Referring to fig. 1, 2 and 3, fig. 1 is a schematic structural view of a sprocket position adjusting structure according to an embodiment of the present utility model, fig. 2 is a schematic structural view of a mounting frame of the sprocket position adjusting structure shown in fig. 1, and fig. 3 is an enlarged schematic view of a portion a in fig. 1. The sprocket position adjusting structure 100 provided in one embodiment of the present utility model includes a frame 10, a mounting frame 20, an adjusting assembly 30 and a sprocket 70, wherein the mounting frame 20 includes a fixed shaft 201, the mounting frame 20 is movably mounted on the frame 10, the sprocket 70 is mounted on the fixed shaft 201, the sprocket 70 can move along with the mounting frame 20, the adjusting assembly 30 includes a connecting rod 301 and a fastening member 302, the connecting rod 301 passes through the mounting frame 20 and is mounted on two sides of the frame 10, and the fastening member 302 is movably sleeved on the connecting rod 301 and abuts against the mounting frame 20.

The chain wheel 70 is arranged on the mounting frame 20 through the fixed shaft 201, the mounting frame 20 is movably arranged on the frame 10, and the mounting frame 20 is positioned at the tail of the fruit and vegetable sorting machine. When the position of the chain wheel 70 on the tail of the fruit and vegetable sorting machine needs to be changed, the position of the chain wheel 70 can be changed by moving the mounting frame 20 so as to change the transmission distance of the chain 60. Through such a setting, the position of the chain wheel 70 at the tail of the fruit and vegetable sorting machine can be conveniently and rapidly adjusted, and time and labor are saved.

Specifically, when it is desired to change the position of the sprocket 70, the fastener 302 moves over the connecting rod 301. After the fastener 302 moves on the connecting rod 301 from its initial position to a certain position, its final position is the final position of the fastener 302. At this time, the fastener 302 does not abut against the mounting frame 20, so that the mounting frame 20 can move on the frame 10 along the connecting rod 301, and the distance that the mounting frame 20 moves is the distance between the initial position and the final position of the fastener 302. When the mounting frame 20 is moved to a desired position, the sprocket 70 follows the mounting frame 20 to the position, and the positional adjustment of the sprocket 70 is determined according to the required transmission distance of the chain 60. At this time, the position of the fastener 302 on the connecting rod 301 is adjusted so that the fastener 302 abuts against the mount 20, and the mount 20 is fixed with respect to the frame 10. Through such a setting, can adjust the position of sprocket 70 at the tail of fruit vegetables sorter under the condition of not dismantling the tail for sprocket 70 can be adapted to the different transmission distance's of chain 60 demand, labour saving and time saving.

Regarding the sprocket 70 described above, the sprocket 70 may be fixedly connected to the fixed shaft 201, and at this time, the fixed shaft 201 is rotatably connected to the mounting frame 20; or the sprocket 70 is rotatably coupled to the fixed shaft 201, and the fixed shaft 201 is fixedly coupled to the mounting frame 20. So that the sprocket 70 can rotate, thereby realizing the transmission of the chain 60 when the chain 60 is mounted on the sprocket 70.

A plurality of sprockets 70 may be provided, the plurality of sprockets 70 being mounted side by side on the mounting frame 20, the plurality of sprockets 70 being mounted to increase the transmission path on the apparatus, thereby increasing the transmission efficiency. For example: the plurality of chain wheels 70 can be arranged at the tail of the fruit and vegetable sorting machine, and at the moment, the fruit and vegetable sorting machine is provided with a plurality of fruit and vegetable conveying channels, so that the fruit and vegetable conveying efficiency can be increased, and the fruit and vegetable sorting is facilitated to be quickened.

Regarding the above-described mounting frame 20, the mounting frame 20 may be a profile. The mounting frame 20 is connected with the sprocket 70 through the fixing shaft 201, and when the mounting frame 20 moves, the sprocket 70 can move along with the mounting frame 20. The mounting frame 20 includes a fixing member 203, and the fixing member 203 is used to fix the fixing shaft 201 on the mounting frame 20, so as to prevent the sprocket 70 from driving the fixing shaft 201 to deviate during rotation. The mounting frame 20 is preferably a rectangular frame that facilitates pushing the mounting frame 20 for movement over the frame 10.

