Description

Technical Field

[0001] This invention relates to the field of barley sowing technology, and more specifically, to a barley sowing device for barley breeding experiments that can sow barley evenly. Background Technology

[0002] Barley is an annual herbaceous plant belonging to the Poaceae family and the Hordeum genus. Its culms are stout, smooth, hairless, erect, and can reach up to 100 cm in height. The leaf sheaths are loosely clasping the stem, mostly hairless or with soft hairs at the base; each leaf has two lanceolate auricles on each side; the ligule is membranous; the leaf blades are flat; the inflorescence is a spike-like inflorescence with dense spikelets, all of which are sessile; the glumes are linear-lanceolate, covered with short soft hairs; the palea and lemma are nearly equal in length; the caryopsis adheres to the lemma when ripe and does not detach. Barley is highly adaptable, tolerant of poor soil, salt, and drought, and is widely cultivated in most parts of my country, mainly for brewing and providing high-quality feed for livestock and aquaculture.

[0003] In the process of breeding new barley varieties (lines), strict requirements are placed on the plant spacing and row spacing of the new barley varieties (lines) planted in the seed selection nursery of the experimental field. It is essential to ensure that the plant spacing and row spacing of all participating barley varieties (lines) are consistent to guarantee the accuracy of the final selected new varieties (lines). Currently, sowing in the barley breeding experimental field seed selection nursery relies on manual furrowing and seed sowing. During sowing, it is difficult for researchers to precisely control the number of barley seeds sown and the distance between each seed, which can easily lead to mis-sowing, missed sowing, and double sowing. This results in uneven sowing of the participating barley varieties (lines), affecting barley growth and consequently impacting the researchers' final judgment on the growth of the barley varieties (lines) throughout their entire growth period. Consequently, some originally high-quality, high-yielding barley varieties (lines) are not selected due to poor growth caused by improper manual sowing operations in the seed selection nursery, resulting in losses in barley variety breeding efforts. Therefore, we propose a barley sowing device for barley breeding experiments that enables uniform sowing. Summary of the Invention

[0004] The purpose of this invention is to provide a barley sowing device for barley breeding experiments that can sow barley evenly, so as to solve the problems mentioned in the background art.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] 1.

[0014] 2. In the barley seeding device used in this barley breeding experiment, the main valve, the branch valves, and the first infrared counter ensure that the number of seeds falling to the ground by each seeding tube is constant, thus avoiding missed sowing or double sowing. At the same time, the equal distance between each seeding tube also ensures that the distance between each seed is the same, making the barley sowing more uniform. Attached Figure Description

Detailed Implementation

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Please see Figure 1 - Figure 8As shown, this embodiment provides a barley sowing device for uniform sowing in barley breeding experiments, including a placement plate 100. A seed box 101 is placed on the upper surface of the placement plate 100. A downward-sloping pipe 102 is connected to the lower surface of the seed box 101. A centrifugal fan 103 is connected to the upper side wall of the downward-sloping pipe 102. The principle is to use a high-speed rotating impeller to accelerate the gas, then decelerate and change the flow direction, so that the kinetic energy is converted into potential energy. Several seeding tubes 104 are connected to the lower side wall of the downward-sloping pipe 102. A first infrared counter 105 is installed on the side wall of the downward-sloping pipe 102. The principle is that if an object passes through the middle of a transmitter and a receiver, it will block the light and output a pulse signal to trigger the counting circuit. A valve 106 is installed at the upper end of the seeding tube 104. A fixing rod 107 is fixedly connected to the upper side wall of the downward-sloping pipe 102. A pipe is fixedly connected to the upper end of the fixing rod 107. The seed box 101 has a pair of scrapers 110 slidably connected inside the seed box 109. A brush 111 is fixedly connected to the lower surface of the scrapers 110. A pair of linkage plates 112 are fixedly connected between the two scrapers 110. A lead screw 113 is threadedly connected to the scrapers 110. A motor box 114 is fixedly connected to the right surface of the seed box 101. A first motor 115 is placed inside the motor box 114. The output shaft of the first motor 115 is coaxially connected to the lead screw 113. A limit rod 116 is fixedly connected inside the seed box 101. The limit rod 116 is slidably connected to the scrapers 110. A groove 120 is opened on the lower surface of the seed box 101. A seed disc 121 is slidably connected to the groove 120. Several seed holes 122 are opened in the seed disc 121. A main valve 123 is fixedly connected to the lower surface of the groove 120. A funnel 124 is connected to the lower end of the main valve 123. The funnel 124 is connected to the lower inclined pipe 102.

