Abstract
Description
Technical Field
[0001] This utility model relates to the field of solid food testing technology, specifically a crushing device for solid food testing. Background Technology
[0002] Food testing is a discipline that studies and evaluates the quality and changes of food. Based on fundamental theories of physics, chemistry, and biochemistry, and various techniques, it inspects the quality of food raw materials, auxiliary materials, semi-finished products, finished products, and by-products according to established technical standards, such as international and national food hygiene standards, to ensure product quality compliance. In the practice of food testing, the grinding device used for solid food testing plays a crucial role. This specialized device, through its efficient working mechanism, can finely grind or homogenize solid food samples, providing a uniform sample for subsequent physical, chemical, and biochemical analyses, greatly improving the accuracy and efficiency of testing.
[0003] According to the published patent CN219631459U, a crushing device for testing solid food includes a housing, a crushing mechanism provided on the inner wall of the housing, a vibration mechanism provided on the top of the housing, a crushing chamber slidably connected to the inner wall of the housing, a bearing fixedly connected to the inner wall of the crushing chamber, a smooth rod fixedly connected to the inner ring of the bearing, and a vibration block slidably connected to the inner wall of the housing. The top of the housing has a vibration groove for cooperating with the vibration block. This solid food testing and pulverizing device incorporates a vibration mechanism. The vibrating block drives the pulverizing chamber to vibrate, thereby enabling the sieve to quickly sift out the desired sample. This prevents large pieces of solid food from clogging the sieve and hindering its sieving efficiency. In developing this invention, the inventors discovered at least the following unresolved problems in existing technologies: While the vibrating sieve solves the problem of solid food accumulating and clogging the sieve surface, in actual use, when large solid food samples are poured into the housing and brought into contact with the pulverizing mechanism, the large food samples, especially those with a smooth surface due to water droplets, experience insufficient friction during contact pulverization. This leads to the food sample easily shaking inside the housing, affecting the pulverizing efficiency of the mechanism. Therefore, a new technical solution is needed to address these issues. Utility Model Content
[0004] The purpose of this invention is to overcome the shortcomings of the existing technology, adapt to practical needs, and provide a crushing device for solid food testing. This device solves the technical problem that when a large number of water droplets adhere to the surface of a large solid food sample, the surface of the food sample is relatively smooth. As a result, when the food sample is crushed by the crushing mechanism, the contact friction between the food sample and the crushing mechanism is insufficient, which easily causes the food sample to shake inside the shell and affects the crushing efficiency of the crushing mechanism.
[0005] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: a crushing device for solid food testing is designed, including a box body, a rotating cover is hinged to the top side of the box body through a rotating shaft, a screening screen plate is slidably installed inside the box body, and a guide plate is fixedly installed at the bottom inside the box body.
[0006] A hollow frame is fixedly installed on the top center surface of the rotating cover. A pushing mechanism is provided inside the hollow frame. Push plates are provided on both sides of the bottom of the rotating cover, and the pushing mechanism and the push plates are connected in a transmission manner.
[0007] The screen plate is detachably equipped with a crushing mechanism on both sides of the top. The bottom of the inner side of the box is fixedly equipped with a rotating motor. The top of the rotating motor drive shaft is fixedly equipped with a transmission rod through a coupling, and the top of the transmission rod is connected to the crushing mechanism.
[0008] Preferably, the pushing mechanism includes a pushing spring and a pushing rod. An installation rod is horizontally fixedly installed at the middle of the inner side of the hollow frame. Extrusion sleeves are slidably sleeved on both outer sides of the installation rod. A fixing rod is fixedly installed on the bottom outer side of each extrusion sleeve. Sliding grooves are opened on both sides of the bottom of the hollow frame, and the fixing rod is slidably inserted into the sliding groove. A pushing spring is movably sleeved on the middle outer side of the installation rod, and the two ends of the pushing spring are movably attached to the outside of the extrusion sleeve.
[0009] Preferably, a connecting plate is fixedly installed between the two ends of the sides of the two sets of push plates, and a connecting frame is fixedly installed on the top of each fixed rod and the side of the connecting plate. A push rod is hinged between the sides of each pair of connecting frames via a pivot.
[0010] Preferably, guide rods are vertically fixedly installed on both sides of the top center of the push plate, and limit grooves are opened inside both ends of the side of the hollow frame, with the guide rods slidingly inserted into the limit grooves.
[0011] Preferably, the crushing mechanism includes a rotating disk and a fixed disk. The top of the transmission rod and the bottom surface of the rotating disk are fixedly connected, and the rotating disk rotates and fits against the top surface of the screening screen plate. A connecting bolt is vertically fixedly installed at the top middle of the rotating disk. The fixed disk is slidably sleeved on the outside of the connecting bolt. A crushing blade is fixedly installed on the outer surface of the fixed disk, and the number of crushing blades is several sets. A connecting screw is threaded to the top of the connecting bolt, and the connecting screw is located on the top of the outer side of the fixed plate.
