Description

Technical Field

[0001] This utility model relates to the field of agricultural product processing equipment technology, and in particular to an integrated machine for crushing and grinding agricultural products. Background Technology

[0002] In the field of agricultural product processing, crushers are an indispensable key piece of equipment. They are widely used in various applications such as feed preparation, grain processing, and processing of Chinese medicinal materials. By crushing large pieces and whole granules of materials into powder or fine particles, they can meet the needs of subsequent production or use.

[0003] However, during the harvesting, drying, and transportation of agricultural products, hard impurities such as stones, mud, and metal pieces inevitably get mixed in. In existing processing procedures, if these raw materials mixed with impurities are directly fed into the crusher, the high-speed rotating blades, hammers, or toothed discs are very likely to violently collide with the hard impurities, leading to rapid wear, chipping, or even breakage of the parts. This not only severely shortens the service life of the equipment but also causes frequent downtime for maintenance, significantly increasing production and maintenance costs and reducing overall processing efficiency.

[0004] To address these issues, a common practice in existing technologies is to add a filtration or screening process before the crusher, such as using a filter screen to intercept and separate impurities from the raw materials. This improvement does indeed protect subsequent crushing equipment to some extent. However, in actual continuous production applications, especially when processing large quantities of high-humidity materials, its inherent defects gradually become apparent. Under the influence of gravity and feed thrust, materials tend to accumulate and adhere to the surface of the filter screen, gradually covering the effective sieve openings and eventually causing blockages.

[0005] Once the filter screen becomes clogged, it not only causes a sharp drop in screening efficiency, affecting the processing speed of the entire production line, but in severe cases, it can also cause material overflow or complete blockage of the front-end feed channel. Current methods typically rely on manual periodic shutdowns for cleaning. This passive manual intervention is not only inefficient and increases the labor intensity of workers, but more importantly, it disrupts the continuity of production operations, significantly reducing the automation level of the entire equipment and becoming a key technical bottleneck limiting capacity expansion.

[0006] Therefore, this utility model proposes an integrated agricultural product crushing and grinding machine to address the shortcomings of existing technologies. Utility Model Content

[0007] In view of the problems in the existing agricultural product crushing and grinding integrated machine, such as the hard impurities mixed in the raw materials easily damaging the crushing parts, and the material easily accumulating on the filter screen during continuous filtration, causing blockage and affecting production efficiency and automation level, this utility model aims to provide an agricultural product crushing and grinding integrated machine with an improved structure that can effectively solve the above problems.

[0008] This utility model provides an integrated agricultural product crushing and grinding machine, including: a fixed frame, and a crusher fixedly installed at the lower part of the fixed frame. A filter mechanism is fixedly installed on the upper part of the fixed frame, and the discharge end of the filter mechanism is connected to the feed end of the crusher; and a lifting mechanism for adjusting the working angle of the filter mechanism.

[0009] The lifting mechanism is an innovation that enables the anti-clogging function of this utility model. It is fixed to the fixed frame and is linked with the filter screen in the filtration mechanism.

[0010] Furthermore, the lifting mechanism, the filtering mechanism, and the fixed frame are combined in the following way: the lifting mechanism includes a support frame fixed to the fixed frame, and a gear is rotatably connected inside the support frame. The gear meshes with a rack that can slide vertically inside the support frame. The upper end of the rack abuts against the bottom of one side of the filter screen, thereby transmitting linear motion to the filter screen. The lifting mechanism also includes a second motor mounted on the fixed frame. The second motor serves as a power source to drive the gear to rotate. Through the transmission between the gear and the rack, the active lifting or lowering of one side of the filter screen is ultimately achieved.

[0011] Preferably, in order to effectively pre-process large pieces of agricultural products before filtration, the filtration mechanism also includes a feeding bin located above the filter screen, with cutting blades rotatably installed inside the feeding bin, and also includes a motor for driving the cutting blades to rotate, thus realizing the pre-cutting function of the material.

[0012] Preferably, in order to improve screening efficiency and promote the movement of materials on the filter screen, the filtration mechanism also includes a vibration motor for driving the filter screen to vibrate. The vibration motor is fixedly connected to the bottom of the filter screen and achieves rapid separation of agricultural products and impurities through high-frequency vibration.