The fixing member 203 may be a bearing housing, which is fixed to the mounting frame 20 by bolts, and the fixing shaft 201 is connected to the sprocket 70 after passing through the bearing housing. On the one hand, when the mounting frame 20 moves, the sprocket 70 can be made to follow the movement of the mounting frame 20 due to the connection of the fixed shaft 201 with the bearing housing; on the other hand, when the sprocket 70 rotates, the fixed shaft 201 is prevented from being shifted.

Regarding the above-described connection rod 301, the connection rod 301 passes through the mounting frame 20 and is mounted on both front and rear sides of the frame 10 (as viewed in fig. 1), and the connection rod 301 is fixedly connected with the frame 10. Wherein both ends of the connection rod 301 may be fixed to both sides of the frame 10 by nuts. After the connecting rods 301 are fixed to both sides of the frame 10, the mounting frame 20 can be moved between the both sides of the frame 10 to adjust the position of the mounting frame 20, so that the position of the sprocket 70 is adjusted following the mounting frame 20. The connecting rod 301 may serve as a guide during movement of the mounting frame 20, and may prevent the mounting frame 20 from being offset during movement.

Referring to fig. 4, fig. 4 is a view illustrating a use of the sprocket position adjusting structure shown in fig. 1. For example: when a longer transmission distance than before is required on the fruit and vegetable sorter, the mounting frame 20 translates backward on the frame 10, and the chain wheel 70 translates backward following the mounting frame 20 to lengthen the transmission distance of the chain 60; when it is desired to obtain a shorter travel distance on the fruit and vegetable classifier than before, the mounting frame 20 translates forward on the frame 10 and the sprocket 70 follows the forward translation of the mounting frame 20 to shorten the travel distance of the chain 60.

In some embodiments, the number of fasteners 302 is at least two, each fastener 302 abutting the mounting bracket 20. Each fastener 302, when abutted against the mounting frame 20, serves to limit movement of the mounting frame 20 on the frame 10. At this point, as sprocket 70 drives chain 60, fastener 302 may limit movement of mount 20 toward chain 60.

When there are two fasteners 302, the two fasteners 302 are respectively abutted against two sides of the mounting frame 20. With this arrangement, the fasteners 302 on both sides of the mounting frame 20 restrict movement of the mounting frame 20 along the connecting rod 301 when the mounting frame 20 is subjected to a force imparted from the sprocket 70. The number of fasteners 302 may be four. When the number of the fasteners 302 is four, two fasteners 302 are abutted against two ends of one side of the mounting frame 20, and the other two fasteners 302 are abutted against two ends of the other side of the mounting frame 20. By such an arrangement, the position of the mounting frame 20 on the frame 10 can be fixed more stably.

In some specific examples, two fasteners 302 may be moved on the connecting rod 301, when the position of the sprocket 70 at the tail needs to be adjusted, one of the fasteners 302 may be moved on the connecting rod 301 a distance to an end position, and since the two fasteners 302 abut against two sides of the mounting frame 20 in the initial position, the mounting frame 20 may adjust the position between the initial position and the end position of one of the fasteners 302, and thus the sprocket 70 may be adjusted to the desired position. The two fasteners 302 are then moved again, and the two fasteners 302 are tightened against the sides of the mounting frame 20, limiting the continued movement of the mounting frame 20 on the frame 10. With the sprocket 70 mounted on the mounting frame 20, the position of the sprocket 70 at the tail can be adjusted by this arrangement.

Specifically, when the plurality of fasteners 302 are provided, the positions of the fasteners 302 on the connecting rod 301 can be adjusted first, then, the position of the mounting frame 20 is moved until the sprocket 70 is moved to a desired position, and then, the plurality of fasteners 302 are moved toward the mounting frame 20, so that the fasteners 302 are abutted against the mounting frame 20. With this arrangement, the plurality of fasteners 302 may further secure the mounting bracket 20 to the frame 10 after the positions of the mounting bracket 20 and the sprocket 70 are adjusted.

