Description

Movable multifunction honey extractor

The present invention relates to a mobile-type harvesting apparatus, and more particularly, while driving and moving along a movement path in which beehives are placed, honey is collected from each beehive's milling to obtain honey in a drum, and then the obtained drum is transported in a transport vehicle. It relates to a mobile sieving device to be loaded into a loading box.

In general, the milling machine (採蜜機) puts the consumption (巢脾, = honeycomb), which is in large number in the rod shape (蜂箱, = beehive) during beekeeping, into the inside of the drum and rotates it for centrifugal separation. It is a device that separates the honey stored for consumption by

The honey collected by the bees is filled with consumption put in the hive, and after a sufficient amount of honey for consumption is filled, the consumption is taken out, put into a sieve using centrifugal force, and rotated, thereby extracting honey from consumption by centrifugal force. become dense.

This mining operation is performed in a place away from the place where the hive is placed. For example, after loading the hive and moving it to the place where the excavator is installed, the consumption is taken out, or the consumption is taken out from the place where the hive is placed and loaded on a cart for transportation of consumption. After moving to the place where the sieving machine is installed, remove the membrane blocking the entrance to the honeycomb of consumption, put it in the sieve, and rotate it with a strong rotational force to obtain honey filled in the sieve.

Since the place where the beehive is placed and the place where the milling machine is placed are different, the beehive or consumption is moved to the milling machine, and the beehive or consumption after the milling operation is moved to the place where the beehive is placed and installed or filled in the beehive. As a result, it requires a lot of manpower while carrying out a difficult task as much as transporting consumption.

And, due to the weight of the milling machine, it takes a lot of force to transport the milling machine, and also, it is difficult to transport the honey collected by the milling operation from the place where the milling machine is placed to the place where the honey is stored because the honey collected by the milling operation weighs a lot. If the drums are collected in a drum, the drum must be loaded in the loading box of a transport vehicle such as a truck, but it is very difficult to lift the drum to the loading box position.

In order to solve the inconvenience of this fixed sieving machine, as described in Republic of Korea Utility Model No. 220395 (announced on April 16, 2001) or Registered Utility Model No. 369753 (published on December 9, 2004) A transfer wheel is installed on the side or a transfer means is installed on one side of the lower side to transfer the sieve to a desired location, or as described in Korean Patent Publication No. 2007 No. 115445 (published on December 6, 2007). A transport device for a chamfer that can be loaded and transported has been developed.

These conveying devices for milling machine have the advantage of ensuring the convenience according to the transport and loading of the drum along with the convenience according to the milling, but the following problems are pointed out.

First, the transport devices for the milling machine are all mounted on a single car body, the lifter loading unit for lifting the milling machine, the storage tank, the discharge pump, and the drum to raise and load it in the loading box of the truck. It is difficult to secure driving convenience because the car body of the vehicle must be moved along a narrow sieving road, and the large body must be moved along a narrow or highly curved transport path when moving and loading the compacted drum into the loading box of the truck. ,

Second, in the process of transporting the drum along the conveying path, since it is difficult to simultaneously perform the mining process, the productivity according to the mining decreases,

Third, since the drum in which the harvested honey is stored is forcibly loaded into the loading box of the truck, it has a limitation that requires a lot of labor.
