The specific embodiment

Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described further.

As shown in Figures 1 to 4, dust hopper of the present utility model comprises bucket body 1 and plug 2, at bucket body 1 by being for example that four symmetrically arranged elastic links 4 liftably mount on support 5, the top of bucket body 1 has the inlet point entered for material, the bottom 12 of bucket body 1 is funnel type, and 12De bottom, bottom has discharge openings 121.Plug 2 is fixedly installed on support 5, and be positioned at the inside of bucket body 1, plug 2 comprises valve portion 212 as shown in Figure 4, respectively upper, upper guide part 211 and the lower guide part 213 that accept mutually with valve portion 212 below, the diameter of valve portion 121 is greater than,

lower guide part

211, 213 diameter, valve portion 212 be positioned at lower edge on horizontal surface and the inwall of bottom 12 fits under the effect of elastic link 4, at this, being interpreted as is situation about being under the off working state of unloaded material, space between upper guide part 211 and bucket body 1 forms annular material storing cavity, lower guide part 213 forms with the space between bucket body 1 the annular discharging chamber communicated with discharge openings 121.At this, the quantity of elastic link 4 and position with guarantee bucket body 1 reposefully lifting be as the criterion.According to above structure, carrying out along with blanking, the aperture area of dust hopper will be closed gradually along with the progressively rising of bucket body 1, until while completing blanking, the lower edge of the inwall of bottom 12 and valve portion 212 is being drawn under effect and is being fitted on elastic link 4, the opening of dust hopper completes closure, recovers sealing state.

In order to guarantee the reliability of the sealing between bucket body 1 and plug 2, the center shaft of bottom 12 is crossed the center of the lower edge of valve portion 212.For the embodiment shown in Fig. 1 to 4, bucket body 1 and plug 2 are swivel, as long as when mounted the coaxiality error of the two is controlled in rational scope, at this, the error of right alignment can be limited in the scope of 0.05mm～0.1mm usually.In the present embodiment, the main body of upper guide part 211 can be taper shape, and the main body of lower guide part 213 can be turbination, and the cone angle of lower guide part 213 is greater than the cone angle of bottom 12, so that carry out blanking.

For the ease of regulating according to actual needs the height of plug 2, plug 2 can by erecting frame 3 adjustable-heights be fixedly installed on support 5, what erecting frame 3 comprised that horizontal adapter plate 32 and an end and horizontal adapter plate 32 be connected is for example two symmetrically arranged connecting arms 31, the other end of each connecting arm 31 passes and corresponding separately mounting hole 15 and support 5 that arrange on bucket body 1 and is connected, as can be known according to the principle of work of dust hopper, the dimensional characteristic of this mounting hole 15 can not hinder relative plug 2 liftings of bucket body 1.On horizontal adapter plate 32, be provided with the tapped bore of up/down perforation, the threaded shank 22 that the end face with upper guide part 211 of plug 2 is connected is connected with the tapped bore screw thread fit of horizontal adapter plate 32, and is locked by upper and lower jam nut 24a, the 24b that lays respectively at horizontal adapter plate 32 above and belows.

This bucket body 1 can be formed in one, also can be formed by connecting by a plurality of parts, in the present embodiment, this bucket body 1 comprises 14, bottom, top 12 and is connected in the pars intermedia 11 between upper and lower part, top 14 can be the trumpet type closed up in upper end, and the exit skirt on top 14 is above-mentioned inlet point.

For bucket body 1, be the embodiment of swivel, this pars intermedia 11 can be cylindrical, can with fastener, be fixedly connected with by upper butt flange between pars intermedia 11 and top 14, and pars intermedia 11 can be fixedly connected with other fastener by lower butt flange with bottom 12.For the bucket body of this kind structure, an end of elastic link 4 is fixedly connected with support 5, and the other end can be fixedly connected with lower butt flange.

Elastic link 4 can comprise screw rod, lower screw rod and by the spring be mounted between upper and lower screw rod that coordinates between hook and link, upper screw rod is threaded with support 5, and is locked by the first upper and lower jam nut that lays respectively at support 5 above and belows; Described lower screw rod is threaded with lower butt flange, and is locked by the second upper and lower jam nut that lays respectively at lower butt flange above and below, wherein, between the second upper and lower jam nut and lower butt flange, packing ring can be set.

In order to limit the maximum downstream distance of bucket body 1, the assurance elastic link is worked in suitable deformation range, between this elastic link 4 and support 5, can be connected the chain be used to the maximum downstream distance that limits bucket body 1, wherein, the length of chain depends on the maximum downstream distance of setting, and those skilled in the art can select as required.

The foregoing is only preferably embodiment of the utility model, not be used for limiting practical range of the present utility model, the equivalence of in every case doing in protection domain of the present utility model changes and modifies, and all should think and fall in protection domain of the present utility model.
