Description

Technical Field

[0001] This utility model relates to the field of fertilizer testing technology, specifically a processing device for fertilizer testing. Background Technology

[0002] In fertilizer testing, sample preparation is a core step to ensure accurate and reliable test results. This process involves multiple steps, including crushing, sieving, dissolving, extraction, heating, and vibration, requiring a series of specialized devices and supporting equipment. This application primarily focuses on improving the crushing device. By crushing solid fertilizers (such as granular fertilizers and organic fertilizers) to a uniform particle size, the crushing device effectively breaks down the fertilizer particle structure, fully exposing the internal nutrients and ensuring efficient nutrient release and accurate measurement in subsequent dissolving and extraction steps.

[0003] However, in existing technologies, grinding equipment is generally used to grind fertilizers into a relatively fine state to facilitate subsequent testing. Traditional equipment often employs a fixed structural design. While it can process fertilizers to a fine state using grinding discs or ball mills, its large size and non-foldable components make it difficult to adapt to the rapid switching requirements between laboratory and field settings. Especially in field sampling or mobile testing scenarios, carrying the equipment requires a significant amount of space.

[0004] Therefore, the aforementioned technical pain points require a fertilizer testing processing device to solve them. Utility Model Content

[0005] The purpose of this invention is to provide a fertilizer testing device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fertilizer testing processing device, comprising a grinding chamber, wherein a grinding mechanism is provided inside the grinding chamber, the grinding mechanism comprising a movable frame, a motor, a transmission rod, a grinding head, and grinding teeth. A movable frame is movably inserted into the upper part of the grinding chamber, allowing the movable frame to move up and down at the upper end of the grinding chamber. A motor is fixedly installed inside the movable frame, and a transmission rod is fixedly installed at the power output shaft end of the motor. A grinding head is fixedly installed at the lower end of the transmission rod. A plurality of grinding teeth are uniformly fixedly installed at the lower end of the grinding chamber. A collection mechanism for the crushed fertilizer is provided at the lower end of the grinding chamber, the collection mechanism comprising a base plate, a connecting rod, a threaded ring, a first thread, and a second thread. A base plate is provided at the lower end of the grinding chamber, and a plurality of connecting rods are uniformly fixedly installed around the outer surface of the base plate. A threaded ring is fixedly installed at the upper end of the connecting rod. A first thread is provided at the lower end of the outer surface of the grinding chamber, and a second thread is provided at the upper end of the first thread on the outer surface of the grinding chamber. The threaded ring can be connected to the first thread or the second thread by rotation.

[0007] Preferably, the outer surface of the rotating sleeve is provided with an anti-slip groove, which allows the rotating sleeve to be rotated easily.

[0008] Preferably, the outer surface of the rotating sleeve is provided with an anti-slip groove, which allows the rotating sleeve to be rotated easily.

[0009] Preferably, a groove is provided in the middle of the upper end of the base plate, and a storage cup is movably engaged inside the groove. The storage cup can conveniently collect the fertilizer after each grinding and crushing, thereby facilitating subsequent extraction and testing.

[0010] Preferably, the grinding head is frustum-shaped. By moving the frustum-shaped grinding head up and down, the gap between the grinding head and the grinding teeth can be changed, thereby changing the grinding fineness of the fertilizer by this device to facilitate subsequent testing.

[0011] Preferably, the outer surface of the grinding head is provided with a spiral groove. The spiral groove can provide a downward squeezing force to the fertilizer particles when the grinding head rotates, thereby facilitating the grinding and pulverizing work.

[0012] Preferably, a number of feed inlets are uniformly fixed on the outer surface of the upper end of the grinding chamber. The fertilizer to be ground and crushed can be conveniently put into the grinding chamber through the feed inlets. Granular fertilizers can be poured directly into the grinding chamber, while block or cake-shaped fertilizers can be crushed by the experimenter before being put in.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. When the threaded ring and the second thread are connected, the base plate and the connecting rod can act as an outer shell and be fitted onto the outer surface of the entire grinding chamber. This can significantly reduce the overall volume of the device. The device is small in size and can be easily folded for easy carrying, transfer and storage. It can adapt to the needs of rapid switching between laboratory and field scenarios and can be more convenient for small-scale crushing and sampling in the laboratory.

[0015] 2. This utility model can drive the movable frame to move downward by rotating the sleeve in conjunction with the threaded sleeve, screw and thread. This will drive the grinding head to move up and down, which can change the gap between the grinding head and the grinding teeth. This can change the grinding fineness of the fertilizer by this device. Attached Figure Description

[0023] 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.

[0024] Please see Figure 1-6 This utility model provides a technical solution: A fertilizer testing processing device includes a grinding chamber 1, inside which a grinding mechanism is installed. This grinding mechanism includes a movable frame 2, a motor 3, a transmission rod 4, a grinding head 5, and grinding teeth 19. The movable frame 2 is movably inserted into the upper part of the grinding chamber 1, allowing it to move up and down. The motor 3 is fixedly installed inside the movable frame 2, and the transmission rod 4 is fixedly connected to the power output shaft of the motor 3. The grinding head 5 is fixedly installed at the lower end of the transmission rod 4. Several grinding teeth 19 are evenly distributed at the lower part of the grinding chamber 1. When the motor 3 operates, it drives the transmission rod 4 and the grinding head 5 to rotate continuously, thereby grinding and pulverizing the fertilizer.

