Description

  The present invention relates to a tank tilting device, and in particular, when a fluid such as an insecticide in a tank is pumped out by a pump through a hose, the tank is automatically tilted and remains when the fluid in the tank decreases. The present invention relates to a tank tilting device that collects liquid at a corner at the bottom of the tank and makes it easy to suck the residual liquid with the hose, thereby reducing the residual liquid as much as possible and eliminating waste.

  In general, the water supplied to the plant on the farm, or the insecticidal solution sprayed on the plant, the oil to be sent to the factory, gasoline, or the drinking water given to the animal is contained in the tank T, and this is shown in FIG. In some cases, the fluid in the tank T is transported far by J, and the fluid in the tank T is sucked by a pump through the hose H and collected on site.

  In this case, if the fluid in the tank T decreases during collection and only a small amount remains horizontally at the bottom of the tank T, it becomes difficult to suck the fluid with the hose H.

  Therefore, conventionally, as shown in FIG. 6, the operator manually tilts the tank T on the automobile J to collect the fluid at the bottom corner of the tank T, facilitates the suction by the hose H, and prevents the fluid from remaining. Less and no waste.

  However, if the worker manually tilts the tank T as described above, the operability is poor and there is a risk that the worker may fall.

  In order to solve this problem, for example, a tank tilting device disclosed in Patent Document 1 has been developed.

  This tank tilting device automatically tilts a drum-like tank containing a fluid, and includes a base, a tank mounting base that is pivotally attached to the left and right sides of the base, and the tank mounting. It is composed of a column member that stands up at the rear part of the mounting table, and a spring that is laid between the rear end part of the base and the column member and constantly pushes up the rear end part of the mounting table. .

According to this tank tilting apparatus, when the fluid in the tank is recovered and the total weight of the tank and the fluid becomes light, the column member and the mounting table are tilted by the spring, whereby the tank on the mounting table is moved. The tank is automatically tilted, and the fluid in the tank is collected at the corner at the bottom of the front side of the tank to improve the suction of the fluid by the hose and to reduce the residual liquid as much as possible.
JP 2002-316727 A (see drawings and abstract)

  However, the above-described conventional technique is excellent in that the inclination angle can be adjusted by the ratio of the residual liquid in the tank, but improvement of the following problems is desired.

  Since the conventional tank tilting device is intended for a rectangular drum tank having a seat height higher than the size of the bottom surface, when the tank mounting table is tilted, the tank falls to the front side of the tank mounting table. It is likely and dangerous.

  Therefore, in order to prevent the tank from overturning, it is necessary to stand up the column member corresponding to the seat height of the tank and to support the tank with this column member.

  For this reason, the structure in which the column member is erected is complicated and inferior in workability and assembly.

  Further, when the tank is not mounted, the pillar member and the spring are projected to the outside and are bulky, so that the appearance is bad, obstructing, inconvenient to transport and store, and the operator may be caught.

  Furthermore, in the prior art, since the tank is fixed only by the tank upper edge stopper for preventing the tank from dropping, which is attached to the upper part of the column member, depending on the shape of the tank, it catches on the upper edge of the tank. There is a risk that the tank will fall off the tilting device due to lack of or lack of catch.

  Accordingly, an object of the present invention is to provide a tank tilting device that is simple in structure, compact, smart in appearance, excellent in workability and assemblability, easy to transport and store, and that can be safely operated by an operator. It is to be.

  In order to achieve the above object, one means of the present invention includes a fixed base, a tank support base that is rotatably coupled to a front end side portion of the fixed base via a hinge, and a rear end of the tank support base. And an urging means that is interposed between the rear end of the tank and the fixed base opposite to the upper end of the tank support, and pushes the rear end of the tank support upward at all times. And a tank holding means provided on the side of the tank support.

  In this case, the fixed base is configured as a rectangular frame with front and rear frames and left and right side frames, and the tank support base is between the front and rear frames, the left and right side frames, and the front and rear frames and the side frames.

When it becomes lighter, the above-mentioned urging means 16 pulls down the tip end side of the tank support 12 and rotates it using the left and right side bearings 14 as fulcrums.