[0012] Preferably, a discharge trough is provided on the bottom side of the box body, and a sealing cover plate is detachably installed on the side of the box body by bolts, and the sealing cover plate is located outside the discharge trough. Movable grooves are provided inside both sides of the screening screen plate. The diameter of the rotating disk is the same as the diameter of the movable groove, and the rotating disk is located above the outside of the movable groove.
[0013] Preferably, guide grooves are provided inside both ends of the side of the box, and guide blocks are fixedly installed on both ends of the outer side of the screening screen plate, and the guide blocks are slidably inserted into the guide grooves.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0015] 1. This utility model features an installation rod inside the hollow frame on the outer side of the rotating cover, and movable extrusion sleeves fitted on both sides of the installation rod surface. A rotating shaft hinges the two sides of the push rod to the extrusion sleeves and the outer side of the push plate, respectively. When the rotating cover is rotated, causing the push plate to flip inside the housing, the push plate can press against the top surface of a large sample to be crushed. Under the pressure of the large sample, the push plate is vertically lifted outwards from the hollow frame, while the push rod is simultaneously raised. The extrusion sleeve is supplied with a corresponding pushing force, causing it to move synchronously towards each other on the surface of the mounting rod. This compresses the push spring, causing it to deform, while the push spring pushes the extrusion sleeve in the opposite direction. As the sample to be crushed is reduced in size, the push plate remains in constant contact with the top surface of the sample, providing a corresponding vertical pushing force to the top of the sample. This ensures that the sample can fully contact the crushing blades, thus preventing the sample surface from becoming too slippery and affecting the crushing efficiency.
[0016] 2. This utility model, by installing a fixed plate on the top of the transmission rod and setting connecting bolts on the surface of the fixed plate, combined with the twisting and connecting action of the connecting screw, allows the rotating disk and the crushing blade to be detachably installed on the surface of the fixed plate. After crushing and screening large pieces of sample to be crushed using the sieve plate and the crushing blade, the crushing blade can be quickly removed from the surface of the sieve plate, and the sieve plate can be lifted and removed from the inside of the box for quick and convenient cleaning of the sample residue accumulated on its surface. This reduces the labor required for cleaning the surface of the sieve plate while ensuring the sorting quality of the crushed and screened food samples by the sieve plate. Attached Figure Description

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments:
[0027] Example 1: A crushing device for testing solid food, see [link to example]. Figures 1 to 4A rotating cover 11 is hinged to the top side of the box 1 via a pivot. A screening screen 12 is slidably installed inside the box 1. A guide plate 13 is fixedly installed at the bottom inside the box 1. A hollow frame 2 is fixedly installed on the top middle surface of the rotating cover 11. A pushing mechanism is installed inside the hollow frame 2. Push plates 27 are installed on both sides of the bottom of the rotating cover 11, and the pushing mechanism and the push plates 27 are connected in a transmission. A crushing mechanism is detachably installed on both sides of the top of the screening screen 12. A rotating motor 3 is fixedly installed at both ends of the bottom inside the box 1. A transmission rod 31 is fixedly installed on the top of the transmission shaft via a coupling, and the top of the transmission rod 31 is connected to the crushing mechanism. Under the structural action of the pushing mechanism and the crushing mechanism, the pushing plate 27 can always abut against the top surface of the large sample to be crushed during the crushing process, providing the top of the large sample to be crushed with a corresponding vertical pushing force, so that the sample can fully contact the crushing blade 35, thereby avoiding the sample surface being too slippery and affecting the crushing efficiency of the sample.
[0028] For details, see Figures 1 to 4 The pushing mechanism includes a pushing spring 23 and a pushing rod 28. An installation rod 21 is horizontally fixedly installed at the middle of the inner side of the hollow frame 2. Extrusion sleeves 22 are slidably sleeved on both outer surfaces of the installation rod 21. A fixing rod 24 is fixedly installed on the bottom outer surface of each extrusion sleeve 22. Sliding grooves 29 are opened on both sides of the bottom of the hollow frame 2, and the fixing rod 24 is slidably inserted into the sliding groove 29. The pushing spring 23 is movably sleeved on the middle outer surface of the installation rod 21, and the two sides of the pushing spring 23 are movably attached to the outside of the extrusion sleeve 22. Under the pushing action of the pushing spring 23 on the extrusion sleeve 22, the pushing plate 27 can always abut against the top surface of the large sample to be crushed during the crushing and volume reduction process.
[0029] Further, see Figures 1 to 4 A connecting plate 25 is fixedly installed between the two ends of the two sets of push plates 27. A connecting frame 26 is fixedly installed on the top of each fixed rod 24 and the side of the connecting plate 25. A push rod 28 is hinged between the sides of each pair of connecting frames 26 via a rotating shaft. Under the transmission conversion action of the push rod 28, the vertical moving force of the push plate 27 and the horizontal moving force of the extrusion sleeve 22 can be converted into each other, thereby ensuring that the push plate 27 can always be in contact with the sample surface for pushing treatment.
