Description

Technical Field

[0001] The invention relates to the technical field of tomato seed pre-sowing treatment, in particular to a tomato seed pre-treatment device. Background Art

[0002] Tomato seeds are one of the most important ways to spread tomato pathogens. The pathogens carried by tomato seeds can directly infect seed buds and seedlings, causing seed and seedling death, and provide a source of bacteria for later disease, which is the root cause of tomato field diseases. Pathogens include fungi, bacteria and viruses. These pathogens are mixed in the tomato seeds in the form of spores, mycelium, and bacteria, attached to the surface of tomato seeds, and even lurking in the seed coat tissue or embryo. Therefore, sterilization and disinfection of tomato seeds before sowing is an indispensable measure to reduce the spread of diseases and prevent the occurrence of field diseases. Many tomato seed manufacturers need to sterilize and disinfect tomato seeds before selling them, that is, pre-treatment of tomato seeds.

[0003] There are many ways to disinfect tomato seeds. The most common ones are hot water soaking and chemical disinfection. Chemical disinfection can be carried out using trisodium phosphate solution, formalin solution, potassium permanganate solution, copper sulfate solution or streptomycin solution. Different chemical solutions have different treatment methods for seeds. For potassium permanganate solution as the chemical, just pour the tomato seeds into the chemical solution and soak them for about 25 minutes, then take them out and wash them with clean water.

[0004] After receiving the tomato seeds, the tomato seeds are generally packed in breathable bags such as burlap bags. The tomato seeds are relatively small. In order to facilitate the pouring and taking out of the sterilization tank, the tomato seeds and the packaging bags are generally immersed in the chemical solution. Although this improves the loading and unloading efficiency of the tomato seeds during the sterilization process, in fact, during the sterilization process, the tomato seeds and the packaging bags are difficult to quickly immerse in the chemical solution due to their own dry characteristics and the residual gas in the packaging bags. If they are immersed in the chemical solution in time, during the immersion process, as the effective ingredients of the chemical solution on the inside of the packaging bag are consumed, the effective ingredients of the chemical solution on the outside of the packaging bag are difficult to enter the inside of the packaging bag in time due to the obstruction of the packaging bag, thereby affecting the sterilization effect of the tomato seeds inside the packaging bag.

DETAILED DESCRIPTION

[0029] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0030] like Figures 1 to 7 As shown, the present invention includes the following embodiments:

[0031] Embodiment 1, a tomato seed pretreatment device, comprising a barrel body 1 and a base 2 at the bottom of the barrel body 1; a water valve 11 is provided through the lower position of the inner and outer walls of the barrel body 1; an inverted cylinder 3 is provided at the upper end of the barrel body 1; the inverted cylinder 3 opens downward; the inner side of the inverted cylinder 3 is movably sealed and connected to a movable disk 4; the upper surface of the movable disk 4 is connected to the bottom wall of the inverted cylinder 3 by a tension spring 41; the upper surface of the movable disk 4 is fixedly connected to a movable rod 42; the movable rod 42 is connected to the upper side of the movable disk 4 The end passes through the inverted cylinder 3 and is movably and sealedly connected to the inverted cylinder 3; the upper surface of the base 2 is fixedly connected to the electric push rod 21; the upper end of the electric push rod 21 is fixedly connected to the upper end of the movable rod 42 through the connecting rod 22; the inner bottom wall of the inverted cylinder 3 is connected to the inner bottom wall of the barrel body 1 through the side tube 5; the side tube 5 is located on the side of the barrel body 1 and can be extended and retracted; a one-way liquid inlet valve is provided at one end of the side tube 5 close to the inverted cylinder 3; the movable disk 4 is penetrated by a one-way liquid outlet hole 43 from top to bottom.

[0032] In this embodiment, there are a plurality of one-way liquid outlet holes 43 ; the one-way liquid outlet holes 43 are close to the movable rod 42 ; and the one-way liquid outlet holes 43 are inclined in the vertical direction.

