Description

Technical Field

[0001] The utility model relates to the technical field of soil detection, in particular to a screening and processing device for soil detection. Background Art

[0002] The soil screening process required for soil testing is to screen out larger impurities and substances from the soil sample for subsequent soil analysis and testing.

[0003] At present, in the prior art, such as CN212069494U, a screening and processing device for soil detection is disclosed. The screen can make reciprocating up and down movements through transmission, so as to achieve the function of screening the soil. A large amount of soil can be processed at one time, and can be quickly collected by a receiving cup; a fan is added to use wind force to blow away the impurity particles on the screen, avoiding the trouble of manually disassembling the screen. However, when screening the soil, the small branches in the soil have a very small diameter. When the screen is used to screen the soil, the branches will fall vertically and pass through the screen, so that the screened soil is mixed with the branches, resulting in the soil needing to be filtered for multiple times before it can be completely removed, which greatly prolongs the soil screening time and reduces the soil screening efficiency. Therefore, a screening and processing device for soil detection is designed to solve the above-mentioned problems. Utility Model Content

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] For example, see Figure 1-3The present embodiment provides a screening and processing device for soil detection, including a screening box 1, the upper end of the screening box 1 is fixedly connected to the feed hopper 2, a crushing roller 5 is installed in the feed hopper 2, the front part of the crushing roller 5 on one side passes through the feed hopper 2 and is connected to the output end of the second servo motor 4, and the crushing roller 5 can be driven to rotate by the second servo motor 4, so that the crushing roller 5 crushes the soil before screening in the screening box 1, which is convenient for soil screening. A protective plate 11 is fixedly connected to the lower end of the feed hopper 2, so that the crushed soil is closer to the middle, which is conducive to the spoiler 64 to guide the soil, and a discharge pipe 3 is fixedly connected to the lower end of the screening box 1, and an inclined screening net 12 is fixedly connected to the bottom end of the screening box 1, and a discharge port 13 is arranged at the lower end of the screening net 12 to facilitate the removal of impurities.

[0018] When the screening box 1 is used to screen the soil, if branches mixed in the soil fall vertically, some branches will pass through the screening net 12, so that the screened soil is still mixed with these branches. Therefore, in order to reduce the number of soil screening times, a mounting frame 6 is installed in the middle of the screening box 1, and a spoiler 64 is fixedly connected in the mounting frame 6, so that the spoiler 64 can divert the soil and mixed branches to prevent the branches from falling vertically.

[0019] In actual use, the sparse and broken soil will directly fall on the installation frame 6 and the upper end of the spoiler 64 and accumulate. If it is not cleaned, it will cause blockage and affect the screening of the soil. Therefore, springs 61 are fixedly connected to the lower ends of both sides of the installation frame 6, and the lower ends of the springs 61 are fixedly connected to the fixing plates 62. The two sides of the fixing plates 62 are fixedly connected to the side walls of the screening box 1. The two sides of the upper end of the installation frame 6 are fixedly connected to the pressure plates 7. The pressure plates 7 can be driven to descend, so that the pressure plates 7 drive the installation frame 6 to descend, and the springs 61 can be used to drive the installation frame 6 to recover, so that the installation frame 6 moves up and down, thereby shaking off the soil on the upper surface to avoid accumulation.

[0020] Specifically, in order to facilitate the pressure plate 7 to drive the installation frame 6 to move, it is fixedly connected to the No. 1 servo motor 8 through the motor box on one side of the screening box 1, and the rotating rod 9 is fixedly connected to the output end of the No. 1 servo motor 8. The rotating rod 9 is rotatably connected to the side wall of the screening box 1 away from the side of the No. 1 servo motor 8, and the pressure plates 10 are fixedly connected on both sides of the rotating rod 9.

[0021] The rotating rod 9 is driven to rotate by the No. 1 servo motor 8, so that the rotating rod 9 drives the pressure plate 10 to rotate. When the pressure plate 10 rotates to the bottom, it will squeeze the pressure plate 7, and the pressure plate 7 drives the installation frame 6 to descend.

[0022] Specifically, a telescopic rod 63 is fixedly connected to the upper end of the fixed plate 62, and the upper end of the telescopic rod 63 passes through the middle of the spring 61 and is fixedly connected to the mounting frame 6. The telescopic rod 63 structure can prevent the spring 61 from tilting. Although the mounting frame 6 and the screening box 1 are compatible, if the spring 61 is not limited, the spring 61 can only shrink up and down, which will cause the mounting frame 6 to hit the screening box 1 and cause more wear on the inner wall of the screening box 1. Therefore, the telescopic rod 63 is set to limit the spring 61, reduce the shaking tendency of the mounting frame 6, and facilitate use.

[0023] When the utility model is used, soil blocks are put into the screening box 1 from the feed hopper 2, and the No. 1 servo motor 8 and the No. 2 servo motor 4 are started. The No. 2 servo motor 4 drives the crushing roller 5 to rotate, so that the crushing roller 5 crushes the soil blocks, which is convenient for subsequent soil screening. The crushed soil blocks pass through the spoiler 64 on the mounting frame 6, and the small branches mixed in the soil also pass through the spoiler 64, and are guided by the spoiler 64 when passing through, so that the branches cannot pass vertically, and the branches can only fall down obliquely and fall on the screening net 12, avoiding vertical falling through the screening net 12, and the soil passes through the screening net 12. The net 12 flows out from the discharge pipe 3, and the screened branches and other debris flow out from the discharge port 13 along the screening net 12. At the same time, the No. 1 servo motor 8 drives the rotating rod 9 to rotate, so that the rotating rod 9 drives the pressure plate 10 to rotate. When the pressure plate 10 rotates to the bottom, it will squeeze the pressure plate 7, and the pressure plate 7 drives the mounting frame 6 to descend. The mounting frame 6 will squeeze the spring 61 to contract. When the pressure plate 10 rotates to the top, the spring 61 will drive the mounting frame 6 to recover. The reciprocating rising and falling mounting frame 6 will shake off the soil on the mounting frame 6 and the spoiler 64 to avoid accumulation, which is convenient for screening the soil.