[0030] It is worth noting that, see Figures 1 to 4Guide rods 4 are vertically fixed on both sides of the top middle of the push plate 27. Limiting grooves 41 are opened inside both ends of the side of the hollow frame 2. The guide rods 4 are slidably inserted into the limiting grooves 41. Under the guiding sliding action of the limiting grooves 41 on the guide rods 4, the push plate 27 can only move vertically when it is resisted by a large food sample, so as to provide the corresponding horizontal pushing force to the extrusion sleeve 22, thereby ensuring the rationality of the transmission of the overall mechanism.
[0031] It is worth noting that, see Figures 1 to 4 The crushing mechanism includes a rotating disk 36 and a fixed disk 34. The top of the transmission rod 31 is fixedly connected to the bottom surface of the rotating disk 36, and the rotating disk 36 rotates and fits against the top surface of the screening screen plate 12. A connecting bolt 32 is vertically fixedly installed at the middle of the top of the rotating disk 36. The fixed disk 34 is slidably sleeved on the outside of the connecting bolt 32. Crushing blades 35 are fixedly installed on the outer surface of the fixed disk 34, and there are several sets of crushing blades 35. A connecting screw 33 is screwed to the top of the connecting bolt 32 through threads, and the connecting screw 33 is located on the top of the outer side of the fixed plate. The rotating disk 36 and the fixed disk 34 can be detached and separated by the connecting bolt 32 and the connecting screw 33, which facilitates the removal of the screening screen plate 12 and the subsequent cleaning of the surface of the screening screen plate 12.
[0032] It is worth mentioning that, see Figures 1 to 4 The bottom side of the box 1 has a discharge trough 14. A sealing cover 15 is detachably installed on the side of the box 1 by bolts, and the sealing cover 15 is located outside the discharge trough 14. Movable grooves 37 are opened inside both sides of the screening screen plate 12. The diameter of the rotating disk 36 is the same as the diameter of the movable groove 37, and the rotating disk 36 is located above the outside of the movable groove 37. Under the structural action of the discharge trough 14, the crushed material can be discharged and removed.
[0033] It is worth mentioning that, see Figures 1 to 4 The box body 1 has guide grooves 5 inside both sides. The outer two ends of the screening screen plate 12 are fixedly installed with guide blocks 51, and the guide blocks 51 are slidably inserted into the guide grooves 5. Under the guiding sliding action of the guide grooves 5 on the guide blocks 51, the screening screen plate 12 can only be lifted vertically inside the box body 1 after being lifted, and will not tilt, thereby ensuring the carrying capacity of the screening screen plate 12 for the sample material and the screening stability.
[0034] During operation, a large food sample to be crushed is placed on the surface of the screening screen plate 12 inside the housing 1. The rotating cover 11 is then rotated and flipped to fit against the top of the housing 1, allowing the bottom of the push plate 27 to fit against the top surface of the large food sample. When the push plate 27 is pushed against by the top of the food sample, under the vertical guiding sliding action of the guide rod 41 by the limiting slide groove 41, the push plate 27 moves towards the outer bottom of the hollow frame 2. Subsequently, under the transmission conversion action of the push rod 28, the vertical moving force of the push plate 27 can be converted into a horizontal pushing force on the extrusion sleeve 22. This allows the two sets of extrusion sleeves 22 to move horizontally towards each other on the surface of the mounting rod 21. Simultaneously, the push spring 23, fitted onto the surface of the mounting rod 21, causes it to deform under pressure. Bolts are then used to fix the rotating cover 11 to the top surface of the housing 1. Subsequently, the two sets of rotating motors 3 are started, causing them to rotate and drive the transmission rod 31 and the fixed disk 34 to rotate synchronously. This, in turn, drives the rotating disk 36, which is fitted onto the surface of the fixed disk 34, and the pulverizing blades 35 on its outer side to rotate synchronously, thus pulverizing the food sample. As the volume of the food sample decreases, it provides material to the push plate. After the force of the push spring 23 changes, the two sets of push sleeves 22 can move horizontally on the surface of the mounting rod 21 synchronously under the reverse pushing action of the push spring 23 on the extrusion sleeve 22. Then, under the transmission conversion action of the push rod 28, a corresponding pushing force is provided to the push plate 27, so that the push plate 27 can always push against the top of the food sample, thereby ensuring full contact between the food sample and the crushing blade 35 for rapid crushing. After the food sample is screened by the screening screen plate 12, the food sample with qualified diameter can fall onto the guide plate 1. 3. After opening the sealing cover 15 to remove the food sample accumulated on the surface of the guide plate 13, when it is necessary to clean the surface of the sieve plate 12, the connecting screw 33 is turned to remove it from the top of the connecting bolt 32, and then the rotating disk 36 is lifted to move the crushing blade 35 away from the surface of the rotating disk 36. Then the sieve plate 12 is lifted and pulled. Under the guiding sliding action of the guide groove 5 on the guide block 51, the fixed plate can pass through the sliding groove 29, and the sieve plate 12 is removed from the inside of the box 1 to clean the surface of the sieve plate 12.
