Description

Technical Field

[0001] This utility model relates to the field of bulk grain sampling, and in particular to a quantitative bulk grain sampling device. Background Technology

[0002] In order to ensure the quality of bulk grain during storage, it is necessary to take samples of the bulk grain at regular intervals and in fixed quantities, and then take the samples for testing to judge the quality of the bulk grain.

[0003] The existing sampling process involves placing a spoon under the corresponding bulk grain container, opening the outlet valve of the container, and using the spoon to collect the bulk grain flowing out of the container. Once a certain amount of bulk grain is collected, the operator removes the spoon and closes the outlet valve of the container. The amount of bulk grain in the spoon is then used as the sampling quantity, or the quantity collected from multiple spoonfuls can be used as the sampling quantity.

[0004] The problem with the existing sampling method is that it is not easy to control the amount of loose grain that is scooped out by the spoon each time. It basically relies on experienced staff to sense the amount of loose grain in the spoon by sight or touch. This experience-based judgment is not accurate and cannot guarantee the accuracy of the sampling quantity. Insufficient or excessive sampling is not conducive to the subsequent testing of the quality of loose grain. Utility Model Content

[0005] The purpose of this invention is to provide a quantitative sampling device for bulk grains to solve the technical problem that spoons cannot perform quantitative sampling in the prior art.

[0006] The technical solution of the bulk grain quantitative sampling device of this utility model is as follows: A bulk grain quantitative sampling device includes a device base, an actuating lever with its axis extending in the front-rear direction hinged to the device base, a grain-taking scoop at the left end of the actuating lever, a lever return spring between the device base and the actuating lever, a bulk grain baffle mounted on the device base above the grain-taking scoop in the left-right direction, the bulk grain baffle having a blocking position that moves to the left to block the upper side of the grain-taking scoop, and a clearance position that moves to the right to move away from the upper end of the grain-taking scoop, a baffle spring between the device base and the bulk grain baffle applying a leftward force to the bulk grain baffle, a baffle positioning groove at the bottom of the bulk grain baffle, and an unlocking mechanism on the device base that cooperates with the baffle positioning groove. When the right end of the grain-taking scoop is tilted upward, the actuating lever drives the unlocking mechanism to unlock the bulk grain baffle, and the bulk grain baffle moves from the clearance position to the blocking position.

[0007] Furthermore, the bottom left end of the bulk grain baffle is provided with a bulk grain baffle that gradually slopes downward from right to left.

[0008] Furthermore, a left-side connecting plate of a spring is provided at the top left end of the bulk grain baffle, and a right-side connecting plate of a spring is provided at the top left end of the device base. The baffle spring is a compression spring located between the left-side connecting plate and the right-side connecting plate of the spring.

[0009] Furthermore, the left side baffle of the spring is used to cooperate with the left end stop of the device seat to limit the rightward movement limit of the bulk grain baffle.

[0010] Furthermore, the device base includes an upper base body, a lower base body, and front and rear side plates disposed on the front and rear sides between the upper base body and the lower base body. There is an installation space between the front and rear side plates. The actuating lever is inserted into the installation space. The actuating lever is hinged to the front and rear side plates through a lever hinge shaft. The grain baffle is guided and moved along the left and right direction and assembled on the upper base body.

[0011] Furthermore, there are multiple lever return springs, which are spaced apart in the front-to-back direction. The lever return springs are located between the bottom of the upper seat and the right end of the actuating lever.

[0012] Furthermore, the unlocking mechanism includes an unlocking lever hinged between the front side plate and the right side plate. The left end of the unlocking lever is provided with a baffle engagement protrusion for engaging with the baffle positioning groove, and the right end of the unlocking lever is provided with a lever engagement protrusion for being pushed upward by the right end of the actuating lever.

[0013] Furthermore, a reset spring for the unlocking mechanism is provided between the upper seat and the unlocking lever.

[0014] The beneficial effects of this technical solution are as follows: During use, the bulk grain baffle moves to the right to the clearance position, the baffle spring stores energy, and the unlocking mechanism cooperates with the baffle positioning groove to position the bulk grain baffle in the clearance position. The bulk grain falls into the grain scoop through the outlet of the bulk grain cylinder. As the amount of bulk grain in the grain scoop increases, the action lever overcomes the force of the lever return spring, and the right end of the action lever swings upward. The action lever drives the unlocking mechanism to release the lock on the bulk grain baffle. Under the action of the baffle spring, the bulk grain baffle moves to the left to the blocking position. The left end of the bulk grain baffle blocks the upper side of the grain scoop, and the bulk grain can no longer fall into the grain scoop, thus ensuring the quantitative grain taking by the grain scoop, eliminating the need for manual experience judgment, and ensuring the accuracy of sampling.

Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0019] The features and performance of this utility model will be further described in detail below with reference to the embodiments.

[0020] An example of an embodiment of the bulk grain quantitative sampling device of this utility model is shown below. Figures 1-6 As shown: It includes a device base, and a handle extending in the front-rear direction is fixed to the rear side of the device base.

[0021] The device base includes an upper base, a lower base, and front and rear side plates disposed on the front and rear sides between the upper and lower bases. There is an installation space between the front and rear side plates. An actuating lever is inserted into the installation space along the left-right direction. The actuating lever is hinged to the front and rear side plates via a lever hinge shaft, the axis of which extends along the front-back direction.

[0022] A grain-taking scoop is provided at the left end of the actuating lever, and a lever return spring is provided between the device base and the actuating lever. In this embodiment, there are multiple lever return springs, which are spaced apart in the front-back direction. The lever return springs are located between the bottom of the upper base and the right end of the actuating lever. By selecting an appropriate number of lever return springs or a lever return spring of an appropriate specification, the amount of grain taken by the grain-taking scoop can be adjusted.

[0023] The upper base has a guide groove extending in the left-right direction. A bulk grain baffle is guided and moved within the guide groove. The bulk grain baffle has a blocking position that moves to the left to block the upper side of the grain-retrieving scoop, and a clearance position that moves to the right to move away from the upper end of the grain-retrieving scoop. A baffle spring is provided between the device base and the bulk grain baffle to apply a leftward force to the bulk grain baffle. In this embodiment, a left-side connecting plate of the spring is provided at the top left end of the bulk grain baffle, and a right-side connecting plate of the spring is provided at the top left end of the device base. The baffle spring is a compression spring provided between the left-side and right-side connecting plates of the spring. The left-side baffle of the spring is used to cooperate with the left end of the device base to limit the rightward movement limit of the bulk grain baffle.

[0024] The right end of the bulk grain baffle is provided with a right-side stop block, which is used to cooperate with the right end of the upper seat to limit the leftward movement limit of the bulk grain baffle.

[0025] The bottom of the bulk grain baffle is provided with a baffle positioning groove, and the device base is provided with an unlocking mechanism that cooperates with the baffle positioning groove. When the right end of the grain scoop is tilted upward, the action lever drives the unlocking mechanism to unlock the bulk grain baffle, and the bulk grain baffle moves from the avoidance position to the blocking position.

[0026] In this embodiment, the unlocking mechanism includes an unlocking lever hinged between the front side plate and the right side plate. The left end of the unlocking lever is provided with a baffle engagement protrusion for engaging with a baffle positioning groove, and the right end of the unlocking lever is provided with a lever engagement protrusion for being pushed upward by the right end of the actuating lever. The unlocking lever is hinged between the front side plate and the rear side plate via the unlocking mechanism hinge shaft.

[0027] An unlocking mechanism return spring is provided between the upper seat and the unlocking lever. The unlocking mechanism return spring is used to apply a downward force to the right end of the unlocking lever.

[0028] When in use, the bulk grain baffle can be moved to the right until it reaches the clearance position, such as... Figure 1 As shown, at this time, the baffle spring is compressed, and the baffle at the left end of the unlocking lever swings upward with the protrusion and extends into the baffle positioning groove at the bottom of the bulk grain baffle, and the bulk grain baffle is positioned in the avoidance position.

[0029] The grain scoop is placed below the outlet of the bulk grain container (which is existing technology and not shown in the accompanying drawings of this utility model). As the bulk grain gradually falls into the scoop, the weight on the left end of the scoop gradually increases. This first overcomes the force of the lever's return spring, causing the right end of the lever to swing upwards. The right end of the lever first contacts the bottom of the lever's engagement protrusion. As the weight on the left end of the scoop continues to increase, the right end of the lever overcomes the combined force of the lever's return spring and the unlocking mechanism's return spring, causing the left end of the unlocking lever to swing downwards. The baffle engagement protrusion disengages from the baffle positioning groove, and the baffle spring quickly releases energy, pushing the bulk grain baffle from the avoidance position to the blocking position, preventing the bulk grain from falling back into the scoop. Figure 3 As shown, the outlet of the bulk grain container is then closed to achieve quantitative acquisition of the quantity of bulk grain by the grain scoop.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. The patent protection scope of the present utility model shall be determined by the claims. Similarly, any equivalent structural changes made based on the description and drawings of the present utility model shall also be included within the protection scope of the present utility model.
