Problems solved by technology

The growth and physiological and ecological characteristics of plants are affected and regulated by temperature changes. Climate warming will inevitably affect individual growth, population distribution, and ecosystem evolution to a large extent. Temperature and sampling analysis of changes in soil organic matter content and soil water content. During the experiment, soil at multiple sampling points needs to be collected. However, most of the existing sampling methods are manually sampled and collected, and the collection efficiency is low. Therefore, we propose A warming device for desert grassland control experiment

Embodiment 1

[0029] see Figure 1 to Figure 8 , the present invention provides a technical solution: a warming device for desert grassland control test, comprising an outer body frame 1, a cultivation frame 7 fixedly installed with cultivation soil at the inner bottom of the outer body frame 1, and openings on both sides of the inner wall of the cultivation frame 7 Sliding groove 8 is arranged, and sampling shell 9 is arranged on the cultivating frame 7, and the sampling mechanism that soil is automatically sampled is arranged in the sampling shell 9, and the sampling mechanism includes the rotating rod 17 that is positioned at the top of the sampling shell 9 inner wall fixed axis rotation connection, The end of the rotating rod 17 is fixedly connected with an eccentric gear 19, and the output shaft of the eccentric gear 19 is fixedly connected with a cylindrical cam 24 at one end away from the rotating rod 17. One side of the plate 23 is provided with a limiting groove and a sliding colum...

Embodiment 2

[0040] Such as Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, on the basis of Embodiment 1, furthermore, the inner wall of the sampling housing 9 is fixedly connected with two sliding rods 6 near the side of the eccentric gear 19, and the training frame 7 is provided with a mounting frame 16, and the surface of the mounting frame 16 is A through hole is provided and is connected with two sliding rods 6 in a limit sliding manner through the through hole. An eccentric gear 20 rotating with a fixed axis is arranged in the mounting frame 16, and the two sliding rods 6 penetrate through the through holes on the surface of the sampling housing 9 away from each other. One end of the eccentric gear 19 is sheathed with a spring 21 , and the eccentric gear 1 19 and the eccentric gear 2 20 mesh with each other.

[0041] One end of the eccentric gear 19 is sheathed with a spring 21 by the slide bar 6, and when the eccentric gear 19 rotates, the eccentric gear 2 ...

Embodiment 3

[0045] Such as Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, on the basis of Embodiment 1 and Embodiment 2, further, the output shaft of the eccentric gear 20 runs through the upper surface of the mounting bracket 16 and is covered with a transmission belt 2 34, and the transmission belt 2 34 is away from the output of the eccentric gear 2 20. One end of the shaft is transmission-connected with a driving mechanism that drives the sampling housing 9 to move. The driving mechanism includes a connecting shaft 32. A limit block is fixedly installed on one side of the inner wall of the sampling housing 9. A through hole is opened on the limit block and passes through the through hole. It is connected with the connecting shaft 32 for fixed axis rotation, and the bottom end of the connecting shaft 32 is fixedly connected with the driving gear 33, the driving gear 33 is located in the sliding groove 8, and the sliding groove 8 is provided with a rack that me...

Abstract

The invention discloses a desert steppe control test warming device which comprises an outer body frame, a culture frame for culturing soil is fixedly mounted at the bottom in the outer body frame, sliding grooves are formed in the two sides of the inner wall of the culture frame, a sampling shell is arranged on the culture frame, and a sampling mechanism for automatically sampling soil is arranged in the sampling shell. The sampling mechanism comprises a rotating rod located at the top of the inner wall of the sampling shell and rotationally connected with a fixed shaft, an eccentric gear I is fixedly connected to the end of the rotating rod, a cylindrical cam is fixedly connected to the end, away from the rotating rod, of an output shaft of the eccentric gear I, and a fixing plate is fixedly installed on the side, close to the cylindrical cam, of the inner wall of the sampling shell; one side of the fixing plate is provided with a limiting groove and is in limited sliding connection with a sliding column through the limiting groove, and the end, away from the fixing plate, of the sliding column is located in a cam groove of the cylindrical cam. The device has the advantages that automatic sampling and collecting are achieved, meanwhile, the collecting efficiency is improved according to temperature changes, and the problems in the background technology are solved.

Description

technical field [0001] The invention relates to the technical field of soil test devices, in particular to a temperature-increasing device for desert grassland control tests. Background technique [0002] Climate largely determines the distribution of plant species and the type of vegetation. The growth and physiological and ecological characteristics of plants are affected and regulated by temperature changes. Climate warming will inevitably affect individual growth, population distribution, and ecosystem evolution to a large extent. Temperature and sampling analysis of changes in soil organic matter content and soil water content. During the experiment, soil at multiple sampling points needs to be collected. However, most of the existing sampling methods are manually sampled and collected, and the collection efficiency is low. Therefore, we propose The utility model relates to a warming device used for desert grassland control experiment. Contents of the invention [0...
