Abstract

The utility model discloses a back roller of a concrete batcher with a split type bearing chamber, which comprises a roller pipe and a roller axle, wherein the roller pipe is together assembled with the roller axle by a bearing seat and a bearing arranged on pipe openings of both ends of the roller pipe. The bearing seat is composed of annular vertical boards welded on inner walls of both ends of the roller pipe, and a bearing box fixed on center holes of the vertical boards by bolts. The bearing is arranged in the bearing box. Both ends of the back roller of the utility model use a split type structure. The mode of the combining assembly of the annular vertical boards and the bearing box is used for replacing an original entire cast iron bearing chamber. The vertical boards and the bearing seat are separately manufactured for material saving and casting cost saving, the weight is correspondingly reduced and the installation is convenient. The vertical boards are directly welded into the roller pipe of the back roller. The utility model replaces the original mode of using screws for fixing the cast iron bearing chamber. The problem of the loosening disconnection of the screws does not exist, and supporting force is uniform.

Description

Has roller behind the batching plant of split type bearing chamber

Technical field

The utility model relates to construction machinery equipment, roller behind particularly a kind of batching plant.

Background technology

The two ends of roller need running in bearings behind the batching plant, therefore need behind proportioning machine, the two ends of roller be installed by bearing chamber, the bearing chamber on the roller is made after processing by the ironcasting of major diameter, big thickness behind the proportioning machine at present, bearing chamber by whole be bumped into the back roller the roller pipe in, on the circumference of roller pipe, radially penetrate 6 sunk screws bearing chamber fixed.All-in-one-piece cast-iron chock takes material very much, because cast-iron chock weight is very big, dismounting is cumbersome, and in machine works, and 6 sunk screws that radially are provided with are shaken and centrifugal action can become flexible gradually, even comes off and cause the accident.

The utility model content

The purpose of this utility model is to provide roller behind a kind of batching plant with split type bearing chamber, makes that the bearing chamber cost reduces, the convenient mounting or dismounting of bearing chamber, and the working stability of back roller is reliable.

The technical solution of the utility model is: roller behind a kind of batching plant with split type bearing chamber, comprise roller pipe, roll shaft, bearing block and bearing and the roll shaft of roller pipe by the installing of its two ends mouth of pipe is assembled together, described bearing block is to be made of the bearing box by bolting on the centre bore of the annular riser of roller pipe two ends inwall welding and riser, and described bearing is inlaid in the bearing box.

The port of described bearing box tightens and is equipped with bearing (ball) cover.

Split-type structural is adopted at roller two ends, back of the present utility model, replace original whole cast iron bearing chamber with the riser of annular and the mode of bearing box combination assembling, riser separates to make with bearing block not only can be saved material but also can save the casting cost, and the also corresponding minimizing of weight is easier for installation; Riser is directly to be welded in the roller roller pipe of back, has replaced original mode of fixing with screw and cast iron bearing chamber, do not have the screw loosening problem that comes off, and support force is more even.

The specific embodiment

As shown in Figure 1, roller behind a kind of batching plant with split type bearing chamber of the present utility model, comprise roller pipe 4, roll shaft 8, roller pipe 4 is assembled together with roll shaft by the bearing block and the bearing 5 of its two ends mouth of pipe installing, innovative point of the present utility model is: bearing block is to be made of the bearing box 2 by bolting on the centre bore of the annular riser 3 of roller pipe 8 two ends inwall welding and riser 3, bolt is made up of screw 6 and nut 7, bearing 5 is inlaid in the bearing box 2, and the port of bearing box 2 tightens and is equipped with bearing (ball) cover 1.

Claims

1, roller behind a kind of batching plant with split type bearing chamber, comprise roller pipe, roll shaft, bearing block and bearing and the roll shaft of roller pipe by the installing of its two ends mouth of pipe is assembled together, it is characterized in that: described bearing block is to be made of the bearing box by bolting on the centre bore of the annular riser of roller pipe two ends inwall welding and riser, and described bearing is inlaid in the bearing box.

2, roller behind the batching plant according to claim 1 is characterized in that: the port of described bearing box tightens and is equipped with bearing (ball) cover.
