Shellfish sorting knocking device
Technical field
Thereby the utility model relates to a kind of shellfish sorting unit that carries out sorting by the discriminating of knocking shellfish housing sounding, especially can be used for striking the automation sorting machine of the dead shellfish of sound identification clam class, broken shellfish, mud shellfish, particularly relate to a kind of shellfish sorting knocking device.
Background technology
At present, known bar such as the drumstick shape of knocking, some is terminal or have ball bumps, and the whole body of rod is equal to a kind of material by metal, bamboo and wood or plastics and makes.This type of knocks bar when knocking shell after tested, and bar and shell all can send the significant sound simultaneously separately.This gives by striking sound and detects bad shellfish and cause difficulty, causes misjudgment easily.In addition, when being used for machinery and knocking, the percussion power of this type of rigidity straight-bar can be subjected to the appreciable impact of the size of shell, causes the bigger shellfish body of specification to be subjected to too heavy strike easily and causes cracked, the little shellfish body then may be because of touching or dynamics too gently can't obtain the suitable sound.
The utility model content
The purpose of this utility model is to provide a kind of can reduce the noise of the body of rod, adaptable shellfish sorting knocking device greatly.
For achieving the above object, technical solution of the present utility model is:
Utility model is a kind of shellfish sorting knocking device, it mainly by base, support, knock bar, drive rod, electromagnet, extension spring and form; The lower end of described support is fixed on the base; The rear portion of described drive rod is hinged on cantilever tip, knocks bar and is installed in the drive rod front end, and the tail end of drive rod is connected with the upper end of extension spring, and the lower end of extension spring is connected on the base, and electromagnet is installed on the base and is positioned at the below at drive rod middle part; The described bar that knocks is made up of striking head and elastic component, and the inner of striking head connects an end of elastic component, and the other end of elastic component connects the front end of drive rod.
Described elastic component is a spring, and striking head is a spheroid; The two ends of described spring are connected on the striking head and knock the front end of bar.
Described elastic component is a rubber tube, and described striking head is a rod member, and this rod member is plugged on the rubber tube one end endoporus, and rubber tube other end inner hole sleeve is connected on the drive rod front end.
After adopting such scheme, because the utility model drive rod is connected with striking head by elastic component, this knocks the noise that can reduce the body of rod when bar is applied to shellfish and strikes sound greatly, this knocks bar and can significantly improve adaptability to the inhomogeneous situation of shellfish body size when being applied to mechanization and knocking, and striking head can be resetted fast, satisfy the needs that high speed shellfish separator high-frequency is knocked.The utility model has overcome traditional bar that knocks and has been applied to the mixing sound to occur when shellfish strikes the sound monitoring, and the deficiency of hindering shellfish when Mechanical Driven easily, satisfies the needs that high speed shellfish separator high-frequency is knocked.
Below in conjunction with the drawings and specific embodiments the utility model is further described.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is first enforcement illustration of the utility model striking head;
Fig. 3 is that second of the utility model striking head implements illustration.
The specific embodiment
As shown in Figure 1, the utility model is a kind of shellfish sorting knocking device, it mainly by base 1, support 2, knock bar 3, drive rod 4, electromagnet 5, extension spring 6 and form.
The lower end of described support 2 is fixed on the base 1; The rear portion of described drive rod 4 is hinged on support 2 tops, knock bar 3 and be installed in drive rod 4 front ends, the tail end of drive rod 4 is connected with the upper end of extension spring 6, the lower end of extension spring 6 is connected on the base 1, electromagnet 5 is installed on the base 1 and is positioned at the below at drive rod 4 middle parts, for can with electromagnet 5 mutual adhesives, be provided with iron plate at drive rod 4 and electromagnet 5 opposite positions, also drive rod 4 can be designed to metalwork.
With reference to shown in Figure 1, the described bar 3 that knocks is made up of striking head 31 and elastic component 32 as Fig. 2.Described elastic component 32 is a spring 32, and striking head 31 is a metal ball body 31.The two ends of described spring 32 are connected on the striking head 31 and the front end of drive rod 4.
With reference to shown in Figure 1, described elastic component 32 ' is a rubber tube 32 ' as Fig. 3, and described striking head 31 ' is a rod member 31 ', and this rod member 31 ' is plugged on rubber tube 32 ' the one end endoporus, and rubber tube 32 ' other end inner hole sleeve is connected on drive rod 4 ' front end.
Emphasis of the present utility model just is: striking head is connected with drive rod by elastic component.
The above, it only is the utility model preferred embodiment, the version of striking head and elastic component can have multiple, so can not limit the scope that the utility model is implemented with this, the i.e. equivalence of doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model patent contains.