[0025] The lower end of the grinding chamber 1 is equipped with a collection mechanism for collecting the crushed fertilizer. This collection mechanism includes a base plate 6, connecting rods 7, a threaded ring 8, a first thread 9, and a second thread 10. The base plate 6 is located at the lower end of the grinding chamber 1. Several connecting rods 7 are evenly fixedly installed around the outer surface of the base plate 6, and a threaded ring 8 is fixedly installed at the upper end of each connecting rod 7. The lower end of the outer surface of the grinding chamber 1 is provided with the first thread 9, and the upper end of the first thread 9 is provided with the second thread 10. The threaded ring 8 can be rotated to connect with either the first thread 9 or the second thread 10 to achieve different functional states.

[0026] The upper end of the grinding chamber 1 is equipped with an adjustment mechanism for adjusting the position of the grinding head 5. This adjustment mechanism includes a fixed ring 11, a rotating sleeve 12, a threaded sleeve 13, and a screw 14. A fixed ring 11 is fixedly installed in the middle of the upper end of the grinding chamber 1. The rotating sleeve 12 is movably mounted inside the fixed ring 11 via a bearing, allowing the threaded sleeve 13 to rotate around the fixed ring 11, but without relative displacement. The threaded sleeve 13 is fixedly installed at the upper end of the rotating sleeve 12, and the screw 14 is fixedly installed at the upper end of the movable frame 2. The threaded sleeve 13 is screwed onto the outer surface of the screw 14. By rotating the rotating sleeve 12, in conjunction with the threaded sleeve 13, the screw 14, and the thread, the movable frame 2 can be driven to move downwards, thereby causing the grinding head 5 to move up and down, changing the gap between the grinding head 5 and the grinding teeth 19, and thus adjusting the fineness of the fertilizer grinding.

[0027] The outer surface of the rotating sleeve 12 is provided with anti-slip grooves, which makes it convenient for operators to rotate the rotating sleeve 12 and improves the convenience and stability of operation.

[0028] A groove 15 is provided in the middle of the upper end of the base plate 6. A storage cup 16 is movably engaged inside the groove 15 to facilitate the collection of fertilizer after each grinding and crushing, which is convenient for subsequent extraction and testing.

[0029] The grinding head 5 is designed as a frustum. By moving it up and down, the gap between the grinding head 5 and the grinding teeth 19 can be changed, thereby changing the grinding fineness of the fertilizer to meet different testing requirements.

[0030] The outer surface of the grinding head 5 is provided with a spiral groove 17. When the grinding head 5 rotates, it can give the fertilizer particles a downward squeezing force, which promotes the fertilizer particles to enter the space between the grinding head 5 and the grinding teeth 19 under the action of gravity and the transmission of the spiral groove 17, thereby improving the grinding and pulverizing effect.

[0031] Several feed inlets 18 are evenly fixed on the outer surface of the upper end of the grinding chamber 1, making it convenient to put fertilizers that need to be ground and crushed into the grinding chamber 1. Granular fertilizers can be poured directly into the grinding chamber 1, while block or cake-shaped fertilizers can be crushed by the experimenter before being put in.

[0032] Working principle: When using this device, the grinding mechanism and the collecting mechanism are connected via a threaded ring 8, a first thread 9, and a second thread 10. When the threaded ring 8 and the first thread 9 are connected, as... Figure 1 As shown, at this time, the base plate 6 and connecting rod 7 can act as supports, facilitating the overall grinding of the device. Figure 2 As shown, when the threaded ring 8 and the second thread 10 are connected, the base plate 6 and the connecting rod 7 can act as a shell and be fitted onto the outer surface of the entire grinding chamber 1. At this time, the storage cup 16 is fitted onto the outer surface of the rotating sleeve 12. This can significantly reduce the overall volume of the device. The device is small and easy to fold, making it convenient to carry, transfer and store. It can adapt to the needs of rapid switching between laboratory and field scenarios and is more convenient for small-scale crushing and sampling in the laboratory.

[0033] The crushing principle of this device is as follows: The motor 3 drives the transmission rod 4 and grinding head 5 to rotate continuously. During the rotation of the grinding head 5, the spiral groove 17 applies a downward compressive force to the fertilizer particles, causing them to enter the space between the grinding head 5 and the grinding teeth 19 under the influence of gravity and the transmission effect of the spiral groove 17. As the gap between the grinding head 5 and the grinding teeth 19 gradually narrows, the fertilizer particles are slowly ground and crushed to a predetermined fineness as they pass through this space. Simultaneously, by rotating the sleeve 12, in conjunction with the threaded sleeve 13, screw 14, and the threaded drive movable frame 2 moving downwards, the grinding head 5 moves up and down, changing the gap between the grinding head 5 and the grinding teeth 19. This allows for flexible adjustment of the fertilizer grinding fineness, meeting the requirements for fertilizer fineness in different testing scenarios.

[0034] The fertilizer testing processing device of this utility model, through its reasonable structural design and innovative functional settings, is more suitable for laboratory use when carried out and for small-batch sample pulverization.
