Description

Technical Field

[0001] This utility model relates to the field of microbial fertilizer technology, specifically a microbial fertilizer granule grading and screening machine. Background Technology

[0002] Microbial fertilizers are products that produce specific fertilizer effects on crops through the life activities of microorganisms. They are a type of fertilizer used in agricultural production and contain preparations of specific active microorganisms. Through the life activities of microorganisms, they improve plant nutrition or promote growth. They are environmentally friendly agricultural inputs. The screening of microbial fertilizer particles is a key step in the production process, which directly affects the uniformity of product particle size, application effect and mechanical adaptability. Traditional microbial fertilizer granule grading and screening machines cannot effectively control the temperature during screening. Since the equipment inevitably generates heat during operation, the temperature during filtration increases over time. This can cause beneficial microorganisms inside the fertilizer to die under high temperatures. Even if they survive, the high temperature can cause the microorganisms to enter a state of "heat shock," which will affect the subsequent quality of the fertilizer and cause inconvenience to operators. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a microbial fertilizer granule grading and screening machine. This solves the problem that traditional microbial fertilizer granule grading and screening machines cannot effectively control the temperature during screening.

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0013] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0014] Traditional microbial fertilizer granule grading and screening machines cannot effectively control the temperature during screening. Since the equipment inevitably generates heat during operation, the temperature during filtration increases over a long period of time. This can cause beneficial microorganisms inside the fertilizer to die under high temperatures. Even if they do not die, the high temperature can cause the microorganisms to be in a state of "heat shock," which will affect the quality of the fertilizer in subsequent use and cause inconvenience to the operators. In view of this, the present invention provides a microbial fertilizer granule grading and screening machine. Through the cooperation of the base plate, box body, water tank, pump body, connecting pipe, drain pipe, temperature sensor, compressor and heat conduction plate, the internal temperature environment of the equipment can be guaranteed during screening, thereby avoiding excessive internal temperature due to prolonged operation. This ensures the activity of beneficial microorganisms during screening, guarantees the quality of subsequent fertilizer use, and facilitates the use by operators.

[0015] Example 1: By Figure 1 , 2As can be seen from points 3 and 4, a microbial fertilizer granule grading and screening machine includes a base plate 1, a box body 2 fixedly connected to the top of the base plate 1, a water tank 3 fixedly connected to the outer wall of the box body 2, and the bottom of the water tank 3 fixedly connected to the top of the base plate 1. A pump body 4 is fixedly connected to one side of the top of the base plate 1. A connecting pipe 5 is connected to the output end of the pump body 4, and the connecting pipe 5 is connected to the inner wall of the box body 2. A drain pipe 6 is connected to the upper side of one side of the box body 2. A heat-conducting plate 7 is fixedly connected to the inner wall of the box body 2. A compressor 8 is fixedly connected to one side of the inner wall of the water tank 3. In the specific implementation process, it is worth noting that there are no restrictions on the models of pump body 4 and compressor 8, as long as they meet the usage requirements. The process of compressor 8 cooling water is achieved through a refrigeration cycle, which includes four stages: compression, condensation, expansion, and evaporation. The refrigerant (such as R134a, R410A, etc.) circulates in a closed system and absorbs heat from the water through indirect heat exchange, thereby reducing the water temperature. Therefore, this case will not elaborate on this. Pump body 4 can draw cooling water into the interior of box 2, and then exchange heat with the air inside box 2 through heat conduction plate 7. Furthermore, a temperature sensor 9 is fixedly connected to the top side of the housing 2; In the specific implementation process, it is worth noting that the model of temperature sensor 9 is not limited, as long as it meets the usage requirements. Temperature sensor 9 can monitor the temperature inside the box 2 in real time, and this case should be equipped with an external control terminal that works with temperature sensor 9. Temperature sensor 9 can transmit signals to the external control terminal, and then the signals transmitted by temperature sensor 9 can be analyzed and processed so that the staff can know the temperature inside the box 2 in a timely and accurate manner. Furthermore, a feed hopper 10 is fixedly connected to the top of the box 2, a cover 11 is sleeved on the top of the feed hopper 10, and a baffle plate 12 is inserted into the inner wall of the feed hopper 10. In the specific implementation process, it is worth noting that the cover 11 can close and seal the feed hopper 10, and the baffle plate 12 can block the material inside the feed hopper 10. At the same time, the feed hopper 10 can be closed during screening to avoid a large amount of interaction between the outside air and the low temperature air inside the box 2 when replenishing material. Specifically, when using this microbial fertilizer granule grading and screening machine, the operator opens the cover 11, pours the material into the feed hopper 10, closes the cover 11, and pulls the baffle 12. The material then enters the chamber 2 through the feed hopper 10 for screening. At the same time, the temperature sensor 9 monitors the temperature inside the chamber 2 in real time. When the temperature is too high, the pump 4 is turned on, and the pump 4 draws cooling water into the chamber 2. Heat exchange occurs through the heat conduction plate 7, and the cooling water flows back to the water tank 3 through the drain pipe 6. Then, the compressor 8 is turned on to cool the water, thus ensuring the cooling quality of the water.

