Abstract
The utility model discloses an improved combined square hammer for a sand making machine, which belongs to the technical field of crushing machinery. The improved combined square hammer is composed of a square hammer seat 1, a bolt 2 and a square hammer head 4, wherein a transverse groove 3 is arranged in the middle of the front surface of the square hammer head 4; a transverse raised line 6 is arranged in the middle of the back surface of the square hammer head 4, and longitudinal side ribs 5 are respectively arranged on the two sides of the square hammer head; and the back surface of the square hammer head 4 is installed by being clung to the front surface of the square hammer seat 1 and is fixed by the bolt 2. The improved combined square hammer has the characteristics that the machining cost and the operation cost are reduced, the crushing efficiency is also improved, and the like. The improved combined square hammer is used in cooperation with a main shaft of the sand making machine and is suitable for crushing limestone, gravel and ore with great hardness.
Description
Technical field
The utility model relates to the crushing mechanism technical field, particularly a kind ofly makes the modified combination plane set-hammer that the sand machine uses.
Background technology
In the prior art, the combination plane set-hammer that system sand machine is used is to be made up of plane set-hammer seat and plane set-hammer head, and both are by bolt; At the back side of plane set-hammer head, have "+" font convex tendon, also have "+" font groove in the front of plane set-hammer seat, convex tendon and groove match, and realize its horizontal and vertical location.Though its location of this kind design is easier, reliable, the processing capacity of its groove is relatively large and required precision is higher; Simultaneously, the combination plane set-hammer revolves at whole rotor block and is difficult to form no gap in turning around and works, thereby its crushing efficiency is lower; And the two sides easy abrasion of plane set-hammer seat causes operating cost to increase.
Summary of the invention
To the deficiency that prior art exists, the utility model technical problem to be solved provides and a kind ofly can cut down finished cost, also can reduce operating cost and can improve the combination plane set-hammer of crushing efficiency.
The technical scheme that the utility model is taked is to design a kind of modified combination plane set-hammer that the sand machine is used of making: be to be made up of plane set-hammer seat 1 and plane set-hammer head 4; The positive middle part of plane set-hammer seat 1 has transverse concave groove 3; The middle part, the back side of plane set-hammer head 4 has horizontal raised line 6; The front installation of plane set-hammer seat 1 is close at the back side of plane set-hammer head 4, and is fixing by bolt 2; Both sides at plane set-hammer head 4 also have vertical limit muscle 5 respectively.
The modified combination plane set-hammer that the system sand machine of the utility model is used; Abandoned the structure that traditional "+" font convex tendon and groove match, the vertical convex tendon that the plane set-hammer head is middle changes vertical limit muscle of dual-side, the processing that both can save the vertical groove of plane set-hammer seat into; Can let vertical limit muscle of its dual-side encase the two sides of plane set-hammer seat again; The plane set-hammer seat that the plane set-hammer head protection cast steel that lets high-chromium alloy make is made is avoided wearing and tearing, thereby, reduced the operating cost of equipment; In addition, vertical limit muscle of plane set-hammer head dual-side, its lateral dimension has exceeded the two sides of plane set-hammer seat, thereby, make the combination plane set-hammer revolve and be formed naturally the work of no gap in turning around at whole rotor block, therefore, improved the crushing efficiency of complete machine.
Description of drawings
Fig. 1 is that the master of the utility model looks sketch map;
Fig. 2 is that the master of the plane set-hammer head of the utility model looks sketch map;
Fig. 3 is the left cross-sectional schematic of the plane set-hammer head of the utility model.
Among the figure: the 1st, plane set-hammer seat, the 2nd, bolt, the 3rd, transverse concave groove, the 4th, plane set-hammer head, the 5th, vertical limit muscle, the 6th, horizontal raised line, the 7th, axis hole, the 8th, dormant bolt hole.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is further described.Following explanation is to adopt the mode of giving an example, but the protection domain of the utility model should not be limited to this.
Present embodiment is to be made up of plane set-hammer seat 1, bolt 2 and plane set-hammer head 4, and plane set-hammer seat 1 is the rotation symmetry, and the centre has axis hole 7; The positive middle part of one of which end has transverse concave groove 3, and upper and lower position has screw; At the back side of plane set-hammer head 4, the center has horizontal raised line 6, and its both sides also have vertical limit muscle 5 respectively; In the front of plane set-hammer head 4, upper and lower position has dormant bolt hole 8; The front installation of plane set-hammer seat 1 is close at the back side of plane set-hammer head 4, and is fixing by bolt 2; The horizontal raised line 6 at plane set-hammer head 4 back sides inserts in the transverse concave groove 3 in plane set-hammer seat 1 front, realizes vertically location; Located lateral had both been realized in the two sides that vertical limit muscle 5 at plane set-hammer head 4 back sides is clamped plane set-hammer seat 1, can protect the two sides of plane set-hammer seat 1 to avoid wearing and tearing again; Simultaneously, vertical limit muscle of plane set-hammer head 4 exceeds the two sides of plane set-hammer seat 1, is convenient to make up plane set-hammer and revolves at whole rotor block and form no gap in turning around and work.
Before the use, the modified combination plane set-hammer with the system sand machine of the utility model is used is installed on supporting use on the main shaft of making the sand machine.During use, material directly receives impacting of plane set-hammer head 4 after getting into, and by counterpunch board counterattack carrying out second-time breakage.Because vertical limit muscle of plane set-hammer head 4 has exceeded the two sides of plane set-hammer seat 1, be formed naturally no gap in turning around and worked so the combination plane set-hammer revolves at whole rotor block, thereby; The crushing efficiency of its complete machine is higher; And, also protected the two sides of plane set-hammer seat 1, make it avoid wearing and tearing; Thereby, reduced the operating cost of equipment.
The modified combination plane set-hammer that the system sand machine of the utility model is used, device supporting use on the main shaft of system sand machine is applicable to the ore that crushed stone lime stone, gravel and hardness are bigger.
Claims (1)
1. make the modified combination plane set-hammer that the sand machine is used for one kind; Be to constitute by plane set-hammer seat (1) and plane set-hammer head (4); The positive middle part of plane set-hammer seat (1) has transverse concave groove (3); The middle part, the back side of plane set-hammer head (4) has horizontal raised line (6), and the front installation of plane set-hammer seat (1) is close at the back side of plane set-hammer head (4), and is fixing by bolt (2); It is characterized in that: the both sides at plane set-hammer head (4) also have vertical limit muscle (5) respectively.