  For this reason, the fluid in the tank collects at the corner at the bottom of the tank and is easily collected by the hose. Therefore, it is possible to prevent the fluid from being sucked and to recover the fluid up to the entire amount or close to the entire amount, thereby preventing waste of the fluid.

  H Similarly, since the fixed base 11 is provided with a pedestal 17 facing the rear end portion of the tank support base 12, the tank support base 12 is supported by supporting the tank support base 12 when the tank is placed on the tank support base 12. Can be held horizontally.

  I Similarly, since the stopper 18 is erected at the tip of the tank support 12, the stopper 18 prevents further movement of the tank even if the tank slips, and a tank holding plate 19 is provided on the tank support 12. Therefore, the holding plate 19 can prevent the tank from falling or falling from the side of the tank support 18.

  An embodiment of the present invention will be described below with reference to the drawings.

  FIGS. 1 to 3 show a first embodiment corresponding to the inventions of claims 1 to 3, and FIGS. 4 and 5 show a second embodiment corresponding to the inventions of claims 4 and 5, respectively. The form is shown.

The tank tilting apparatus according to these embodiments is applied to automatically tilt a tank T containing a fluid, for example, a disinfecting liquid sprayed on farm plants. The basic structure of the tank tilting apparatus according to the first embodiment is the fixed base 1 and the tip side portion of the fixed base 1, which is particularly suitable for the use of a tank T whose seat height is lower than that of a drum can or the like. The tank support 2 is interposed between the tank support 2 that is rotatably coupled to the base 3 and the rear end of the tank support 2 and the rear end of the fixed base 1 facing the tank support 2. Energizing means 4 that always pushes the rear end of the base 2 upward, a stopper 6 raised at the tip of the tank support 2, and tank holding means 7 provided on the side of the tank support 2 It consists of

  And the said fixed stand 1 is comprised by the front-and-rear frames 1a and 1b and the right-and-left side frames 1c and 1d at the rectangular frame.

  In addition, the tank support is a grid-like reinforcement frame 2e, 2f constructed between the front and rear frames 2a, 2b, the left and right side frames 2c, 2d, and the front and rear frames 2a, 2b and the side frames 2c, 2d. It is comprised with the frame which consists of.

  Further, the urging means 4 includes an upper bracket 4b provided on the left and right side frames 2c and 2d of the tank support base 2, and a lower bracket 4c slidably attached to the left and right side frames of the fixed base 1. The upper bracket 4b and the lower bracket 4c are respectively interposed between the lower bracket 4c and the rear frame 1b of the fixed base 1 with a link 4d rotatably supporting upper and lower ends. Thus, the lower bracket 4c is always pulled to constitute the link 4d to stand up.

  Further, an urging assisting means 5 that constantly pushes up the tank supporting base 2 in parallel with the urging means 4 is provided between the fixed base 1 and the tank supporting base 2.

  Brackets 9 and 10 are attached to the rear frames 1b and 2b of the fixed base 1 and the tank support base 2, respectively, and a hook 8 made of a chain or the like that is detachably hooked between the brackets 9 and 10 is provided. Therefore, by engaging the hook 8 with the bracket 10, the tank support 2 can be kept horizontal when the tank T is mounted horizontally with the disinfectant or the like in the tank T. Thus, the tank T is kept horizontal and stable.

  The hook 8 can be hooked on a hook or the like provided on the vehicle chassis to hold the tank tilting device so as not to move.

  The fixed base 1 and the tank support base 2 are formed in a frame shape as described above. However, the shape is not limited to this, and for example, a plate shape may be used. This is not limited as long as the strength that can withstand the load when it is satisfied is obtained. In particular, the reinforcing frames 2e and 2f are formed in a lattice shape, but the shape is not limited to this.

