Description

Technical Field

[0001] This utility model belongs to the field of agricultural crop processing technology, and in particular relates to a sorting device for processing water chestnuts. Background Technology

[0002] Water chestnuts are favored by consumers for their rich nutritional content. However, the small size and flattened round shape of water chestnuts make it difficult to use existing sorting equipment for fruit selection. The common method for sorting water chestnuts at the harvest stage is manual sorting, which results in inconsistent sorting accuracy and significant mixing of fruits of different diameters, affecting the fruit's appearance and thus reducing economic benefits and farmers' income. To improve the economic value of water chestnuts, a special sorting device adapted to their unique shape is needed for fruit selection. Utility Model Content

[0003] To address the problems existing in the background technology, this utility model provides a sorting device for water chestnut processing.

Detailed Implementation

[0020] The present invention will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0021] A sorting device for water chestnut processing includes a filling hopper 1, a leveling plate 2, a conveying assembly 3, a support frame 6, and multiple sorting assemblies 4. The filling hopper 1 is fixedly mounted on the support frame 6. The leveling plate 2 is slidably mounted on the support frame 6 and connected below the discharge port of the filling hopper 1. The leveling plate 2 is inclined with the upper end higher than the lower end. The conveying assembly 3 is fixedly installed, with its upper end connected below the lower end of the leveling plate 2. The sorting assemblies 4 are fixedly installed, with their upper end connected below the lower end of the conveying assembly 3. The feeding belt 43 of the sorting assembly 4 has through-holes 46. The sorting components 4 are arranged sequentially along the feeding direction. The feeding end of each sorting component 4 is connected below the discharging end of the previous sorting component 4. The diameter of the sorting hole 46 of the subsequent sorting component 4 is larger than that of the previous sorting component 4. The water chestnuts to be sorted are filled into the filling hopper 1. The water chestnuts fall onto the equalizing plate 2 through the discharge port below the filling hopper 1. The water chestnuts slide down the inclined equalizing plate 2 onto the conveying component 3. The conveying component 3 operates to transport the water chestnuts to the sorting components 4. Multiple sorting components 4 rotate evenly to sort the water chestnuts step by step. The diameter of the water chestnuts sorted sequentially along the feeding direction increases step by step. The number of sorting components 4 is set according to the required screening accuracy of the water chestnut fruit. If high screening accuracy is required, more components are set and the difference in the diameter of the sorting holes 46 between adjacent sorting components 4 is small. If low screening accuracy is required, fewer components are set and the difference in the diameter of the sorting holes 46 between adjacent sorting components 4 is large.

[0022] The water chestnut processing sorting device also includes a drive motor 5 and a rocker arm assembly. A guide rod 62 is horizontally fixed on the support frame 6. A mounting base 21 is fixedly installed on the lower surface of the uniform material plate 2. The mounting base 21 is slidably mounted on the guide rod 62. A support plate 61 is horizontally arranged on the support frame 6 away from the uniform material plate 2. The drive motor 5 is fixedly placed on the support plate 61. The drive end of the drive motor 5 is connected to the uniform material plate 2 through the rocker arm assembly. The operation of the drive motor 5 drives the uniform material plate 2 to swing horizontally through the rocker arm assembly to screen and convey the water chestnuts.

[0023] The rocker arm assembly includes a first rocker arm 7 and a second rocker arm 8. A pin is protruding from the outer wall of the back plate of the uniform material plate 2. One end of the first rocker arm 7 is fixedly connected to the output end of the drive motor 5. One end of the second rocker arm 8 is hinged to the other end of the first rocker arm 7, and the other end of the second rocker arm 8 is hinged to the pin of the uniform material plate 2. When the drive motor 5 is running, it drives the first rocker arm 7 to rotate. The rotating rocker arm 7 pulls and drives the second rocker arm 8 to swing up and down. The rocker arm assembly as a whole performs a cyclic bending and stretching motion, thereby pushing and pulling the uniform material plate 2 to slide horizontally along the guide rod 62. That is, it drives the uniform material plate 2 to uniformly guide the water chestnuts falling from the filling hopper 1 to the conveying assembly 3 in a sieving manner.