[0033] During operation, after closing the water valve 11, the worker pours clean water into the barrel body 1 along the upper port of the barrel body 1, then adds the agent to form a drug solution of suitable concentration, and then places the tomato seeds together with the sack into the barrel body 1. The sack is a water-permeable and breathable packaging bag. There are gaps inside the packaging bag and inside the tomato seeds to form gas, so the tomato seeds and the packaging bag will float on the surface of the solution in the barrel body 1. Then, after opening the opening of the packaging bag, the opening of the packaging bag is turned outward and put on the edge of the upper port of the barrel body 1, and then the electric push rod 21 is controlled to shorten, and the electric push rod 21 will drive the connecting rod 22 during the shortening process. The movable rod 42 moves downward, and the movable rod 42 will drive the fixed movable plate 4 to move downward during the downward movement. During the downward movement of the movable plate 4, the inverting tube 3 moves downward with the movable plate 4. In the initial state, the movable plate 4 is located near the inner bottom wall of the inverting tube 3 under the pulling of the tension spring 41. As the inverting tube 3 moves downward, the inverting tube 3 will contact the upper end of the barrel body 1 through the bag opening of the packaging bag. The lower end of the inverting tube 3 and the upper end of the barrel body 1 press the bag opening of the packaging bag tightly, thereby fixing the bag opening of the packaging bag and preventing the bag opening of the packaging bag from sliding into the barrel body 1, causing tomato seeds to scatter out of the packaging bag and affecting subsequent unloading.As the mouth of the packaging bag is compressed, the inverted tube 3 cannot move further downward, and the electric push rod 21 drives the connecting rod 22 and the movable rod 42 to move downward continuously. Movement will occur between the movable rod 42 and the inverted tube 3, and the movable rod 42 is movably sealed and connected to the inverted tube 3. In the process of the movable plate 4 being driven downward by the movable rod 42, the space between the movable plate 4 and the inner bottom wall of the inverted tube 3 will become larger to form a negative pressure. The space between the upper surface of the movable plate 4 and the inner bottom wall of the inverted tube 3 is called an active cavity. In the process of the active cavity space becoming larger to form a negative pressure, the pharmaceutical solution in the barrel body 1 will enter the active cavity along the side tube 5. After the electric push rod 21 drives the movable plate 4 to move downward to the limit position on the inner side of the inverted tube 3, the electric push rod 21 drives the movable plate 4 to move upward on the inner side of the inverted tube 3. In order to ensure that the bag opening of the packaging bag is compressed by the lower end of the inverted cylinder 3 and the upper end of the barrel body 1, the tension spring 41 is also in a pulled state after the movable disk 4 moves upward. During the upward movement of the movable disk 4, the medicinal solution in the movable cavity will be discharged along the inclined one-way liquid outlet hole 43 and fall on the inner side of the packaging bag. After entering the inner side of the packaging bag, the medicinal solution quickly disperses the accumulated tomato seeds, so that the central tomato seeds are dispersed toward the edge. The tomato seeds sink quickly after being wetted, and the packaging bag sinks quickly with the entry of the medicinal solution. In addition, after the solution at the bottom of the packaging bag is drawn away at the lower end of the side tube 5, the packaging bag will also move downward. As the solution is added to the inner side of the packaging bag, the packaging bag will also move downward under the action of gravity, thereby achieving rapid immersion of the tomato seeds and the packaging bag. The tomato seeds are immersed in the medicinal solution in the barrel body 1, and the medicinal solution will pass through the inside of the packaging bag into the barrel body 1, and will be sprayed out from the one-way liquid outlet 43 again under the suction of the side pipe 5, so that the tomato seeds can fully contact with the medicinal solution in the barrel body 1, while simple stirring cannot ensure that the medicinal solution can smoothly pass through the packaging bag into the inside and contact with the tomato seeds. Therefore, this solution is obviously better than the existing stirring method. The movable disk 4 moves up and down in a cycle during the tomato seed sterilization process. As the medicinal solution contacts the tomato seeds, the tomato seeds are sterilized. After the tomato seeds are sterilized, the electric push rod 21 is controlled to extend and drive the movable rod 42 and the movable disk 4 to move up. During the upward movement of the movable disk 4, it will approach the inner bottom wall of the inverted cylinder 3, and when pulling After the spring 41 contracts to the limit position, the movable disk 4 will drive the inverted cylinder 3 to move up and away from the mouth of the packaging bag. After the inverted cylinder 3 is away from the barrel body 1, the worker will tighten the mouth of the packaging bag, lift the packaging bag, and take it away from the top of the barrel body 1 after draining, and sterilize the next package of tomato seeds. A component concentration detection component is set in the barrel body 1, which can detect the concentration of the active ingredients of the medicine. When the concentration of the medicine solution inside the barrel body 1 is lower than the standard value, the solution can be added or replaced. The valve can be opened when the solution is replaced. In addition, the concentration of the active ingredients of the medicine solution in the barrel body 1 can also be manually controlled based on experience, that is, according to the sterilization batch or use evaluation rate of the tomato seeds in the packaging bag, the sterilized tomato seeds need to be washed with clean water;

[0034] The present invention turns the packaging bag inside out and puts it on the upper end of the barrel body 1, which is then pressed by the inverted cylinder 3, and cooperates with the movement of the movable plate 4, so that the medicinal solution in the barrel body 1 is drawn into the inner side of the packaging bag to contact the tomato seeds. Compared with the existing method in which the medicinal solution inside the barrel body 1 passes through the packaging bag from the outside to the inside to contact the tomato seeds, the present invention has better sterilization efficiency and effect.

