Description

Technical Field

[0001] The utility model relates to the technical field of sea salt weighing, and more specifically to an automatic crushing and weighing device. Background Art

[0002] Sea salt is made from seawater, which is crystallized through repeated evaporation and then harvested manually or mechanically. It has fewer processing steps and retains more of the natural minerals in the seawater. Sea salt particles vary in size and are available in different forms such as coarse salt, fine salt, and flake salt.

[0003] The production of sea salt typically involves the following steps: seawater collection, evaporation, precipitation and filtration, crystallization, stacking, and packaging. The crystallized salt is then manually stacked and left to stand to allow the water to fully dissipate. This process, known as brine infusion, can take anywhere from several months to over six months. Only after brine infusion is the salt sent to the workshop for packaging and processing.

[0004] Therefore, the sea salt needs to be crushed and weighed between stacking and packaging. In the existing technology, the sea salt is usually directly transported through a conveyor line after crushing, and quantitative packaging is carried out according to the conveying time and conveying speed. There are problems such as large differences in the weight of the packages and non-uniform particle size. Utility Model Content

[0005] The main purpose of the utility model is to provide an automatic crushing and weighing device, aiming to solve the problems of large weight differences and non-uniform particle sizes when packaging sea salt in the prior art.

[0043] The following examples will be used to describe in detail an automatic crushing and weighing device of the present application.

[0044] In this embodiment, if Figure 1 and Figure 2 As shown, the automatic crushing and weighing equipment includes: a box body 1, with a feed port on the top and a discharge port on the bottom;

[0045] Crushing mechanism 2, arranged near the feed inlet;

[0046] The filter screen 3 is arranged on the lower side of the crushing mechanism 2 and is provided with a plurality of filter holes. The box body 1 is provided with a diversion hole corresponding to the filter screen 3;

[0047] The guide plate 4 is arranged in the box body 1 and is arranged on the lower side of the filter screen 3;

[0048] The weighing mechanism 5 is provided on the lower side of the guide plate 4 and is used to receive the material guided by the guide plate 4;

[0049] The rotating mechanism 6 is disposed in the box body 1 and connected to the weighing mechanism 5 to drive the weighing mechanism 5 to rotate;

[0050] The controller (not shown) is electrically connected to the weighing mechanism 5 and the rotating mechanism 6 , respectively, and is used to control the opening and closing of the rotating mechanism 6 .

[0051] In this technical solution, the housing 1 is a rectangular cylindrical structure, extending from top to bottom. The top opening forms the feed port. A through-hole is provided on the rear side near the bottom. An inclined plate-like member is positioned at the through-hole to drain material from the weighing mechanism 5 and facilitate collection, transportation, or packaging of the crushed material from the rear. The crushing mechanism 2 is positioned near the top of the housing 1. During operation, the material to be crushed is placed onto the crushing mechanism 2 through the feed port, where it is crushed.

[0052] The filter screen 3 is positioned below the crushing mechanism 2, tilted relative to the horizontal plane. It is equipped with several evenly spaced filter holes, each with a diameter 1.2 to 1.6 times the required material particle size. The left side of the filter screen 3 is relatively low, while the right side is relatively high. A diversion hole is located on the left sidewall of the housing 1, corresponding to the upper surface of the filter screen 3. A pipe is installed on the left side of the diversion hole to guide the flow. During operation, materials that meet the required particle size flow downward through the filter holes in the filter screen 3, while materials that do not meet the particle size requirement are diverted through the diversion hole on the left, facilitating continuous input and output of the equipment.

[0053] There are two guide plates 4 that are symmetrical and inclined in the front and back. The height of the guide plate 4 near the middle is relatively low, and the height of the guide plate 4 near the front or rear is relatively high, so that the material falling from the upper side can move downward from the middle of the two guide plates 4, which is convenient for setting the weighing mechanism 5 in the middle position of the front and back to save space.

[0054] Weighing mechanism 5 is a commercially available weighing device, located below and between the two guide plates 4, to catch material falling from the upper side. A rotating mechanism 6 is a motor-driven shaft, to which weighing mechanism 5 is fixed. This rotating mechanism 6 can drive weighing mechanism 5 to rotate backward a certain angle and then return to its original position. After the rotation, the material on the rotating scale falls onto the plate-like member at the discharge port under the action of its own gravity.

