[0050] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0051] Example 1

[0052] An automatic rice / vegetable dispensing machine, comprising:

[0053] The food lifting unit 1 comprises a running bucket 11 and a lifting mechanism 12. The running bucket 11 is detachably arranged on the lifting mechanism 12. The lifting mechanism 12 is used to realize the lifting and lowering of the running bucket 11, and the running bucket 11 is lifted to the top of the lifting mechanism 12 and then turned over to pour out the food.

[0054] The lifting mechanism 12 includes a chain transmission group, a lifting and flipping assembly 127 arranged on the chain transmission group, and a guide rail 128 for guiding the movement of the lifting and flipping assembly 127, and the operating bucket 11 is detachably mounted on the lifting and flipping assembly 127;

[0055] The chain transmission group includes two driven wheels 121, a driving wheel 122, a transmission wheel 123, a transverse transmission chain 124, a longitudinal transmission chain 125 and a chain cover 126, each of which is symmetrically arranged on both sides of the lifting and flipping assembly 127. The driven wheel 121 and the driving wheel 122 are connected by the transverse transmission chain 124, the driving wheel 122 is connected to the working motor, the driven wheel 121 and the transmission wheel 123 are connected by the longitudinal rotating chain 125, and the chain cover 126 covers the outside of the longitudinal transmission chain 125; the guide rail 128 is a 7-shaped structure including a vertical section and a horizontal section, and the guide rails 128 are two and symmetrically arranged on both sides of the lifting and flipping assembly 127, and the guide rails 128 are fixed on the chain cover 126;

[0056] The lifting and flipping assembly 127 moves along the guide rail 128 driven by the chain transmission group and realizes the rising, falling and flipping of the operating bucket 11; the lifting and flipping assembly 127 includes a first longitudinal connecting rod 1271, a second longitudinal connecting rod 1272, a third longitudinal connecting rod 1273, a fourth longitudinal connecting rod 1274, a first transverse connecting rod 1275, a second transverse connecting rod 1276, a third transverse connecting rod 1277, a fourth transverse connecting rod 1278 and a first bracket 1279; the first longitudinal connecting rod 1271, the second longitudinal connecting rod 1272, and the third longitudinal connecting rod 1273 are hinged from bottom to top, and the first longitudinal connecting rod 1271, the second longitudinal connecting rod 1272, and the third longitudinal connecting rod 1273 are all two; the two first longitudinal connecting rods 1271 are connected by the first transverse connecting rod 1275, and the first transverse connecting rod 127 The two ends of the first and second transverse connecting rods 1275 pass through the guide rails 128 on both sides and extend into the chain cover 126, and are fixedly connected to the longitudinal rotating chain 125 in the chain cover 126. The chain cover 126 is provided with a sliding groove extending longitudinally and allowing the end of the first transverse connecting rod 1275 to move up and down; the two ends of the second transverse connecting rod 1276 are respectively connected to the hinges of the second longitudinal connecting rod 1272 and the third longitudinal connecting rod 1273, that is, the second transverse connecting rod 1276 is the hinge axis of the second longitudinal connecting rod 1272 and the third longitudinal connecting rod 1273; the two third longitudinal connecting rods 1273 are connected by the third transverse connecting rod 1277, and the two ends of the third transverse connecting rod 1277 are respectively slidably arranged in the guide rails 128 on both sides; the first bracket 1279 is fixed on the third longitudinal connecting rod 1273, and the operating bucket 11 is detachably mounted on the first bracket 1279;

[0057] The fourth transverse connecting rod 1278 is located below the first transverse connecting rod 1275 and connected to the first longitudinal connecting rod 1271. The fourth transverse connecting rod 1278 can be one long rod or two short rods. The first transverse connecting rod 1275 and the fourth transverse connecting rod 1278 are also connected via the fourth longitudinal connecting rod 1274. The end of the fourth transverse connecting rod 1278 also passes through the guide rail 128 and extends into the chain cover 126, and is also fixedly connected to the longitudinal rotating chain 125 in the chain cover 126.

[0058] The bottom of the operating bucket 11 is provided with a roller 111, which can facilitate the movement of the operating bucket 11. Two opposite side walls are correspondingly provided with inserting strips 112, and a clamping block 113 is fixed below the inserting strips 112. A push handle 114 is also provided on the side wall of the operating bucket 11, and the push handle 114 facilitates the pushing of the operating bucket 11.