[0035] In Example 2, the inner wall of the barrel body 1 is in movably contact with the drain cylinder 6; the drain cylinder 6 is provided with drain holes 61 inside and outside; the upper end of the drain cylinder 6 is fixedly connected to a drain ring 62 facing outward; the outer diameter of the drain ring 62 is larger than the outer diameter of the barrel body 1; the drain ring 62 is placed on the upper end of the barrel body 1; the upper end of the barrel body 1 is provided with a lower annular groove 12; the lower annular groove 12 is movably sealed and connected to an annular sleeve 7; the upper surface of the base 2 is fixedly connected to the hydraulic pump 24; the hydraulic pump 24 is connected to the inner bottom wall of the lower annular groove 12.

[0036] In this embodiment, an upper annular groove 63 is provided on the lower surface of the drain ring 62; the upper annular groove 63 is aligned with and corresponds to the upper end of the annular sleeve 7; the upper end of the annular sleeve 7 can be inserted into the upper annular groove 63 and movably cooperate with the upper annular groove 63; the upper surface of the movable disk 4 is fixedly connected to the control tube 44; a control valve is provided inside the control tube 44; the control tube 44 passes through the movable disk 4 at the lower end and passes through the inverted tube 3 at the upper end; the inverted tube 3 is movably and sealedly connected to the control tube 44.

[0037] During operation, in the initial state, the hydraulic pump 24 will inject oil into the lower annular groove 12, so that the annular sleeve 7 will move up to the limit position without separating from the lower annular groove 12, and the upper end of the annular sleeve 7 will abut against the upper annular groove 63 on the lower surface of the drain ring 62, so that the drain ring 62 moves up to the limit position with the annular sleeve 7, and the drain ring 62 will drive the drain cylinder 6 to separate from the liquid surface of the pharmaceutical solution on the inner side of the barrel body 1, and the electric push rod 21 will also drive the inverted cylinder 3 to move up to the limit position, leaving space between the inverted cylinder 3 and the drain ring 62 for loading and unloading bagged tomato seeds. When a new batch of tomato seeds needs to be sterilized, the packaging bag containing the tomato seeds is placed on the inner side of the drain cylinder 6, and then the bag mouth of the packaging bag is opened and outside It is flipped over the drain ring 62, and then the electric push rod 21 is controlled to shorten to drive the connecting rod 22 and the movable rod 42 to move downward. During the downward movement of the movable rod 42, the movable plate 4 and the inverting tube 3 are driven to move downward, and the lower end of the inverting tube 3 contacts the bag opening of the packaging bag, so that the bag opening of the packaging bag is clamped between the lower end of the inverting tube 3 and the drain ring 62, and the lower end of the inverting tube 3 and the drain ring 62 keep clamping the bag opening of the packaging bag, and then the hydraulic pump 24 pumps away the oil at the bottom of the lower annular groove 12 while controlling the electric push rod 21 to shorten. During the process of the hydraulic pump 24 pumping away the oil in the lower annular groove 12, the annular sleeve 7 will move downward, and the electric push rod 21 shortens while driving the connecting rod 22 to move downward, and the downward speed of the annular sleeve 7 is the same as the downward speed of the connecting rod 22 , the drain cylinder 6 will drive the packaging bag containing tomato seeds to move down and enter the inner side of the barrel body 1. During the shortening process of the electric push rod 21, the control valve in the control tube 44 is controlled to open, so that the gas inside the barrel body 1 and the inner side of the inverted cylinder 3 will flow out along the control tube 44, until the drain ring 62 moves down and contacts the upper port of the barrel body 1, the hydraulic pump 24 is stopped, the control tube 44 is closed, and then the electric push rod 21 is controlled to shorten and then extend again, so that the movable disk 4 moves down and then up. During the movement of the movable disk 4, the space of the active cavity changes, so that the pharmaceutical solution inside the barrel body 1 is drawn into the active cavity along the side tube 5, and is sprayed along the one-way liquid outlet 43 to the inner side of the packaging bag to contact the tomato seeds for sterilization. After the sterilization is completed, The control tube 44 is opened, the electric push rod 21 is extended to drive the movable disk 4 close to the limit position of the inner bottom wall of the inverted tube 3, and then the hydraulic pump 24 is controlled to inject oil into the lower annular groove 12 to realize the upward movement of the annular sleeve 7. During the upward movement of the annular sleeve 7, the connecting rod 22 is driven by the electric push rod 21 to drive the movable rod 42, the movable disk 4 and the inverted tube 3 to move upward. In this way, in the process of keeping the bag mouth of the packaging bag clamped, the drain cylinder 6 moves upward with the upward movement of the annular sleeve 7, and the external air enters the inverted tube 3 along the control tube 44. The drain cylinder 6 will lift the inner packaging bag away from the pharmaceutical solution to realize automatic drainage. After the drainage is completed, the inverted tube 3 is controlled to move upward, the bag mouth of the packaging bag is unclamped, and the bag mouth of the packaging bag is tied and taken out from the inner side of the drain cylinder 6.After draining, the pharmaceutical solution flows back to the barrel 1 for recycling. The annular sleeve 7 shields the splashed solution during the draining process. The gap between the drain cylinder 6 and the annular sleeve 7 allows the drained water to flow along the gap between the outer wall of the drain cylinder 6 and the inner wall of the annular sleeve 7, thereby accelerating the draining speed of the tomato seeds in the packaging bag. The workers will regularly remove the drain cylinder 6 from the upper end of the annular sleeve 7, so that the annular sleeve 7 is removed from the upper annular groove 63, and clean the drain cylinder 6 and the inside of the barrel 1. ;

