Description

  The present invention relates to a depression angle-based warpage stop mechanism of an elevating frost-proof fan device.

  As is well known, installation / maintenance, etc. are easy in the prevention of frost and frost damage (frost prevention and / or anti-steaming etc.) in fields (farm) such as tea gardens (tea bowls), mulberry mushrooms, orchards, fruit vegetables and vegetables. As a method and apparatus (system) that can reduce the cost and price, there is a system (frost-proof fan method or frost-proof fan device) that uses air (warm air) of a reverse layer by a frost-proof fan. Among the defrosting fan devices, the elevating type defrosting fan device intended by the present invention is being useful. The reason for this is “1”. From the standpoints of modernization and aging of tea gardens, lack of manpower, etc., such as riding-type, rail-type, crawler-type large tea cutters, large-scale control machines, etc. , That there is no obstacle to the introduction of a large tea plantation management device (there is no obstacle because there is no conventional building pillar), “2” that the elevating defrost fan device can be securely accommodated in a small space of the teacup, “ 3 ”A mechanism that can effectively use warm air even in an elevating frost-proof fan (establishing a mechanism that can secure the length of the column) and / or an azimuth angle adjustment mechanism (azimuth swing device), a depression angle adjustment mechanism (horizontal swing device) The main contents are the development of the above and the like, and efficient defrosting.

  And in the elevating frost-proof fan device having these characteristics, it is becoming a situation where further improvement of the mechanism is desired. One example of this is to achieve automatic return and / or automation of the defrost fan, simplification of the depression angle adjustment mechanism, ease of operation, etc. in the elevating defrost fan device. Will be explained. In other words, a fastening tool fixed to the depression base mounting base enables the depression base to be moved on the depression base mounting base, and the fastening tool can be moved to a curved long groove (long slot) of the depression base. Adopt the configuration. In this configuration, as the column is erected, the depression base is maintained in its posture by the load of the defrost fan, while the fastener moves in the long groove in the forward direction (motor side of the defrost fan) (forward) The frost-proof fan reaches a predetermined depression angle through this posture maintenance and movement, and the depression base mounting base stands up together with the column. The end of this standing is in a use state, and the standing of the support and the depression angle of the frost-proof fan are ensured. On the other hand, in the process of sequentially tilting from the state where the column is erected, the depression base moves in a state where it is stopped at the depression position by the load of the defrost fan. Thereafter, the fan is further tilted, and the frost-proof fan refers to the ground in the teacup (GL or flat plate material, sliding plate material, slippery steel, slippery concrete, other slippery members, etc.) In the process of making contact with the ground, the defrosting fan is in contact with the ground and is regulated, and by this regulation, the fastener moves along the long groove in the backward direction (the depression base mounting side) (reverse movement). And). In the process in which the support column becomes substantially parallel to the ground through the backward movement, substantially all of the defrosting fan is simultaneously brought into contact with the ground and accommodated.

  Incidentally, the present applicant has submitted a defrosting fan with a horizontal swinging / swinging stop mechanism in the “defrosting method using a defrosting fan equipped with a swinging device” of Japanese Patent Laid-Open No. 10-26097. However, the object of the present invention is completely different from that of the present invention.

Accordingly, the rotation of the motor is transmitted to the first pivot 61 via the crank mechanism and / or the cam, and the relay box 60 is rotated in the azimuth direction (becomes azimuth swing).

  Further, an example of the horizontal swing device 7 shown in FIGS. 1-1 to 1-4, FIG. 2, and FIG. 3 is a motor (see FIG. (Not shown), a cam and / or crank mechanism (not shown), and a second pivot 70 provided in the relay box 60. The second pivot 70 protrudes out of the relay box 60. The second pivot 70 reciprocates as the rotation of the motor fixed to the relay box 60 is transmitted via the cam and / or crank mechanism. By the reciprocating movement of the second pivot 70, the depression angle adjusting device 8 and the defrosting fan 9 perform a horizontal swing (reciprocating) operation.

