structure not only has a better conveying effect, but also a more reliable steering.

[0044] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the present invention, and these modifications or replacements should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the protection scope of the claims.
