[0029] The present invention is further described below in conjunction with the accompanying drawings and examples. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Needless to say, those skilled in the art will recognize that the described embodiments may be modified in various ways without departing from the spirit and scope of the present invention. Therefore, the drawings and descriptions are illustrative in nature and are not intended to limit the scope of protection of the claims.

[0030] like Figure 1 and Figure 2 As shown, the automatic temperature-controlled sample delivery device for grain samples includes a sample collection channel 10, a sample collection box 20, a workbench 30, a heater 40, a collection box driving mechanism 50 and a controller (not shown in the figure), and the controller controls the connection between the heater 40 and the collection box driving mechanism 50.

[0031] refer to Figure 1 and Figure 5 By setting a sample collection channel 10, sample collection after the housing is installed can be facilitated. The sample collection channel 10 has a receiving port 11 and a discharge port 12. A temperature sensor 13 for detecting the sample temperature is provided at the discharge port 12 of the sample collection channel 10;

[0032] The workbench 30 is provided with a sampling station and a delivery station; the sampling station is located at the discharge port 12 of the sample collection channel 10, a carrying platform 31 is provided at the sampling station, and a weight sensor 32 is provided at the carrying platform 31, so that in the initial state, the sample collection box 20 is placed at the carrying platform 31 of the sampling station; when it is necessary to collect samples, a sample of a certain weight is placed in the receiving port 11 of the sample collection channel 10, and the sample enters the sample collection box 20 from the discharge port 12 along the sample collection channel 10, the sample temperature of the collected sample can be detected by the temperature sensor 13, and whether the weight of the sample in the sample collection box 20 meets the set requirements can be detected by the weight sensor 32, thereby sending a control signal to the controller.

[0033] A sample delivery port 33 is provided at the delivery station of the workbench 30 , and a guide hopper can be installed at the sample delivery port 33 so as to deliver the sample to the grain detection and analysis equipment located below it.

[0034] refer to Figure 4 The sample collection box 20 includes a box body 21, and a discharge port that can be opened and closed is provided at the bottom of the box body 21; in this embodiment, a bottom plate 22 is hinged at the bottom of the box body 21, so that when the sample collection box 20 reaches the sample delivery port 33 of the delivery station, the bottom plate 22 will naturally open downward from the box body 21 around the hinge axis due to its own gravity, so that the discharge port is in an open state; when the sample collection box 20 has delivered the sample and returns to the carrier 31 from the sample delivery port 33, the bottom plate 22 will turn upward around the hinge axis into the box body 21 under the interference of the carrier 31, so that the discharge port is in a closed state, so that the structural design is simple, and the sample delivery can be realized without the need for an additional control valve, and the operation and control are convenient. Of course, the opening and closing method of the discharge port of the sample collection box 20 can also be realized by other structures, which should all belong to the protection scope of the utility model.

[0035] The heater 40 is installed on one side of the workbench 30, and the heater 40 has a heating chamber for accommodating the sample collection box 20; the heater 40 is preferably a microwave heater, which can improve the heating speed and heating uniformity. For operational safety and to facilitate the sample collection box 20 to enter and exit the heating chamber, the microwave heater has a safety door 41 that can be lifted and opened, and the safety door 41 is connected to a lifting drive mechanism 42. When the heating is working, the safety door 41 is controlled to rise and close, and when the sample collection box 20 needs to enter and exit the heating chamber, the safety door 41 is controlled to fall and open.

[0036] For ease of operation, the heater 40 is arranged adjacent to the carrier platform 31, and a transition plate 34 is provided between the heating chamber of the heater 40 and the carrier platform 31. The transition plate 34 is hinged to the carrier platform 31, so that the sample collection box 20 on the carrier platform 31 can be translated into the heating chamber without obstacle through the transition plate 34; and when the safety door 41 needs to rise and close, under the action of the upward thrust of the safety door 41, the transition plate 34 is naturally pushed upward, thereby not affecting the closing of the safety door 41.

[0037] The collection box driving mechanism 50 can drive the sample collection box 20 to switch between the sampling station, the heating chamber and the delivery station. Figure 3 In this embodiment, the collection box driving mechanism 50 includes a clamping mechanism 51 for clamping the sample collection box and a displacement mechanism 52 for driving the clamping mechanism 51 to move forward and backward. The displacement mechanism 52 can be implemented by a linear module, which will not be described in detail here. The clamping mechanism 51 includes two clamping arms 511 arranged opposite to each other and a clamping arm driving mechanism 512 for driving the two clamping arms 511 to move closer or farther away. The clamping arm driving mechanism 512 can adopt a common driving mechanism such as a screw slide. The clamping arm 511 is equipped with a push plate 513 for pushing the sample collection box forward and a pull claw 514 for pulling the sample collection box backward. Reference Figure 4 In order to improve the operational stability during clamping and moving, a clamping groove 23 cooperating with the clamping arm 511 is provided on the outer wall of the box body 21. When the sample collection box 20 needs to be clamped and moved, the two clamping arms 511 move inwards relative to each other and are clamped in the clamping groove 23, the push plate 513 is located at the rear end of the sample collection box 20, and the pull claw 514 is located at the front end of the sample collection box 20. In this way, the sample collection box 20 is reliably clamped by the clamping mechanism 51, and then the sample collection box 20 can be driven to move forward and backward by the displacement mechanism 52. Of course, the collection box driving mechanism 50 can also adopt other structures to realize its driving function, which should all belong to the protection scope of the present utility model.

[0038] refer to Figures 1 to 5 , the working principle of the utility model is as follows:

[0039] In the initial state, the sample collection box 20 is placed on the carrier 31 of the sampling station; when it is necessary to collect samples, a sample of a certain weight is placed in the receiving port 11 of the sample collection channel 10, and the sample enters the sample collection box 20 from the discharge port 12 along the sample collection channel 10. The sample temperature of the collected sample can be detected by the temperature sensor 13, and the weight sensor 32 can detect whether the weight of the sample in the sample collection box 20 meets the set requirements, thereby sending a control signal. If the sample temperature is equal to or higher than the set temperature, the collection box driving mechanism 50 directly drives the sample collection box 20 to move to the delivery station, and the sample in the sample collection box 20 falls from the discharge port into the grain detection and analysis equipment 60 below; if the sample temperature is lower than the set temperature, the collection box driving mechanism 50 drives the sample collection box 20 to move to the heating chamber of the heater first, and the collected sample is heated to the set temperature by the heater, and then the collection box driving mechanism 50 drives the sample collection box to move to the delivery station, and the sample in the sample collection box 20 falls from the discharge port into the grain detection and analysis equipment 60 below. In this way, the device can preheat and automatically deliver the collected grain samples according to the detection needs, is not affected by the detection location and ambient temperature, is easy to operate and use, and is conducive to improving the accuracy of the detection data and the detection efficiency.
