[0021] The structure of the present utility model is described in detail below with reference to the accompanying drawings.

[0022] like Figures 1 to 4 As shown, an embodiment of the utility model provides a sowing device for tomato breeding, comprising a machine body 1, a conveying platform 2, a sowing device 3 and a pit pressing device 4. The conveying platform 2 is arranged at the upper end of the machine body 1 and is fixedly connected to the conveying body 1. The sowing device 3 is arranged above the conveying platform 2 and is fixedly connected to the conveying platform 2. The pit pressing device 4 is arranged behind the sowing device 3 and is fixedly connected to the conveying platform 2. Positioning devices 5 are provided on both sides of the conveying platform 2, and the two positioning devices 5 are fixedly connected to the conveying platform 2.

[0023] refer to Figure 1 and Figure 2 The positioning device 5 includes a push-clamp assembly 51, a clamping plate assembly 52 and a locking assembly 53. There are two push-clamp assemblies 51, which are respectively arranged at the front and rear ends of the right side of the conveying platform 2. The clamping plate assembly 52 is arranged on the left side of the two push-clamp assemblies 51. There are two locking assemblies 53, which are respectively arranged on the left and right sides of the rear end of the upper surface of the conveying platform 2.

[0024] The above solution is adopted: by providing two positioning devices 5, the plug tray is positioned and stabilized to prevent the plug tray from being unstable and deviating when it moves on the conveying platform 2 for sowing, thereby affecting sowing.

[0025] refer to Figure 1 、 Figure 2 and Figure 3The push-clamp assembly 51 includes a fixed seat 511, a sliding rod 512, a limiting plate 513 and a push spring 514. The fixed seat 511 is fixedly connected to the upper surface of the conveyor platform 2. There are two sliding rods 512, which are respectively arranged on the front and rear sides of the fixed seat 511. The left and right sides of the two sliding rods 512 extend out of the fixed seat 511 and are slidably connected to the fixed seat 511. The limiting plate 513 is fixedly connected to the right ends of the two sliding rods 512. There are two push springs 514, which are respectively sleeved on the left ends of the two sliding rods 512, and the right ends are fixedly connected to the left surface of the fixed seat 511.

[0026] The above solution is adopted: by providing a pushing and clamping assembly 51 to push the clamping plate assembly 52, it has the function of driving the two clamping plate assemblies 52 to push together, thereby playing a role in stabilizing the positioning of the hole tray.

[0027] refer to Figure 2 and Figure 3 The clamping plate assembly 52 includes a movable plate 521, a fixed rod 522 and an auxiliary wheel 523. The movable plate 521 is fixedly connected to the left end of the four sliding rods 512, and the right surface is fixedly connected to the left end of the four push springs 514. There are several fixed rods 522, and they are evenly arranged inside the movable plate 521. The upper and lower ends of several fixed rods 522 are respectively fixedly connected to the upper and lower end surfaces inside the movable plate 521. There are several auxiliary wheels 523, which are respectively sleeved on the surfaces of several fixed rods 522 and rotatably connected to the fixed rods 522. The right sides of several auxiliary wheels 523 extend out of the movable plate 521 and are movably connected to the movable plate 521.

[0028] The above solution is adopted: by setting a clamping plate assembly 52, which cooperates with the pushing and clamping assembly 51 to clamp and position the hole tray, and the auxiliary wheel 523 extends from one side of the movable plate 521 to contact and clamp the hole tray firmly. The coordinated rotation of the auxiliary wheel 523 does not affect the normal movement of the hole tray during clamping.

[0029] refer to Figure 1 、 Figure 2 and Figure 4The locking assembly 53 includes a placement slot 531, a positioning rod 532, a clamping head 533 and a spring 534. The placement slot 531 is opened on the upper surface of the conveyor platform 2. There are two positioning rods 532, which are respectively arranged on the front and rear sides of the placement slot 531. The lower ends of the two positioning rods 532 are fixedly connected to the bottom surface of the placement slot 531. The clamping head 533 is sleeved on the upper ends of the two positioning rods 532 and is slidably connected to the two positioning rods 532. The upper end of the clamping head 533 extends out of the placement slot 531 and is movably connected to the placement slot 531. There are two springs 534, which are respectively sleeved on the lower end surfaces of the two positioning rods 532. The upper and lower ends of the two springs 534 are respectively fixedly connected to the lower surface of the clamping head 533 and the bottom surface of the placement slot 531.

[0030] The above solution is adopted: by providing a locking assembly 53 to lock the clamping plate assembly 52, the clamping plate assembly 52 can be fixed to both sides of the conveying platform 2 by hand when it is not needed to be clamped firmly.

[0031] refer to Figure 1 and Figure 2 The surfaces of the rear ends of the two movable plates 521 that are away from each other are fixedly connected with docking parts 6, and the two docking parts 6 correspond to and adapt to the positions of the two locking components 53 respectively.

[0032] The above solution is adopted: by setting docking parts 6 on the surfaces away from each other at the rear ends of the two movable plates 521, which are used to cooperate with the two locking assemblies 53 when the clamping plate assembly 52 is recovered, so as to recover and lock the clamping plate assembly 52.

[0033] refer to Figure 1 and Figure 2 The rear ends of the two movable plates 521 are fixedly connected with an arc plate 7.

[0034] The above solution is adopted: arc plates 7 are fixedly connected to the rear ends of the two movable plates 521 to facilitate the placement of the hole tray between the clamping plate assemblies 52 on both sides.

[0035] The working principle of this utility model:

[0036] When sowing, the hole tray containing the culture soil is placed on the conveying platform 2 from the rear of the conveying platform 2, and the hole tray is pushed forward. When the hole tray moves, the two arc plates 7 are squeezed on both sides, so that the movable plate 521 moves to both sides, and the sliding rod 512 is driven to move to both sides in the fixed seat 511. At the same time, the push spring 514 is squeezed. When the hole tray moves forward, the push spring 514 cooperates with the fixed seat 511 to give a certain thrust to the movable plate 521, so that the auxiliary wheel 523 clamps the two sides of the hole tray firmly. The movement of the hole tray drives the auxiliary wheel 523 to rotate on the surface of the fixed rod 522 to reduce the friction caused by the clamping, so that the hole tray can move normally, thereby being stable. When the holding plate assembly 52 is recovered and locked, the movable plate 521 is pulled to both sides, and the docking member 6 squeezes the clamping head 533 at the same time, so that the clamping head 533 is squeezed into the positioning rod 532 to prevent it from moving into the placement groove 531, and at the same time squeezes the spring 534. After the movable plate 521 is pulled to the limit, the clamping head 533 will correspond to the inside of the docking member 6. At this time, the spring 534 will rebound and push the clamping head 533 upward into the docking member 6 to position and fix the docking member 6, and then recover and lock it. When unlocking, the clamping head 533 is pressed downward into the placement groove 531 to move the clamping head 533 out of the docking member 6, thereby releasing the recovery and fixation of the clamping plate assembly 52.

[0037] In summary, the sowing equipment for tomato breeding solves the problem of the existing hole seeder in which the hole tray cannot be positioned firmly when sowing in the hole tray. If the hole tray is unstable on the conveying platform, it is very easy to deviate and run away, which will directly affect the sowing accuracy.