[0024] The sorting assembly 4 includes a base frame 41, drive rollers 42, a feeding belt 43, material blocking strips 44, limiting strips 45, and a discharge plate 47. A drive roller 42 is rotatably mounted at each of the upper ends of the base frame 41. The feeding belt 43 is fitted onto the two drive rollers 42, and the feeding belt 43 is fully covered with through sorting holes 46. Multiple material blocking strips 44 are evenly spaced and protrude from the surface of the feeding belt 43, each parallel to the axis of the drive roller 42. A limiting strip 45 is provided at each end of the width direction of the feeding belt 43, and the limiting strips 45 are of the same length as the feeding belt 43. A discharge plate 47 is fixedly arranged on the base frame 41 between the two drive rollers 42. The discharge plate 47 is located in the interlayer space enclosed by the feeding belt 43 and receives the water chestnuts that leak through the sorting holes 46.

[0025] The material blocking strip 44 can effectively prevent water chestnuts from sliding backwards without being sorted when they fall from the discharge end of the conveying component 3. The two limiting strips 45 respectively block the water chestnuts at both ends of the width direction of the feeding belt 43 to prevent the water chestnuts from sliding down at both ends of the width direction without being sorted. The water chestnuts blocked by the combination of the material blocking strip 44 and the limiting strip 45 are sorted through the sorting hole 46. Water chestnuts with the correct fruit diameter fall through the sorting hole 46 onto the discharge plate 47.

[0026] The feeding plate 47 is arched upward in the middle of the width direction of the sorting component 4, that is, the surface of the feeding plate 47 is inclined downward from the middle of the width direction of the sorting component 4 to both ends. The feeding port is provided at both ends of the feeding plate 47, and the feeding port of each feeding plate 47 protrudes outside the width direction of the sorting component 4. A receiving box is movably connected below each feeding port. Baffles are erected at both ends of the feeding plate 47 in the length direction of the sorting component 4, that is, in the direction of water chestnut transportation. The baffles effectively intercept the water chestnuts to prevent them from scattering and falling, and facilitate the centralized collection of water chestnuts.

[0027] The conveying assembly 3 includes a placement frame and drive wheels, i.e., a conveyor belt. The placement frame is fixedly placed on the ground, and drive wheels are rotatably installed at both ends of the upper part of the placement frame. The conveyor belt is fitted onto the two drive wheels. A material blocking strip II is protruding from the material-carrying surface of the conveyor belt. Limiting strip II is provided on both sides of the width direction of the conveyor belt, and the limiting strip II is set to the same length as the conveyor belt.

[0028] The sorting component 4 also includes a stepper motor, the drive end of which is connected to the drive roller 42. When the stepper motor is running, the drive roller 42 rotates, thereby driving the feeding belt 43 to roll and feed the material.

[0029] The conveying assembly 3 also includes a second stepper motor. The drive end of the second stepper motor is connected to the drive wheel. When the second stepper motor is running, the drive wheel rotates, thereby driving the conveyor belt to roll and feed materials.

[0030] The filling hopper 1 is in the shape of an inverted pyramid. Two discharge ports are arranged side by side at the bottom of the filling hopper 1. The two discharge ports are arranged side by side to promote the rapid falling of the fruit. Together with the uniform material plate 2, they can promote the rapid sorting of the fruit.

[0031] Working principle: Water chestnuts are poured into the filling hopper 1 and fall onto the equalizing plate 2 from the discharge port. The equalizing plate 2 is driven by the combination of the drive motor 5 and the rocker arm assembly to slide back and forth along the guide rod 62. The equalizing plate 2 is set at an inclination. The fruit is sent to the conveying assembly 3 through the shaking screen on the equalizing plate 2. The shaking of the equalizing plate 2 can make the water chestnuts rotate naturally, which can reduce the occurrence of the water chestnuts standing upright. The conveying assembly 3 continues to operate to transport the fruit to the sorting assembly 4. The sorting assembly 4, which is set in stages, screens the fruit and collects the fruit of different diameters into different receiving boxes. The receiving box is placed below the discharge end of the last sorting assembly 4.

[0032] Because the diameter of the sorting holes 46 on the feeding belts 43 of the multiple sorting components 4 is gradually increased, fruits with smaller diameters are selected first, and fruits with larger diameters are selected last.

[0033] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