[0059] The first bracket 1279 is a strip-shaped rod, and the first bracket 1279 and the third longitudinal connecting rod 1273 are vertically fixedly connected to each other. A slit 12791 is provided on the side wall of the first bracket 1279 for inserting the inserting strip 112, and a fixing groove 12792 is also provided on the side wall, which is communicated with the slit 12791 and used in conjunction with the clamping block 113. The inserting strip 112 is inserted into the first bracket 1279 along the slit 12791, and the clamping block 113 is clamped in the fixing groove 12792, so as to fix the transport bucket 11.

[0060] The lifting and flipping assembly 127 rises or falls with the longitudinal rotating chain 125. Since the guide rail 128 is a 7-shaped structure including a vertical section and a horizontal section, the first longitudinal connecting rod 1271, the second longitudinal connecting rod 1272, and the third longitudinal connecting rod 1273 are hinged in sequence from bottom to top. When the lifting and flipping assembly rises to the bending part of the guide rail 128, that is, the connection part of the vertical section and the horizontal section, the two ends of the third transverse connecting rod 1277 will change from longitudinal movement to transverse movement, that is, the upper end of the third longitudinal connecting rod 1273 will change from longitudinal movement to transverse movement, and the third longitudinal connecting rod 1273 will change from longitudinal movement to transverse movement. The lower end of the connecting rod 1273 will continue to move upward under the push of the second longitudinal connecting rod 1272 and the first longitudinal connecting rod 1271 until the lower end of the third longitudinal connecting rod 1273 is higher than the upper end, so that the third longitudinal connecting rod 1273 is changed from a vertical state to a horizontal state and then to an inclined state; since the first bracket 1279 and the third longitudinal connecting rod 1273 are perpendicular to each other, the first bracket 1279 also gradually changes from the original horizontal state to a vertical state and then to an inclined state. In the inclined state, the operating bucket 11 is flipped over to pour out the rice / vegetables.

[0061] The food temporary storage unit 2 is used to temporarily hold the food / dish dumped from the running bucket 11, and comprises a hopper 21, the upper end and the lower end of the hopper 21 are both open;

[0062] The hopper 21 is provided with a stirring shaft 211, which is divided into two groups and arranged in parallel. The stirring shaft 211 includes a central axis and stirring rods radially arranged on the central axis.

[0063] The food temporary storage unit 2 also includes a dumping mechanism 22 for pushing out and dumping the hopper 21, and the dumping mechanism 22 includes a swing rod 221, a dumping cylinder 222 and a clamp 223. The lower end of the swing rod 221 is hinged on the workbench, and the upper end of the swing rod 221 is hinged on the hopper 21; a limiting groove 2211 is provided on the swing rod 221, and the clamp 223 is clamped at the limiting groove 2211. The clamp 223 is hinged to the telescopic rod of the dumping cylinder 222, and the dumping cylinder 222 is arranged horizontally and hinged on the machine bracket;

[0064] When the hopper 21 needs to be cleaned, the dumping cylinder 222 can be started to push the rocker arm 221 outward and push the hopper 21 outward. Since the dumping cylinder 222 is hinged, the positions of the clamp 223 and the rocker arm 221 are relatively fixed. When the rocker arm 221 extends outward, it will drive the hopper 21 to dump, so that the operator does not need to stand on a high place to tilt the hopper, and the operation is safe and convenient.

[0065] The dispersing unit 3 is located between the meal temporary storage unit 2 and the packaging unit 4, and is used for dispersing the meal; the dispersing unit 3 includes dispersing shafts 31 for dispersing the meal, and the dispersing shafts 31 are divided into two groups, and the two groups of dispersing shafts 31 are arranged in parallel, and the dispersing shafts 31 include a central axis and stirring rods radially arranged on the central axis.

[0066] The packing unit 4 is located below the food storage unit 2, and includes a material dispenser, a quantitative feeder 42, and a support 44. The quantitative feeder 42 is used to measure and portion the food / vegetables dropped from the food storage unit 2;

[0067] The quantitative feeder 42 includes a cylindrical rotating body 421 and a slider 422. The side wall of the rotating body 421 is provided with a rectangular through hole 4211 extending in its radial direction. The slider 422 is slidably arranged in the through hole 4211. The slider 422 is a rectangular parallelepiped structure matching the shape of the through hole 4211. The height of the slider 422 is less than the depth of the through hole 4211, so that the side wall of the through hole 4211 and the slider 422 together form an open container for containing rice / vegetables. The volume of the food contained in the quantitative feeder 42 can be changed by adjusting the size of the slider or the sliding distance of the slider in the rotating body.

