Description

  The present invention relates to a joint spreader that spreads joints mainly on grass in golf courses and parks.

  Conventionally, in a place where a lawn is cured, such as a golf course, a park, or a riverbed, an operation of spraying soil for the purpose of growing the lawn is performed. Such work is usually performed by a joint spreader (see, for example, Patent Document 1 and Patent Document 2).

  At present, the spraying position is adjusted so that the joint soil can be sprayed accurately like the one described in Patent Document 1, and the one described in Patent Document 2 is stable from the bottom of the hopper. In order to be able to take out the soil, a rotating shaft having a spiral plate arranged at the bottom of the hopper is arranged in the front-rear direction, and the earth is actively taken out from the hopper by the rotation of the rotating shaft.

  However, in the joint spreader as described above, it is not always in a high fluidity state that the joint spread can be smoothly moved in the hopper and dropped from the hopper. That is, when the joint soil contains moisture unnecessarily, the joint soil may be fixed in a beam shape between the opposing wall surfaces that constitute the upper side of the bottom of the hopper. At that time, there is a problem that the joint spreader operates without spraying the joints in a state where a space is formed at the bottom of the hopper and in the vicinity thereof. When this happens, the spraying of the top soil is interrupted at a location unexpected by the user who is spraying the top soil, resulting in unevenness in the spraying of the top soil. In addition, in order to correct the dispersion unevenness caused in this way, in addition to the work of dropping the joint soil fixed to the hopper, the joint spreader is moved again to the place where it could not be dispersed due to the interruption and sprayed again. It is necessary to perform such a redo work. That is, the work efficiency is significantly reduced.

  This invention pays attention to such a malfunction, and it aims at providing the joint spreader which can continue the dispersion | distribution of the joint soil in operation | movement continuously and stably.

  In order to achieve such an object, the present invention takes the following measures.

  That is, the joint spreader according to the present invention includes a joint containing portion for containing the joint for spraying the grass on the inner surface, and a joint outlet for discharging the joint from the lower side of the joint containing portion to the outside. A hopper having a hopper, a spraying device for spraying the joint soil discharged from the joint soil discharge port to the ground, and the joint soil adhered to the inner wall of the hopper by vibrating the inner surface of the hopper during the operation of the spray device. And a vibration device to be dropped.

  If it is such, even if the joint soil accommodated in the hopper contains a lot of water, it is possible to effectively avoid the problem that the joint soil is stuck to the inner surface of the hopper. As a result, it is possible to effectively avoid the problem that the joint soil cannot fall from the upper part of the hopper. As a result, it is possible to provide a joint spreader capable of continuously and stably spreading joint soil during operation.

  Here, in many cases, the above-mentioned drop failure of the joints forms a general arch shape that bridges between the inner surfaces facing the joints above the hopper bottom. It was found that the formation of the arch shape is often seen on the inner side surface, particularly on the upward inclined surface facing obliquely upward. That is, in order to more effectively promote the movement of the joint soil by the vibration device, it is desirable that the vibration device vibrate an upward inclined surface that faces obliquely upward in the joint housing portion.

  Here, the configuration in which the upward inclined surface is vibrated is not necessarily limited to the aspect in which the vibration device is directly attached to the portion where the upward inclined surface is provided. That is, the concept includes various modes in which vibration generated by the vibration device can propagate to the upward inclined surface.

  Then, as a configuration for more effectively avoiding the formation of the arch shape by the joint, the vibration device vibrates one or both of the upward inclined surfaces facing each other on the inner surface of the hopper. The aspect which is a thing can be mentioned.

  Furthermore, as an example of an aspect that contributes to more suitable dropping of the joint soil, an aspect in which the vibration device vibrates a plurality of portions of the hopper and vibrates the entire surface of the upward inclined surface can be exemplified.