[0013] Preferably, furthermore, in order to absorb and buffer the vibration generated when the above-mentioned vibration motor is working, so as to ensure the operational stability and structural reliability of the whole machine, a shock absorber is also provided between the filter screen and the fixed frame.

[0014] Preferably, in order to effectively collect the screened impurities and prevent agricultural products from scattering from both sides during the conveying process, a collection box is provided below the filter screen, and the side walls of the collection box extend upward along both sides of the filter screen, forming a structure that combines collection and containment functions.

[0015] Preferably, in order to ensure that the screened agricultural products can smoothly enter the next process, a chute is used to connect the discharge end of the filtration mechanism and the feed end of the crusher, providing a clear conveying channel for the materials.

[0016] Preferably, in order to provide a stable and reliable mounting platform for the power source of the lifting mechanism, the lifting mechanism also includes a placement plate, which is fixed on the mounting frame, and the motor is stably mounted on the placement plate.

[0017] Preferably, as a specific power transmission implementation method, a turntable is coaxially fixed on the output shaft of the second motor. The turntable is fixedly connected to the gear by a key connection or integral molding. This structure ensures that power can be transmitted from the second motor to the gear efficiently and accurately.

[0018] This utility model has the following beneficial effects: 1. This utility model, by setting up a filtration mechanism, first uses cutting blades to pre-crush agricultural products before they enter the crusher, and then uses a vibrating motor to drive the filter screen for vibration screening. This solves the problem in the prior art where hard impurities such as stones mixed in agricultural raw materials directly enter the crusher, causing equipment blockage and component damage. It achieves the beneficial effects of effectively removing impurities, protecting crushing components, significantly improving the working efficiency of the crusher, and extending the service life of the equipment. 2. This utility model, by setting up a lifting mechanism, utilizes the transmission cooperation of a motor driving gear and rack to actively lift one side of the filter screen to change its tilt angle. This solves the problem in the prior art where the filter screen is clogged due to material accumulation during long-term operation or when processing wet materials, which affects continuous production efficiency. It achieves the beneficial effects of actively removing accumulated materials, effectively preventing clogging, ensuring continuous and efficient operation of the filtration process, and enhancing the equipment's adaptability to different materials. 3. This utility model organically integrates cutting, vibration filtering, anti-clogging lifting, and crushing and grinding functions into an integrated structure, forming a top-down automated processing flow. It solves the problems of traditional agricultural product processing processes requiring multiple independent devices, large floor space, cumbersome material transfer, and low automation. It achieves the beneficial effects of compact equipment structure, comprehensive functions, high automation, reduced intermediate transfer links, and improved overall production efficiency.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0021] Example: Please refer to Figures 1 to 4 This utility model provides an integrated agricultural product crushing and grinding machine, which aims to solve the problems of existing agricultural product crushers 4, where stones and other impurities mixed in the raw materials can easily damage the crushing components, and the materials can easily accumulate on the filter screen 204 during continuous filtration, causing blockage.

[0022] like Figure 1 and Figure 2 As shown, the integrated agricultural product crushing and grinding machine includes a fixed frame 1, and a filter mechanism 2, a lifting mechanism 3, and a crusher 4 respectively installed on the fixed frame 1. The fixed frame 1 serves as the mounting base for the entire device, providing stable installation and support for the filter mechanism 2, the lifting mechanism 3, and the crusher 4. The crusher 4 is fixedly installed at the lower part of the fixed frame 1 and is used for the final crushing and grinding of the processed agricultural products. The filter mechanism 2 is fixedly installed at the upper part of the fixed frame 1, located above the crusher 4, and is used for cutting and screening pretreatment of the agricultural products before they enter the crusher 4. The discharge end of the filter mechanism 2 is connected to the feed end of the crusher 4, thus forming a top-down material processing flow path. The lifting mechanism 3 is fixed to the fixed frame 1 and forms a linkage connection with the filter mechanism 2, and is used to actively adjust the working angle of the filter mechanism 2 to prevent material blockage.