[0055] The controller (not shown) is electrically connected to the weighing mechanism 5 and the rotating mechanism 6 respectively. When the weight measured by the weighing mechanism 5 reaches the set value, the controller controls the rotating mechanism 6 to rotate, and then controls the rotating mechanism 6 to reset, so as to realize the quantitative output of the material.

[0056] In this embodiment, the crushing mechanism 2 includes:

[0057] The first crushing roller 201 is a conical roller, and is rotatably arranged on the box body 1. As the diameter of the first crushing roller 201 gradually increases, the spacing between adjacent teeth gradually increases.

[0058] The second crushing roller 202 has the same structure as the first crushing roller 201 and is rotatably arranged in the box body 1 and is meshed with the first crushing roller 201;

[0059] The driving mechanism 205 is connected to the first crushing roller 201 and the second crushing roller 202, and is used to drive the first crushing roller 201 and the second crushing roller 202 to rotate towards each other.

[0060] In this technical solution, the first crushing roller 201 is rotatably mounted on the left and right sidewalls of the housing 1, with the left side lower than the right. The cone on the left end of the first crushing roller 201 has a larger diameter, while the cone on the right end has a smaller diameter. Sixteen semi-cylindrical teeth are evenly distributed around the circumference of the first crushing roller 201. The spacing between adjacent teeth on the left end, which has a larger diameter, is approximately twice the diameter of the semi-cylindrical teeth, while the spacing between adjacent teeth on the right end, which has a smaller diameter, is approximately 1.2 times the diameter of the semi-cylindrical teeth. The second crushing roller 202 is rotatably mounted behind the first crushing roller 201. The drive mechanism 205 includes a drive motor and two bevel gears, which are meshed and fixed to the first and second crushing rollers 201 and 202, respectively. The drive motor is fixedly connected to the first crushing tube.

[0061] In this embodiment, the end of the first crushing roller 201 with a smaller diameter and the end of the second crushing roller 202 with a smaller diameter are meshed with each other.

[0062] In the present technical solution, the first crushing roller 201 and the second crushing roller 202 are symmetrically arranged front to back, and the ends of the first crushing roller 201 and the second crushing roller 202 with larger diameters are both located on the left, and the ends with smaller diameters are both located on the right. This arrangement can form a porosity that gradually increases from left to right between the first crushing roller 201 and the second crushing roller 202, which is convenient for the crushing of bulk materials, the graded crushing of materials, and the direct output of materials that meet the particle size requirements.

[0063] In this embodiment, the top surfaces of the first crushing roller 201 and the second crushing roller 202 are both inclined relative to the horizontal plane.

[0064] In the present technical solution, the axes of the first crushing roller 201 and the second crushing roller 202 are both arranged in a state of being lower on the left and higher on the right, and the top surfaces of the first crushing roller 201 and the second crushing roller 202 are both arranged in a state of being lower on the left and higher on the right, so that the material can automatically move to the left on the first crushing roller 201 and the second crushing roller 202, making it easier for the material that does not meet the particle size requirements to be discharged from the guide hole.

[0065] In this embodiment, the crushing mechanism 2 further includes:

[0066] The third crushing roller 203 has the same structure as the first crushing roller 201 and meshes with the first crushing roller 201, and the end with a larger diameter of the third crushing roller 203 meshes with the end with a smaller diameter of the first crushing roller 201;

[0067] The driving mechanism 205 is connected to the third crushing roller 203 and is used to drive the third crushing roller 203 and the first crushing roller 201 to rotate in opposite directions.

[0068] In this technical solution, the third crushing roller 203 is arranged parallel to the first crushing roller 201 and is arranged in front of the first crushing roller 201. The end of the third crushing roller 203 with a larger diameter is located on the right, and the end with a smaller diameter is located on the left. The drive structure also includes two spur gears, which are respectively arranged on the first crushing roller 201 and the third crushing roller 203.

[0069] In some technical solutions, a fourth crushing roller 204 symmetrically arranged with respect to the third crushing roller 203 is further provided on the rear side of the second crushing roller 202 .

[0070] In this embodiment, it also includes:

[0071] The baffle plate 7 is provided on the upper side of the first crushing roller 201 , the second crushing roller 202 and the third crushing roller 203 .

[0072] In this technical solution, the material baffle 7 is arranged on the upper side of the left end of the first crushing roller 201, the second crushing roller 202, the third crushing roller 203 and the fourth crushing roller 204, and is used to prevent the material from falling directly downward through the left end of each crushing roller, ensuring that the material is crushed by each crushing roller.
