Embodiment

The utility model is further illustrated with reference to the accompanying drawings and examples.

As Figure 1-3, a kind of concrete sprayer feed arrangement, including housing, the upper end of housing are feeder 1, shell The lower end of body is discharging portion 2, and the inside of the feeder 1 is provided with screen pack 13, and screen pack 13 is provided with the second spheroid 19, in housing Provided with rotating shaft 4, rotating shaft 4 passes through screen pack 13, is additionally provided with connecting rod 12 in housing, the one end of connecting rod 12 is fixedly connected with rotating shaft 4, connecting rod 12 other ends insert the second spheroid 19 and are rotatablely connected with it.

In use, feeder 1 is used for the charging of the concrete raw materials such as sandstone, cement, discharging portion 2 is used to convey material To the inside of concrete sprayer, screen pack 13 is mainly used in the filtering of material, ensures that the material granule of suitable size enters Inside spraying machine, the second spheroid 19 contacts with screen pack 13, can pulverize the blocking material of larger material or solidification, carry Rise material filter efficiency and screen pack 13 can be dredged, prevent from blocking, guarantee feeding structure and whole spraying machine it is smooth It is logical.Rotating shaft 4 and connecting rod 12, rotating shaft 4 and connecting rod 12 are provided with housing primarily to driving the second spheroid 19 to rotate, second Spheroid 19 could be arranged to one or more.The upper end of rotating shaft 4 is connected with second bearing 10, and second bearing 10 is arranged on first On pole 9, the first pole 9 is connected on support frame 29；The lower end of rotating shaft 4 is connected with clutch shaft bearing 3, and clutch shaft bearing 3 is arranged on On containment vessel 6, containment vessel 6 is connected on support frame 29, and by such connected mode, overall structure has been secured to support frame On 29, support frame 29 is fixed with spraying machine main body again.Rotating shaft 4 passes through from screen pack 13, in order that total is laid out more adduction Reason, also allows material equably to be filtered on screen pack 13, rotating shaft 4 passes through from the center of screen pack 13.In order to drive the second ball Body 19 is rotated, and the one end of connecting rod 12 is fixedly connected with rotating shaft 4, and the other end of connecting rod 12 inserts the second spheroid 19 and realizes that rotation connects Connect, if more connecting rods 12, then connecting rod 12 is located at same level, with the rotation of rotating shaft 4, can drivening rod 12 rotate, Because the spheroid 19 of connecting rod 12 and second is rotation connection relation, therefore connecting rod 12 drives the second spheroid 19 to rotate together, so as to To be stirred to material, accelerate the rate of filtration, while the second spheroid 19 with connecting rod 12 do annulus track movement while, The rotation for rotating shaft with connecting rod 12 can occur, so as to be rolled to the material granule for the caking that makes moist, bulk can be ground Broken, guarantee is smoothly fallen down from screen pack 13.

Second spheroid 19 can be connected with connecting rod 12 using a variety of connected modes, such as be connected using bearing, it is preferable that this dress Put using blind hole 31 is provided with the inside of the second spheroid 19, be provided with the first spheroid 18 in the one end of connecting rod 12, the first spheroid 18 is located at The inside of the blind hole 31, and limited block 24 is provided with the entrance of blind hole 31, limited block mainly prevents the first spheroid 18 from blind hole Depart from 31.

In order to increase the frictional force of the first spheroid 18 and blind hole 31, ensure that the second spheroid 19 can be with smooth rotation, first The surface of spheroid 18 is provided with some the second fins 23, and the inwall of blind hole 31 is provided with some the first fins 22.At work, Second fin 23 contacts with each other with the first fin 22, ensure that the second spheroid 19 also can rotation when rotating around the axis.

Because the spheroid 19 of connecting rod 12 and second is connected by the first spheroid 18 and blind hole 31, the spheroid 19 of connecting rod 12 and second Between certainly exist gap, in order to prevent material from entering inside blind hole 31, be provided with annular groove 25 on connecting rod 12, annular is recessed Groove 25 is located inside blind hole 31, and shutter 26 is additionally provided with connecting rod 12, and shutter 26 is connected with spring 27, the other end of spring 27 It is connected with annular groove 25, annular groove 25 is mainly used in the spacing of spring 27, the contact outside of shutter 26 and limited block 24.

Be additionally provided with several projections 20 on the surface of second spheroid 19, projection 20 can with the second spheroid 19 as one, But so cost is higher, it is preferable that in the present apparatus, projection 20 is separately formed, then is fixed on the second ball by fixed screw 21 On body 19.With the rotation of the second spheroid 19, hemisphere 20 can produce interference with screen pack 13, and hemisphere 20 can be to the mistake of blocking Filter screen 13 is dredged, and is prevented screen pack 13 from blocking, is further lifted filter efficiency.

In order to preferably coordinate with the second spheroid 19, screen pack 13 be provided with annular recess 14, its recessed direction to Under, recess 14 can accommodate the second spheroid 19.Such setting increases the contact area of the second spheroid 19 and screen pack 13, Filter efficiency is also improved, while can also limit the movement locus of the second spheroid 19.

When material feedings such as sandstone, cement, can be sent into by artificial or forklift inside feeder 1, but be directly sent to Screen pack 13 can make material collect in a pile, and filter efficiency is low and the operating pressure of the second spheroid and screen pack is larger, it is preferable that Rotating shaft 4 is provided with a fixed cone 11, and fixed cone 11 is located at the top of screen pack 13, the small position of the diameter of fixed cone 11 upward, So as to which material is evenly directed to the recess 14 of screen pack 13, make filter effect more preferably.At the same time, connecting rod 12 Just be connected on fixed cone 11, with the rotation of rotating shaft 4, fixed cone 11 also can drivening rod 12 rotate, so as to drive whole machine Structure operates.

When bearing too many raw material on screen pack, center section influences machine because no support bar is easy to dented The running of structure, in order to solve this problem, it is additionally provided between the screen pack 13 and the junction of rotating shaft 4 and the inwall of housing Several second poles 17, allow the basic keep level of whole screen pack, be unlikely to cause to collapse because raw material are overweight.

In order to further lift filter effect, any one second pole 17 is provided with jacking block 15, the rotating shaft 4 wherein On be also arranged with rotating wheel 16, the side of rotating wheel 16 is provided with lug boss 8, and lug boss 8 is located at same level with jacking block 15.Should Under structure, the second pole 17 can be supported to the inner side of screen pack 13, and when the spindle is rotated, lug boss 8 can be with jacking block 15 Intermittent interference, so as to drive the second pole 17, screen pack 13 and feeder 1 to vibrate therewith, the vibrating effect can facilitate Sand material more smoothly passes over screen pack 13, increase discharging effect, also can further prevent from blocking.

In order to prevent that caused dust is excessive in the course of work, water pipe 33, water pipe 33 are additionally provided with inside described feeder 1 Hole for water spraying 34 is provided with, sprays tiny current, the dust in fill process can be adsorbed, prevent air pollution.

In description of the present utility model, it is to be understood that term " longitudinal direction ", " transverse direction ", " on ", " under ", " preceding ", The orientation or position relationship of the instruction such as " rear ", "left", "right", " vertical ", " level ", " top ", " bottom ", " interior ", " outer " be based on Orientation shown in the drawings or position relationship, it is for only for ease of description the utility model, rather than instruction or the dress for implying meaning Put or element there must be specific orientation, with specific azimuth configuration and operation, therefore it is not intended that to the utility model Limitation.
