technical field

The utility model belongs to the technical field of soil sampling machinery and relates to a novel soil sampler.

Background technique

Soil is the basic environmental element that constitutes the ecosystem and the material basis for the survival and development of human beings. Soil testing is an important guarantee for the quality and safety of agricultural products, and soil sampling is a necessary prerequisite for soil testing. As an indispensable tool in the process of soil sample collection, soil sampler directly affects the efficiency of soil collection. During the implementation of projects such as national soil testing and formula fertilization, census of agricultural product origin, and improvement of arable land fertility, a large number of soil samples (generally topsoil, with a sampling depth of 0-20 cm) need to be collected for testing, and it is necessary to improve soil sampling efficiency.

At present, commonly used soil samplers can be divided into mechanical samplers and manual samplers. Among them, the mechanical soil sampler is mainly composed of soil scraping device, bayonet nut, bearing, drill bit and power drive device. It also needs to be equipped with power resources, which has many limitations; while the manual soil sampler is mainly composed of handles, connecting rods, soil reservoirs, sampling pedals and sample unloading handles. Although the structure is relatively simple, it is also easy to carry and carry, but the sampling process It is laborious and time-consuming, and it is inconvenient to take soil, and there are certain limitations. Therefore, it is imperative to develop a new soil sampler with simple structure, easy operation, labor-saving and time-saving, and high sampling efficiency.

detailed description

The principles and features of the present utility model are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the utility model, and are not used to limit the scope of the utility model.

Referring to Fig. 1 and Fig. 2, a new type of soil sampler includes a soil extractor 1, a pedal 2, a frame 3, a telescoping rod 4 and a handle 5, and the pedal 2 is connected to the frame 3 below. In this embodiment, the pedal 2 is rotatably connected to the bottom of the frame 3 . When in use, the pedal 2 is rotated to be perpendicular to the frame 3, so that the user steps on the pedal 2 vertically (relative to the ground) with the foot, and forces the earth taker 1 to be vertical (relative to the ground) The ground at the location) is inserted into the soil; when the use is over or not in use, turn the pedal 2 to be level with the frame 3 for easy storage. The bottom end of foot pedal 2 is fixedly connected with earth taker 1 by thread, is convenient to install and disassemble, and earth taker 1 can be replaced at any time. The top of the frame 3 is fixedly connected with the bottom end of the telescopic rod 4, and the telescopic rod 4 is used to set different grip heights of the handle 5, which is beneficial to users of different heights. The top end of the telescopic rod 4 is fixedly connected with the handle 5, and the handle 5 is used to quickly extract the earth taker 1 from the soil. The soil fetcher 1 is in a semi-closed structure and is used to take soil quickly and conveniently. When in use, at first, the telescopic rod 4 is fixed to a certain length, which meets the height of the user's hand; secondly, the user holds the handle 5 with his hands, steps on the pedal 2 to make the earth taker 1 vertically inserted into the soil, and then Take the foot away from the pedal 2; finally, the user grabs the handle 5 or the telescopic rod 4 and pulls it up, pulls the earth taker 1 out of the soil, and takes out the sampled soil. The handle is of wooden structure with a length of 18cm-20cm.

The telescopic rod 4 includes an outer rod 41 and an inner rod 42. The inner rod 42 is embedded in the outer rod 41. One side of the outer rod 41 is provided with a row of limiting holes 411, and the outer side of the lower part of the inner rod 42 is provided with a matching hole 411. The limit protrusion 421. According to the height of the user and the customary height, the up and down adjustment of the limit projection 421 is placed in the position of the limit hole 411, the length of the telescopic rod 4 can be adjusted, and it can be used after being adjusted to the length that the user needs to adjust.

The semi-closed structure of the earth taker 1 is that a groove body 6 is opened on the earth taker 1 . Not only can the earth taker 1 be quickly inserted into the soil, so that the user saves effort when stepping on the pedal 2, but also can conveniently and quickly push out the taken soil from the earth taker 1, which greatly improves the efficiency of earth taking. The length of the soil fetching device 1 is 21cm～25cm, and the length of the tank body 6 is 20cm. Generally speaking, the length of the tank body 6 is slightly less than the length of the earth taker 1 . Able to get 0cm ~ 20cm deep soil. Collect 15-20 sample points, and the soil mass is about 1-1.5kg. The lower end of the earth taker 1 is an inclined cut surface, so that the earth taker 1 is easily inserted into the soil. The tank body 6 is located at the highest point of the inclined section end, which is conducive to the vertical insertion of the earth taker 1 into the soil.
