Description

Technical Field

[0001] The utility model relates to the technical field of agricultural seed processing, in particular to an agricultural seed drying machine. Background Art

[0002] Agriculture is an industry that utilizes the growth and development patterns of plants and animals to obtain products through artificial cultivation. Agriculture belongs to the primary industry, and the science that studies agriculture is agronomy. Agricultural seeds refer to plant organs that can be directly used for sowing in agricultural production. When processing seeds, dryers are used to dry the seeds to ensure that the seeds reach the moisture standard for safe storage and increase the storage time of the seeds.

[0003] The prior art includes a utility model with publication number CN219531417U, which discloses an agricultural seed dryer. The patent adopts an oven body, and a pneumatic hot air blower is provided on the left side of the oven body. The air outlet of the pneumatic hot air blower is connected to the inner cavity of the oven body. The inner cavity of the oven body is provided with a screen, and the number of the screens is four. A sleeve rod is fixedly connected to the bottom of the inner cavity of the oven body and located below each of the screens. The inner cavity of the sleeve rod is provided with a movable rod. The utility model is provided with an oven body and a pneumatic hot air blower. The invention has the effect of drying the seeds. By setting the screen, the sleeve rod, the movable rod, the worm, the worm gear, the threaded rod, the transmission rod and the servo motor, the dried seeds can be unloaded, and the seeds in the inner cavity of the oven body can be discharged conveniently, which effectively reduces the labor intensity of the staff and improves the drying efficiency of the seeds. It solves the problem that after the seed drying operation is completed using the dryer, there is a lack of a seed unloading device, and the seeds need to be taken out manually, which increases the labor intensity of the staff and reduces the drying efficiency of the seeds.

[0004] In the process of processing seeds with the help of a dryer, there are existing dryers such as the above-mentioned ones, which use a jacking structure to push the screen when processing seeds, so as to facilitate the equipment to take out the seeds. Since the movable part of the jacking structure moves under the guidance of the sleeve rod, when the jacking part is fixedly connected to the screen, the moving trajectory of the screen is arc-shaped, and the jacking part guided by the sleeve rod is difficult to move according to the moving trajectory of the screen. In actual use, it will get stuck, resulting in the problem that the jacking part is difficult to lift the screen. Utility Model Content

[0005] The purpose of the utility model is to solve the problem in the prior art that when the jacking part is fixedly connected to the screen, the moving trajectory of the screen is arc-shaped, and the jacking part guided by the sleeve rod is difficult to move according to the moving trajectory of the screen, which may cause jamming during actual use, making it difficult for the jacking part to lift the screen. A seed dryer for agricultural use is proposed to solve the problem.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions: an agricultural seed dryer, comprising a base, a drying chamber and an auxiliary component, the drying chamber being mounted on the upper surface of the base, a ventilator being mounted on the upper surface of the drying chamber, the ventilator being communicated with the inner wall of the drying chamber, a chamber door being mounted on the inner wall of the drying chamber, a hot air blower being mounted on the side surface of the drying chamber, the hot air blower being communicated with the inner wall of the drying chamber, a bracket being mounted on the inner wall of the bracket, a placement net being rotatably connected to the inner wall of the bracket, a lifting mechanism being mounted on the inner wall of the base, a lifting end of the lifting mechanism being in contact with the lower surface of the placement net, and the auxiliary component being arranged on the inner wall of the base;

[0008] The auxiliary component also includes a connecting unit, which includes an assembly block, which is bolted to the surface of the connecting column, a positioning groove is provided on the side surface of the assembly block, the inner wall of the positioning groove is rotatably connected to a constraint shaft, the surface of the constraint shaft is fixedly connected to the assembly block, the upper surface of the assembly block is fixedly connected to a support plate, and the support plate is in contact with the lower surface of the placement net.

[0009] Preferably, the inner wall of the guide sleeve is fixedly connected to a limit strip, and a U-shaped groove is provided on the outer circumference of the connecting plate. The limit strip is slidably connected to the inner wall of the U-shaped groove. The connecting column and the compression spring can be connected through the connecting plate, so that the restraining force generated by the compression spring can constrain the position of the connecting column, thereby ensuring that the connecting column is always at a specified height in the absence of external force.

