[0020] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0021] Example: Figures 1 to 3 As shown, this utility model discloses a grinding device for soil nutrient testing, including a frame 1. A mortar 4 is installed on the top surface of the frame 1. The top surface of the mortar 4 is open, which facilitates the placement of the soil to be ground in the mortar 4. A discharge port (not shown in the figure) is opened on one side of the mortar 4. A baffle (not shown in the figure) is provided at the discharge port. The discharge port is designed to facilitate the cleaning of residual impurities in the mortar 4. The baffle is a prior art device, and the baffle is connected to the discharge port by a threaded connection, which facilitates disassembly.

[0022] The front of the frame 1 has a cavity 15, and a collection box 2 is slidably arranged in the cavity 15. The bottom surface of the mortar 4 has multiple filter holes 14 evenly distributed. The top surface of the frame 1 has a circular groove that communicates with the cavity 15, and the mortar 4 is fixedly installed in the circular groove.

[0023] The soil ground in the mortar 4 can pass through the filter hole 14 into the collection box 2 in the cavity 15. The top surface of the collection box 2 is open to facilitate the entry of soil. After the soil grinding is completed, the collection box 2 can be directly removed and the soil sample in the collection box 2 can be poured out. The operation is simple and does not require repeated operation. The filter hole 14 is designed so that small soil particles that meet the requirements can enter the collection box 2, while large soil particles that do not meet the requirements can continue to be ground in the mortar 4, which can reduce the amount of soil in the mortar 4 and further improve efficiency and grinding quality.

[0024] A mounting frame 12 is fixedly installed on the back of the frame 1. A motor 10 is installed on the mounting frame 12, and a rotating shaft 6 is fixedly connected to the output end of the motor 10. A grinding roller 5 is fixedly connected to the bottom end of the rotating shaft 6. The grinding roller 5 is located inside the mortar 4. The motor 10 drives the rotating shaft 6 to rotate, and the rotating shaft 6 drives the grinding roller 5 to rotate, so that the grinding roller 5 grinds the soil in the mortar 4 to meet the requirements of nutrient testing.

[0025] The side surface of the grinding roller 5 is in sliding connection with the side surface of the mortar 4, and the bottom surface of the grinding roller 5 is spaced from the inner bottom surface of the mortar 4, and the spacing can be determined according to the size of the soil particles to be ground, for example, the length of the rotating shaft 6 can be determined in advance, so that the soil can be ground finely by the grinding roller 5.

[0026] The cover 9 is slidably arranged on the rotating shaft 6, and the two ends of the cover 9 are fixedly connected with the connecting blocks 11, respectively. The support blocks 3 are symmetrically installed on the two sides of the frame 1, and the screw rods 7 and the sliding rods 8 are arranged between the support blocks 3 and the connecting blocks 11, respectively. By rotating the screw rod 7, the connecting block 11 can be moved, thereby driving the cover 9 to move. When grinding, the cover 9 covers the mortar 4 to prevent dust from flying. The cover 9 is made of transparent bakelite, so that the amount of soil remaining in the mortar 4 can be observed.

[0027] The bottom end of the screw rod 7 is rotatably arranged on one of the support blocks 3, and the top end of the screw rod 7 is threadedly penetrated through one of the connecting blocks 11 and extends to the top of the connecting block 11. The bottom end of the sliding rod 8 is fixedly arranged on the other support block 3, and the other end of the sliding rod 8 is slidably penetrated through the other connecting block 11 and extends to the top of the connecting block 11. The top surfaces of the screw rod 7 and the sliding rod 8 are fixedly installed with the limit plates, respectively. The limit plates facilitate the rotation of the screw rod 7, and the rotation of the screw rod 7 drives one of the connecting blocks 11 to move, thereby driving the cover 9 to move and driving the other connecting block 11 to move along the sliding rod 8, which can play a guiding role.

[0028] The controller 13 is fixedly installed on one side of the frame 1, and the motor 10 is electrically connected with the controller 13. The model of the controller 13 is SC200. The controller 13 can control the start and stop of the motor 10, so that the soil can be ground by the grinding roller 5.

[0029] In operation, the soil is directly put into the mortar 4, and then the screw rod 7 is rotated to drive the connecting block 11 to move the cover 9, so that the top surface of the mortar 4 is covered by the cover 9. The motor 10 is started, and the rotating shaft 6 is driven to rotate by the motor 10, thereby driving the grinding roller 5 to rotate and grind the soil. The ground soil is directly collected into the collecting box 2, and the collecting box 2 can be directly taken out for taking out the soil, which is convenient to operate.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present application and is not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or make equivalent replacements to some technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
