Abstract
The utility model discloses a riverway quarrying excavation head. The riverway quarrying excavation head comprises an excavation head body and a connecting part arranged at the upper end of the excavation head body. An inner cavity is formed in the excavation head body. Antifriction frames are arranged on the two sides of the top of the inner cavity, one or more reinforcing ribs are transversely arranged at the bottom of the inner cavity, the two sides of each reinforcing rib are connected with the two side faces of the inner cavity, one or more fixing shafts are arranged on the rear surfaces of the reinforcing ribs, the two side faces of the inner cavity are respectively provided with a fixing rod, vent openings are formed in the two sides of each fixing rod, one or more bucket teeth are installed on the front end face of the bottom of the excavation head body, and wearproof protection teeth are arranged between every two adjacent bucket teeth. The riverway quarrying excavation head is simple in structure and convenient to manufacture; in the use process, filtering inside the excavation head is complete, excavation efficiency is afflictively improved, and by the adoption a reasonable connecting mode, the service life of the excavation head is effectively prolonged.
Description
Technical field
The utility model relates to a kind of river course quarrying mining head.
Background technology
The river course quarrying of prior art is carried out operation by common mining head, because the mining head of prior art adopts enclosed design, contains various materials in mining head inner chamber, cannot carry out the very first time and filter, and need to carry out secondary sorting, very trouble.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of simple in structure, reasonable in design, and digging efficiency is high, and the river course of long service life quarrying mining head.
For addressing the above problem, the utility model adopts following technical scheme: a kind of river course quarrying mining head, comprise mining head body, and be arranged on the coupling part of mining head body upper end, in mining head body, be provided with inner chamber, inner cavity top both sides are provided with antifriction frame, the bottom transverse of inner chamber is provided with an above reinforcing rib, and the both sides of reinforcing rib are connected with inner chamber two sides, the rear surface of reinforcing rib is provided with an above fixed axis, inner chamber two sides are equipped with a fixed bar, fixed bar both sides are provided with leak, the bottom front face of mining head body is provided with and is provided with more than one bucket tooth, between two adjacent bucket tooths, be provided with the wear-resisting tooth that protects.
As preferred technical scheme, the inner surface of fixed axis and the bottom surface of reinforcing rib adopt and are welded to connect.
The beneficial effects of the utility model are: the utility model is simple in structure, easy to make, and in use, its self-filtering is thorough, effectively improves digging efficiency, by rational connected mode, effectively increase the application life of mining head.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model river course quarrying mining head.
Detailed description of the invention
Refer to shown in Fig. 1, a kind of river course quarrying mining head, comprise mining head body 1, and be arranged on the coupling part 2 of mining head body 1 upper end, in mining head body 1, be provided with inner chamber 3, inner chamber 3 both sides, top are provided with antifriction frame 4, the bottom transverse of inner chamber 3 is provided with an above reinforcing rib 9, and the both sides of reinforcing rib 9 are connected with inner chamber 3 two sides, the rear surface of reinforcing rib 9 is provided with an above fixed axis 5, inner chamber 3 two sides are equipped with a fixed bar 10, fixed bar 10 both sides are provided with leak 6, the bottom front face of mining head body 1 is provided with and is provided with more than one bucket tooth 8, between two adjacent bucket tooths 8, be provided with the wear-resisting tooth 7 that protects.
As preferred technical scheme, the bottom surface of the inner surface of fixed axis 5 and reinforcing rib 9 adopts and is welded to connect.
The utility model is by arranging being connected of fixed axis 5 and reinforcing rib 9 in inner chamber 3 bottom surfaces; the impurity such as sand and water can by between space spill; can make inner stream flow increase by leak 6; make the more thorough of self-filtering; and the pressure of scraper bowl inside while reducing work; at inner chamber 3 tops and mining head body 1 bottom, antifriction frame 4, bucket tooth 8 and the wear-resisting tooth 7 that protects are set respectively; not only be convenient to excavate; and can protect significant points to produce wearing and tearing too early and cause damaging, effectively increase its application life.
The beneficial effects of the utility model are: the utility model is simple in structure, easy to make, and in use, its self-filtering is thorough, effectively improves digging efficiency, by rational connected mode, effectively increase the application life of mining head.
The above, be only detailed description of the invention of the present utility model, but protection domain of the present utility model is not limited to this, and any variation of expecting without creative work or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims were limited.