[0010] Preferably, there are two guide sleeves, which are symmetrically arranged with respect to the placement net. The movement direction of the connecting column can be guided by the cooperation between the guide sleeve and the connecting plate to ensure that the connecting column moves along the specified vertical direction.

[0011] Preferably, the connecting column passes through the upper surface of the retaining ring, and the retaining ring abuts against the upper surface of the connecting plate. The retaining ring installed above the guide sleeve can block the end of the guide sleeve to limit the moving distance of the connecting plate, while ensuring that the connecting plate is always in the guide sleeve.

[0012] Preferably, there are two assembly blocks, which are symmetrically arranged about the constraint axis. The position of the constraint axis can be supported by the assembly blocks installed on the surface of the connecting column to ensure that the position of the constraint axis is at the designed height.

[0013] Preferably, the assembly block abuts against the side surface of the assembly block, and the constraint shaft and the abutment plate can be connected through the assembly block, so that the abutment plate can rotate around the constraint shaft to determine the rotation axis of the abutment plate.

[0014] Preferably, the number of the limit bars is three, and the three limit bars are arranged in a circular array about the guide sleeve. The U-shaped groove matches the number of the limit bars. By installing the limit bars in the guide sleeve, the position of the connecting plate can be constrained with the cooperation of the U-shaped groove to reduce the chance of the connecting plate rotating during movement, thereby improving the stability of the connecting plate.

[0015] Compared with the prior art, the advantages and positive effects of the present invention are:

[0016] In the utility model, by setting an auxiliary component, when the seeds need to be dried, the seeds are placed on the placement net in the drying bin. After the placement is completed, the bin door is closed, the switch of the hot air blower is turned on, and the hot air blower is powered on to heat the drying bin. During the heating process, the drying bin will gradually dry the seeds. When the drying is completed, the bin door is opened and the lifting mechanism is turned on at the same time. The lifting mechanism works to lift the placement net, and the placement net rotates and tilts under the constraint of the bracket, and the seeds on its surface are poured out from the bin door; when the placement net rotates, the placement net pushes the push plate, and the push plate rotates under the guidance of the assembly block and the constraint shaft, and is always attached to the placement net. When the push plate rotates, the push plate cooperates with the assembly block and the constraint shaft to push the assembly block, and the assembly block pushes the connecting column, and the connecting column cooperates with the connecting plate to squeeze the compression spring. The compression spring The spring is squeezed and deformed. When the seeds on the placement net are completely cleaned and the lifting mechanism is reset, the placement net loses the pressure applied to the abutment plate. At the same time, the assembly block loses the pressure from the constraint shaft and the assembly block, and loses the pressure applied to the connecting column and the connecting plate. At the same time as the connecting plate loses pressure, the compression spring loses pressure and rebounds. The compression spring pushes the connecting plate during the rebound process, and the connecting plate lifts the connecting column. With the assistance of the compression spring and the connecting plate, the connecting column pushes the connecting unit to reset. The connecting unit pushes the placement net to reset while resetting. By setting auxiliary components, the lifting structure of the equipment can stably push the screen, thereby reducing the structural design of the existing equipment, which is prone to jamming during use, leading to equipment failure, and further improves the stability and rationality of the equipment structure.

[0027] Specifically, the inner wall of the guide sleeve 911 is fixedly connected to the limit strip 912, and the outer circumference of the connecting plate 913 is provided with a U-shaped groove 914. The limit strip 912 is slidably connected to the inner wall of the U-shaped groove 914. The connecting column 915 and the compression spring 916 can be connected through the connecting plate 913, so that the restraining force generated by the compression spring 916 can restrain the position of the connecting column 915, thereby ensuring that the connecting column 915 is always at a specified height in the absence of external force.

[0029] In this embodiment, the guide sleeve 911 cooperates with the connecting plate 913 to guide the moving direction of the connecting column 915 to ensure that the connecting column 915 moves along a specified vertical direction.

[0030] Specifically, the connecting column 915 passes through the upper surface of the retaining ring 917, and the retaining ring 917 abuts against the upper surface of the connecting plate 913.
