Description

Technical Field

[0001] This utility model relates to the field of nut grading, and in particular to a nut grading and sorting device. Background Technology

[0002] Nut grading is usually based on characteristics such as size, weight, and appearance. Different types of nuts may have different grading standards.

[0003] Chinese patent announcement number CN210098197U discloses a grading device for nut processing, including a frame, a top frame, and cylinders on both sides of the right end of the long strip of the top frame; a sorting structure is provided inside the frame; a collection bucket is provided outside the sorting structure, the collection bucket including a bucket body, and a baffle net at the top of the bucket body. This invention, by setting a multi-layered sorting structure inside the frame, allows the sorting structure to move up and down at one end and horizontally at the other end when activated, so that the nuts can both roll and vibrate on the drying net, achieving thorough sorting of nuts of different sizes, improving the sorting effect, and simultaneously screening out and collecting nut residue. In addition, a matching collection bucket with a baffle net is provided to prevent nuts from being ejected due to vibration during output, thus avoiding damage or waste, and eliminating the need for additional collection or cleaning, improving sorting efficiency and saving manpower and time.

[0004] However, this device has the following drawbacks: While it can grade nuts using the first and second grading frames, different mesh sizes of the first and second grading frames are required when grading nuts of different sizes. Furthermore, changing the first and second grading frames is cumbersome and makes it impossible to quickly adjust the grading structure for different types and sizes of nuts. To address these shortcomings, we propose a nut grading and sorting device. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a nut grading and sorting device.

[0006] To address the problems existing in the prior art, this utility model adopts the following technical solution: a nut grading and sorting device, comprising:

[0007] The main body of the equipment includes a feeding structure and a distributing structure disposed on the left side of the feeding structure;

[0008] The feeding structure includes a feeding rack, a belt conveyor installed on the inner wall of the feeding rack, and a baffle plate fixedly installed on the inner wall of the feeding rack;

[0009] The nut grading structure includes a left-side separating rack, a right-side separating rack, a separating frame rotatably mounted on the inner wall of the right-side separating rack, a separating component set inside the separating frame, and a drive component set at the upper end of the left-side separating rack to drive the separating frame to swing.

[0010] The material distribution assembly includes a support rod, a first material distribution column, a second material distribution column, and a third material distribution column that are fixedly installed on the surface of the support rod, threaded columns that are rotatably installed at both ends of the material distribution frame, and multiple nut seats that are rotatably installed on the surfaces of the two threaded columns. The two ends of the support rod are respectively hinged to the upper ends of the two nut seats. The diameters of the first, second, and third material distribution columns are all different.

[0011] The material feeding structure is located between the left and right material feeding racks and is used to guide the nuts.

[0012] Preferably, the surface of the threaded post is provided with two sections of threads rotating in opposite directions.

[0013] Preferably, the front side of the threaded post extends to the outside of the material distribution frame and is provided with a knob.

[0014] Preferably, the material dropping structure includes a material dropping plate fixedly installed on the opposite sides of the left and right material dropping frames, and two material splitting plates respectively fixedly installed on the surface of the material dropping plate.

[0015] Preferably, a baffle frame is fixedly installed at the upper end of the material distribution frame.

[0016] Preferably, the drive assembly includes a connecting shaft fixedly installed on the left end of the distribution frame, a crankshaft rotatably installed on the inner wall of the left distribution frame, a connecting rod rotatably installed on the inner wall of the crankshaft, and a motor fixedly installed on the surface of the left distribution frame for driving the crankshaft to rotate.

[0017] Preferably, the end of the connecting rod away from the crankshaft is hinged to the surface of the connecting shaft.

[0018] Preferably, a shock-absorbing spring is fixedly installed on the upper surface of the left-side material distribution frame, and the other end of the shock-absorbing spring is fixedly connected to the lower surface of the material distribution frame.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. By setting up a nut grading structure, the feeding structure can transport nuts to the sorting frame. After the nuts move into the sorting frame, they will fall through the gap between two adjacent first, second, and third sorting columns. Different gaps can be created by using first, second, and third sorting columns of different diameters, thus allowing the same type of nut to be graded into different sizes. Rotating the threaded column can drive the nut seat to move, thereby causing the nut seats to move away from or closer to each other. Therefore, the spacing between the first, second, and third sorting columns can be changed. In addition, the spacing between two adjacent first, second, and third sorting columns can be changed according to the size of different types of nuts, thus achieving the grading of different types of nuts.

[0021] 2. By setting up a drive component, when the nuts fall into the dispensing frame, the drive motor can drive the crankshaft to rotate. The rotation of the crankshaft can drive the connecting rod to pull the dispensing frame up and down and swing back and forth, thereby preventing the nuts from getting stuck in the dispensing component.

Detailed Implementation

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0031] Please see Figures 1-6 This utility model provides a technical solution: a nut grading and sorting device, comprising: a device body and a material feeding structure.

[0032] See Figure 1 The main body of the equipment includes a feeding structure and a nut grading structure located on the left side of the feeding structure.

[0033] See Figures 1-3 The feeding structure includes a feeding rack 10, a belt conveyor 11 installed on the inner wall of the feeding rack 10, and a baffle plate 12 clamped to the inner wall of the feeding rack 10 by bolts. When the nuts are poured onto the belt conveyor 11, the belt conveyor 11 can transport the nuts.

