Description

[0001] ELECTRONIC CONTROLLED AIR PLANTER

[0002] Technical Field

[0003] The invention relates to a seed spreading module of the electric air planter used for planting seeds and spreading granular and liquid fertilizer on agricultural lands.

[0004] The State of Art

[0005] The process performed after tillage in agricultural production is planting. The vegetative production process begins with planting. This process continues through various stages until a new plant and eventually a new seed is formed. Planting is the placement of the seed or plant part that will form the main plant, by the requirements of the plant, in the prepared seedbed for vegetative production and covering it with soil or planting it. Planting machines should be able to plant all kinds of small and large-grained seeds without damaging them or losing their germination ability, be able to plant the desired amount of seed and fertilizer to the unit area in the desired row spaces, be able to plant the desired amount of seed fertilizer to the unit area at the desired inter-row distances and be able to bury the seed-fertilizer in the soil at the desired depth. The purpose of planting is to start the vegetative production process. This process continues through various stages until a new plant and eventually a new seed is formed.

[0006] Machines that can bury the seeds into the soil at the desired interrow and interrow distance and depth are called planting machines (planter). There are many types depending on the connection type to the tractor, the purpose of use, and the features of the machine. Features to be wanted for in planters are that they have the opportunity to adjust depth, fertilizer, and seed norm (amount).

[0007] Today, different types of discs with specialized hole numbers and hole diameters for each seed type are used in the seed spreading module of mechanical or electric air planters. Since these discs are different, the discs in all planting units are changed in each different type of seed. This process causes additional loss of time and additional labor. There is no active air vacuum / pressure control in the seed spreading module of existing mechanical or electric air planters. As a result of this, different vacuum / pressure values may occur in each seed spreading module of the planting unit. Seed malfunction adjustment of each unit may need to be made specific to that unit due to different pressure values. For various reasons, vacuum / pressure losses occurring in the seed spreading module of the units cannot be detected and the seed planting quality decreases during the planting operation, and this cannot be corrected by instantly and actively controlling it for each unit separately.

[0008] Today, various studies have been carried out and new structures have been developed to plant different seed types with existing planting machines. One of these studies is the invention that is the subject of the patent application numbered TR2016 / 19519 and titled "Seed distribution element for sensitive seed planting machines, seed planting machine comprising said element". It is a seed spreading element comprising a planting disc rotated by a motor-driven transmission shaft; a housing having a fixed section on which the shaft is supported and a section movable relative to and closing against the fixed section; a seed collection chamber in the fixed section; a pneumatic suction chamber in the movable section; a planting disk placed between two sections and having opposing surfaces limiting the chambers, and provided with a ring of separative holes extending between the opposing surfaces; a means producing a pressure difference between opposing surfaces in the region of a circular section of the ring that belongs to holes and comprising a pneumatic suction chamber, and; a seal on the movable section that can slide in contact with the facing surface of the disc when the two sections close against each other; a thrust bearing element of the seed disc that is rotatable supported in the movable section to withstand the axial load generated by the disc in the seal.

[0009] Another study is the invention that is the subject of the patent application numbered TR2015 / 00433 and titled "Seed distribution element for sensitive seed planting machines, seed planting machine comprising said element". It is a seed spreading element comprising a planting disc rotated by a motor-driven transmission shaft, a housing having a fixed section on which the shaft is supported and a section movable relative to and closing against the fixed section, a seed collection chamber in the fixed section, a pneumatic suction chamber in the movable section, a planting disk placed between two sections and having opposing surfaces limiting the chambers, and provided with a ring of separative holes extending between the opposing surfaces, a means producing a pressure difference between opposing surfaces in the region of a circular section of the ring that belongs to holes and comprising a pneumatic suction chamber and a seal on the movable section that can slide in contact with the facing surface of the disc when the two sections close against each other, a thrust bearing element of the seed disc that is rotatable supported in the movable section to withstand the axial load generated by the disc in the seal.

[0010] Another study is the invention that is the subject of the patent application numbered TR2020 / 03403 and titled “A distribution box for a single seed planting machine with mixing wings and a seed planting machine using such a distribution box.” The present invention relates to a distribution box for a single seed planting machine, comprising a perforated disc mounted rotatable around an axis of rotation to select seeds assisted by airflow, said disk separates the seeds from the airflow and has holes opening at regular intervals around at least two concentric circles located near the edge of the disc, there are holes in these two circles, connected by an angular projection, and these holes are of a suitable size for planting seeds. The box provides angled protruding mixing wings at regular intervals around said disk and relative to said pores, and said mixing wings extend between two circles. The present invention also relates to a single seed the planting machine using a distribution box according to the invention.

[0011] In conclusion, the existence of the need for an active vacuum / pressure-controlled seed spreading module that eliminates the disadvantages of the present can be used in planting more than one seed type with a single disc, and the inadequacy of existing solutions has made it necessary to make a development in the relevant technical field.

[0012] Brief Description of the Invention

[0013] The present invention relates to a seed spreading module of the electric air planter that meets the above-mentioned requirements, eliminates all disadvantages, and brings some additional advantages, used for seed planting and granule and liquid fertilizer application on agricultural lands.

[0014] The aim of the invention, based on the state of the art, is to enable the use of a single disc for more than one seed type, thus enabling the adjustment to switch to different seed types simply and quickly, without the need to change discs for planting different types of seeds using the opening and closing of holes of different characteristics placed on a single disc with a membrane, membrane protector and selective wheel.

[0015] The invention aims to instantly measure the module's internal vacuum / pressure using the vacuum / pressure sensor located on each seed spreading module.

