Detailed Description
The present invention will be further explained with reference to the drawings and examples.
As shown in fig. 1 and 2, the utility model discloses a full-automatic particulate matter sampler convenient to move, including support frame 1, be provided with sample thief body 2 on the support frame 1, the rear end of support frame 1 is provided with drive shaft 3 and motor 5, the both ends of drive shaft 3 are provided with gyro wheel 4, motor 5 is connected with drive shaft 3 transmission; the front end of the support frame 1 is provided with at least one vertical threaded hole, a horizontal cross rod 6 is arranged in the threaded hole, a sleeve 7 perpendicular to the cross rod 6 is hinged to the cross rod 6, a positioning screw rod 8 in sliding fit with the sleeve 7 is arranged in the sleeve 7, a support nut 14 is arranged on the positioning screw rod 8 below the sleeve 7, and a handle 9 is arranged at the top of the positioning screw rod 8.
The support frame 1 can be a rectangular frame structure formed by welding angle steel, I-steel, steel pipes and the like and used for supporting other equipment. The sampler body 2 can be an existing impact type air sampler. The motor 5 is in transmission connection with the driving shaft 3 and is used for driving the driving shaft 3 to rotate, and the driving shaft 3 can drive the roller 4 to rotate when rotating, so that the whole sampler is pushed to move. A storage battery can be mounted on the support frame 1 for providing electric energy for the motor 5. The motor 5 and the driving shaft 3 can be connected by a reduction gear set or the like, or can be connected by a belt. The positioning screw rod 8 is used for supporting the support frame 1, specifically, when sampling, the motor 5 does not work, the lower end of the positioning screw rod 8 is in contact with the ground, and the support nut 14 on the positioning screw rod 8 supports the sleeve 7, so that the cross rod 6 is supported, and the whole sampler is kept stable. When the sampler needs to be moved, the handle 9 is pulled upwards, the lower end of the positioning screw rod 8 is separated from the ground, then the motor 5 is started, and the whole device can be pushed to move. The sleeve 7 is hinged to the cross bar 6 so that the positioning screw 8 can rotate relative to the cross bar 6 to facilitate the whole device to be pulled to advance through the positioning screw 8, and meanwhile, the positioning screw 8 can be adjusted to be arranged in a position so that the support nut 14 supports the cross bar 6 to keep the whole sampler stable.
In order to avoid that the positioning screw rod 8 automatically rotates around the cross rod 6 during sampling and ensure the stability of the positioning screw rod 8, the cross rod 6 is a pipe fitting, the cross rod 6 comprises a left rod and a right rod which are coaxial, a space is formed between the left rod and the right rod, a rotating shaft 10 is arranged in the space, one end of the rotating shaft 10 is inserted into the left rod and is in rotating fit with the left rod, the other end of the rotating shaft 10 is inserted into the right rod and is in rotating fit with the right rod, a radial positioning hole is formed in one end of the rotating shaft 10, and a positioning pin 11 which is radially inserted into the positioning hole is arranged on the left rod or the; the sleeve 7 is fixedly arranged on the rotating shaft 10.
