[0028] Referring to Figures 1-2 The utility model discloses a nut ration supply device, comprising: liftable inner box 10, fixed shell 20, power mechanism 30, discharge chute 40 and material blocking mechanism 50. Among them, liftable inner box 10 has the accommodation cavity 11 for accommodating nut, fixed shell 20 is sleeved on the outside of liftable inner box 10, and fixed shell 20 is fixed, and liftable inner box 10 is movably arranged in fixed shell 20. Power mechanism 30 is connected to liftable inner box 10, which is used for driving liftable inner box 10 to move up and down, which can be driven by manpower, or automatic linear mechanism can be used. Referring to Figures 3-4The discharge chute 40 is fixedly connected to the fixed shell 20, and has a discharge chute 41 for arranging the nuts to be discharged in the discharge chute 40. The discharge chute 41 has a feeding port and a discharge port at two ends, respectively. The discharge chute 41 is an inclined chute, and the horizontal height of the feeding port is higher than that of the discharge port, so that the nuts entering the discharge chute 41 naturally slide to the position of the discharge port under the action of gravity. The discharge port is arranged outside the accommodating cavity 11, so as to facilitate the production personnel to take out the nuts. The blocking mechanism 50 is movably arranged on the discharge port, and is used for opening or closing the discharge port.

[0029] The bagged nuts are poured into the accommodating cavity 11 of the liftable inner box 10, so that the accommodating cavity 11 is filled with the nuts. The fixed shell 20 ensures that the nuts do not overflow. The power mechanism 30 drives the liftable inner box 10 to move up and down. At this time, the discharge chute 40 is fixedly arranged. The liftable inner box 10 synchronously drives the nuts in the accommodating cavity 11 to move up and down relative to the discharge chute 40. A part of the nuts will randomly fall into the discharge chute 41. The nuts are arranged in an array under the action of the shape of the discharge chute 41, and slide along the inclined surface of the discharge chute 41 to the discharge port and are blocked by the blocking mechanism 50. When the production personnel need to take the nuts, the discharge port is opened by the blocking mechanism, the nuts are regularly discharged, and the discharge port is closed by the blocking mechanism 50 after a sufficient amount of nuts is obtained, so as to realize the function of quantitatively taking the nuts, avoid the problem that the nuts are repeatedly taken and placed due to the difficulty in quantitatively controlling the amount of the nuts to be taken, and prolong the operation time. The use is convenient, the repeated working hours are reduced, and the production efficiency is greatly improved.

[0030] Specifically, in one embodiment, the power mechanism 30 adopts a manual transmission form, and the first connecting rod 31, the second connecting rod 32, the foot pedal 33 and the rotating pivot 34 are arranged. Figures 5-6 The top end of the first connecting rod 31 is fixedly connected to the bottom of the liftable inner box 10, and the bottom end of the first connecting rod 31 is hingedly connected to the second connecting rod 32. One end of the second connecting rod 32 is hingedly connected to the first connecting rod 31, and the other end is fixedly connected to the foot pedal 33. The second connecting rod 32 abuts against the rotating pivot 34. In use, the operator steps on the foot pedal 33, the second connecting rod 32 rotates around the rotating pivot 34, drives the first connecting rod 31 to move upward, and drives the liftable inner box 10 to move upward. When the foot pedal 33 is released, the second connecting rod 32 rotates in the opposite direction around the rotating pivot 34, drives the first connecting rod 31 to move downward, and drives the liftable inner box 10 to move downward.

[0031] More specifically, referring to Figure 6 The utility model discloses a main body support 60, and the fixed shell 20 is fixed on the main body support 60. The main body support 60 provides the rotating pivot 34 for the second connecting rod 32. The second connecting rod 32 specifically abuts against the main body support 60.

[0032] Of course, as an alternative embodiment, the power mechanism 30 may also adopt an automated linear mechanism, such as a linear motor, a telescopic cylinder, and any form of linear mechanism known in the art.

[0033] Specifically, see Figure 7 The retaining structure includes a baffle 51, a pressing buckle 52, a torsion spring 53, and a fixing rod 54. The baffle 51 is rotatably mounted on the discharge port to switch between opening and closing the discharge port. The pressing buckle 52 is fixedly connected to the baffle 51. One end of the torsion spring 53 is fixed to the pressing buckle 52, and the other end abuts the discharge chute 40. The fixing rod 54 is fixed to the discharge chute 40, and the torsion spring 53 is wound around the fixing rod 54. When the discharge port needs to be opened, the pressing buckle 52 is pressed, which drives the baffle 51 to rotate, opening the discharge port and compressing the torsion spring 53. After removing the nut, the pressing buckle 52 is released, and the torsion spring 53 elastically returns to its original position, pushing the pressing buckle 52 back to its original position, causing the baffle 51 to rotate in the opposite direction, closing the discharge port.

[0034] More specifically, a boss 55 is fixed on the outer side of the discharge chute 40, and one end of the torsion spring 53 abuts against the boss 55; when the baffle 51 opens the discharge port, one end of the torsion spring 53 tightly abuts against the boss 55, so that the torsion spring 53 is in a compressed state.

[0035] Specifically, since a portion of the discharge chute 40 is located inside the liftable inner box 10, in order to avoid interference between the liftable inner box 10 and the discharge chute 40 during the lifting process, refer to FIG. Figures 3-4 A slide groove 13 is provided on the liftable inner box 10. The shape of the slide groove 13 matches the discharge chute 40. The discharge chute 40 is placed in the slide groove 13, so that the liftable inner box 10 can move up and down relative to the discharge chute 40. When the liftable inner box 10 moves up and down, the slide groove 13 slides up and down relative to the discharge chute 40 without causing interference.

[0036] More specifically, when the liftable inner box 10 is lifted to a greater height than the guide slot 13 and completely escapes the guide function of the discharge chute 40, a limit post 21 is provided on the inner side of the fixed housing 20 to maintain the guide function for the liftable inner box 10. The limit post 21 is placed in the slide slot 13 of the liftable inner box 10 and above the discharge chute 40.

[0037] Specifically, see Figures 3-4, in order to improve the probability of nut into the discharge chute 41, the bottom of the liftable inner box 10 is a circular arc bottom surface 12, the circular arc bottom surface 12 is left-right symmetrical along the two sides of the discharge groove 40, and is low in the middle and high on both sides, so that the nut in the containing cavity 11 always slides to the middle of the circular arc bottom surface 12 and is stacked on both sides of the discharge groove 40. In this way, when the liftable inner box 10 makes upward movement until the height of the nut is greater than the height of the discharge groove 40, the nut originally abutting against the two outer sides of the discharge groove 40 will lose the limiting effect of the discharge groove 40 on it, and collapse to the middle and probabilistically enter the discharge chute 41, realizing feeding.

[0038] The above embodiment is only a preferred embodiment of the present application, and cannot be used to limit the scope of protection of the present application. Any non-substantial changes and replacements made by those skilled in the art on the basis of the present application shall fall within the scope of protection of the present application.
