Description

  The present invention has an obstacle to the use of tea garden management devices in view of the widespread use of tea garden management devices such as tea mowers and control machines (land and air control machines) from the viewpoint of mechanization and labor saving in tea gardens. The present invention relates to an anti-frost fan device having an automatic folding neck mechanism.

  As is well known, a tea garden management device has been adopted from the aspect of mechanization and labor saving of the tea garden. In connection with this, the harmful effect of the defrost fan apparatus using the present building pillar and overhead wire is pointed out. In other words, a pillar is erected in a farm such as a tea plantation or tea tree, and the overhead line, etc. stretched toward the building pillar becomes an obstacle when the tea garden management device is moved or operated, and plucking, pruning, and pest control Problems such as the inability to efficiently perform such operations and the fact that the building pillar and the anti-frost fan device on the building pillar are harmful on the landscape are regarded as problems.

  As part of solving the problem, the present applicant has proposed several low temperature type frost-proof fan devices for tea gardens. An example of this can be summarized as follows: a pillar (post) can be raised and lowered freely on the support part embedded in the tea garden, and the frost-proof fan is raised above the tea tree in the state where the pillar is raised to prevent frost. The frost-proof fan is laid sideways and the frost-proof fan is accommodated in the tea tree in a state where the frosted is contracted. However, in order to house the frost-proof fan in the tea tree using this up and down freestanding pillar, it is necessary to house the frost-proof fan guard in a state lower than the height of the tea tree. A configuration in which a pit is formed and the frost-proof fan is accommodated in an upright state using this pit, or a configuration in which the frost-proof fan is folded (declined) without forming a pit is conceivable. The housing using the pits has problems such as time-consuming work and the fact that the motor for driving the frost-proof fan is immersed in rainwater collected in the pits. Further, the configuration in which the frost-proof fan is folded and accommodated has problems such as the motor being immersed in rainwater collected on the ground when the folding direction is on the motor side for driving the frost-proof fan.

  References (1) and (2) can be cited as solutions for such problems, and an outline thereof will be described. Document (1) is a “frost-proof fan” disclosed in JP-A-10-113076. The outline is that a support part is provided at the tip of the telescopic pole, and the connecting member fixed to the blower main body is supported on the support part so that the swinging and raising / lowering can be adjusted, and the arm part of the supporting part and the connecting member A neck folding mechanism is provided. When the fan is accommodated, the pole is reduced, the orientation of the blower body is changed so that the front of the fan faces directly below, and the entire frost-proof fan is accommodated in the teacup. To be able to be accommodated in an unobtrusive position, or to ensure easy operation and / or to simplify the configuration, reduce costs, etc. by combining the neck folding mechanism and the elevation adjustment mechanism Features. Reference (2) is a “plant protection blower” disclosed in JP-A-10-323130. The outline is a plant protection blower equipped with a blower above the upper support, the lower support is embedded in the soil, and the upper support is accommodated in the lower support so as to be slidable in the vertical direction with a screw rod. The blower is mounted so that the upper column can be tilted up and down, and the front of the blower can be accommodated substantially horizontally on the ground. It does not interfere with the automatic tea-cutting machine during tea-cutting and is easy to install. The present invention is characterized by providing a plant protection blower, or because the blower is attached to the support arm via a support shaft so that the blower can be turned up and down.

  An example of the present invention will be described.

  Referring to the drawings, FIG. 1 is a side view for explaining a state in which a frost-proof fan is installed on a building pillar and frost-proof at a predetermined depression angle, and FIG. FIG. 3A is an overall view of FIG. 1, FIG. 3-2 is an overall view of a state where a part of a building pillar is inserted from the state of FIG. 1, and FIG. -3 is an overall view in which a part of the building pillar is inserted, and FIG. 3-4 is an overall view of FIG.

  Hereinafter, a preferred example of the present invention will be described. Reference numeral 1 denotes a telescopic building column, and in this example, a telescopic structure divided into three parts (an example). The expansion and contraction of the building pillar 1 is not limited because it has a mechanical structure, a cylinder mechanism, a wire structure, and the like. A substantially columnar building pole mounting body 2 is provided at the uppermost end 1 a on the bias side of the building pillar 1. A cylindrical body 3 is erected on the building pole mounting body 2, and the cylindrical body 3 is configured to be offset with respect to the center line of the building pillar 1. It is intended to ensure a balance with the center of gravity of a defrost fan or the like.

