Description

Technical Field

[0001] This utility model relates to the field of black soil protection technology, specifically to a soil formula measurement and testing device for black soil protection. Background Technology

[0002] Black soil is a high-quality and scarce arable land resource with extremely high humus content, high fertility, and good properties. In order to protect black soil resources, it is necessary to measure and test the soil formula. There are various black soil protection soil formula measurement and testing devices on the market.

[0003] For example, the utility model with authorization announcement number CN217931028U discloses a soil formula measurement and testing device for black soil protection, including an installation box. The top of the installation box is snapped with an installation cover plate. A rotating motor is fixedly installed in the middle of the top of the installation cover plate. The rotating motor is powered by an external power source. The bottom of the output shaft of the rotating motor is fixedly connected to a drive shaft. The bottom of the drive shaft is fixedly connected to an installation turntable. This utility model uses an installation tube to drive the lifting slide column and the compaction block to rotate synchronously. Then, the compaction block compacts and refines the soil inside the finer mesh box, so that the refined soil can penetrate the finer mesh box and fall downward. After the compaction block compacts the large soil particles, the compaction block drives the lifting slide column to slide upward against the elastic force of the buffer spring, thereby preventing the finer mesh box from being squeezed and damaged. By refining the soil to be tested, the soil testing effect is effectively improved.

[0004] However, the above technical solutions still have some drawbacks. For example, direct compaction will cause dead leaves to mix into the soil, affecting the screening effect, making it inconvenient to refine the screening, and making it inconvenient to clean the screened impurities. Therefore, we propose a black soil protection soil formula measurement and testing device to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide a soil formula measurement and testing device for black soil protection, in order to solve the problems mentioned in the background art, where direct crushing of existing black soil protection soil formula measurement and testing devices leads to dead leaves being mixed in the soil, affecting the sieving effect, making it inconvenient to refine the sieving, and making it inconvenient to clean the sieved impurities.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a soil formula measurement and testing device for black soil protection, comprising:

The eccentric wheel is symmetrically distributed front and back, and the interior of both the first screening frame and the second screening frame has a porous structure. The holes in the first screening frame are larger than the holes in the second screening frame.

[0010] The first and second screening frames are both provided with a feeding mechanism on their outer sides, wherein the feeding mechanism includes a feeding plate, a connecting rod and a limiting rod, and the feeding plate is rotatably connected to the inner sides of the first and second screening frames.

[0011] Preferably, the front and rear sides of the housing are fixed with a fixing frame, and a motor is symmetrically installed in the middle of the fixing frame, and an eccentric wheel is installed at the output end of the motor.

[0012] Preferably, a first support plate is tightly attached to the top of the eccentric wheel, and the first support plate is fixed on the front and rear sides of the first screening frame and the second screening frame.

[0013] Preferably, a second support plate is fixed to the front and rear sides of both the first screening frame and the second screening frame, and a support spring is installed below the second support plate, with the lower end of the support spring mounted on a fixed frame.

[0014] Preferably, the first screening frame, the feeding plate, and the second screening frame are all internally connected to limit rods via slots, and a connecting rod is integrally provided above the limit rod.

[0015] Preferably, the left and right sides of the connecting rod are rotatably connected to cleaning doors, and the lower interior of the box is connected to a storage box via a slot.

[0016] Compared with the prior art, the beneficial effects of this utility model are: the black soil protection soil formula measurement and testing device can refine the sieving, and screen dead leaves and gravel in the soil separately to ensure the soil testing effect. The sieving effect is good and it is convenient to clean the sieved impurities to ensure the sieving effect.

[0026] 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.

[0027] Please see Figure 1-5 This utility model provides a technical solution: a black soil protection soil formula measurement and testing device, including a box 1, a feeding port 2, a fixing frame 3, a motor 4, an eccentric wheel 5, a first support plate 6, a first screening frame 7, a feeding plate 8, a second support plate 9, a support spring 10, a connecting rod 11, a limiting rod 12, a second screening frame 13, a cleaning door 14, and a storage box 15;

[0028] First, as attached Figure 1 and attached Figure 3As shown, soil is fed into the feeding port 2, which guides the soil into the box 1. The soil falls onto the first screening frame 7. The eccentric wheel 5, the first screening frame 7, the support spring 10, and the second screening frame 13 are combined to form a screening mechanism to screen the soil and separate impurities such as dead leaves and gravel. The feeding plate 8, the connecting rod 11, and the limiting rod 12 are combined to form a feeding mechanism to feed the impurities. The screened soil falls directly into the storage box 15. Specific Implementation

[0029] Existing soil formula measurement and testing devices for black soil protection are inconvenient for separately sieving different impurities. To solve this technical problem, this implementation example is attached. Figure 3 -Appendix Figure 5 As shown, when the motor 4 installed on the fixed frame 3 is opened, the motor 4 drives the eccentric wheel 5 installed at its output end to rotate. The eccentric wheel 5 pushes the first support plate 6 that is tightly attached to its upper end. The first support plate 6 drives the first screening frame 7 and the second screening frame 13, which are integrated inside it, to move. The first screening frame 7 and the second screening frame 13 are symmetrically fixed on the front and rear sides of both sides. The second support plate 9 is installed below the second support plate 9. The support spring 10 pushes the first screening frame 7 and the second screening frame 13 to shake. The first screening frame 7 performs the initial screening of the soil and intercepts dead leaves and other debris in the soil. The second screening frame 13 performs the secondary screening of the soil after the initial screening and intercepts small stones and other debris in the soil. The soil after screening by the second screening frame 13 falls into the storage box 15. Specific Implementation

[0030] Existing soil formula measurement and testing devices for black soil protection are inconvenient for cleaning the screened impurities. To solve this technical problem, this implementation example is attached. Figure 1 Appendix Figure 2 and attached Figure 5 As shown, the cleaning door 14 is rotated on the box 1, and the connecting rod 11 is pulled upward to disengage the limiting rod 12 from the slot connection with the first screening frame 7, the feeding plate 8, and the second screening frame 13. Then, the feeding plate 8 connected to the slot is rotated on the first screening frame 7 and the second screening frame 13. Since the first screening frame 7 and the second screening frame 13 are both inclined, impurities will fall down automatically, making it convenient to collect and clean.
