Description

Technical Field

[0001] The present invention relates to the technical field of seed collection equipment, and particularly relates to a forest seed collection device with a impurity removal function. Background Art

[0002] The collection of forest seeds is a key link in forestry production and ecological construction, and is of great significance for germplasm resource conservation, breeding of fine varieties, and restoration of forest ecosystems. Under natural conditions, the seeds of most forest tree species will fall off the mother tree due to gravity, wind, animal activities, etc. after maturity and scatter on the forest floor. Since most areas still use traditional methods to collect seeds at present, that is, relying on manual bending and picking or using simple tools to pick up on the ground, this operation method has many limitations and problems.

[0003] After forest seeds fall to the ground, they are easily mixed with sundries such as fallen leaves, dead branches, soil, and gravel, making it difficult to quickly identify and collect them centrally, resulting in a time-consuming and laborious collection process. Especially in areas with dense understory vegetation or complex terrain, manual operation is more difficult, further reducing work efficiency. Secondly, the long-term repetitive bending motion has a greater impact on the physical health of the collectors. Especially, the waist bears a large physiological load, which is extremely easy to cause occupational injuries such as muscle strain and lumbar disc herniation, not only affecting the physical health of the workers, but also increasing the labor cost and management difficulty. Summary of the Invention

[0004] The purpose of the present invention is to provide a forest seed collection device with a impurity removal function, which adopts a semi-automatic design, can collect seeds efficiently and quickly, and can also effectively remove impurities mixed in the seeds.

[0005] The above technical purpose of the present invention is achieved through the following technical solutions: A forest seed collection device with a impurity removal function, including a collection shell with an open lower end, one side of the collection shell is a feed inlet communicated with its lower end opening, a plurality of moving wheels are installed on both sides of the collection shell perpendicular to the feed inlet, a conveyor belt is movably arranged in the collection shell and extends from the feed inlet into its interior, driving rollers are rotatably connected to both ends of the conveyor belt in the collection shell, and the collection shell is equipped with a driving motor for driving the driving rollers to rotate; A plurality of brush strips are arranged on the outer side of the conveyor belt along its length direction, an aggregate trough is arranged in the collection shell away from the feed inlet, a guide plate connected to the edge of the aggregate trough is arranged below the conveyor belt in the collection shell, one side of the guide plate facing the feed inlet is inclined downward, and a plurality of strip-shaped sieve holes are arranged along its length direction on the side of the guide plate facing the feed inlet and opening backward; The end of the collecting shell away from the feeding port is rotatably connected to a hollow conveying handle, and the end of the collecting shell away from the feeding port is connected to a connecting hose connected to the lower end of the hollow conveying handle, and the connecting hose is connected to the collecting trough; It also includes a storage tank, the upper end of which is provided with a feed shell connected thereto, one end of the feed shell is connected to the upper end of the central control conveying handle and is connected thereto with a negative pressure hose, the upper end of the feed shell is provided with a negative pressure device connected thereto, and the upper end of the storage tank is provided with a battery for powering the drive motor and the negative pressure device.

[0006] By adopting the above technical solution, when collecting seeds, the staff pushes the collection shell back and forth on the ground with seeds through the hollow conveying handle, and the driving motor drives the conveyor belt to move, so that the brush strips on the conveyor belt brush the seeds on the ground into the guide plate in the collection shell. In the process of the seeds moving with the guide plate, small particles of impurities mixed in them fall through the strip sieve holes, and the seeds enter the collection trough along the guide plate; The operation of the negative pressure motor generates negative pressure in the negative pressure shell, and the generated negative pressure sucks the seeds in the collection trough upward through the hollow conveying handle, and enters the feed shell along the connecting hose, the hollow conveying handle, and the negative pressure hose. Since the seeds in the feed shell are heavier, they fall to the bottom of the storage tank.

[0007] The present invention is further configured as follows: the negative pressure device includes a negative pressure shell arranged at the upper end of the feed shell, the bottom of the negative pressure shell is connected to the upper end of the feed shell through a mesh layer plate, a negative pressure motor is installed at the upper end of the negative pressure shell, the power output shaft of the negative pressure motor is connected to a negative pressure fan in the negative pressure shell, and the side wall of the negative pressure shell is connected to the outside with an exhaust port.

[0008] The present invention is further configured as follows: a reflux channel is provided along the length of one side of the hollow conveying handle, an exhaust hose is connected between the upper end of the reflux channel and the exhaust port, the collecting shell is provided with a blowing strip on the upper side of one end of the feed port, a blowing port is provided obliquely downward on the side of the blowing strip away from the hollow conveying handle, and a reflux pipe is connected between the blowing strip and the lower end of the reflux channel.

[0009] The present invention is further configured such that one end of the conveyor belt away from the feed port is inclined upward.

[0010] The present invention is further configured as follows: waist fixing belts are connected to both sides of the material storage trough, and the free ends of the two waist fixing belts are connected by Velcro.

[0011] The present invention is further configured as follows: a discharge port is provided outwardly on the lower side of one side of the storage trough, and a sealing cover is threadedly connected to the discharge port.

[0012] A further setting of the present invention is that: a handle is inclined and arranged outward at the upper end of the hollow conveying handle.

[0013] In summary, the present invention has the following beneficial effects: First, during the process of the present invention using the collection shell, the brush strips on the conveyor belt automatically send the seeds onto the guide plate inside the collection shell. The small particle impurities are filtered through the strip-shaped sieve holes on the guide plate, and finally the seeds are attracted into the storage tank by negative pressure. It can achieve rapid seed collection without bending over, and can effectively remove the impurities mixed in the seeds, effectively improving the efficiency of seed collection, and also effectively reducing the damage to the health of the collectors caused by the collection work. Second, when sucking the seeds by negative pressure, the negative pressure generated can effectively clean the impurities attached to the surface of the seeds. The seed and dust impurities can be separated through the mesh layer plate. The airflow with dust impurities flows back to the feeding port position of the collection shell, which can effectively clean the fallen leaves around the seeds and prevent the airflow mixed with dust from blowing towards the collectors.
