Background
According to the condition analysis of the industry, the crushing sand making machine for crushing the massive stones into the fine stones has good development trend at present, and becomes a traditional and brand-new business creation field at home and abroad. China has abundant mountain stone resources, provides sufficient raw materials for the production of artificial sand, and along with the integration and adjustment of the mine industry, the crushing sand making machine exerts excellent advantages under the fumigation of the environment, but some problems generated in the production, such as that the crushing sand making equipment shows backward and seriously wastes resources, bring great obstacles to the progress of the sand and stone industry. Therefore, the development of the industry tends to be high-end and high-efficiency sand making machine. At present, real estate in China is developed quickly, and projects such as western large development, middle rising and the like are developed comprehensively, so that good development opportunities are provided for the crushing sand making machine industry in future, the crushing sand making machine has very large market demand regardless of domestic and foreign countries, and the prospect is bright.
The existing crushing sand making machine is provided with a rotating body, the rotating body is provided with a rotating shaft, a hammer body and a hammer head, the hammer body is arranged on the rotating shaft, and the hammer head is arranged on the hammer body through a fastening screw.
When the crushing sand making machine works, part of sand entering the crushing sand making machine from the feeding hole falls on the upper surface of the rotating body freely, so that the upper surface of the rotating body is easy to deform and damage. Meanwhile, the sand falling from the free falling body is crushed into fine sand by the hammer head rotating at a high speed, so that the hammer head is easy to wear, the hammer head is required to be replaced when the crushing sand making machine works for a certain time, the service life of the hammer head is short, the loss is large, and the running cost of the crushing sand making machine is very high.
Disclosure of Invention
The utility model aims at providing a portable hammer head structure of broken system sand machine to the life of solving broken system sand machine tup is short, the loss volume is big, makes the very high problem of running cost of broken system sand machine.
The technical scheme of the utility model is that: a movable hammer head structure of a crushing sand making machine is provided with a rotating body, wherein the rotating body comprises a hammer body and a hammer head, the hammer body is arranged on a rotating shaft of the crushing sand making machine, and one or more grooves are formed in the hammer body; the hammer head is provided with an edge matched with the groove on the hammer body and a fastening screw mounting groove, and the edge and the fastening screw mounting groove are mounted on the hammer body through a fastening screw.
The utility model discloses further technical scheme is: three grooves are arranged on the hammer body.
The utility model discloses further technical scheme is: when the hammer is installed for the first time, the edge on the hammer head is correspondingly arranged in the first groove closest to the rotating shaft; when the hammer head reaches one third of abrasion loss, the hammer head is installed again, and the ridge on the hammer head corresponds to the second groove; when the hammer reaches two thirds of abrasion loss, when reinstalling the hammer, correspond the arris on the hammer in third groove.
The utility model discloses still further technical scheme is: an end guard plate is arranged on the upper surface of the rotating body.
The utility model discloses still further technical scheme is: the end protection plate is provided with a square cone hole and is arranged on the rotator through a square cone bolt.
Due to the design, the hammer head can be used for multiple times, the service life of the hammer head is greatly prolonged, and the defects of short service life and large loss of the hammer head in the prior art are overcome, so that the operating cost of the crushing sand making machine is very high; meanwhile, because the end protection plate with the square cone hole is arranged on the rotating body, the service life of the rotating body is greatly prolonged, and the service life of the crushing sand making machine is effectively prolonged.
The invention is further described below with reference to the figures and examples.

Detailed Description
The first embodiment is as follows:
as shown in fig. 1-8, a movable hammer head structure of a crushing and sand-making machine is provided with a rotating body 1, wherein the rotating body 1 comprises a hammer body 2 and a hammer head 3, the hammer body 2 is arranged on a rotating shaft of the crushing and sand-making machine, and a first groove 21, a second groove 22 and a third groove 23 are formed in the hammer body; the hammer head 3 has an edge 31 that mates with a groove on the hammer body 2 and a fastening screw mounting slot 32 that is mounted to the hammer body 2 with a fastening screw 4. An end protection plate 5 with a square cone hole is arranged on the rotary body 1, and the end protection plate with the square cone hole is arranged on the rotary body 1 through a square cone bolt 6.
When the utility model is installed for the first time, the edge 31 on the hammer head 3 is corresponding to the first groove 21 closest to the rotating shaft; when the hammer head 3 is reinstalled after reaching one third of the abrasion loss, the ridge 31 on the hammer head 3 is corresponding to the second groove 22; when the hammer 3 is reinstalled after reaching two thirds of the abrasion loss, the edge 31 on the hammer 3 is corresponding to the third groove 23.