[0016] Another aim of the invention is that the vacuum / pressure instantaneous values on the electronic system are controlled by actively increasing or decreasing the vacuum / pressure value with the seed spreading module and / or the electronic air control valve placed on the vacuum / pressure line so that it remains constant at the targeted vacuum / pressure value using the instant measurement of module internal vacuum / pressure. Another aim of the invention is to ensure that the vacuum / pressure is constant and at the desired value in each unit and to eliminate the need for different malfunction settings for each unit seedspreading module.

[0017] Another aim of the invention is to ensure that the planting quality is maintained during the planting operation by measuring the instant vacuum / pressure value and fixing the vacuum / pressure at the desired value with the electronic air control valve.

[0039] Detailed Description of the Invention

[0040] In this detailed description, the seed spreading module (100) of the electric air planter (200) of the invention, which is used for seed planting and granular and liquid fertilizer spreading on agricultural lands is described only as an example of a better understanding of the subject and in a way that does not form any limiting effect.

[0041] The electric air planter (200) shown in Figure 1 places and plants the seeds in the soil at the desired spacing for the production of products and buries them at a certain desired depth. Said planter (200) comprises a multiple seed disc (103) containing holes with different features placed on it, a seed spreading module (100) developed to enable the use of a single disc for more than one seed type by opening and closing the holes with a selective membrane (104), a selective membrane protector (105) and a selective wheel group (107). In the electric air planter seed spreading module (100), on the main body (101), multiple seed discs (103), the selective membrane (104), the selective membrane protector (105), a disc main body (106), the selective wheel group (107), a seed spreading counting sensor (112) are placed with various bedding and fixing devices. On the side body (102), a vacuum seal (108), a hole plugging / cleaning group (109), a disc drive motor (110), a disc cycle encoder (111), a vacuum / pressure sensor (113), an electronic air valve (114) are placed with various fixing devices.

[0042] The functional parts of said seed spreading module (100), shown in Figure 2, are placed or fixed on the main body (101) and side body (102). The seed spreading counting sensor (112) is located at the bottom of said main body (101), where the seed spreading is read and the seed spreading time and whether the seeds are spread insufficiently or excessively are checked. In said seed spreading module (100), there is a multiple seed disc (103) on which multiple holes of different diameters and / or shapes required for different types of seeds are positioned. Among the different types of seed holes in the said multiple seed disc (103), there is the selective membrane (104) that opens the required hole to vacuum or pressure with its flexible structure and closes the others. Said selective membrane (104) is carried on the selective membrane protector (105) and is protected from irregular movements of the seed. The multiple seed disc (103), the selective membrane (104), and the selective membrane protector (105) are positioned on the disc main body (106), which receives the rotation movement from the disc drive motor (110). Said selective wheel group (107) provides the transition between holes of different diameters and / or features outside the seed spreading module (100), with its pressing, releasing, and rotating features. The sealing of the vacuum / pressure required for fixing the seeds to the holes in the multiple seed disc (103) is provided by the vacuum seal (108) using its flexible structure. The hole plugging / cleaning group (109) is positioned behind said multiple seed disc (103) to ensure the free fall of the seeds by resetting the vacuum pressure and cleaning the holes from waste. Said multiple seed disc (103) is rotated by the disc drive motor (110), which is an electric motor. The rotation cycle provided by the disk drive motor (110) of the multiple seed disk (103) is read by the disk cycle encoder (111). A vacuum / pressure sensor (113) is connected to the side body (102) shown in Figure 3 to detect the vacuum / pressure value formed inside the seed spreading module (100). An electronic air valve (114) is positioned to reduce, open, or bypass the vacuum / pressure value formed in the seed spreading module (100) and keep it at the desired value.

[0043] The seed spreading module (100) of the electric air planter (200) works to pass the planted seeds in front of the seed spreading counting sensor (112) in a stable manner and at the desired timing. The data of this study is controlled by the system software via the system's electronic motherboard. The rotational movement drive of the multiple seed discs(103), which is required based on the data coming through the system, is provided by the disc drive motor (110). The control that says multiple seed disc (103) rotates at the desired cycle is performed by the disc cycle encoder (111). The seeds fixed to the holes of the multiple seed disc (103) with the vacuum / pressure formed in the seed spreading module (100) are brought in front of the seed spreading counting sensor (112) by the rotation movement of the multiple seed disc (103). With the hole plugging / cleaning group (109) positioned at this exact alignment, the vacuum / pressure that fixes the seeds on the holes of the multiple seed disc (103) is reset and their free fall is ensured. The fallen seeds are checked for quantity and stable spreading by the seed spreading counting sensor (112). Seed spreading number and timing data are fed back to the system's electronic motherboard.

[0044] The seed spreading module (100) comprises a multiple seed disc (103) structure to enable different types of seed planting without the need for disc replacement. This structure comprises more than one type of hole specific to different types of seeds. These holes are placed on the multiple seed disc (103). There is a selective membrane (104), a selective membrane protector (105), and a disc main body (106) placed and bedded in a row on said multiple seed disc (103). These structures can move angularly on each other and then be fixed using the selective wheel group (107). With this movement, the desired type of hole is opened and other types of holes are closed. In this way, there is no need to change discs for more than one type of seed. Vacuum / pressure is formed in the seed spreading module (100) to fix the seeds in the holes. This vacuum / pressure is protected within the seed-spreading module (100) by the vacuum seal (108). The vacuum / pressure in said seed spreading module (100) is measured instantly by the vacuum / pressure sensor (113) and the data is transferred to the system's electronic motherboard.

[0045] Based on this data, the electronic air valve (114) reduces, opens, or bypasses the vacuum / pressure to keep the desired vacuum / pressure consistently constant. In this way, it is ensured that the vacuum / pressure is at the desired value in each unit. In this way, the need for individual malfunction adjustments for each unit is avoided.
