Description

Technical Field

[0001] This utility model belongs to the field of wheat seed measurement technology, and in particular relates to a device for measuring the bulk density of wheat seeds using the water displacement method. Background Technology

[0002] Bulk density refers to the weight per unit volume. When measuring the bulk density of wheat seeds, the gaps between the seeds can cause measurement errors. The displacement method can avoid the gaps between the seeds, but the sealed wheat seed bags need to be manually immersed in water during the measurement, which makes it difficult to control the immersion depth. A structure that can control the immersion depth of wheat seed bags is proposed. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides a device for measuring the bulk density of wheat seeds using the water displacement method, thus solving the aforementioned problems.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: a device for measuring the bulk density of wheat seeds using the drainage method, comprising a bucket body and further comprising: a water immersion component for controlling the immersion of wheat seeds in water; the water immersion component comprises a sliding frame, a sliding rod, and clamping plates, wherein the sliding frame is slidably connected to the bucket body, the sliding rod is slidably connected to the sliding frame, and clamping plates are symmetrically slidably connected to both sides of the sliding rod.

[0005] Beneficial effects

[0006] This invention provides a device for measuring the bulk density of wheat seeds using the water displacement method, which has the following advantages compared with the prior art:

[0007] The user places the bucket on the scale and the top of the sealed wheat seed bag between the two clamping plates. Then, the user manually rotates the turntable, causing the left-hand screw and the right-hand screw to rotate synchronously. At this time, the clamping plates threaded onto the left-hand and right-hand screws begin to move linearly in opposite directions along their connection with the slide, thus clamping the wheat seed bag. The user then rotates the wheel, causing the screw fixed to its axis to rotate. This screw drives the slide rod threaded onto it to move up and down along its connection with the slide frame, causing the wheat seed bag clamped between the two clamping plates to descend synchronously. When the conical plate... When the water level mark on the wheat seed bag is level with the water level line, stop rotating the wheel. To increase measurement accuracy, the cone plate should be aligned with the upper part of the water level line on the wheat seed bag. At this time, the bottom of the water immersion sensor should be aligned with the bottom of the water level line, thus preventing the wheat seed bag from being over-immersed in water. The user can then start the motor, which will drive the gear fixed to its output shaft to rotate synchronously. This will cause the gear to start driving the rack meshing with it, causing the sliding frame to slide downwards and immerse the wheat seed bag in water. When the water immersion sensor begins to contact the water, it will emit light and provide a voice prompt. At this point, the motor should be turned off to fix the sliding frame. The bottom of the water level line on the wheat seed bag should now be completely submerged in water. The user should then record the reading on the scale. Attached Figure Description

Detailed Implementation

[0013] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0014] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0015] Please see Figures 1-4 According to one embodiment of the present invention, a device for measuring the bulk density of wheat seeds using the water displacement method includes a barrel 101 and further includes:

[0016] Immersion component 2 is used to control the immersion of wheat seeds in water;

[0017] The immersion assembly 2 includes a sliding frame 201, a sliding rod 202, and a clamping plate 203. The sliding frame 201 is slidably connected to the barrel body 101, the sliding rod 202 is slidably connected to the sliding frame 201, and the clamping plates 203 are symmetrically slidably connected to both sides of the sliding rod 202.

[0018] For the above examples, those skilled in the art should know that the implementation of the above technical solutions is not limited to the specific barrel 101 described in the above embodiments. For example, the bottom of the barrel 101 is provided with a drain hole. The purpose of this setting is to facilitate the quick drainage of water from the barrel 101.

[0019] Regarding the above examples, those skilled in the art should know that the implementation of the above technical solutions is not limited to the specific clamping plate 203 described in the above embodiments. For example, the clamping plate 203 is provided with anti-slip rubber strips. The purpose of this setting is to increase the damping of the interaction on it, thereby preventing the wheat seed sealing strip from falling off.

[0020] Specifically, a left-hand lead screw 204 is rotatably connected to the slide rod 202, and the other end of the left-hand lead screw 204 is fixedly connected to a right-hand lead screw 205. The right-hand lead screw 205 is rotatably connected to the slide rod 202.

[0021] Regarding the above examples, those skilled in the art should understand that the implementation of the above technical solutions is not limited to the specific left-hand lead screw 204, right-hand lead screw 205, and lead screw 207 described in the above embodiments. For example, the left-hand lead screw 204, right-hand lead screw 205, and lead screw 207 are selected as lead screws with a self-locking effect. The purpose of this setting is to facilitate the increase of the limiting effect of the slider connected by the thread on it.

[0022] Specifically, the right-hand lead screw 205 and the left-hand lead screw 204 are respectively threaded with clamping plates 203, and one end of the left-hand lead screw 204 is fixedly connected to a turntable 206.

[0023] For the above examples, those skilled in the art should know that the implementation of the above technical solutions is not limited to the specific turntable 206 described in the above embodiments. For example, the turntable 206 should be provided with anti-slip pads. The purpose of this setting is to facilitate the prevention of the turntable 206 from being unable to rotate effectively when there is water on it.

