Description

  The present invention relates to a compost application machine and a compost application method for applying compost from a spout by rotation of a beater.

In general, a compost spreader is mounted on a truck or the like and spreads compost from the rear end of the truck. A loading platform that can be mounted on a truck or the like and is loaded with compost, and a beater that spreads compost from a spray port. A pair of spraying control plates that open and close the spraying port and a power gate that moves up and down so as to be able to open and close between the loading platform and the casing in which the beater is disposed.
Therefore, each of the pair of spraying control plates employed in the conventional compost spreader is configured to be rotatable around each column extending in the vertical direction, and the pair of spraying control plates rotate around each column. The spray port can be opened and closed by being moved.
However, when the compost is sprayed radially from the spout, if a pair of sprinkler control plates are rotated around each column and the spout is fully opened, each sprinkler control plate will be outward from both sides of the loading platform. It came out of the way and hindered driving.

On the other hand, the power gate adopted in the conventional compost spreader moves up and down between the loading platform on which the compost is loaded and the casing on which the beater is placed. Is performing an ascending or descending operation at the driver's seat, and when the power gate is raised or lowered at the driver's seat, the power gate is raised or lowered until the upper limit or lower limit switch is operated. And stops at the position where the upper or lower limit switch is activated.
In addition, when the compost loaded on the loading platform is sprayed from the spout, the power gate is stopped at a raised position until the space between the loading platform and the casing where the beater is disposed is fully opened.

However, if the power gate is stopped at a position where the space between the loading platform and the casing is fully opened, for example, when the compost is in a low-moisture and powdery state, the compost loaded on the loading platform will collapse during spraying. In such a case, a situation may occur in which the beater flows into the casing at once, and a large amount of compost may be sprayed from the spraying port, resulting in uneven dispersion of the compost.
Therefore, it is possible to control the drive of the electric cylinder to adjust the rising position of the power gate according to the nature of the compost, but from the driver's seat, the rising position of the power gate cannot be visually confirmed, Its position control is difficult.

In particular, Patent Document 1 discloses a conventional spray control plate employed in a compost spreader, which rotates from the inner side to the outer side in opposite directions from the spray port formed at the rear end of the cargo box towed by the tractor. In a compost spreader that spreads compost backward by a pair of disc-type beaters, it is attached to both left and right edges of the spout so as to be detachable and pivotable in a horizontal direction, and the tip is attached to the beater. A pair of inner restriction plates that extend rearward in the spraying direction along the rotation trajectory, and are attached to the outer side of the inner restriction plate so as to be detachable coaxially with the inner restriction plate and rotatable in the horizontal direction. Further, a compost spreader configured by a pair of outer regulating plates that regulate the spreading width of the compost that extends to the rear of the spreading direction from the tip of the inner regulating plate and is spread rearward by the beater is disclosed. ing
Japanese Utility Model Publication No. 06-81206

  However, the pair of inner and outer restriction plates of the compost spreader disclosed in Patent Document 1 is also attached to the support so that the angle can be adjusted in a horizontal direction so that the compost is removed from the spout. If it tries to scatter radially, a pair of inner side control board and an outer side control board will protrude outside from the both sides | surfaces of a packing box, and the problem mentioned above cannot be solved.

  The present invention has been made in view of such a point, and during spreading of compost, the spreading control plate has been improved and devised so as not to interfere with traveling, and furthermore, unevenness in the spreading amount caused by the properties of the compost can be eliminated. An object is to provide a compost spreader and a compost application method.

As a means for solving the above-mentioned problems, the present invention provides a compost spreader according to claim 1, wherein the compost is sprayed from a spout at the rear of the loading platform by rotation of a beater. Spreading control plates are installed on the columns that are installed upright on both sides of the spraying port so that they can rotate and slide up and down, and each spraying control plate is fixed at an arbitrary angle and height on each column. It is characterized by being able to.
Therefore, in the first aspect of the invention, when the compost is sprayed radially from the spraying port, the spraying port is fully opened by raising each spraying control plate to the maximum and fixing it to each column. Moreover, if each spraying control plate is rotated in the opening direction around a support column extending in the up-down direction and fixed at an arbitrary angle (within 90 °), the spraying width from the spraying port is changed. be able to.

