Abstract
Description
Technical Field
[0001] This utility model belongs to the field of agricultural product deep processing technology, specifically relating to a crushing and mixing equipment for agricultural product deep processing. Background Technology
[0002] Deep processing of agricultural products transforms primary agricultural products into high-value-added products, which not only increases the profit margin of the products, but also meets consumers' demand for diversified and high-quality food.
[0003] Currently, in the deep processing of agricultural products, raw materials are usually crushed by crushing equipment first, and then the crushed materials are transferred to mixing equipment for mixing. Because the crushing and mixing of agricultural products are carried out separately, the processing efficiency of agricultural products is low.
[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content
[0005] The purpose of this utility model is to provide a crushing and mixing equipment for deep processing of agricultural products, which can solve the problem of low processing efficiency caused by crushing and mixing agricultural products in different devices.
[0006] To achieve the above objectives, the technical solution provided by a specific embodiment of this utility model is as follows:
[0007] A crushing and mixing device for deep processing of agricultural products includes:
[0008] The equipment body includes a housing, on which a cover plate is installed. The cover plate is installed on the housing in a detachable manner, which facilitates the maintenance of the internal components of the housing.
[0009] The crushing and grinding mechanism includes a rotating shaft rotatably connected to a cover plate. Multiple sets of spiral blades are mounted on the side wall of the housing from top to bottom. Rotation of the shaft drives the spiral blades to rotate, crushing the agricultural products within the housing. The serrated edges of the spiral blades further enhance the crushing effect. A grinding layer is provided on the inner side wall of the housing. Multiple grinding protrusions are integrally formed at equal intervals on the spiral blade-facing side of the grinding layer. When the spiral blades rotate at high speed, the material is pushed and thrown towards the grinding layer and grinding protrusions. Within the gap between the spiral blades and the grinding protrusions, the material is subjected to compression and shearing forces. This results in the agricultural products being crushed by the shearing action of the spiral blades and the grinding action of the grinding layer and grinding protrusions within the housing, effectively improving the crushing effect and thus increasing the processing efficiency of the agricultural products.
[0010] The screening mechanism includes multiple first screens and second screens. The first screens are installed on a cover plate and are used to screen agricultural products entering the shell. The second screens are installed on the bottom wall plate of the shell and are used by crushing blades to screen the crushed agricultural products, so as to separate agricultural products with qualified particle size after crushing, and to allow larger particles of agricultural products to be intercepted by the crushing blades and then repeatedly ground and crushed inside the shell.
[0011] In one or more embodiments of this utility model, the top of the housing is integrally formed with a mounting ring, the cover plate is mounted on the mounting ring, and a plurality of fixing bolts are installed at equal intervals between the cover plate and the mounting ring. The fixing bolts fix the cover plate while making the cover plate easy to install and remove.
[0012] In one or more embodiments of this utility model, the spacing between the multiple sets of spiral blades is set in a manner that gradually decreases from top to bottom, thereby making the spiral blades at the bottom densely arranged to improve the crushing efficiency of agricultural products.
[0013] In one or more embodiments of this utility model, a plurality of grinding bosses are arranged in a direction along the axial direction of the housing, and all of the plurality of grinding bosses are configured as wavy, thereby increasing the contact area between the material and the grinding bosses and improving the grinding and crushing efficiency.
[0014] In one or more embodiments of this utility model, the cover plate is provided with multiple feed inlets at equal intervals, and multiple first screens are respectively installed in the multiple feed inlets, so that the first screens screen the agricultural products and then enter the shell through the feed inlets.
[0015] In one or more embodiments of this utility model, a barrier is fixedly connected to the cover plate. The barrier is arranged around the periphery of the plurality of feed inlets to shield the agricultural products on the cover plate and ensure that the agricultural products enter the housing after being screened by the first screen.
[0016] In one or more embodiments of this utility model, a pair of first stirring impellers are fixedly connected to the side wall of the rotating shaft. Multiple crushing blades are fixedly connected to the front and rear side walls of the pair of first stirring impellers. The pair of first stirring impellers are arranged above the first screen. When the rotation of the rotating shaft drives the pair of first stirring impellers to rotate, the first stirring impellers will drive the multiple crushing blades to rotate. Thus, the agricultural products on the first screen can be rotated by the first stirring impellers and the crushing blades, thereby breaking up the agglomerated agricultural products and improving the screening efficiency of the first screen for agricultural products.
