Description

Technical Field

[0001] The invention belongs to the technical field of agricultural planting and relates to a quantitative inoculation device for corn ears. Background Art

[0002] In the field of agriculture and plant breeding, corn is an important food crop, and its yield and quality are directly affected by the pollination process. The natural pollination of corn is through wind transmission, that is, the pollen produced by the male ear naturally falls to the stigma of the female ear with the help of wind to complete the fertilization process. This natural pollination method depends on environmental conditions, such as wind speed and weather conditions. When there is insufficient wind or rainy weather during pollination, it will lead to poor pollination, which will affect the development and yield of the fruit.

[0003] In order to overcome the influence of natural conditions on pollination, people began to use artificial pollination in agricultural production practice and in corn hybrid breeding to improve the success rate and uniformity of pollination. Artificial pollination can not only ensure the stable transmission of the genetic characteristics of excellent varieties, but also accurately control the pollination process under specific conditions (such as greenhouse cultivation or field trials), which is crucial for the research and breeding of new varieties.

[0004] However, traditional artificial pollination methods usually rely on manual operations, which are not only labor-intensive and inefficient, but more importantly, it is difficult to ensure the consistency and accuracy of the pollination amount each time. Especially when conducting large-scale farmland operations or sophisticated breeding experiments, how to achieve quantitative and uniform pollination has become a challenge. Although the existing equipment for corn ear inoculation and pollination can replace manpower to a certain extent, there are still many problems in practical applications, such as uneven spraying and serious pollen waste. These problems directly restrict the further improvement of corn yield and quality. Summary of the invention

[0005] The purpose of the present invention is to provide a corn ear quantitative inoculation device, which can accurately control the amount of pollen and ensure the uniformity of pollination, thereby helping to improve the quality of corn pollination and promote the development of the corn industry.

[0006] In order to solve the above technical problems, the present invention provides a quantitative inoculation device for corn ears, comprising a shell, a material storage barrel is arranged in the shell, an inoculation nozzle is arranged at the front end of the shell, an inoculation nozzle is arranged outwardly at one end of the inoculation nozzle away from the shell, the material storage barrel is open at one end facing the inoculation nozzle, a rotating groove is arranged in the shell at the open end of the material storage barrel, the rotating groove is rotatably connected to a rotating disk that is sealed and slidably connected to the open end of the material storage barrel, a plurality of material storage holes distributed in a circumference are opened on the edge of the rotating disk, a connecting channel for connecting the material storage holes and the inoculation nozzle is arranged in the inoculation nozzle, and the connecting channel can only be connected to one material storage hole at a time;

[0007] A hollow handle is obliquely provided at one end of the shell away from the inoculation nozzle, the hollow handle is open toward one side of the shell, an extrusion airbag is provided in the hollow handle, an end of the extrusion airbag close to the shell is connected to an air jet pipe extending to cooperate with the connecting channel, the free end of the air jet pipe is connected to the material storage hole and is sealingly and slidably connected to the turntable, an air outlet one-way valve is provided on the air jet pipe, and an end of the extrusion airbag away from the air jet pipe is connected to an air inlet one-way valve extending out of the hollow handle;

[0008] Both sides of the shell body away from the inoculation nozzle end are rotatably connected with connecting wheels, and the two connecting wheels are cooperatively connected with a trigger handle. The free end of the trigger handle is connected with an extrusion trigger capable of extruding the extrusion airbag. Both sides of the shell body are slidably connected with a sliding shaft that can slide along its length direction. Both sides of the shell body are provided with a sliding sleeve slidably connected to the corresponding sliding shaft. Each sliding shaft slides as the corresponding connection rotates. A driving head is provided at the end of each sliding shaft away from the trigger handle. Each sliding shaft is covered with a reset spring located between the corresponding driving head and the corresponding sliding sleeve. A transmission ring is provided on the outer periphery of the turntable. A circulating corrugated groove is opened on the outer periphery of the transmission ring. Each driving head is provided with a driving shaft slidably connected to the circulating corrugated groove. Each trough of the front and rear inner walls of the circulating corrugated groove is staggered with each other, and each crest of the front and rear inner walls of the circulating corrugated groove is staggered with each other, and the staggered directions of the crest and the trough are opposite, so that when the sliding shaft is extended and retracted back and forth, the transmission ring can be driven to rotate by the sliding of the driving shaft and the circulating corrugated groove.

[0009] By adopting the above technical scheme, pollen is first added into the storage barrel before use. When inoculating and pollinating the corn female ear, it is only necessary to pull the squeeze trigger to squeeze the squeeze air bag to spray the gas in the squeeze air bag to the storage hole through the jet pipe, so that the pollen in the storage hole passes through the connecting channel and then is sprayed from the inoculation nozzle to the corn female ear (it needs to be pressed several times for the first use to rotate the turntable until the storage hole with pollen faces the connecting channel). In the process of pulling the squeeze trigger, the connecting wheel is driven to rotate, and the turntable is driven to rotate, so that the next storage hole is rotated to face the connecting channel, which is convenient for the next press to spray and inoculate pollination.

[0010] The present invention is further configured such that one side of the storage barrel is connected to a feeding port extending out of the shell, and the feeding port is detachably connected to a sealing cover.

[0011] The present invention is further configured such that the material storage barrel is recessed inwardly to form a strip groove for the air injection pipe to pass through.

[0012] The present invention is further configured such that a pull wire connected to a corresponding connecting wheel is provided at one end of each sliding shaft away from the driving head.

[0013] The present invention is further configured such that a winding groove matching with a corresponding pull wire is provided inwardly on the outer side of each connecting rotating wheel.

[0014] The present invention is further configured such that each winding groove is C-shaped.

[0015] The present invention is further configured such that both sides of the shell are rotatably connected with traction wheels, each traction wheel is located between the corresponding sliding shaft and the corresponding connecting wheel, the outer periphery of each traction wheel is recessed inward to form a wire passing groove matching the corresponding pull wire, each pull wire is kept parallel to the corresponding sliding shaft and is wound into the corresponding traction wheel, and after passing through the corresponding traction wheel, it is wound along the tangent direction of the corresponding connecting wheel.

[0016] The present invention is further configured such that the air injection pipe is a hard pipe and is fixedly connected to the shell.

[0017] The present invention is further configured such that the cross section of the extrusion trigger is an arc shape matching the shape of the extrusion airbag.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] First, the present invention stores a fixed amount of pollen through the storage holes on the turntable, and uses air blowing to blow the pollen onto the corn ear to complete inoculation and pollination. The amount of inoculation each time is basically fixed, and uneven inoculation is not likely to occur. The pollen dosage can be accurately controlled to ensure the uniformity of pollination, which is helpful to improve the quality of corn pollination and promote the development of the corn industry.

[0020] Secondly, each time the present invention is used, inoculation and pollination can be completed by simply pulling the extrusion trigger, and each time the extrusion trigger is pulled, the turntable can be driven to rotate a corresponding angle through an ingenious transmission mechanism, so that the next storage hole filled with pollen can be rotated to face the connecting channel to prepare for the next spraying and inoculation. The operation is simple and easy to use, and the efficiency of corn inoculation and pollination can be effectively improved. BRIEF DESCRIPTION OF THE DRAWINGS