[0034] The nut grading structure includes a left-side separating rack 20, a right-side separating rack 21, a separating frame 22 rotatably mounted on the inner wall of the right-side separating rack 21, a separating component disposed inside the separating frame 22, and a driving component disposed on the upper end of the left-side separating rack 20 to drive the separating frame 22 to swing. A baffle frame 50 is fixedly installed on the upper end of the separating frame 22 to prevent the nuts inside the separating frame 22 from falling to the ground.

[0035] See Figure 3 and Figure 6 The material distribution assembly includes a support rod 30, a first material distribution column 31, a second material distribution column 32, and a third material distribution column 33 fixedly mounted on the surface of the support rod 30, threaded columns 34 rotatably mounted at both ends of the material distribution frame 22, and multiple nut seats 35 rotatably mounted on the surfaces of the two threaded columns 34. The two ends of the support rod 30 are hinged to the upper ends of the two nut seats 35 respectively. The diameters of the first material distribution column 31, the second material distribution column 32, and the third material distribution column 33 are all different.

[0036] The feeding structure can be used to transport nuts into the sorting frame 22. After the nuts move into the sorting frame 22, they will fall through the gap between two adjacent first sorting columns 31, second sorting column 32 and third sorting column 33. Different gaps can be generated by using first sorting columns 31, second sorting column 32 and third sorting column 33 with different diameters, so that the same type of nuts can be graded into different sizes.

[0037] The surface of the threaded post 34 is provided with two sections of threads rotating in opposite directions. The front of the threaded post 34 extends to the outside of the material distribution frame 22 and is provided with a knob. Rotating the knob can drive the threaded post 34 to rotate. By using the screw drive between the threaded post 34 and the nut seat 35, multiple nut seats 35 can be driven to move away from or closer to each other. Therefore, the distance between the first material distribution post 31, the second material distribution post 32 and the third material distribution post 33 can be changed. In addition, the distance between two adjacent first material distribution posts 31, second material distribution posts 32 and third material distribution posts 33 can be changed according to the size of different types of nuts to achieve grading of different types of nuts.

[0038] When the belt conveyor 11 moves the nuts to the position of the baffle plate 12, the baffle plate 12 can block excess nuts, preventing too many nuts from entering the sorting frame 22 and causing the nuts to accumulate and get stuck, affecting the quality after grading. Loosening the bolts can drive the baffle plate 12 to move on the inner wall of the feeding rack 10, so that the distance between the baffle plate 12 and the belt conveyor 11 can be adjusted according to the size of different nuts, preventing nuts that are too large from passing through.

[0039] See Figures 4-5 The drive assembly includes a connecting shaft 60 fixedly mounted on the left end of the distribution frame 22, a crankshaft 61 rotatably mounted on the inner wall of the left distribution frame 20, a connecting rod 62 rotatably mounted on the inner wall of the crankshaft 61, and a motor 63 fixedly mounted on the surface of the left distribution frame 20 for driving the crankshaft 61 to rotate. The end of the connecting rod 62 away from the crankshaft 61 is hinged to the surface of the connecting shaft 60.

[0040] A shock-absorbing spring 70 is fixedly installed on the upper surface of the left-side material distribution frame 20, and the other end of the shock-absorbing spring 70 is fixedly connected to the lower surface of the material distribution frame 22. When the nuts fall into the material distribution frame 22, the drive motor 63 can drive the crankshaft 61 to rotate. The rotation of the crankshaft 61 can drive the connecting rod 62 to pull the material distribution frame 22 to swing up and down, thereby preventing the nuts from getting stuck in the material distribution component.

[0041] See Figure 1 The feeding structure is set between the left feeding rack 20 and the right feeding rack 21 to guide the nuts. The feeding structure includes a feeding plate 40 fixedly installed on the opposite side of the left feeding rack 20 and the right feeding rack 21, and two feeding plates 41 fixedly installed on the surface of the feeding plate 40. The two feeding plates 41 can divide the feeding plate 40 into three areas, so that nuts of different sizes can fall into the three areas respectively, thereby avoiding the mixing of nuts.

[0042] Working principle:

[0043] Rotating the knob can drive the threaded column 34 to rotate. By using the screw drive between the threaded column 34 and the nut seat 35, multiple nut seats 35 can be driven to move away from or closer to each other. Therefore, the distance between the first dividing column 31, the second dividing column 32 and the third dividing column 33 can be changed. Thus, the distance between two adjacent first dividing columns 31, second dividing columns 32 and third dividing columns 33 can be changed according to the size of different kinds of nuts.

[0044] After the spacing between the first dividing column 31, the second dividing column 32 and the third dividing column 33 is adjusted, the nuts are poured onto the belt conveyor 11. The belt conveyor 11 can transport the nuts. When the belt conveyor 11 moves the nuts to the position of the baffle plate 12, the baffle plate 12 can block the excess nuts, preventing too many nuts from entering the dividing frame 22 and causing the nuts to accumulate and get stuck.

[0045] When the nuts are fed into the sorting box 22, they will fall through the gap between two adjacent first sorting columns 31, second sorting column 32 and third sorting column 33. Different gaps can be generated by using first sorting columns 31, second sorting column 32 and third sorting column 33 with different diameters, so that the same type of nuts can be graded into different sizes.

[0046] When grading nuts, the drive motor 63 can drive the crankshaft 61 to rotate. The rotation of the crankshaft 61 can drive the connecting rod 62 to pull the material distribution frame 22 to swing up and down, which can prevent nuts from getting stuck in the material distribution component.

[0047] After the nuts are graded, nuts of different sizes will fall into three separate areas, thus preventing them from getting mixed up.

[0048] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art based on the technical solution and concept of the present utility model should be included within the protection scope of the present utility model.
