[Detailed description of the invention] This invention relates to a device for compressing and molding feed such as Chigusa and straw.

In particular, this invention is equipped with a blade that supplies materials such as Chigusa to the space between the piston and the cylinder, and a space above the blade that communicates with the inside of the hopper. A feeding member is provided to circulate the material and supply it to the member that sends the material to the blade, making effective use of the material, enabling efficient material molding, and preventing the occurrence of material bridging within the hopper. This invention relates to feed forming equipment.

BACKGROUND ART A feed molding device called Hei-Cuba, which compresses feed such as grass and straw into a solid rod shape, is already known.

This type of feed forming apparatus compresses grass, straw, etc. into a suitable shape to facilitate transportation and to form it so that it is suitable as feed for livestock.

Conventional devices of this kind are generally large devices that use power of 30 to 50 horsepower, and the compression piston and the means for supplying the material to the piston are installed on the same surface, and the material is continuously supplied. is supplied and press-fitted into the cylinder every stroke of the piston to obtain a continuous rod-shaped pellet-shaped molded product.

Since such conventional devices are large and powerful,
There is no practical problem even if the load on the material feed, piston compression operation, and related mechanisms is large, but when miniaturizing this with small power, the material feed, piston Consideration must be given to each part and mechanism, such as the supply and insertion of the material between the cylinder and the cylinder, the relative position of the feeder and the piston, the compression timing, and the supply of the material by the hopper.

The present applicant has previously provided a feed molding device with the aim of downsizing and reducing the power of the feed molding device described above.

This feeds the material into the space between the piston and the cylinder, compresses and inserts the material fed by a compression blade into the space, and after compression and insertion, presses and compresses the material into the cylinder during the forward stroke of the piston.

When the compression blade inserts material into the space, the material thrown up by the rotation of the blade gets stuck between the blade and the upper wall, resulting in an unreasonable load on the blade and hindering the smooth operation of the blade. In addition to impeding the effective feed forming operation, an unreasonable load is placed on the drive mechanism such as the drive shaft, which is not desirable in terms of protecting the mechanism, and an unreasonable load is placed on the prime mover, which reduces the life of the entire fruiting device.
It also affects durability.

Furthermore, since the material is a fibrous material such as grass or straw, they become intertwined with each other inside the material supply hopper, causing bridging, which obstructs the smooth supply of the material.

The inventor came up with this invention in order to solve the above-mentioned problems mainly in the feed forming apparatus.

The purpose of this invention is to create a space that communicates with the inside of the hopper to prevent the material thrown up by the compression blade from clogging between the upper surfaces of this part when supplying material to the space between the piston and the cylinder. A feeding means is provided in this hopper, and the material splashed up into the space is sent in the direction of a feeding member that sends the material to the blade, so that the splashed material is circulated and supplied, and as a result of the above, the compression blade .

It prevents excessive loads on the drive shaft, drive mechanism, etc., ensures smooth and effective feed molding, enables effective molding of materials, and also prevents the occurrence of bridging due to entanglement of materials in the hopper. To provide a feed forming device capable of preventing the above problems and forming feed with high efficiency.

Further, the purpose of this invention is to provide a shaft parallel to the compression blade in the hopper as a feeding means for the sputtered material, and an arm curved on this shaft in the direction of the opening for feeding the material to the material feeding member. The blades are arranged radially and spaced apart in the axial direction, and the material thrown up by the rotation of the blades is sent toward the supply port of the hopper, and the material in the hopper is agitated to prevent the occurrence of bridging. To provide a feed molding device that does the following.

It is equipped with a wheel 9 and is driven by an internal combustion engine that drives a piston using a transmission mechanism such as a chain.

Two compression blades 10.1 are arranged at an angular interval of 180° on the circumference of a portion of the shaft 8 located on the reciprocating stroke of the piston 1.
0 is provided to protrude in the radial direction.

This blade 10.10 is twisted in the axial direction to distribute the load when the material is compressed, and a recess 11 is provided in the center of each outer end to avoid interference with the upper part of the piston 1.
11 is formed.

In the drawing, reference numeral 12 is a collar that rotates together with the blades 10 and 10 that prevent the material from becoming entangled during compression.

A screw feeder 13 is provided in front of the blades 10.10 of the drive shaft 8, the feeding end of the screw feeder 13 being offset to coincide with the opposite end of one of the blades.

A hopper 14 for supplying material is provided above the feeder case 7 including the compression blades 10, 10 and the screw feeder 13.

The upper part of the hopper 14 is tapered to one side to form an inclined guide surface 15 for easy loading of materials, and the lower end of the hopper 14 has an upper opening S of the feeder case 7.
A supply port 16 is formed which is compatible with 2.

