The utility model has following beneficial effect:

1, the utility model adopts the bucket type sampling, can prevent that sampler from stopping up.When bunker gate was closed, because gate control spring tension force is very big, the bunker gate sampling hopper that will clash shook the material that sticks on the sampling hopper fall, thereby realized the self-cleaning of hopper.Greatly reduced the maintaining expense.

2, the utility model drives and has adopted unpowered actuating device of the spring, is adapted at moving under the rugged surroundings, has improved operating condition greatly, has improved the whole service life of sampler.By the tensile force of two gate control springs, realize the closure of bunker gate and the maintenance of gate state, unpowered driving, simple in structure, adapt to the requirement of rugged surroundings, and tensile force is easy to adjust.

3, the sampling hopper can separate with system, can discharging in mobile range freely, and avoid sample contamination and be subjected to the restriction of environment, can clear up machine intimate at any time at assigned address.

In order to obtain better effect, can take following measure:

1, can install the sampling muzzle additional at sampling hopper mouth, the size of sample tap can by the sampling muzzle more bring adjusting, very simple and convenient, can be according to user's needs, free adjustment.

2, drive unit adopts variable-frequency motor, realizes stepless speed regulation.

3, taking environmental conservation into consideration problem prevents that dust from confusingly loosing, and whole device external, promptly block support outside installs dust cover additional.So just need not increase other dust preventions, realize the totally enclosed type dustproof construction.

4, the open and close controlling block can adopt electromechanical stop formula structures such as hard metal piece, and volume is little, simple in structure, reliable for effect.

This bucket type sampler can be used for quantitative sampling, also can be used for timing sampling; Compact overall structure, good dustproof effect is adapted to various hostile environments.By regulating the tension force of tensioning spring, make the inside self-cleaning of the hopper of taking a sample at any time in the sampling process, be not subjected to the influence of raw meal particle size, composition and water cut, lightheartedly carry out online or single-set operation and use.