  Further, as a configuration that has a simple configuration and can effectively promote the stable drop of the joint, the vibration device includes a motor that rotates the rotation shaft, and a portion other than the center of gravity is attached to the rotation shaft of the motor. And a vibrator that vibrates by rotation of the.

  Here, as a configuration of the joint spreader that can be used more simply and easily, there is a mode in which it is mounted on a self-propelled cart and operates using a drive source of the cart.

  In such a joint spreader, if the vibration device uses a battery mounted on the carriage as a drive source, the vibration device can be easily operated only when necessary.

  And as a concrete configuration for stably dropping the joints in the entire hopper by effectively operating the vibration device, the spraying device can move the joints from the front to the rear at the bottom of the hopper. The conveyor has a belt conveyor and a roll brush that disperses the joints transported by the belt conveyor, and the hopper is opposed to the forward and backward inclined surfaces facing diagonally upward in the joint storage part. It is possible to include an embodiment in which the roll brush is provided in the vicinity of the rearward upward inclined surface and the vibration device is provided on the frontward upward inclined surface.

  According to the present invention, it is possible to provide a joint spreader that can continuously and continuously spread the joint soil during operation.

The external view which concerns on one Embodiment of this invention. The other external view which concerns on the same embodiment. The typical structure explanatory view concerning the embodiment. FIG. 4 is a configuration explanatory diagram of a main part according to FIG. 3. Action | operation explanatory drawing which concerns on the same embodiment.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

  The joint spreader A according to the present embodiment is suitably used, for example, at a golf course, and is uniformly referred to as a joint S on the ground where the lawn is grown such as on a fairway or green. It is for spraying rubbing sand.

  This joint spreader A is provided integrally with a self-propelled cart D that is driven by a driver (not shown) in the present embodiment. However, it goes without saying that the joint spreader A may be detachably mounted on the carriage D.

  As shown in FIG. 1, the carriage D has a driver's seat DC and a driver's seat DC on a chassis DS supported by a rear wheel DR driven by an engine DE and a front wheel DF that can be operated by a steering wheel DH. This is a normal mode in which a joint spreader A is mounted on the rear side. And in this embodiment, while using the motive power of the engine DE which is the drive source which drives the said trolley D, the operation | movement which concerns on dispersion | distribution of the joint S in the joint spreader A is performed, and it accumulates with the motive power of the engine DE. Using the electric power of the battery DB (FIG. 4), the vibration device 3 described later can be arbitrarily operated. In the present embodiment, the description of the existing aspects essential to the carriage D, such as the brake and light aspects for driving the carriage D and the fuel tank for storing the fuel for driving the engine DE, is omitted. .

  Here, the joint soil spreader A according to the present embodiment includes a hopper 1 that houses the joint soil S, a spray device 2 that sprays the joint soil S discharged from the hopper 1 to the ground, and the spray device 2. And a vibration device 3 that vibrates the inner surface of the hopper 1 during operation and drops the soil S attached to the inner wall of the hopper 1. In the present embodiment, the specific configuration of the shutter device 4 provided immediately below the hopper 1, that is, the opening adjustment for adjusting the spread amount of the soil S per hour by adjusting the opening of the shutter. The illustration of the mechanism and the existing power transmission mechanism that transmits the power of the engine DE to the spraying device 2 is omitted for convenience of explanation, and in FIG. 2, FIG. 3, FIG. 3, and FIG. The part is shown broken away. Hereinafter, the configuration of the joint spreader A will be specifically described.

  As described above, the joint soil spreader A includes the hopper 1, the shutter device 4, the spray device 2, and the vibration device 3.