In some embodiments, the connecting rod 301 is provided with external threads; the fastener 302 is provided with internal threads; the internal thread is matched with the external thread. The fastener 302 is screwed with the connecting rod 301. Wherein the position adjustment of the fastener 302 can be made more precise by a threaded connection. When it is desired to adjust the position of the mounting frame 20, the fastener 302 is rotated such that the fastener 302 moves over the connecting rod 301 and away from the mounting frame 20, and then the mounting frame 20 is moved to a distance that allows the sprocket 70 to accommodate the desired travel distance of the chain 60, and the fastener 302 is rotated such that the fastener 302 approaches and abuts the mounting frame 20. By the threaded connection of the fastener 302 with the connecting rod 301, on the one hand, the fastener 302 can be facilitated to abut against and be away from the mounting frame 20; on the other hand, the threaded connection may allow for more precise adjustment of the position of the mounting bracket 20 and thus the sprocket 70.

Specifically, the fastening member 302 may be a nut, and the connecting rod 301 may be a screw, and the fastening member 302 may be abutted against two sides of the mounting frame 20 through the cooperation of the screw and the nut, so as to fix the position of the mounting frame 20. When the position of the mounting frame 20 needs to be adjusted, the nut can be moved on the screw by rotating the nut, so that the mounting frame 20 can be adjusted in position within the distance.

More specifically, a plurality of nuts may be provided on the screw, and the plurality of nuts are abutted against both sides of the mounting frame 20. When a plurality of nuts are provided on the screw, the mounting frame 20 can be further fixed, and the mounting frame 20 is prevented from being driven to move when the chain 60 rotates.

Referring to fig. 5, fig. 5 is a schematic view of a portion of the sprocket position adjusting structure shown in fig. 1. In some embodiments, the sprocket position adjusting structure 100 further includes a guide assembly 40, the guide assembly 40 being mounted to the frame 10 and an outer periphery of the guide assembly 40 abutting the mounting frame 20. When the mounting frame 20 is moving, the outer circumference of the guide assembly 40 and the side surface of the mounting frame 20 abut against each other, and can be used to limit the deviation of the mounting frame 20 when moving.

Specifically, the guide assemblies 40 can abut against two ends of the mounting frame 20 to limit the positions of the front and rear ends of the mounting frame 20. When the mounting frame 20 is moving, the front and rear ends thereof are not offset, so that the whole mounting frame 20 is not offset when moving.

More specifically, the guide assembly 40 may also function as a guide for guiding movement of the mounting bracket 20 on the frame 10.

In some embodiments, the guide assembly 40 includes a connecting shaft 401 and a guide wheel 402; the connecting shaft 401 is fixedly connected with the frame 10, the guide wheel 402 is rotatably sleeved on the connecting shaft 401, and the circumferential surface of the guide wheel 402 is mutually abutted with the mounting frame 20. As the mount 20 moves over the frame 10, the guide wheels 402 begin to spin upon receiving force with the mount 20. By such arrangement, on one hand, since the guide wheel 402 and the mounting frame 20 are abutted against each other, friction force generated between the mounting frame 20 and the guide wheel 402 during movement can be reduced; on the other hand, the guide wheel 402 may act to limit the deflection of the mount 20 when rotating.

In some embodiments, the connection shaft 401 is vertically disposed.

In other embodiments, the connecting shaft 401 is rotatably connected with the frame 10, and the guide wheel 402 is fixedly arranged on the connecting shaft 401; the circumferential surface of the guide wheel 402 abuts against the mount 20. At this time, when the mounting frame 20 moves, the guide wheel 402 abuts against the mounting frame 20, and the rotation of the guide wheel 402 can be realized.

In some other examples, the connecting shaft 401 is fixedly arranged on the frame 10, and the guide wheel 402 is fixedly connected with the connecting shaft 401, and the guide wheel 402 can also play a role in guiding the mounting frame 20.

