[0044] This embodiment provides a material conveying device, such as Figure 1 As shown, the material conveying equipment includes a first transmission shaft 11, a second transmission shaft 12, a support device 2 and a coupling device 1. Specifically, the two ends of the second transmission shaft 12 are a first end 121 and a second end 122, wherein the first end 121 is used to cooperate with the coupling device 1 and the first transmission shaft 11, and the second end 122 is used to connect with the support device 2. The support device 2 is used to support the second transmission shaft 12 and enable the second transmission shaft 12 to rotate relative to the support device 2 to achieve the purpose of conveying materials. The support device 2 is set at the other end of the second transmission shaft 12 to improve the support effect of the second transmission shaft 12. In addition, the rotational connection between the support device 2 and the second transmission shaft 12 can also cooperate with the coupling device 1 to realize the rotational feeding of the second transmission shaft 12, thereby ensuring the progress of the material conveying operation.

[0045] Specifically, Figure 2As shown, the support device 2 includes a support seat 21 and a bearing 22 disposed inside the support seat 21. The bearing 22 is sleeved on the end of the second transmission shaft 12 that is not equipped with the coupling device 1, and the bearing 22 is used to be rotatably connected to the second transmission shaft 12. The bearing 22 has the advantages of compact structure and easy disassembly. Therefore, the bearing 22 is used to realize the rotatable connection of the second transmission shaft 12. At the same time, the bearing 22 cooperates with the support seat 21 to realize the support of the second transmission shaft 12, thereby ensuring the stability of the material conveying equipment.

[0046] Specifically, since each ring of the deep groove ball bearing 22 has a continuous groove raceway with a cross-section of approximately one-third of the equatorial circumference of the rolling body, and the deep groove ball bearing 22 can be used not only to bear radial loads, but also to bear certain axial loads, it has a certain breadth and applicability. In actual operation, when the radial clearance of the bearing 22 increases, the deep groove ball bearing 22 can withstand axial loads alternating in two directions, and to a certain extent has the properties of the angular contact ball bearing 22. In addition, the deep groove ball bearing 22 has the advantages of a small friction coefficient, a high limiting speed and high precision. Therefore, the above-mentioned bearing 22 can use a deep groove ball bearing 22, or other bearings 22 can be selected according to actual working conditions. This embodiment does not limit this.

[0047] Furthermore, if Figure 2 As shown, the support device 2 further includes a retaining ring 23 , wherein the retaining ring 23 is clamped on the support seat 21 and abuts against an end of the bearing 22 away from the second transmission shaft 12 , so as to limit the bearing 22 .

[0048] This embodiment also provides a coupling device 1, such as Figure 3 and Figure 4As shown, the coupling device 1 includes a first transmission shaft 11, a second transmission shaft 12, a connecting portion 13, a sliding portion 14, a locking portion 15, a first limiting portion 131 and a second limiting portion 141, wherein the second transmission shaft 12 is arranged opposite to the first transmission shaft 11 along a first direction, and the first direction is parallel to the axial direction of the first transmission shaft 11; the connecting portion 13 is detachably connected to the first transmission shaft 11 and / or the second transmission shaft 12; the sliding portion 14 is slidably sleeved on the connecting portion 13; the locking portion 15 is penetrated through the connecting portion 13 along the second direction, and the second direction is parallel to the first transmission shaft 11. The first limiting part 131 is arranged on the first transmission shaft 11 or the second transmission shaft 12; the second limiting part 141 is arranged on the sliding part 14; the coupling device 1 includes a first working state and a second working state. In the first working state, the locking part 15 abuts against the first limiting part 131 and the second limiting part 141, so that the first transmission shaft 11 and the second transmission shaft 12 are locked; in the second working state, the locking part 15 is separated from the first limiting part 131 and / or the second limiting part 141, so that the first transmission shaft 11 and the second transmission shaft 12 are unlocked. The locking part 15 is driven by the sliding part 14 to realize the locking and unlocking of the first transmission shaft 11 and the second transmission shaft 12, thereby realizing the disassembly and installation of the coupling device 1. The above-mentioned design structure is simple, and can be installed and disassembled without tools, which effectively improves the production efficiency.