  The hopper 1 includes a joint soil accommodating portion 11 that accommodates the joint soil S to be spread on the lawn surface on the inner surface, and a joint soil discharge port 12 that discharges the joint soil S from below the joint soil accommodating portion 11 to the outside. Have The joint accommodating portion 11 is formed by bending or welding a steel plate so as to have a rectangular shape in plan view and an approximately inverted triangular shape in side view. And by setting it as the said shape, it is for accommodating joint soil S in the space provided between the front inclination board 13 and the rear inclination board 14, and between both the side boards 15. FIG. The joint S accommodated in the joint accommodating portion 11 always slides downward so as to slide down the front inclined surface 16 and the rear inclined surface 17 which are the upward inclined surfaces which are the inner surfaces of the front inclined plate 13 and the rear inclined plate 14. Guided. The joint discharge port 12 is an opening for guiding the joint S accommodated in the joint accommodating portion 11 and guided downward to the shutter device 4. And in this embodiment, the width direction both sides and center of the location which made the overhang shape located in the lower end front side of the front inclination board 13 in order to vibrate the whole area of the front inclination surface 16 among the upward inclination surfaces provided in the front and back A motor mounting portion 18 is provided. Further, a motor cover 19 for concealing the motor mounting portion 18 from the outside is further provided.

  The shutter device 4 is provided at a position indicated by a broken line in FIG. 1, and is an existing device provided so that the opening degree can be adjusted so as to adjust the amount of the soil S falling downward from the joint discharge port 12. It is. For example, the shutter device 4 is capable of adjusting an opening degree for determining a fall amount per hour of the joint S by adjusting an angle of a lever (not shown) provided around the joint accommodating portion 11. . Since the specific configuration and operation method of the shutter device 4 can use various existing modes, the description thereof is omitted.

  In the present embodiment, the spraying device 2 uses a so-called belt conveyor type mechanism. Specifically, a belt conveyor 21 that can move the joint S from the front to the rear at the bottom of the hopper 1, and a roll brush 22 that disperses the joint S falling from the rear end of the belt conveyor 21. Have. The belt conveyor 21 is used for moving the joint S, which passes through the shutter device 4 and falls by a required amount per unit time, to the rear. The belt conveyor 21 is driven by the power of the engine DE of the carriage D, and has a form in which a belt 25 is wound around the outer periphery of the front-side front roller 23 and the rear-side rear roller 24. The configuration of the power transmission mechanism for transmitting the power of the engine DE to the belt conveyor 21 is omitted because it is already existing. The roll brush 22 is, for example, a resin-made brush portion 26 that rotates while touching the tip of the spraying portion 20 that is the rear end of the conveying surface 28 that is the upper surface of the belt 25 that is conveyed from the front, and the brush portion 26. And a rotating shaft portion 27 which is a rotating shaft center. The rotary shaft portion 27 is configured so that the axial direction of the rotary shaft portion 27 is equal to that of the front roller 23 and the rear roller 24, so that the joint S on the transport surface 28 is obliquely lowered from the spray portion 20 positioned at the rear end of the chassis DS of the carriage D. It can be sprayed uniformly in the direction. The roll brush 22 is also connected to the engine DE via a power transmission mechanism (not shown) so as to be driven using the driving force of the engine DE of the carriage D. However, of course, the rotation of the roll brush 22 may be controlled independently of the belt conveyor 21. Further, the spraying device 2 may be driven by a drive source separate from the engine DE of the carriage D.

  Thus, the joint spreader A according to the present embodiment has the front inclined plate 13 to vibrate both the side plates 15 and the rear inclined plates 14 in the substantially entire area of the front inclined surface 16 of the hopper 1 and in the vicinity of the joint discharge port 12. A vibration device 3 is attached in the vicinity of the lower end of the.

