AI Technical Summary
[0003]然而这类扦样器在旋转操作时，需要比较高的配合度，如果相对旋转度过小或过大则不能够有效的取样，操作存在一定的弊端，同时也不便于进行分层取样，因此我们基于扦样器的取样原理以及上述缺陷，提出一种玉米果穗扦样器
[0011]在扦样器使用时，人们先双手握持U形把手的横向端两侧，然后将扦样器竖向插入玉米果穗中，直至完全将扦样器插入后，人们便用双手将横向拉把向U形把手的横向端共同握持，使得横向拉把向上靠近U形把手的横向端，将弹簧弹性拉伸，此时内杆的开口腔室上侧将运动至与空心外杆的贯通口相对应，如此一来，玉米果穗便能够通过贯通口往下进入至开口腔室内，人们再松开横向拉把，在弹簧的弹性回弹下，扦样器回到初始装态重新封闭，最后人们握持U形把手将扦样器取出即可完成玉米果穗的在各深度下的取样。

Abstract
Description
Technical Field
[0001] This utility model belongs to the field of sampler technology, specifically relating to a corn ear sampler. Background Technology
[0002] A sampler is a tool used for sampling, typically for taking samples from stored seeds. Samplers are widely used in the grain industry, such as for wheat, corn, rice, and millet, to quickly determine moisture content. Existing manual samplers generally consist of an inner tube and an outer tube. The outer tube has a through hole, while the inner tube has a hollow chamber. By rotating the outer and inner tubes, the through hole is aligned with the hollow chamber to complete the sampling.
[0003] However, this type of sampler requires a high degree of coordination during rotation. If the relative rotation is too small or too large, it cannot effectively sample, which has certain drawbacks. It is also not convenient for stratified sampling. Therefore, based on the sampling principle of the sampler and the above-mentioned defects, we propose a corn ear sampler. Utility Model Content
[0004] The purpose of this invention is to provide a corn ear sampler to solve the problems existing in the background art.
[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows: A corn ear sampler includes a hollow outer rod and an inner rod slidably sleeved inside the hollow outer rod. The lower end of the hollow outer rod is connected and fixed to the inner rod by a spring. The inner rod has a plurality of equally spaced open chambers from top to bottom. The hollow outer rod has a plurality of equally spaced through openings from top to bottom. At the initial length of the spring, each of the open chambers is located above the other open chamber. An inverted U-shaped handle is installed between the two sides of the upper end of the hollow outer rod. A square rod is fixed to the upper end of the inner rod. A square positioning hole is opened at the horizontal end of the U-shaped handle. The square rod is slidably installed with the square positioning hole. A horizontal pull handle is fixedly connected to the square rod.
[0006] As a further limitation of the present utility model, the inner rod and the hollow outer rod together include a limiting component, the limiting component including: a limiting groove, a slider and a longitudinal connecting rod, the limiting groove being opened inside the upper end of the inner rod, the slider being slidably connected to the limiting groove, the longitudinal connecting rod being installed and fixed to the bottom of the hollow outer rod, and the upper end of the longitudinal connecting rod sliding upward through the interior of the inner rod and being connected and fixed to the slider.
[0007] As a further limitation of the present invention, the lower end face of each of the opening chambers is machined into an inclined surface and the lower side is the opening side of the opening chamber. The hollow outer rod is provided with a discharge port corresponding to the opening side of the opening chamber, and a plug is installed on the discharge port.
[0008] As a further limitation of the technical solution of this utility model, the bottom of the hollow outer rod is also processed into a pointed cone shape.
[0009] As a further limitation of the present invention, the two sides of the horizontal pull handle are slidably installed with the two sides of the U-shaped handle.
[0010] As a further limitation of the present invention, the lateral side of the U-shaped handle and the surface of the lateral pull handle are both covered with sponge pads.
[0011] When using the sampler, first hold both sides of the horizontal end of the U-shaped handle with both hands, then vertically insert the sampler into the corn cob until it is fully inserted. Then, hold the horizontal pull handle together towards the horizontal end of the U-shaped handle, so that the horizontal pull handle moves upward and close to the horizontal end of the U-shaped handle, stretching the spring elastically. At this time, the upper side of the opening chamber of the inner rod will move to correspond to the through-hole of the hollow outer rod. In this way, the corn cob can enter the opening chamber through the through-hole. Then, release the horizontal pull handle. Under the elastic rebound of the spring, the sampler returns to its initial position and closes again. Finally, hold the U-shaped handle and remove the sampler to complete the sampling of the corn cob at various depths. Attached Figure Description
[0012] This utility model can be further illustrated by the non-limiting embodiments given in the accompanying drawings.
[0013] Figure 1 This is a structural diagram of the present invention before use; Figure 2 This is a cross-sectional structural diagram of the present invention before use; Figure 3 This is a cross-sectional structural diagram of the present invention when sampling is performed after insertion; The symbols for the main components are explained below: Hollow outer rod 100, spring 101, through port 102, U-shaped handle 103, inner rod 110, open mouth chamber 111, square rod 112, horizontal pull handle 113, limiting groove 114, slider 115, longitudinal connecting rod 116, discharge port 120, plug 121, sponge pad 130. Detailed Implementation
[0014] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.
