Description

Feeding tube for feed vehicle with adjustable length {Vehicle for distributing provender having a boom can be variable its length}

The present invention relates to a feed vehicle, and more particularly to a feed pipe of the feed vehicle that can be adjusted in length.

A typical feed vehicle is equipped with a storage tank and hydraulic equipment for releasing the contents to the outside, and transports a large amount of feed from a supply station or a factory to provide a unit consumer having a temporary storage such as a silo. Special vehicle to assist.

1 is a configuration diagram showing a schematic side view form and use state of a conventional feed vehicle. The basic structure for discharging the contents of the tank 100 is a fixed conveying part 2 'installed in the longitudinal direction at the bottom of the tank, an upright conveying part for conveying the contents conveyed backward by the fixed conveying part in the vertical direction. 4 'and an elongated main feeder 6', one end of which is connected to the end of the upright feeder and an outlet is provided at the other end. The other end of the main feeder 6 ′ faces the external reservoir 200.

The feed vehicle stops near the reservoir by reversing to feed the food loaded inside the fixedly installed reservoir 200 such as a silo, and then operates hydraulic equipment to discharge the contents of the tank. The main conveying pipe 12 'of the main conveying part 6' is in the position indicated by the dotted line in transport or normal condition, and when the load is loaded, the outlet port is turned toward the rear of the vehicle by rotating the upright conveying pipe 10 '. Will be. The main feed pipe 12 'can be hinged up and down about a part connected to the upright feed pipe 10' by a hydraulic cylinder connected to the vehicle body one end and the other end connected to the main feed pipe 12 'itself. It is supposed to be.

Since the main transport pipe 12 'has a specific length, the distance between the vehicle and the reservoir must be exactly matched. It is common to adjust the vehicle itself several times or back and forth in order to accurately match this distance. If the space around which the reservoir is installed is too small or there are many obstacles in the space, it is difficult to easily adjust the vehicle, which makes the basic setting work more difficult.

An object of the present invention for the above problems, to be able to vary the length of the main feed pipe to some extent to reduce the burden on the operator for the problem of position adjustment of the vehicle.

The above object is, as long as installed on the storage tank so as to discharge the feed in the storage tank spaced apart, the fixed tube having a drive screw rotatable by a hydraulic motor; Feeding tube of the adjustable feed vehicle, characterized in that it is fitted in the longitudinal direction at the end of the fixed tube, one end is connected by a hydraulic cylinder connected to the fixed tube and the feed outlet is provided at the tip end thereof. Is achieved by.

According to the present invention, the drive screw of the fixed tube is composed of a drive shaft made of a hollow pipe and a drive blade installed on the outer peripheral surface thereof; The variable tube is a driven shaft consisting of a driven shaft that is a part of the driven shaft that can be supported by being introduced into the drive shaft, and is installed in succession to the drive blade, but is attached to only a part of the outer peripheral surface of the driven shaft does not enter the drive shaft By including a screw, when the hydraulic cylinder is operated to apply a compressive force in the axial direction of the fixed tube and the variable tube, the driven screw is characterized in that the length can be varied by being superimposed with the drive screw while rotating.

Hereinafter, embodiments of the present invention will be described in more detail with reference to the accompanying drawings. Referring to Figure 2 will be described a structure capable of varying the length of the main feed pipe. Fig. 2 (a) (b) is sectional drawing cut along the longitudinal direction of the main feed pipe. 3 is a use state diagram showing an installation state. The configuration for carrying out the characteristic function of the feed vehicle is the storage tank 100, fixed feeder (2), upright feeder (4) and the main feeder (6). The present invention relates to a main transport pipe (12) constituting the main transport portion.

The feed pipe 12 of the main feeder 6 is composed of a fixed pipe 12a and a variable pipe 12b that is fitted to and connected to the front end thereof. The fixed tube 12a is installed in the upper portion of the storage tank 100 so as to discharge the feed in the storage tank 100 (see FIG. 3) to a spaced place, and is rotatable by a hydraulic motor (not shown). It has a screw 36. Variable tube 12b is fitted in the longitudinal direction at the end of the fixed tube 12a, one end is connected by a hydraulic cylinder 34 connected to the fixed tube and has a feed outlet 24 at the tip.

Since the basic operation or structure of the feed pipe 12 is not different from the conventional one, detailed description thereof will be omitted.

The fixed tube 12a and the variable tube 12b extend along the longitudinal direction in a piston manner by a hydraulic cylinder 34 whose one end is connected to the fixed tube 12a and the other end (piston part) is connected to the variable tube 12b. Or compressed. Hydraulic cylinder 34 is installed symmetrically to balance the force. The discharge port 24 is rotatably installed in the variable pipe 12b to adjust the discharge direction. The variable tube 12b has a diameter fitted to the outer circumferential surface of the fixed tube 12a, which facilitates the feeding of the feed.

The driving screw 36 rotated by the hydraulic motor 16 is installed in the fixed tube 12a, and the driven screw 38 freely rotated by the shaft bearing is installed in the variable tube 12b. The driving screw 36 and the driven screw 38 are the same shape so that they can overlap each other. That is, spiral blades 40 and 42 having the same shape are attached to the outer circumferential surfaces of the drive shaft and the driven shaft, respectively.

The drive shaft 44 of the drive screw is a hollow pipe, and a portion 46 ′ from the tip of the driven shaft 46 of the driven screw is a rod or pipe of a cross-sectional area which can be inserted into the drive shaft 44 of the drive screw. The tip of the driven shaft 46 is supported by a bushing 48 or a bearing which is fixed inside the drive shaft 44 while being inserted therein.

The tip portion section 38 ′ of the driven screw 38 has a shape in which a shaft and a blade are separated. In the state where the fixed tube 12a and the variable tube 12b are extended as much as possible (see FIG. 5 (a)), the driven blade 42 of the driven screw is pitched by a predetermined pitch at the tip of the drive blade 40 of the driving screw. You can make contact. In this state, when the hydraulic cylinder 34 is operated to apply a compressive force in the axial direction of the drive screw 36 and the driven screw 38, the driven screw 38 is rotated by the screw principle (the driving screw is a hydraulic motor). It is only rotated by the fixed state in this state) The blades 40 and 42 are overlapped with each other by the length of the reducing pipe (see FIG. 2 (b)). When the hydraulic cylinder 34 is expanded again, the variable screw 12b is drawn out from the fixed tube 12a while the driven screw 38 rotates. In this way, the length of the feed pipe 12 can be adjusted by the movement distance of the hydraulic cylinder 34. When the contents are pressurized by driving the driving screw 36, the contents are discharged to the outlet by rotating the driven screw 38. Reference numeral 50 is a guider for guiding each of the blades 40 and 42 to easily overlap each other.

The driven screw 38 of the variable tube 12b may be optional. That is, the screw may be provided only up to the fixed tube 12a and the variable tube 12b may be a hollow tube. Feed fed by the drive screw 36 is forcibly pushed to the variable tube can exit the outlet.

According to the above configuration, it is possible to vary the length of the conveying pipe to some extent to reduce the burden on the driver or operator for the problem of position adjustment of the vehicle in the field. This allows for quick and easy operation.