[0024] Specifically, the slide rod 202 is threadedly connected to the lead screw 207, the lead screw 207 is rotatably connected to the slide frame 201, and a rotating wheel 209 is fixedly connected to the top of the lead screw 207.

[0025] Regarding the above examples, those skilled in the art should know that the implementation of the above technical solutions is not limited to the specific lead screw 207 described in the above embodiments. For example, the lead screw 207 can be a reciprocating lead screw. The purpose of this arrangement is that when the slider connected to the thread on the reciprocating lead screw moves to one end, the direction of movement of the slider can be quickly changed by continuing to control the lead screw to rotate in the same direction.

[0026] Specifically, cone plates 307 are symmetrically fixedly connected to both sides of the bottom of the 201, and a water immersion sensor 301 is fixedly connected to any one of the cone plates 307.

[0027] For the above examples, those skilled in the art should know that the implementation of the above technical solutions is not limited to the specific water immersion sensor 301 described in the above embodiments. For example, the bottom of the water immersion sensor 301 should slightly protrude from the cone plate 307. The purpose of this setting is to make the bottom of the water immersion sensor 301 flush with the identification line on the wheat seed sealing tape, thereby accurately controlling the immersion depth of the wheat seed sealing bag.

[0028] Specifically, a limiting rod 302 is fixedly connected to the sliding frame 201, and a sliding cylinder 303 is slidably connected to the limiting rod 302. The two clamping plates 203 are slidably connected to both sides of the sliding cylinder 303.

[0029] For the above examples, those skilled in the art should know that the implementation of the above technical solutions is not limited to the specific limiting rod 302 described in the above embodiments. For example, the limiting rod 302 is provided with a damping rubber strip. The purpose of this setting is to increase the damping of the sliding cylinder 303, so that the sliding cylinder 303 can slide smoothly.

[0030] Specifically, a rack 304 is fixedly connected to one side of the slide frame 201. The rack 304 meshes with a gear 305. The gear 305 is fixedly connected to the output shaft of the motor 306. The motor 306 is fixedly connected to the barrel 101.

[0031] For the above examples, those skilled in the art should know that the implementation of the above technical solutions is not limited to the specific motor 306 described in the above embodiments. For example, the motor 306 should be a motor with multiple adjustable speeds. The purpose of this setting is to facilitate the adjustment of the sliding speed of the slide frame 201 through this setting.

[0032] In this embodiment of the invention, the user places the bucket 101 on a weighing scale and places the top of the sealed wheat seed bag between the two clamping plates 203. Then, the user manually rotates the turntable 206, causing the turntable 206 to synchronously rotate the left-hand lead screw 204 and the right-hand lead screw 205, which are also fixedly connected to it. At this time, the clamping plates 203 threaded onto the left-hand and right-hand lead screws 204 and 205 begin to move linearly towards each other along their connection points with the slide cylinder 303, thus clamping the wheat seed bag between the two clamping plates 203. The user then rotates the rotating wheel 209, causing the rotating wheel 209 to rotate the lead screw 207 fixedly connected to its axis. The lead screw 207 then causes the slide rod 202 threaded onto it to move up and down along its connection point with the slide frame 201, thereby clamping the wheat seed bag between the two clamping plates 203. The scale begins to descend synchronously. When the cone plate 307 is level with the water level mark on the wheat seed bag, the rotating wheel 209 stops rotating. To increase measurement accuracy, the cone plate 307 should be aligned with the upper part of the water level line on the wheat seed bag. At this time, the bottom of the water immersion sensor 301 should be aligned with the bottom of the water level mark, thus preventing the wheat seed bag from being over-immersed in water. At this time, the user can start the motor 306, which will drive the gear 305 fixedly connected to its output shaft to rotate synchronously. The gear 305 will then drive the rack 304 meshing with it, causing the sliding frame 201 to slide downwards and immerse the wheat seed bag in water. When the water immersion sensor 301 begins to contact the water, it will emit light and provide a voice prompt. At this time, the motor 306 will be turned off to fix the sliding frame 201. The area below the water level mark of the wheat seed bag will be completely submerged in water. The user can then record the reading of the scale.

[0033] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0034] The term "fixed connection" as used in this application refers to a connection in which parts or components are fixed without any relative movement. This includes both detachable and non-detachable connections.

[0035] (1) Detachable connection: The components are fixed together using screws, splines, wedges, etc. This type of connection can be disassembled during maintenance without damaging the parts. However, the specifications of the connecting parts used must be correct (such as the length of the bolts, keys, wedges) and properly tightened.

[0036] (2) Non-removable connections: These mainly refer to welding, riveting, and tenon joints. Since disassembly requires forging, sawing, or oxyacetylene cutting for repair or replacement, the parts generally cannot be reused. At the same time, attention should be paid to process quality, technical inspection, and remedial measures (such as correction and polishing) during connection.

[0037] The sliding connection referred to in this application means that the component can slide along a linear trajectory, and the hinge referred to in this application means that the component can rotate along an axial constraint.

[0038] In some cases, the sliding connection and hinge referred to in this application may also be damped, enabling the component to maintain in the desired position.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