  Next, with respect to the form of the urging means 4, as shown in FIG. 3, the upper bracket 4 b provided on the rear outer surface of the left and right side frames 2 c, 2 d of the tank support base 2, and the left and right sides of the fixed base 1. A lower bracket 4c slidably attached to a rail 4f provided on the side frames 1c and 1d via a roller 4e, and a link 4d rotatably supported by the upper bracket 4b and the lower bracket 4c, respectively. A tension spring 4a is interposed between the rear frame 1b of the fixed base 1 and the lower bracket 4c.

  In order to efficiently lift the rear side of the tank support 2 by the lever principle, it is desirable that the urging means 4 be installed at a position away from the hinge 3. Any rear part may be attached.

  The urging means 4 is provided at two positions behind the fixed base 1 and the tank support base 2, but it may be provided at one place as long as sufficient urging force can be obtained to incline the tank T, and attached at two or more places. May be.

  Further, although the coil spring 4a is used as the tension spring, other springs may be used, and rubber or other similar elastic bodies may be used.

  Moreover, although the rail 4f is attached in order to slidably attach the lower bracket 4c, another method such as digging a groove in the side frame of the fixed base frame 1 may be used.

  In the above embodiment, the upper end of the link 4d is pivotally attached to the upper bracket 4b via a shaft. However, for example, from the side surface opened to the upper part of the link 4d. A U-shaped notch groove may be formed, and the shaft may be inserted into the notch groove. As a result, the link 4d can be detachably attached to the upper bracket 4b, and when the link 4d is removed from the upper bracket 4b, the tank support 2 can be easily loaded without applying a load. 1 and the tank support 2 can be made horizontal, and convenience in stacking and tilting tank tilting devices is improved.

  Next, as shown in FIG. 1, the tank holding means 7 is connected to an arbitrary position of the left and right side frames 2c and 2d and the bracket 7a provided on the lattice frame 2f and the bracket 7a. And tank fastening means 7b made of a belt, wire or string.

  The tank holding means 7 does not necessarily need to be a belt, a wire, or a string, and is not limited to this as long as sufficient strength can be secured to fix the tank. The tank holding means 7 may be a tank holding means 19 provided with tank holding plates 19a and 19b on the side surfaces of the tank support frame as shown in FIG. 4 described later, and both the tank holding means 7 and 19 are connected to each other. You may use together.

  Next, with respect to the urging assisting means 5, as shown in FIG. 3, the auxiliary spring bracket 5b standing at the rear end portions of the left and right side frames 2c and 2d of the tank support base 2, and the bracket 5b and the tank It consists of auxiliary springs 5a interposed between the left and right side frames 1c and 1d rear end portions of the fixed base 1. Preferably, the protective spring 5a is protected by a protective cover 5c so as not to be buffered by the fixed frame 1 or the auxiliary spring bracket 5a when the auxiliary spring 5a expands or contracts.

  The urging assisting means 5 is provided at two rear end portions of the fixed base 1 and the tank support base 2 in parallel with the urging means 4, but the mounting positions are not necessarily two, and are necessarily attached. There is no need. Further, although the coil spring is used as the elastic body, other known elastic bodies may be used.

  When the fluid in the tank T is full, the tank support 2 is pushed downward by the load due to the weight of the tank and the fluid in the tank, and the tank support 2 is rotated clockwise via the hinge 3 as shown in FIG. It will be in the horizontal state as shown.

  At this time, the biasing assisting means 4 is compressed, and at the same time, the link 4d rotates in the clockwise direction against the spring 4a and becomes almost horizontal.

  During this operation, the lower bracket 4c slides the roller to the left and right side portions of the fixed base 1 through 4e, and the spring 4a extends to increase the tension.

  That is, when a load is applied to the tank support 2 by the tank and the fluid in the tank, the link 4f is pushed down, and the lower bracket 4c that is rotatably attached to the link 4f slides through the roller 4e. The spring 4a attached to the lower bracket 4c extends to the left and right sides with a stored energy restoring force. At the same time, the auxiliary spring 5a provided on the tank support 2 via the auxiliary spring bracket 5b contracts with a stored energy restoring force.