[0023] As one of the innovations of this utility model, please refer to the following: Figure 2 and Figure 4The lifting mechanism 3 is specifically constructed as follows: it includes a support frame 301 fixed to the fixed frame 1, which provides a mounting base for subsequent transmission components; a gear 304 is rotatably connected inside the support frame 301, and a rack 302 is also housed within the support frame 301. The rack 302 and gear 304 are always meshed, and the rack 302 can reciprocate vertically under the constraint of the support frame 301; the upper end of the rack 302 abuts against the filter screen 204 in the filtering mechanism 2. The bottom of one side transmits the linear motion of the rack 302 to the filter screen 204; the lifting mechanism 3 also includes a second motor 305, which is mounted on the fixed frame 1 and serves as the power source for the entire lifting mechanism 3, driving the gear 304 to rotate; when the second motor 305 rotates in the forward direction, it drives the rack 302 to move upward through the gear 304, thereby lifting one side of the filter screen 204; when the second motor 305 rotates in the reverse direction, it drives the rack 302 to descend smoothly, allowing the filter screen 204 to return to its original position.

[0024] Please refer to Figure 2 and Figure 3 The filtration mechanism 2 is the pre-processing unit of the whole machine. It is fixedly installed on the upper part of the fixed frame 1 and located directly above the crusher 4. This layout ensures that agricultural products can smoothly enter the crusher 4 from the filtration mechanism 2 for subsequent processing. The filtration mechanism 2 includes a feeding bin 203, which serves as the initial inlet for agricultural products. Inside the feeding bin 203, a cutting blade 202 is rotatably installed. The cutting blade 202 is used to initially cut the agricultural products entering the feeding bin 203 to reduce their size and facilitate subsequent filtration and crushing operations. In order to drive the cutting blade 202 to cut effectively, the filtration mechanism 2 also includes a motor 201. The motor 201 is fixedly connected to the outside of the feeding bin 203, and its output shaft is coaxially connected to the cutting blade 202 through a coupling or direct connection. When the motor 201 starts, the cutting blade 202 rotates at high speed to efficiently cut the agricultural products inside the feeding bin 203.

[0025] Below the feeding hopper 203, a filter screen 204 is installed. Cut agricultural products fall onto the filter screen 204 through holes at the bottom of the feeding hopper 203. The filter screen 204 is a key component for separating impurities; its mesh size is customized according to the characteristics of the agricultural product and the size of the impurities to ensure that the agricultural product can pass through while impurities such as stones are effectively intercepted. To improve filtration efficiency and prevent material accumulation on the filter screen 204, the filtration mechanism 2 also includes a vibration motor 206, which is fixedly connected to the bottom of the filter screen 204. When the vibration... When the motor 206 starts, the filter screen 204 generates high-frequency vibration. This vibration causes the material to bounce on the screen, prompting small particles of impurities to pass through the mesh and fall into the collection box 205. At the same time, it helps the agricultural products move forward on the filter screen 204, preventing blockage. In order to absorb the vibration generated by the motor 206 during operation and protect the fixed frame 1 and other components from excessive vibration, multiple sets of shock absorbers 207 are set between the filter screen 204 and the fixed frame 1 in the filtration mechanism 2. The shock absorbers 207 can effectively buffer and dissipate vibration energy to ensure the stable operation of the equipment.

[0026] Below the filter screen 204, a collection box 205 is also provided. The collection box 205 is used to collect impurities such as stones and mud that are screened out by the filter screen 204. The side wall of the collection box 205 extends upward along the two sides of the filter screen 204 to form a barrier structure. This barrier structure not only collects impurities, but more importantly, it acts as a barrier on both sides of the agricultural products on the filter screen 204, effectively preventing the agricultural products from falling off the sides of the filter screen 204 during vibration, and ensuring the flow and collection of materials. The agricultural products that have been effectively separated by the filter screen 204 are smoothly guided and slid into the feed inlet of the crusher 4 through the chute 5 at the discharge end of the filter screen 204. The inclination angle and internal smoothness of the chute 5 ensure the rapid and effective transportation of agricultural products and avoid midway stagnation.

[0027] The motor 201 used to drive the cutting blade 202 to rotate and the vibration motor 206 used to drive the filter screen 204 to vibrate can be implemented in a variety of conventional ways by those skilled in the art. Their specific internal structure and drive circuit are well known in the art and will not be described in detail here.