[0038] In Example 3, the side tube 5 is composed of an upper side tube 51 and a lower side tube 52; the lower end of the upper side tube 51 and the upper end of the lower side tube 52 are movably sealed and nested with each other; the upper side tube 51 is out of contact with the lower side tube 52 after the drain tube 6 moves up.

[0039] In this embodiment, air holes 71 are provided through the inner and outer walls of the annular sleeve 7 ; the gas inside the annular sleeve 7 can be discharged through the air holes 71 .

[0040] In this embodiment, the end of the air hole 71 close to the central axis of the annular sleeve 7 is lower than the end of the air hole 71 away from the central axis of the annular sleeve 7; the air hole 71 is arranged away from the drain ring 62; the air hole 71 exposes the lower annular groove 12 after the annular sleeve 7 moves up; the air hole 71 enters the lower annular groove 12 after the annular sleeve 7 moves down.

[0041] During operation, after the drain cylinder 6 is at the upper limit position, the tomato seeds to be sterilized and the packaging bag are loaded into the inner side of the drain cylinder 6. After the bag mouth of the packaging bag is turned outward, the electric push rod 21 is controlled to shorten, and the lower end of the inverted cylinder 3 and the upper end of the drain ring 62 are pressed tightly against the bag mouth of the packaging bag. Then, the annular sleeve 7 and the inverted cylinder 3 are controlled to move downward. During the downward movement of the inverted cylinder 3, the upper side tube 51 will be driven to insert into the lower side tube 52. As the inverted cylinder 3 continues to move downward, the gas inside the inverted cylinder 3 flows out along the control tube 44. After the drain cylinder 6 moves to the limit position, the control tube 44 is closed, and then the movable disk 4 is controlled to move, so that the volume of the movable cavity changes. The pharmaceutical solution inside the barrel body 1 is sprayed out along the side lower tube 52, the side upper tube 51, the one-way liquid inlet valve, the movable cavity and the one-way liquid outlet hole 43. After the sterilization is completed, the annular sleeve 7 and the inverted cylinder 3 move up, and the side upper tube 51 is separated from the side lower tube 52 after the inverted cylinder 3 moves up. The air vent 71 is exposed from the lower annular groove 12 after the annular sleeve 7 moves up, and the outside gas enters the inside of the inverted cylinder 3 along the opened control tube 44. After the annular sleeve 7 moves up to the limit position, the control tube 44 is closed, and then the bag mouth of the packaging bag is controlled to be clamped, while the movable disk 4 is controlled to move back and forth in the vertical direction. The movable disk 4 is in the inverted cylinder 3. During the downward movement, external gas enters the active cavity along the upper side tube 51 and the one-way air inlet valve. During the upward movement of the movable disk 4, the space in the active cavity will be reduced. The gas in the active cavity will be ejected along the one-way liquid outlet hole 43 and impact the tomato seeds in the packaging bag. The airflow will impact the tomato seeds inside the packaging bag from the inside to the outside, accelerating the drainage of the tomato seeds. The droplets on the tomato seeds will pass through the packaging bag and the drain cylinder 6 and flow back into the barrel body 1. The droplets on the annular sleeve 7 will flow into the barrel body 1. The gas will pass through the packaging bag and the drain cylinder 6 from the inside to the outside and be discharged along the air vents 71. In this process, the pressure of the gas is relatively small. It is enough to lower the liquid level in the barrel 1. The end of the air hole 71 close to the center of the annular sleeve 7 is lower than the end away from the center of the annular sleeve 7. Therefore, it is difficult for the liquid droplets to flow away along the air hole 71 with the gas. In order to further prevent the liquid droplets from flowing out, a receiving groove is provided at the opening position of the lower end of the air hole 71. An annular elastic ring is provided in the receiving groove. The elastic ring protrudes from the lower end of the air hole 71, so that the liquid droplets are not easy to pass through the lower end of the air hole 71. The elastic ring can be pressed into the lower annular groove 12 with the annular sleeve 7 and then placed in the receiving groove for storage. After the tomato seeds in the packaging bag are drained, the inverted cylinder 3 is removed and the tomato seeds can be taken out.

