Description

[Detailed explanation of the invention] (a) Industrial application field The present invention relates to a small and lightweight snow blower for removing snow accumulated on roofs.

(b) Conventional technology Although there have been small snow blowers for removing snow from roads and roads leading to houses, there is no machine that can remove snow that has accumulated on roofs, and such snow must be removed manually. I couldn't get it down without leaning over.

(c) Problems that the invention aims to solve Although the above-mentioned small snow blowers are small, they are too heavy to be mounted on the roof, and in order to remove snow from the roof, the slope of the roof must be adjusted. There are ways to increase the size of the roof, make the roof a material that can slide down, or melt it down, but these methods are economically burdensome. As a result, snow removal had to be done manually, and the work was extremely hard work.

(d) Means for solving the problem In view of the above points, the present invention has been developed as a compact snow blower having the following configuration.

In a snow blower that has an engine located in the center of the machine, a crawler-type traveling device that can move forward and backward, and a snow removal device, the snow removal device and the handle are centered around a fulcrum shaft that is perpendicular to the direction of travel and horizontally installed in the center of the machine. The snow removing device is configured so that it can be moved back and forth, and a chute is attached to the side of the snow removal frame of the snow removal device to discharge the snow in the lateral direction.

(e) Embodiments and operations The purpose of the present invention is as described above, and the structure and operations of the present invention will be explained based on the configuration of the embodiment shown in the attached drawings.

Figure 1 is a side view of the entire snow blower driven by an engine. Figure 2 is also a plan view. FIG. 3 is an overall side view of a snow blower driven by a motor as another embodiment. Figure 4 is also a plan view. FIG. 5 is a perspective view during operation.

The snow blower of the present invention has a small and lightweight engine, traveling device, etc., and is of a size and weight that can be easily handled by women, children, etc. The overall configuration will be explained with reference to FIGS. 1 and 2. 1 is a crawler, 2 is an engine, and the engine 2 is mounted on a body frame 3. The power from the engine 2 is changed in speed by a transmission case 4 and transmitted to a drive shaft 5 to drive the crawler 1. 13
is a lever that switches between forward and backward movement.

A support frame 9 and a chain case 10 are arranged on the sides of the crawler 5, and a snow removal device A is arranged at the tip thereof. The snow removal device A is a snow removal frame 1
2, an auger 11, a chute 17, a sled 19, etc., and a snow removal frame 12 is fixed to the tip of the support frame 9 and chain case 10. The support frame 9 and the base of the chain case 10 are pivotally supported on a rotation fulcrum shaft 7 protruding from the center of the body frame 3, so that the snow removal device A can be rotated back and forth. The chain case 10
A drive shaft for driving the auger 11 is installed in the center of the base, and the auger 11 is driven via a sprocket, chain, etc. Further, a handle 16 is provided protruding from the side of the rotation fulcrum shaft 7, and the handle 16 is also configured to be rotatable back and forth.

The auger 11 in the snow removal device A may be a spiral mechanism as long as it can be rotated to feed and discharge snow in one direction. A chute 17 is attached to the side opposite to the chain case 10, and the chute 17 is made of a flexible material, has a certain length, and can be extended by connecting. In addition, sleds 19 are attached to the upper and lower surfaces of the snow removal frame 12 to prevent it from digging downward. Further, the auger 11 can be reversed by switching the switching lever 14.

A clutch lever 20 is disposed on the handle 16, and is configured to be able to connect and disconnect the driving of the auger 11 and the crawler 1, and to rotate up and down around the handle 16 when switching back and forth. There is.

Other embodiments will be explained with reference to FIGS. 3 and 4.
A transmission case 4, a belt case 23, and a motor 22 are mounted on a body frame 3, and power is transmitted from the transmission case 4 to the crawler 1. Further, a drive case 24 is disposed between the transmission case 4 and the belt case 23, and is rotatable back and forth about a shaft 29. Therefore, it is possible to move forward or backward, and to switch the handle 16, just lift it upward and insert it into the pipes 26, 26. Furthermore, forward and backward movement and forward and reverse rotation of the auger can also be switched using an electromagnetic clutch.

A gearbox 25 is installed at the tip of the drive case 24.
A snow removal device A is fixedly installed through the drive case 24, and the snow removal device A is rotatable around the end of the drive case 24. That is, the direction of discharge from the chute 17 can be changed to either the left or right. Further, a switching lever 14 for switching the rotation of the auger 11 is provided on the side of the gear box 25. Furthermore, motor 22
Switching is required when moving forward or backward by rotating forward or backward. 27 is a button for stopping the motor 22.

With the above configuration, if the snow blower is raised to the roof by a bridge or the like as shown in Fig. 5, snow removal work can be performed laterally with the chute 17 facing downward.
Once it reaches the end, the handle and snow removal device can be reversed and the snow removal device can be moved in the opposite direction, as shown in FIGS. 1 and 3.

(F) Effects of the invention By configuring the invention as described above, the following effects can be obtained from the invention.

First, since the snow blower is small and lightweight and can be mounted on the roof, the labor involved in removing snow is greatly reduced.

Second, since the snow removal device and handle can be moved back and forth, it is possible to easily reverse and reverse work even in places where there is no room to turn, such as at four corners.

Thirdly, since it is configured to discharge in the lateral direction, it is possible to eliminate a discharge fan and the like, making it possible to make it smaller and lighter.
