Description

Technical Field

[0001] This utility model relates to the technical field of raw material crushing devices, and in particular to a raw material crushing device that can more thoroughly crush raw materials. Background Technology

[0002] Red dates, also known as jujubes or dates, are a common fruit and a traditional Chinese medicinal herb. They have a long history of cultivation in China and are widely used for both food and medicine. In red date production, they are often crushed. Crushing not only helps improve flavor and nutrient absorption but also facilitates processing, preservation, and transportation, making it widely used in food production and health product manufacturing. Crushing equipment is used to break red dates into small pieces or powder for subsequent processing, extraction, or consumption.

[0003] Most existing crushing devices directly crush jujubes using high-speed rotating blades. This method is relatively simple, and incompletely crushed jujube pieces are inconvenient to collect and re-crush, resulting in low crushing efficiency. Therefore, those skilled in the art have provided a raw material crushing device that can crush more thoroughly to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a raw material crushing device that achieves more thorough crushing. This device uses multiple crushing structures to perform multiple crushing operations, thereby achieving a more thorough crushing effect.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A raw material crushing device for more thorough pulverization includes a casing and a No. 1 motor. Rollers are rotatably mounted on the upper part of the inner walls on both the front and rear sides of the casing. Each of the two rollers is fixedly fitted with a crushing roller.

A No. 1 bevel gear is fixedly mounted at the front end of each of the two No. 1 rotating rods. A No. 2 rotating rod is rotatably mounted on both sides of the top surface inside the casing. A No. 2 bevel gear is fixedly fitted on the upper part of each of the two No. 2 rotating rods. The two No. 1 bevel gears mesh with the two No. 2 bevel gears respectively. A No. 2 motor is fixedly mounted on the rear end of one of the rollers.

[0007] A fixed frame is fixedly installed in the middle of the inside of the casing. Fixed cylinders are fixedly fitted on both sides of the lower end of the fixed frame. The lower ends of the two No. 2 rotating rods pass through the two fixed cylinders respectively. Screws are fixedly fitted on the lower part of the two No. 2 rotating rods. A filter plate is fixedly installed in the lower part of the inside of the casing. Side frames are fixedly installed at both ends of the filter plate. A rotating shaft is fixedly installed at the output end of the No. 1 motor. Crushing blades are fixedly installed on both sides of the rotating shaft in the lower part.

[0008] Furthermore, the two transmission gears are meshed together, and a second pulley is fixedly fitted around the rear of each of the two rollers. A first pulley is fixedly fitted around the rear of each of the two first rotating rods. The two first pulleys are connected to the two second pulleys respectively via transmission belts.

[0009] Furthermore, protective shells are fixedly installed on the upper sides of both sides inside the chassis, and the two protective shells are rotatably connected to the two No. 2 rotating rods respectively.

[0010] Furthermore, a protective shell is fixedly installed around the No. 1 motor, and a fixing rod is fixedly installed at both the front and rear ends of the protective shell.

[0013] This utility model has the following beneficial effects:

[0014] This invention proposes a raw material crushing device for more thorough pulverization. The device involves pouring dried jujubes into the unit, where a crushing roller initially crushes them. The crushed jujube pieces fall into a fixed frame, where a primary motor drives high-speed pulverizing blades to further pulverize them. The pulverized jujube powder is filtered through a filter plate and collected in a collection box. Jujube fragments that are not completely pulverized and cannot be filtered by the filter plate are guided to a side frame by a auger, then transported to the top of the fixed frame and fall back into the fixed frame for further pulverization by the blades. Two secondary rotating rods connected to the auger are equipped with secondary bevel gears, and a primary rotating rod has a primary bevel gear at its front end that meshes with the two secondary bevel gears. The two primary rotating rods and the roller are connected by pulleys, allowing the secondary motor to simultaneously drive the crushing roller and the auger, resulting in greater energy efficiency. This device ensures more thorough jujube pulverization, saving labor by eliminating the need for workers to filter and re-pour incompletely pulverized jujubes, thus improving work efficiency.

[0025] Two transmission gears 22 are meshed together. Two rollers 23 are each fixedly fitted with a second pulley 21 at the rear. Two rotating rods 4 are each fixedly fitted with a first pulley 20 at the rear. The two first pulleys 20 are connected to the two second pulleys 21 by transmission belts. Protective shells 7 are fixedly installed on the upper sides of both sides inside the machine housing 1. The two protective shells 7 are rotatably connected to the two second rotating rods 8. A protective shell 15 is fixedly installed around the first motor 16. Fixed rods 19 are fixedly installed at both ends of the protective shell 15. The opposite ends of the two fixed rods 19 are fixedly connected to the inner walls of the front and rear sides of the machine housing 1. A collection box 14 is movably installed at the lower part of the machine housing 1. The front end of the collection box 14 penetrates through the machine housing 1. A feed hopper 2 is fixedly installed at the middle of the upper end of the machine housing 1. The lower end of the feed hopper 2 penetrates to the top surface inside the machine housing 1. A support frame 25 is fixedly installed at the upper rear end of the machine housing 1. The support frame 25 is fixedly connected to the second motor 24.

[0026] Specifically, by setting rollers 23, and two rollers 23 with crushing rollers 3 fixedly fitted around them, the two rollers 23 are connected to and meshed with transmission gears 22, so that the two crushing rollers 3 can move in opposite directions, thereby crushing the dried red dates for initial crushing, reducing the volume of the red dates and thus improving the subsequent crushing efficiency. By setting a first rotating rod 4 and a second rotating rod 8, a first bevel gear 5 is set at the front end of the first rotating rod 4, and a crushing roller 3 is fixedly fitted around the upper part of the second rotating rod 8. The second bevel gear 6, the first bevel gear 5 and the second bevel gear 6 are meshed together, and the first pulley 20 is provided at the rear end of the first rotating rod 4. The second pulley 21 is fixedly sleeved around the rear of the roller 23.

The two rollers 23 are provided with transmission gears 22 on the rear side and are meshed together, so that the two rollers 23 drive the crushing roller 3 to rotate in opposite directions.

[0027] By setting filter plate 13, which is inclined to both sides, the crushed jujube powder can be filtered. The powder that cannot be filtered can fall into the side frame 12 along the inclined slope and be driven upward by auger 10 to the upper side of fixed frame 9 for crushing again. The second motor 24 drives the rotating shaft 17 to drive the crushing blade 18 to rotate at high speed to crush the jujube.

[0028] The protective shell 7 can protect the No. 1 bevel gear 5 and the No. 2 bevel gear 6, preventing powder from affecting their transmission. The collection box 14 can collect the jujube powder. The support frame 25 can support the No. 2 motor 24. The fixing rod 19 can support the protective shell 15, which can protect the No. 1 motor 16.

[0029] Working principle: When using this device, dried jujubes are poured into the feed hopper 2, and motors 16 and 24 are started. The two crushing rollers 3 rotate in opposite directions to crush the jujubes. The crushed dried jujubes fall into the fixed frame 9. Motor 16 drives the rotating shaft 17 to drive the crushing blades 18 to rotate at high speed to crush the jujubes. The crushed jujube powder is filtered through the filter plate 13 and collected in the collection box 14. Jujube fragments that are not completely crushed and cannot be filtered by the filter plate 13 are poured into the side frame 12 through the filter plate 13 tilted to both sides. They are then transmitted to the upper side of the fixed frame 9 by the auger 10 and fall back into the fixed frame 9 to be crushed by the crushing blades 18, thus crushing the jujubes more thoroughly.
