Embodiment 1

[0036] Such as figure 1 and figure 2 As shown, the embodiment of the present invention provides an automatic measurement system for grain bulk density of a large-scale grain depot, including a grain bin 1, a walking frame 2, a grain fetching device 3 and a weighing device 4, and the specific settings are as follows:

[0037] The granary 1 is mainly used for arranging grain. The walking frame 2 is arranged in the granary 1 to form vertical and horizontal walking tracks on the top of the granary 1. Specifically, the walking frame 2 includes two longitudinal rowing frames 21 and two horizontal rowing frames 22. The two longitudinal rowing frames 21 It is oppositely arranged on both sides of the granary 1, and forms a longitudinal walking track on the top of the granary 1. Two horizontal racks 22 are arranged in parallel, and are erected between the two longitudinal racks 21, and are placed on the top of the granary 1. A horizontal running track is formed, wherein the two ends ...

Embodiment 2

[0046] The embodiment of the present invention provides a kind of automatic measurement method of bulk density, adopts the automatic measurement system of a kind of large-scale grain depot grain bulk density of embodiment 1, comprises the following steps:

[0047] S1. The main control terminal controls the walking component 312 to drive the container 32 to move to the measuring point according to the preset procedure, and controls the lifting component 313 to drive the container 32 to sample the grain at the measuring point;

[0048] S2. Step S1 is repeated at least five times to control the container 32 to sequentially sample at least five different measuring points;

[0049] S3. After the sampling is completed, control the container 32 to move to the top of the grain tank 41, and control the lifting assembly 313 to drive the container 32 to stake out the grain tank 41;

[0050] S4. After the container 32 is set out, the weight sensor 42 weighs the grain in the grain tank 41 ...

Embodiment 3

[0053] The difference from Embodiment 2 is that a method for automatic measurement of bulk density also includes: arranging a plurality of grain depots, arranging a set of automatic measurement systems for bulk density in each grain depot, and setting up a total server, and connecting the total server with each set of bulk density The main control terminal of the automatic measurement system is connected by communication to form a local area communication network. The main control terminal in each grain depot uploads the measured weighing value to the general server, and then the general server uploads it according to the information uploaded by each grain depot. The weighing value is used for mean value calculation and data analysis, so as to facilitate centralized monitoring of the weighing conditions of multiple grain depots.

Abstract

The embodiment of the invention discloses a large-scale grain depot grain volume weight automatic measurement system and measurement method, the system comprises a grain bin, a walking frame, a graintaking device and a weighing device, the walking frame is arranged in the grain bin so as to form longitudinal and transverse walking tracks at the top of the grain bin, and the grain taking device comprises a movement mechanism and a container; the moving mechanism drives the container to sample grains in sequence at at least five measuring point positions along the walking track, the weighing device comprises a grain tank and a weight sensor, the moving mechanism drives the container to loft into the grain tank, the weight sensor weighs the grains in the grain tank for 3-5 times, and a meanvalue is obtained and the measured mean value is returned to the main control terminal. Manual weight measurement is not needed, the measurement process is more convenient, personnel injury risks in the measurement process are reduced, data arrangement is clearer and simpler by combining with the Internet technology, the related range is wider and more comprehensive, and subsequent centralized processing and further utilization are facilitated.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of grain depot inspection, and in particular to a large-scale grain depot automatic grain bulk density measurement system and measurement method. Background technique [0002] Through the investigation of local grain depots, it is found that the current grain depots usually use the weighing method of 1 cubic meter wooden box to measure the bulk density of grain. The height of a large-scale grain depot is generally 6-12 meters. Each measurement needs to lift the wooden box and heavy electronic scale from the peripheral stairs to the top of the granary, and carry out manual weighing and measurement of grain. Take the measurement of the grain bulk density of a 50m×24m×6m grain depot as an example. Usually, two workers each hold a shovel and a sack, take samples at points 5-7cm below the top of the grain depot, and then pour them back into the wooden box and work back and forth. 6-7 ti...