[0049] Specifically, the first working state is a locked state, and the second working state is an unlocked state.

[0050] Furthermore, if Figure 3 and Figure 4 As shown, the coupling device 1 further includes a reset member 16, which is sleeved on the outer side of the second transmission shaft 12, and the two ends of the reset member 16 abut against the sliding portion 14, for resetting the sliding portion 14. By sleeved the reset member 16 on the outer side of the second transmission shaft 12, and making the two ends of the reset member 16 abut against the sliding portion 14 and the second transmission shaft 12 respectively, when disassembly and assembly are completed, the sliding portion 14 can be reset under the action of the reset member 16, and prepare for the next disassembly and assembly.

[0051] In this embodiment, since the spring has the characteristic of strong reset ability, the reset member 16 is set as a compression spring. Specifically, according to the material classification, the compression spring can be a leaf spring and a rubber spring, wherein the leaf spring has a guiding function, and due to the friction between the spring leaves, it can play a certain vibration reduction role; the rubber spring is made of rubber, generally, in order to increase the spring stroke, it is often made into a hollow shape, so the rubber spring has the advantages of sound insulation, noiseless operation, no need for lubrication and variable stiffness; according to the shape classification, the compression spring can be divided into a spiral spring and annular spring, wherein the spiral spring has the advantages of no need for lubrication, small required longitudinal space and small mass; the annular spring is a strong spring with great buffering and shock absorption ability, and is mostly used in occasions where space is limited and strong buffering is required. Therefore, the corresponding spring can be selected as the reset member 16 of this embodiment according to the actual situation, and no specific limitation is made here.

[0052] Furthermore, if Figure 3 and Figure 4 As shown, the coupling device 1 further includes a stop ring 17, which is detachably connected to the second transmission shaft 12 and abuts against one end of the reset member 16. The stop ring 17 is relatively easy to disassemble and assemble, which helps to improve the overall disassembly and assembly efficiency of the coupling device 1. In addition, the stop ring 17 has the advantages of being widely used and easy to replace at any time.

[0053] Specifically, Figure 3 and Figure 4 As shown, a stepped groove is provided on the inner side of the sliding portion 14, and the above-mentioned restoring member 16 is arranged in the stepped groove.

[0054] Specifically, the connecting portion 13 is provided with a first limiting portion 131, and the locking portion 15 can extend into the first limiting portion 131 in the first working state to lock the first transmission shaft 11 and the second transmission shaft 12. By providing the first limiting portion 131 on the connecting portion 13, it is convenient for the locking portion 15 to extend therein, thereby achieving the purpose of locking the first transmission shaft 11 and the second transmission shaft 12.

[0055] Furthermore, if Figure 3 and Figure 4 As shown, the sliding portion 14 includes an avoidance groove 143, and the sliding portion 14 can slide relative to the second transmission shaft 12 to make the locking portion 15 disengage from the first limiting portion 131 and enter the second working state. The avoidance groove 143 on the sliding portion 14 cooperates with the first limiting portion 131, so that the locking portion 15 is more easily disengaged from the first limiting portion 131, thereby making it easier to unlock the second transmission shaft 12, thereby improving the disassembly and assembly efficiency of the coupling device 1.

[0056] Furthermore, if Figure 3 and Figure 4As shown, the sliding portion 14 further includes a boss 142, which is used to abut the locking portion 15, so that the locking portion 15 is clamped on the first limiting portion 131 and enters the first working state. By arranging the boss 142 on the inner side of the sliding portion 14 and abutting the boss 142 on the locking portion 15, the locking portion 15 is clamped in the first limiting portion 131, thereby improving the locking effect of the locking portion 15 on the second transmission shaft 12; the plane can effectively save the manufacturing cost.

[0057] In this embodiment, the second transmission shaft 12 and the connecting portion 13 are separately arranged, wherein the connecting portion 13 is arranged at the first end 121 of the second transmission shaft 12, and plays the role of extension and transition. In addition, the connecting portion 13 can be sleeved on the outside of the first transmission shaft 11, and the first limiting portion 131 on the connecting portion 13 can be radially aligned with the first limiting portion 131 to form an accommodating space. The locking portion 15 is configured in this accommodating space, and the locking portion 15 can be pressed into the first limiting portion 131 by the boss 142 of the sliding portion 14, or detached from the first limiting portion 131 and slide into the avoidance groove 143, so as to realize the locking and unlocking of the first transmission shaft 11 and the second transmission shaft 12.

