All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1 to 6, a fertilizer spreading apparatus provided by an embodiment of the present invention includes: a fertilizer throwing mechanism 1b, a tractor 1a, an induction unit 1d and a central controller 1 c.
The fertilizer throwing mechanism 1b comprises a fertilizer pushing mechanism 400 and a fertilizer throwing auger set 600 arranged behind the fertilizer pushing mechanism 400.
The tractor 1a is connected with the fertilizer throwing mechanism 1b to pull the fertilizer throwing mechanism 1b, the tractor 1a is provided with a PTO device 1a1, and the PTO device 1a1 and the fertilizer throwing auger set 600 are driven through a clutch.

As one embodiment, the pushing speed of the fertilizer board 402 and the traveling speed of the tractor required to achieve a certain amount of fertilizer per unit area may be recorded in advance, without limitation. When the fertilizing amount of a certain unit area is set, the fertilizing speed and the running speed of the tractor are matched with each other.
The fertilizing amount of the unit area can be calculated as follows and feedback adjustment is carried out, the fertilizer reduction amount can be obtained from the fertilizer weight difference value in a certain time period, the tractor travel can be obtained by multiplying the running speed of the tractor by the time period, and the fertilizer throwing area in the time period can be obtained by multiplying the tractor travel by the vehicle width, so that the fertilizer throwing amount in the unit area can be obtained by dividing the fertilizer reduction amount by the fertilizer throwing area. While the weight of the fertilizer can be obtained by the weighing sensor 7.
To better understand the technical solution of the present embodiment, the following examples are illustrated: under normal conditions, no matter whether the auger is started or normally runs, the set rotation speed ratio of the PTO rotation speed of the tractor 1a to the rotation speed of the fertilizer throwing auger set 600 is 4.5: 1, when throwing fertile screw feeder group 600 load too big, especially when throwing fertile screw feeder group 600 starts, easily appear the rotational speed ratio and be greater than 4.5: 1, it is described that the fertilizer spreading auger set 600 has an excessive load, and at this time, overload protection needs to be started, that is, the central controller 1c sends a signal to control and reduce the fertilizer spreading speed of the fertilizer spreading mechanism 400, and reduce the load of the fertilizer spreading auger set 600, so that the rotation speed ratio is normal. At the same time, the central controller 1c adjusts the traveling speed of the tractor 1a to match the current fertilizing speed based on the current fertilizing speed so that the fertilizing amount per unit area reaches the fertilizing amount set value.
The fertilizer throwing equipment can automatically judge and solve the problem that the fertilizer throwing auger set 600 is overloaded, and meanwhile, the fertilizing amount in unit area is adjusted by matching the corresponding fertilizer pushing speed and the corresponding running speed, so that the accuracy of fertilization is guaranteed, and the fertilizer throwing machine is favorable for application and popularization in an unmanned farm.

If the rotating speeds of the two screw feeders are not consistent, the gear box body between the two screw feeders is damaged. Under general conditions, the gear box body can not be damaged completely, and the left and right two sets of gear sets of the reduction box can be normally used. Therefore, the ratio of the PTO rotating speed to the rotating speed of one of the augers is a set rotating speed ratio, a first alarm signal is sent at the moment to prompt that the auger transmission has a fault, but the fault is small, the fertilization operation can be continuously completed, the rotating speed of the auger with a high reading is used as the rotating speed of the normal auger, and after fertilization is completed, the fertilizer throwing device needs to be moved to a maintenance workstation for parking and maintenance. If the first rotating speed ratio and the second rotating speed ratio are not set, the situation that the auger and the auger transmission system have large faults is indicated, and a second alarm signal is sent out at the moment to prompt that the fertilizer throwing operation is immediately finished.
According to the technical scheme, the different fault conditions of the auger are automatically distinguished by comparing and judging the speed ratio, so that the fault problem can be timely found, the complete fertilization operation is guaranteed as far as possible, and the maintenance of the fertilizer throwing equipment is more flexible.
