Description

Technical Field

[0001] This utility model relates to the field of feed processing and testing technology, and in particular to a rapid metering device for multi-stage screening of feed particle size. Background Technology

[0002] Feed particle size refers to the size and distribution of various particles in feed. Feed particle size has a significant impact on the mechanical properties, flowability, nutritional composition, and feeding effectiveness of feed. Appropriate particle size can improve animals' feed intake, digestion, and utilization, reduce feed costs, and increase farming efficiency. Therefore, in feed production and processing, particle size and distribution should be rationally controlled according to the characteristics and needs of animals.

[0003] During feed processing, it is necessary to test the particle size distribution of the feed. Some existing feed processing methods require specialized screening equipment to test the particle size distribution, which is not only cumbersome to operate but also time-consuming, and cannot meet the need for timely measurement and testing of the particle size distribution of feed. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing feed processing methods that require specialized screening equipment to detect particle size distribution, which is not only cumbersome to operate but also time-consuming and cannot meet the need for timely measurement and detection of feed particle size distribution. This invention provides a rapid metering device for multi-stage screening of feed particle size.

[0005] The purpose of this utility model is achieved through the following technical solution: a rapid metering device for multi-stage screening of feed particle size, including a box body, a sampling chamber is provided inside the box body, and multiple screening chambers located inside the box body are provided on one side of the sampling chamber, and a sieve plate is installed between two adjacent screening chambers, and the sieve hole diameter on the multiple sieve plates decreases sequentially.

[0006] The inner side of the box is provided with a first sliding groove, which is located at the top of the sampling chamber and the sieving chamber. A slot connected to the first sliding groove is provided on one side of the box. A sliding cover plate is installed on the first sliding groove, and the bottom of the cover plate contacts the top of the sieve plate.

[0007] A second sliding groove adapted to the cover plate is provided between the sampling chamber and the screening chamber. The cover plate and the second sliding groove can separate the sampling chamber and the screening chamber, thereby accurately measuring the total amount of feed in the sampling chamber.

[0008] The sampling chamber is designed to hold the feed to be screened. Multiple screening chambers and sieve plates work together to effectively and quickly screen the material in the sampling chamber, allowing feed particles of different sizes to be quickly screened into each screening chamber. At the same time, a cover plate and a first sliding groove are designed to ensure the sealing of the box during screening. The box has a small volume, making it easy to hold and shake for screening, thus improving the convenience of operation.

[0009] A further technical solution is that the box body is made of transparent plastic, and multiple sets of measuring scale lines are set on the box body, which correspond to the sampling chamber and the screening chamber respectively. By setting the box body to be spliced ​​together from transparent plastic plates, it can quickly and accurately measure the feed screened in multiple screening chambers in conjunction with the measuring scale lines, thereby effectively improving the efficiency of screening and measuring feed.

[0010] A further technical solution is that the sieve plate includes a plate frame and a sieve mesh, with the sieve mesh installed on the plate frame. The box body has multiple sets of third sliding grooves corresponding to the plate frame. The plate frame and the third sliding grooves are slidably connected. By setting the plate frame and the third sliding grooves to cooperate, the plate frame and the sieve mesh can be detachably connected to the box body, thereby facilitating the replacement of sieve meshes with different mesh sizes according to usage requirements and improving the practicality of the device.

[0011] A further technical solution is that one side of the cover plate is pointed, and a pull block is installed on the cover plate. The pointed shape of one side of the cover plate facilitates the insertion of the cover plate into the first and second slide grooves, improving the convenience of operation.

[0012] A further technical solution involves installing a fixing block on one side of the box, with a retractable limiting block installed on the fixing block. The limiting block is used to block the slot on the box that connects to the first sliding groove. A spring is installed inside the fixing block, with both ends of the spring connected to the fixing block and the limiting block, respectively. By setting the fixing block, the limiting block, and the spring in coordination, the box can be shaken and screened, and the cover plate in the first sliding groove can be limited, so that the cover plate maintains good sealing of the sampling chamber and the screening chamber, preventing feed from spilling out and affecting the subsequent measurement accuracy.

[0013] This utility model has the following advantages: It features a sampling chamber for holding the feed to be screened, and multiple screening chambers and sieve plates work together to effectively and quickly screen the material within the sampling chamber, allowing feed particles of different sizes to be rapidly screened into each screening chamber. A cover plate and a first sliding groove work together to ensure the box is sealed during screening. The box has a small volume, making it easy to hold and shake for screening, thus improving operational convenience. The box is made of transparent plastic panels, which, in conjunction with the measuring scale, allow for rapid and accurate measurement of the screened feed within the multiple screening chambers, thereby effectively improving the efficiency of feed screening and measurement.
