Technical Field

[0001] This utility model relates to the field of soil collection technology, specifically a soil collection device for rapeseed rhizosphere soil. Background Technology

[0002] Rapeseed, also known as European rapeseed, is an annual or biennial herb belonging to the Brassicaceae family. Native to Europe, it is widely cultivated worldwide and is one of the major oilseed crops. Due to its high economic benefits, the planting area of ​​rapeseed has been continuously expanding. However, with the accumulation of planting years and the gradual increase in the amount of chemical fertilizers used in greenhouse cultivation, soil problems in continuous cropping of rapeseed in greenhouses are becoming increasingly serious, gradually becoming a major bottleneck restricting further increases in rapeseed yield. To improve the planting efficiency of rapeseed, it is necessary to conduct soil sampling and testing of the rhizosphere soil.

[0003] The root shaking method is commonly used to collect rhizosphere soil from rapeseed. In the traditional collection process, this method requires manual operation by staff, which is laborious and slow, reducing the efficiency of soil collection. Furthermore, during the root shaking process, the rhizosphere soil is easily scattered, resulting in less rhizosphere soil being collected. This not only pollutes the environment and wastes soil samples, but also increases the workload of staff. Therefore, we need to propose a soil collection device for rapeseed rhizosphere soil.

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.

[0022] Please see Figure 1-4 This utility model provides a soil sampling device for rapeseed rhizosphere soil, including a box body 1. The top of the box body 1 is connected to a box cover 2 via a hinge. A vibration component 3 for rapeseed rhizosphere soil detachment is installed on the side wall of the box body 1. A placement groove 4 is opened at the bottom of the box body 1. A collection box 5 for collecting rhizosphere soil is slidably connected to the inner cavity of the placement groove 4. A filter plate 6 is provided in the inner cavity of the box body 1. A retaining ring 7 for limiting the movement range of rapeseed rhizosphere soil is provided on the upper surface of the filter plate 6. An active component 8 for assisting the up-and-down vibration of the filter plate 6 is installed on the top of the filter plate 6. When the box cover 2 is opened, rapeseed is placed on the filter plate 6 in the box body 1 and the vibration component 3 is activated to vibrate the filter plate 6, causing the rapeseed rhizosphere soil to detach. With the assistance of the active component 8, the filter plate 6 vibrates, so that the detached rhizosphere soil falls into the collection box 5 through the filter holes on the filter plate 6 for collection. This reduces the workload of the staff and improves the efficiency of rhizosphere soil collection.

[0023] The vibration assembly 3 includes a stepper motor 31, which is fixedly connected to the side wall of the housing 1 via a mounting plate. The output shaft of the stepper motor 31 passes through the housing 1 and is fixedly connected to a rotating rod 32. The rotating rod 32 is located in the inner cavity of the housing 1, and the other end of the rotating rod 32 is rotatably connected to the inner side wall of the housing 1. A rotating block 33 is provided on the outer surface of the rotating rod 32, and the outer surface of the rotating block 33 is in contact with the lower surface of the filter plate 6. The stepper motor 31 is started to provide driving force to drive the rotating rod 32 to rotate, and the rotating rod 32 drives the rotating block 33 to rotate, thereby causing the filter plate 6 to vibrate.

[0024] The rotating block 33 is elliptical in shape. There are two sets of rotating blocks 33, which are located at both ends of the rotating rod 32. The arrangement of the rotating blocks 33 improves the smoothness of the rotating blocks 33 when moving the filter plate 6.

[0025] The movable component 8 includes a fixed block 81 with a through hole at its center. A movable rod 82 is inserted and slidably inserted into the inner cavity of the through hole. The bottom end of the movable rod 82 is fixedly connected to the upper surface of the filter plate 6, and the top end of the movable rod 82 is fixedly connected to a limit block 83. There are four sets of fixed blocks 81, which are symmetrically distributed around the inner side wall of the box 1. The movable rod 82 and the fixed blocks 81 work together to assist the filter plate 6 in moving up and down, thereby removing the soil from the rapeseed rhizosphere.

[0026] A spring 9 is fitted on the outer surface of the movable rod 82. The spring 9 is located between the fixed block 81 and the filter plate 6. The spring 9 is used to vibrate the filter plate 6. The spring 9's rebound force drives the filter plate 6 to reset, thereby increasing the vibration effect.

[0027] Both sides of the collection box 5 are fixedly connected with sliders 10. The inner side wall of the box body 1 is provided with a groove 11 corresponding to the slider 10. The surface of the slider 10 is slidably connected to the inner cavity of the groove 11. Through the cooperation of the slider 10 and the groove 11, the collection box 5 can slide in the inner cavity of the box body 1, which facilitates the collection of rapeseed rhizosphere soil by the staff.

[0028] A slot is provided on one side of the top of the box 1. An acrylic plate 12 is embedded in the inner cavity of the slot. The acrylic plate 12 is transparent, which makes it convenient for staff to collect the soil around the rapeseed roots from the outside.

[0029] A rubber ring 13 is provided on the inner wall of the box cover 2. One end of the rubber ring 13 is attached to the inner wall of the box body 1. The sealing ring makes the box body 1 sealed, preventing the soil from scattering around the roots.

[0030] In practical use, open the box cover 2, place the rapeseed on the filter plate 6, and then close the box cover 2. Start the stepper motor 31 to drive the rotating rod 32 to rotate, causing the rotating blocks 33 at both ends of the rotating rod 32 to rotate and drive the vibrating plate to vibrate. When the filter plate 6 vibrates, the movable rod 82 and the fixed block 81 assist the filter plate 6 to move up and down. The spring 9 increases the vibration effect of the vibrating plate, causing the rapeseed root soil on the rapeseed to fall off when the vibrating plate vibrates. The fallen rapeseed root soil then falls into the collection box 5 through the filter holes on the filter plate 6. The staff then picks up the collection box 5 to collect the rapeseed root soil. The acrylic plate 12 allows the staff to observe the rapeseed root soil collection process from the outside. Due to the sealing ring, the box cover 2 is sealed with the box body 1 when closed, preventing the rapeseed root soil from scattering, thereby reducing the workload of the staff, improving the efficiency of root soil collection, avoiding environmental pollution, and avoiding waste of soil samples.
