[0001] This utility model relates to the technical field of soil pulverizing devices, specifically to a soil pulverizing device. Background Technology

[0002] The purpose of soil testing is to comprehensively assess soil quality, monitor pollution levels, guide agricultural production, and protect human health. After soil sampling, the soil sample needs to be pulverized to ensure homogeneity and facilitate subsequent extraction, separation, and analysis. However, existing pulverizing devices are not ideal in their pulverizing effect and are difficult to clean, leaving residues of pulverized soil within the device, which can affect subsequent testing results. Utility Model Content

[0016] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments. These embodiments are implemented under the premise of the technical solution of the present invention. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0017] like Figures 1 to 3As shown, this embodiment of the invention provides a soil pulverizing device, including a base 1. Two support plates 2 are fixed to the upper side of the base 1, and the two support plates 2 are arranged relatively apart. The upper ends of the two support plates 2 are rotatably connected to the outer ends of the rotating shafts 3. Preferably, bearing seats 4 are fixed on the support plates 3, and bearings are fixed inside the bearing seats, fixing the rotating shafts 3 in the inner ring of the bearings. The two rotating shafts 3 are arranged relatively apart, and the inner ends of the two rotating shafts 3 are fixedly connected to both sides of the machine head 5, so that the machine head 5 can rotate together with the rotating shafts 3. A rotating wheel 6 is fixed to the outer end of one of the rotating shafts 3, and the rotating shaft 3 can be rotated by the rotating wheel 6. A motor is fixedly installed inside the machine head 5, and a cup body 7 is detachably fixedly connected to the lower side of the machine head 5. The upper end of the cup body 7 is detachably connected to an inner cover 8, which can be closed onto the upper end of the cup body 7. Inside the cup body 7 is a crushing shaft 9, and several crushing blades 10 are arranged on the outer side of the crushing shaft 9. A through hole is provided in the middle of the upper end of the inner cover 8, and the upper end of the crushing shaft 9 passes through the through hole. A gap is provided between the crushing shaft 9 and the inner side of the through hole. A sealing element can also be installed at the through hole to improve the sealing effect without affecting the rotation of the crushing shaft 9. The lower end of the motor rotor has a slot 11, and the upper end of the crushing shaft 9 is inserted into the slot 11. After the cup body 7 is fixed on the machine head 5, the motor is started, which drives the crushing shaft 9 to rotate, causing the crushing blades 10 to rotate, thus crushing the soil sample inside the cup body 7. During this process, rotating the rotating wheel 6 causes the cup body 7 and the machine head 5 to rotate together, allowing the soil sample to move up and down inside the cup body 7, greatly improving the crushing effect.

[0018] In order to ensure stable rotation of the crushing shaft 9, it is preferable to fix a limiting shaft 12 at the lower end of the cup body 7 and provide a limiting hole 13 at the lower end of the crushing shaft 9. The limiting shaft 12 is inserted into the limiting hole 13 and the crushing shaft 9 is slidably connected to the outside of the limiting shaft 12. Under the action of the limiting shaft 12, the lower end of the crushing shaft 9 can be prevented from moving laterally.

[0019] In this embodiment of the present invention, there are preferably three pulverizing blades 10. The three pulverizing blades 10 are arranged at intervals along the length of the pulverizing shaft 9, and two adjacent pulverizing blades 10 are arranged at 120° intervals, so that the pulverizing blades 10 have good dynamic balance when rotating together with the pulverizing shaft 9.

[0020] To prevent the inner cover 8 from rotating after the machine head 5 is fixedly connected to the cup body 7, a limiting groove 14 is provided at the upper end of the inner cover 8, and a limiting protrusion 15 that mates with the limiting groove 14 is provided at the lower end of the machine head 5. After the machine head 5 is fixed to the cup body 7, the limiting protrusion 15 at the lower end of the machine head 5 is inserted into the limiting groove 14 at the upper end of the inner cover 8. Both the limiting groove 14 and the limiting protrusion 15 are regular polygonal in shape.

[0021] To facilitate fixing the machine head 5 to the cup body 7, it is preferable to provide a fastening assembly 16 on the outer side of the machine head 5 and the cup body 7, thereby fixing the machine head 5 and the cup body 7 together through the fastening assembly 16. After opening the fastening assembly 16, the cup body 7 can be removed. To facilitate the installation of the fastening assembly 16, the upper outer side of the cup body 7 can be made into a rectangle.

[0022] To prevent the power cord of the machine head 5 from becoming tangled when it rotates with the shaft 3, the rotation angle of the machine head 5 needs to be limited. Preferably, a limit rod 17 is fixed to the lower side of the cup body 7, and a limit block 18 is fixed between the lower middle parts of the two support plates 2. The limit block 18 can limit the rotation angle by preventing the limit rod 17 from passing through, but it does not affect the passage of the machine head 5. The limit block 18 can be made of materials such as nylon or rubber to avoid excessive impact force and noise.

[0023] Preferably, multiple support blocks 19 are provided on the lower side of the base 1. The lower end of the support block 19 is made of rubber to provide shock absorption and anti-slip function. The upper end of the support block 19 can be set as a threaded rod and threadedly connected and fixed to the base 1.

[0024] In use, open the latch assembly 16 and remove the cup body 7. After opening the inner cover 8, add an appropriate amount of soil sample into the cup body 7. Then, close the inner cover 8 onto the upper end of the cup body 7. Align the upper end of the crushing shaft 9 with the slot 11, and align the limiting groove 14 on the inner cover 8 with the limiting protrusion 15 at the lower end of the head 5. After the alignment is complete, fix the cup body 7 onto the head 5 using the latch assembly 16. Then, control the motor inside the head 5 to operate and manually rotate the wheel 6 to move the soil sample back and forth inside the cup body, thereby ensuring full contact between the soil sample and the crushing blade 10 and improving the crushing effect. After the crushing process is complete, the cup body 7 can be removed. After removing the soil sample, clean the inside of the cup body 7, the crushing shaft 9, the crushing blade 10, and the inner cover 8 to avoid any residue.

[0025] The above description is merely a preferred embodiment of this utility model. It should be noted that for those skilled in the art, other parts not specifically described are existing technology or common knowledge. Several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