In some more specific examples, the guide wheels 402 may be provided in plural numbers, and the number of the connection shafts 401 and the number of the guide wheels 402 correspond to each other. The guide wheels 402 are mounted on the frame 10 through the connecting shafts 401, and circumferential surfaces of the guide wheels 402 are abutted against the mounting frame 20 or arranged on the running track of the mounting frame 20. Guiding the mounting frame 20 by the plurality of guide wheels 402 further ensures that no deflection occurs when the mounting frame 20 moves. For example: the guide wheels 402 can be provided with two, and two guide wheels 402 are respectively provided at both ends of the mounting frame 20, and when the mounting frame 20 is moving, the guide wheels 402 provided at both ends of the mounting frame 20 guide the mounting frame 20 to prevent the movement of the mounting frame 20 from shifting.

Referring to fig. 6 and 7, fig. 6 is a schematic view of another angle of the sprocket position adjusting structure shown in fig. 1, and fig. 7 is an enlarged schematic view of a portion B of fig. 6. In some embodiments, sprocket position adjusting structure 100 further comprises a drive assembly 50, an output end of drive assembly 50 being coupled to stationary shaft 201; the frame 10 is provided with a first strip-shaped hole 101 and a second strip-shaped hole 102, and a fixed shaft 201 is accommodated in the first strip-shaped hole 101; the driving assembly 50 includes a clamping member 501, one end of the clamping member 501 is fixedly connected with the driving assembly 50, and the other end of the clamping member 501 is received in the second bar-shaped hole 102 and is clamped with the second bar-shaped hole 102 (as shown in fig. 7).

The output end of the driving assembly 50 is fixedly connected with the fixed shaft 201, at this time, the fixed shaft 201 is rotatably connected with the mounting frame 20, the fixed shaft 201 is fixedly connected with the sprocket 70, after the driving assembly 50 is started, the output end of the driving assembly 50 drives the fixed shaft 201 to rotate, and then the fixed shaft 201 drives the sprocket 70 to rotate, so that the chain 60 mounted on the sprocket 70 can rotate through the arrangement.

With respect to the drive assembly 50 described above, the drive assembly 50 may be a commercially available drive motor. Wherein the rotational speed of the drive motor can be adjusted by changing the parameters or power of the drive motor, thereby effecting a change in rotational speed of the sprocket 70.

In some specific examples, the first bar-shaped hole 101 is configured to receive a stationary shaft 201, and the stationary shaft 201 may be coupled to an output end of the drive assembly 50 through the first bar-shaped hole 101. And the fixed shaft 201 is movable within the first bar-shaped hole 101. When it is necessary to change the position of the sprocket 70 on the tail, the mounting frame 20 moves on the frame 10, and the fixed shaft 201 and the sprocket 70 mounted on the mounting frame 20 move with the mounting frame 20. The stationary shaft 201 can now move within the first bar-shaped aperture 101 to follow the movement of the mounting frame 20. By this arrangement, synchronous movement of the mounting frame 20, the sprocket 70, the stationary shaft 201 and the drive assembly 50 can be achieved.

In some specific examples, the driving assembly 50 includes a clamping member 501, one end of the clamping member 501 is fixedly connected to the driving assembly 50, and the other end of the clamping member 501 is accommodated in the second strip-shaped hole 102 and is clamped with the second strip-shaped hole 102. When the driving assembly 50 starts to start, the driving assembly 50 can vibrate during working, and the vibration of the driving assembly 50 can be counteracted due to the fact that the other end of the clamping piece 501 is clamped with the second strip-shaped hole 102, so that the driving assembly 50 tends to be stable in operation, the fixed shaft 201 and the chain wheel 70 cannot deviate or vibrate due to vibration generated during working of the driving assembly 50, and further the chain 60 rotates stably.

Regarding the above-mentioned fastening member 501, the fastening member 501 may be made of metal, and when the fastening member 501 is made of metal, the fastening member 501 is not easy to be bent or broken due to excessive stress, and may be made of metal plate, alloy, etc.