[0027] During operation, first place barley seeds of similar size into the seed box 101, ensuring they are placed between the two scrapers 110. After the seeds are placed in, activate the first motor 115, causing the two scrapers 110 to slide left and right. At this time, the brushes 111 located under the scrapers 110 are in close contact with the inner wall of the seed box 101, sweeping the seeds into the seed holes 122. The seed holes 122 are slightly larger than the prepared seeds, allowing only one seed to fall in, but not two. Once the seed holes 122 are full... Afterward, the first motor 115 continues to drive the scraper 110 to move until the seed tray 121 is outside the two scrapers 110. At this point, the main valve 123 is opened, and the seeds in the seed hole 122 will pass through the main valve 123 and the funnel 124 into the downward inclined tube 102. The diameter of the downward inclined tube 102 is slightly larger than the seeds to ensure that the seeds fall one by one. The funnel 124 is designed to prevent blockage when entering the downward inclined tube 102. When the seeds begin to fall, the centrifugal fan 103 is turned on to help the seeds slide smoothly. The first seed slides into the rightmost seeding tube 104. The distance between adjacent seeding tubes 104 is fixed. The number of falling seeds is detected by a first infrared counter 105. When the first infrared counter 105 reads 2, the rightmost valve 106 is closed, preventing the second seed from sliding into the rightmost seeding tube 104. Instead, the seed falls onto the ground of the experimental field from the second seeding tube 104 from the right. When the first infrared counter 105 reads 3, the second valve 106 from the right is then closed. 6. Close the valve, allowing the third seed to fall from the third seeding tube 104 from the right onto the ground of the experimental field. Repeat the above operation until a seed slides down the lower end 104 of the leftmost seeding tube. At this point, close the main valve 123 and reopen all the branch valves 106. Through the above steps, it is ensured that each seed pit in this row has a seed, and the distance between the seeds is equal. After the first row is planted, move the entire device forward a fixed distance. When pushing to the second row, repeat the steps for planting the first row.

[0028] Please see Figure 1 and Figure 5 Based on the above, it is further described that a fertilizer tank 130 is fixedly connected to the upper surface of the placement plate 100, a fertilizer pipe 131 is connected to the lower side of the fertilizer tank 130, a discharge valve 132 is installed on the side wall of the fertilizer pipe 131, a number of discharge pipes 133 are connected to the lower side wall of the fertilizer pipe 131, and a fixing column 134 is fixedly connected to the upper side wall of the fertilizer pipe 131. The upper end of the fixing column 134 is fixedly connected to the pipe box 109, which facilitates fertilization of the experimental field at the same time as sowing, simplifies the experimental work procedure, and improves the efficiency of breeding experiment work.

[0029] Please see Figure 5 and Figure 6Furthermore, the fertilizer hopper 130 is fixedly connected to a hopper cover 138 on its upper surface. A second motor 135 is installed on the upper surface of the hopper cover 138. The output shaft of the second motor 135 passes through the hopper cover 138 and is coaxially connected to a rotating rod 136. Several stirring fans 137 are fixedly connected to the side wall of the rotating rod 136, which facilitates the mixing of various fertilizers.

[0030] Please see Figure 2 and Figure 3 It is worth noting that, since the leftmost seed tube 104 needs to be observed with the naked eye, but for ease of use, a second infrared counter 140 is installed on the side wall of the leftmost seed tube 104 to help personnel observe it through infrared technology.

[0031] Please see Figure 1 and Figure 2 In addition, to prevent soil compaction during sowing, a horizontal column 150 is fixedly connected to the inner wall of the pipe box 109, and several tillage plows 151 are rotatably connected to the side wall of the horizontal column 150, thereby making the soil more loose.

