Abstract
The invention discloses a sampling method of wood and bamboo chips, which comprises the following steps: step 1: acquiring the cargo volume of wood or bamboo chips loaded by a truck; step 2: the sampling control system generates the total unloading time of the truck, the total sampling times of the sampling hoppers and the time interval of opening and sampling of the sampling hoppers of two adjacent times according to the cargo volume; and step 3: after the truck runs to be aligned with the unloading platform, unloading is started; and 4, step 4: during the unloading operation of the truck, when a sampling hopper of the sampler is opened every time, the wood or bamboo chips on the truck are poured into the sampling hopper, and the sampling is stopped after the total sampling times are reached; and 5: the material that the sampling fill was collected gets into the collecting vessel through the conveyer belt of fighting the below, mixes the material of collecting vessel, then sends to next process and carries out the inspection of relevant physicochemical index. By adopting the technical scheme, the automatic random sampling is realized, the sampling is prevented from being interfered by human factors, and the sampling result is more real and accurate.
Description
Technical Field
The invention relates to the field of sampling, in particular to a wood and bamboo chip sampling method.
Background
The fair problem of wood (bamboo) sheet sampling is always a difficult problem which puzzles raw material purchasing of domestic paper making enterprises, and the conventional manual sampling method has the disadvantages that partial sampling personnel, unloading workers and suppliers are involved with each other due to poor randomness and a plurality of interference factors of manual sampling, so that private profit is obtained, and the benefits of companies are damaged as a result.
Disclosure of Invention
In order to overcome the defects in the prior art, the invention aims to provide a wood and bamboo chip sampling method for reducing human factor interference.
In order to achieve the purpose, the invention adopts the following technical scheme:
a sampling method of wood and bamboo chips comprises the following steps:
step 1: acquiring the cargo volume of wood or bamboo chips loaded by a truck;
step 2: the sampling control system generates the total unloading time of the truck, the total sampling times of the sampling hoppers and the time interval of opening and sampling of the sampling hoppers of two adjacent times according to the cargo volume;
and step 3: after the truck runs to be aligned with the unloading platform, unloading is started;
and 4, step 4: during the unloading operation of the truck, when a sampling hopper of the sampler is opened every time, the wood or bamboo chips on the truck are poured into the sampling hopper, and the sampling is stopped after the total sampling times are reached;
and 5: the material that the sampling fill was collected gets into the collecting vessel through the conveyer belt of fighting the below, mixes the material of collecting vessel, then sends to next process and carries out the inspection of relevant physicochemical index.
Further, the specific method of step 1: weighing the truck, generating a sequence number on the wagon computer bill, queuing according to the weighing sequence to enter a designated unloading point, and measuring the cargo volume of the truck by a worker to obtain the cargo volume of the whole truck.
Further, the specific method of step 3 is as follows: after the truck runs to be aligned with the unloading platform, the sliding vehicle enters the carriage of the truck for unloading operation.
By adopting the technical scheme, the automatic random sampling is realized, the sampling is prevented from being interfered by human factors, and the sampling result is more real and accurate.
Drawings
The invention is described in further detail below with reference to the accompanying drawings and the detailed description;
FIG. 1 is a schematic illustration of the present invention connected together.
Detailed Description
As shown in figure 1, the invention relates to a method for sampling wood and bamboo chips, which comprises the following steps:
step 1: weighing a truck, generating a sequence number on a wagon computer bill, queuing to enter a designated unloading point according to the weighing sequence, and measuring the cargo volume of the truck by a worker to obtain the cargo volume of the whole truck;
step 2: the sampling control system generates the total unloading time of the truck, the total sampling times of the sampling hoppers 2 and the time interval of opening and sampling of the sampling hoppers 2 in two adjacent times according to the cargo volume;
and step 3: after the truck runs to be aligned with the unloading platform 1 and the truck runs to be aligned with the unloading platform 1, the sliding vehicle enters a carriage of the truck for unloading operation;
and 4, step 4: in the unloading operation process of the truck, when the sampling hopper 2 of the sampler is opened every time, the wood or bamboo chips on the truck are poured into the sampling hopper 2, and the sampling is stopped after the total sampling times are reached;
and 5: the material that the sampling funnel 2 was collected gets into collecting vessel 4 through conveyer belt 3 of fighting the below, mixes collecting vessel 4's material, then sends to next process and carries out the inspection of relevant physicochemical index, finally reachs the water content of wood (bamboo) piece, the content of impurity.
While the invention has been described in connection with the above embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, which are illustrative and not restrictive, and that those skilled in the art will understand that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention, and they should be construed as being included in the following claims and description.
