Description

  The present invention is used in a track agitator having a charging hopper to maintain ready-mixed concrete in a drum in a suitable state.

  When producing ready-mixed concrete, for example, in order to satisfy the requirements such as strength and slump defined by JIS standards, it is required to reduce the error in the allowable measurement of ready-mixed material as much as possible. In addition, there is a standard for the quality of water to be used. For example, when water other than tap water is used, it must conform to a predetermined quality standard.

The ready-mixed concrete manufactured in the factory in compliance with these standards is transported to a work site by a truck agitator equipped with a drum. When putting ready concrete into the drum of the track agitator, a funnel-shaped charging hopper is used. The charging hopper is fixed to the vehicle body, and one end of the charging hopper is inserted into the drum. And when ready-mixed concrete is poured from the input opening opened to the upper part of the said input hopper, the said ready-mixed concrete will be thrown in in a drum through the receiving port opened to a drum (for example, refer patent document 1).
JP 2003-89109 A

However, the input port of the input hopper is normally opened by about 0.6 m ² , and rainwater or the like enters the drum from the input port when it rains, and is manufactured in compliance with the standards at the factory. Even the ready-mixed concrete deviates from the standards due to the intrusion of rainwater and the like.

  Further, when the ready-mixed concrete is put into the drum of the track agitator, the ready-mixed concrete adheres to the rear end portion of the charging hopper and the drum, and when these are cleaned using a high-pressure pump installed in the track agitator. The washing water flows into the drum through the charging hopper. Therefore, the hopper and the like must be cleaned after transporting and unloading the ready-mixed concrete, and if the transport time is long or the mortar that has adhered has hardened in the summer, There was a problem that the cured mortar had to be removed.

  Furthermore, the fluidizing agent to be added to the ready-mixed concrete is also charged into the drum via the charging hopper. However, in this charging method, the fluidizing agent can be charged only in the vicinity of the charging hopper. The agitation time required for mixing with ready-mixed concrete becomes longer.

  In addition, when introducing the fluidizing agent, it is necessary to use a safety belt because it is necessary to perform work at a height of 2 m or more from the ground. Annoying and dangerous.

  Therefore, the present application relates to a drum agitator including a drum having an opening for receiving ready-mixed concrete and a charging hopper having an opening for communicating with the receiving opening of the drum. And the communication port of the charging hopper are in communication with each other, separating the charging posture that enables charging of the ready-mixed concrete into the drum using the charging hopper, and the receiving port of the drum and the communication port of the charging hopper, It is characterized in that it can be selected from a separation posture that allows discharge from the communication port of the input hopper to be discharged to a discharge chute.

  Here, in the present specification, the term “ready concrete” is not limited to the ready-made concrete in a narrow sense, but is a concept that broadly indicates what is transported using a truck agitator. That is, it is a concept that includes mortar that does not include coarse aggregate.

  Accordingly, when the ready-mixed concrete is transported, except when the ready-mixed concrete is inserted into the drum, the separation posture is maintained, so that rainwater or the like can be prevented from entering the drum via the charging hopper. It becomes possible to maintain the quality of concrete suitably. Further, waste such as rain water and washing water discharged from the charging hopper can be discharged using the discharge chute. Further, immediately after the ready-mixed concrete is put in, it can be cleaned before the ready-mixed concrete adhering to the input hopper is hardened as a separating posture.

  Specifically, in the separation posture, it is desirable that the communication port of the input hopper is positioned above the discharge chute.

  And in the separation posture, it is possible to change the separation width between the receiving port of the drum and the communication port of the charging hopper, so that it is suitable for various situations such as when transporting or when adding a fluidizing agent. The posture can be selected.

  In addition, in order to reduce dangerous work at high places, such as when the charging hopper is washed, the drum receiving port and the communication port of the charging hopper are separated in a separated posture, and the charging hopper is separated from the charging hopper. It is conceivable that the height position of the charging port for charging the ready-mixed concrete can be moved to a position lower than the height position of the charging port of the charging hopper in the charging position.

  Further, by separating the communication port of the charging hopper from the receiving port of the drum along the direction of the rotation axis of the drum, a smooth separation operation can be realized.

  Furthermore, in the separation posture, by providing a rainproof cover that covers the receiving port of the drum, rainwater and the like can be prevented from entering from the receiving port of the drum.

  In addition, in order to improve the operability for the operator, an operation means for operating the drum receiving port and the communication port of the charging hopper to be separated is provided on either the driver seat or the rear side of the vehicle body. It is desirable to provide one or both.

  According to the present invention, when the ready-mixed concrete is transported or the like, the separation posture is maintained, so that rainwater or the like can be prevented from entering the drum via the charging hopper, and the quality of ready-mixed concrete can be improved. Can be maintained. Further, waste such as rain water and washing water discharged from the charging hopper can be discharged using the discharge chute. In addition, the charging hopper and the like can be cleaned as a separated posture immediately after the ready-mixed concrete is input, and the cleaning operation can be facilitated without the need for a suspending operation. Furthermore, since the ready-mixed concrete can be transported after washing, there is no risk of contaminating the roadside.