  An example of the depression angle adjusting device 8 shown in FIGS. 2 to 8 includes a substantially box-shaped depression base mounting base 80 provided on the second pivot 70, and an depression main shaft 81 and a fastening tool 82 ( It is configured by a depression-shaped base 83 having a substantially mountain shape in a plan view provided so as to be movable (movable) via a depression angle positioning shaft). In this example, the tightening tool 82 moves in the long grooves 830 and 830 (referred to as 830) provided in the depression base 83 to adjust the depression angle of the frost-proof fan 9. In this adjustment, the depression base 83 is configured to move reliably with the depression main shaft 81 as a fulcrum. Note that the depression angle main shaft 81 is configured so that the depression angle base 83 can move reliably and smoothly with the depression angle main shaft 81 as a fulcrum, as a positional relationship facing the fastening tool 82. Therefore, for example, in this example of the depression angle adjusting device 8, the fastening tool 82 tightly coupled to the depression angle base mounting base 80 is provided in the long groove 830 with flexibility (movably provided). As a result, as shown in FIGS. 1-1 to 1-4, when installed on the ground (the above-mentioned GL or flat plate material, sliding plate material, etc.), it is on the substantially extended line of the lifting pole 3 (FIG. 1-1). ) In the process of standing up sequentially (Figs. 1-2 to 1-4), the mechanism can be moved to a predetermined depression angle with the load of the frost-proof fan 9 (and the horizontal swing angle can be changed somewhat). To simplify the mechanism or ensure reliable accommodation and stability and securing of the depression angle. In FIG. 1-2, after the depression angle is secured by the load, the lift pole 3 rises at substantially the same depression angle (FIGS. 1-4). In the case of accommodation, although not shown, it is installed on the ground in a state where the above-mentioned depression angle is secured (see FIG. 1-2), and thereafter, as the lifting pole 3 approaches the ground, FIG. 1-1 Return to the original state of being regulated. In this example, the tightening tool 82 is provided in the long groove 830 of the depression base 83 using a tightening mechanism that uses a fastening means such as a nut and a fastening means such as a bolt provided on the depression base mounting base 80. And the attachment position of this fastener 82 can be changed in three places in the figure. However, these three locations are examples and are changed as necessary. The depression angle can be changed depending on the attachment position of the fastener 82. Further, the mounting position of the restricting plate (described later) is changed by changing the mounting position of the tightening tool 82 (changing the angle of the depression angle) so that the warping prevention (warping prevention function) can be surely achieved.

  The depression base 83 warping prevention mechanism, which is the point of the present invention, can move the restriction plate 831 to the depression base 83 via the third pivot 832 against the front plate 800 of the depression base mounting base 80. Provided. The lower end 831a of the restriction plate 831 is configured to be able to be locked to the lower end 800a of the front plate 800. That is, the lower end 831a of the restricting plate 831 is movable with a load and locked to the lower end 800a of the front plate 800 when the elevating pole 3 is erected (when the depression base 83 is set at the depression position). Thus, the depression angle base 83 is prevented from warping (preventing warping back). On the other hand, the lower end 831a of the restricting plate 831 is movable back by a load when the lifting pole 3 is inclined (in the inclined state in the process of housing), and is engaged with and disengaged from the lower end 800a of the front plate 800. It can be moved in the direction opposite to the 83 direction. The entire frost-proof fan device C including the frost-proof fan 9 can be accommodated in the tea plant space B ′ and accommodated in the tea plant B through this movement. In addition, the attachment position of this 3rd axis 832 can be changed in three places in the example of a figure. However, these three locations are examples and are changed as necessary. The attachment position of the third pivot 832 is attached to the attachment position of the above-described fastener 82.

  9 is the motor base 901 or the telescopic device 10 such as a cylinder movably supported on the depression base 83 and the depression base mounting base 80. The expansion device 10 is composed of an expansion / contraction rod 1000. Therefore, in this configuration, in a state where the depression base 83 is set at the depression angle position, a state in which the telescopic hook 1000 is extended is ensured. Warping of the frost-proof fan 9 is avoided through the extension device 10 and the extension rod 1000.

  In the figure, reference numeral 900 denotes a motor of the anti-frost fan 9. The motor 900 is attached to a motor base 901 provided on the upper surface of the depression base 83.

  Also, securing the depression angle of the depression angle base 83 (frost protection fan 9) by the load of the depression angle adjusting device 8 and housing it on the substantially extended line of the lifting pole 3 facilitate the understanding of the contents, cost and / or use. This is an example in consideration of the simplicity of the above. Therefore, other mechanisms that perform the same function can be employed. Further, the depression angle of the depression angle adjusting device 8 may be fixed at a predetermined angle (illustrated example), or may be changed by using a structure change, addition of parts, or the like.