[0058] Furthermore, if Figure 3 and Figure 4 As shown, the coupling device 1 further includes a connecting member 18, which is disposed on the first transmission shaft 11 and is detachably connected to the second transmission shaft 12. The connecting member 18 can be attached to the inner side of the connecting portion 13 to connect the connecting portion 13 to the first transmission shaft 11. The connecting portion 13 is connected to the first transmission shaft 11 by arranging the connecting member 18, thereby improving the connection effect. At the same time, the connecting member 18 is configured as a detachable connection, which facilitates the replacement of the connecting member 18, and further improves the disassembly and installation efficiency of the coupling device 1.

[0059] In this embodiment, the connecting member 18 is configured as a flat key, and a keyway is correspondingly provided on the inner side of the connecting portion 13, and the position of the keyway is staggered with the first limiting portion 131 in the axial direction. Specifically, the ordinary flat key is used for static connection between the hub and the shaft without relative sliding. The key end shape is different and is divided into three types: round head flat key, square head flat key and single round head flat key. Among them, the keyway on the shaft of the round head flat key is milled out with a finger milling cutter on a vertical milling machine, and the shape of the groove is the same as that of the key. The key is well fixed in the groove and does not loosen during operation, but the stress concentration at the end of the keyway on the shaft is relatively large; the keyway on the shaft of the square head flat key is processed with a disc milling cutter on a horizontal milling machine, and the stress concentration of the shaft is relatively small, but the square head flat key is easy to loosen in the shaft groove. Therefore, for a larger square head flat key, a set screw is generally used to press the square head flat key to the bottom of the shaft groove to improve the overall stability; the single round head flat key is often used for the connection of the shaft end. Therefore, in the actual operation process, the selection can be made according to the actual operation situation, and no specific limitation is made here.

[0060] Specifically, Figure 3 and Figure 4 As shown, the locking portion 15 is spherical. The advantage of the spherical structure is that it has good freedom and can adapt to different installation occasions. In addition, the ball head structure also has high rigidity and impact resistance, making the coupling device 1 more stable and reliable during disassembly and installation.

[0061] Specifically, Figure 3 and Figure 4 As shown, the first limiting portion 131 is an arc groove. By setting the first limiting portion 131 as an arc groove, the spherical locking portion 15 can enter the first limiting portion 131 more easily, so that the locking portion 15 and the connecting portion 13 are more convenient to install or remove.

[0062] Optionally, one of the first limiting portion 131 and the second limiting portion 141 is a groove-shaped structure, and the other is a plane or a protrusion, and the locking portion 15 can be a spherical structure with an elastic member so that the locking portion 15 is pressed into the groove-shaped structure, thereby completing the locking of the first transmission shaft 11 and the second transmission shaft 12.

[0063] Preferably, the avoidance groove 143 is in the shape of a flat groove. Since the locking portion 15 only needs to slide into the avoidance groove 143 to unlock, and the flat groove is easier to process, the avoidance groove 143 is configured as a flat groove. In other embodiments, the avoidance groove 143 can also be in the shape of a semicircular groove, an arc groove, etc., which is not specifically limited here.

[0064] Optionally, the connecting portion 13 may be a separate part, or may be a part of the first transmission shaft 11 or the second transmission shaft 12 in an integrated manufacturing manner.

[0065] Optionally, one end of the connecting portion 13 may be fixedly connected to the first transmission shaft 11 or the second rotating shaft 12 , and the other end may be detachably connected to the first transmission shaft 11 or the second rotating shaft 12 , or both ends may be detachably connected to the first transmission shaft 11 or the second rotating shaft 12 .

[0066] Furthermore, if Figure 4 and Figure 5 As shown, a protrusion 132 is provided on the connecting portion 13 , and a slot is provided on the second transmission shaft 12 . The protrusion 132 can be inserted into the slot to connect the connecting portion 13 with the second transmission shaft 12 .

[0067] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here.
