Abstract
The utility model relates to a long tooth rolls harrow belongs to technical field such as mining, mining excavation, tunnel excavation. The utility model discloses have the function that the protection rake teeth was not broken, and can change the rake teeth alone. The utility model discloses a roller bearing, cylinder and rake teeth, rake teeth setting on the cylinder, the rake teeth includes rake teeth upper portion and rake teeth root, is in the same place through preventing disconnected structural connection with the rake teeth root in rake teeth upper portion, and the rake teeth root can be dismantled the connected mode with the cylinder adoption and link together. The utility model discloses mainly used harrows the material.
Description
Technical field
The utility model relates to long tooth and rolls rake, belongs to the technical fields such as mining, mining excavation, tunnel excavation.
Background technology
Roll rake length and be used in mining industry digging, mining excavation and tunnel excavation field; be arranged on corresponding equipment and carry out work; existing a kind of conventional long tooth rolls rake; in the process of rake material, due to the hard material of some bulks, often can cause the fracture of rake teeth; when rake teeth ruptures to certain quantity; this rolls rake and has just scrapped, and comprises rake cylinder and is all done for, cause very large waste.
Utility model content
The purpose of this utility model is the above-mentioned defect solving prior art existence, proposes a kind of long tooth and rolls rake, and it has protection rake teeth not by the function fractureed, and can change rake teeth separately.
The utility model adopts following technical scheme to realize: a kind of long tooth rolls rake, comprise roller bearing, cylinder and rake teeth, rake teeth is arranged on cylinder, described rake teeth comprises rake teeth top and rake teeth root, rake teeth top and rake teeth root are linked together by break structure, and rake teeth root and cylinder adopt the mode of removably connecting to link together.
Described roller bearing and cylinder are integral type structure.
Described break structure comprises leaf spring and hinge, and rake teeth top is passed through together with stud connection with rake teeth root, and leaf spring one end is fixed on rake teeth top, and the other end is fixed on rake teeth root.
Described break structure comprises torsion spring and hinge, and rake teeth top is passed through together with stud connection with rake teeth root, and torsion spring is arranged on hinge, and torsion spring two ends are connected on rake teeth top and rake teeth root.
The described mode that removably connects is for being threaded or dome connection.
The beneficial effects of the utility model are:
The utility model can effectively prevent rake teeth from fractureing, and can change rake teeth very easily.

In figure: 1 roller bearing 2 cylinder 3 break structure 4 rake teeth top 5 rake teeth root 6 leaf spring 7 dome 8 torsion spring 9 hinge.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further.
As depicted in figs. 1 and 2, described long tooth rolls rake, comprises roller bearing 1, cylinder 2 and rake teeth, and described roller bearing 1 and cylinder 2 are fixed together, and roller bearing 1 and cylinder 2 also can be integral type structure.Rake teeth is arranged on cylinder 2, and described rake teeth comprises rake teeth top 4 and rake teeth root 5, and rake teeth top 4 and rake teeth root 5 are linked together by break structure 3, and rake teeth root 5 and cylinder 2 adopt the mode of removably connecting to link together.
Described break structure 3 comprises leaf spring type and torsion spring type two kinds of embodiments, as shown in Figure 5, leaf spring type break structure 3 comprises leaf spring 6 and hinge 9, rake teeth top 4 and rake teeth root 5 are linked together by hinge 9, leaf spring 6 one end is fixed on rake teeth top 4, and the other end is fixed on rake teeth root 5.The flexibility that this break structure 3 can make rake teeth keep certain, runs into bulk materials or hard material rolling rake, and when exceeding the stressed limit of rake teeth, rake teeth can bend certain angle around hinge 9, makes rake teeth from damage.
As shown in Figure 6 and Figure 7, torsion spring type break structure 3 comprises torsion spring 8 and hinge 9, and rake teeth top 4 and rake teeth root 5 are linked together by hinge 9, and torsion spring 8 is arranged on hinge 9, and torsion spring 8 two ends are connected on rake teeth top 4 and rake teeth root 5.The flexibility that this break structure 3 can make rake teeth keep certain equally, runs into bulk materials or hard material rolling rake, and when exceeding the stressed limit of rake teeth, rake teeth can bend certain angle around hinge 9, makes rake teeth from damage.
As shown in Figure 3, the described mode that removably connects is for being threaded, and now the lower end of rake teeth root 5 is necessary for cylinder, column part is provided with screw thread, is connected, like this with the screwed hole be arranged on cylinder 2, when rake teeth damages, when needing to change, just can by single rake teeth dismounting and change.
Be illustrated in figure 4 dome to connect, dome 7 is arranged on rake teeth root 5 lower end, and with the groove fit be arranged on cylinder 2, this structure is also conveniently change the rake teeth be damaged.
Certainly, foregoing is only preferred embodiment of the present utility model, can not be considered to the scope of embodiments for limiting utility model.The utility model is also not limited in above-mentioned citing, and equalization change and improvement etc. that those skilled in the art make in essential scope of the present utility model, all should belong to the utility model patent covering scope.