[0028] In a preferred embodiment, to ensure the initial processing effect of agricultural products when they enter the filtration mechanism 2, a cutting blade 202 is rotatably installed inside the feeding bin 203 above the filter screen 204 in the filtration mechanism 2. The cutting blade 202 is used to initially cut the agricultural products entering the feeding bin 203 to reduce their size. At the same time, the filtration mechanism 2 also includes a motor 201, which is fixedly connected to the outside of the feeding bin 203. Its output shaft is coaxially connected to the cutting blade 202 to drive the cutting blade 202 to rotate at high speed.

[0029] In a preferred embodiment, in order to improve the filtration efficiency of the filter screen 204 and solve the problem of material accumulation, the vibration motor 206 fixedly connected to the bottom of the filter screen 204 in the filter mechanism 2 uses continuous vibration to effectively separate agricultural products and impurities on the filter screen 204 and promote the material to move forward.

[0030] In a preferred embodiment, in order to absorb the vibration generated when the vibration motor 206 is working and to prevent the vibration from being transmitted to the entire fixed frame 1, a shock absorber 207 is provided in the filter mechanism 2 between the filter screen 204 and the fixed frame 1. The number and position of the shock absorbers 207 are optimized according to the actual vibration conditions and load-bearing requirements, effectively buffering and dissipating vibration energy to ensure the stable operation of the equipment.

[0031] In a preferred embodiment, in order to effectively collect the filtered impurities and prevent agricultural products from falling off the sides of the filter screen 204, the collection box 205 located below the filter screen 204 in the filter mechanism 2 has its sidewalls extending upward along the two sides of the filter screen 204 to form a U-shaped groove. This structure can accommodate the filtered impurities such as stones and also serve as a lateral barrier to the agricultural products on the filter screen 204.

[0032] In a preferred embodiment, in order to ensure that the filtered agricultural products can enter the crusher 4 smoothly and efficiently, the discharge end of the filter mechanism 2 and the feed end of the crusher 4 are connected by a chute 5. The inner surface of the chute 5 is smooth and has a suitable inclination angle to ensure that the agricultural products slide into the crusher 4 quickly under the action of gravity.

[0033] In a preferred embodiment, in order to provide a stable mounting base for the second motor 305, the lifting mechanism 3 also includes a placement plate 306, which is fixed to the fixing frame 1, and the second motor 305 is stably mounted on the placement plate 306.

[0034] As a preferred embodiment, in order to ensure that the power of the second motor 305 can be effectively and accurately transmitted to the gear 304, a turntable 303 is coaxially fixed to the output shaft of the second motor 305 in the lifting mechanism 3. The turntable 303 is fixedly connected to the gear 304 by a key connection or integral molding, so that when the second motor 305 rotates, the turntable 303 and the gear 304 can rotate synchronously, thereby accurately driving the rack 302 to perform lifting and lowering movements.

[0035] Working principle: When the equipment is running, the agricultural products are first fed into the feed hopper 203 through the feed port. Then, the motor 201 is started to drive the cutting blade 202 to cut the agricultural products inside the feed hopper 203. The products then fall onto the filter screen 204 through the lower hole. The vibration motor 206 is started to drive the filter screen 204 to vibrate and filter, filtering the stones in the agricultural products into the collection box 205. The collection boxes 205 on the left and right sides of the filter screen 204 prevent the agricultural products from falling. The shock absorber 207 at the bottom of the filter screen 204 provides shock absorption. The filtered agricultural products slide into the crusher 4 through the chute 5. Finally, the filter mechanism 2 is fixed on the fixed frame 1. The filter mechanism 2 avoids the blockage and damage to the machine caused by debris, improves the working efficiency of the crusher 4 and reduces maintenance costs. During operation, the second motor 305 is first placed on the placement plate 306, and the output of the second motor 305 is connected to the turntable 303. The turntable 303 and the gear 304 are fixedly connected together so that the gear 304 can rotate together when the turntable 303 rotates. The rack 302 meshes with the gear 304. The gear 304 and the rack 302 are placed together inside the support frame 301. After the filter screen 204 is running, the second motor 305 is started to drive the gear 304 to rotate, causing the rack 302 to move upward and lifting one side of the filter screen 204 upward. The second motor 305 is started to reverse so that the filter screen 204 falls downward. The lifting mechanism 3 avoids the situation of clogging caused by excessive accumulation of agricultural products on the top of the filter screen 204, thus improving the working efficiency of the filter screen 204.