  As shown schematically in FIGS. 2 to 5, particularly FIG. 4, the vibration device 3 includes a plurality of, ie, three motors 31 that are driven to rotate by the power of the battery DB (FIG. 4) mounted on the carriage D, and the motors. The vibrator 32 attached to the rotating shaft 34 of the motor 31, the mounting plate 33 for firmly mounting the motor 31 to the motor mounting portion 18, and the power supply to the motor 31 are attached near the motor cover 19. Power switch 35 and an operating switch 36 provided in the vicinity of the driver's seat DC. That is, only in the so-called “ON” state in which power supply to the motor 31 is permitted by the power switch 35, the motor 31 is turned on / off by operating the operation switch 36 provided, for example, near the side brake in the driver's seat DC. That is, it is possible to switch on / off. The vibrator 32 is made of, for example, a disk-shaped metal, and is provided with an eccentric hole 32a that is provided at a position different from the center and is attached to the rotation shaft 34 of the motor 31, and a main body that rotates around the eccentric hole 32a. 32b. That is, the vibration operation of the vibration device 3 is generated by the rotation of the vibrator 32 due to the rotation of the rotation shaft 34 of the motor 31. This vibration operation is transmitted through the motor 31 and the mounting plate 33, and can vibrate both the side plates 15 and the rear inclined surface 17 in the substantially entire area of the front inclined plate 13 and in the vicinity of the joint discharge port 12.

  Subsequently, the behavior of the soil S accommodated in the hopper 1 by the operation of the vibration device 3 will be described. Here, normally, when the well-dried joint soil S is accommodated in the hopper 1, the joint soil S in the hopper 1 does not operate the vibration device 3, and the joint soil S in the hopper 1 is an upward inclined surface 16. It is guided to the rear inclined surface 17 and sequentially guided to the joint outlet 12. However, the joint soil S may contain water depending on the storage condition of the joint soil S and the weather during operation of the joint spreader A. At this time, as shown schematically in FIG. 3, the joint S is fixed so as to be bridged between the front inclined surface 16 and the rear inclined surface 17 mainly in the lower part in the hopper 1. Unnecessary space SP may be formed above the joint discharge port 12. Then, even if the carriage D and the joint spreader A operate smoothly, the spread of the joint S is interrupted, and as a result, so-called uneven dispersion of the joint S is generated. Therefore, the vibration device 3 is operated in a situation that can cause such a situation.

  When the vibration device 3 is operated by operating the power switch 35 and the operation switch 36, that is, both are in the “ON” state, vibration occurs at least on substantially the entire front inclined surface 16 and on the front side of the side plate 15. As a result, as shown in FIG. 3, the joint soil S containing moisture is fixed so as to cross the inclined surfaces 16 and 17, and an unnecessary space SP is formed between the shutter device 4 and the structure shown in FIG. As described above, the fixed portion of the joint S is broken from the front inclined surface 16 side and the space SP is buried. As a result, even the soil S containing a large amount of moisture is continuously transported from the joint discharge port 12 through the shutter device 4 to the belt conveyor 21 and thus continuously at the rear end of the belt conveyor 21. By spraying with the roll brush 22 from the spraying part 20, the spraying of the stable soil S is implement | achieved continuously.

  Particularly in the present embodiment, the vibration device 3 is closest to the joint S, such as the vicinity of the lower end of the front inclined surface 16, and specifically, the distance from the rear inclined surface 17 facing from the vicinity of the lower end of the front inclined surface 16 is short. Where the earthen soil S is easily fixed, the strongest vibration occurs at the position because the vibration device 3 is assembled on the back side of the position. As a result, the adhesion of the joint soil S hardly occurs.

  Further, the position in the vicinity of the lower end of the front inclined plate 13 corresponds to a portion in the joint spreader A that has been referred to as “dead space”. In other words, the front side of the hopper 1 has an overhang shape so as to provide the front inclined surface 16 so that the joints can be easily dropped, but on the front side of the hopper 1 in order to effectively use the space on the chassis DS. A driver's seat DC on which the user sits must be provided. Therefore, an unnecessary gap that is difficult to use has been formed on the front side of the lower end of the hopper 1 so far. However, the present embodiment contributes to the effect of continuously spreading the joint S while effectively utilizing such “dead space”.