The invention of the compost spreader according to claim 2 is the invention according to claim 1, wherein the compost spreader is capable of opening and closing between a loading platform on which compost is loaded and a casing in which the beater is disposed. An initial separation distance between an upper limit switch in the height direction of the power gate and a pressing member that presses the upper limit switch, which has a power gate that moves up and down and is close to each other as the power gate rises The upper limit height of the power gate can be adjusted by adjusting the setting.
Therefore, in the second aspect of the invention, the initial setting of the separation distance between the upper limit switch in the height direction of the power gate and the pressing member pressing the upper limit switch, which are close to each other as the power gate is raised, is adjusted. By doing so, since the upper limit height of the power gate can be adjusted to an arbitrary height, the opening amount between the loading platform and the casing by the power gate can be changed depending on the property of the compost.

The invention of the compost spraying method according to claim 3 is provided with a spray control plate that is rotatable and vertically slidable on the columns that are respectively provided on both sides of the compost spray port disposed behind the loading platform. In addition, each spray control plate is lifted to spread the spray control plate to open the spray port, and the spray control plate is rotated to open the spray port and control the spray width. By combining any one of the second posture for maintaining the rotation angle and the third posture for maintaining the spraying port in a closed state without operating the spraying control plate, The spray width and spray height are changed.
Therefore, in the invention of claim 3, the spreading width from the compost spraying port can be easily changed, particularly depending on the place where the compost is sprayed.

  According to the invention of the compost spreader according to claim 1 of the present invention, when the compost is sprayed radially from the spray port, the spray port is fully opened by raising each spray control plate to the maximum, Unlike the conventional case, the spreading control plate does not protrude from the side surface of the loading platform. Moreover, if each sprinkler control plate is rotated in the opening direction around the support column extending in the vertical direction and fixed at an arbitrary angle (within 90 °), each sprinkler control plate is attached to the side surface of the loading platform. It is also possible to change the spreading width from the spraying port without protruding outward.

  According to the invention of the compost spreader according to claim 2, the upper limit height of the power gate can be adjusted according to the nature of the compost, and the opening amount between the loading platform and the casing by the power gate can be changed. In particular, when compost is low in moisture and powder, the upper limit height of the power gate is set to a height that does not fully open between the loading platform and the casing where the beater is arranged, and the opening amount is If reduced, the compost loaded on the loading platform during spraying can be prevented from collapsing and flowing into the casing at once, and unevenness in the amount of compost spread caused by the properties of the compost can be eliminated.

  According to the compost application method of the present invention, the spread width of the compost from the spout can be changed depending on the place where the compost is sprayed. Can and is effective.

Accordingly, when compost is sprayed radially from the spraying port 4, the pair of spraying control plates 7a and 7b are fixed at a position where the spraying port 4 is fully opened. However, it does not hinder the running out of the side of the loading platform 3.
In addition, when changing the spreading width of the compost, the pair of spreading control plates 7a and 7b may be rotated together in the opening direction around the support column 25 at an arbitrary angle (within 90 °). If fixed, the pair of spraying control plates 7a and 7b can appropriately change the spraying width from the spraying port 4 without protruding outward from the side surface of the loading platform 3.

Further, in the compost spreader 1 according to the embodiment of the present invention, the limit switch bracket 52 to which the upper limit switch 49 of the power gate 8 is fixed is rotatable within the range of the long hole 53 around the other end. The limit switch bracket 52 whose position has been determined can be fixed to the support arm 51 by screwing the eye nut 55b to the screw rod 55a from the support arm 51 protruding from the long hole 53, and the upper limit switch 49, gate The initial setting of the separation distance from the electric cylinder 48 that is a pressing member that rotates to the upper limit switch 49 side and presses the upper limit switch 49 with the rise of 45 can be adjusted as appropriate. The upper limit height, that is, the amount of opening between the loading platform 3 and the casing 5 by the power gate 8 is made into the property of compost. To be adjusted appropriately I.
Thereby, especially when compost is low moisture and powdery, if the upper limit height of the power gate 8 is set to an appropriate height that does not fully open between the cargo bed 3 and the casing 5, It is possible to prevent compost loaded on the loading platform 3 from collapsing and flowing into the casing 5 at once, and to eliminate unevenness in the amount of compost applied due to the properties of the compost.

  In addition, although the compost spreader 1 which concerns on embodiment of this invention is mounted and used for the truck 2, it can also be employ | adopted as a compost spreader pulled by a tractor, and is a self-propelled compost spreader. Can also be adopted.