This supply port 16 is provided above the screw feeder 13, and the compression blade 10.
10 to an open space S3 in the upper part of the hopper 10, so that the space S4 in the hopper 14 communicates with said space S3 of the compression blade 10.10.

The hopper 14 described above is placed on the feeder case 7 and is integrated with fastening means such as bolts and nuts.

The hopper 14 has the blade 10.
10. A support shaft 17 is installed parallel to and in the same direction as the shaft 8 of the screw feeder 13, and one end of this shaft 17 is connected to the hopper 1.
A sprocket wheel 18 is connected to the sprocket wheel 18 extending outside the side wall of the drive shaft 8, and is connected by a chain to an intermediate transmission sprocket wheel 19 provided at the shaft extending end of the drive shaft 8.

This support shaft 17 is connected to the lower vertical wall portion 14a of the hopper 14.
, 14b, and on the outer periphery of this support shaft 17, arm-shaped feed blades 20 are provided radially at equal angular intervals 9 In the illustrated example, three blades are provided at 120° intervals, and each feed blade 20... are provided at equal distances in the axial direction, one on the compression blade 10.10 and the other two on the screw feeder 13.

The feed blades 20 are formed to be curved from the base to the tip toward the feeder 13, which is the feeding direction, and are twisted to distribute the load in the radial direction.

Next, to explain its operation, materials such as Chigusa and straw put into the hopper 14 are supplied to the screw feeder 13 through the supply port 16 by the action of gravity, and the rotation of the screw feeder 13 causes a spiral feeding action between the compression blades 10 and 10. The material sent to the space S is supplied to the space S by the + rotation thereof, and the material supplied to the space S is pressed by one blade and compressed.

The material inserted into the space S during the forward stroke of the piston 1 is press-fitted into the molding cylinder 6, compressed, and molded as described above.

In the above, due to the rotary compression operation of the blade 10.10, the surrounding area and part of the material are thrown up, and the blade 10.10.
It accumulates in the space S3 above 10.

Since this space S3 communicates with the space S4 in the hopper 14, the material accumulated in this space S3 is stored in the hopper 14.
sent within.

In the hopper 14, the feed blade 20...
rotates, and by its feeding action, the material is sent toward the supply port 16 on the screw feeder 13 in the hopper 14,
The material thrown up into the empty space S3 by this feeding action is sent one by one, and as described above, the material is sent to the feeding blade 20...
By the operation, the material circulates through the space S3 above the blade 10 of the feeder case 7, the space S4 inside the hopper, the supply port 16, and the screw feeder 13.

Also, since the material is a fibrous material such as Chigusa or straw, Hopper 1
4 and let it fall by gravity, hopper 1
4 Material gets entangled in the center due to friction with the inner wall or lateral pressure, resulting in a so-called bridge, which obstructs the falling and supply of material and the smooth supply of material, which has a negative impact on molding efficiency. It also affects the specific gravity of the molded product.

In this case, since the feed blade 20 is rotating at the lower side of the hopper 14, the input material is agitated by the feed blade 20, so no bridging occurs. The falling of the material onto the screw feeder 13 is performed smoothly, and the supply of the material is not hindered and is performed smoothly.

As is clear from the above, according to this invention, a part of the material that is supplied and inserted between the piston and the cylinder by the compression blade, as well as the material around the compression blade, is splashed up by the rotation of the compression blade, and is thrown onto the blade. Even if the material accumulates, the space above the blade communicates with the inside of the hopper, so it is sent to this space, preventing load on the compression blade due to the accumulation of splashed material, and preventing the drive shaft, drive mechanism, prime mover, etc. It prevents excessive loads from being placed on the device, smoothes its operation, and protects the mechanism, thereby improving the durability and lifespan of the entire device.

In particular, the fed material is sent again to the material supply side of the hopper by the feeding blade and circulated, so that the space above the compression blade is always vacant and the material thrown up can be smoothly accommodated. In addition to improving the smoothness and protection of the mechanism, the material is circulated, so the material can be used effectively and without waste, improving molding efficiency.

In addition, the material in the hopper is stirred as the material splashed up by the feed blade in the hopper is fed, thereby preventing the occurrence of bridging due to entanglement of materials in the hopper, and ensuring that the material is fed smoothly and reliably to the feeder. In addition, it is easy to perform maintenance by simply installing a feed blade inside the hopper and communicating the hopper's supply port with the upper part of the compression blade, and does not require work such as removing splashed material. The top is also excellent.

In particular, according to the present invention, the member that sends the thrown up feed back to the supply side is formed as an arm-shaped blade extending radially from the shaft, and is not formed in a spiral shape. Effective agitation is now possible, and this agitation prevents entanglement of feed and the occurrence of bridging, thereby achieving smooth feeding of feed.