[0068] The support body 44 is provided with a second mounting hole 443 which is arranged transversely for inserting the rotating body 421 and matches the shape of the rotating body 421. The rotating body 421 can rotate in the second mounting hole 443. One end of the rotating body 421 is connected to a motor driving the rotating body 421 to rotate. The upper end of the support body 44 is provided with a rice / vegetable inlet 441 which communicates with the second mounting hole 443. The lower end of the support body 44 is provided with a rice / vegetable outlet 444 which communicates with the second mounting hole 443. The rice / vegetable inlet 441 and the rice / vegetable outlet 444 are both directly opposite to the through hole 4211.

[0069] Since the slider 422 has its own gravity, the slider 422 will slide to the lower part of the through hole 4211, so that the upper part of the through hole 4211 and the top of the slider 422 form a container for holding food, and the food / dishes dropped from the hopper 21 fall into the open container surrounded by the side wall of the through hole 4211 and the slider 422 through the food / dish inlet 441, and then the rotating body 421 rotates under the drive of the motor. Since the side wall of the second mounting hole 443 has channels only at the top and bottom, when the rotating body 421 rotates at an angle of less than 180°, the side wall of the second mounting hole 443 can block the food / dishes from falling, and only when the rotating body 421 rotates 180° and the through hole 4211 is directly opposite to the food / dish outlet 444 will the food fall; and due to the influence of the slider 422's own gravity, when the rotating body 421 rotates 180°, the slider 422 will automatically fall and push the food out.

[0070] In order to ensure that the slider 422 can fall in time when the rotating body 421 rotates 180°, a pushing cylinder 43 can also be provided to push the slider 422 to move. Specifically, the slider 422 is connected with a push rod 423, and the end of the rotating body 421 is provided with an oblong hole 4212 for the push rod 423 to pass through, and the capacity of the rotating body 421 to hold food can also be adjusted by adjusting the length of the oblong hole 4212; a pushing cylinder 43 that can be telescoped in the vertical direction is provided above the push rod 423, and the pushing cylinder 43 is used to push the push rod 423 to move downward along the oblong hole 4212.

[0071] In addition, in order to increase work efficiency, two through holes 4211 can be provided on the rotating body 421, and the two through holes 4211 are arranged side by side along the axial direction of the rotating body 421, so that two lunch boxes can be filled with food at the same time.

[0072] A connector for connecting a driving motor is fixed at one end of the rotating body 421, and the connector includes a connecting disk and a connecting column vertically fixedly connected to the connecting disk. A motor connecting hole 4213 for inserting the connecting column is provided at one end of the rotating body 421, and the driving motor is connected to the connecting disk.

[0073] The pusher is located above the metering feeder 42. The pusher includes two pusher impellers 41 arranged side by side. A feeding channel is formed between the two pusher impellers 41, and the feeding channel is directly opposite to the rice / vegetable inlet 441. The pusher can slow down the falling speed of the rice and vegetables. At the same time, the two pusher impellers are arranged side by side, which plays a guiding role in the falling rice and vegetables, so that the rice and vegetables fall directly opposite to the rice / vegetable inlet 441 without spilling out.

[0074] Specifically, the pusher impeller 41 includes a rotating cylinder 411 and three blades 412, namely two U-shaped blades and one I-shaped blade. The width of the blade 412 is greater than the diameter of the rotating cylinder 411. Six uniformly distributed slot openings 4111 are formed on the side wall of the rotating cylinder 411. The three blades 412 are movably inserted into the corresponding slot openings 4111, and the I-shaped blade is clamped between the two U-shaped blades. The support body 44 is also provided with a first mounting hole 442 horizontally arranged for inserting the pusher. The first mounting hole 442 is located above the second mounting hole 443. The first mounting hole 442 has a cam-shaped contour, which is divided into a small curvature section and a large curvature section. The small curvature section is the protruding part of the cam-shaped contour, located obliquely above, and the large curvature section is located obliquely below. The side wall of the rotating cylinder 411 is attached to the large curvature section. The rotating cylinder 411 and the first mounting hole 442 are coaxial. One end of the blade 412 abuts against the side wall of the large curvature section, and the other end is pushed out to the cavity corresponding to the small curvature section, so that the blades 412 together form a cam shape that fits the shape of the first mounting hole 442. The protruding parts of the two first mounting holes 442 face each other, and the side wall openings of the first mounting holes 442 at the protruding parts are connected to the rice / vegetable inlet 441.

[0075] The blades 412 can be set to more than two groups. Specifically, they can be set to two groups. A separator 414 is provided between adjacent blades 412. The outer periphery of the separator 414 is provided with a tongue for inserting into the slot opening 4111.