[0017] In one or more embodiments of this utility model, a discharge port is provided on the bottom wall panel of the shell, and the second screen is installed inside the discharge port, so that the agricultural products that have been crushed inside the shell are discharged through the discharge port after being screened by the second screen.
[0018] In one or more embodiments of this utility model, a conveying pipe is fixedly connected to the lower end of the bottom wall panel of the housing. The conveying pipe is located at the bottom of the outlet, so that the agricultural products discharged from the outlet are guided through the conveying pipe and discharged.
[0019] In one or more embodiments of this utility model, a pair of second stirring impellers are fixedly connected to the bottom side wall of the rotating shaft. The pair of second stirring impellers are arranged above the second screen. When the rotating shaft drives the pair of second stirring impellers to rotate, the pair of second stirring impellers can stir and mix the agricultural products at the bottom of the shell, so that the crushed agricultural products are mixed evenly and the screening efficiency of the second screen for agricultural products is improved.
[0020] Compared with existing technologies, this invention uses high-speed rotating spiral blades to crush agricultural products. Under the action of centrifugal force, the agricultural products are thrown towards the grinding parts, so that the agricultural products are subjected to compression and shearing forces in the gap, which improves the crushing effect. At the same time, the agricultural products are screened simultaneously during crushing, so that the agricultural products are evenly mixed and discharged through the screen, which improves the processing efficiency of agricultural products.

Detailed Implementation
[0030] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of 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 some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
[0031] like Figures 1-3 As shown in the figure, a crushing and mixing device for deep processing of agricultural products in one embodiment of the present invention includes a device body 1, a crushing and grinding mechanism 2 and a screening mechanism 3.
[0032] like Figures 1-3As shown, the device body 1 includes a housing 11, and a cover plate 12 is installed on the housing 11. The cover plate 12 is installed on the housing 11 in a detachable manner, which makes it convenient to maintain the internal components of the housing 11.
[0033] like Figures 1-3 As shown, the top of the housing 11 is integrally formed with a mounting ring 13, and the cover plate 12 is mounted on the mounting ring 13. Multiple fixing bolts 14 are installed at equal intervals between the cover plate 12 and the mounting ring 13. The fixing bolts 14 fix the cover plate 12 and make it easy to disassemble and assemble the cover plate 12.
[0034] like Figure 2 and Figure 3 As shown, the crushing and grinding mechanism 2 includes a rotating shaft 21, which is rotatably connected to the cover plate 12 through a through-hole. Multiple sets of spiral blades 22 are mounted on the side wall inside the housing 11 from top to bottom on the rotating shaft 21. The rotation of the rotating shaft 21 drives the spiral blades 22 to rotate, thus crushing the agricultural products inside the housing 11. The spiral blades 22 have serrated edges, enabling them to crush the agricultural products. A grinding layer 23 is provided on the inner side wall of the housing 11. Multiple grinding protrusions 24 are integrally formed at equal intervals on the side of the grinding layer 23 facing the spiral blades 22. When the spiral blades 22 rotate at high speed, the material is pushed and thrown towards the grinding layer 23 and the grinding protrusions 24. The material is subjected to compression and shearing forces in the gap between the spiral blades 22 and the grinding protrusions 24, thereby effectively improving the crushing effect of the agricultural products and increasing the processing efficiency. At the same time, when the agricultural products are crushed by the high rotation of the spiral blade 22, the agricultural products are rotated inside the shell 11, which causes the crushed agricultural products to be separated under the action of centrifugal force. This allows for repeated crushing and grinding of agricultural products with larger particle sizes, making the crushed agricultural products have uniform particle size. This ensures that the agricultural products are evenly mixed through crushing, thereby achieving efficient crushing and mixing of agricultural products inside the shell 11.
[0035] like Figures 2-6 As shown, the screening mechanism 3 includes multiple first screens 31 and second screens 34. The multiple first screens 31 are installed on the cover plate 12 and are used to screen agricultural products entering the shell 11. The second screens 34 are installed on the bottom wall plate of the shell 11 and are used by the crushing blades 33 to screen the crushed agricultural products so as to screen out agricultural products with qualified particle size after crushing, so that the larger particle size agricultural products are intercepted by the crushing blades 33 and then repeatedly ground and crushed in the shell 11.
[0036] Preferably, the spacing between the multiple sets of spiral blades 22 is set in a manner that gradually decreases from top to bottom, so that the spiral blades 22 at the bottom are densely arranged, thereby improving the crushing efficiency of agricultural products.