  By setting it as the above structures, the joint spreader A which concerns on this embodiment has a joint on the inner surface of the hopper 1 even when the joint S accommodated in the hopper 1 contains a lot of water. The problem of S sticking is effectively avoided. Thereby, the malfunction that the soil S cannot fall from the upper part of the hopper 1 is avoided effectively. As a result, the joint spreader A that can continuously and stably spread the working joint S is realized.

  Here, in many cases, the drop failure of the joint S as described above forms a general arch shape that bridges between the inner surfaces facing the joint S on the upper side of the hopper 1 bottom. Since the formation of the arch shape is often seen on the inner side surface, particularly on the upward inclined surface facing obliquely upward, in this embodiment, in order to more effectively promote the movement of the soil S by the vibration device 3, the vibration device 3, the front inclined surface 16 which is an upward inclined surface facing obliquely upward in the joint accommodating portion 11 is vibrated.

  Then, as a configuration for more effectively avoiding the formation of the arch shape by the joint S, the vibration device 3 vibrates both upward inclined surfaces of the pair of upward inclined surfaces facing each other on the inner surface of the hopper 1. For this purpose, it is provided in the vicinity of the lower end of the hopper 1 having an inverted triangular shape in side view. Accordingly, not only the front inclined surface 16 but also the entire vicinity of the joint discharge port 12 and a part of the side plate 15 can be vibrated, and the smooth drop of the joint S is promoted.

  Further, in this embodiment, the vibration device 3 has three motors 31, that is, a front inclination that is an upward inclined surface by providing a plurality of locations that vibrate by the motors 31 in order to contribute to a suitable fall of the soil S. The entire surface 16 is vibrated.

  In the present embodiment, the vibration device 3 includes a motor 31 that rotates the rotation shaft 34 and a vibrator 32 that is attached to a rotation shaft 34 of the motor 31 other than the center of gravity and vibrates by the rotation of the rotation shaft 34. By having the aspect which has, even if it is a simple structure, the stable fall of the joint S is promoted effectively. Specifically, when the vibration is generated by the rotation operation of the vibrator 32, the vibrator 32 generates vibration without colliding with anything else, so that unnecessary noise is generated when the vibration device 3 is operated. This does not unnecessarily damage the hopper 1 or other components.

  And in this embodiment, with respect to the joint spreader A which is mounted on the self-propelled cart D and operates using the drive source of the cart D, the vibration device using the battery DB mounted on the cart D as the drive source. By providing 3, the existing soil spreader A can easily improve the efficiency of spraying the soil S. Further, since the vibration device 3 is driven by the battery DB of the carriage D, the vibration device 3 can be easily operated only when necessary.

  In particular, in the present embodiment, the entire hopper 1 is provided by providing the vibration device 3 in the vicinity of the rear end portion of the front inclined plate 13 to vibrate the front inclined surface 16 with respect to the configuration of the so-called belt conveyor type soil spreader A. The structure which makes the soil S fall stably is realized. In addition, such a part is a part recognized as a so-called “dead space” in the conventional belt conveyor type, and by using this part effectively, unnecessary specification changes such as the chassis DS in the carriage D can be performed. The vibration device 3 is mounted without inviting.

  Although the embodiment of the present invention has been described above, the specific configuration of each unit is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention. For example, in the above embodiment, a belt conveyor type device has been described as the spraying device. The mode which can be spread over a wide range, and other existing various modes can be used. In addition, in the above-described embodiment, the vibration device is configured by a motor that is driven by electric power from a battery mounted on the carriage, but of course, the vibration device may be configured by using the driving force of the engine. In the above-described embodiment, the vibration device is configured by a motor that is rotationally driven by electric power. Of course, vibration generated by the vibration device is not limited to rotational drive. For example, the vibration device may be configured by using a so-called linear actuator that can perform a reciprocating operation by applying an alternating current. Further, the shape of the wheel traveling on the lawn in the carriage and the specific mode of the hopper and the shutter device are not limited to those of the above embodiment, and various modes including the existing one are applied. be able to.