  Reference numeral 5 denotes a gantry provided with a mounting cylinder 50 to be fitted on the cylinder 3 of the building pole mounting body 2, and a main body 51 of the gantry 5 has a shape protruding toward the building pole, and the main body 51 The connection part 7 is provided in the front part (frost protection fan side). The connecting portion 7 is configured to turn by a drive mechanism built in the gantry 5. This is a so-called horizontal swinging operation. The connecting portion 7 is provided with a swing base 8, which swings simultaneously with the connecting portion 7. A substantially trapezoidal depression angle adjusting body 11 is movably supported in a side view through a pivot 10 provided at the tip of the swinging base 8, and a rear portion (anti-frost-proof fan 11) of the depression angle adjusting body 11 is movably supported. An arc-shaped kerf 1100 is provided in the side view, and an adjusting stop 12 screwed to the swing base 8 is inserted into the kerf 1100. When the adjustment stopper 12 is unscrewed, the depression adjusting body 11 is moved with the pivot 10 as a fulcrum (this movement is performed using the kerf 1100 as a guide), and the adjustment stopper 12 is screwed in after the movement. Thus, the depression angle adjusting body 11 is adjusted to a predetermined depression angle.

  A motor base 14 is movably provided at the upper end of the depression adjusting body 11 via a pivot 15. The depression adjusting body 11 is provided with an arcuate groove 1101 in a side view, and the other end 16b on the movable side of the gas spring 16 is inserted into the groove 1101. 16b is movable along the kerf 1101. Further, one end 16a of the gas spring 16 is pivotally supported by the lower end of the depression adjusting body 11, and the gas spring 16 moves in the process of contracting the gas spring 16 around the pivoted portion. Therefore, for example, as shown in FIGS. 3-1 to 3-4, a part of the building pillar 1 (as needed from the top building pillar 1) is lowered and the building pillar 1 and / or the frost-proof fan 30 is moved to the tea tree. In the process of housing in H, when this frost-proof fan 30 is pressed by the derivative G1 provided on the ground G, for example, in the process of FIGS. The gas spring 16 is contracted while the gas spring 16 is pressed by pressing the frost fan 30 with the derivative G1. In the process of contracting, the other end 16 b of the gas spring 16 escapes along the kerf 1101. This escape operation allows the motor base 14 to move. The motor base 14 can be moved by using the pivot 15 as an axis. That is, when the frost-proof fan 30 is accommodated in the tea tree H in the contracted (accommodated) state of the pillar 1, the contraction of the gas spring 16 and the escape of the other end 16 b of the gas spring 16 are used. By doing so, there is a feature that can be performed automatically and without the need for tools, and can be performed with extremely accurate, quiet and one-touch operation. In addition, when extending the building pillar 1 from the housed state and returning the frost-proof fan 30 to the depression position (frost-proof state or standing state), the building pillar 1 extends (the topmost). When the building pillar 1 expands) and the pressure on the anti-frost fan 30 is released, the pressure on the gas spring 16 is also released. As a result, the gas spring 16 is restored and sequentially extended, so that the motor base 14 is raised while the other end 16b moves from the lower end of the kerf 1101 toward the upper end. The frost-proof fan 30 returns to the depression position via the motor base 14 ascending, and the operation is substantially the reverse of the operation of housing the building pillar 1 and / or the frost-proof fan 30 described above. In addition, the return characteristics of the building pillar 1 and / or the frost-proof fan 30 are the same as those described above. The gas spring 16 is an example, and a cylinder or other mechanism that performs the same function is also possible.

  The frost-proof fan 30 is secured to an output shaft (not shown) of the motor 31 secured to the motor base 14 and includes a fan (blade) 3000 and a guard 3001.

  In addition, the defrosting effect etc. of the defrost fan 30 are based on a prior art example.

FIG. 1 is a side view illustrating a state in which a frost-proof fan is installed on a building pillar and frost-proof at a predetermined depression angle. FIG. 2 is a side view for explaining a housing state in which a frost-proof fan is shrunk together with a building column that is deflated at a predetermined angle toward the ground. 3-1 is an overall view of FIG. 3-2 is an overall view of a state where a part of the building pillar is inserted from the state of FIG.