One end of the clamping piece 501 is fixedly connected with the driving assembly 50, and specifically, a through hole can be formed in one end of the clamping piece 501, and the clamping piece 501 is fixed on the driving assembly 50 through a bolt. The other end of the clamping piece 501 is provided with an extension part 5012, the extension part 5012 of the clamping piece 501 is perpendicular to the body part 5014 of the clamping piece 501, the extension part is accommodated in the second strip-shaped hole 102, and the thickness of the extension part 5012 is the same as the width of the second strip-shaped hole 102, so that the second strip-shaped hole 102 can be just clamped with the extension part 5012 of the clamping piece 501. By such an arrangement, the vibration generated when the driving assembly 50 operates can be offset, so that the operation of the driving assembly 50 is smooth.

In some embodiments, the other end of the clamping member 501 is movable within the second bar-shaped hole 102. When it is necessary to change the position of the sprocket 70 on the tail of the fruit and vegetable sorter, the mounting frame 20 moves on the frame 10, and at this time, the fixed shaft 201 and the sprocket 70 mounted on the mounting frame 20 move following the mounting frame 20. At this time, the fixed shaft 201 moves in the first bar-shaped hole 101, so that the driving assembly 50 moves along with the fixed shaft 201, and the clamping piece 501 fixedly connected with the driving assembly 50 moves along with the driving assembly 50. At this time, the clamping member 501 moves in the second bar-shaped hole 102. By this arrangement, the synchronous movement of the driving unit 50, the engaging piece 501 and the fixed shaft 201 can be simultaneously realized.

In some specific examples, the first strip-shaped hole 101 and the second strip-shaped hole 102 formed on the frame 10 have the same direction, and the distance that the clamping piece 501 can move in the second strip-shaped hole 102 is not less than the distance that the fixing shaft 201 can move in the first strip-shaped hole 101. By this arrangement, the driving assembly 50 and the clamping member 501 can move along with the fixed shaft 201, and the driving assembly 50 and the clamping member 501 are not abutted against the end portion in the second bar-shaped hole 102 due to the fact that the moving distance of the second bar-shaped hole 102 is too small.

Referring back to fig. 5, in some embodiments, a sliding rail 103 is further provided on the frame 10, and the mounting frame 20 is slidably connected to the sliding rail 103. Wherein, the mounting frame 20 is mounted on the sliding rail 103 and matched with the sliding rail 103. The sliding rail 103 guides the movement of the mounting frame 20 when the mounting frame 20 moves on the frame 10, and prevents the mounting frame 20 from being deviated during the movement.

In some specific examples, the bottom of the mount 20 may be provided with a slider. The slider is accommodated in the slide rail 103, and moves in the slide rail 103 when the mounting frame 20 moves on the frame 10. By such an arrangement, the mount 20 can be moved on the frame 10 along the slide rail 103, and the mount 20 can be prevented from being offset when moved.

In some embodiments, the sprocket position adjusting structure 100 further includes a holding plate 104, the holding plate 104 being slidably connected to the frame 10; the supporting plate 104 corresponds to the guide assembly 40; the holding plate 104 holds the mounting frame 20 against each other. The supporting plate 104 and the guide assembly 40 are respectively arranged at two sides of the mounting frame 20, and through the arrangement, the mounting frame 20 can be further limited, and the shifting of the mounting frame 20 during moving can be prevented.

In some specific examples, the abutment plate 104 is slidably coupled to the frame 10. Make at the in-process that mounting bracket 20 removed, support and hold board 104 and can follow mounting bracket 20 and slide in frame 10, and then support and hold board 104 and support each other with mounting bracket 20 all the time, carry out spacing to mounting bracket 20 all the time, prevent the skew of mounting bracket 20.

Please refer to fig. 5 again. In some more specific examples, a chute 106 is formed on the frame 10, and the chute 106 may be a bar-shaped hole, and the distance of movement of the chute 106 is the same as the distance of movement of the mounting frame 20 on the frame 10. The supporting plate 104 is installed on the sliding groove 106 and abuts against the mounting frame 20, through the arrangement, the supporting plate 104 can slide on the frame 10 along with the mounting frame 20, and then the supporting plate 104 always supports against the mounting frame 20, and the mounting frame 20 can be prevented from shifting in the moving process.
