Description

  The present invention relates to a garbage truck that collects and transports garbage, and more specifically, the collected garbage is pulverized on the spot, so that the pulverization and separation work at the bagging / processing plant before collection can be omitted. It relates to garbage crushing vehicles.

Conventionally, garbage such as food residues discharged from food factories and restaurants is once packed in a vinyl bag, collected by a garbage truck, transported to a treatment plant, and incinerated at the treatment plant. Accordingly, there is a problem in that a vinyl bag is separately required for disposal, which is costly and troublesome, bulky and inefficient during transportation, and incinerated at the treatment plant, making it impossible to regenerate food resources.
JP 2004-299812 A

  The problem to be solved by the present invention is to solve these conventional problems, eliminate the need for bagging into vinyl bags and separation / pulverization for resource recycling, and to increase disposal costs and transport efficiency. An object of the present invention is to provide a garbage crushing and transporting vehicle.

The configuration of the present invention that solves this problem is as follows.
1) A crusher for crushing garbage is installed in the tank vehicle body. A hose with a three-way valve in the middle is connected between the crusher and the tank, and the hose is located between the three-way valve and the tank. A delivery / exhaust pump that sends and discharges items to and from the tank is installed, a discharge hose is installed at the switching destination of the three-way valve, and the collected garbage is crushed on the spot and stored in the tank so that it can be transported. The garbage pulverizing and transporting vehicle 2) characterized in that the pulverizer is installed so as to be inclined so that the hose connection side is downward, and the pulverized material in the pulverizer is easily discharged to the hose by the inclination. Garbage crushing and transporting vehicle 3) The tank is provided so as to be separated from the vehicle body by an inclination, and the pulverized material in the tank can be easily discharged by the inclination. Accommodates with such load And with a metering device for metering the weight of the pulverized product, the 3) in garbage pulverizing truck according.

  According to the present invention, since garbage is directly pulverized and transported at the collection site, it is possible to omit the bagging operation into the vinyl bag at the time of disposal and the separation operation at the processing site. Further, the volume is reduced by omitting the vinyl bag and pulverizing, and the garbage corresponding to the original volume of the tank can be efficiently transported without being bulky.

  In the present invention, it is preferable that the pulverizer is installed so as to be inclined so that the hose connection side is downward, because the pulverized material in the pulverizer is easily discharged to the hose by the inclination, and the work can be efficiently performed. In addition, it is preferable that the tank be provided so as to be separated from the vehicle body by an inclination, because the pulverized material in the tank can be easily discharged by the inclination, and the work can be performed efficiently. The vehicle body may be provided with a measuring device that measures the weight of the pulverized material accommodated by the load applied to the vehicle body when the tank is separated, and the weight may be measured when collecting garbage. Embodiments of the present invention will be specifically described below with reference to the drawings.

  As shown in FIGS. 1 and 2, the garbage pulverizing and transporting vehicle 1 of this embodiment is provided with a tank 3 on a chassis frame 2 so that the tank 3 can be tilted up and down, and a pulverizer 4 is installed at the rear of the chassis frame 2. Then, a hose 5 provided with an electric three-way valve 6 in the middle position is connected between the pulverizer 4 and the tank 3, and the pulverized product B is tanked at the position of the hose 5 between the three-way valve 6 and the tank 3. 3 and a discharge pump 7 for discharging from the tank 3 is provided, and a discharge hose 8 is connected to the switching destination of the three-way valve 6.

  As shown in FIG. 3, the pulverizer 4 supports a rotating blade 4 d that is rotated by a motor 4 g in a cylindrical body 4 a at the bottom, and forms a discharge port 4 c on the lower side surface of the cylindrical body 4 a to be connected to the hose 5. The lid 4b is attached to the upper surface of the cylindrical body 4a so as to be freely opened and closed. The pulverizer 4 is installed on the chassis 4 with the base 4f so as to be inclined so that the discharge port 4c side is downward.

  The delivery pump 7 is a single-shaft eccentric screw pump. As shown in FIG. 4, a motor output shaft 7b is disposed at one end of a casing 7a, and a male screw rotor 7d is connected to the output shaft 7b via a flexible shaft 7c. The internal thread-shaped stator 7e is formed on the inner wall of the casing 7a where the externally threaded rotor 7d is arranged, and the external threaded rotor 7d is rotated eccentrically within the internally threaded stator 7e by forward and reverse rotation of the motor so that the pulverized product B can be sent and discharged. I have to. The operation parts of the three-way valve 6 and the delivery pump 7 are installed in the driver's seat (not shown).

  A load cell 9 is attached to the rear end of the tank 3 as shown in FIG. 5A, and is pivotally supported on the chassis frame 2 by a pin 9a. The load cell 9 is pivotally supported by the lower portion of the tank 3 and placed on the chassis frame 2. A subframe 3a is attached, and an elevating device 10 that tilts the tank 3 by expansion and contraction by a hydraulic cylinder is pivotally supported between the front upper portion of the tank 3 and the chassis frame 2 as shown in FIG. The load cell 9 is attached to the shaft support at the lower end of the. In FIG. 5A, the hose 5, the three-way valve 6, and the discharge hose 8 are omitted.

  In this embodiment, as shown in FIG. 6, the garbage A is stored in a plastic bucket or the like. The pulverization capacity is charged and the operation unit 4e is driven. The garbage A is pulverized for a certain time in the cylindrical body 4a by the rotation of the rotary blade 4d, and at this time, the volume is reduced to about ½ compared to before pulverization.

  When pulverized sufficiently, the three-way valve 6 is switched to the hose 5 side, the pulverizer 4 is stopped, and the delivery pump 7 is driven to rotate forward. The pulverized material B in the cylindrical body 4 a is discharged to the hose 5 by the inclination of the cylindrical body 4 a and the negative pressure by the feed / discharge pump 7, and sent into the tank 3 through the hose 5. Subsequently, the remaining garbage A is pulverized by the pulverizer 4 and sent to the tank 3, and this process is repeated to collect all the garbage A. After the collection, as shown in FIG. 1B, the tank 3 is tilted by the lifting device 10 and the weight of the crushed material B in the tank 3 is measured by the front and rear load cells 9.

  After transporting to the treatment plant, the three-way valve 6 is switched to the discharge hose 8 side, and the feed / discharge pump 7 is driven in reverse rotation. The pulverized product B in the tank 3 is turned from the hose 5 by the three-way valve 6 by the negative pressure by the delivery pump 7, sent to the discharge hose 8, and discharged outside. Since the discharged pulverized product B has already been crushed, it becomes easy to turn into a food recycling resource after only dehydration without separate pulverization.

  As described above, according to the present embodiment, since garbage A is directly pulverized and collected at the collection site, it is possible to omit the bagging operation into the vinyl bag at the time of disposal and the pulverization / sorting operation at the processing site. Became. Further, the volume was reduced by omitting the vinyl bag and crushing, and the garbage A corresponding to the original volume of the tank 3 could be efficiently transported without being bulky.
