TECHNICAL FIELD
[0001] The utility model relates to grain detection equipment technical field, concretely relates to full -automatic grain comminution mixes and takes sample all -in -one. BACKGROUND
[0002] At present, the sample pre -treatment (comminution, mixes and takes sample) in grain detection still highly depends on manual operation, and the process is complicated and has many technical defects, which seriously affects the detection efficiency and data accuracy, and the typical process is as follows:
[0003] 1. Comminution link
[0004] Operation steps: manually take a certain amount of wheat or corn and other grain samples (about 200~500g), start the comminution machine, slowly manually feed (need to continuously add a small amount, avoid adding too much at one time), after comminution is completed, manually collect the powder and clean the comminution cavity residues.
[0005] The existing comminution link has the following main shortcomings:
[0006] 1) easy to block: if the feeding speed is too fast or the sample moisture is high (such as corn >14%), the motor load increases sharply, which leads to blocking and even burning, and frequent shutdown is needed for cleaning.
[0007] 2) low efficiency: each batch of comminution needs manual monitoring, and continuous operation cannot be realized, and the single sample processing time is as long as 5~10 minutes, and if the sample quantity is large, the time is multiplied.
[0008] 3) residual pollution: the comminution cavity structure is complex, and the residual powder is difficult to completely remove, and the cross contamination risk is high.
[0009] 2. Mixing link
[0010] Operation steps: pour the comminuted powder into a mixing device (such as a V-shaped mixer or a three-dimensional motion mixing instrument), set the mixing time (usually 3~5 minutes), start the device, and manually pour out the powder after mixing, and prepare for sampling.
[0011] The existing mixing link has the following main shortcomings:
[0012] 1) uneven mixing: the traditional mixing device has serious stratification for samples with large density difference (such as mixing of wheat flour and corn flour), and the uniformity is poor, which affects the representativeness of sampling and detection.
[0013] 2) powder adhesion: the inner wall of the mixing container is easy to adhere to fine powder, which causes the actual sampling quantity to deviate from the expected value.
[0014] 3) more manual intervention: multiple container transfers are needed, which increases the operation error and pollution risk.
[0015] 3. Sampling section
[0016] Operation steps: use a spoon or sample divider to randomly dig a small amount of fixed weight sample from the mixed powder, manually weigh, adjust repeatedly to the target weight, and then send the sample to the test equipment for detection.
[0017] The existing sampling section has the following main shortcomings:
[0018] 1) Large sampling deviation: manual random sampling is easily affected by operation habits, especially when the particle size is uneven (such as corn particles that are not completely crushed), resulting in fluctuation of the test results.
[0019] 2) Low weighing efficiency: multiple weighing and calibration are required, which is time-consuming, labor-intensive and labor-intensive.
[0020] 3) Insufficient accuracy: conventional electronic scales are affected by environmental vibration or temperature and humidity, and cannot meet the high-precision detection requirements.
[0021] 4. Cleaning and maintenance
[0022] Complicated operation: the crusher and mixer need to be disassembled and cleaned, and the dead corners are difficult to completely clean, which takes a long time to clean, frequent disassembly accelerates the aging of mechanical parts, and the equipment is severely worn, resulting in high maintenance cost.
[0023] In summary, the existing equipment has low automation degree, relies on manual operation throughout, has low efficiency and poor repeatability, and has insufficient data reliability: uneven mixing and sampling deviation reduce the reliability of the test results, the equipment has poor stability: frequent problems such as stall, residue and wear affect continuous operation, the labor cost is high, the sampling process is complicated and the accuracy is difficult to guarantee, and large-scale detection requirements cannot be met. These problems need to be solved. Practical new type content
