Abstract
The utility model discloses a movable-type opening-closing mechanism for a sealing cover for the feed hopper of a concrete mixing and transporting truck, wherein rotary shafts (5) are arranged on the left sidewall and the right sidewall of the feed hopper (2), which are opposite to each other, respectively, rear cover shafts (3) are arranged at the left side and the right side of the rear end of an upper cover (4) respectively, and a turnover link (6) is connected between the rotary shaft (5) and the rear cover shaft (3) at the same side; an oil cylinder seat (7) is fixedly installed at the front end of the feed hopper (2), and the root part of the cylinder sleeve of an oil cylinder (8) is hinged on the front end part of the oil cylinder seat (7); a pull rod (9) is hinged at the rear end of the oil cylinder seat (7), and the other end of the pull rod (9) is hinged with the rear end of the upper cover (4); and the outer end of the piston rod of the oil cylinder (8) is hinged with the pull rod (9). Opening and closing of the upper cover of the feed hopper are improved to be performed by a link-type mechanism from the traditional cover turnover mode; and the moving height space of the upper cover in a cover opening-closing process is greatly reduced, and the opening height is small, so that the movable-type opening-closing mechanism is more suitable for working places with limited heights, such as tunnel construction.
Description
Technical field
The utility model relates to a kind of open-and-close mechanism of hooper door, specifically a kind of portable open-and-close mechanism of concrete mixing and transporting car feed hopper seal cover.
Background technology
The feed hopper of the mixing drum of present concrete mixing and transporting car is all with the opening made progress, and this opening is less than lid.The problem of bringing like this is: while 1, raining, can not stop entering of rainwater; 2, can not stop the convection current of air, be unfavorable for concrete insulation and can not stop concrete water evaporation.If can add the charging aperture lid, can address the above problem.
Common way is to be provided with convertible upper cover at opening part, and while uncapping, upper cover turns on one side jointed shaft.Its major defect is: the first, owing to being a side jointed shaft upset around lid, while uncapping the fluctuating of the peak of the movement locus of the other end of lid highly larger, when mixing plant is reinforced, working depth is limited, very inconvenient.The second, drive the hydraulic mechanism of uncapping generally to be arranged in feed hopper, frequently be subject to concrete and pollute and corrode, service life is shorter, and repair and maintenance inconvenience.
The utility model content
The utility model aims to provide a kind of portable open-and-close mechanism of concrete mixing and transporting car feed hopper seal cover, technical problem to be solved is, make the hydraulic drive mechanism of seal cover be placed on feed hopper, and the decrease Lift, to overcome the defect of existing flip-open cover mechanism.
The technical scheme that the utility model adopts is as follows:
A kind of portable open-and-close mechanism of concrete mixing and transporting car feed hopper seal cover, the feed hopper that comprises mixing drum, described feed hopper has opening upwards and is provided with upper cover, it is characterized in that: on the relative sidewall in two of the left and right of described feed hopper, be respectively arranged with a rotating shaft, the left and right sides, rear end of described upper cover is respectively arranged with a bonnet axle, between the rotating shaft of the same side and bonnet axle, is connected with the upset connecting rod; The front end of described feed hopper is installed with oil cylinder seat, in described oil cylinder seat, is provided with oil cylinder, and the cylinder sleeve root of described oil cylinder is hinged on the leading section of oil cylinder seat; The rear end of described oil cylinder seat is hinged with pull bar, and the other end of described pull bar and upper cover back-end are hinged; The outer end of the piston rod of described oil cylinder and described pull bar are hinged.
Good effect of the present utility model is:
(1), the folding of feed hopper upper cover is improved to link mechanism by traditional flip mode, in the process of folding lid, the mobile height space of upper cover is dwindled greatly, Lift is less, thereby working depth is lower when mixing plant is reinforced, more convenient operation, and be more suitable for the workplace limited in the constructing tunnel equal altitudes.
(2), be arranged on the outside of feed hopper for the hydraulic mechanism that drives the upper cover opening and closing movement, in the process that completes the action of expection opening and closing lid, avoided hydraulic mechanism to be polluted by concrete, the hydraulic part maintenance is easier, longer service life.
(3), open degree of the present utility model increases, charging efficiency is higher.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model (one), and what this figure showed is the closing lid state.
Fig. 2 is structural representation of the present utility model (two), and what this figure showed is the state of uncapping.
The specific embodiment
As shown in Figure 1, 2, the utility model comprises the feed hopper 2 that is arranged on mixing drum 1 top, rear end, the top of described feed hopper 2 is provided with upper cover 4, be respectively arranged with a rotating shaft 5 on two relative sidewalls of described feed hopper 2, the left and right sides, rear end of described upper cover 4 is respectively arranged with a bonnet axle 3, is connected with upset connecting rod 6 between the rotating shaft 5 of the same side and bonnet axle 3.
The front end of described feed hopper 2 is installed with oil cylinder seat 7, in described oil cylinder seat 7, is provided with oil cylinder 8, and the cylinder sleeve of described oil cylinder 8 is hingedly mounted on the leading section of oil cylinder seat 7.Described oil cylinder seat 7 rear ends are hinged with pull bar 9, and the other end of described pull bar 9 and upper cover 4 rear ends are hinged.
Also offer axis hole 10 on described pull bar 9, the axis hole 10 on the outer end of the piston rod of described oil cylinder 8 and described pull bar 9 is hinged by jointed shaft.
While uncapping, the piston rod of oil cylinder 8 outwards ejects pull bar 9, and upper cover 4 moves backward under the drive of pull bar 9, and under the support of connecting rod 6, upper cover 4 upwards rises simultaneously, until break away from the opening part of feed hopper 2 fully.Oil cylinder 8 counteragents are realized closing lid.
