Description
Technical field
The present invention relates to a kind of novel threshing structure, the grain piece-rate system of vibrosieve structure and Automatic Control is specifically related to a kind of full-automatic grain piece-rate system that is used for the species test of individual plant high accuracy.
Background technology
It is indispensable processing section in early stage the agriculture species test research that grain is separated (threshing) from spike of rice; Especially in the high accuracy species test research, be a technical problem that is worth research and solves how automatic, efficient, high-precision grain is separated from spike of rice.At first, grain separate complete property can not only guarantee threshing effect preferably, and grain parameter measurements such as follow-up grain length, wide, the real grain number of grain, total grain number are had Practical significance clearly.Moreover the automation of grain separation realizes also realizing providing for whole species test process is full-automatic a kind of possibility.Full-automatic grain piece-rate system makes agriculture species test quick more and convenient, greatly reduces the error that artifact is brought, and has promoted agricultural research and Crop High-efficient species test.The research of accelerating full-automatic high precision grain piece-rate system has very big scientific research value and economic results in society.
Under this background prerequisite, existing both at home and abroad many researchs, and be applicable to the species test of individual plant high accuracy, and the automation domestic product that does not still have moulding of grain piece-rate system of having relatively high expectations to the threshing appearance.For a high accuracy, automation and measuring table attractive in appearance are provided to spike of rice, just must design and make a kind of grain piece-rate system that is applicable to the species test of individual plant high accuracy.Adopt stainless steel to add organic glass plate to constitute from this full-automatic grain piece-rate system design of the attractive in appearance and stable consideration of equipment is main, the Industry Control programmable logic controller (PLC) commonly used realization auto-control Design of programming is adopted in control.
Summary of the invention
Technical problem to be solved by this invention provides a kind of full automatic grain piece-rate system of individual plant high accuracy species test that is used for, and realization is put into spike of rice and promptly begun threshing and screening on the spike of rice pipeline automatically, improves threshing efficiency, reduces hand labor intensity.
For addressing the above problem; The present invention proposes a kind of full-automatic grain piece-rate system that is used for the species test of individual plant high accuracy; It is characterized in that, comprise real grain whereabouts baffle plate, wind direction guide plate, spike of rice pipeline, the spike of rice transition apparatus of spike of rice inlet, optoelectronic switch, sheller unit, vibration screening mechanism, wind device, the outlet of fringe bar, grain outlet, controller, band hairbrush; Optoelectronic switch is installed at said spike of rice pipeline place; Spike of rice pipeline upper end is right after the spike of rice inlet; Be right after the installation sheller unit behind the spike of rice inlet, sheller unit comprises full grain separating mechanism and flat grain separating mechanism, in the middle of full grain separating mechanism and the flat grain separating mechanism spike of rice transition apparatus is installed; Full grain separating mechanism below is equipped with the real grain whereabouts baffle plate of band hairbrush, and flat grain separating mechanism lower end is equipped with the wind direction guide plate; The sheller unit below is a vibration screening mechanism; The upper right side of vibration screening mechanism is the wind device, and left lower end is the outlet of fringe bar, and the vibration screening mechanism below is the grain outlet; Be written into the program that weaves in advance in the controller, controller is controlled whole threshing course automatically according to institute's reception optoelectronic switch induction input signal.
Further, said sheller unit comprises a toothrow shape cylinder (14) and the dentation belt conveyor (15) under it, and cylinder and belt conveyor are through the sawtooth coupling, and the dentation cylinder passes through adjustable bearing fixing up and down; Adjustable up and down bearing is connected and composed by nut (16), spring (17) and bearing (18) from top to bottom, and the pressure that adjusting nut can change middle springs moves up and down bearing centre, and then changes the pressure between dentation cylinder and pipeline belt; Wherein, Have dentation cylinder that elastic force fixes than the bearing of little spring relatively and under the dentation belt conveyor constitute a full grain separating mechanism, have dentation cylinder and flat separating mechanism of the formation of dentation belt conveyor down thereof that the bearing of the relatively large spring of elastic force fix.Spike of rice at first gets into full grain separating mechanism; Most of full grain is taken off the back and is fallen on the vibration screening device by the real grain whereabouts baffle plate (10) of band hairbrush; The remaining spike of rice that does not purify runs to flat grain separating mechanism through spike of rice transition apparatus (13) to be separated, and finally separated grain and fringe bar are fallen on the vibration screening device by flat grain separating mechanism end.To different crops, different according to connection power between its grain and the grain ear, regulate corresponding spring pressure and can reach optimal threshing effect.
Further, the panel of said vibration screening mechanism is the fish scale sieve plate; It below the fish scale sieve plate grain gathering unit of a skewed slot type; Gathering unit is installed a pole (19) down; It under the pole roller (20); The roller below connects the tumbler (21) of a surperficial dipping and heaving; Tumbler is connected on the motor through bearing (22), and tumbler rotated when motor rotated, thereby made whole vibration screening mechanism (5) up-down vibration.
Control flow of the present invention is: behind the starting device; When optoelectronic switch detected spike of rice pipeline porch spike of rice is arranged, optoelectronic switch was issued controller with signal, and controller starts threshing part and vibration screening mechanism; Threshing and screening finish after a period of time; Controller starts the wind device fringe bar on the sieve plate and impurity is blown out from the outlet of fringe bar, and exports the grain that obtains separating from grain, and individual plant threshing so far finishes.The threshing course controller does not respond the input signal of optoelectronic switch, and threshing back controller fully recovers the response to the optoelectronic switch input signal automatically, can carry out next strain experiment, constantly moves in circles successively.
It is effective that the present invention has threshing, and adaptivity is good, is prone to regulate the advantage of control.In grain species test work, adopt the present invention, improved the species test precision greatly, reduce the labour intensity and the human error of workman's threshing.And the present invention's installation, easy to maintenance, the operation troubles rate is low.
