AI Technical Summary
Existing density drills lack a convenient material ejection mechanism, making it inconvenient to completely remove the obtained sample from the device.
A structure comprising a density drill bit, an L-shaped handle, a movable rod, and a ejector plate was designed. By gripping the rod and the L-shaped handle in opposite directions, and using the outriggers in contact with the ground for support, combined with manual stepping on the outriggers, the sample can be automatically ejected.
This allows for convenient sample return, reduces the labor load of the hand-held device, and improves the convenience and efficiency of soil collection.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of bulk density drilling technology, specifically a bulk density drill that facilitates soil extraction. Background Technology
[0002] A bulk density drill is a type of soil column sampling device, primarily used to measure the bulk density of soil, i.e., the mass of soil per unit volume. Bulk density drills rely mainly on manual pressure applied to the drill rod and drill bit to force the drill bit to penetrate deeper into the soil layer and obtain a sample.
[0003] Although the above methods can facilitate sampling, they inevitably have shortcomings in actual use. For example, the device lacks a convenient material ejection mechanism, making it difficult to completely remove the obtained sample from the device. Therefore, a bulk density drill that facilitates soil sampling is proposed to solve the existing problems. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a bulk density drill that facilitates soil extraction, solving the problem that the lack of a convenient material ejection mechanism in the device makes it difficult to completely remove the obtained sample from the device.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a bulk density drill for convenient soil extraction, comprising a bulk density drill bit and an L-shaped handle. Two L-shaped handles are provided, each fixedly mounted on the top of the bulk density drill bit. A movable rod is slidably mounted on the top of the bulk density drill bit, with one end extending into the interior of the drill bit. A material ejector plate is fixedly connected to the end of the movable rod extending into the drill bit. A ring is fixedly connected to the outer surfaces of the two L-shaped handles via a bracket. A mounting seat is rotatably connected to the surface of the ring via a bearing, and two mounting seats are symmetrically arranged. A support leg is rotatably connected between the front and rear sides of the inner cavity of each mounting seat via a bearing.
[0006] Preferably, both sides of the top of the density drill bit are fixedly connected to a slide plate, a slider is slidably connected inside the slide plate, a return spring is fixedly connected between the slider and the slide plate, and the opposite sides of the two sliders are respectively fixedly connected to both sides of the movable rod.
[0007] Preferably, a lower limit stop block for use with the outrigger is fixedly connected to one side of the inner cavity of the mounting base.
[0008] Preferably, the surface of the L-shaped handle at the lateral bend is provided with a plurality of grip grooves at equal intervals.
[0009] Preferably, grips are fixedly connected to both sides of the movable rod.
[0010] Beneficial effects
[0011] This invention provides a bulk density drill for convenient soil extraction. Compared with existing technologies, it has the following advantages: By sliding a movable rod and a material ejection plate within the bulk density drill bit, the soil column in the drill bit can be easily ejected by gripping the handle and L-shaped handle in opposite directions, causing the material ejection plate to automatically eject the soil column from the drill bit. Furthermore, support legs are provided on both sides of the ring, allowing the handle and L-shaped handle to be gripped in opposite directions, ensuring stable contact with the ground. The entire device is also suspended and supported by manually stepping on the support legs, reducing the labor load on the hand-held device during the material ejection process.

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0017] Please see Figure 1-3 This utility model provides a technical solution: a bulk density drill for easy soil extraction, including a bulk density drill bit 1 and an L-shaped handle 2. Two L-shaped handles 2 are provided, and the two L-shaped handles 2 are respectively fixedly installed on the top of the bulk density drill bit 1. A number of grip grooves 12 are equally spaced on the surface of the lateral bend of the L-shaped handle 2.
[0018] Furthermore, to facilitate the automatic ejection of the soil column, a movable rod 3 is slidably provided on the top of the bulk density drill bit 1, and one end of the movable rod 3 extends into the interior of the bulk density drill bit 1. A material ejection plate 4 is fixedly connected to the end of the movable rod 3 extending into the interior of the bulk density drill bit 1. Slide plates 8 are fixedly connected to both sides of the top of the bulk density drill bit 1. A slider 9 is slidably connected inside the slide plate 8. A return spring 10 is fixedly connected between the slider 9 and the slide plate 8. The opposite sides of the two sliders 9 are fixedly connected to the two sides of the movable rod 3, and a handle 13 is fixedly connected to both sides of the movable rod 3.
[0019] Furthermore, to facilitate easier material unloading, the outer surfaces of the two L-shaped handles 2 are fixedly connected to a ring 5 via a bracket. The surface of the ring 5 is rotatably connected to a mounting base 6 via a bearing. There are two mounting bases 6 symmetrically arranged. The front and rear sides of the inner cavity of the mounting base 6 are rotatably connected to a support leg 7 via a bearing. A lower limit block 11, which is used in conjunction with the support leg 7, is fixedly connected to one side of the inner cavity of the mounting base 6.
[0020] In use, first tilt the support leg 7 upwards to make the density drill bit 1 contact the ground beforehand. Then, hold the two L-shaped handles 2 with both hands, press down and rotate the L-shaped handles 2 to make the density drill bit 1 descend and screw into the soil. After the density drill bit 1 has a soil column inside, use the L-shaped handles 2 to lift the whole device upwards and away from the ground. After the device is lifted, the support leg 7 will rotate downwards to the lowest limit due to gravity. Then, put the support leg 7 on the ground and step on it with both feet to support the height of the density drill bit 1. Then, hold the handle 13 and the L-shaped handle 2 with one hand to make the handle 13 drive the movable rod 3 to descend. The descending movable rod 3 will automatically push out the soil column inside the density drill bit 1 through the ejector plate 4.
