Description

Aggregate sampling drill

Technical Field

The invention belongs to the technical field of concrete production equipment, and particularly relates to a aggregate sampling drill.

Background

With the tightening of the national environmental protection policy, the mining of the mountain stones, river sands and pebbles is strictly limited. The shortage of natural sand and machine-made sand resources has led to the sub-sufficiency of some material suppliers to gain violence. Poor quality fine aggregate can cause the strength and durability of produced concrete to be reduced and even the concrete is unqualified, and in order to reduce the quality risk of concrete production enterprises, the sampling and detection frequency of the incoming fine aggregate must be increased.

At present, sampling device's drill bit is the spiral feeding mode mostly, through set up the defeated material pole of spiral in getting the feed cylinder, gets to be drawn into the aggregate through rotating the defeated material pole of spiral after locating the drill bit in the aggregate during material, gets material efficiency lower, because the defeated material pole of built-in spiral leads to getting the feed cylinder in effective capacity less.

Disclosure of Invention

Based on the problems mentioned in the background art, the invention provides an aggregate sampling drill, which is used for solving the problems of low material taking efficiency and small effective capacity of the existing aggregate sampling drill.

The technical scheme adopted by the invention is as follows:

On the basis of the technical scheme, the invention also improves the following steps:

further, the inner bottom of the cylinder body is provided with a cone. Aggregate sample along the centrum landing in order to avoid remaining a large amount of aggregate samples can't fall out in the barrel when the blowing.

Furthermore, the material inlet end is provided with a slope surface, and the slope of the slope surface is matched with the slope of the cone body. The aggregate sample can be prevented from remaining at the bottom end of the feed inlet when falling out.

Furthermore, a spiral convex strip is arranged on the cylinder body. The cylinder body can more easily go deep into the aggregate pile when taking materials.

Further, the drill bit is of a hollow structure. The weight of the whole sampling drill is reduced, and the sampling drill is convenient to use.

Further, a first mounting groove, a second mounting groove and a sliding groove are arranged on the cylinder body, a cleaning strip is arranged in the first mounting groove in a sliding manner, a transmission disc is arranged in the second mounting groove in a sliding manner, a first wedge block is arranged at the bottom end of the transmission disc, the first wedge block is provided with a T-shaped block which is arranged in the sliding groove in a sliding way, the top end of the transmission disc is provided with a second wedge block, the second wedge block is provided with a first wedge surface and a second wedge surface, the transmission rod is provided with a third installation groove, the transmission rod is provided with a transmission piece in the third installation groove in a sliding way, the transmission piece comprises a base and a top block which are integrally formed, the top block is provided with a third wedge surface and a fourth wedge surface, the base is provided with a connecting rod, the connecting rod penetrates through the transmission rod, the transmission rod is provided with a limiting ring, the connecting rod is sleeved with a spring, and the spring is located between the transmission rod and the limiting ring. When the driving rod drives the sealing plate to rotate to seal the feeding hole, the second wedge surface and the fourth wedge surface are matched to enable the top block of the driving part to pass through the outer side of the second wedge block, and the driving plate cleaning strip is not pushed downwards and does not move; and when the drive line rotated the shrouding and rotated and open the feed inlet, first scarf and the cooperation of third scarf, pushed the second voussoir downwards through the kicking block, the driving disc promoted through first voussoir that the clearance strip removes and hugs closely the shrouding surface, cleared up the grit that is attached to the shrouding surface through the clearance strip, avoided the grit card to go into to cause surface wear between the inner wall of shrouding and barrel and lead to barrel and shrouding card to die even.

Further, the cleaning strip comprises a base strip and a rubber strip arranged on the base strip, a plurality of installation rods are arranged on the base strip, and the installation rods penetrate through the barrel. First voussoir promotes clearance strip moving as a whole through the base strip, and by the lower rubber strip of hardness and shrouding surface contact again, be favorable to improving the clearance effect, can cushion through the rubber strip simultaneously, first voussoir can't continue to remove and lead to the driving medium to be died and lead to the fact the unable rotation of transfer line by the card after avoiding the rubber strip to contact with the shrouding.

The invention has the beneficial effects that:

through putting into the barrel in the aggregate heap again the drive transfer line rotates and drives the shrouding and remove and open the inner wall that the feed inlet made the aggregate get into the barrel, pull out the barrel from the aggregate heap after closing the feed inlet again and can accomplish the sample, sampling efficiency is higher, convenient to use, and the effective capacity of barrel is great.