  When the amount of liquid remaining in the tank decreases, the weight decreases and the load on the tank support 2 decreases. For this reason, the tank support is first pushed up by the stored energy restoring force of the spring 5a as the biasing assisting means, and then the lower bracket 4c is pulled to the rear end side by the restoring force of the spring 4a in the biasing means 4, Therefore, the link 4d stands up while rotating counterclockwise, pushes up the rear end side of the tank support 2 and rotates it counterclockwise via the hinge 3 to be inclined.

  In this case, the urging assisting means 5 can be operated without it, but it is preferable that it is present in order to increase the speed.

  In the above operation, the lower bracket 4c slides rearward on the rail 4f, and the lower bracket 4c and the link 4d that is rotatably attached rise up in the vertical direction so that the upper bracket is attached to the tank support base 2. 4b is pushed up and becomes an urging force that pushes up the rear frame 2b of the tank support 2.

  The basic structure of the tank tilting apparatus according to the second embodiment is coupled to a fixed base 11, a rotary shaft 13 rotatably attached to a bearing 14 provided on the fixed base 11, and the rotary shaft 13. The tank support 12 facing the fixed base 11 and the left and right sides of the tank support 12 are interposed between the left and right sides of the fixed base 11 and the left and right side parts of the tank support 12. Urging means 16 that always pulls the portion downward, a stopper 18 raised at the front end of the tank support 12, and a rear end of the tank support 12 provided on the rear end of the fixed base 11. And a tank holding plate 19 standing on the left and right sides of the tank support 12.

  In this case, the rotating shaft 13 is attached to a position shifted from the center of gravity of the tank support 12 to the front end side, and brackets 23 and 24 are erected on the left and right sides of the fixed table 11 and the left and right sides of the tank support 12, respectively. The urging means 16 comprising a coil spring is provided between the brackets 23 and 24.

The shapes of the fixed base 11 and the tank support base 12 are not limited to the shapes shown in the drawings as long as the strength capable of withstanding the load when the tank is filled with fluid is obtained.
In addition, although a spring is used as an urging means for pulling the front frame 12a of the tank support base 12 downward, a known rubber or other elastic body similar to the spring may be used.

  In order to pull the right and left side portions, which are the front side of the tank support base 12 efficiently, it is desirable that the mounting position of the urging means 16 is separated from the rotating shaft 13, but the urging means 16 is attached as necessary. It is possible to change the position and the amount of installation.

  Brackets 21 and 22 are attached to the rear frames 11b and 12b of the fixed base 11 and the tank support base 12, respectively, so that the level is maintained stably when the tank is horizontally loaded with the fluid in the tank T. , 22 is preferably provided with a hook 20 that is detachably hooked.

  Next, as shown in FIG. 4, the tank holding means 19 is composed of a pair of tank holding plates 19a and 19b standing on the left and right side frames 12c and 12d of the tank support base 12.

  The tank holding means 19 does not necessarily need to be a pair of tank holding plates. Like the previous embodiment shown in FIG. 1, a tank fastening means such as a bracket and a belt, a wire, or a string coupled thereto is used. It may be used.

  When the fluid is full, the tank support 12 is in a horizontal state as shown in FIG. 5 due to the load of the tank T and the fluid in the tank. That is, when a downward load is applied to the tank support 12 by the tank T and the fluid in the tank, the installation position of the rotating shaft 13 of the tank support 12 is in front of the center of gravity of the tank support 12. Therefore, when the front of the tank support 12 is lifted upward, the spring which is the urging means 16 is extended with a stored energy restoring force, and at the same time, the rear is pushed downward and abuts against the pedestal 17 to stabilize. Therefore, the tank support 12 is parallel to the fixed base 11 and the tank is placed horizontally.

  When the amount of liquid remaining in the tank decreases, the spring is contracted by the accumulated return force of the spring as the urging means 16, and the left and right sides of the tank holding base 12 connected to the spring are pulled downward and rotate. The tank support 12 is tilted when the rear side is lifted upward with the shaft 13 as a fulcrum.

  For this reason, the fluid in the tank gathers at the bottom corner of the tank T, for example, and it is easy to suck the fluid with the hose.