[0032] Please see Figure 1 and Figure 8 In addition, when the device moves, it may put pressure on the ground, so a pair of rotating columns 160 are fixedly connected to the left and right sides of the pipe box 109. The rotating columns 160 are slidably connected to the rotating wheels 161, and the rotating wheels 161 are driven by the thick track 162, so as to prevent the ground from hardening when moving.

[0033] Please see Figure 1 and Figure 8 As mentioned above, the distance the device moves needs to be the same. In addition, in order to ensure that the device moves the same distance each time, several marker posts 170 are fixedly connected to the surface of the thick track 162 away from the pipe box 109. T-shaped markers 171 are fixedly connected to the left and right surfaces of the pipe box 109, thus providing a reference for the distance of the device's movement.

[0034] Please see Figure 1 and Figure 5 In addition, to facilitate the overall movement of the device, a handle 180 is fixedly connected to the upper surface of the placement plate 100, and a traction hook 181 is fixedly connected to the left surface of the placement plate 100.

[0035] In this embodiment, the barley seeding device for uniform sowing in the barley breeding experiment is used as follows: First, barley seeds of similar size are placed into the seed box 101, positioned between the two scrapers 110. After the seeds are placed, the first motor 115 is activated, causing the two scrapers 110 to slide left and right. At this time, the brushes 111 under the scrapers 110 are in close contact with the inner wall of the seed box 101, sweeping the seeds into the seed holes 122. The seed holes 122 are slightly larger than the prepared seeds, just large enough to hold one seed but not two. Once the seed holes 122 are full of seeds, the first motor 115 continues to move the scrapers 110 until the seed tray 121 is outside the two scrapers 110. At this point, the main valve is opened. Seeds in seed hole 122 pass through main valve 123 and funnel 124 into inclined tube 102. The inclined tube 102 is slightly wider than the seeds to ensure they fall one by one. Funnel 124 prevents blockage when entering the inclined tube 102. Centrifugal fan 103 is activated to assist the seeds in sliding smoothly as they begin to fall. The first seed slides into the rightmost seeding tube 104. The distance between adjacent seeding tubes 104 is fixed. A first infrared counter 105 detects the number of falling seeds. When the first infrared counter 105 reads 2, the rightmost branch valve 106 closes, preventing the second seed from sliding into the rightmost seeding tube 104. Instead, seeds begin to fall from the right. The second seeding tube 104 falls onto the ground of the experimental field. When the first infrared counter 105 reads 3, the second branch valve 106 from the right is closed, allowing the third seed to fall onto the ground from the third seeding tube 104 from the right. This process is repeated until the second infrared counter 140 reads 1, indicating that all seeding tubes 104 have dropped a seed. At this point, the main valve 123 is closed and all branch valves 106 are reopened. Through these steps, it is ensured that each seeding hole in this row has a seed, and the distance between the seeds is equal. After the first row is planted, the entire device is pushed forward by the handle 180. The thick tracks 162 prevent the device from being overloaded due to its weight. The large size of the field compacts the soil, ensuring equal spacing between adjacent marker posts 170. While pushing the device, the distance between the T-shaped marker pole 171 and the marker posts 170 is observed to ensure equal spacing between each row of seeds. When pushing to the second row, the sowing process for the first row is repeated. To prevent soil compaction from hindering seed germination, the tillage plow 151 is used to till the ground as the entire device moves. Simultaneously with sowing, the discharge valve 132 can be opened to allow fertilizer to fall from the discharge pipe 133 onto the ground. If multiple fertilizers are needed, they can be poured into the fertilizer tank 130 before the second motor 135 operates, driving the mixing fan 137 to rotate and mix the fertilizers. If the experimental field area is too large for manual sowing, the device cannot be manually pushed.It can be moved by connecting to the tractor head via the towing hook 181. The main valve 123, branch valves 106, and the first infrared counter 105 ensure that the number of seeds falling to the ground from each seeding tube 104 is consistent, thus avoiding missed sowing or double sowing. Simultaneously, the equal distance between each seeding tube 104 ensures that the distance between each seed is also consistent.
