The hammer head is flat cylindrical, the hammer handle is vertically arranged on the hammer head through the hammer head groove, and a tester can knock and crush loess blocks by using the rubber hammer in a nearly vertical direction;
the hammer head is flat cylindrical, is made of rubber, and has a large knocking surface;
the hammer is fixed in the hammer groove through a hammer fixing bolt.
The rubber hammer is flat cylindrical, the hammer handle is vertically arranged on the rubber hammer through the hammer head groove, and a tester can knock and crush loess clods by using the rubber hammer in a nearly vertical direction, so that the tester can exert force when crushing loess;
the hammer head is flat cylindrical, is made of rubber, has a large knocking surface, can improve loess grinding efficiency in a laboratory, and can not damage the integrality of loess particles;
the rubber hammer is fixed in the hammer groove through the hammer fixing bolt, and the hammer is convenient to replace.
Compared with the prior art, the utility model has the beneficial effects that:
the utility model discloses can make the experimenter use with nearly vertical direction, the loess soil block of placing in ground is crushed to the experimenter of being convenient for, can improve the laboratory and grind loess efficiency, and the rubber tup can not destroy loess granule integrality, and the tup is changed conveniently, low in manufacturing cost.