[0016] Example 2: From Figure 1 , 2 As shown in section 3, multiple vertical rods 22 are fixedly connected to the top of the base plate 1. The outer walls of the multiple vertical rods 22 are all fitted with first sleeves 19. The upper part of the outer walls of the multiple vertical rods 22 is fitted with second sleeves 20. The outer walls of the multiple first sleeves 19 are fixedly connected with first sieve boxes 17. The outer walls of the multiple second sleeves 20 are fixedly connected with second sieve boxes 14. The bottom of the second sieve box 14 is fixedly connected with a connecting plate 15 that is fixedly connected to the top of the first sieve box 17. The bottom of the second sieve box 14 is fixedly connected with a vibration motor 16. The tops of the multiple vertical rods 22 are all fixedly connected with springs 21. The tops of the multiple springs 21 are respectively fixedly connected to the top of the inner walls of the multiple second sleeves 20. The top of the base plate 1 is attached to a collection box 18. In the specific implementation process, it is worth noting that the model of the vibrating motor 16 is not limited, as long as it meets the usage requirements. The vibrating motor 16 can drive the first screen box 17 and the second screen box 14 to vibrate. At this time, the first screen box 17 and the second screen box 14 can be used to classify and screen materials. The bottom of the first screen box 17 and the second screen box 14 are equipped with screen plates. The specific mesh size of the screen plates is not limited, as long as it meets the usage requirements. Moreover, the staff should regularly disassemble and clean the screen plates at the bottom of the first screen box 17 and the second screen box 14 to avoid screen plate blockage, which would lead to a decrease in screening quality. 4. Both water tank 3 and tank body 2 are equipped with door panels, which allows workers to more conveniently remove materials from the first screen box 17, the second screen box 14 and the collection box 18, and also facilitates the inspection and maintenance of pump body 4. It should be noted that locks should be installed between the multiple door panels and the first screen box 17, the second screen box 14, water tank 3 and tank body 2, so that the door panels can be fixed to the first screen box 17, the second screen box 14, water tank 3 and tank body 2. The specific structure, operation steps and usage of the locks are not limited, and these are all existing technologies known to those skilled in the art. Therefore, this case will not elaborate on this point. Furthermore, the outer side of the vibrating motor 16 is fitted with a protective plate that is fixedly connected to the bottom of the second screen box 14, the inner wall of the collection box 18 is slidably snapped with a limiting strip that is fixedly connected to the top of the bottom plate 1, and the top of the inner wall of the box body 2 is fixedly connected with a limiting plate 13 that is attached to the upper part of the outer wall of the second screen box 14. In the specific implementation process, it is worth noting that the protective plate can isolate and protect the vibratory motor 16. Its material should be a high heat dissipation material so that the heat of the vibratory motor 16 can be dissipated quickly during operation. The specific material is not limited, as long as it meets the usage requirements. The material limiting plate 13 can limit the material falling from the feed hopper 10 to prevent the phenomenon of material splashing. Specifically, based on the above embodiment one, when screening is performed, the vibration motor 16 is turned on, which drives the second screen box 14 to move. At the same time, the first screen box 17 is driven to move through the connecting plate 15. Meanwhile, the first sleeve 19 and the second sleeve 20 move along the outer wall of the vertical rod 22 and change the shape of the spring 21. At this time, the elastic potential energy of the spring 21 can cause the first screen box 17 and the second screen box 14 to vibrate repeatedly, thereby realizing the grading and screening of materials.

[0017] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