[0015] Example: Please see Figures 1 to 3 The corn ear sampler shown includes a hollow outer rod 100 and an inner rod 110 slidably sleeved inside the hollow outer rod 100. The lower end of the hollow outer rod 100 and the inner rod 110 are connected and fixed by a spring 101. The inner rod 110 has a plurality of equally spaced open mouth chambers 111 from top to bottom. The hollow outer rod 100 has a plurality of equally spaced through openings 102 from top to bottom. At the initial length of the spring 101, each open mouth chamber 111 is located above the other open mouth chamber 111. An inverted U-shaped handle 103 is installed between the two sides of the upper end of the hollow outer rod 100. A square rod 112 is fixedly installed at the upper end of the inner rod 110. A square positioning hole is opened at the lateral end of the U-shaped handle 103. The square rod 112 is slidably installed with the square positioning hole. A horizontal pull handle 113 is fixedly connected to the square rod 112.
[0016] Before using the sampler, such as Figure 1 and Figure 2 As shown, at this time, under the elastic tension of the spring 101, the opening chamber 111 of the inner rod 110 is positioned below the through-hole 102 of the hollow outer rod 100, thus sealing the space between the inner rod 110 and the hollow outer rod 100. When using the sampler, people first hold both sides of the horizontal end of the U-shaped handle 103 with both hands, then vertically insert the sampler into the corn cob until it is fully inserted. Afterwards, people use both hands to grip the horizontal pull handle 113 towards the horizontal end of the U-shaped handle 103, causing the horizontal pull handle 113 to move upwards towards the horizontal end of the U-shaped handle 103, elastically stretching the spring 101, so that the sampler is positioned as shown in the image. Figure 3 In this state, the upper side of the opening chamber 111 of the inner rod 110 will move to correspond with the through opening 102 of the hollow outer rod 100. In this way, the corn ear can enter the opening chamber 111 through the through opening 102. Then, people release the horizontal pull handle 113. Under the elastic rebound of the spring 101, the sampler returns to the initial state and closes again. Finally, people hold the U-shaped handle 103 to take out the sampler to complete the sampling of the corn ear at various depths. It should also be noted that the positioning fit between the square rod 112 and the square positioning hole enables the hollow outer rod 100 and the inner rod 110 to maintain vertical movement stability, while the inner rod 110 will not deflect relative to the hollow outer rod 100.
[0017] Please continue reading. Figure 2 and Figure 3 To maintain the longitudinal sliding position between the inner rod 110 and the hollow outer rod 100, further structural optimizations were made, namely: The inner rod 110 and the hollow outer rod 100 share a limiting assembly, which includes a limiting groove 114, a slider 115, and a longitudinal connecting rod 116. The limiting groove 114 is opened inside the upper end of the inner rod 110. The slider 115 is slidably connected to the limiting groove 114. The longitudinal connecting rod 116 is fixedly installed at the bottom of the hollow outer rod 100. The upper end of the longitudinal connecting rod 116 slides upward through the interior of the inner rod 110 and is fixedly connected to the slider 115.
[0018] like Figure 2 As shown, before the sampler is used, the slider 115 of the longitudinal connecting rod 116 is at the top of the limiting groove 114. When the inner rod 110 is pulled to take a sample, as... Figure 3 As shown, the slider 115 of the longitudinal connecting rod 116 will be at the bottom of the limiting groove 114, so that the inner rod 110 and the hollow outer rod 100 can be longitudinally positioned.
[0019] Please continue reading. Figures 1 to 3 To facilitate the discharge of corn ears from each of the opening chambers 111, the following structural design is made: Each open mouth chamber 111 has its lower end face machined into an inclined surface, with the lower side being the opening side of the open mouth chamber 111. The hollow outer rod 100 is provided with a discharge port 120 corresponding to the opening side of the open mouth chamber 111, and a plug 121 is installed on the discharge port 120.
[0020] The purpose of machining the lower end face of the open chamber 111 as an inclined surface is to guide the corn ears inside the open chamber 111. When sampling, the outlet 120 is blocked with the plug 121. When it is necessary to remove the corn ears from each open chamber 111, the plug 121 is removed to open the outlet 120. Since the outlet 120 corresponds to the opening side of the open chamber 111, the corn ears can flow out through the guide of the inclined surface. This makes it easy to discharge the corn ears from the open chamber 111. At the same time, in this embodiment, the connection between the plug 121 and the outlet 120 can be a threaded connection to facilitate the screwing in and unscrewing out of the plug 200.
[0021] Please see Figures 1 to 3 As a functional optimization design for this embodiment, namely: The bottom of the hollow outer rod 100 is also machined into a pointed cone shape; this design allows the hollow outer rod 100 to enter the corn cob more effortlessly. The horizontal pull handle 113 is slidably installed on both sides of the U-shaped handle 103; this design can position the horizontal pull handle 113 and maintain the stability of the overall device. The lateral sides of the U-shaped handle 103 and the surface of the lateral pull handle 113 are covered with sponge pads 130; the sponge pads 130 make people more comfortable during operation.
[0022] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