[0037] like Figure 3 As shown, multiple grinding protrusions 24 are arranged along the axial direction of the housing 11, and all of the grinding protrusions 24 are configured in a wave shape. By increasing the contact area between the material and the grinding protrusions 24, the grinding and crushing efficiency is improved.
[0038] like Figure 2 As shown, a motor 25 is installed on the top of the rotating shaft 21. The motor 25 is a high-speed motor so that the rotating shaft 21 can be driven to rotate quickly, so that the spiral blades 22 can crush agricultural products by rotating at high speed.
[0039] like Figure 4 and Figure 6 As shown, the cover plate 12 has multiple feed inlets 15 at equal intervals, and multiple first screens 31 are respectively installed in the multiple feed inlets 15, so that the first screens 31 screen the agricultural products and then enter the shell 11 through the feed inlets 15.
[0040] like Figure 1 and Figure 2 As shown, a barrier 36 is fixedly connected to the cover plate 12. The barrier 36 is set around the periphery of multiple feed inlets 15 to cover the agricultural products on the cover plate 12 and ensure that the agricultural products enter the shell 11 after being screened by the first screen 31.
[0041] like Figure 4 and Figure 6 As shown, a pair of first stirring impellers 32 are fixedly connected to the side wall of the rotating shaft 21. Multiple crushing blades 33 are fixedly connected to the front and rear side walls of the pair of first stirring impellers 32. The pair of first stirring impellers 32 are positioned above the first screen 31. When the rotation of the rotating shaft 21 drives the pair of first stirring impellers 32 to rotate, the first stirring impellers 32 will drive the multiple crushing blades 33 to rotate. Thus, the agricultural products on the first screen 31 can be rotated through the first stirring impellers 32 and the crushing blades 33, thereby breaking up the agglomerated agricultural products and improving the screening efficiency of the first screen 31 for agricultural products.
[0042] like Figure 3 Combination Figure 5 As shown, a discharge port 16 is provided on the bottom wall panel of the shell 11, and a second screen 34 is installed inside the discharge port 16, so that the agricultural products that have been crushed inside the shell 11 are screened by the second screen 34 and discharged through the discharge port 16.
[0043] Optionally, the second screen 34 can be equipped with an adjustable aperture screen or be installed in a way that facilitates disassembly and assembly, so that the screen with the appropriate aperture can be replaced according to the particle size requirements of agricultural product processing, thereby improving the practicality of the device.
[0044] like Figure 1 and Figure 5 As shown, a conveying pipe 37 is fixedly connected to the lower end of the bottom wall panel of the housing 11. The conveying pipe 37 is located at the bottom of the outlet 16, so that the agricultural products discharged from the outlet 16 are discharged after being guided by the conveying pipe 37.
[0045] like Figure 3 Combination Figure 5 As shown, a pair of second stirring impellers 35 are fixedly connected to the bottom side wall of the rotating shaft 21. The pair of second stirring impellers 35 are arranged above the second screen 34. When the rotating shaft 21 drives the pair of second stirring impellers 35 to rotate, the pair of second stirring impellers 35 can stir and mix the agricultural products at the bottom of the shell 11, so that the crushed agricultural products are mixed evenly and the screening efficiency of the second screen 34 on the agricultural products is improved.
[0046] In use, the agricultural products to be crushed are added into the enclosure 36. When the rotating shaft 21 drives the first stirring impeller 32 to rotate, the first stirring impeller 32 and the crushing blade 33 will stir and disperse the agricultural products, so that the agricultural products are screened through the first screen 31 and enter the shell 11. When the agricultural products enter the shell 11, they are crushed under the high-speed rotation of multiple sets of first stirring impellers 32. The high-speed rotation of the first stirring impeller 32 causes the agricultural products to be crushed and thrown onto the crushing blade 33 and the second screen 34 by centrifugal force. They are squeezed and sheared in the gap between the spiral blade 22 and the grinding boss 24, so that the agricultural products are crushed by the shearing of the spiral blade 22 and the grinding of the grinding layer 23 and the grinding boss 24 in the shell 11. After crushing, the agricultural products with small particle size are stirred and mixed by the second stirring impeller 35 and then screened through the second screen 34 and discharged from the shell 11. At the same time, the agricultural products with larger particle size are carried away by centrifugal force for repeated crushing and grinding, thereby improving the processing efficiency of agricultural products.
[0047] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