[0042] In this embodiment, the airflow is controlled to impact the tomato seeds in the packaging bag from the inside to the outside, thereby improving the drainage efficiency of the tomato seeds and the sterilization efficiency of the tomato seeds.

[0043] Embodiment 4, the inner wall of the inverted cylinder 3 is provided with a spiral groove 31; the movable block 32 is movably sealed in the spiral groove 31; the movable block 32 is fixedly connected to the outer wall of the movable disk 4; the inverted cylinder 3 is composed of a top disk 33 and a side sleeve 34; the top disk 33 is rotatably sealed and connected to the side sleeve 34; the movable disk 4 drives the side sleeve 34 to rotate during the up and down movement inside the side sleeve 34; the upper annular groove 63 is rotatably sealed with the upper end of the annular sleeve 7.

[0044] In this embodiment, the lower port of the inverted cylinder 3 and the upper surface of the drain ring 62 are both configured to be corrugated; the lower port of the inverted cylinder 3 and the upper surface of the drain ring 62 are meshed with each other and in sealing contact.

[0045] During operation, when the drain ring 62 is in the upper limit position, the tomato seeds to be sterilized are placed together with the packaging bag into the inner side of the drain barrel 6, and after the bag mouth of the packaging bag is turned outward and sleeved on the upper surface of the drain ring 62, the inverted barrel 3 is controlled to move downward so that the lower end of the inverted barrel 3 and the upper surface of the drain ring 62 clamp the bag mouth of the packaging bag, and then the control tube 44 is opened to control the drain barrel 6 to move downward until the drain barrel 6 moves to the limit position, and the control tube 44 is closed to control the movable disk 4 to move back and forth in the vertical direction. During the up and down movement of the movable disk 4, on the one hand, the pharmaceutical solution in the barrel body 1 is drawn out along the side tube 5 and then sprayed along the one-way liquid outlet 43; on the other hand, during the up and down movement of the movable disk 4, the movable block 32 is driven to move, and the movable disk 4, the movable rod 42, the connecting rod 22 and the electric push rod 21 cannot rotate. After the spiral groove 31 moves, the side sleeve 34 rotates, and the rotation of the side sleeve 34 drives the meshing drain ring 62 to rotate, and the rotation of the drain ring 62 drives the drain barrel 6 to rotate. The tomato seeds rotate with the rotation of the packaging bag, and the accumulated tomato seeds are scattered toward the surroundings under the action of centrifugation, thereby accelerating the contact with the pharmaceutical solution sprayed from the one-way liquid outlet 43, so that the tomato seeds are quickly wetted, and the sterilization efficiency is further improved; after the sterilization is completed, the drain barrel 6 moves up to the limit position to drain the tomato seeds in the packaging bag, and while keeping the annular sleeve 7 stationary, the movable disk 4 is controlled to move up and down again, so that the side sleeve 34, the drain ring 62 and the drain barrel 6 rotate, so that the droplets attached to the tomato seeds in the packaging bag are thrown away under the multiple effects of centrifugal force, airflow and gravity, so that the drainage efficiency is further improved.
